The Buttar property is located northwest of the intersection of SE 174th Street and Cedar Avenue SE as shown on the Vicinity Map,Figure 1. The Buttar property is located in an area of historic underground coal mining. A coal mine hazard assessment is required by the City of Renton to evaluate the potential for ground subsidence and to provide building/facilities design measures, and/or delineate areas of the Buttar property to avoid building/facilities construction, as appropriate, and to mitigate for potential ground subsidence (Renton Municipal Code Title IV Development Regulations, Section J (Geologic Hazards), 2 (Special Studies Requirements)). PROJECT DESCRIPTION We understand that the property owner, Baljinder Buttar, is considering developing the approximately ten acre property for residential use. Based on discussions and information provided by Lafe Hermansen of Core Design, Inc. (Core) we understand that residential development along with access roads and utilities is proposed for the Buttar property. The specific layout of building lots and roads, and grading plans, are not known at this time. Mr. Hermansen provided ICE with the following property information: • Core Design, Inc., July 1, 2002, "Conceptual Site Plan, Cedar Avenue Property, Renton, Washington,"scale 1 inch=40 feet. The property layout is shown on the Site Plan and Coal Mine Location Map,Figure 2. BACKGROUND INFORMATION ICE reviewed documents and obtained historic aerial photographs of the site to aid in our geologic reconnaissance and evaluation of historic coal mining in this area. These documents and photographs are referenced as follows: • Morrison Knudsen, January 1985, "Engineering Investigation for the Renton, Washington Area," prepared for the U.S.Department of Agriculture, Office of Surface Mining. • Walker&Associates, Inc., 1936 and 1947, historical aerial photographs of the Buttar property area. • Warren, W.C., Norbisrath, H., Grivetti, R.M., and Brown, S.P., 1945, "Preliminary Geologic Map and Brief Description of the Coal Fields of King County, Washington," United States Geological Survey, 1 plate. • Washington State Department of Natural Resources, 1932, 1934 through 1938, 1940, 1942 through 1948, historic coal mine maps of the Springbrook area mines including surface features and underground mine workings. • Washington State Department of Natural Resources, undated, "Summary of Coal Production in King County,Washington,"by mine and year from 1888 through 1967, 1 plate. SCOPE OF SERVICES GENERAL ' The purpose of our services was to complete a coal mine hazard assessment and a geotechnical engineering evaluation of the Buttar property. Specifically, our services included: Icicle Creek Engineers 1 0429001/092402 COAL MINE HAZARD ASSESSMENT Information Review • Review available information concerning project site topography, geology, soil conditions and other relevant site characteristics. Published materials included geologic maps prepared by the U. S. Geological Survey(USGS), and a variety of maps published by the Washington State Department of Natural Resources. • Review available mine records to evaluate the location of the mined-out areas, together with the depth of mining, thickness of zone mined and mining methods. This information was reviewed in concert with ground surface topography to evaluate if there has been any surface expression or collapse of underground openings. The historic mine records included mine maps and published technical reports and historical literature regarding coal mining in King County and at the project site. • Review historical photographs (1936 and 1947) for evidence of the location of mining facilities on the 'surface for comparison with the historical documents and to aid our surface reconnaissance effort. • Surface reconnaissance mapping to identify mine openings such as adits or air shafts, together with stockpiles of tailings or other areas in which the original ground surface has been disturbed. In addition, we noted surface topographic anomalies that might indicate collapse of underground workings. • Conduct interviews, as appropriate, with individuals familiar with historic coal mining activities in the project area. • Mine mapping included superimposing the identified mines onto a project site base map. This map was then used to develop four geologic cross-sections showing the depth to mined-out areas and an interpretation of mine overburden conditions. Ground Proofing Program(Subsurface Exploration) • Explore the near-surface soils (up to 15 feet deep) by excavating 27 test pits (Test Pits TP-1 through • TP-27)using a track-mounted excavator. • Evaluate subsurface soil, bedrock and mine conditions by drilling thirteen test borings (Borings B-1 through B-13)across the shallow workings of the Springbrook No. 2 Mine. Coal Mine Hazard Assessment • Based on the findings of the information review and the ground proofing program, classify the mine hazards as either: 1) High Coal Mine Hazards, 2)Medium Coal Mine Hazards, or 3) Low Coal Mine Hazards. • Evaluate the potential for regional ground subsidence in High and Medium Coal Mine Hazard Areas (vertical ground subsidence, ground tilt and ground strain). • Develop mitigation for development within High and' Medium Coal Mine Hazard Areas, as appropriate. GEOTECHNICAL ENGINEERING EVALUATION • Review available test pit (Test Pits TP-1 through TP-27) and test boring(Borings B-1 through B-13) information as a basis for evaluating shallow (less than ten feet deep) subsurface conditions across the project site. • Provide a general location and an estimate of the quantity of unsuitable fill that occurs within the Buttar property. • Provide recommendations for site preparation and grading including stripping requirements, fill type, compaction criteria and reuse of on-site soils for structural fill. • Provide recommendations for structural fill including fill type and compaction criteria, and recommended fill slopes. Iciclie Creek Engineers 2 0429001/092402 • Provide recommendations for foundation support, including minimum footing dimensions, embedment depths and allowable soil bearing pressures. • Provide recommendations for support of on-grade floor slabs. • Provide recommendations for utility installation, including trench wall slopes, pipe bedding and trench backfill, and compaction criteria. • Provide recommendations for road subgrade preparation including an estimate of the CBR (California Bearing Ratio)used in pavement design. • Provide general recommendations for site erosion control and drainage measures considering the soil and ground water conditions encountered at the site. WETLAND HYDROLOGY EVALUATION • Provide an evaluation of the soils that underlie that possible wetland area in the vicinity of Lots 32, 33 and 37 as supporting information for the wetlands determination which is being conducted by Talasaea Consultants,LLC(Talasaea). GEOLOGIC SETTING Surficial geologic materials in the project area consist of fill deposits and glacial sediments. Landforms are primarily the result of the most recent glaciation. Tertiary age bedrock (Renton formation) underlies the entire Buttar property, and is relatively shallow (less than ten feet below the ground surface in the central and western portion of the property. The bedrock consists of sedimentary rocks composed primarily of sandstone, siltstone and coal. The Puget Sound basin has been occupied by continental glacial ice on at least four occasions during Pleistocene time, dating to 1.8 million years before present. Approximately 15,000 years ago, the most recent lobe of ice, known as the Vashon Lobe, advanced southward from western British Columbia into Puget Sound. As the ice advanced, the ground surface in this area was mantled by a soil deposit referred to as Glacial Till. Glacial Till (commonly referred to in this area as "hardpan") consists of a nonstra'tified, nonsorted deposit composed of mixture of silt, sand, gravel, cobbles and boulders. Glacial till is generally dense to very dense as a result of being overridden by about 3,000 feet of glacial ice. The glacial ice completely melted from the region about 10,000 years ago. Post-glacial erosion and surficial weathering further contributed to produce the present landforms. Grading activities associated with past coal mining within and adjacent to the Buttar property(discussed later in this report), have also modified the ground surface. SITE CONDITIONS SURFACE CONDITIONS Brian Beaman of ICE a conducted geologic reconnaissance of the site on March 28 and August 23, 2002. The Buttar property is located along a west-facing hillside above the Green River valley. The ground surface slopes down from east to west from about Elevation 329 feet along the east property line to about Elevation 174 feet along the west property line. The ground surface is relatively even-surfaced with slopes ranging from eight to 15 percent grade in the east portion of the site, then steepens to about an 18 to 27 percent grade in the central portion of the site, then flattens to a nearly level to eight percent grade in the western portion of the site. Currently, the Buttar property is primarily pastureland with scattered clumps of blackberry vines. A vacant house and barn are located in the northeast portion of the property. A wetland has been identified by Talasaea in the southwest portion of the site. A second "wetland" in the vicinity of Lots 32, 33 and 37 (based on the conceptual plan by Core, July 1, 2002) has been delineated by Talasaea in the west-central portion of the site, but is currently being further evaluated by Talasaea for additional characteristics (primarily soils) in making the final determination of its wetland status. The location of these wetlands based on the Core conceptual site plan (July 1, 2002) is shown on Figure 2. Icicle Creek Engineers 3 0429001/092402 The Buttar property is bordered by forested undeveloped land to the south and west, residential development to the north, and the unimproved easement of Cedar Avenue South and multi-family housing(Summerhill Apartments)to the east. No sinkholes (collapse features caused by the subsiding mine openings or underground mine workings discussed later in this report) were observed on the site. However, a backfilled abandoned mine opening was observed in the north-central portion of the site at the location shown on Figure 2. The historic mine map indicates that this was the former location of the main entry for the Springbrook No. 2 Mine (the Springbrook No. 2 Mine is described later in this report). The backfilled abandoned mine opening is roughly oval shaped measuring about 30 feet north-south and 15 feet east-west and varies in'depth from five to eight feet. Mounds of soil (fill) occur adjacent to the south and west sides of the sinkhole feature that suggest previous excavation has occurred at this site. Two other mine openings are located in this area as shown on Figure 2, but are backfilled and the ground surface leveled so are not visible. No other ground subsidence features, such as linear sags in the ground surface parallel to the underground mine workings,were observed. Surficial evidence of mine rock fill was observed in the central portion of the property (loose coal on the ground surface). Also, a conversation with an adjacent long-time property owner (Bob Miller) indicated that "piles of coal" existed in the central portion of the property that were later "leveled"by spreading this material out in the central to northwest portions of the property. 'Surface water was observed in March 2002 in the southwest portion of the site as shallow (less than three inches deep),ponded water in the previously described wetland area in the southeast portion of the site. The ponded water appears to fluctuate with rainfall and had dried out by late August 2002. Ponded water was also present in March 2002 in the base of the previously described sinkhole feature, but also had dried out by August 2002. SUBSURFACE CONDITIONS Shallow subsurface conditions (within 15 feet of the ground surface) at the Buttar property were explored by excavating a series of 27 test pits (Test Pits TP-1 through TP-27) across the Buttar property to depths ranging from 6 to 15 feet using a track-mounted excavator. In addition, 13 test borings (Borings B-1 through B-13) were completed (primarily in the area of shallow, abandoned coal mine workings)to depths ranging from 16 to 112 feet using track-mounted,hollow-stem auger/mud-rotary drill equipment. The locations of the explorations are shown on Figure 2. Details of the field exploration program, along with the exploration logs, are presented in Appendix A. Ground water conditions encountered at the time of our explorations are indicated on the individual test pit logs. The subsurface conditions observed in the test pits and test borings suggest that the entire property has surface disturbance from past grading activities, probably associated with previous coal mining activities and, to a lessor extent, agricultural purposes. The surface disturbance has resulted in one to rfour feet of fill and/or reworked topsoil mantling the property with an average thickness of about two feet. Locally, the fill is thicker, from six to ten feet thick in the vicinity of Test Pits TP-1, TP-2, TP- 6 and TP-7. Where the fill and/or reworked topsoil is from one to four feet thick,it generally consists of loose to medium dense silty sand with variable amounts of gravel and occasional fragments of coal. Where the fill this thicker (six to ten feet thick), the fill contains more coal and broken rock fragments, and is referred to as"mine rock fill"in this report. Underlying the fill and/or reworked topsoil, our explorations generally encountered weathered and unweathered Glacial Till to the completion depth of the test pits in the east portion of the site. The Glacial Till consists of medium dense to very dense silty sand with variable amounts of gravel and occasional cobbles. In the west portion of the site, the fill and/or reworked topsoil was generally underlain by weathered Glacial Till overlying Renton formation bedrock. In several explorations completed in the northwest portion of the site, fill and/or reworked topsoil was directly underlain by highly weathered bedrock(silt)and/or moderately weathered bedrock(sandstone). Icicle Creek Engineers 4 0429001/092402 Test Pits TP-16 and TP-17 were excavated within the possible wetland area identified by Talasaea in the vicinity of Lots 32, 33 and 37. It appears that in this area, based on our test pit observations, there is a two-foot thick layer of fill and reworked topsoil underlain by a thin layer of compacted soil that is causing the shallow, perched ground water conditions. The thin layer of compacted soil was likely caused by heavy equipment working in this area when the surficial fill and topsoil was reworked. Ground water seepage was encountered in the test pit explorations that were completed in March 2002 (Test Pits TP-1 through TP-11) with exception of Test Pit TP-8, TP-9 and TP-11. The ground water was encountered at depths ranging from four to seven feet at that time. No ground water was observed in the test pits completed in August 2002 (Test Pits TP-12 through TP-27), except Test Pit TP- 27 where ground water was observed at a depth of 4 feet. The test borings that were completed for the coal mine hazard ground proofing program encountered surficial (less than ten feet below the ground surface) soil and bedrock conditions that were generally consistent with the subsurface conditions observed in the test pit explorations. HISTORICAL AERIAL PHOTOGRAPH REVIEW 1936 AERIAL PHOTOGRAPH The 1936 aerial photograph (approximate scale 1 inch = 1,200 feet), shows a residence, along with driveway access and yard/orchard area, in the east portion of the property. The central and west portions are generally forested with the exception of a driveway that enters the property from the west and ends at the location for the main entry for the Springbrook No. 2 Mine. The Springbrook Mine No. 2 appears active, although no stockpiling of mine rock fill was occurring on the property at this time. Surrounding properties are generally forested and undeveloped with exception of scattered rural residential development and some mining activities associated with the nearby known coal mines. 1947 AERIAL PHOTOGRAPH The 1947 aerial photograph (approximate scale 1 inch = 1,000 feet), shows the entire ten-acre parcel to be cleared (pastureland) with what appears to be a house, garage and two outbuildings in the eastern,portion of the property. The 1947 house is at a slightly different location compared with the house in the 1936 aerial photograph. The western portion of the property is pastureland and the driveway that accessed the property from the west is not present. The main opening area for the Springbrook No. 2 Mine is pastureland, although a subtle circular feature at this location suggests that the mine had been abandoned with the mine opening backfilled. The central portion of the property appears to have been an area where mine rock fill had been stockpiled and graded out(flattened). The adjacent property to the south appears to have mining activity associated with the Springbrook-Renton Mine. Adjacent properties to the southwest, west and north are generally forested and undeveloped with scattered rural residential development. MORRISON KNUDSEN REPORT SUMMARY The previously referenced Morrison Knudsen(MK) 1985 report was conducted to inventory coal mines and subsidence features associated with these coal mines in the Renton area. The MK report indicates the presence of two elongated piles (measuring about 500 feet long and 30 feet wide) of"coal tailings" along the north and south property lines with a note that the tailings (mine rock fill) were"later removed." ABANDONED UNDERGROUND COAL MINES GENERAL Based on our review of available information referenced previously,the Springbrook No. 2 Mine underlies a portion of the Buttar property. The Springbrook No. 2 Mine was developed on the "Springbrook Coal Seam." The Springbrook Coal Seam was a commonly developed layer of coal in the Icicle Creek Engineers 5 0429001/092402 general area of the Buttar property as shown by several other "small" coal mines located on nearby properties including the Old Springbrook Mine, the Springbrook No. 1 Mine, the Renton-Springbrook Mine,the J&J Mine,the King Mine and the Hi-Grade Mine. SPRINGBROOK NO.2 MINE The Springbrook No. 2 Mine was first developed in about 1930. Three"surface entries" (a main slope and two air courses) accessed the mine in the north-central portion of the Buttar property as shown on Figure 2. The access tunnels were eventually driven underground along a coal seam that is inclined at about 61;degrees below horizontal. Based on our review of the historic mine maps,the depth of the mine beneath the Buttar property ranges from about 40 to 250 feet below the ground surface. The location of the Springbrook No. 2 Mine is shown on Figure 2. The underground orientation of the Springbrook No. 2 Mine is shown on the Geologic Cross-Sections A-A',B-B', C-C' and D-D',Figures 3 through 6. The thickness of coal extracted was about six feet. The extraction ratio was reportedly very high and is estimated at 80 to 100 percent based on review of the detailed underground map of the Springbrook No. 2 Mine. According to the historic mine maps, the Springbrook No. 2 Mine was abandoned in about 1940. MINING METHODS The underground coal mines in the Buttar property area were developed using"room-and-pillar" mining methods. Initial development of the mines was from a "main slope" or entry driven down or parallel to the slope of the coal seam. The main slope is usually paired with a second slope driven parallel to the main slope to provide air circulation. The main slope and air course were connected at certain intervals with cross-cutting tunnels. Air would then be mechanically pulled (using a fan) out of the air course resulting in fresh air being drawn down the main slope to provide ventilation in the mine. Usually the main slope and air course were heavily shored with timber posts and beams to prevent collapse. The main slope was used to remove coal from the mine using coal cars on tracks that were lifted up the main slope using a hoist. At a certain depth, a main haulageway(a wide,main entry tunnel)was driven at a near horizontal line along the coal seam to facilitate drainage. The main haulageway served as the primary entry to the production areas of the mine. At specified intervals along the main haulageway, "chutes" were driven up the coal seam to a "chain pillar." The chain pillar is coal left in place to protect the upper haulageway from caving into the next level below. Occasionally, a chute would extend further up to gain access to a new level where a secondary haulageway would be extended along the strike of the coal seam. "Cross-cuts" were then driven between the chutes. The chutes and cross-cuts were then widened until the coal left in place (pillars) and rooms comprised about a 1 to 1 ratio. Most or all of the pillars were removed before abandonment of a level. This mining method is referred to as "full pillar extraction." Full pillar extraction is a normal underground mining process designed to maximize coal extraction and to promote short term collapse of the mined-out areas. As designed,the removal of the pillars typically causes the mined-out area to collapse within a few days to a few weeks following retreat since backfilling was not intended. Based on engineering studies conducted at the time of mining, caving of the mined-out areas (rooms) was desirable upon retreat of production areas. Room caving was desired to allow the overburden pressures in the mines to adjust. If mined-out rooms remained open,then "bumps"became a major concern. Bumps occur when a large room remains open for a long period of time followed by a catastrophic collapse sending an air blast through the mine that could injure the miners. UNDOCUMENTED MINING The Springbrook mines in the vicinity of the Buttar property are in an area where undocumented mining occurred. The primary reason for this was that some of these mines were operated in the 1940s Icicle Creek Engineers 6 0429001/092402 and 1950s when the value of coal was low and documentation of mine workings was deemed unnecessary because of cost. Based on our information review, including review of historical aerial photographs and mine maps,no suspect undocumented mining activities are known within the Buttar property. GROUND PROOFING PROGRAM SUMMARY The ground proofing program was conducted by drilling thirteen, six-inch-diameter borings (Borings B-1 through B-13) at the approximate locations shown on Figure 2. The number and spacing of the borings was determined such that the probability of drilling through"support pillars"was reduced to a low level and to increase the confidence in mine map accuracy. Based on the results of Borings B-1 through B-13, no evidence (such as subsurface voids, mine timbers,�circulation loss during drilling) of"open"mine workings were observed. Several of the borings encountered "soft drilling" indicating caved rock or open fractures less than one inch wide. The Springbrook No. 2 Mine appears to be collapsed based on the results of the test boring explorations. The results of the Borings B-1 through B-13 suggest that the accuracy of the historic mine maps is excellent. We generally encountered the coal seam or mine zone associated with the Springbrook No. 2 Mine within five feet of its expected location. Geologic cross-sections showing our interpretation of subsurface conditions are shown on Figures 3 through 6. The following is a brief summary of each boring. Boring B-1: Boring B-1 encountered bedrock at a depth of one foot. Soft drilling was encountered in the bedrock at a depth of 12.5 to 12.6 feet. Boring B-2: Boring B-2 encountered bedrock at a depth of one foot. Soft drilling was encountered in the bedrock at a depth of 11 to 11.1 feet and 32 to 32.1 feet. Boring B-3: Boring B-3 encountered bedrock at a depth of 13 feet. Soft drilling was encountered in the bedrock at a depth of 22 to 22.1 feet. Boring B-4: Boring B-4 encountered bedrock at a depth of 18 feet. Soft drilling was encountered in the bedrock at a depth of 69 to 74 feet. Boring B-5: Boring B-5 encountered bedrock at a depth of 22.5 feet. A fracture in the bedrock was encountered at a depth of 29 feet,based on a loss of drilling fluid. Boring B-6: Boring B-6 encountered bedrock at a depth of 23 feet. No soft drilling or fractures were encountered in the bedrock. Boring B-7: Boring B-7 encountered bedrock at a depth of 22 feet. Soft drilling was encountered in the bedrock at a depth of 69 to 69.5 feet. Boring B-8: Boring B-8 encountered bedrock at a depth of 13 feet. No soft drilling or fractures were encountered in the bedrock. Boring B-9: Boring B-9 encountered bedrock at a depth of 17 feet. A series of bedrock fractures was encountered in the bedrock at a depth of 35 to 45 feet,based on a loss of drilling fluid. Boring B-10: Boring B-10 encountered bedrock at a depth of 13 feet. No soft drilling or fractures were encountered in the bedrock. Boring B-11: Boring B-11 encountered bedrock at a depth of seven feet. A fracture in the bedrock was encountered at a depth of 39 feet, based on a loss of drilling fluid. Soft drilling was encountered in the bedrock at a depth of 69 to 69.3 feet. ' Boring B-12: Boring B-12 encountered bedrock at a depth of nine feet. A fracture in the bedrock was encountered at a depth of 36 feet, based on a loss of drilling fluid. Soft drilling was encountered in the bedrock at a depth of 57 to 58 feet, 62 to 63 feet and 68 to 69 feet. Boring B-13: Boring B-13 encountered bedrock at a depth of 14 feet. No soft drilling or fractures were encountered in the bedrock. Icicle Creek Engineers 7 0429001/092402 GENERAL DESCRIPTION OF HAZARDS ASSOCIATED WITH COAL MINES The principal physical hazards associated with abandoned coal mines include the following: • Sinkholes(High Coal Mine Hazard Areas) • Regional ground subsidence(Medium Coal Mine Hazard Areas) • Non-affected areas (Low Coal Mine Hazard Areas) The Renton Municipal Code Title IV Development Regulations defines coal mine hazards as follows: High Coal Mine Hazard - Areas with abandoned and improperly sealed mine openings and areas underlain by mine workings shallower than two hundred feet (200) in depth for steeply dipping seams, or shallower than fifteen (15) times the thickness of the seam or workings for gently dipping seams. These areas may be affected by collapse or other subsidence. Medium Coal Mine Hazards—Areas where the mine workings are deeper than two hundred feet(200) for steeply dipping seams, or deeper than fifteen (15) times the thickness of the seam for gently dipping seams. These areas may be affected by subsidence. Low Coal Mine Hazards—Areas with no known mine workings and no predicted subsidence. While no mines are known in these areas, undocumented mining is known to have occurred. ANALYSIS OF COAL MINE HAZARDS HIGH COAL MINE HAZARD AREAS The Springbrook No. 2 Mine was fully collapsed in all explorations that penetrated the abandoned underground mine. For this reason, no open mine workings are expected at depths of less than 200 feet. However, three backfilled mine openings exist in the north central portion of the Buttar property as shown on Figure 2. We recommend that the area of the three backfilled mine openings be classified as a High Coal Mine Hazard Area as shown on the Coal Mine Hazards Map, Figure 7. The J& J Mine, the King Mine and the Hi-Grade Mine which are located north of the Buttar property were not evaluated in detail for this study. However, these abandoned underground mines exist in an area where an alternative access road to the project may be considered. The general area of these off-site mines should be considered a High Coal Mine Hazard Area until a detailed coal mine hazard assessment is completed in this area. MEDIUM COAL MINE HAZARD AREAS The Springbrook No. 2 Mine was fully collapsed in all explorations that penetrated the shallow (less than 200 feet deep) abandoned underground mine. The deeper mine workings are expected to also be collapsed. Based on the results of our ground proofing program, the Springbrook No. 2 Mine is collapsed and therefore this area should be treated as if no underground mining occurred outside of the Severe Coal Mine Hazard area. No Medium Coal Mine Hazards exist within the Buttar property. LOW COAL MINE HAZARD AREAS 'No known undocumented coal mining occurred within the Buttar property based on review of historical mine maps and historical aerial photographs and anecdotal reports. No Low Coal Mine Hazards exist within the Buttar property. CONCLUSIONS AND RECOMMENDATIONS COAL MINE HAZARDS General Based on our review of available information, site observations, ground proofing and analysis of coal mine hazards at the Buttar property, we have developed the following conclusions: • A portion of the Buttar property is underlain by the Springbrook No. 2 Mine as shown on Figure 2. Icicle' Creek Engineers 8 0429001/092402 • The Springbrook No. 2 Mine dips at very steep angle (approximately 61 degrees) down to the south as shown on Figures 3 through 6. • Three backfilled mine openings for the Springbrook No. 2 Mine occur in the north-central portion of the Buttar property as shown on Figure 2. It is likely that engineered backfill was not conducted to cover these mine openings. • The abandoned J & J Mine, the King Mine and the Hi-Grade Mine are located north of the Buttar property. • Based on the results of the ground proofing program we conclude that the Springbrook No. 2 Mine is substantially collapsed. • No manifestation of regional ground subsidence was observed, such as linear sags in the ground surface parallel to the underground mine workings, during our geologic reconnaissance. • High Coal Mine Hazards exist in the north-central portion of the Buttar property where three backfilled mine openings exist as shown on Figure 7. Also, a High Coal Mine Hazard area associated with the off-site J & J Mine, the King Mine and the Hi-Grade Mine exists north of the Buttar property as shown on Figure 7. • No Medium Coal Mine Hazard Areas were identified within the Buttar property because the mine workings are collapsed based on the results of the subsurface explorations. • No ,Low Coal Mine Hazard Areas were identified within the Buttar property because the mine workings are collapsed based on the results of the subsurface explorations, there is no predicted ground subsidence and there is no known undocumented mining. • Mine rock fill up to ten feet thick occurs across the central and northwest portion of the Buttar property as shown on Figures 2 and 7. The fill may be thicker in local areas, but was not penetrated in the test pit explorations. Other areas of mine rock fill may exist outside of the fill area shown on Figures 2 and 7. • Mine rock fill containing more than 20 percent by weight unoxidized coal should not be used for foundation support of buildings. If building development in these areas is desired, then the mine rock fill should be removed from the building development area. Mitigation No building structures, stormwater detention facilities, roads or utilities should be allowed in High Coal Mine Hazard Areas. High Coal Mine Hazard areas should remain as open space. Mine Rock Fill Mine rock fill occurs within the Buttar property as shown on Figures 2 and 7. Some of this mine rock fill contains unoxidized coal (coal fines). Mine rock fill containing more than 20 percent by weight unoxidzed coal should be mixed with other inorganic soils, left in place as open space areas or removed from the site. The mine rock fill may be used for structural fill provided the unoxidized carbon content is low (less than 20 percent coal by weight). Combining the mine rock fill with inorganic soil may also be used to prepare this material for use as structural fill if the coal content is high. As with any fill material, the moisture content of the mine rock fill may need to be adjusted to achieve adequate compaction. Mine rock fill may also be used in landscape areas. GEOTECHNICAL ENGINEERING EVALUATION Genefal It is our opinion that the Buttar property can be developed satisfactorily if recommendations included herein are carried out. Generally, conventional design and construction practices will be appropriate. The native soils or bedrock underlying the loose fill and/or topsoil, should provide excellent support for buildings and roadways. Mine rock fill locally occurs on the site as shown on Figure 2. Mine rock fill containing more than 20 percent unoxidized coal by weight will air-degrade over time Icicle Creek Engineers 9 0429001/092402 causing settlement, and is therefore not suitable as structural fill. The mine rock fill is in a very loose condition and may contain appreciable amount of organic material(roots)and may not be suitable for use as structural fill. Excavation of the glacial till and bedrock, if required, will require large excavation equipment (such as a Caterpillar 235). The glacial till and bedrock that underlies the property limits vertical infiltration of water. For this reason, drainage of subgrade walls will require special design considerations to prevent ground water from entering below-grade facilities. A significant geotechnical aspect regarding project costs is related to project schedule. Construction costs will be higher if extended periods of wet weather occur during project earthwork activities. All components of the project involve soils that have a fines content such that it will be difficult, if not impossible, to properly compact during wet periods. Also, trafficability of heavy construction equipment will be difficult, or impossible if the site soils become wet. Site Preparation and General Earthwork We recommend that only the building sites and roadways be stripped of vegetation and significant organic material (primarily sod) and topsoil. We expect that the stripping depths will be variable'and range from one to two feet in order to remove the sod, topsoil and significant surficial root zone. Greater depths will be necessary in areas with thick vegetation and trees. This material should be wasted off-site or used for landscaping purposes. As mentioned previously, the site soils contain a high fines content and are very moisture sensitive and difficult or impossible to operate on and to compact during wet weather. Rubber-tired vehicles and even foot traffic will disturb this material when it is above-optimum moisture. This material readily absorbs moisture and drying it out is difficult. This material also has a high erosion potential and silt fences and other measures will be necessary to control erosion,and sediment transport during construction. The sod layer acts as a protective layer to this surficial silty sand and should be removed only where and when necessary. We recommend that the mine rock fill containing more than 20 percent coal by weight be removed from areas where development or filling is planned. Mine rock fill could be reused as structural fill provided that it is moisture conditioned for proper compaction, and that the coal content is low as previously described. Depending on the grading plans, certain areas of the property may be backfilled. If these areas are to be used to support structures, then site preparation should include stripping all organic material, topsoil'and mine rock or soil fill before placing structural fill. Excavations Excavation of the glacial till and bedrock will require large excavation equipment (such as a Caterpillar 235). It is possible that zones of well-cemented bedrock, although not encountered in our test pit explorations, may be encountered that require blasting to loosen. The walls of excavations .within Glacial Till or Renton formation bedrock, including utility trench walls, may be cut vertical to a depth of about four feet. Excavations greater than four feet in depth generally will be self-supporting for short periods of time at inclinations of 0.5H:l V (horizontal to vertical) or shored to depths of six to eight feet. Temporary cut-slope inclinations for the trench excavations should be made in accordance with applicable OSHA and WISHA regulations. The shoring system, if used,must comply with the provisions of Title 296 WAC, Part N, "Excavation, Trenching and Shoring." The earthwork contractor should be responsible for the design and installation of shoring systems. Structural Fill General: All new fill for buildings and roadways should be placed as compacted structural fill. Structural fill should be free of debris, organic contaminants and rock fragments larger than six inches. The suitability of soil for use as structural fill will depend on its gradation (grain-size distribution) and Icicle Creek Engineers 10 0429001/092402 1 ' moisture content. As the amount of fines (portion passing a U.S. Standard No. 200 sieve) increases, soil becomes increasingly sensitive to small changes in moisture content and adequate compaction becomes more difficult or impossible to achieve. Imported Unclassified Fill: We recommend that imported unclassified fill consist primarily of granular material with less than 30 percent passing the U.S. Standard No. 200 sieve. Unclassified material will be sensitive to changes in moisture content and compaction may be difficult or impossible to achieve during wet weather. We recommend that unclassified material be used as structural fill only during dry weather conditions when proper moisture conditioning can be achieved. Imported Gravel Borrow: We recommend that gravel borrow conform with Section 9-03.14 (Select Borrow) of the 2000 WSDOT Standard Specifications for Road, Bridge, and Municipal Construction. We recommend that structural fill consist of gravel borrow during wet weather and in wet subgrade conditions. Subbase and Drainage Layer: We recommend that subbase material for the pavement section and the ,drainage layer described subsequently consist of gravel borrow as described above with the further restriction that the gravel borrow contain no more than five percent fines (based on the fraction of 3/4-inch-minus material passing the U.S. Standard No. 200 sieve). Use of On-Site Soil and Bedrock Material: The on-site soils and bedrock are highly sensitive to small,changes in moisture content. We recommend that the on-site soils and bedrock be used for structural fill only during extended periods of dry weather. Mine rock fill locally occurs in two areas on the site as shown on Figure 2. This material may not be suitable for reuse as structural fill because of the presence of large amounts of coal fines and other organic matter. The north area of mine rock fill may be planned as open space so this material could be left in place. The south area of mine rock fill occurs in an area planned for development. We estimate that there is approximately 5,000 cubic yards of unsuitable fill in this south area. However, as the grading of this area progresses, it is possible that some of this material could be reused as structural fill to be determined in the field. Compaction equipment that is suited for fine-grained soils, such as a sheepsfoot roller, may be necessary if the excavated bedrock is used for fill. We expect that bedrock excavated from the cut areas will consist of a mixture of soil-size particles (broken-up fragments of weathered bedrock) to larger particles of slightly weathered bedrock. We recommend that all rock particles used for structural fill be twelve inches or less in size. Where the majority of particles of excavated rock are three inches or larger, the rock should be blended with a sufficient amount of soil containing particles that are three inches or less in size to eliminate the presence of large voids in the structural fill after placement. Placement and Compaction: All fill necessary in buildings and roadways and on slopes must be placed as compacted structural fill. Structural fill should be placed in horizontal lifts not exceeding ten inches in loose thickness and each lift must be conditioned to the proper moisture content and then uniformly compacted. All fill placed in building areas and within two feet of the finished subgrade in roadways must be compacted to at least 95 percent of the maximum dry density(MDD) as determined by the ASTM D-1557 test procedure. Fill placed in roadways at depths greater than two feet below the finished subgrade and at other locations should be compacted to at least 90 percent of the MDD. Fill placed on slopes steeper than 4H:1 V (horizontal to vertical) should be benched or keyed into dense native soils. We recommend permanent structural fill slopes be no steeper than 2H:1 V. The compaction equipment should be run over the edge of the fill to provide good compaction or the fill can be overbuilt by several feet and cut back to the required slope. Hydroseeding or other erosion protection should be applied immediately after final grades are achieved. ,We recommend that a representative from our firm observe the preparation for, placement, and compaction of structural fill. An adequate number of in-place density tests should be performed in the fill to evaluate if the desired degree of compaction is being achieved. Icicle Creek Engineers 11 0429001/092402 Cut and Fill Slopes Cut Slopes in Soil: We recommend that permanent cut slopes in soil be inclined no steeper than 2H:1 V. This inclination assumes that adequate drainage facilities on cut slopes are installed prior to and during the grading activities. Cut Slopes in Rock: The shallow bedrock is generally highly to moderately weathered and susceptible to degradation from weathering. Under these circumstances, we suggest that the rock slopes be inclined at 1.5H:1 V to minimize maintenance. All loose material should be removed from the rock face after the cut slopes are accomplished. It may be possible to steepen the slope inclinations once some of the rock has been exposed and the degree of weathering and other discontinuities in the bedrock can be examined in the exposure. The soil cuts above the bedrock should be inclined as recommended in the previous section. Some raveling and weathering of the exposed bedrock may occur. We recommend that a suitable ditch be provided for catchment of debris; we suggest a five-foot minimum width. Fill Slopes: We recommend that all fill embankments be constructed with structural fill which is placed and compacted as described in the "Placement and Compaction" section. In general, we recommend that fill embankments compacted to at least 90 percent of the MDD be sloped no steeper than 2H:1V. It may be possible to incline fill slopes as steep as 1.5H:1 V where the structural fill consists of gravel borrow. However, some raveling of the surface of these steeper slopes is likely to occur that will require periodic maintenance. Temporary Cut Slopes: Where temporary cut slopes are required, we recommend that slopes be inclined no steeper than 1H:1V for planning purposes. These slopes should be flattened as necessary where seepage is present on the cut face. It should be expected that the cut face will experience some sloughing and raveling. Plastic sheeting may be necessary to protect the slopes from erosion and raveling in wet weather. We recommend that temporary excavations, including any temporary shoring, be made the responsibility of the contractor. The contractor is present at the site continuously and is best able to observe changes in site and soil conditions and monitor the performance of excavations. All shoring and temporary slopes should conform to applicable local, state and federal safety regulations. Erosion Protection: Cut slopes in soil and bedrock, and fill slopes in soil will be subject to erosion until a vegetative cover is established. We recommend that all cut and fill soil slopes be hydroseeded as soon as possible. It may be necessary to install temporary erosion protection until the permanent vegetative cover has established itself. Fill Settlements Fill will experience settlements which will be a function of the thickness of the fill materials and underlying native soils. We expect that the following settlements of new fill may be experienced as a function of new fill thickness: Fill Thickness Estimated Fill Settlement (feet) (inches) 10 20 %z- 3/a 25 % - 1 Approximately 70 to 90 percent of these settlements are expected to occur within eight weeks after placement of the fill, with the remainder occurring over an extended period of time. The estimated time of settlement to occur is approximate and will depend on the thickness of loose or medium dense soil underlying the fill, embankment construction progress and other factors. We do not expect that significant differential settlements will occur along fill embankments assuming that the fill embankments are not constructed over any localized thicknesses of organic and/or soft subgrade soils. Icicle,Creek Engineers 12 0429001/092402 Spread Footings Conventional shallow spread footing design may be used for building support. We recommend the footings bear upon structural fill, glacial till, or the bedrock at least 18 inches below the lowest adjacent finished grade. The footings should not be founded on existing fill soils. If necessary, they could be founded on compacted structural fill which should extend, horizontally beyond the edge of the footings at least twelve inches and continue at a maximum 1 H:1 V slope to suitable bearing strata. We recommend a maximum allowable soil bearing pressure of 2,500 pounds per square foot (psf) for support on structural fill or glacial till. We recommend a maximum allowable soil bearing pressure of 4,000 psf for support on the moderately to slightly weathered bedrock. These values include dead plus long-term live loads. All continuous footings should have a minimum width of 16 inches, while isolated column footings should have a minimum width of 24 inches. This allowable soil bearing pressure may be increased by up to one-third to accommodate wind or seismic loads. The weight of the footing and any backfill over the footing may be neglected. We estimate that the total settlement of footings founded according to our recommendations may be about Y2 inch with less than half the total as differential settlement provided footings are founded on similar bearing conditions. However, existing fill soils or disturbed soils not removed from footing excavations before pouring concrete will probably result in increased settlement. It should be noted that the footing subgrades will be susceptible to disturbance when wet. It may be necessary to pour a lean concrete "mud mat" or place a layer of rock on the exposed soil in the excavations for the footings to protect the footing subgrade from water and/or wet weather during reinforcement bar placement or construction of forms. We recommend that the condition of all footing excavations be observed by a representative from our firm before placement of concrete to confirm that the bearing soils are undisturbed and are consistent with the recommendations contained within this report. All disturbed or softened fill or native soil must be removed and replaced with concrete or structural fill. Floor Slab Support The floor slab subgrade should be evaluated per the recommended site preparation procedures. We recommend that the capillary break consist of a minimum four-inch thickness of crushed rock or well-graded sand and gravel compacted to at least 95 percent of the MDD. The capillary break material should have a maximum particle size of 3/4-inch, with not more than 80 percent passing the U.S. Standard No. 4 sieve and less than five percent fines. A vapor barrier such as plastic sheeting between the floor slab and the capillary break can be used to provide an added protection against upward migration of moisture into the slab. Also, a two-inch thick layer of sand can be placed over the vapor barrier to protect the vapor barrier from damage during floor slab construction and to aid in uniform curing of the concrete,if desirable. Subgrade Walls Subgrade walls may be designed for a static lateral soil pressure determined using an equivalent fluid weight of 35 pounds per cubic foot (pcf), provided the backfill is placed and compacted as recommended below and the backfill is drained. This soil pressure assumes that the walls are allowed to yield slightly during placement of backfill. The subgrade walls should be backfilled with free-draining sand and gravel and must include a footing drain to eliminate the potential for the buildup of hydrostatic pressures on the walls and moisture beneath the floor slab and/or next to subgrade walls. Any ground water that may infiltrate into the permeable wall backfill may become trapped and cause wet floors and/or walls. The footing drain should consist of four-inch diameter perforated, rigid, smooth-walled PVC pipe or corrugated metal culvert placed on a bed of,and surrounded by, free draining sand and gravel. Icicle Creek Engineers 13 0429001/092402 g Lateral Resistance Lateral loads on footings may be resisted by passive resistance on the sides of the footings and by friction on the base of the footings and slab. Passive resistance should be evaluated using an equivalent fluid density of 300 pcf, where footing faces are poured neat in contact with undisturbed native,soil or bedrock or are surrounded by structural fill compacted to at least 95 percent of MDD as recommended. Structural fill should extend laterally a minimum width of at least twice the footing depth. Resistance to passive pressure should be calculated from the bottom of adjacent floor slabs and paving or below a depth of one foot where the adjacent area is unpaved, as appropriate. Frictional resistance can be evaluated using 0.4 for the coefficient of base friction against footings and the building slab. The above values incorporate a factor of safety of about 1.5. Utilities Based on our explorations, most of the utilities less than ten feet deep (from the original ground surface) will be embedded in native soil or bedrock such that excavation with standard construction equipment will be possible. There are some exceptions especially where deep cuts (more than ten feet) are expected into the bedrock. We expect that utility excavation deeper than about ten feet below the original ground surface will require heavy-duty excavation equipment with rippers (such as a Caterpillar 235 excavator or equivalent) or rock splitting capability to achieve an acceptable rate of advancement. In our opinion, normal bedding requirements should be satisfactory. Utility backfill in the roadway or in other settlement-sensitive areas should be compacted to 90 percent of the MDD except for the upper two feet which should be compacted to 95 percent of the MDD. Where utilities are bedded and/or backfilled with free-draining pea gravel, sand or gravel, and where the utility trench slopes more than five percent, we recommend that backfill "check dams" be constructed to prevent movement of ground water through the bedding or backfill material. These dams consist of relatively impermeable soil extending from the base of the trench, surrounding the pipe and extending to the surface to impede movement of ground water. Trench dams are typically spaced 30 to 100 feet apart. Steep utility trench grades (i.e., more than eight to ten percent) would probably require the minimum spacing. Pavements Pavement subgrade areas should be evaluated and prepared as recommended previously in this report. We recommend that the upper two feet of subgrade be compacted to at least 95 percent of the MDD. The pavement section (crushed rock base and asphalt concrete) should be designed according to City of Renton standards. If the subgrade soils are soft, it may be necessary to excavate the soft soils,place a subbase layer, and/or a suitable geotextile fabric such as Mirafi 500X or other as approved by the geotechnical engineer. In that case, we expect that a minimum subbase thickness of at least nine inches will be necessary, although a greater thickness may be required during wet weather and poor subgrade conditions. The subbase should consist of well-graded sand and gravel with a maximum particle size of PA inches and less than five percent fines. Where site grades are raised using structural fill that meets the subbase specifications,the structural fill may be considered the subbase. It is critical to pavement performance that backfill in utility line trenches be compacted to structural fill specifications. Trench backfill within two feet below pavement subgrade elevations should be compacted to at least 95 percent of the MDD. Trench backfill more than two feet below pavement subgrade elevations should be compacted to at least 90 percent of the same standard. Icicle Creek Engineers 14 0429001/092402 EROSION CONTROL AND DRAINAGE MEASURES General Some soils are particularly susceptible to erosion because of particle gradation or density. In our opinion, all of the near-surface soils at the project site have a moderate to high erosion potential where exposed on slopes. Temporary Erosion Control The most effective methods of erosion control on construction sites include efficient surface water management, minimization of disturbed areas, erosion preventative slope covers, channel liners and energy dissipaters for trenches, and diversion ditches or levees. Temporary erosion control measures should include proper control of surface water runoff, use of straw bale or appropriate geotextile filters and temporary sedimentation basins. New cut and fill slopes must be protected during wet weather to minimize slope erosion. Temporary protection could consist of plastic or membrane covers, or seeding combined with placement of a straw mulch. If straw mulch is used for temporary protection, we recommend a minimum of two inches loose thickness. Erosion control programs should comply with local requirements and guidelines. Permanent Erosion Control All grading should be accomplished to avoid concentration of runoff onto or off of unprotected cut or fill slopes, roadways, or natural slopes. Interceptor ditches or drains may be necessary to collect and divert flow from seepage zones. The need for interceptor ditches or drains can best be evaluated during construction. We recommend that drainage ditches or swales be constructed along the toe of permanent cuts to control slope runoff onto roadways. Open ditches or swales should be sloped less than five percent or • should be lined with rock spalls or other suitable material to prevent erosion. Flow in ditches and swales should be routed to cross-culverts or into the stormwater collection system. All paved areas must be graded to prevent pavement runoff from flowing down adjacent slopes. We recommend that new cut and fill slopes and other areas where the vegetative cover has been removed be planted or seeded as soon as possible. Permanent Drainage Measures General: Much of the site is underlain by relatively impermeable soils and bedrock. These materials tend to prevent the downward infiltration of precipitation, and therefore create "perched" ground water conditions. It is very important that appropriate permanent drainage measures be provided for the project. In our opinion, subsurface drainage measures should consist of a combination of footing drains and French drains. Footing Drains: Footing drains should be provided for the exterior footings of the buildings. These drains should consist of a four-inch-diameter rigid, perforated, smooth-walled PVC pipe installed at the outside base of the perimeter footing. The perforated drainpipe should be embedded in a zone of coarse sand and gravel containing less than three percent fines. The sand and gravel should be encapsulated in nonwoven filter fabric such as Mirafi 140N, or equal. At appropriate intervals such that water backup does not occur, the drainpipe should be connected to a tightline system leading to a suitable discharge. French Drains: A system of French drains may be designed and installed in landscaped areas to provide drainage. The French drain trenches should be at least 24 inches wide. Where possible, the trenches should penetrate through the upper pervious soils and extend into the relatively impervious unweathered glacial till. The French drain trench should be lined with nonwoven filter fabric such as Mirafi 140N, or equal. It is important that the filter fabric not be placed in a muddy trench to avoid filling the pore spaces with mud and plugging the fabric. Icicle Creek Engineers 15 0429001/092402 All French drains should be composed of a zone of clean free-draining coarse sand and gravel containing less than three percent fines. Smooth-walled perforated drainpipe having a minimum diameter of four inches should be embedded within this zone of coarse sand and gravel. The drainpipe should be installed with the perforations"down"and should be sloped to drain. At appropriate intervals, the perforated drainpipe should be connected to a tightline leading to the stormwater disposal system for the site. Cleanouts should be installed at appropriate intervals. French drains should not be connected to footing drains. POSSIBLE WETLAND(in the vicinity of Lots 32,33 and 37) Based on our knowledge of site history, site observations and test pit explorations, it appears that the "wetland" conditions in the vicinity of Lots 32, 33 and 37 have been created by past site grading activities. These grading activities appear to have compacted a thin layer of fill with heavy equipment traffic near the contact with the underlying native soils. The material overlying the thin compacted layer consists of loose fill and reworked topsoil. In our opinion, this condition of the thin layer of compacted soil overlain by less dense and more permeable soil causes shallow ground water to concentrate in this area during the wet season. USE OF THIS REPORT We have prepared this report for use by Baljinder Buttar and his associates and engineers for their use in planning of this project. The data and report should be provided to prospective contractors for their bidding or estimating purposes, but our report, conclusions and interpretations should not be construed as a warranty of subsurface conditions. The scope of our services does not include services related to construction safety precautions and our recommendations are not intended to direct the contractor's methods, techniques, sequences or procedures, except as specifically described in our report for consideration in design. If there are significant changes in the grades, configurations or types of facilities to be constructed, the conclusions and recommendations presented in this report may not be fully applicable. When the design has been fmalized, we recommend that we be retained to review those portions of the specifications and drawings which relate to geotechnical considerations to see that our recommendations have been interpreted and implemented as intended. There are probable variations in subsurface conditions between the explorations and also that may occur with time. A contingency for unanticipated conditions should be included in the budget and schedule. Sufficient monitoring, testing and consultation by our firm should be provided during construction to confirm that the conditions encountered are, consistent with those indicated by the explorations, to provide recommendations for design changes if the conditions revealed during construction differ from those anticipated, and to evaluate whether earthwork and foundation installation activities comply with contract plans and specifications. Within the limitations of scope, schedule and budget, our services have been executed in accordance with generally accepted practices in this area at the time the report was prepared. No warranty or other conditions, express or implied, should be understood. Icicle Creek Engineers 16 0429001/092402 We trust this information meets your present needs.

The test pits were excavated on March 28,2002 and August 23, 2002 using a PC-120 track-mounted excavator owned and operated by Nelson & Sons Construction, Inc. of Redmond, Washington. The test borings were drilled between April 1 and 10, 2002 using hollow-stem/mud-rotary drill equipment owned and operated by Gregory Drilling, Inc. of Redmond, Washington. The-test pits were located in the field by measuring from known surface features. The test borings were field surveyed for location and elevation by Core Design, Inc. following the drilling. The locations of the explorations are shown on Figure 2. The explorations were continuously monitored by an engineering geologist or geotechnical engineer from ICE who classified the soils or bedrock encountered, obtained representative soil and bedrock samples, observed ground water conditions and prepared a detailed log of each exploration. The soil consistencies noted on the exploration logs are based on the conditions observed, our experience and judgement, and blow count data (Borings B-1 and B-2) obtained during drilling. Representative samples were obtained at 5-foot depth intervals using a 1.5-inch diameter split-spoon standard penetration test (SPT) sampler for Borings B-1 and B-2. The sampler was driven 18 inches, if possible, 140-pound weight falling a vertical distance of approximately 30 inches. The number of blows required to drive the sampler the last 12 inches, or other indicated distance, is recorded on the boring logs. It should be noted that the blow counts may not be representative (will be overstated) of the formation density when gravel or cobbles are encountered. Representative samples were obtained at five-foot intervals by screening soil cuttings from the discharge pipe for Borings B-3 through B-13. In some zones, no soil samples were obtained because of loss of drill circulation. However, the drilling rate was monitored for relative bedrock hardness, soft drilling and voids when loss of drill circulation was encountered. Soils encountered were classified in general accordance with the classification system described in Figure A-1. Bedrock was classified using standard geological methods. The boring logs are presented in Figures A-2 through A-14. The test pit logs are presented in Figure A-15. The exploration logs are based on our interpretation of the field data and indicate the various types of soil and bedrock encountered. They also indicate the depths at which these soil and rock types or their characteristics change, although the change might actually be gradual. If the change occurred between samples in the borings, it was interpreted. Ground water conditions were observed as the test pits were excavated and are noted on the test pit logs. Ground water was not monitored in the borings because the drilling method generally used introduced water for circulation Icicle Creek Engineers A-1 0429001/092402 Unified Soil Classification System Soil Classification and MAJOR DIVISIONS Generalized Group Soil Particle Size Definitions Description Component Size Range Coarse- GRAVEL GW Well-graded gravels CLEAN GRAVEL Boulders Coarser than 12 inch Grained More than 50% GP Poorly-graded gravels Cobbles 3 inch to 12 inch Soils of coarse fraction retained on the GRAVEL WITH GM Gravel and silt mixtures Gravel 3 inch to No.4(4.78 mm) FINES Gravel and claymixtures Coarse 3 inch to 3/4 inch No.4 sieve GC Fine 3/4 inch to No.4(4.78 mm) SAND SW Well-graded sand Sand No.4(4.78 mm)to No.200 CLEAN SAND SP Poorly-graded sand (0.074mm) More than 50% Coarse No.4(4.78 mm)to No. 10 ' More than 50% of coarse fraction SAND WITH SM Sand and silt mixtures (2.0 mm) retained on the passes the FINES Medium No. 10(2.0 mm)to No.40 No.200 sieve No.4 sieve SC Sand and clay mixtures (0.42 mm) Fine SILT AND CLAY ML Low-plasticity silts Fine No.40(0.42 mm)to No.200 Grained INORGANIC (0.074 mm) CL Low-plasticity clays Soils Silt and Clay Finer than No.200(0.074 mm) Liquid Limit ORGANIC OL Low plasicity organic silts less than 50 and organic clays SILT AND CLAY MH High-plasticity silts INORGANIC More than 50% CH High-plasticity clays passing the Liquid Limit ORGANIC OH High-plasticity organic silts No.200 sieve greater than 50 and organic clays - Highly Organic Soils Primarily organic matter with organic odor PT Peat Notes:I) Soil classification based on visual classification of soil is based on ASTM D2488-90.

The proposed Buttar Residential Plat is a 10-acre residential development located between Talbot Road and Mill Avenue SE, north of Carr Road SE on Renton's southeast hill; the site is adjacent to the north side of the Sunnybrook Plat. Upon completion and expected occupancy in 2005, the proposed development would consist of up to 50 single-family residential units. The existing site is currently vacant. Trip Generation. The 50-lot single-family residential development is estimated to generate 500 average weekday daily vehicle trips, of which 38 (9 entering, 29 exiting) would occur during the weekday AM peak hour, and 51 (33 entering, 18 exiting) during the weekday PM peak hour. Vehicular Site Access. Vehicular access to/from the site is proposed at two y locations: one on the east via a new connection via the Cedar Avenue S alignment and intersection with SE 172nd Street, and one on the south side of the site through a future connection with the approved Sunnybrook Plat. A future connection to the undeveloped property to the north is also anticipated. All turning movements ,,- at the driveways are expected to operate at LOS A or better during both weekday AM and PM peak hours upon completion of the proposed project. Short-Term Proportional Impacts. No significant impacts were identified at any of the study intersections based on City Guidelines. Therefore, the installation of site-specific improvements under SEPA is not required. Long-Term Impacts. The long-term mitigation required by the City of Renton is payment of a $75 traffic impact fee based on the estimated number of new daily trips the development generates. The proposed Buttar Residential Plat is - estimated to generate about 500 average daily trips. Future Development Connections. The on-site roadway system and proposed 111 site access driveways are designed such that future development of the properties to the north have the ability to connect into the street system in a continuous and uninterrupted manner. Conclusion. Based on the information included in this report, the proposed Buttar Residential Plat would have no significant adverse impacts on adjacent streets, study area intersections, or non-motorized facilities. Two access points are proposed to serve residents and emergency vehicles. Payment of the traffic impact fee would mitigate long-term impacts. -' r Transportation Engineering Northwest 1 October 3,2002 1 • r Buttar Residential Plat—City of Renton,WA Traffic Impact Study INTRODUCTION Project Approach This traffic impact analysis (TIA) has been prepared for the proposed Buttar Residential Plat residential development. The site is generally located east of Talbot Road,west of Mill Road, and north of Carr Road in the City of Renton(see Figure 1). The property is adjacent to the north side of the Sunnybrook Plat project. The proposed project includes 50 single-family residential lots. The existing site is vacant. Vehicular access to/from the site is proposed at two locations: one on the east via a new connection via the Cedar Avenue S alignment and intersection with SE 172nd Street, and one on the south side of the site through a future connection with the Sunnybrook Plat. A future connection to the undeveloped property to the north is also anticipated. The proposed plat is anticipated to be occupied by the year 2005. This report is structured in accordance with the City of Renton's Transportation Impact Analysis Guidelines. The scope of the traffic impact analysis was }^ established together with City of Renton Transportation staff The report documents the evaluation of traffic impacts and recommended mitigation measures. To analyze the traffic impacts of the Buttar Residential Plat, the following tasks were undertaken: 1111 • Assessed existing conditions and reviewed existing planning documents; • Described and assessed existing transportation conditions in the area; • Documented future without-project traffic forecasts and assumptions; • Documented existing public transit service, non-motorized facilities, and planned transportation improvements; • Estimated trip generation and documented distribution of project traffic; • Evaluated intersection LOS at six intersections for weekday AM and PM peak hour conditions; • Conducted LOS and queue analyses at the site access driveways; • Identified measures to mitigate impacts to the Renton street system. rTransportation Engineering Northwest 2 October 3,2002 i i.

Roadway characteristics are described in terms of facility type, number of lanes, and posted speed limits. The characteristics of these roadways are also shown in Figure 3. Carr Road is a four- to five-lane, east-west arterial with turn pockets and signals at major intersections. This street turns into S 43rd Street west of Talbot Road, and SE 176th Street east of SR-515. Carr Road has two travel lanes in each IY' direction, with a center left-turn lane at major intersections. On-street parking is not allowed, but sidewalks exist on both sides. The posted speed limit is 35 mph. A bus stop currently exists on both sides of Carr Road at Mill Avenue; the routes served are King County Metro routes 155, 163, and 169. Talbot Road is a two- to three-lane, north-south arterial with turn pockets and signals at major intersections. Sidewalks generally exist throughout, and on-street parking is prohibited. The posted speed limit is 35 mph in the site vicinity. Mill Avenue (103rd Avenue S)is a two-lane local access roadway with no posted speed limit, no sidewalks, and narrow lanes. It serves local access between Carr Road and 106th Place SE. Traffic Volumes ( Existing traffic volumes at the 6 study intersections were collected from the City of Renton and supplemented with addition intersection turning movement counts conducted by Traffic Data Gathering (TDG) in May 2001. Weekday AM and PM peak hour traffic counts were conducted in 2000 and 2001. To estimate year 2002 existing traffic volumes for those intersections counted prior to 2001, a three percent per year growth factor was applied to previous year count data. Figure 4 illustrates the existing AM and PM peak hour traffic volumes at the study intersections.

Public Transit Service King County-Metro Transit provides fixed-route public transportation services in the vicinity of the project site. Bus stops serving Metro routes 155, 163, and 169 are located on both sides of Carr Road at the intersection of Mill Avenue a couple blocks south of the site. Route 155 is an eastside route that connects Renton's Fairwood neighborhood and the Southcenter area of Tukwila. Service is provided throughout the day with stops approximately every hour. Route 163 runs between Downtown Seattle and various eastside locations, including the Tukwila, Fairwood-Renton, and Kent's East Hill. Morning service is provided into downtown, and afternoon service from downtown. Route 169 is an eastside route that connects the Renton Transit Center and the Kent Transit Center,with stops every 30 minutes throughout the day. Non-Motorized Transportation Facilities Curb, gutter, and sidewalks exist along Talbot Road and Carr Road. Mill Avenue does not have curb, gutter, or sidewalks. SE 38th Street and SE 37th Street, through the neighborhood adjacent to the Buttar Residential Plat site on the west, do not have curb, gutter, or sidewalk facilities. No striped bicycle lanes exist in the project site vicinity. Planned Transportation Improvements Future planned improvements in the project vicinity are identified in the City of Renton's 2003-2008 Six Year Transportation Improvement Program (TIP), and King County's six-year Capital Improvement Program (CIP). The following describes the planned improvements from each plan. • City of Renton TIP. Only one project listed in the City's current TIP would impact the study area roadway network. The project is the Trans- Valley ITS project, which is a joint project with King County. This project is in the study phase, and is intended to increase the efficiency of east-west traffic, enhance safety, improve speed and reliability within the corridor through a coordinated intelligent transportation system(ITS). The project would interconnect 22 signalized intersections from Southcenter Parkway to SE 184th Street, including upgrading signal controllers and adding video monitoring. King County has a TIB Transportation rTransportation Engineering Northwest 9 October 3,2002 Buttar Residential Plat—City of Renton,WA Traffic Impact Study Partnership Program (TPP) grant, with $50,000 in matching funds from Renton. Construction and implementation scheduled beyond year 2008. - • King County CIP. One project is planned in the vicinity area. It is the Can Road Improvement Study, which is a study of future alternatives for additional east-west capacity in the corridor, between Talbot Road and Benson Road. The project is in the preliminary stages of alternatives evaluation and comparison. The County's current CIP identifies the Improvement Study being complete in the summer of 2003; design is scheduled to be complete by the end of 2004. Construction is currently scheduled for the summer of 2005, although the road configuration and future improvements have not yet been identified. Because neither of the projects listed above have identified the specific improvements along the Carr Road corridor, no improvements were assumed in the operational analyses conducted for this project. ' a9 I Transportation Engineering Northwest 10 October 3,2002 , ' Buttar Residential Plat—City of Renton,WA Traffic Impact Study DETERMINATION OF IMPACT Project Trip Generation The Buttar Residential Plat is proposed to include 50 single-family residential lots. The site is currently vacant. The trip generation estimate for the Buttar Residential Plat is summarized in Table 1. The trip generation estimates are based on rates documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual 6th edition for Land Use Code 210 (Single-Family Housing). Table 1 Buttar Residential Plat Trip Generation Summary 1 Trip Trips Time Period Rate2 In Out Total Daily 9.57 250 250 500 AM Peak Hour 0.75 9 29 38 PM Peak Hour 1.01 33 18 51 1. ITE Trip Generation Manual, 6th Edition, 1997 Land Use Code 210(Single-Family Housing). As shown in Table 1, the proposed Buttar Residential Plat is estimated to generate a total of about 500 weekday daily trips, of which 38 trips would occur during the AM peak hour and 51 during the PM peak hour. Project Trip Distribution and Assignment The distribution of project-generated traffic was estimated based on existing travel patterns in the area and the locations of primary transportation facilities. In general,project trips are distributed as follows: • 50%West via Carr Road/ SE 43rd Street • 20%North via SR-515 (Benson) • 10%North via Talbot Road • 10%East via SE 176th Street • 10% South via SR-515 (108th Ave SE) i r Transportation Engineering Northwest 11 October 3,2002 I Buttar Residential Plat—City of Renton,WA Traffic Impact Study Based on these distribution patterns, project-generated traffic was assigned to the local street system for both AM and PM peak hour conditions. Figure 6 illustrates the AM and PM peak hour trip distribution and assignments. - Traffic Volumes Future traffic volumes with and without the proposed Buttar Residential Plat were estimated for AM and PM peak hour conditions in the year 2005. Future weekday AM and PM peak hour traffic volumes used for the LOS analyses at the study intersections were developed based on existing counts increased to account for background growth and the addition of some permit-pending projects in the area; the traffic generated by the Sunnybrook Plat was also included in the estimate of future volumes without the project. The City of Renton identified an annual growth factor of 3 percent to account for anticipated future year traffic growth. The weekday AM and PM peak hour traffic volumes in year 2005 without the project are shown on Figure 5. Adding the project-generated AM and PM peak hour trips, shown in Figure 6, to L' the future without-project traffic volumes (Figure 5), results in future with-project traffic volumes, as shown in Figure 7. i rTransportation Engineering Northwest 12 October 3,2002 t Talbot Rd S/S Grady Way j if .

Levels of service (LOS) were conducted for both weekday AM and PM peak hours for conditions in year 2005. LOS refers to the degree of congestion on a roadway or intersection. It is a r measure of vehicle operating speed, travel time, travel delays, and driving comfort. A letter scale from A to F generally describes intersection LOS. At signalized intersections, LOS A represents free-flow conditions-motorists experience little or no delays, and LOS F represents forced-flow conditions where the number of vehicles arriving exceed the capacity of the intersection. The LOS reported for signalized intersections represents the average control delay per vehicle entering the intersection. The LOS at stop-controlled intersections is reported for each movement. Therefore, the reported LOS does not represent a measure of the overall operations of the intersection. Table 2 outlines the LOS criteria for signalized and unsignalized intersections. Table 2 LOS Criteria for Signalized and Unsignalized Intersections Signalized Intersection Unsignalized Intersection Level of Service Delay Range(sec) Delay Range (sec) A < 10 <(10 B >10 to 20 >10 to 15 C >20 to 35 >15 to 25 D >35 to 55 >25 to 35 E >55 to 80 >35 to 50 F >80 • >50 Source: "Highway Capacity Manual",Special Report 209,Transportation Research Board,2000 L_ Intersection LOS were calculated using the methodology and procedures outlined in the 2000 Highway Capacity Manual, Special Report 209, Transportation Research Board using the Synchro software program. The weekday AM and PM peak hour intersection LOS analysis results at the study intersections are summarized in Table 3. ,October 3,2002 Transportation Engineering NorthWest 16 I , Buttar Residential Plat—City of Renton,WA Traffic Impact Study Site Access and Internal Circulation Vehicular Access. Vehicular access to/from the site is proposed at two locations: one on the east through a new connection via the Cedar Avenue S alignment and intersection with SE 172nd Street, and one on the south side of the site through a r future connection with the Sunnybrook Plat. A future connection to the undeveloped property to the north is also anticipated. The proposed Cedar Avenue connection would neck down from 42 feet to 30 feet in width along the access easement and connection to SE 172nd Street to the north (see also Figure 2 Site Plan). Emergency Vehicle Access. No separate emergency vehicle access is proposed because the plat would have two separate access roads. Future Connections. The site layout and proposed vehicular roadway network also takes into consideration properties on the north of the site. The location and design of the proposed on-site street system allows for a future connection to the northern property. Operational Analyses. Detailed operational analyses, including LOS and queuing, were conducted at the proposed site access locations for the weekday L AM and PM peak hours. The LOS and queuing analysis indicated that all of the accesses would operate at LOS A or better with minimal queues at peak times. Detailed LOS analysis worksheets for the project driveways are provided in Appendix B. i Non—Motorized Facilities Half-street frontage improvements are recommended on all City roadways where the existing property is being developed, and full-street frontage along all internal plat roadways. Frontage improvements should include curb, gutter, illumination, and sidewalks to separate pedestrians and motorists. ' 18 October 3,2002 Transportation Engineering Northwest Buttar Residential Plat—City of Renton,WA Traffic Impact Study MITIGATION MEASURES Long—Term. To mitigate long-term traffic impacts of the proposed Buttar Residential Plat, the City of Renton requires payment of a traffic impact fee based on the number of trips a project is estimated to generate during a typical weekday. The City's adopted impact fee is $75 per net new average daily trip. The proposed project is estimated to generate 500 trips per day. Site—Specific. The installation of site-specific improvements under SEPA is primarily determined by the results of the LOS analyses conducted at study area intersections and site access locations. Based on the intersection LOS results shown in Table 3, and the site access analyses,the addition of project-generated traffic would not cause a significant adverse impact at any of the intersections evaluated during weekday AM and PM peak hour conditions. Therefore, the installation of site-specific improvements under SEPA is not required. Site—Frontage. Half-street frontage improvements are recommended on all existing City roadways where the property is being developed, and full-street frontage improvements along all internal site roadways. Frontage should include curb, gutter, illumination, and sidewalks to separate pedestrians and motorists.

Buttar 4501 NE 4th Street Renton, WA 98059 Prepared by.• Talasaea Consultants, LLC 15020 Bear Creek Road N.E. Woodinville, WA 98072 24 October 2002 Buttar Property Wetland Study Report and Mitigation Plan EXECUTIVE SUMMARY SITE NAME: Buttar Property SITE LOCATION: The site is located northeast from the junction of State Route 167 and SW 43rd Street. Mill Avenue SE and Cedar Avenue South border the property to the east, and the site extends west towards 98th Avenue South (Morris Avenue South). The parcel is located in Sections-29 and 30, Township 23 North, Range 5 East, W.M. in Renton, Washington. CLIENT: Dr. and Mrs. Baljinder S. Buttar PROJECT STAFF: Bill Shiels, Principal; Oliver Grah, Senior Ecologist; Curtis Wambach, Ecologist; Teresa Opolka, Botanist FIELD SURVEY: Wetland Delineation on 10 April 2002 SENSITIVE AREAS: Talasaea delineated four wetlands, Wetlands A, B, C, and D, on the subject property. Generally, on-site wetlands consist of palustrine emergent seasonally flooded wetlands. Vegetation within the wetlands consists mainly of European pasture grasses. Wetland A is a Category 3 wetland. Wetland A is exempt from City regulation under Renton's code (RDR 4-3-050M(1)(b)) because this Category 3 wetland: 1) formed on top of legally placed fill material, 2) appears to have been created through the compaction of mine fill material, and 3) is an isolated wetland not regulated by the U.S. Army Corps of Engineers. Because Wetlands B and C are isolated Category 3 wetlands smaller than 5,000 square feet (sf) in size, they do not meet the size threshold for regulated wetlands under the City of Renton Development Regulations, thereby these wetlands are exempt. Wetland D is a Category 2 wetland requiring a 50-foot buffer. PROJECT IMPACTS: The proposed subdivision involves the grading of approximately 10 acres and will result in temporarily impacting 6,700 sf of regulated wetland buffer. Three low value, non-regulated wetlands (Wetlands A, B, and C)will be filled. These human-induced wetlands are small, isolated marginally wet areas that are dominated by exotic plant species. To minimize impacts from stormwater runoff during grading and construction, the most current erosion control Best Management Practices (BMPs) will be implemented. BMPs will be described in a Stormwater Pollution Prevention Plan (SWPPP) to be prepared and submitted at a later date. Storm runoff will be conveyed to a two-celled stormwater treatment pond, located in the northwestern corner of the property. To provide the required stormwater treatment capacity 6,700 sf of Wetland D buffer will be graded. IMPACT MITIGATION: Mitigation for 6,700 sf of temporary buffer impact through grading activities will occur on site through buffer restoration and enhancement. The 6,700 sf portion of graded Wetland D buffer will be restored at a 1:1 ratio in accordance with Renton Development Regulations Chapter 4-3- 050(C)(5)(f)(iii). Native trees and shrubs will replace the introduced European pasture grasses and Himalayan blackberry in some areas. Plantings will consist of Oregon ash, red alder, cottonwood, and western red cedar, as well as understory shrubbery, to compliment the existing forested land off-site to the south, west, and north of the subject property. Treated runoff from the stormwater treatment pond will be routed to infiltration trenches within the outer edge of the Wetland D buffer. Wetland hydrology will be augmented by treated water from the infiltration trenches, providing an additional source of hydrology. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page i Buttar Property Wetland Study Report and Mitigation Plan TABLE OF CONTENTS .

The site is the location of historical coal mining activities, which, along with agricultural activities, have altered the wetland patterns on the property (see Section 2.0). The property owner is considering developing or selling the property for residential use. Wetlands located on the subject property could present regulatory constraints to development. Because coal mining activities have altered wetland hydrology, soils, and vegetation on the property, the Atypical Situations approach was implemented (Environmental Laboratory, 1987). The purpose of this report is to describe the wetlands identified and delineated on the property. An analysis of impacts and proposed mitigation for those impacts will also be addressed within this report. The City of Renton, the U.S. Army Corps of Engineers, the Washington State Department of Ecology, and other agencies that may utilize information in this report. 2.0 GENERAL PROPERTY DESCRIPTION AND LAND USE The site is located in Sections 29 and 30, Township 23 North, Range 5 East, W.M. in Renton, Washington. The project site is located northeast of the State Route 167 and SW 43rd Street junction (Figure 1). The site is accessed from Cedar Avenue South, which borders the subject property to the east. State Route 515 is located east of Cedar Avenue South, and Mill Avenue SE is located south of the property. The approximately 10-acre property is currently unimproved. Dilapidated farm buildings are located in the northeast corner of the property and immediately off site. The topography slopes downward from east to west for a maximum elevation change of approximately 150 feet. Dominant vegetation consists of European pasture grasses. Large patches of Himalayan blackberry occur throughout the site. Some black cottonwood, red alder, and Oregon ash saplings occur in the western portion of the property. No large trees occur on site, other than along the southern, western, and part of the northern property lines. A portion of the site contains an abandoned coal mine. Coal mining activities altered the soils, vegetation, and hydrology throughout the entire site. On-site wetland patterns were consequently altered or created as a result of mining activities. These activities included clearing, grading, and placing mine rock fill material. Based on the Draft Coal Mine Hazard Assessment and Preliminary Geotechnical Engineering Study (2002), mine rock backfill was stockpiled on site, dumped and spread throughout most of the site, and mixed in with soils across most of the property. Coal particles are visible at the surface and are integrated into the soils. Coal tailings give an carbon enriched and black appearance to the soils. The mine deposited fill (coal tailings) was placed onto the surface from approximately 1942 to 1948 (Terra Associates, Inc., 1991). Abandoned coal mine workings extend throughout the vicinity of the subject property (Cornerstone Geotechnical, Inc., 2001). Mining activities that include tailing deposits, mobile heavy machinery, and surface blasting may have contributed to the loss of surface vegetation during the late 1940s. Mobile heavy machinery compacted mine rock fill throughout the areas of deposited tailings. Compacted mine rock fill likely altered site hydrology. Mine rock fill with a smaller particle size and with greater degree of compaction tends to act as a barrier to infiltration and percolation.

It is likely that less compacted, more porous mine rock fill sits on top of more compacted, less porous mine rock fill with very low percolation rates, causing a perched water table in some areas. The surrounding properties consist of residential developments and undeveloped lots. Forested lots border the property to the south, north, and west. Multifamily residential developments border the site to the east. Developments in the vicinity of the Buttar property consist of single and multi-family residences. y . 3.0 METHODOLOGY The wetland analysis of the subject property involved a three-part effort. The initial effort consisted of a preliminary assessment of the site (and its immediate surroundings) using published information on local environmental conditions. The second component involved a field surveyin which direct observations and measurements ments of soils, hydrology, and vegetation were made to determine wetland presence, type and functional value, and to provide a preliminary delineation of wetland boundaries (see Field Investigation section below). A third component involved shallow groundwater monitoring and further field investigation to provide a final wetland delineation. 3.1 Background Data Review Background information reviewed prior to field investigations included the following documents: • Renton Wetlands and Stream Inventory (Renton, October 2000) • National Wetlands Inventory Map (Renton Quad), U.S. Fish and Wildlife Service (USGS, 1989) • Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation (Icicle Creek Engineers, Inc., 2002) • King County Soil Survey (USDA, Soil Conservation Service, 1973) • King County Sensitive Area Folio and Wetland Inventory (King County, 1990) • United States Hydric Soils List (U.S. Department of Agriculture, Soil Conservation Service, 1991) • Washington State Hydric Soils List (Iowa State University, 1995) 3.2 Field Investigation General Investigation. A general site reconnaissance was conducted in April 2002 to gain an overall impression of the site's existing environment and wetland pattern. Observations were made of the general plant communities, wildlife habitats, and locations of potential wetland areas. Present and past land use practices were also noted, as were significant geological and hydrological features. Once wetland suspect t p eland areas were identified, wetland boundaries were preliminarily delineated on 10 April 2002 using the procedures outlined in both the Army Corps of Engineers (1987) and the State Department of Ecology (1997) wetland identification and delineation manuals. Since soils are black from coal tailings and vegetation is dominated by FAC plant species, shallow groundwater monitoring data and additional test pits were evaluated to provide a final wetland delineation. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 2 Buttar Property Wetland Study Report and Mitigation Plan Hydrophytic Vegetation. Plant species were identified according to the taxonomy of Hitchcock and Cronquist (1973). Wetland status of plant species was assigned according to the List of Plant Species that Occur in Wetlands, published by the U.S. Fish and Wildlife Service (Reed, 1996). Wetland vegetation classes were determined in-accordance with the U.S. Fish and Wildlife Service's system of wetland classification (Cowardin, et. al., 1979). The Corps of Engineers (COE) (Environmental Laboratory, 1987) and Department of Ecology (DOE) (DOE, 1997) manuals describe a wetland rating system for plants: Each plant species is assigned a probability of occurrence within wetlands, which is referred to as { its wetland status. The wetland rating system is as follows: • obligate (OBL), (Probability >99% occur in wetlands) • facultative wetland (FACW), (Probability 67% to 99% occur in wetlands) • facultative (FAC), (Probability 34% to 66% occur in wetlands) • facultative upland (FACU), and (Probability 1% to 33% occur in wetlands) • upland (UPL) (Probability <1% occur in wetlands) In general, under the COE and DOE methodology, more than 50 percent of the dominant plant species within a test plot must be rated FAC or wetter (i.e., FACW, OBL) to satisfy the wetland criteria for hydrophytic vegetation. Dominant species are those that have a percent cover greater or equal to 20 percent within the test plot. Only dominant plant species were considered in the data analysis. Hydric Soils. The COE and DOE manual describes hydric soil indicators that typically occur in wetlands. A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part. Anaerobic conditions cause redoximorphic features to develop, which can be evidenced through the observation of mottling or gleying in the soil. Soil on the site was considered hydric if one or more of the following characteristics occurred: • organic soils or soils with an organic surface layer, • matrix chroma just below the A-horizon (or 10 inches, whichever is less) of 1 in unmottled soils, or 2 or less if mottles were present, or • gleying immediately below the A-horizon. Hydrology. Indicators of wetland hydrology may include, but are not necessarily limited to: wetland patterns, drift lines, sediment deposition, watermarks, historic records, visual observation of saturated soils, visual observation of a shallow water table, and visual observation of inundation. Shallow groundwater was evaluated using shallow groundwater monitoring wells to supplement hydrological data. Eight shallow groundwater wells were installed across the marginally wet areas located on subject property to determine the extent of wetland hydrology (Appendix A). General installation methodology was based on procedures described in Installing Monitoring Wells/Piezometers in Wetlands (WRP, 1993). Observations of the hydrologic regime are normally made within 18 inches of the soil surface; however, the wells on the project site were installed deeper than normally required to provide a better understanding of site hydrology. The average shallow groundwater well depth was 37 inches over the period of 3 months during the spring of 2002. Wells were placed in areas where wetland hydrology 24 October 2002 Talasaea Consultants, LLC 717-WIRpt4(240ct02).doc Page 3 Buttar Property Wetland Study Report and Mitigation Plan was questionable. Groundwater monitoring began on 11 March 2002. Water levels were generally monitored twice a week between 11 March and 21 May 2002. . Precipitation between monitoring events was measured using an on-site rain gauge. A more complete precipitation record was obtained from Seatac International Airport weather station, Seatac, WA. This data was used to compile the cumulative precipitation for the days preceding the monitoring events. Determination. Descriptions of vegetation, soils, and hydrology were made at various locations along the interface of wetland and upland areas. Because the site was highly disturbed through coal mining and agricultural activities, the "atypical situations" approach and "comprehensive methodology"was implemented based on the COE and DOE manuals, rather than the routine on-site approach. Based on this comprehensive methodology, well data information was also considered in this determination (Appendix A). Test plot data sheets are attached to this report in Appendix B. Wetland boundaries were then delineated from this information. These data sheets document the vegetation, soils, and hydrology information that aided in the determination of wetland boundaries. 4.0 RESULTS 4.1 Analysis of Existing Information National Wetland Inventory National Wetlands Inventory (NWI) maps (Renton Quadrangle, 1989) developed by the U.S. Fish and Wildlife Service (USFWS) indicate that no wetlands are located on the site (Figure 2). Likewise, the King County Wetland Inventory identifies no on-site wetlands in their survey results. Since these maps are only general inventories based largely on aerial photographs, and because wetland areas change over time, a field investigation was necessary to ensure that any wetlands were identified and their boundaries accurately delineated. Natural Resources Conservation Service Mapping AA q The Natural.Resources Conservation Service (NRCS) has mapped the entire site as Alderwood gravelly sandy loam (AgC), 6 to 15 percent slopes (Figure 3). Although this mapping unit is not listed as hydric by the NRCS and is generally well drained, they may have hydric soil inclusions. The soil survey lists hydric inclusions within the Alderwood series as Norma, Bellingham, Seattle, Tukwila, and Shalcar soil series. 4.2 Analysis of Field Conditions Four wetlands were identified on the subject property, labeled Wetlands A, B, C, and D (Figure 4). Wetland D was delineated by Talasaea during April and May of 2001, as part of the Sunnybrook plat to the south of the subject property. Wetland D was delineated a year prior to the wetland delineation on the Buttar property. See Section 6.0 "Regulatory Considerations" for information pertaining to wetland classification, buffers, and replacement ratios. Functional values of wetlands are described in Section 5.0 "Wetland Functions and Values." 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 4 _..-_.

Coal mine fill, deposited as a result of former coal mining activities, blankets almost the entire property. This coal-laden fill was stockpiled and graded out in the central portion of the property. Coal mine fill worked into the soil through grading and mining activities, created the superficial appearance of black, organically rich hydric soils, even in areas that are obviously uplands. Through grading - activities, heavy machinery has compacted some of this fill material, creating a perched water table in some areas (See Icicle Creek Engineers, 24 September 2002). Dominant plant species consist of European pasture grasses probably planted for erosion control concurrent with and subsequent to mining activities and also for grazing by domesticated animals during the property's agricultural history. Invasive exotic plant species, especially Himalayan blackberry, have invaded portions of the site. These non- native plant species are a result of site disturbance and are not strong hydrophytic indicators. Wetlands are dominated by species that are facultative (FAC) to wet conditions. FAC species have 50 percent probability of occurrence in uplands and in wetlands. The delineation of Wetland A was based on the degree of soil saturation, the distribution of soft rush (Juncus effusus; FACW), and the presence of redox inclusions (mostly ( ly concretions and oxidized rhizoshperes). However, redox inclusions could have formed in coal seams through non-wetland processes prior to mining. Soils were examined closely for oxidized rhizospheres that appear to have formed around a living root. Because of the disturbed nature of this wetland, shallow groundwater monitoring was used to assist in determining if the hydrology criteria was met. Wetland A Description. Wetland A (12,211 sf), located in the central portion of the subject property, is an isolated, marginally wet area that formed on top of compressed fill material (Icicle Creek Engineers, 24 September 2002). Based on the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation (Icicle Creek, 2002); a 2-foot thick layer of mine rock fill and reworked topsoil is underlain by a thin layer of compacted fill that is causing shallow, perched groundwater conditions in Wetland A. The layer of fill placed over upland areas was likely compacted by heavy equipment working in this area when the surficial fill and topsoil was reworked. Wetland A formed on top of a slightly convex mound of fill material. These wet conditions occur in an area that is slightly higher in elevation than the surrounding uplands. This unusual condition is possible because of the perched water table caused by a layer of compacted fill. This mine rock fill material nearer the surface has higher permeability rates and lower pore pressure such that free water readily permeates to the compacted layer. This compacted layer does not allow for regular infiltration of surface water and thereby perches that water near the surface. Mine rock fill with a smaller particle size and with greater degree of compaction appears to have acted as a barrier to infiltration in Wetland A. Further complicating groundwater patterns, in some areas, coal particles soak-up water like a sponge and hold that water above the compacted layer. A more porous mine rock fill sits on top of compacted, less porous mine rock fill, confounding normal groundwater hydrology and creating an atypical situation. i - 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 5 Buttar Property Wetland Study Report and Mitigation Plan Cowardin Classification. Wetland A is a palustrine, emergent, seasonally-flooded (PEMC) wetland (see Cowardin et al., 1979). Plants. Wetland A is partially dominated by introduced plant species, which mostly include FAC-dominated.European pasture grasses (Table 1). However, the wetland boundary encircles a well-defined patch of soft rush (FACW). The soft rush is located on top of the slightly convex mound of fill material. Since the plant species in the wetland are primarily the result of species introduction and of disturbance features, these species are not strong indicators of wetland conditions. Soils. Soils are black (10YR 2/1) at the surface to 10 inches and very dark grayish brown (10YR 3/2) below 10 inches. A sandy fine loam horizon (brown to dark yellowish brown 10YR 4/3) was identified approximately 18 inches below the surface within portions of Wetland A. Large and small chunks of coal were visible with the naked eye. Microscopic evaluation of soil samples taken from Wetland A reveal the shiny surfaces of coal dust 'intermixed with sandy loam. Talasaea's interpretation of soil conditions in Wetland A concurs with that described in the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation (Icicle Creek, 2002). It appears that surface soils are primarily composed of coal mine rock fill intermixed with topsoil, producing a black color that is also observed in uplands throughout the property. Because of these disturbance features, soil color is a weak indicator of hydric soils in Wetland A. Because redox inclusions may have formed in coal seams deep underground prior to coal extraction and subsequent coal waste production, these typical hydric soil indicators were also considered to be weak. The soil criteria was satisfied if living roots were visible within oxidized rhizospheres, which suggests that these redox features were formed more recently by anaerobic soil conditions typical of wetlands, rather than by historical conditions within a coal seam. General Hydrology. Soils were saturated to the surface in some areas during the growing season (Appendix B). Some scattered, shallow inundation was evident in this wetland. Shallow groundwater monitoring of the soil surface was also implemented to determine that the hydrology criterion was satisfied (Appendix A). Table 1.

Wetland B (1,275 sf) is a small, isolated, wet depression located on the northwestern portion of the property. This depression appears to be formed through grading activities during prior land use, probably during coal mining activities. Top soils appear to have been completely scraped from the soil surface, exposing unweathered till. The relatively impermeable unweathered till catches rainwater and holds it at the soil surface within the shallow depression of Wetland B. Cowardin Classification. Wetland, B) is a palustrine, emergent, temporarily-flooded (PEMA) wetland (see Cowardin et al. 1979). Plants. Dominant vegetation consists of FAC-dominated European pasture grasses (Table 2). Some bare ground occurs in seasonally inundated areas. A red alder and Oregon ash canopy extends over the northern edge of the wetland from beyond the fence line that marks the northern property boundary. Soils. Soils are gray (2.5Y 5/1) and composed of a relatively impermeable, dense unweathered till. Yellowish red mottles (7.5YR 5/6) are large and abundant throughout the soil matrix. General Hydrology. Although seasonal inundation was obvious earlier in the growing season, no standing water was observed in late May and early June. During late spring, soils were relatively dry at the surface and were moist below the surface to 18 inches. Table 2.

Wetland C (Approximately 740 sf) is a small, isolated wetland that formed in a shallow depression on top of a dirt access road. Tire ruts collect water that pools on compressed soil. Cowardin Classification. Wetland A is a palustrine, emergent, temporarily-flooded (PEMA) wetland (see Cowardin et al., 1979). 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 7 Buttar Property Wetland Study Report and Mitication Plan Soils. The soil is similar in composition to that found throughout the property. Coal fragments ' are visible in the soil, producing a dark color. Redox inclusions were also visible within the soil matrix. Similar to Wetland A, redox inclusions may have formed within coal seams prior to mining activities, so active rhizospheres were used as primary hydric soil indicators. Plants. The dominant plant species are European pasture grasses, similar to that of Wetlands A and B, along with Himalayan blackberry. General Hydrology. The hydrology criterion was satisfied through shallow groundwater monitoring. However, the source of hydrology apparently was supplied by a blockage in an off- site drainage ditch located approximately 50 feet to the east of Wetland C. Old tires, newspapers, bottles, appliances, and other garbage illegally dumped in the ditch, as well as other debris, was responsible for blocking the normal flow within the ditch. The ditch has since been cleaned out and the obstruction was removed. Thereby, the artificial source of hydrology no longer exists and this human-induced wetland may disappear. Wetland D Description. Wetland D (59,138 sf, 28,572 sf on-site) is a wetland system located on the southwestern portion of the property and extends off site to the south and west. Wetland vegetation classes consist of: 1) palustrine emergent (on site) and 2) palustrine forested (off site) (see Cowardin et al., 1979). The areas of emergent wetland are located exclusively on the project site. This wetland appears to have formed as the result of obstruction and subsequent departure of flow from an unmaintained ditch located along the southern property line. The ditch was originally channelized along the property line and routed to a culvert located east of the property. Erosion and sedimentation has causing the original excavated channel to fill in with sediment and debris. Drainage from the ditch now flows onto the southwestern portion of the subject property, supplying the hydrology for Wetland D. The drainage extends through Wetland D, and splits into two separate branches west of the property boundary. The northern branch eventually drains to an open conveyance along the South 35th Street right-of-way. The southern branch drains to a culvert, which the original ditch was routed. This culvert is part of an urban stormwater network draining roads and parking lots. No evidence of fish life or usable habitat was found in this ephemeral drainage. This stormwater-fed, flashy drainage does not maintain flow capacity to support resident or anadromous fish populations. Cowardin Classification. Wetland C is a palustrine, emergent, seasonally-flooded (PEMC) wetland on site and a palustrine, forested, seasonally-flooded (PFOC) wetland off-site (see Cowardin et al., 1979). Plants. 'European pasture grasses and soft rush dominate the on-site portion of Wetland D. Dominant plant species occurring in this wetland are listed in Table 3. The off-site portion is dominated by red alder and Oregon ash. Soils. Soils are black (10YR 2/1) and were saturated to the surface at the time of the field study. Black soils in Wetland D may be the result of coal tailings, as with Wetland A. Hydrology. Seasonal inundation was obvious during wetter months earlier in the growing season. Soils appear to be saturated throughout most of the year. Hydrology appears to be solely supplied by an overflowing, unmaintained ditch located along the southern property line, as previously discussed. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 8 Buttar Property Wetland Study Report and Mitigation Plan Table 3.

These functions were semi- quantitatively assessed using the Wetland and Buffer Functional Analysis Methodology developed by Cooke Scientific Services, Inc. (Cooke, 2000). The scores from the analysis of each parameter are summarized in Table 4. Wetland A. Wetland A is an isolated, marginally wet area dominated by European turf grass species. This marginally wet area provides low to very low values for stormwater functions because of its isolated nature and relatively small size. Biological functions scored very low because non-native grasses primarily dominate wetland vegetation. These grasses provide little habitat for native wildlife species. Biological functions also scored very low because no habitat features, such as trees, snags, stumps, woodpiles, or boulders occur in this wetland. The wetland is located on private property and has extremely low socioeconomic or cultural value. Wetland B. Wetland B is an isolated depression excavated into impermeable, unweathered till. Without a surface water connection, hydrology is fed primarily by local precipitation and possibly by minimal groundwater. Because of its isolated nature, minimal vegetation, and small size, this wetland generally scored extremely low for stormwater functions. Because of minimal vegetation and no habitat features, biological functions are extremely low to insignificant. Similar to Wetland A, cultural functions scored extremely low because the wetland is located on private property and does not have commercial, historical, recreational, educational, or aesthetic value. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 9 Buttar Property Wetland Study Report and Mitigation Plan Wetland C. Wetland C is a small, isolated depression that formed in tire ruts. Without a surface water connection, hydrology is fed primarily by local precipitation and possibly by minimal groundwater.

Wetland D is a shallow, wet depression located in a relatively flat area both on and off site. Both the on-site and off-site portions were included in this evaluation. The on- site portion of Wetland D is a palustrine emergent wetland dominated by pasture grasses and soft rush. Himalayan blackberry dominates the fence line within Wetland D. The off- site portion of Wetland D is forested and has an understory dominated by Himalayan blackberry and, to a lesser extent, salmonberry. Stormwater functions are moderate to low because of its moderate size and forested cover. Biological support and habitat functions are moderate to low, based on the moderate volume of organic accumulation in this relatively young forest. 6.0 REGULATORY CONSIDERATIONS Wetland A Exemption (RDR 4-3-050M(1)(b)). Wetland A is not a regulated feature under Renton's Code (RDR 4-3-050M(1)(b)) because this Category 3 wetland: 1) formed on top of legally placed fill material, 2) appears to have been created through the compaction of mine rock fill material, and 3) is an isolated wetland not regulated by the Corps. Based on the Coal.Mine Hazard Assessment and Geotechnical Engineering Evaluation, Wetland A formed on top of legally placed and compacted fill material. Mine rock fill material was spread over the area of Wetland A by heavy machinery. Compaction of mine rock fill material confounded groundwater hydrology in the area of Wetland A. Compaction and water holding capacity of this fill material apparently contributed to the formation of tentitive wetland conditions. Exemption RDR 4-3-050(C)(5)(f)(ii). Under RDR 4-3-050(C)(5)(f)(ii), any activity affecting hydrologically isolated Category 3 wetland no greater than five thousand (5,000) square feet is exempt. Other Regulatory-Considerations. The State Department of Ecology reserves authority to use administrative orders to regulate projects involving isolated wetlands under RCW 90.58. Ecology has authority over "Waters of the State". Because isolated wetlands are "waters of the State" under RCW 90.58, Ecology may implement regulatory authority over Wetland A. Because Wetland A is a hydrologically isolated, it is exempt from regulation by the U.S. Army Corps of Engineers. The Corps does not regulate the alteration of hydrologically isolated wetlands. Based on the 6 January 2001 U.S. Supreme Court ruling in Illinois, isolated wetlands are no longer"Waters of the United States", and thereby not regulated'by the Corps under the Clean Water Act. Wetland B Exemption RDR 4-3-050(B)(7)(a). Wetland B is a Category 3 wetland not regulated under the City's Code (RDR 4-3-050(B)(7)(a)), because it does not meet the size threshold of 5,000 sf. Although Wetland B is exempt from Renton's regulatory consideration, other regulatory constraints may apply. • Exemption RDR 4-3-050(C)(5)(f)(ii).

Wetland D Wetland D is classified as Category 2 wetland under the City of Renton's Development Regulations (RDR 4-3-050(B)(7)(b)) (Table 5). The standard buffer width for Category 2 wetlands is 50 feet (RDR 4-3-050(M)(6)(c)). Permanent Disturbances. The replacement-to-loss ratio for permanently disturbed emergent Category-2 wetlands is 1.5 to 1 for wetland restoration or creation (RDR 4-3- 050(M)(11)(e)). Exemption for Temporary Disturbances RDR 4-3-050(C)(5)(f)(iii). Under RDR 4-3- 050(C)(5)(f)(iii), "temporary disturbances of a wetland [or its buffer] due to construction activities that do not include permanent filling may be permitted; provided, that there are no permanent adverse impacts to the critical area or required buffer, and areas temporarily disturbed are restored at a 1:1 ratio". Category 1 wetlands and Category 2 forested wetlands require a 2:1 enhancement ratio. Because the on-site portion of Wetland D is a Category 2 emergent wetland, the enhancement ratio should be 1:1. This exemption requires a written request addressed to and subsequent permission authorized by the Department Administrator. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 12 Buttar Property Wetland Study Report and Mitigation Plan Table 5.

Under RDR 4-3-050(M)(6)(e)(ii), buffer width reduction is allowed if a buffer enhancement plan is implemented. The buffer enhancement plan must involve the installation of native vegetation and substantiate that the enhanced buffer will be equal to or improve the functional attributes of the buffer. An enhanced buffer shall not result in greater than a 25 percent reduction in the buffer width, and the reduced buffer shall not be less than 25 feet wide. Greater buffer width reductions require review as a variance per RDR 4-3-050(N)(3) of this Section. Exemption for Stormwater Discharge to Wetlands RDR 4-3-050(C)(5)(d)(i). New surface water discharges to Wetland D and its buffer from detention facilities, pre-settlement ponds, - or other surface water management structures are exempt from City regulation under RDR 4-3-050(C)(5)(d)(i). The stormwater discharge to the wetland or its buffer: 1) must meet the requirements of the City's Storm and Surface Water Drainage Regulations (RMC 4-6-030); 2) will not result in significant changes in the water temperature or chemical characteristics of the wetland water source; and 3) does not cause an increase in the existing rate of flow unless it can be demonstrated that the change in hydrologic regime would result in greater wetland functions and values. This exemption requires a written request addressed to and subsequent permission authorized by the Department Administrator. Exemption for Buffer Disturbances RDR 4-3-050(C)(7)(a)(ii). Under RDR 4-3- 050(C)(7)(a)(ii), stormwater management facilities in critical area buffers are exempt from regulation by the City. Stormwater management facilities defined Under this section include stormwater dispersion outfall systems. These systems must be designed to minimize i ! 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 13 Buttar Property Wetland Study Report and Mitigation Plan impacts to the buffer. The site topography requires that the location of the dispersion outfall be within the buffer to allow hydraulic function. This exemption requires a written request addressed to and subsequent permission authorized by the Department Administrator. 7.0 WILDLIFE General wildlife observations were made during the wetland reconnaissance. Table 6 summarizes the species or evidence of that species' presence observed on the project site during the reconnaissance. Wetland observations on the property were typical of urban/suburban-adapted species. Crows and robins were numerous throughout the site and European starlings were observed in grassy areas. Rufus-sided towhee, white- crowned sparrow, and black-capped chickadee were observed at the edge of the forest near the southern property boundary. Winter wren, black-headed grosbeak, and northern flicker were observed near the southern edge of the property. A red-tailed hawk was observed soaring overhead on thermals. No raptor nests were observed on the subject property. Table 6.

No raptor nests were observed on the subject property. The red-tailed hawk is not State-listed, Federally-listed, or listed as a priority species by the State. Therefore, the presence of a red-tailed hawk should not be a regulatory constraint. 8.0 DEVELOPMENT IMPACTS Core Design has proposed a residential development consisting of 49 single-family lots located on the 10-acre site in the City of Renton, Washington (Figure 5). The development infrastructure includes a system of asphalt-paved roads, driveways, and stormwater facilities. The development will occupy land that is currently undeveloped and contains several dilapidated farm structures. The proposed action involves the grading of approximately 10 acres and will result in temporarily impacting 6,700 sf of regulated wetland buffer. Three low value, non-regulated wetlands (Wetlands A, B, and C) will be filled. These human-induced wetlands are small, isolated marginally wet areas that are dominated by exotic plant species. Wetland A is exempt because it has formed on top of compacted fill material and is not regulated by the U.S. Army Corps of Engineers.. Wetlands B and C are isolated Category 3 wetlands smaller than 5,000 sf, and thereby exempt under Renton code. To minimize impacts from stormwater runoff during grading and construction, the most current erosion control Best Management Practices (BMPs) will be implemented. BMPs will be described in a Stormwater Pollution Prevention Plan (SWPPP) to be prepared and submitted at a later date. Storm runoff will be conveyed to a two-celled stormwater treatment pond, located in the northwestern corner of the ert ro p p y. The stormwater treatment pond will be constructed in the lowest portion of the property that is not a sensitive area. The pond will receive and treat storm runoff from the entire proposed development. To provide the required stormwater treatment capacity, 6,700 sf of Wetland D buffer will be graded. Buffer alteration will not occur within 25 feet of Wetland D. 9.0 MITIGATION FOR SENSITIVE AREA IMPACTS Mitigation for 6,700 sf of temporary buffer impact through grading activities will occur on site through buffer restoration and enhancement (Table 7). The 6,700 sf portion of graded Wetland D buffer-will be restored at a 1:1 ratio-in accordance with Renton Development . Regulations Chapter 4-3-050(C)(5)(f)(iii). The impacted portion of the Wetland D buffer currently consists of disturbed coal-rich soils and introduced European pasture grasses and some Himalayan blackberry. The significantly disturbed soils in the Wetland D will not be further degraded through grading activities. Native trees and shrubs will replace the introduced European pasture grasses and some Himalayan blackberry. Plantings will consist of Oregon ash, red alder, cottonwood, and western red cedar, as well as understory shrubbery, to compliment the existing forested land off site to the south, west, and north of the subject property. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc - Page 15 I • • I . • • 8028 I .�!y-±..,� .,..m•LYJ - _ q.. 9100 9a.09 —\ i I f�. _ a, 81.80 p Bl.00 8 8 / a 4` i' � ��l� 27 I �' 8 40 s 8 45 111 46 S �_ i 41 (# ! _ �� 16! ;," I0000 DA00 9A00 92)e `--_ 4 ' \` --i :I .ill_---- N v )--_ k 1 N. e''i i. ��% �?�i ,;i 1s 29 s @�. 39 a ij S 44 �I I N 1 i • I 0,, .'%' �', i;14 i;:''•a 26 - s $ 34 Wiz— � +�=42 s f•k 47 :24 il m. �r ` .� 1.; •+ 0 00 // - :. `� _,, ..\., i 4 i s N 25 . _g$ 8 30 y1 s 33 s 35,) 4 ��� 8 + 48 $ / 1,._�\ ':\ `l-�I.i - ee.v ! .m._eaoo .1 ! 38 .,,moo ,� L 1-.96.09 „',�s'"S • w�'-�- ,.: ,\� - mil.

Because mostly herbaceous vegetation would be removed, temporal loss would be minimal. Treated runoff from the stormwater treatment pond will be routed to infiltration trenches within the outer edge of the Wetland D buffer in accordance with Renton Development Regulations Chapters 4-3- 050(C)(7)(a)(ii) and 4-3-050(C)(5)(d)(i) (see Section 6.0 above). Wetland hydrology will be augmented by treated water from the infiltration trenches, providing an additional source of hydrology. 9.1 Goals and Objectives Goal 1: Replace and improve functions and values lost due to temporary impact of 6,700 sf of Category 2 wetland buffer. Objectives: • Restore and enhance 6,700 sf of graded Wetland D buffer at a 1:1 ratio in accordance with Renton Development Regulations Chapter 4-3-050(C)(5)(f)(iii)., • Remove and control exotic and invasive plants, • Provide dependable source of high-quality water to wetland by routing treated runoff from the on-site stormwater treatment pond to Wetland D via infiltration trenches, • Install bird-nesting boxes and bat-roosting boxes on snags placed in the buffer area, • Plant a wide variety of shrubby species interspersed with seasonal water to promote enhanced amphibian habitat, • Plant a variety of sizes and species of native evergreen and deciduous trees and shrubs to create structural diversity and habitat improvement, and • Incorporate informational signage to educate public about the wetland ecosystem. 9.2 Plantings Plant species will be chosen for a variety of qualities, including: adaptation to specific water regime, value to wildlife, value as barrier or buffer vegetation, pattern of growth, and aesthetic value. Native tree, shrub, and herbaceous species will be planted to increase both the structural and species diversity of the mitigation and buffer areas, thereby increasing the area's value to wildlife for food and cover. Species of vegetation that are 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 16 Buttar Property Wetland Study Report and Mitigation Plan both beneficial to wildlife and that inhibits human intrusion will be used in areas where human exclusion is desired. Plant materials will consist of a combination of bare-root specimens, container plants, and cuttings. 9.3 Habitat Features Bird-nesting and bat boxes will be installed to enhance wildlife habitat. Brush piles will also be placed throughout roughout the mitigation areas to provide important cover for various birds and small mammals. Boulders recovered from site excavation (if available) will be placed in small piles throughout the mitigation area. These piles can provide habitat for reptiles and small mammals. 10.0 CONSTRUCTION MANAGEMENT Prior to commencement of any work by contractors in the mitigation area, the clearing limits will be staked and fenced. Silt fences will be installed at the clearing limits adjacent to sensitive areas and significant habitat features and vegetation to be retained will be clearly marked in the field. Areas will be designated for stockpiling of topsoil and habitat features. A wetland biologist or landscape architect will regularly supervise plan implementation during construction to ensure that the objectives and specifications of the mitigation plan are met. Any significant modifications to the design that may occur as a result of unforeseen circumstances will be approved by the owner, the City, and Talasaea Consultants prior to their implementation. 11.0 MONITORING METHODOLOGY Performance monitoring of the mitigation area will be conducted for a period of five years, with reports submitted annually to the City of Renton according to the schedule presented in Table 8. Reports will include: a) photo-documentation, b) estimates of percent vegetative cover, plant survival, and undesirable species, c) water quality and hydrology, d) wildlife usage, and e) an overall qualitative assessment of project success for the wetland mitigation.

PM= Performance Monitoring R= Report MR= Maintenance Memo and Review 11.1 Vegetation Permanent vegetation sampling points or transects will be established to evaluate all of the representative plant communities. The same monitoring locations will be re-visited each year with a record kept of all plant species found. Vegetation will be recorded on the basis 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(240ct02).doc Page 17 Buttar Property Wetland Study Report and Mitigation Plan of relative percent cover of the dominant species within the vegetative strata. All monitoring will be conducted by a qualified biologist. Photo-points will be established from which photographs will be taken throughout the. monitoring period. These photographs will document general appearance and progress in plant community establishment in the mitigation area. Review of the photos over time will provide a semi-quantitative representation of a successful planting plan. Monitoring and photo-point locations will be shown and described in the baseline performance assessment report. 11.2 Water Quality and Hydrology - During each monitoring event, an assessment will be made of the water regime within the mitigation area to ensure that proper hydrological conditions exist within both the wetland and its buffer. Water quality will be assessed qualitatively, unless it is evident there is a serious problem. In such an event, water quality samples will be taken and analyzed in a laboratory for suspected pollutants. Qualitative assessments of water quality may include: • oil sheen or other surface films, • abnormal color or odor of water, • stressed or dead vegetation or aquatic fauna, • turbidity, and • absence of aquatic fauna. 11.3 Wildlife Birds, mammals, reptiles, amphibians and invertebrates, which are readily observable (either by direct or indirect means) will be identified and recorded in the wetland and buffer areas. Direct observations include actual sightings, while indirect observations include tracks, scat, nests, song, or other indicative signs. The kinds and locations of habitat with greatest use by each species will be noted, as will any breeding or nesting activities. 11.4 Success Criteria Success of plant establishment within the mitigation area will be evaluated on the basis of both percent survival and percent cover. For woody planted species, success will be based on at least an 85 percent survival rate of all planted trees and shrubs, or at least 80 percent cover of equivalent recolonized native species, by the end of the five-year monitoring period. Success for herbaceous species will be based on an 80 percent cover of desirable plant species by the end of the five-year monitoring period. Exotic and invasive plant species will be maintained at levels below 20 percent total cover. These species include Scot's broom, Himalayan and evergreen blackberry, purple loosestrife, hedge bindweed, Japanese knotweed, English ivy, and creeping nightshade. Removal and control of these invasive plant species will be achieved through routine maintenance in the mitigation areas. Such maintenance is necessary to achieve successful plant establishment and compliance with the 20 percent threshold for the listed exotic/invasive species. Removal of undesirable species will occur by hand whenever possible. No chemical treatment will be employed without prior approval by the City. 24 October 2002 Talas aea Consultants,LLC 717-WIRpt4(240ct02).doc Page 18 Buttar Property Wetland Study Report and Mitigation Plan 12.0 MAINTENANCE (M) and CONTINGENCY (C) Established performance standards for the project will be compared to the monitoring results in order to judge the success of the mitigation project. Contingency will include the items listed below and would be implemented if these performance standards are not met. Maintenance and remedial action on the site will be implemented immediately upon completion of the monitoring event (unless otherwise specifically indicated below). 1. Replace dead plants with the same species or a substitute species that meets the goal and objectives of the mitigation plan (C). 2. Re-plant areas after reason for failure has been identified (e.g., moisture regime, poor plant stock, disease, shade/sun conditions, wildlife damage, etc.) (C). 3. Perform corrective measures, as necessary, to provide adequate hydrology to support the desired wetland plant community (C). 4. Irrigate all planted areas with a temporary above ground system for a minimum of two years following plant installation (M). 5. Excavate, as needed, to correct alterations of surface wetland patterns (C). 6. Remove/control weedy or exotic invasive plants twice yearly by manual or chemical means approved by the City of Renton. Use of herbicides or pesticides within the mitigation area would only be implemented if other measures failed or were considered unlikely to be successful, and would require prior agency approval (C & M). 7. Clean-up trash and other debris within the mitigation areas on a twice-yearly basis (M). 8. Selectively thin and prune woody plants to meet the mitigation plan's goal and objectives (e.g., removal of dead or diseased portions of trees/shrubs and thinning of volunteer trees such as red alder) (M). 13.0 PERFORMANCE BOND A performance bond will be posted with the City of Renton by the property owner for the cost of replacement of plantings and the five-year monitoring plan to assure the success of the mitigation plan. The bond may be released in partial amounts in proportion to work successfully completed over the monitoring period as the applicant demonstrates performance for implementing the conditions of the plan. 14.0 AS-BUILT PLAN Following completion of construction activities, an as-built plan for the wetland mitigation areas will be prepared and submitted to the City of Renton. The plans will identify and describe any changes in grading, planting or other constructed features in relation to the original approved plan. 15.0 SUMMARY AND CONCLUSION Four wetlands, Wetlands A, B, C, and D, were identified and delineated on site. Generally, on-site wetlands consist of palustrine, emergent, seasonally or temporarily flooded wetlands. Wetland A is a Category 3 wetland that qualifies for exemption under Renton's Code because it was artificially created on top of compacted fill material. Wetlands B and C are Category 3 wetlands and qualify for a size threshold exemption under the City's Code. Wetland D is a Category 2 wetland and would require a 50-foot buffer under the City of Renton Development Regulations. The proposed project would fill non-regulated wetlands. 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(24Oct02).doc Page 19 Buttar Property Wetland Study Report and Mitigation Plan Temporary impacts to the buffer of Wetland D will occur as a result of grading activities associated with the construction of required stormwater facilities. The Wetland D buffer will be restored at a 1:1 ratio. • • • • 24 October 2002 Talasaea Consultants,LLC 717-WIRpt4(24Oct02).doc Page 20 Buttar Property Wetland Study Report and Mitigation Plan 16.0 Refe rences Cooke, S. 2000.

PROJECT OVERVIEW The Buttar Property is located in the SW1/4 of Section 29, Township 23 North, Range 5 East, near the intersection of SE 172"a Street and Cedar Avenue SE in Renton, Washington (see Figure 1). Currently one parcel makes up the Buttar Property covering a total area of 9.52 acres. The parcel is occupied by one single-family residence and existing outbuildings. The entire property completely surrounds another existing 0.22acre single-family residence that will not be developed. The existingground cover is entirelyforested with a wetland in the southwestern portion of the site. The developer proposes to construct 50 new single-family residences with associated roadway and utilities. The existing house along with the outbuildings will be demolished. The residents will access via SE 172nd Street. The City of Renton requires Level 2 Flow Control and Basic Water Quality for the site. The on-site generated runoff will be directed to a combination detention/water quality pond. All drainage discharging from the pond will flow to the existing wetland located in the southwest corner of the site. i - 0 6 a EX COW"10AI N °' CEDAR AVE SE R r A `3 174thS' r%j (-- 0 0 .

OFFSITE ANALYSIS Upstream Tributary Area Offsite flows enter the eastern edge of the Buttar Property at two separate locations. These flows are labeled on Figure 2 as Up-1 and Up-2. Downstream Analysis Drainage from the site naturally sheet flows west across the property to the wetland located in the southwest corner of the parcel. Currently, this wetland discharges west into a ditch. The ditch becomes a moderately steep ravine for about 30',but transitions to a 5' wide by 3' deep channel. From here, water flows under the north end of Morris Avenue in an 18"CMP culvert. The drainage then enters another similar channel and continues 'i west to Talbot Road where it will eventually reach the Panther Creek wetland area. There is no evidence of erosion or overflow problems along the entire length of the downstream flowpath, with one exception. The 30' stretch of ravine previously mentioned appears to be the result of stormwater erosion. However,preliminary plans for the Sunnybrook Plat show this area will be developed into a detention pond, completely --' erasing the ravine and any concerns of ongoing erosion. See Figure 5 -Developed Site Hydrology, taken from the ESM Consulting Engineers Preliminary Drainage Report for the Sunnybrook Subdivision dated March 4, 2002. Up-1, the offsite flow mentioned earlier, is currently captured on the eastern edge of the property by a ditch and conveyed to the southeast edge of the site. Here Up-1 is joined by another offsite flow,Up-2. Both flows enter a 40' long, 18" culvert and travel under a gravel roadway, eventually discharging into a ditch. The ditch runs along the southern site boundary for approximately 250' and continues southwest onto the adjoining parcel. Within 800' the flow discharges into a nearby wetland. The wetland drains west to a 24in culvert that runs through an easement to Morris Avenue. From here the drainage turns south to South 38th Street, and then to the west across Talbot Road. Eventually the flows will reach the Panther Creek wetland area. Refer to Figure 2 for a map of the downstream flow paths described above. • iJ 1�� ! j. 1 // k S ; �••� .1w n:p.r. a __. i,` �9%m r� i — w g `��_ n 1 •• it�!16:T • •• • P -Ul. a aa1411ei, eu OA` , t--: Z ` 4 --317 a - Q 3 3.39 Ar w lill.i',4'FJ"�r ,1• \ 'if•'E' gs_'1 mo '�ro p �.,, 1 „I iiiii -`. . „II wfcE .Ee _iTy IN \ F' 6 ikL� E— eo•.

Hydraulic Analysis The drainage analysis was modeled using the King County Runoff Time Series (KCRTS) software. The site soils are Alderwood (AgC), KCRTS group, Till. The site is located in the Sea-Tac rainfall region with a location scale factor.of 1.0. See the attached soils map for the Renton Quadrangle and copies of pages 3-25 and 3-22 from the 1998 King County Storm Water Drainage Manual (KCSWDM). EXISTING CONDITIONS The Buttar property is 9.52 acres. However, 1.72 acres of wetpond and wetland area will not be detained and the parcel completely surrounded by our property will add 0.22 acres of tributary area. This results in 8.02 acres of developed area routed through the detention pond. Currently one house occupies the parcel along with existing outbuildings. The existing ground cover is a combination of impervious surfaces and till- forest. The zoning for the site is R-10, or 10 DU/AC. Per Table 3.2.2.E in the 1998 KCSWDM, the effective impervious fraction for>4 DU/AC is 0.80. The impervious area for the existing site is 0.11 acre. The effective impervious area is 0.80*0.11 acre=0.09 acre. The following information was used by KCRTS for generating time series and flow frequencies.

Where outwash soils are saturated or underlain at shallow depth (<5 feet) by glacial till,they should be treated as till soils. 2. These are bedrock soils,but calibration of HSPF by King County ON1R shows bedrock soils to have similar hydrologic response to till soils. 3. These are alluvial soils,some of which are underlain by glacial till or have a seasonally high water .- table. In the absence of detailed study,these soils should be treated as till soils. . 4. Buckley soils are formed on the low-permeability Osceola mudflow. Hydrologic response is _ assumed to be similar to that of till soils. , — 1998 Surface Water Design Manual 9/1/98 v , 3-25 _ SECTION 3.2 RUNOFF COMPUTATION AND ANALYSIS METHODS FIGURE 3.22.A RAINFALL REGIONS AND REGIONAL SCALE FACTORS ST 1.0/ ST 1.0 LA0.8 LA0.8 LA 1.0 LA 1.2 ST1.1 - .', SNONOYISN COONTr tiz J.OiN5>- .....1 ti„ •'.pia •1'$'.'1.%.

No newly developed flow will be added to the offsite flow. As a result, this flow will not be detained or treated for water quality. The offsite flow will exit the property approximately 220' from the southeastern property line, into its existing natural channel. The developed site will consist of 50 new single-family residences with associated access - roadways and utilities. The impervious area was calculated using the 1998 City of Renton Development Regulations (refer to page 18 of Chapter 2's Development Standard's for Residential Zoning, R-10). The maximum impervious surface per lot is 75% of the total lot area. All other impervious surfaces were measured by planimeter. The total lot area is assumed to be equal to the total detained area less the impervious area associated with the roads, less the pervious area associated with the open space, and less the area labeled"exception"on Figure 3. The total lot coverage is 8.02 acres— 1.64 acres — 1.08acres—0.22 acres= 5.08 acres. The maximum impervious surface for all the lots is 75%*5.08 acres=3.81 acres or 165,964 square feet. The average impervious coverage for each lot is 165,964/50=3,319 square feet.

SUMMARYIOF ACTION: Development Services Recommendation:Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on May 13, 2003. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application, field checking the property and surrounding area; the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the May 20,2003 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,May 20,2003, at 9:05 a.m. in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Preliminary Plat Plan application,proof of posting,proof of publication and other documentation pertinent to this request. Exhibit No.3: Neighborhood Vicinity Map Exhibit No.4: Zoning Map Exhibit No. 5: Coal Mining Area Map Exhibit No. 6: Sensitive Areas Map Exhibit No.7: Hazard Areas Map from Sunnybrook Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 2 The hearing opened with a presentation of the staff report by Leslie Nishihira, Senior Planner,Development Services, City of Renton, 1055 S Grady Way,Renton, Washington 98055. The proposal is to subdivide a 9.9- acre site into 50 lots intended for the development of detached single-family homes. The property is located in the southern portion on the City in the Talbot Hill area,abutting the division line between the City of Renton and King County. Surrounding the site are existing developments to the northeast under R-8 zoning, directly north are some undeveloped properties,zoned R-8, south are properties zoned R-10 and R-8,most recently the Sunnybrook plat was approved. There are coal mine hazardous areas that need to be avoided. The project was reviewed by the Environmental Review Committee(ERC)who issued a Determination of Non- Significance Mitigated(DNS-M). The DNS-M included twenty mitigation measures. There were no appeals filed. Measure one requires the project to comply with the recommendations contained within the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report,Measure two through five deal with temporary erosion control,measure six prohibits the placement of any structures,utilities,roadways within the designated high hazard areas,measure seven requires installation of a permanent fence surrounding the high hazard area, including signage at visible locations,measures eight and nine require informing future property owners of the coal mine hazard notice,measures ten and eleven require the applicant to comply with the 1998 King County Surface Water Drainage Manual with regard to flow control and the tight line drainage system, measure twelve requires the applicant to comply with the Wetland Study Report and Mitigation Plan,measure thirteen through fifteen requires the installation of silt fencing,permanent signage and fencing and a Native Growth Protection Easement to protect the wetlands,measures sixteen,nineteen and twenty were the standard fire,traffic and parks mitigation fees, and measures seventeen and eighteen requires a minimum 20' for all access roadways and that the applicant will provide the necessary means of access to serve the development. The proposal was routed to various City sections for review, comments have been incorporated into the Staff Report. The subject site is designated Residential Options on the Comprehensive Plan Land Use Map. The RO designation is designed to create new planned neighborhoods that include single family and multi-family developments. The proposal complies with infill development and RO policy LU-53 and LU-55. With respect to the underlying zoning designation,the density after deduction of the preserved wetland area, high coal mine hazard area,rights-of-way and private street easements the total 122,219 square feet of area,the resulting net acreage is 7.11 acres which results in a density of 7.03 dwelling units per acre which is just within the minimum range required. The proposal contains 100%of detached dwelling units,which is permitted in the R-10 zone. All lots comply with the minimum width, depth and area requirements. Two tracts are proposed in the project, Tract A, on the western portion of the site is 21,055 square feet and would contain the wetland and storm drainage areas. Tract B, in the north central portion of the property is approximately 33,825 square feet and would contain the High Mine Hazard Area. All lots,with the exception of 35 and 50,meets all front,rear and side yard setback requirements. Setbacks for these two lots do need to be corrected prior to recording the plat. Discussion ensued regarding portions of land adjoining lots 43,47 and 1 as to who would be responsible for their care and maintenance. They need to be included with the various lots or made a separate tract. The homeowners should be responsible,or the adjacent lots should have ownership of these parcels. • Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3, 2003 Page 3 There are existing structures on the property, including a single-family residence and detached accessory buildings. Staff recommends that these be demolished prior to recording of the plat. Side lot lines are at right angles to street lines and are configured in a manner most suited to the existing topography of the site.All lots,with the exception of 3, 7, 8, 9, 10, 13, 14, 34, 35,36,40,41, 42,45,46, 47, and 48 would have direct frontage to a newly created public roadway. The above exceptions would be serviced by private access drive easements proposed at 26 feet in width with 20 feet of paving. Staff has made additional recommendation requiring that the lots depicted on the plan meet all requirements for private roadways. Primary access to the site is proposed via an extension of a roadway that would be constructed as part of the Sunnybrook plat(proposed Road B)and would terminate at the northern property line. Extending eastward off Road B would be proposed Road A,bisecting the center portion of the site and connect to a secondary access point that is presently unimproved. This portion of Cedar Avenue is of substandard width and only includes 26 feet of roadway area with no paving. The project will be required to provide the appropriate paving width and turning radius for emergency access vehicles. The strip of land is not a dedicated right-of-way at this point. The public roads are proposed at reduced widths of 42 feet and would include 32 feet of paving along with curb, gutter,five-foot sidewalks and street lighting. The sidewalks are provided on both sides for Road A and B and are also included on the plan for the secondary access point on the northeast corner to the county roads. Staff recommends placement of permanent signage at the very northern end of Road B, indicating that at some point this road may be extended further north. Pedestrian linkage to the road that is part of the Sunnybrook project and further to Talbot road is required. The topography of the site slopes down from east to west with average slope of approximately 12% across the property. The site is located in areas designated with potential coal mine hazards based on the City's Sensitive Area's Maps. It also contains slopes between 15-25%. Site is predominately vegetated with grasses and blackberries as well as cotton wood,maple, cedar,and pine trees,most of which would be removed during site preparation. ''Earthwork is estimated at 5,000 cubic yards of cut and fill. At completion, 60%of the site is estimated to be covered with impervious areas. The geotechnical report concludes that the site is suitable for the development provided that they comply with recommendations contained within that report. In addition, specific erosion control measures have been required by staff during the construction of plan improvements in individual building lots. It has been learned that the Springbrook II Mine underlies the site and dips at a very steep angle, approximately 61 degrees down to the south. There are also three back-filled mine openings in the north-central portion of the site. The report concludes that the Springbrook II Mine is substantially collapsed and there is no manifestation of regional ground substenance on the site. There is a high hazard area in the north-central portion of the property in Tract B. There are no low or medium hazard areas identified. SEPA required applicant to install split rail fencing around the High Hazard Area within Tract B. The subject site is surrounded by predominately single-family residences, in the north there is some undeveloped property, and south there is the Sunnybrook proposal that will include all detached dwelling units. Within King County;just east of the project, are some apartments. Police,Fire,Recreation and the School District all indicated that provided that the applicant pay the required mitigation fees they could provide services to the proposed development. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 4 The applicant proposes to collect offsite flows near the eastern edge and reroute it to the site in a tight line drainage system underneath proposed Road A. This will exit the site approximately 22 feet from the southeastern property line into its existing drainage channel. No detention or water quality treatment is required. On site run off will be directed to a combination detention water quality pond and will discharge to the existing wetland in the southwest corner of the site. Staff requires that it comply with the 1998 Manual with SEPA conditions. Staff recommends as a condition of plat approval that the applicant be required to establish a Homeowners Association or Maintenance Agreement for common utility and roadway improvements included in the project. The wetlands map was made Exhibit 6, Sensitive Areas. There are four wetlands on the site. The wetland A was formed on top of fill legally placed on the property,the wetland hydrology is solely provided by the compaction of the soil and fill materials, and that the US Army Corp of Engineers will not take jurisdiction over the wetland. Wetland B and C are classified as category 3,both less than 5,000 square feet, and are permitted to be filled. Wetland D is a category 2 Emergent Wetland, as such it requires a minimum buffer within 50 feet. The City of Renton and The Soos Creek Water and Sewer districts serve the site. The applicant needs to contact Soos Creek Sanitary Sewer District for availability. In conclusion, staff recommends approval of the Cedar Avenue Preliminary Plat subject to conditions listed in the Staff Report. Lafe Hermansen, Core Design, 14711 NE 29th Place, Suite 101,Bellevue, WA 98007 stated that sewer and water availability have been applied for. Soos Creek has been contacted and they are awaiting an answer. Tract B,the intention of the division was to create a green space along the road,there is a view of the valley and mountains, also with the potential of a tot lot or something that would be secluded on that side of the street. The area around the High Coal Mine Hazard area is intended to be a grassy area with some trees. The area adjacent to Lot 47,the property owners have an option to purchase this land, so the strip in question could be added into a lot in the future. It will be included in Lot 47. The long skinny piece of property that runs north/south adjacent to Lot 1,we didn't know what the City was going to want to do with it, it was never a right-of-way to the County. It was thought to create an access trail through there to be maintained by the Homeowners Association. The Examiner asked if there was a coal mine hazard in that area. Ms.Nishihira responded that a hazard area is designated in the southern corner. Rob Stevens, Core Design, 14711 NE 29th Place, Suite 101,Bellevue, WA 98007, civil engineer on the project and responsible for the storm drainage design. Regarding concerns of the wetlands being filled and how they were being compensated for in the detention facility. The wetlands were created by the coal mining activities, they are relatively created areas on sloped areas. The conditions used for the site are forested conditions,which are more conservative that actual wetlands. The detention facility has sized for the King County 1998 Manual Level 2 criteria. Neil Watts,Director Development Services, 1055 South Grady Way,Renton, WA 98055, stated that this site can be very confusing in terms of what we visualize wetlands being. Typically they are ponds and places where ducks reside, looking closely at the location of the larger wetland, it is on a fairly steep slope. Basically you have land that is wet versus the typical swamp or pond. Using forested pre-existing conditions is more conservative method of sizing for the new pond that being treated as a wetland. Regarding the piece of property running adjacent to Lot 1,there is no evidence that that strip was ever dedicated to the County or the City, it appears that it is still a piece of this parcel. The Administration's preference is that this remains as private property. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 5 Oliver Grah, Talasae Consultants,LLC, 15020 Bear Creek Road NE,Woodinville, WA 98072, commented that Wetland A,by the nature of its landscape position and the shape of the land form there, has very low storm water detention capacity,the loss of that wetland would not represent substantive increase in storm water runoff from the site. The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff. The hearing closed at 10:05 a.m. FINDINGS, CONCLUSIONS &RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: FINDINGS: 1. The applicant, Dr.Baljinder and Rashpal Buttar, filed a request for approval of a 50-lot Preliminary Plat together with two tracts. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA) documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non-Significance-Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is at 3521 Cedar Avenue South. The subject site is located southwest of SR-515 and north of Carr Road. Talbot Road South is located east of the subject site. 6. The subject site was annexed to the City with the adoption of Ordinance 4476 enacted in October 1994 (the staff report indicated the year was 1974). 7. The subject site is zoned both R-10(Residential Options permitting single family and attached housing). 8. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of residential options including detached single family and multiple family uses, but does not mandate such development without consideration of other policies of the Plan. 9. The subject site is approximately 9.9 acres or 432,069 square feet. The subject site is a generally rectangular parcel that is approximately 332 feet wide(north to south)by 1,318 feet long. A third-party property,not part of the proposal, is located near the northeast corner of the subject site and is surrounded by the subject site on the north,west and south. It has a long narrow panhandle at its southeast corner that is approximately 30 feet wide(east to west)by 280 feet long. The panhandle has been described as an unopened right-of-way but title and record searches did not find any dedication or assignment to the public. (see below) 10. The site slopes downward from the east to the west approximately 140 feet or approximately 12%. The property drops in three stages or locations with the eastern third dropping approximately 8%to 15%,the central portion dropping approximately 18%to 27% and the western portion dropping approximately 8%. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 6 11. The site contains both wetland areas and high hazard coal mine areas. Three wetlands were determined to be unregulated and will be filled and developed. These are a small Wetland B (1,275 square feet) in the northwest corner of the site, a small Wetland C(740 square feet) in the southeast corner of the site and large Wetland A((12,211 square feet)in the center of the site. All are Category 3 wetlands. 12. Wetland D is a Category 2 wetland located in the western portion of the site. The wetland is approximately 59,138 square feet with approximately 28,572 square feet located on the subject site. This wetland would be preserved and requires a 50-foot wide buffer. The applicant's preparation of the site for development would disturb approximately 6,700 square feet of buffer area for this wetland. It would be restored after the needed work is complete. An exemption was granted to allow this work. In addition, an exemption will allow storm water to be discharged into the wetland and to allow storm water management facilities to be installed in the buffer but not the wetlands. 13. The coal mine area is located in the north central area of the site. The area is approximately 350 feet long(east to west)by 75 feet wide. This area will be left undeveloped and an area just north of it will also be left undeveloped since access to it would be difficult. Fencing will identify the area and signs will be installed to warn of potential danger in the area. 14. The subject site is covered by grasses,blackberries and some larger Cottonwood,Maple,Cedar and Pine trees. Most of the trees and smaller vegetation will be removed to allow the dense development permitted in the R-10 zone. The vegetation in the sensitive coal mine and wetland areas will be retained. 15. An existing home and outbuildings are located near the northeast corner of the subject site. 16. The applicant proposes dividing the property into 50 lots. In addition,the applicant proposes two larger tracts near the wetland in the west to contain storm water and north of the coal mine area in the center of the property, as well as some smaller landscaped or open space parcels in areas too small to contain building lots. One is east of the coal mine area, another is a narrow strip in the furthest northeast corner of the parcel and the third is the panhandle segment in the southeast corner of the plat. There would also be wetland and coal mine areas. 17. The applicant proposes developing the fifty lots with detached single-family homes although the R-10 would allow a mix of detached and attached dwelling units. 18. Most of the homes would be located north and south of a new road that would run west to east across the middle of the plat. This new road would be the primary access. It will connect on the west with a new north-south road that would extend from a roadway being developed by the recently approved Sunnybrook plat. At its eastern end the east-west road would swing north and connect to Cedar Avenue,which would serve as a secondary access. Cedar is a narrow substandard connection. 19. Lots would be aligned north and south of the primary access road in single, double and triple stacked lots. That is there would be a series of interior or internal lots that would not front directly on a road but would be accessed by an easement roadway. These interior lots will be constrained in size and surrounded on three or four sides by other homes. These interior lots would be very hemmed in by this development pattern. 20. There will be five easement roadways providing access to 18 interior lots,Lots 3, 7-10, 13, 14, 34-36, 40-43 and 45-48. In addition, staff recommended that the lots that have road frontage on both the public • Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 7 roadway and these private easements use the easements for access in order to reduce the number of curb cuts on the public right-of-way. The lots affected by this recommendation would be lots 6, 11, 12, 33, 37,44 and 49. 21. The westernmost,north-south road would be stubbed at the north property line of the subject site. This would eventually be extended to provide access to the property north of the subject site. Staff recommended that a sign be erected informing future residents that a through street is intended to be developed at that location. 22. The ERC required that the applicant provide both primary and secondary access roads to serve the development. This condition presupposes that if the adjacent Sunnybrook plat does not develop,that the applicant will still have to provide the necessary roads for access to the subject site. 23. The R-10 requires minimum lot sizes of 3,000 square feet for detached single-family homes. Lot width is 30 feet or 40 feet for corner lots and lot depth is 55 feet. The proposed lots vary from 3,600 square feet to 5,750 square feet. Lot width will vary from 35 feet to 55 feet and length will vary from 80 feet to 122 feet. 24. The applicant has specified the various yards for lots that front both public streets and the easement roadways. Proposed Lots 35 and 50 do not appropriately designate the appropriate front and rear yard setbacks. In addition, staff has noted that the lots are constrained by size and dimensions and that building pads for many of them should be oriented as noted in the following chart: Lot# Front Yard Rear Yard Side Yard Along Interior Side (10 feet) (15 feet) a Street(10 feet) Yard(s) (5 feet) 3 west property line east property line N/A north& south property lines 5 north property line south property line west property line east property line (exclusive of easmt) 6 east property line west property line north property line south property line (exclusive of easmt) 7 east property line west property line N/A north& south (exclusive of property lines easmt) 8 east property line west property line N/A north& south property lines 9 west property line east property line N/A north& south property lines 10 west property line east property line N/A north& south (exclusive of property lines easmt) 11 west property line east property line north property line south property line (exclusive of easmt) 12 east property line west property line north property line south property line (exclusive of easmt) Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 8 13 east property line west property line N/A north& south (exclusive of property lines easmt) 14 east property line west property line N/A north& south property lines 33 east property line west property line south property line north property line (exclusive of easmt) 34 east property line west property line N/A north& south (exclusive of property lines easmt) 35 east property line west property line N/A north & south (must be property lines corrected) 36 west property line east property line N/A north& south (exclusive of property lines easmt) 37 west property line east property line south property line north property line (exclusive of easmt) 40 east property line west property line N/A north& south (exclusive of property lines easmt) 41 east property line west property line N/A north & south property lines 42 west property line east property line N/A north& south property lines 43 west property line east property line N/A north& south (exclusive of property lines easmt) 44 east property line west property line south property line north property line (exclusive of easmt) 45 east property line west property line N/A north & south (exclusive of property lines easmt) 46 east property line west property line N/A north & south property lines 47 west property line east property line N/A north & south property lines 48 west property line east property line N/A north& south (exclusive of property lines easmt) 49 west property line east property line south property line north property line (exclusive of easmt) 50 east property line west property line south property line north property line (must be corrected) • Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 9 25. The development will increase traffic approximately 10 trips per unit or approximately 500 trips for the 50 single-family homes. Approximately 50 additional peak hour trips will be generated in the morning and evening. 26. The subject site is split between the Soos Creek Water and Sewer District and the City of Renton for water service. The two districts are working on the boundary. The site is entirely within the Soos Creek District for sanitary sewer. 27. The subject site is located within the Renton School District. The project is expected to generate approximately 22 school age children. These students would be spread across the grades and would be assigned on a space available basis. 28. The density for the plat would be 7.03 dwelling units per acre after subtracting sensitive areas(coal mine and wetland)and roadways. 29. There is R-8 zoning generally north,west and south of the site along Talbot Avenue South. R-10 is found south of the subject site. 30. As noted,the applicant proposes some common open space areas that would be under the control of a homeowners association. In one case the parcel is located south of Proposed Lots 40 and 43 in the center of the site. A private easement roadway would bisect the parcel. The second such parcel is located at the extreme northeast corner of the site east of Proposed Lot 47. It is approximately 30 feet wide and 150 feet long and is sandwiched between two third-party properties. The third area is that panhandle at the southeast corner of the site as well as a triangular remnant created by the curvature of the proposed road. The City does not want ownership of this parcel and due to coal mine hazards south of it, it cannot be used for permanent access. In addition, as noted above,Tracts A and B are adjacent and associated with the Wetlands and Coal Mine areas respectively. The panhandle could be traded or offered to the Sunnybrook development. CONCLUSIONS: 1. The proposed plat appears to satisfy the public use and interest. The proposed plat will provide a complement of small lot single family housing for those who do not want or need larger lots or homes. The disadvantage of this arrangement will be the large number of interior lots. Such lots may feel confined or hemmed in since they are surrounding by housing and possibly fences on all sides rather than an open streetscape. In addition,the easement access reduces the useful yard areas in some case but the lots do meet the various requirements of code. 2. The development of detached single-family uses on the R-10 parcel meets the policies and goals of the Comprehensive Plan. 3. The proposed plat provides for infill development in an area where urban services are available. The proposal also meets the required density, seven to ten units per acre, of the City. 4. The development should not tax either the road system or the existing utility infrastructure. The applicant will have to develop a road system in the plat and may have to develop roadways outside the plat if the Sunnybrook plat does not complete the necessary access roads. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3, 2003 Page 10 5. Development of the additional lots will increase the tax base of the City. The applicant has also been required to pay mitigation fees to offset its impacts on fire,parks and transportation systems. 6. Since a through road may be developed at the northwest corner of the plat where a stub road will be installed, staffs recommendation that a sign be posted is appropriate. 7. Since there may be unmapped coal mine areas outside of the known hazard areas,the applicant will be required to record restrictive covenants for the entire site that mirror those required by the ERC. 8. The common open space areas may create maintenance problems and the one adjacent to Proposed Lot 47 should be incorporated into that lot. The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook. The portions adjacent to Proposed Lot 1 should be incorporated into that lot if the remainder is conveyed. 9. The development of the subject site will create additional traffic. There will also be additional noise associated with larger population. These impacts should not create any undue impacts on the overall community and were anticipated when the Zoning and Comprehensive Plan were adopted. 10. In conclusion,the proposed plat appears reasonable and should be approved by the City Council. RECOMMENDATION: The City Council should approve the Preliminary Plat subject to the following conditions: 1. A covenant that addresses the approved density of the site and the dwelling unit mix approved with the plat shall be created concurrently with the recording of the plat.A draft of the document shall be submitted to the City of Renton Development Services Division for review and approval by the City Attorney and Property Services section prior to the recording of the plat. 2. The applicant shall revise the plat plan in order to provide the correct yard setbacks for lots 35 and 50. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 3. The applicant shall obtain a demolition permit and complete all necessary inspections and approvals for the existing detached structures to be removed from the property. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 4. The applicant shall indicate on the face of the plat the location and orientation of the front,rear and side yard setbacks for each of the lots as depicted on the approved plat plan and as referenced in the table included in the staff report. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 5. The lots which front both the public roadway and a private street(lots 5, 6, 11, 12, 33, 37,44, and 49) shall utilize the abutting private street for driveway access and shall not be served directly off of the public roadway. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the issuance of the construction permits for the installation of roadway improvements for the development. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3, 2003 Page 11 6. The applicant shall install permanent signage at the north end of public roadway"B"which indicates the roadway may be extended at a future date. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 7. A homeowner's association or maintenance agreement shall be created concurrently with the recording of the plat in order to establish maintenance responsibilities for all shared improvements within this development. A draft of the document(s), if necessary, shall be submitted to the City of Renton Development Services Division for review and approval by the City Attorney and Property Services section prior to the recording of the short plat. 8. The applicant shall comply with the conditions imposed by the ERC. 9. The applicant shall provide a turnaround acceptable to the Fire Department. The turnaround can be abandoned or dismantled once adequate through or looped circulation is provided by development of adjacent properties. 10. Since through roads are anticipated from the new access road, signs should be posted that prominently note that the stubs or cul-de-sac will eventually create a roadway or roadways with through traffic. 11. The applicant shall be required to record restrictive covenants that mirrorthose required by the ERC for the entire site regarding coal mine hazards. 12. The common open space areas may create maintenance problems and the one adjacent to Proposed Lot 47 should be incorporated into that lot,unless conveyed to a third-party ownership. The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook. The portions adjacent to Proposed Lot 1 should be incorporated into that lot if the remainder is conveyed. 13. The applicant shall obtain the necessary"will serve"written confirmation that both domestic water and sanitary sewer services are available to serve the plat. ORDERED THIS 3rd day of June,2003.

The Appearance of Fairness Doctrine provides that no ex parte(private one-on-one)communications may occur concerning pending land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. wl 5' ° !l I..I I — I .,,,,,,,.µ,1201r.”...-`,"''''''''.7., "7,.."'

III Preliminary Plat (aka Piele Preliminary Plat). The requested revisions have been determined*to be a "minor" amendment and has been approved subject to condition. The City Council approved the preliminary plat on November 4, 2002 with conditions as recommended by the Hearing Examiner. The approved plat plan includes 22 residential lots. PROPOSED AMENDMENT The request is to modify the approved plat plan in order to address a recently approved lot line adjustment(LUA 03-123 LLA)which impacted the subject plat's boundary and lot area. The applicant is proposing to: . 1) modify the plat boundary abutting new Lot 1 and new Lot 6 as affected by the lot line adjustment; . 2) modify lot sizes for new Lot 1 ( old - 8,853 sq.ft. to new-10,624 sq. ft.) and Lot 6 (old —9,626 sq. ft. to new—6,164; and, 3) Density would slightly increase to'7.07 du/ac due to change in plat area. ANALYSIS The subdivision regulations allow for the applicant to.request an amendment to an 'approved or conditionally approved plat at any time after preliminary plat approval and before final plat approval (RMC 4-7-080.M). This provision also establishes that a proposed amendment is "minor" if it does not - fall within the definitions of a "major"amendment as listed below: a. Any amendment that would result in or would have the effect of decreasing the aggregate area of open space in the subdivision by ten percent(10%) or more; b. Any amendment that would result in increasing the number of lots in the subdivision beyond the number previously approved; c. Any amendment that would result in the relocation of any roadway access point to an exterior street from the plat; d. Any amendment that proposes phasing of plat development; e. Any amendment that, in the opinion of the Administrator, would significantly increase any adverse impacts or undesirable effects of the plat;or, f. Any amendment that would result in or have the effect of reducing the residential dwelling unit density for the site below the allowed minimum density. 1055 South Grady Way-Renton,Washington 98055 R E N Y 0 N AHEAD OF THE CURVE a, This paper contains 50%recycled material,30%post consumer • CITY IF RENTON Plannin uildin blicWorks Department Kathy Keolker.Wheeler, Mayor Gregg Zimmerman P.E.,Administrator July 26, 2004 Lafe Hermansen Core Design, Inc. 14711 NE 29th PL, Suite#101 Bellevue, WA 98007 Subject: Minor Amendment to Honey Brooke Div.

The amendments to the revised plat have been determined to comply with the following: • The underlying zoning designation of Residential — 8 (R-8) including lot dimensions, lot sizes and access requirements; • density would slightly increase from 6.91 du/ac to 7.07 du/ac (the maximum,is 8.0 du/ac) (192,411 sq. ft.

This is due to the Lot Line Adjustment that occurred reducing the overall property size. The City would like clarification that the site still meets the requirements for the R-8 zone. Please consider this letter our formal request for a minor amendment to the Honey Brooke Division III Preliminary Plat. The site density and lot sites still meet all City of Renton requirements. The revised net density for the property is 7.07 D.U./Acre. The corner lots are all 60'wide and all interior lots meet the 50'minimum lot width. All lots are over the minimum lot size of 4,500 S.F. Please find attached to this letter the revised City of Renton Density Calculation sheet. We trust that this letter will satisfy the City of Renton's request.

The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook: The portions • adjacent, to Proposed Lot 1 should be incorporated into that lot if the remainder is Conveyed. The proposed amendment is described as follows: The applicant is proposing to delete what was Lot 44 and shift Lot 50 to the 30 ft. wide flag east of Lot 47. A lot line adjustment is proposed for new Lot 50 and the abutting lot (outside of plat limits) to make a wider lot. Also, the applicant is proposing revisions to the land area next to Proposed Lot 1. During the preliminary plat process, this 30.ft.'wide strip was believed to be part of the property. It has since been determined that the. 30,ft. wide strip east of lot 1 is actually dedicated right-of-way.

This provision also establishes that a proposed amendment is "minor" if it does not fall within the definitions of a "major" amendment as listed below: a. Any amendment that would result in or would have the effect of decreasing the aggregate area of open space in the subdivision by ten percent (10%)or more; b. Any amendment that would result in increasing the number of lots in the subdivision beyond the number previously approved; c. Any amendment that would result in the relocation of any roadway access point to an exterior street from the plat; d. Any amendment that proposes phasing of plat development; e. Any amendment that, in the opinion of the Administrator, would significantly increase any adverse impacts or undesirable effects oftheplat; or, f. Any amendment that would result in or have the effect of reducing the residential dwelling unit density for the site below the allowed minimum density. The proposed modifications would not: a) decrease the amount of open space by 10% or more; b) result in an increased number of lots; c) substantially relocate a roadway access point to an exterior street; d) include phasing; or e) result in a significant increase of adverse impacts from the plat. The amendments would address the Hearing Examiner condition for proposed Lots 1 and 47 and thus meet the requirement. The revised plat has been determined to comply with: ■ The underlying zoning designation of Residential — 10 (R-10) (RMC 4-2-110.F) including meeting density, lot dimension and size and access requirements; and ■ The Subdivision Regulations (RMC 4-7-080). DECISION The proposed minor amendments to the conditionally approved preliminary plat have been approved as presented, subject to the following condition. 1. The applicant shall submit an updated PMT (photo mylar transfer) 8 1/2 x 11 reduction of the plat plan prior to final recording of the plat. In addition, the applicant is advised that all code requirements, conditions of the preliminary plat approval and mitigating measures of the SEPA review remain applicable to the development of the site. This decision to approve the proposed modification as a minor amendment to the preliminary plat is subject to a fourteen (14) day appeal period from the date of the this letter. Any appeals of the administrative decision must be filed with the City of Renton Hearing Examiner by 5:00 p.m. on May 6, 2004.

STAFF RECOMMENDATION: Staff recommends approval of the Cedar Avenue Preliminary Plat, subject to conditions. . June 3, 2003 OFFICE OF THE:HEARING EXAMINER CITY OF RENTON REPORT AND RECOMMENDATION APPLICANT: Dr.Baljinder&Rashpal Buttar 4501 NE 4th Street, Suite A Renton,WA 98056 Cedar Avenue Preliminary Plat File No: LUA-02-125,PP,ECF LOCATION: 3521 Cedar Avenue South SUMMARY OF REQUEST: Subdivide a 9.9-acre site into 50 lots for the construction of detached single-family residences. SUMMARY OF ACTION: Development Services Recommendation:Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on May 13, 2003. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application,field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the May 20,2003 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,May 20,2003,at 9:05 a.m.in the Council Chambers on the seventh floor of the Renton City Hall. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Preliminary Plat Plan application,lproof of posting,proof of publication and other documentation pertinent to this request. Exhibit No.3: Neighborhood Vicinity Map Exhibit No.4: Zoning Map Exhibit No:5: Coal Mining Area Map Exhibit No.6: Sensitive Areas Map Exhibit No:7: Hazard Areas Map from Sunnybrook Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 2 The hearing opened with a presentation of the staff report by Leslie Nishihira, Senior Planner, Development Services, City of Renton, 1055 S Grady Way,Renton,Washington 98055. The proposal is to subdivide a 9.9- acre site into 50 lots intended for the development of detached single-family homes. The property is located in the southern portion on the City in the Talbot Hill area, abutting the division line between the City of Renton and King County. Surrounding the site are existing developments to the northeast under R-8 zoning, directly north are some undeveloped properties, zoned R-8,south are properties zoned R-10 and R-8,most recently the Sunnybrook plat was approved. There are coal mine hazardous areas that need to be avoided. The project was reviewed by the Environmental Review Committee(ERC)who issued a Determination of Non- Significance Mitigated (DNS-M). The DNS-M included twenty mitigation measures_ There were no appeals filed. Measure one requires the project to comply with the recommendations contained within the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report,Measure two through five deal with temporary erosion control,measure six prohibits the placement of any structures,utilities,roadways within the designated high hazard areas,measure seven requires installation of a permanent fence surrounding the high hazard area, including signage at visible locations,measures eight and nine require informing future property owners of the coal mine hazard notice,measures ten and eleven require the applicant to comply with the 1998 King County Surface Water Drainage Manual with regard to flow control and'the tight line drainage system, measure twelve requires the applicant to comply with the Wetland Study Report and Mitigation Plan,measure thirteen through fifteen requires the installation of silt fencing,permanent signage and fencing and a Native Growth Protection Easement to protect the wetlands,measures sixteen,nineteen and twenty were the standard fire,traffic and parks mitigation fees, and measures seventeen and eighteen requires a minimum 20' for all access roadways and that the applicant will provide the necessary means of access to serve the development. The proposal was routed to various City sections for review,comments have been incorporated into the Staff Report. The subject site is designated Residential Options on the Comprehensive Plan Land Use Map. The RO designation is designed to create new planned neighborhoods that include single family and multi-family developments. The proposal complies with infill development and RO policy LU-53 and LU-55. With respect to the underlying zoning designation,the density after deduction of the preserved wetland area, high coal mine hazard area,rights-of-way and private street easements the total 122,219 square feet of area,the resulting net acreage is 7.11 acres which results in a density of 7.03 dwelling units per acre which is just within the minimum range required. The proposal contains 100%of detached dwelling units,which is permitted in the R-10 zone. All lots comply with the minimum width,depth and area requirements. Two tracts are proposed in the project, Tract A,on the western portion of the site is 21,055 square feet and would contain the wetland and storm drainage areas. Tract B, in the north central portion of the property is approximately 33,825 square feet and • would contain the High Mine Hazard Area. All lots,with the exception of 35 and 50,meets all front,rear and side yard setback requirements. Setbacks for these two lots do need to be corrected prior to recording the plat. Discussion ensued regarding portions of land adjoining lots 43,47 and 1 as to who would be responsible for their care and maintenance. They need to be included with the various lots or made a separate tract. The homeowners should be responsible,or the adjacent lots should have ownership of these parcels. Cedar Avenue Preliminary Plat File No.: I!UA-02-125,ECF,PP June 3,2003 Page 3 There are existing structures on the property, including a single-family residence and detached accessory buildings. 'I Staff recommends that these be demolished prior to recording of the plat. Side lot lines are at right angles to street lines and are configured in a manner most suited to the existing topography of the site.All lots,with the exception of 3,7, 8,.9, 10, 13, 14,34,35,36,40,41,42,45,46,47, and 48 would have direct frontage to a newly created public roadway. The above exceptions would be serviced by private access drive easements proposed at 26 feet in width with 20 feet of paving. Staff has made additional recommendation requiring that the lots depicted on the plan meet all requirements for private roadways. Primary access to the site is proposed via an extension of a roadway that would be constructed as part of the Sunnybrook plat(proposed.Road B)and would terminate at the northern property line. Extending eastward off Road B would be proposed Road A,bisecting the center portion of the site and connect to a secondary access point that is presently unimproved. This portion of Cedar Avenue is of substandard width and only includes 26 feet of roadway area with no paving. The project will be required to provide the appropriate paving width and turning radius for emergency access vehicles. The strip of land is not a dedicated right-of-way at this point. The public roads are proposed at reduced widths of 42 feet and would include 32 feet of paving along with curb, gutter,five-foot sidewalks and street lighting. The sidewalks are provided on both sides for Road A and B and are also included on the plan for the secondary access point on the northeast corner to the county roads. Staff recommends placement of permanent signage at the very northern end of Road B,indicating that at some point this road may be extended further north. Pedestrian linkage to the road that is part of the Sunnybrook project and further to Talbot road is required. The topography of the site slopes down from east to west with average slope of approximately 12% across the property. The site is located in areas designated with potential coal mine hazards based on the City's Sensitive Area's Maps. It also contains slopes between 15-25%. Site is predominately vegetated with grasses and blackberries as well as cotton wood,maple,cedar,and pine trees,most of which would be removed during site preparation. Earthwork is estimated at 5,000 cubic yards of cut and fill. At completion, 60%of the site is estimated to be covered with impervious areas. The geotechnical report concludes that the site is suitable for the development provided that they comply with recommendations contained within that report. In addition,specific erosion control measures have been required by',staff during the construction of plan improvements in individual building lots. It has been'learned that the Springbrook II Mine underlies the site and dips at a very steep angle, approximately 61 degrees'down to the south. There are also three back-filled mine openings in the north-central portion of the site. The report concludes that the Springbrook II Mine is substantially collapsed and there is no manifestation of regional',ground substenance on the site. There is a high hazard area in the north-central portion of the property in Tract B. There are no low or medium hazard areas identified. SEPA required applicant to install split rail fencing around the High Hazard Area within Tract B. The subject site is surrounded by predominately single-family residences, in the north there is some undeveloped property, and south there is the Sunnybrook proposal that will include all detached dwelling units. Within King County,just east of the project, are some apartments. Police,Fire,Recreation and the School District all indicated that provided that the applicant pay the required mitigation fees they could provide services to the proposed development. • d Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 4 The applicant proposes to collect offsite flows near the eastern edge and reroute it to the site in a tight line drainage system underneath proposed Road A. This will exit the site approximately 22 feet from the southeastern property line into its existing drainage channel. No detention or water.quality treatment is required. On site run off will be directed to a combination detention water quality pond and will discharge to the existing wetland in the southwest corner of the site. Staff requires that it comply with the 1998 Manual with SEPA conditions. Staff recommends as a condition of plat approval that the applicant be required to establish a Homeowners Association or Maintenance Agreement for common utility and roadway improvements included in the project. The wetlands map was made Exhibit 6, Sensitive Areas. There are four wetlands on the site. The wetland A was formed on top of fill legally placed on the property,the wetland hydrology is solely provided by the compaction of the soil and fill materials,and that the US Army Corp of Engineers will not take jurisdiction over the wetland. Wetland B and C are classified as category 3,both less than.5,000 square feet,and are permitted to be filled. Wetland D is a category 2 Emergent Wetland,as such it requires a minimum buffer within 50 feet. The City of Renton and The Soos Creek Water and Sewer districts serve the site. The applicant needs to contact Soos Creek Sanitary Sewer District for availability. In conclusion, staff recommends approval of the Cedar Avenue Preliminary Plat subject to conditions listed in the Staff Report. Lafe Hermansen,Core Design, 14711 NE 29th Place, Suite 101,Bellevue, WA 98007 stated that sewer and water availability have been applied for. Soos Creek has been contacted and they are awaiting an answer. Tract B,the intention of the division was to create a green space along the road,there is a view of the valley and mountains,also with the potential of a tot lot or something that would be secluded on that side of the street. The area around the High Coal Mine Hazard area is intended to be a grassy area with some trees. The area adjacent to Lot 47,the property owners have an option to purchase this land,so the strip in question could be added into a lot in the future. It will be included in Lot 47. The long skinny piece of property that runs north/south adjacent to Lot 1,we didn't know what the City was going to want to do with it,it was never a right-of-way to the County. It was thought to create an access trail through there to be maintained by the Homeowners Association. The Examiner asked if there was a coal mine hazard in that area. Ms.Nishihira responded that a hazard area is designated in the southern corner. Rob Stevens, Core Design, 14711 NE 29th Place, Suite 101,Bellevue,WA 98007,civil engineer on the project and responsible for the storm drainage design. Regarding concerns of the wetlands being filled and how they were being compensated for in the detention facility. The wetlands were created by the coal mining activities, they are relatively created areas on sloped areas. The conditions used for the site are forested conditions,which are more conservative that actual wetlands. The detention facility has sized for the King County 1998 Manual Level 2 criteria. Neil Watts,Director Development Services, 1055 South Grady Way,Renton,WA 98055, stated that this site can be very confusing in terms of what we visualize wetlands being. Typically they are ponds and places where ducks reside, looking closely at the location of the larger wetland,it is on a fairly steep slope. Basically you have land that is wet versus the typical swamp or pond. Using forested pre-existing conditions is more conservative method of sizing for the new pond that being treated as a wetland. Regarding the piece of property running adjacent to Lot 1,there is no evidence that that strip was ever dedicated to the County or the City, it appears that it is still a piece of this parcel. The Administration's preference is that this remains as private property. • Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 5 Oliver Grail,Talasae Consultants,LLC, 15020 Bear Creek Road NE,Woodinville,WA 98072, commented that Wetland A,by the nature of its landscape position and the shape of the land form there,has very low storm water detention capacity,the loss of that wetland would not represent substantive increase in storm water runoff from the site. The Examiner called for further testimony regarding this project. There was no one else wishing to speak,and no further comments from staff. The hearing closed at 10:05 a.m. FINDINGS,CONCLUSIONS &RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: FINDING'S: 1. The applicant,Dr.Baljinder and Rashpal Buttar,filed a request for approval of a 50-lot Preliminary Plat together with two tracts. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non-Significance-Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is at 3521 Cedar Avenue South. The subject site is located southwest of SR-515 and north of Carr Road. Talbot Road South is located east of the subject site. 6. The subject site was annexed to the City with the adoption of Ordinance 4476 enacted in October 1994 (the staff report indicated the year was 1974). 7. The subject site is zoned both R-10(Residential Options permitting single family and attached housing). 8. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of residential options including detached single family and multiple family uses,but does not mandate such development without consideration of other policies of the Plan. 9. The subject site is approximately 9.9 acres or 432,069 square feet. The subject site is a generally rectangular parcel that is approximately 332 feet wide(north to south)by 1,318 feet long. A third-party property,not part of the proposal, is located near the northeast corner of the subject site and is surrounded by the subject site on the north,west and south. It has a long narrow panhandle at its southeast corner that is approximately 30 feet wide(east to west)by 280 feet long. The panhandle has been described as an unopened right-of-way but title and record searches did not find any dedication or assignment to the public. (see below) 10. The site slopes downward from the east to the west approximately 140 feet or approximately 12%. The property drops in three stages or locations with the eastern third dropping approximately 8%to 15%,the central portion dropping approximately 18%to 27%and the western portion dropping approximately 8%. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 6 11. The site contains both wetland areas and high hazard coal mine areas. Three wetlands were determined to be unregulated and will be filled and developed. These are a small Wetland B (1,275 square feet)in the northwest corner of the site, a small Wetland C(740 square feet)in the southeast corner of the site and large Wetland A((12,211 square feet)in the center of the site. All are Category 3 wetlands. 12. Wetland D is a Category 2 wetland located in the western portion of the site. The wetland is approximately 59,138 square feet with approximately 28,572 square feet located on the subject site. This wetland would be preserved and requires a 50-foot wide buffer. The applicant's preparation of the site for development would disturb approximately 6,700 square feet of buffer area for this wetland. It would be restored after the needed work is complete. An exemption was granted to allow this work. In addition, an exemption will allow storm water to be discharged into the wetland and to allow storm water management facilities to be installed in the buffer but not the wetlands. 13. The coal mine area is located in the north central area of the site. The area is approximately 350 feet long(east to west)by 75 feet wide. This area will be left undeveloped and an area just north of it will also be left undeveloped since access to it would be difficult. Fencing will identify the area and signs will be installed to warn of potential danger in the area. 14. The subject site is covered by grasses,blackberries and some larger Cottonwood,Maple,Cedar and Pine trees. Most of the trees and smaller vegetation will be removed to allow the dense development permitted in the R-10 zone. The vegetation in the sensitive coal mine and wetland areas will be retained. 15. An existing home and outbuildings are located near the northeast corner of the subject site. 16. The applicant proposes dividing the property into 50 lots. In addition,the applicant proposes two larger tracts near the wetland in the west to contain storm water and north of the coal mine area in the center of the property,as well as some smaller landscaped or open space parcels in areas too small to contain building lots. One is east of the coal mine area, another is a narrow strip in the furthest northeast corner of the parcel and the third is the panhandle segment in the southeast corner of the plat. There would also be wetland and coal mine areas. 17. The applicant proposes developing the fifty lots with detached single-family homes although the R-10 would allow a mix of detached and attached dwelling units. 18. Most of the homes would be located north and south of a new road that would run west to east across the middle of the plat. This new road would be the primary access. It will connect on the west with a new north-south road.that would extend from a roadway being developed by the recently approved Sunnybrook plat. At its eastern end the east-west road would swing north and connect to Cedar Avenue,which would serve as a secondary access. Cedar is a narrow substandard connection. 19. Lots would be aligned north and south of the primary access road in single, double and triple stacked lots. That is there would be a series of interior or internal lots that would not front directly on a road but would be accessed by an easement roadway. These interior lots will be constrained in size and surrounded on three or four sides by other homes. These interior lots would be very hemmed in by this development pattern. 20. There will be five easement roadways providing access to 18 interior lots,Lots 3, 7-10, 13, 14,34-36, 40-43 and 45-48. In addition, staff recommended that the lots that have road frontage on both the public Cedar Avenue Preliminary Plat File No.:LUA-02-125,ECF,PP June 3,2003 Page 7 roadway and these private easements use the easements for access in order to reduce the number of curb cuts on the public right-of-way. The lots affected by this recommendation would be lots 6, 11, 12,33, 37,44 and 49. 21. The westernmost,north-south road would be stubbed at the north property line of the subject site. This would eventually be extended to provide access to the property north of the subject site. Staff recommended that a sign be erected informing future residents that a through street is intended to be developed at that location. 22. The ERC required that the applicant provide both primary and secondary access roads to serve the development. This condition presupposes that if the adjacent Sunnybrook plat does not develop,that the applicant will still have to provide the necessary roads for access to the subject site. 23. The R-10 requires minimum lot sizes of 3,000 square feet for detached single-family homes. Lot width is 30 feet or 40 feet for corner lots and lot.depth is 55 feet. The proposed lots vary from 3,600 square feet to 5,750 square feet. Lot width will vary from 35 feet to 55 feet and length will vary from 80 feet to 122 feet. 24. The applicant has specified the various yards for lots that front both public streets and the easement roadways. Proposed Lots 35 and 50 do not appropriately designate the appropriate front and rear yard setbacks. In addition, staff has noted that the lots are constrained by size and dimensions and that building pads for many of them should be oriented as noted in the following chart: Lot# Front Yard Rear Yard Side Yard Along Interior Side (10 feet) (15 feet) a Street(10 feet) Yard(s) (5 feet) 3 west property line east property line N/A north& south property lines 5 north property line south property line west property line east property line (exclusive of easmt) 6 east property line west property line north property line south property line (exclusive of easmt) 7 east property line west property line N/A north&south (exclusive of property lines easmt) 8 east property line west property line N/A north& south property lines 9 west property line east property line N/A north&south property lines 10 west property line east property line N/A north& south (exclusive of property lines easmt) 11 west property line east property line north property line south property line (exclusive of easmt) 12 east property line west property line north property line south property line (exclusive of easmt) Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 8 13 east property line west property line N/A north &south (exclusive of property lines easmt) 14 east property line west property line N/A north &south property lines 33 east property line west property line south property line north property line (exclusive of easmt) 34 east property line west property line N/A north &south (exclusive of property lines easmt) 35 east property line west property line N/A north &south (must be property lines corrected) 36 west property line east property line N/A north&south (exclusive of property lines easmt) 37 west property line east property line south property line north property line (exclusive of easmt) 40 east property line west property line N/A north & south (exclusive of property lines easmt) 41 east property line west property line N/A north & south property lines 42 west property line east property line N/A north&south property lines 43 west property line east property line N/A north&south (exclusive of property lines easmt) 44 east property line west property line south property line north property line (exclusive of easmt) 45 east property line west property line N/A north& south (exclusive of property lines easmt) 46 east property line west property line N/A north&south property lines 47 west property line east property line N/A north& south property lines 48 west property line east property line N/A north &south (exclusive of property lines easmt) 49 west property line east property line south property line north property line (exclusive of easmt) 50 east property line west property line south property line north property line (must be corrected) Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 • Page 9 25. The development will increase traffic approximately 10 trips per unit or approximately 500 trips for the 50,single-family homes. Approximately 50 additional peak hour trips will be generated in the morning and evening. 26. The subject site is split between the Soos Creek Water and Sewer District and the City of Renton for water service. The two districts are working on the boundary. The site is entirely within the Soos Creek District for sanitary sewer. 27. The subject site is located within the Renton School District. The project is expected to generate approximately 22 school age children. These students would be spread across the grades and would be assigned on a space available basis. 28. The density for the plat would be 7.03 dwelling units per acre after subtracting sensitive areas(coal mine and wetland)and roadways. 29. There is R-8 zoning generally north,west and south of the site along Talbot Avenue South. R-10 is found south of the subject site. 30. As noted,the applicant proposes some common open space areas that would be under the control of a homeowners association. In one case the parcel is located south of Proposed Lots 40 and 43 in the center of the site. A private easement roadway would bisect the parcel. The second such parcel is located at the extreme northeast corner of the site east of Proposed Lot 47. It is approximately 30 feet wide and 150 feet long and is sandwiched between two third-party properties. The third area is that panhandle at the southeast corner of the site as well as a triangular remnant created by the curvature of the proposed road. The City does not want ownership of this parcel and due to coal mine hazards south of it, it cannot be used for permanent access. In addition, as noted above,Tracts A and B are adjacent and associated with the Wetlands and Coal Mine areas respectively. The panhandle•could be traded or offered to the Sunnybrook development. CONCLUSIONS: 1. The proposed plat appears to satisfy the public use and interest. The proposed plat will provide a complement of small lot single family housing for those who do not want or need larger lots or homes. The disadvantage of this arrangement will be the large number of interior lots. Such lots may feel confined or hemmed in since they are surrounding by housing and possibly fences on all sides rather than an open streetscape. In addition,the easement access reduces the useful yard areas in some case but the lots do meet the various requirements of code. 2. The development of detached single-family uses on the R-10 parcel meets the policies and goals of the Comprehensive Plan. 3. The proposed plat provides for infill development in an area where urban services are available. The proposal also meets the required density,seven to ten units per acre,of the City. 4. The development should not tax either the road system or the existing utility infrastructure. The applicant will have to develop a road system in the plat and may have to develop roadways outside the plat if the Sunnybrook plat does not complete the necessary access roads. Cedar Avenue Preliminary Plat File No.:LUA-02-125,ECF,PP June 3,2003 Page 10 5. Development of the additional lots will increase the tax base of the City. The applicant has also been required to pay mitigation fees to offset its impacts on fire,parks and transportation systems. 6. Since a through road may be developed at the northwest corner of the plat where a stub road will be installed, staffs recommendation that a sign be posted is appropriate. 7. Since there may be unmapped coal mine areas outside of the known hazard areas,the applicant will be required to record restrictive covenants for the entire site that mirror those required by the ERC. 8. The common open space areas may create maintenance problems and the one adjacent to Proposed Lot 47 should be incorporated into that lot. The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook.

Any aggrieved person feeling that the decision of the Examiner is ambiguous or based on erroneous procedure, errors of law or fact,error in judgment,or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for a review by the Examiner within fourteen(14)days from the date of the Examiner's decision. This request shall set forth the specific ambiguities or errors discovered by such appellant, and the Examiner may, after review of the record,take further action as he deems proper. An appeal to the City Council is governed by Title IV,Chapter 8, Section 110,which requires that such appeal be filed with the City Clerk, accompanying a filing fee of$75.00 and meeting other specified requirements. Copies of this ordinance are available for inspection or purchase in the Finance Department,first floor of City Hall. An appeal must be filed in writing on or before 5:00 p.m.,June 17,2003. If the Examiner's Recommendation or Decision contains the requirement for Restrictive Covenants,the executed Covenants will be required prior to approval by City Council or final processing of the file. You may contact this office for information on formatting covenants. The Appearance of Fairness Doctrine provides that no ex parte(private one-on-one)communications may occur concerning pending land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents,of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. • • H4 • 29 T23N R5E E 1/2 A '" N 7 • l�'.1J ,b • c' y,� /f �S 'ant 111601 L—___ • cr. rza . / _ as 'any Ingot --T--.11:;—:, ........._\ ' ...A" :“.a c".§i0. �S 'any u�90t .. \ • Cr) _ o aS 'any 1190t .

The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Preliminary Plat Plan application,proof of posting, proof of publication and other documentation pertinent to this request. Exhibit No.3: Neighborhood Vicinity Map Exhibit No.4: Zoning Map Exhibit No. 5: Coal Mining Area Map Exhibit No. 6: Sensitive Areas Map Exhibit No. 7: Hazard Areas Map from Sunnybrook Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 2 The hearing opened with a presentation of the staff report by Leslie Nishihira, Senior Planner,Development Services, City of Renton, 1055 S Grady Way,Renton,Washington 98055. The proposal is to subdivide a 9.9- acre site into 50 lots intended for the development of detached single-family homes. The property is located in the southern portion on the City in the Talbot Hill area, abutting the division line between the City of Renton and King County. Surrounding the site are existing developments to the northeast under R-8 zoning, directly north are some undeveloped properties, zoned R-8, south are properties zoned R-10 and R-8, most recently the Sunnybrook plat was approved. There are coal mine hazardous areas that need to be avoided. The project was reviewed by the Environmental Review Committee(ERC)who issued a Determination of Non- Significance Mitigated(DNS-M). The DNS-M included twenty mitigation measures. There were no appeals filed. Measure one requires the project to comply with the recommendations contained within the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report,Measure two through five deal with temporary erosion control,measure six prohibits the placement of any structures,utilities, roadways within the designated high hazard areas,measure seven requires installation of a permanent fence surrounding the high hazard area, including signage at visible locations, measures eight and nine require informing future property owners of the coal mine hazard notice,measures ten and eleven require the applicant to comply with the 1998 King County Surface Water Drainage Manual with regard to flow control and the tight line drainage system, measure twelve requires the applicant to comply with the Wetland Study Report and Mitigation Plan,measure thirteen through fifteen requires the installation of silt fencing,permanent signage and fencing and a Native Growth Protection Easement to protect the wetlands,measures sixteen,nineteen and twenty were the standard fire,traffic and parks mitigation fees, and measures seventeen and eighteen requires a minimum 20' for all access roadways and that the applicant will provide the necessary means of access to serve the development. The proposal was routed to various City sections for review, comments have been incorporated into the Staff Report. The subject site is designated Residential Options on the Comprehensive Plan Land Use Map. The RO designation is designed to create new planned neighborhoods that include single family and multi-family developments. The proposal complies with infill development and RO policy LU-53 and LU-55. With respect to the underlying zoning designation,the density after deduction of the preserved wetland area, high coal mine hazard area,rights-of-way and private street easements the total 122,219 square feet of area,the resulting net acreage is 7.11 acres which results in a density of 7.03 dwelling units per acre which is just within the minimum range required. The proposal contains 100%of detached dwelling units,which is permitted in the R-10 zone. All lots comply with the minimum width, depth and area requirements. Two tracts are proposed in the project, Tract A, on the western portion of the site is 21,055 square feet and would contain the wetland and storm drainage areas. Tract B, in the north central portion of the property is approximately 33,825 square feet and would contain the High Mine Hazard Area. All lots,with the exception of 35 and 50,meets all front,rear and side yard setback requirements. Setbacks for these two lots do need to be corrected prior to recording the plat. Discussion ensued regarding portions of land adjoining lots 43,47 and 1 as to who would be responsible for their care and maintenance. They need to be included with the various lots or made a separate tract. The homeowners should be responsible, or the adjacent lots should have ownership of these parcels. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 3 There are existing structures on the property, including a single-family residence and detached accessory buildings. Staff recommends that these be demolished prior to recording of the plat. Side lot lines;are at right angles to street lines and are configured in a manner most suited to the existing topography of the site.All lots,with the exception of 3, 7, 8, 9, 10, 13, 14,34, 35, 36, 40, 41, 42,45, 46, 47, and 48 would have direct frontage to a newly created public roadway. The above exceptions would be serviced by private access drive easements proposed at 26 feet in width with 20 feet of paving. Staff has made additional recommendation requiring that the lots depicted on the plan meet all requirements for private roadways. Primary access to the site is proposed via an extension of a roadway that would be constructed as part of the Sunnybrook plat(proposed Road B)and would terminate at the northern property line. Extending eastward off Road B would be proposed Road A, bisecting the center portion of the site and connect to a secondary access point that is presently unimproved. This portion of Cedar Avenue is of substandard width and only includes 26 feet of roadway area with no paving. The project will be required to provide the appropriate paving width and turning radius for emergency access vehicles. The strip of land is not a dedicated right-of-way at this point. The public roads are proposed at reduced widths of 42 feet and would include 32 feet of paving along with curb, gutter, five-foot sidewalks and street lighting. The sidewalks are provided on both sides for Road A and B and are also included on the plan for the secondary access point on the northeast corner to the county roads. Staff recommends placement of permanent signage at the very northern end of Road B, indicating that at some point this road may be extended further north. Pedestrian linkage to the road that is part of the Sunnybrook project and further to Talbot road is required. The topographyIof the site slopes down from east to west with average slope of approximately 12% across the gpp Y property. Thie site is located in areas designated with potential coal mine hazards based on the City's Sensitive Area's Maps; It also contains slopes between 15-25%. Site is predominately vegetated with grasses and blackberries as well as cotton wood, maple, cedar,and pine trees,most of which would be removed during site preparation. Earthwork is estimated at 5,000 cubic yards of cut and fill. At completion, 60% of the site is estimated to be covered with impervious areas. The geotechnical report concludes that the site is suitable for the development provided that they comply with recommendations contained within that report. In addition, specific erosion control measures have been required by staff during the construction of plan improvements in individual building lots. It has been learned that the Springbrook II Mine underlies the site and dips at a very steep angle, approximately 61 degrees down to the south. There are also three back-filled mine openings in the north-central portion of the site. The report concludes that the Springbrook II Mine is substantially collapsed and there is no manifestation of regional ground substenance on the site. There is a high hazard area in the north-central portion of the property in Tract B. There are no low or medium hazard areas identified. SEPA required applicant to install split rail fencing around the High Hazard Area within Tract B. The subject site is surrounded by predominately single-family residences, in the north there is some undeveloped iproperty, and south there is the Sunnybrook proposal that will include all detached dwelling units. Within King County,just east of the project, are some apartments. Police,Fire,Recreation and the School District all indicated that provided that the applicant pay the required mitigation fees they could provide services to the proposed development. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 4 The applicant proposes to collect offsite flows near the eastern edge and reroute it to the site in a tight line drainage system underneath proposed Road A. This will exit the site approximately 22 feet from the southeastern property line into its existing drainage channel. No detention or water quality treatment is required. On site run off will be directed to a combination detention water quality pond and will discharge to the existing wetland in the southwest corner of the site. Staff requires that it comply with the 1998 Manual with SEPA conditions. Staff recommends as a condition of plat approval that the applicant be required to establish a Homeowners Association or Maintenance Agreement for common utility and roadway improvements included in the project. The wetlands map was made Exhibit 6, Sensitive Areas. There are four wetlands on the site. The wetland A was formed on top of fill legally placed on the property,the wetland hydrology is solely provided by the compaction of the soil and fill materials,and that the US Army Corp of Engineers will not take jurisdiction over the wetland. Wetland B and C are classified as category 3,both less than 5,000 square feet, and are permitted to be filled. Wetland D is a category 2 Emergent Wetland, as such it requires a minimum buffer within 50 feet. The City of Renton and The Soos Creek Water and Sewer districts serve the site. The applicant needs to contact Soos Creek Sanitary Sewer District for availability. In conclusion, staff recommends approval of the Cedar Avenue Preliminary Plat subject to conditions listed in the Staff Report. Lafe Hermansen, Core Design, 14711 NE 29th Place, Suite 101,Bellevue, WA 98007 stated that sewer and water availability have been applied for. Soos Creek has been contacted and they are awaiting an answer. Tract B,the intention of the division was to create a green space along the road,there is a view of the valley and mountains, also with the potential of a tot lot or something that would be secluded on that side of the street. The area around the High Coal Mine Hazard area is intended to be a grassy area with some trees. The area adjacent to Lot 47,the property owners have an option to purchase this land, so the strip in question could be added into a lot in the future. It will be included in Lot 47. The long skinny piece of property that runs north/south adjacent to Lot 1,we didn't know what the City was going to want to do with it, it was never a right-of-way to the County. It was thought to create an access trail through there to be maintained by the Homeowners Association. The Examiner asked if there was a coal mine hazard in that area. Ms.Nishihira responded that a hazard area is designated in the southern corner. Rob Stevens, Core Design, 14711 NE 29`h Place, Suite 101,Bellevue,WA 98007,civil engineer on the project and responsible for the storm drainage design. Regarding concerns of the wetlands being filled and how they were being compensated for in the detention facility. The wetlands were created by the coal mining activities, they are relatively created areas on sloped areas. The conditions used for the site are forested conditions,which are more conservative that actual wetlands. The detention facility has sized for the King County 1998 Manual Level 2 criteria. Neil Watts,Director Development Services, 1055 South Grady Way,Renton,WA 98055, stated that this site can be very confusing in terms of what we visualize wetlands being. Typically they are ponds and places where ducks reside, looking closely at the location of the larger wetland, it is on a fairly steep slope. Basically you have land that is wet versus the typical swamp or pond. Using forested pre-existing conditions is more conservative method of sizing for the new pond that being treated as a wetland. Regarding the piece of property running adjacent to Lot 1,there is no evidence that that strip was ever dedicated to the County or the City, it appears that it is still a piece of this parcel. The Administration's preference is that this remains as private property. Cedar Avenue Preliminary Plat " File No.: LUA-02-125,ECF,PP June 3,2003 Page 5 Oliver Grah,'Talasae Consultants,LLC, 15020 Bear Creek Road NE,Woodinville, WA 98072, commented that Wetland A, by the nature of its landscape position and the shape of the land form there, has very low storm water detention capacity,the loss of that wetland would not represent substantive increase in storm water runoff from the site: The Examiner called for further testimony regarding this project. There was no one else wishing to speak, and no further comments from staff The hearing closed at 10:05 a.m. FINDINGS,CONCLUSIONS &RECOMMENDATION Having reviewed the record in this matter,the Examiner now makes and enters the following: FINDINGS:' 1. The applicant,Dr.Baljinder and Rashpal Buttar,filed a request for approval of a 50-lot Preliminary Plat together with two tracts. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA) documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non'ISignificance-Mitigated(DNS-M)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is at 3521 Cedar Avenue South. The subject site is located southwest of SR-515 and north of Carr Road. Talbot Road South is located east of the subject site. 6. The subject site was annexed to the City with the adoption of Ordinance 4476 enacted in October 1994 (the staff report indicated the year was 1974). 7. The subject site is zoned both R-10(Residential Options permitting single family and attached housing). 8. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of residential options including detached single family and multiple family uses,but does not mandate such development without consideration of other policies of the Plan. 9. The subject site is approximately 9.9 acres or 432,069 square feet. The subject site is a generally rectangular parcel that is approximately 332 feet wide(north to south)by 1,318 feet long. A third-party property,not part of the proposal, is located near the northeast corner of the subject site and is surrounded by the subject site on the north,west and south. It has a long narrow panhandle at its southeast corner that is approximately 30 feet wide(east to west)by 280 feet long. The panhandle has beendescribed as an unopened right-of-way but title and record searches did not find any dedication or assignment to the public. (see below) 10. The site slopes downward from the east to the west approximately 140 feet or approximately 12%. The property drops in three stages or locations with the eastern third dropping approximately 8%to 15%,the central portion dropping approximately 18%to 27% and the western portion dropping approximately 8%. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 6 11. The site contains both wetland areas and high hazard coal mine areas. Three wetlands were determined to be unregulated and will be filled and developed. These are a small Wetland B (1,275 square feet)in the northwest corner of the site, a small Wetland C(740 square feet) in the southeast corner of the site and large Wetland A((12,211 square feet) in the center of the site. All are Category 3 wetlands. 12. Wetland D is a Category 2 wetland located in the western portion of the site. The wetland is approximately 59,138 square feet with approximately 28,572 square feet located on the subject site. This wetland would be preserved and requires a 50-foot wide buffer. The applicant's preparation of the site for development would disturb approximately 6,700 square feet of buffer area for this wetland. It would be restored after the needed work is complete. An exemption was granted to allow this work. In addition, an exemption will allow storm water to be discharged into the wetland and to allow storm water management facilities to be installed in the buffer but not the wetlands. 13. The coal mine area is located in the north central area of the site. The area is approximately 350 feet long(east to west)by 75 feet wide. This area will be left undeveloped and an area just north of it will also be left undeveloped since access to it would be difficult. Fencing will identify the area and signs will be installed to warn of potential danger in the area. 14. The subject site is covered by grasses,blackberries and some larger Cottonwood,Maple, Cedar and Pine trees. Most of the trees and smaller vegetation will be removed to allow the dense development permitted in the R-10 zone. The vegetation in the sensitive coal mine and wetland areas will be retained. 15. An existing home and outbuildings are located near the northeast corner of the subject site. 16. The applicant proposes dividing the property into 50 lots. In addition,the applicant proposes two larger tracts near the wetland in the west to contain storm water and north of the coal mine area in the center of the property, as well as some smaller landscaped or open space parcels in areas too small to contain building lots. One is east of the coal mine area, another is a narrow strip in the furthest northeast corner of the parcel and the third is the panhandle segment in the southeast corner of the plat. There would also be wetland and coal mine areas. 17. The applicant proposes developing the fifty lots with detached single-family homes although the R-10 would allow a mix of detached and attached dwelling units. 18. Most of the homes would be located north and south of a new road that would run west to east across the middle of the plat. This new road would be the primary access. It will connect on the west with a new north-south road that would extend from a roadway being developed by the recently approved Sunnybrook plat. At its eastern end the east-west road would swing north and connect to Cedar Avenue,which would serve as a secondary access. Cedar is a narrow substandard connection. 19. Lots would be aligned north and south of the primary access road in single, double and triple stacked lots. That is there would be a series of interior or internal lots that would not front directly on a road but would be accessed by an easement roadway. These interior lots will be constrained in size and surrounded on three or four sides by other homes. These interior lots would be very hemmed in by this development pattern. 20. There will be five easement roadways providing access to 18 interior lots,Lots 3, 7-10, 13, 14, 34-36, 40-43 and 45-48. In addition, staff recommended that the lots that have road frontage on both the public Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 7 roadway and these private easements use the easements for access in order to reduce the number of curb cuts on the public right-of-way. The lots affected by this recommendation would be lots 6, 11, 12, 33, 37, 44 and 49. 21. The westernmost,north-south road would be stubbed at the north property line of the subject site. This would eventually be extended to provide access to the property north of the subject site. Staff recommended that a sign be erected informing future residents that a through street is intended to be developed at that location. 22. The ERC required that the applicant provide both primary and secondary access roads to serve the development. This condition presupposes that if the adjacent Sunnybrook plat does not develop,that the applicant will still have to provide the necessary roads for access to the subject site. 23. The R-10 requires minimum lot sizes of 3,000 square feet for detached single-family homes. Lot width is 30 feet or 40 feet for corner lots and lot depth is 55 feet. The proposed lots vary from 3,600 square feet to 5,750 square feet. Lot width will vary from 35 feet to 55 feet and length will vary from 80 feet to 122 feet. 24. The applicant has specified the various yards for lots that front both public streets and the easement roadways. Proposed Lots 35 and 50 do not appropriately designate the appropriate front and rear yard setbacks. In addition, staff has noted that the lots are constrained by size and dimensions and that building pads for many of them should be oriented as noted in the following chart: Lot# Front Yard Rear Yard Side Yard Along Interior Side (10 feet) (15 feet) a Street(10 feet) Yard(s) (5 feet) 3 west property line east property line N/A north & south property lines 5 north property line south property line west property line east property line (exclusive of easmt) 6 east property line west property line north property line , south property line (exclusive of easmt) 7 east property line west property line N/A north& south (exclusive of property lines easmt) 8 east property line west property line N/A north & south property lines 9 west property line east property line N/A north & south property lines 10 west property line east property line N/A north &south (exclusive of property lines easmt) 11 west property line east property line north property line south property line (exclusive of easmt) 12 east property line west property line north property line south property line (exclusive of easmt) Cedar Avenue Preliminary Phil: File.No.: LUA-02-125,ECF,PP June 3, 2003 Page 8 13 east property line west property line N/A north&south (exclusive of property lines easmt) 14 east property line west property line N/A north& south property lines 33 east property line west property line south property line north property line (exclusive of easmt) 34 east property line west property line N/A north & south (exclusive of property lines easmt) 35 east property line west property line N/A north & south (must be property lines corrected) 36 west property line east property line N/A north&south (exclusive of property lines easmt) 37 west property line east property line south property line north property line (exclusive of easmt) 40 east property line west property line N/A north & south (exclusive of property lines easmt) 41 east property line west property line N/A north & south property lines 42 west property line east property line N/A north& south property lines 43 west property line east property line N/A north& south (exclusive of property lines easmt) 44 east property line west property line south property line north property line (exclusive of easmt) 45 east property line west property line N/A north&south (exclusive of property lines easmt) 46 east property line west property line N/A north& south property lines 47 west property line east property line N/A north&south property lines 48 west property line east property line N/A north& south (exclusive of property lines easmt) 49 west property line east property line south property line north property line (exclusive of easmt) 50 east property line west property line south property line north property line (must be corrected) Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP June 3,2003 Page 9 25. The development will increase traffic approximately 10 trips per unit or approximately 500 trips for the 50 single-family homes. Approximately 50 additional peak hour trips will be generated in the morning and evening. 26. The subject site is split between the Soos Creek Water and Sewer District and the City of Renton for water service. The two districts are working on the boundary. The site is entirely within the Soos Creek District for sanitary sewer. 27. The subject site is located within the Renton School District. The project is expected to generate approximately 22 school age children. These students would be spread across the grades and would be assigned on a space available basis. 28. The density for the plat would be 7.03 dwelling units per acre after subtracting sensitive areas(coal mine and wetland)and roadways. 29. There is R-8 zoning generally north,west and south of the site along Talbot Avenue South. R-10 is found south of the subject site. 30. As noted,the applicant proposes some common open space areas that would be under the control of a homeowners association. In one case the parcel is located south of Proposed Lots 40 and 43 in the center of the site. A private easement roadway would bisect the parcel. The second such parcel is located at the extreme northeast corner of the site east of Proposed Lot 47. It is approximately 30 feet wide and 150 feet long and is sandwiched between two third-party properties. The third area is that panhandle at the southeast corner of the site as well as a triangular remnant created by the curvature of the proposed road. The City does not want ownership of this parcel and due to coal mine hazards south of it, it cannot be used for permanent access. In addition, as noted above, Tracts A and B are adjacent and associated with the Wetlands and Coal Mine areas respectively. The panhandle could be traded or offered to the Sunnybrook development. CONCLUSIONS: 1. The proposed plat appears to satisfy the public use and interest. The proposed plat will provide a complement of small lot single family housing for those who do not want or need larger lots or homes. The disadvantage of this arrangement will be the large number of interior lots. Such lots may feel confined or hemmed in since they are surrounding by housing and possibly fences on all sides rather than an open streetscape. In addition,the easement access reduces the useful yard areas in some case but the lots do meet the various requirements of code. 2. The development of detached single-family uses on the R-10 parcel meets the policies and goals of the Comprehensive Plan. 3. The proposed plat provides for infill development in an area where urban services are available. The proposal also meets the required density, seven to ten units per acre, of the City. 4. The development should not tax either the road system or the existing utility infrastructure. The applicant will have to develop a road system in the plat and may have to develop roadways outside the plat if the Sunnybrook plat does not complete the necessary access roads. Cedar Avenue Preliminary Plat File No.: LUA-02-125,ECF,PP • June 3,2003 Page 10 5. Development of the additional lots will increase the tax base of the City. The applicant has also been required to pay mitigation fees to offset its impacts on fire,parks and transportation systems. 6. Since a through road may be developed at the northwest corner of the plat where a stub road will be installed, staffs recommendation that a sign be posted is appropriate. 7. Since there may be unmapped coal mine areas outside of the known hazard areas,the applicant will be required to record restrictive covenants for the entire site that mirror those required by the ERC. 8. The common open space areas may create maintenance problems and the one adjacent to Proposed Lot 47 should be incorporated into that lot. The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook. The portions adjacent to Proposed Lot 1 should be incorporated into that lot if the remainder is conveyed. 9. The development of the subject site will create additional traffic. There will also be additional noise associated with larger population. These impacts should not create any undue impacts on the overall community and were anticipated when the Zoning and Comprehensive Plan were adopted. 10. In conclusion,the proposed plat appears reasonable and should be approved by the City Council. RECOMMENDATION: The City Council should approve the Preliminary Plat subject to the following conditions: 1. A covenant that addresses the approved density of the site and the dwelling unit mix approved with the plat shall be created concurrently with the recording of the plat.A draft of the document shall be submitted to the City of Renton Development Services Division for review and approval by the City Attorney and Property Services section prior to the recording of the plat. 2. The applicant shall revise the plat plan in order to provide the correct yard setbacks for lots 35 and 50. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 3. The applicant shall obtain a demolition permit and complete all necessary inspections and approvals for the existing detached structures to be removed from the property. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 4. The applicant shall indicate on the face of the plat the location and orientation of the front,rear and side yard setbacks for each of the lots as depicted on the approved plat plan and as referenced in the table included in the staff report. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 5. The lots which front both the public roadway and a private street(lots 5, 6, 11, 12, 33,37, 44,and 49) shall utilize the abutting private street for driveway access and shall not be served directly off of the public roadway. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the issuance of the construction permits for the installation of roadway improvements for the development. Cedar Avenue Preliminary Plat File No.:LUA-02-125,ECF,PP June 3, 2003 Page 11 6. The applicant shall install permanent signage at the north end of public roadway"B"which indicates the roadway may be extended at a future date. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. 7. A homeowner's association or maintenance agreement shall be created concurrently with the recording of the plat in order to establish maintenance responsibilities for all shared improvements within this development. A draft of the document(s), if necessary, shall be submitted to the City of Renton Development Services Division for review and approval by the City Attorney and Property Services section prior to the recording of the short plat. 8. The applicant shall comply with the conditions imposed by the ERC. 9. The applicant shall provide a turnaround acceptable to the Fire Department. The turnaround can be abandoned or dismantled once adequate through or looped circulation is provided by development of adjacent properties. 10. Since through roads are anticipated from the new access road, signs should be posted that prominently note that the stubs or cul-de-sac will eventually create a roadway or roadways with through traffic. 11. The applicant shall be required to record restrictive covenants that mirror those required by the ERC for the entire site regarding coal mine hazards. 12. The common open space areas may create maintenance problems and the one adjacent to Proposed Lot 47 should be incorporated into that lot,unless conveyed to a third-party ownership. The open space panhandle and triangle adjacent to Proposed Lot 1 needs special treatment if portions of it are conveyed to Sunnybrook. The portions adjacent to Proposed Lot 1 should be incorporated into that lot if the remainder is conveyed. 13. The applicant shall obtain the necessary"will serve"written confirmation that both domestic water and sanitary sewer services are available to serve the plat. ORDERED THIS 3rd day of June, 2003.

Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. ki i` I.,. .N180,.---;,..r..'+a•.v�.. _ �. �...........,",„. . ,..., ;.sue. 3n5 ,,,iiiiit .7.<1.1„...„--es, will er..

PROJECT DESCRIPTION/BACKGROUND The applicant is requesting Preliminary Plat approval for the subdivision of a 9.9-acre site into 50 lots and two tracts. The lots, which have an average size of 4,431 square feet, are intended for the eventual development of detached single family residences. Tract A, at 21,055 square feet, is proposed as open space and would contain the portion of the site that is designated as a high coal mine hazard area. Tract B would accommodate the wetland area to be preserved, as well as the on-site storm drainage area, is proposed at 33,825 square feet in size. The property is presently developed with an existing residence and associated outbuildings — all of which would be demolished as part of site development. Primary access to the site would be provided via an extension of a public roadway from the southern property line that will be developed as part of the approved Sunnybrook Plat (file no. LUA-01-127). The roadway, which is proposed at a reduced right-of-way width of 42 feet, would extend northward and terminate at the northern property line. This road would also connect to an additional public roadway extending east through the center of the plat that would connect to the existing Cedar Avenue South right-of-way in order to provide secondary access to the property. The project would include the installation of code required street improvements and utilities for the development— most of which is dependent upon the completion of improvements installed in association with the Sunnybrook Plat. There are four wetlands on the site — three of which are exempt from the City's Wetland regulations and would be filled. The regulated wetland, located at the southwest corner of the site, would remain undisturbed. The site is also designated on the City's Sensitive Areas Maps as containing potential coalmine hazards and studies indicate high coalmine hazards are present in the north-central portion of the property. Site preparation activities would involve approximately 5,000 cubic yards of earthwork, with the removal of some trees anticipated for the creation of suitable building pads. The site is located within the Residential - 10 (R-10) dwelling units per acre (du/ac) zone and the Residential Options (RO) Comprehensive Plan Land Use Map designation. The R-10 zone typically allows residential densities that range from a minimum of 7.0 du/ac to a maximum of 10.0 du/ac, or 13.0 du/ac when all detached units are proposed. After the deduction of public and private roadways, as well as critical areas, from the gross acreage of the site, the proposal would arrive at a compliant net density of approximately 7.03 du/ac. In addition, the project would satisfy the dwelling unit mix provisions of the zone — which require a minimum of 50% to a maximum of 100% of the units to be detached. As all detached dwelling units are proposed, the project is not subject to Site Plan Review. hexrpt.doc • City of Renton P/B/PW Department liminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP PUBLIC HEARING DATE:MAY 20,2003 Page 4 of 14 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on April 22, 2003, the Environmental Review Committee issued a Determination of Non-Significance — Mitigated (DNS-M) for the Cedar Avenue Preliminary Plat. The DNS-M included 20 mitigation measures. A 14-day appeal period commenced on April 28, 2003 and ended on May 12, 2003. No appeals of the threshold determination were filed. 3. COMPLIANCE WITH ERC MITIGATION MEASURES Based on an analysis of the probable impacts from the proposal, the Environmental Review Committee issued the following mitigation measures with the Determination of Non-Significance— Mitigated (DNS-M): 1. The applicant shall comply with the recommendations contained within the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report, prepared by Icicle Creek Engineers, Inc. dated September 24, 2002 with regard to: site preparation, general earthwork, excavations, cut and fill slopes, fill settlements, and lateral resistance; use of structural fill and spread footings; design of floor slab support, sub grade walls, utilities, and pavements; and, methods of erosion control and permanent drainage measures. The satisfaction of these requirements shall be subject to the review and approval of the Development Services Division prior to the issuance of construction and building permits. 2. The applicant shall install a silt fence along the down slope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in Section D.4.3.1 of the King County Surface Water Design Manual, Appendix D. The satisfaction of this requirement shall be required during the construction of both off-site and on-site improvements as well as building construction. 3. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in Section 4.4.1 of the SWDM. Temporary pipe systems should also be used to convey storm water across the site. The satisfaction of this requirement shall be required during the construction of both off-site and on-site improvements as well as building construction. 4. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 5. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector for the preliminary plat construction. Certification of the installation, maintenance and proper removal of the erosion control facilities shall be required prior to recording of the plat. 6. The development shall not place any building structures, storm water detention facilities, roads or utilities within the designated high hazard areas, and shall be restricted from the use of mine rock fill containing more than 20% coal by weight as structural fill. The satisfaction of these requirements shall be subject to the review and approval of the Development Services Division throughout the duration of site preparation and building construction activities. 7. The applicant shall install permanent split-rail fencing with signage at visible locations around the perimeter of the "high"hazard area within Tract B in order to provide adequate notice to residents or visitors that there are known coal mine hazards in this area. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. hexrpt.doc • City of Renton P/B/PW Department liminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF,PP PUBLIC HEARING DATE:MAY 20, 2003 Page 5 of 14 8. The applicant shall place a note on the face of the plat, as well as record a restrictive covenant, subject to the review and approval of the City Attorney and the Property Services Section, prior to the recording of the plat which states the following: COAL MINE HAZARD NOTICE The lots created herein fall within a coal mine hazard area as identified by a Geotechnical Engineer at the time of this subdivision. Presence of such a hazard may trigger mitigation measures at the time of construction. No structures or improvements shall occur within high hazard areas. 9. The applicant shall record a restrictive covenant to run with the land that states the developer and all future home owners will hold the City harmless from any damages occurring from land movement, slide, collapse or other similar event caused by the coal mines known to exist beneath the site. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division and the City Attorney prior to the recording of the plat. 10. The applicant shall comply with the 1998 King County Surface Water Drainage Manual Level 2 Flow Control for the project. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the issuance of construction/utility permits. 11.

The applicant is required and intends to comply with each of these mitigation measures prior to the recording of the final plat. 4. STAFF REVIEW COMMENTS Representatives from various city departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. 5. CONSISTENCY WITH PRELIMINARY PLAT CRITERIA: Approval of a plat is based upon several factors. The following preliminary plat criteria have been established to assist decision makers in the review of the subdivision: (a) Compliance with the Comprehensive Plan Designation. The subject site is designated Residential Options (RO) on the Comprehensive Plan Land Use Map. The RO designation is intended to create new planned residential neighborhoods which include a variety of unit types designed to incorporate features from both single family and multi-family developments and to support infill development. The proposal is consistent with the RO designation in that it would provide for the future construction of single family homes and would promote goals of infill development. The proposed plat is consistent with the following RO policy: Policy LU-53. Detached single family housing, townhomes, and small scale multi-family units should be allowed in Residential Options. The proposal is to construct 50 detached single family dwellings—which is consistent with the RO designation. Policy LU-55. Development in Residential Options should be compatible with existing development patterns and be sensitive to unique features and differences among established neighborhoods. Development standards should reflect single family neighborhood characteristics such as ground related orientation, coordinated structural design, and private yards. The subject site is predominantly surrounded by established single family neighborhoods. The project would construct an additional 50 single family homes, which would be consistent with the character established by the existing surrounding neighborhoods. (b) Compliance with the Underlying Zoning Designation. The 9.9-acre site is designated Residential— 10 Dwelling Units per Acre (R-10) on the City of Renton Zoning Map. The proposed development would construct up to 50 new dwelling units. Density—The allowed density range in the R-10 zone is a minimum of 7.0 du/ac to a maximum of 10.0 du/ac, or 13.0 du/ac when all detached units are proposed. Net density is calculated after critical areas, public rights-of-way, and private streets serving more than three units are deducted from the gross acreage of the site. The property contains approximately 28,572 square feet of preserved wetland area, approximately 20,700 square feet of high coal mine hazard area, 59,865 square feet in area to be dedicated to public roadways, and approximately 13,082 in private street easement areas serving more than three units —or a total of 122,219 square feet of area, or 2.8- acres, to be deducted from the gross acreage of the site. Based on the resulting net acreage of 7.11-acres (309,850 square feet), the proposal for 50 units on the site would result in a net density of 7.03 du/ac and is in compliance with the density requirements of the zone. hexrpt.doc City of Renton P/B/PW Department liminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125, ECF, PP PUBLIC HEARING DATE:MAY 20,2003 Page 7 of 14 Building Standards/Platting Requirements —The R-10 zone permits only one residential structure per lot that may contain up to a maximum of 4 units. Based on this requirement, proposed developments in the R-10 zone require the approval of a subdivision. The R-10 zone also mandates that covenants be filed as part of the final plat in order to address the density and unit mix requirements of the zone. This requirement is recommended as a condition of preliminary plat approval. Dwelling Unit Mix — When proposing full subdivisions, the R-10 zone requires the provision of a minimum of 50% to a maximum of 100% of detached or semi-attached dwelling units. Therefore, for every attached unit proposed, at least one detached unit must be provided. The R-10 portion of the site would contain a total of 50 dwelling units, all of which are proposed to be detached units, thereby complying with the required dwelling unit mix. Lot Dimensions — The minimum lot area required in the R-10 zone for detached units is 3,000 square feet. A minimum lot width of 30 feet, or 40 feet for corners, is required per lot, along with a minimum lot depth of 55 feet. The 50 lots proposed within the R-10 designated portion of the site would include areas ranging from 3,600 square feet to 5,750 square feet in size. The proposed lot widths would range from 35 feet to 55 feet, with depths of 80 feet to 122 feet. In addition to the residential lots, tract A and tract B are proposed at 21,055 square feet and 33,825 square feet, respectively and would contain the critical areas portions of the property (i.e., wetland and high coal mine hazard), as well as the storm water drainage area for the project. As proposed, all lots appear to comply with the minimum lot size and dimensional requirements of the R-10 zone. Setbacks — The plat plan includes setback lines indicating potential building envelopes for each lot. For detached dwellings, the R-10 zone requires front and side yard along street setbacks of 10 feet for the primary structure and 20 feet for attached garages, rear yard setbacks of 15 feet, and interior side yard setbacks of 5 feet. When abutting a public roadway and a private street, lots are allowed the option to orient the front yard towards either roadway provided the appropriate rear yard setback is located opposite of this front yard. With the exception of lots 35 and 50, the proposal appears to comply with the required setbacks of the zone. As indicated on the plan, lot 35 does not provide the minimum required front yard setback opposite of the rear yard. In addition, lot 50 does not provide the minimum front yard setback along the street frontage opposite of the rear yard. The code required setback lines for each of these lots would need to be corrected prior to the recording of the plat. Although the existing structures on the property would be demolished as part of the proposal, in the event the structures were to remain subsequent to the recording of the plat they would be out of compliance with setback requirements. In addition, the R-8 zone permits accessory structures only when associated with a primary structure located on the same parcel. Once the property is platted, the existing detached structure would no longer be in compliance with the code. Therefore, in order to ensure the structures are appropriately demolished prior to the recording of the plat, staff recommends the applicant be required to finalize demolition permits as a condition of approval. (c) Compliance with Subdivision Regulations. Lot Arrangement: Side lot lines are to be at right angles to street lines, and each lot must have access to a public street or road. Access may be by private access easement per the requirements of the Street Improvement Ordinance. The side lines of the proposed lots are at right angles to street lines and are configured in a manner most suited to the existing topography of the property (i.e., terracing/rockeries between lots). All of the proposed lots, with the exception of lots 3, 7, 8, 9, 10, 13, 14, 34, 35, 36, 10, 41, 42, 43, 45, 46, 47, and 48, would have direct frontage to a newly created public roadway. These excepted lots would receive access via shared private street easements extending from either the north or south sides of the new public roadway. As proposed, all lots comply with arrangement and access requirements of the Subdivision Regulations. hexrpt.doc City of Renton P/B/PW Department _liminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF,PP PUBLIC HEARING DATE:MAY 20, 2003 Page 8 of 14 Lots: The size, shape and orientation of lots shall meet the minimum area and width requirements of the applicable zoning classification and shall be appropriate for the type of development and use contemplated. The majority of the lots satisfy the minimum lot area and dimensional requirements of the R-10 zone. The interior lots that are to be served by private streets, as well as the street fronting lots that abut these private streets, are depicted with front and rear yards oriented to the east and west. Although the shape and size of the proposed lots would preclude reasonable building pads if the setbacks were oriented differently, staff will recommend that future homes on these lots be required to have yard setbacks as depicted on the plan (upon the required corrections) in order to ensure driveway aprons and buildings are suitably constructed with an appropriate orientation within the development. Specifically, the required yard setbacks for those lots not abutting a public right-of-way and for those that are presently incorrectly labeled on the plan shall be as follows: Lot# Front Yard Rear Yard Side Yard Along a Interior Side (10 feet) (15 feet) Street(10 feet) Yard(s) (5 feet) 3 west property line east property line N/A north & south property lines 5 north property line south property line west property line east property line (exclusive of easmt) 6 east property line west property line north property line south property line (exclusive of easmt) 7 east property line west property line N/A north &south (exclusive of easmt) property lines 8 east property line west property line N/A north &south property lines 9 west property line east property line N/A north & south property lines 10 west property line east property line N/A north & south (exclusive of easmt) property lines 11 west property line east property line north property line south property line (exclusive of easmt) 12 east property line west property line north property line south property line (exclusive of easmt) 13 east property line west property line N/A north &south (exclusive of easmt) property lines 14 east property line west property line N/A north &south property lines 33 east property line west property line south property line north property line (exclusive of easmt) 34 east property line west property line N/A north &south (exclusive of easmt) property lines 35 east property line west property line N/A north &south (must be corrected) property lines 36 west property line east property line N/A north &south (exclusive of easmt) property lines 37 west property line east property line south property line north property line (exclusive of easmt) 40 east property line west property line N/A north &south (exclusive of easmt) property lines 41 east property line west property line N/A north &south property lines 42 west property line east property line N/A north &south property lines 43 west property line east property line N/A north & south (exclusive of easmt) property lines hexrpt.doc • City of Renton P/B/PW Department , ..iiminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125, ECF, PP PUBLIC HEARING DATE:MAY 20,2003 Page 9 of 14 44 east property line west property line south property line north property line (exclusive of easmt) 45 east property line west property line N/A north & south (exclusive of easmt) property lines 46 east property line west property line N/A north &south property lines 47 west property line east property line N/A north &south property lines 48 west property line east property line N/A north &south (exclusive of easmt) property lines 49 west property line east property line south property line north property line (exclusive of easmt) 50 east property line west property line south property line north property line (must be corrected) Furthermore, in order to reduce the number of curb cuts along the new public roadway and to ensure efficient movement of vehicles to and from the private streets, staff also recommends as a condition of plat approval that the lots which front both the public roadway and a private street (lots 6, 11, 12, 33, 37, 44, and 49) be required to utilize the private street for driveway access as opposed to being served directly off of the public roadway. When considering the required setbacks (upon correction), as well as access points for each lot, there appears to be sufficient building area for each lot to support the development of a suitable single family home. Property Corners at Intersections: All lot corners at intersections of dedicated public rights-of- way, except alleys, shall have minimum radius of 15 feet. The corner lots to be created by the proposed subdivision (lots 23, 32 and 50) would include the necessary radius required for public rights-of-way. (d) Reasonableness of Proposed Boundaries Access and Street Improvements: Primary access to the site would be provided via an extension of a public roadway from the southern property line, which will be developed as part of the approved Sunnybrook Plat (file no. LUA-01-127). This road (referred to as road "B") would extend northward for 200 feet and terminate at the northern property line, as well as connect to an additional proposed public roadway (road "A") that would extend approximately 900 feet east through the center of the plat. Road "A" would connect to the existing, but unimproved, Cedar Avenue South right-of-way that abuts the eastern property line; thereby, providing the necessary secondary access to the development. Cedar Avenue South, however, is presently of sub-standard width and includes only 26 feet of roadway area with no paving. As part of the proposal, the project would improve portions of Cedar Avenue in order to provide the necessary vehicular connection to SE 172nd Street. The roadway would be improved such that the appropriate turning radii for emergency access vehicles is provided. Further improvements to Cedar Avenue south of the connection point to road "A" is not included as that area contains high coal mine hazards (discovered upon review of the Sunnybrook Plat), which would preclude the extension of the road to Mill Avenue. In order to ensure emergency vehicles are able to efficiently access all areas of the residential development, all roadways of substandard width (i.e., private streets and the secondary access connection to SE 172nd Street) are required to be posted with "No Parking" signage and all addresses are required to be visible from the street as SEPA mitigation measures. The project includes five private streets to be created as private access and utility easements to serve lots not directly abutting proposed road "A". The private street easements are proposed at 26 feet in width and would include 20 feet of pavement (vehicular turnarounds would not be provided as they are less than 150 feet in length). Roads "A" and "B" are proposed at reduced widths of 42 feet and would include code required street improvements, such as 32-feet of paving, curb, gutter, 5-foot sidewalks and street lighting. In order to ensure future residents are aware of the potential for road "B" to become a connecting or through street to the north, the hexrpt.doc • City of Renton P/B/PW Department ,..'iminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP PUBLIC HEARING DATE:MAY 20, 2003 Page 10 of 14 applicant should be required to install permanent signage indicating the future potential of the roadway. The satisfaction of this requirement should be necessary prior to the recording of the plat. The project is required to provide a pedestrian linkage to a major arterial, for which the roadway to be extended from the Sunnybrook development would satisfy through its inclusion of sidewalks and an improved pedestrian connection to Talbot Road South. In the event the roadway from the south that is proposed to serve the project is not constructed as contemplated, the applicant has been required as a SEPA mitigation measure to provide the necessary means of access (both primary and secondary) in order to ensure residents, as well as emergency services, are able to reach the development. In addition, the proposal would result in an increase in traffic trips to the City's street system; therefore, a Traffic Mitigation Fee has been imposed by the Environmental Review Committee as part of the SEPA Determination issued for the project and will be required prior to the recording of the plat with credit given for the existing residence. Topography: The subject site generally slopes down from east to west with an average slope of approximately 12% across the property. The site is relatively even surfaced and includes slopes ranging from 8% to 15% grade in the eastern portion of the property, steeper areas of 18% to 27% grade in the central portion of the property, and flatter areas of nearly level to 8% grade in the western portion of the property. The property is located in an areas designated with potential coal mine hazards based on the City's Sensitive Areas Maps. The property also contains slopes between 15% to 25% according to the City's Steep Slopes Atlas. The site is predominately vegetated with grasses and blackberries, as well as Cottonwood, Maple, Cedar and Pine trees ranging in size from 6-inches to 30-inches in caliper—most of which would be removed during site preparation activities. Clearing limit boundaries are identified on the submitted plans and indicate avoidance of sensitive areas, including the high coal mine hazard in the north central portion of the property and the category 2 wetland located in the southwest corner. Earthwork activities are estimated at 5,000 cubic yards of cut and fill. At the completion of the project, approximately 60% of the site is estimated to be covered with impervious surface areas. The applicant has submitted a Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report, prepared by Icicle Creek Engineers, Inc. dated September 24, 2002 with the project application. According to the report, test borings suggest the entire property has surface disturbance from past grading activities, probably associated with previous coal mining activities and, to a lesser extent, agricultural purposes. This has resulted in one to four feet of fill and/or reworked topsoil generally consisting of loose to medium dense silty sand with variable amounts of gravel and occasional fragments of coal. The report states the loose fill and/or topsoil is generally underlain by native soils or bedrock, which should provide excellent support for buildings and roadways. Portions of the site do contain mine rock fill that is loose and contains organic materials, which should not be utilized as structural fill. In addition, the glacial till and bedrock that underlies the site limits vertical infiltration of water. With regard to geotechnical engineering, the evaluation concludes that the property can be satisfactorily developed as proposed with the use of conventional design and construction practices, provided the project complies with specified recommendations. These recommendations include measures regarding site preparation, general earthwork, excavations, cut and fill slopes, fill settlements, and lateral resistance; use of structural fill and spread footings; design of floor slab support, sub grade walls, utilities, and pavements; and, methods of erosion control and permanent drainage measures—all of which the applicant is required to comply with during site preparation and construction activities as a SEPA condition. In addition, due to possible erosion and sedimentation problems from construction activities on the site, specific erosion control measure must be implemented during both the construction of plat improvements and individual building lots. These measures include the use of silt fencing, shallow drainage swales, as well as daily review and maintenance of measures along with weekly reports on their status and condition — all of which are detailed in the listed SEPA mitigation measures. hexrpt.doc City of Renton P/B/PW Department . ..,liminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP PUBLIC HEARING DATE:MAY 20, 2003 Page 11 of 14 Coal Mine Hazards — According to the submitted assessment, a portion of the site is underlain by the Springbrook No. 2 Mine, which dips in a very steep angle of approximately 61 degrees down to the south. There are also three backfilled mine openings in the north-central portion of the site. On the abutting property to the north there are three abandoned mines (the J & J Mine, the King Mine and the Hi-Grade Mine). The report concludes that the Springbrook No. 2 Mine is substantially collapsed and that there is no manifestation of regional ground subsidence apparent on the site. The report's hazard assessment indicates that the north-central portion of the property (in the vicinity of the three mine openings), as well as the area containing the three off-site mines, would be classified as "high" coal mine hazard areas. No low or medium hazard areas were identified. In addition, mine rock fill areas occur across the central and northwest portion of the property. The report contains recommendations for mitigating potential impacts from coal mine areas, including the prohibition of building structures, storm water detention facilities, roads or utilities within the designated high hazard areas, as well as restricting the use of mine rock fill containing more than 20% coal by weight for use as structural fill —which the applicant is required to comply with as a SEPA mitigation measure. In order to provide adequate notice to residents and/or visitors that there are known coal mine hazards in this area, the applicant is required to install permanent split-rail fencing with signage at visible locations around the perimeter of the "high" hazard area within Tract B. In addition, the placement of a hazard notice on the face of the plat is required. Lastly, the recording of a restrictive covenant that states the developer and all future property owners would hold the City harmless from damages resulting from the known coal mine hazards will be necessary. All of these requirements have been imposed through the SEPA review process. Relationship to Existing Uses: The subject site is currently developed with an existing single family residence and detached accessory structures. The surrounding area includes single family residences developed under the R-8 and R-10 zoning designations. The proposed lots are compatible with other existing and newly created lots in this area. The proposal is consistent with the intent of the both the Comprehensive Plan and Zoning Code and would not be out of character with the existing or recent development in the area. (e) Availability and Impact on Public Services (Timeliness) Police and Fire: Police and Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development, subject to the condition that the applicant provide Code required improvements and fees. The Environmental Review Committee has imposed the payment of a Fire Mitigation Fee, with credit given for the existing residence, in order to mitigate the project's potential impacts to emergency services. Recreation: The proposal does not provide on-site recreation areas for future residents of the proposed plat. There are existing recreational facilities in the area of the subject property and it is anticipated that the proposed development would generate additional users of existing City park and recreational facilities and programs. As required by the Environmental Review Committee, payment of a Parks Mitigation Fee, with credit for the existing residence, will be required prior to the recording of the plat. Schools: The site is located within the boundaries of the Renton School District. Renton School District No. 403 has indicated that the increased student enrollment that may result from the development of the proposed project, estimated at 21.56 students (0.44 students x 49 new lots), can be accommodated by Talbot Hill Elementary School, Nelson Middle School and Hazen High School. The school district has indicated that these schools would be able to support the additional students generated by the proposal. Storm water: With the project application, a Drainage Report, prepared by Core Design dated September 2002, was submitted. According to the report, off-site flows enter the eastern edge of the property at two locations — at the north end of the site where it is captured by a ditch and conveyed to the southeast edge of the site at which point it joins the other entry point. Both flows enter a 40-foot long, 18-inch culvert which discharges into a ditch that runs along the south property line for approximately 250 feet and continues southwest onto the adjoining property. hexrpt.doc • • City of Renton P/B/PW Department . ..Jiminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP PUBLIC HEARING DATE:MAY 20,2003 Page 12 of 14 The off-site flow is eventually discharged into a wetland, which drains west into a 24-inch culvert that ultimately discharges to the Panther Creek wetland area. On-site, the drainage naturally sheet flows west across the property to the existing wetland located in the southwest corner of the property. This wetland discharges west into a ditch which becomes a moderately steep ravine for about 30 feet before transitioning to a 5-foot wide by 3- foot deep channel. Drainage water then flows under the north end of Morris Avenue in an 18- inch culvert before entering another similar channel continuing west and eventually reaching the Panther Creek wetland area. The project proposes to collect off-site flows near the eastern edge and reroute it through the site in a tight-lined drainage system underneath proposed roadway "A" that will exit the site approximately 220 feet from the southeastern property line into its existing drainage channel. As no additional flow from the development is proposed to be added to the off-site surface water flows, no detention or water quality treatment is proposed at this discharge point. On-site generated runoff will be directed to a combination detention/water quality pond, which will discharge to the existing wetland located in the southwest corner of the site. The conceptual drainage system has been designed in accordance with Level 2 Flow Control requirements. In order to ensure the developed project properly mitigates downstream drainage concerns and because it is not presently adopted by City of Renton code, the Environmental Review Committee (ERC) required the applicant to comply with the 1998 King County Surface Water Drainage Manual (KCSWDM) Level 2 Flow Control as a SEPA condition. In addition, as a SEPA mitigation measure the pipeline that will accommodate the rerouted off-site drainage flows is required to be sized appropriately to accept peak flows from the upstream drainage basin, in compliance with the 1998 KCSWDM. In order to ensure all common utility and roadway improvements are appropriately maintained, staff recommends as a condition of plat approval that the applicant be required to establish a homeowner's association or maintenance agreement for the development. Wetlands —The subject site contains four wetlands —wetland "A" in the central portion, wetland "B" in the northwest area, wetland "C" in the southeast corner, and wetland "D" in the southwest corner. With the project application, a Wetland Study Report and Mitigation Plan, prepared by Talasaea Consultants, LLC dated October 24, 2002, was submitted. According to the report, wetland "A" is a category 3 wetland of 12,211 square feet in size, which is hydrologically isolated from the other wetlands. Wetland "A" appears to have formed on top of a slightly convex mound of fill material that is higher in elevation than the surrounding uplands. Based on the Geotechnical Engineering Evaluation for the site, wetland "A"was formed on top of legally placed, compacted fill associated with past coal mine reclamation activities. This area consists of a 2-foot thick layer of mine rock fill and reworked topsoil that is underlain by a thin layer of compacted fill resulting in a shallow, perched groundwater table caused by the impermeable layer of the compacted fill. The wetland report concludes that mine rock fill was previously spread over upland soils in this area of the site, was further compacted by heavy machinery and allowed for perched groundwater to form a wetland. The City's wetland regulations establish that category 3 wetlands that are demonstrated to satisfy specified criteria — 1) the wetland formed on top of fill legally placed on a property; 2) the wetland hydrology is solely provided by the compaction of the soil and fill material; and, 3) the U.S. Army Corps of Engineers has determined that they will not take jurisdiction over the wetland — are considered non-regulated wetlands and are exempt from the City's code (RMC section 4-3-050.M.1.b). The applicant's wetland report, geotechnical study and criteria justification adequately demonstrate that wetland "A" is a non-regulated wetland. The report also indicates that wetland "B" and "C" are classified as category 3 wetlands, are less than 5,000 square feet in size (1,275 and 740 square feet, respectively) and are, therefore, not subject to the City's wetland regulations pursuant to section 4-3-050.B.7.a. However, wetland "D" is 59,138 square feet in size with approximately 28,572 square feet of the wetland located on the subject site and is subject to the U.S. Army Corps of Engineers jurisdiction. Based on City regulations, wetland "D" is considered a category 2, emergent wetland and requires a buffer width of 50 feet. hexrpt.doc City of Renton P/B/PW Department . ,_!iminary Report to the Hearing Examiner CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP PUBLIC HEARING DATE:MAY 20, 2003 Page 13 of 14 Although the proposal would not disturb wetland "D" and would provide the necessary 50-foot buffer, temporary impacts to the required buffer area are anticipated from development activities. The applicant has estimated that approximately 6,700 square feet of buffer area would be temporarily impacted and has further indicated that all impacted areas would be appropriately restored at a one-to-one ratio as required by code (RMC section 4-3-050.C.5.f.iii). In addition to the critical areas exemption for the temporary buffer impacts, the applicant requested exemptions to allow for storm water discharge to wetland "D" (allowed under section 4-3- 050.C.5.d.i) as well as to allow storm water management facilities to be located within wetland "D" buffer areas (allowed under 4-3-050.C.7.a.ii). The three requested exemptions were granted on April 16, 2003. In order to ensure impacts to the wetlands are appropriately mitigated and buffer areas are appropriately restored, the applicant is required to comply with the wetland mitigation plan contained with the submitted report, as well as employ specific identification and protection methods as SEPA conditions. Water and Sanitary Sewer Utilities: The proposed plat is within two water service areas, the City of Renton and Soos Creek Water and Sewer districts. The City of Renton and Soos Creek will be evaluating a service area boundary adjustment in order to arrive at a logical service boundary. The applicant will be informed as soon as an agreement on a preliminary boundary adjustment is' reached. The developer will be required to install and extend the City's and the District's water main for fire protection and domestic water service. The development is subject to both the City's and District's Water System Development fees and other applicable fees. The City of Renton Water System Development charges of $1,105 per new single family parcel will be required for this plat prior to issuance of the construction permit for the project. This project site is not served by the City of Renton sanitary sewer system. The applicant needs to contact the Soos Creek Sanitary Sewer District for availability, fees, plan review and permit information. Although the Soos Creek District will have the final review and approval the City will need to review the engineering design plans. G. RECOMMENDATION: Staff recommends approval of the Cedar Avenue Preliminary Plat, Project File No. LUA-02-125, ECF, PP subject to the following conditions: 1.

DESCRIPTION (continued from page 1) Primary access to the site would be provided via an extension of a public roadway from the southern property line that will be developed as part of the approved Sunnybrook Plat (file no. LUA-01-127). The roadway, which is proposed at a reduced right-of-way width of 42 feet, would extend northward and terminate at the northern property line. This road would also connect to an additional public roadway extending east through the center of the plat that would connect to the existing Cedar Avenue South right- of-way in order to provide secondary access to the property. The project would include the installation of code required street improvements and utilities for the development— most of which is dependent upon the completion of improvements installed in association with the Sunnybrook Plat. There are four wetlands on the site — three of which are exempt from the City's Wetland regulations and would be filled. The regulated wetland, located at the southwest corner of the site, would remain undisturbed. The site is also designated on the City's Sensitive Areas Maps as containing potential coalmine hazards and studies indicate high coalmine hazards are present in the north-central portion of the property. Site preparation activities would involve approximately 5,000 cubic yards of earthwork, with the removal of some trees anticipated for the creation of suitable building pads. The site is located within the Residential - 10 (R-10) dwelling units per acre (du/ac) zone and the Residential Options (RO) Comprehensive Plan Land Use Map designation. The R-10 zone typically allows residential densities that range from a minimum of 7.0 du/ac to a maximum of 10.0 du/ac, or 13.0 du/ac when all detached units are proposed. After the deduction of public roadways and critical areas from the gross acreage of the site, the proposal would arrive at a net density of approximately 6.61 du/ac. Although the project would fall below the minimum density required, the R-10 development standards allow density requirements to be reduced in the event the property contains physical constraints (i.e., sensitive areas) that preclude the ability to achieve the prescribed density. In addition, the project would comply with the dwelling unit mix provisions of the zone — which require a minimum of 50% to a maximum of 100% of the units to be detached. B.

ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. 1. Earth / Coal Mine Hazards Impacts: The subject site generally slopes down from east to west with an average slope of approximately 12% across the property. The site is relatively even surfaced and includes slopes ranging from 8% to 15% grade in the eastern portion of the property, steeper areas of 18% to 27% grade in the central portion of the property, and flatter areas of nearly level to 8% grade in the western portion of the property. The property is ercrpt.doc • City of Renton P/B/PW Department Enviror tal Review Committee Staff Report CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP REPORT OF APRIL 22,2003 Page 3 of 11 located in an areas designated by potential coal mine hazards based on the City's Sensitive Areas Maps. The property also contains slopes between 15% to 25% according to the City's Steep Slopes Atlas. The site is predominately vegetated with grasses and blackberries, as well as Cottonwood, Maple, Cedar and Pine trees ranging in size from 6-inches to 30-inches in caliper — most of which would be removed during site preparation activities. Clearing limit boundaries are identified on the submitted plans and indicate avoidance of sensitive areas, including the high coal mine hazard in the north central portion of the property and the category 2 wetland located in the southwest corner. Earthwork activities are estimated at 5,000 cubic yards of cut and fill. At the completion of the project, approximately 60% of the site is estimated to be covered with impervious surface areas. The applicant has submitted a Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report, prepared by Icicle Creek Engineers, Inc. dated September 24, 2002 with the project application. According to the report, test borings suggest the entire property has surface disturbance from past grading activities, probably associated with previous coal mining activities and, to a lesser extent, agricultural purposes. This has resulted in one to four feet of fill and/or reworked topsoil generally consisting of loose to medium dense silty sand with variable amounts of gravel and occasional fragments of coal. The report states the loose fill and/or topsoil is generally underlain by native soils or bedrock, which should provide excellent support for buildings and roadways. Portions of the site do contain mine rock fill that is loose and contains organic materials, which should not be utilized as structural fill. In addition, the glacial till and bedrock that underlies the site limits vertical infiltration of water. With regard to geotechnical engineering, the evaluation concludes that the property can be satisfactorily developed as proposed with the use of conventional design and construction practices, provided the project complies with specified recommendations. These recommendations include measures regarding site preparation, general earthwork, excavations, cut and fill slopes, fill settlements, and lateral resistance; use of structural fill and spread footings; design of floor slab support, sub grade walls, utilities, and pavements; and, methods of erosion control and permanent drainage measures — all of which staff recommends the applicant be required to comply with during site preparation and construction activities as a SEPA condition. In addition, due to possible erosion and sedimentation problems from construction activities on the site, staff recommends specific erosion control measure be implemented during both the construction of plat improvements and individual building lots. These measures include the use of silt fencing, shallow drainage swales, as well as daily review and maintenance of measures along with weekly reports on their status and condition —all of which are detailed below. Coal Mine Hazards — According to the submitted assessment, a portion of the site is underlain by the Springbrook No. 2 Mine, which dips in a very steep angle of approximately 61 degrees down to the south. There are also three backfilled mine openings in the north-central portion of the site. On the abutting property to the north there are three abandoned mines (the J & J Mine, the King Mine and the Hi-Grade Mine). The report concludes that the Springbrook No. 2 Mine is substantially collapsed and that there is no manifestation of regional ground subsidence apparent on the site. The report's hazard assessment indicates that the north-central portion of the property (in the vicinity of the three mine openings), as well as the area containing the three off-site mines, would be classified as "high" coal mine hazard areas. No low or medium hazard areas were identified. In addition, mine rock fill areas occur across the central and northwest portion of the property. The report contains recommendations for mitigating potential impacts from coal mine areas, including the prohibition of building structures, storm water detention facilities, roads or utilities within the designated high hazard areas, as well as restricting the use of mine rock fill containing more than 20% coal by weight for use as structural fill — which staff will recommend be required as a mitigation measure. In order to provide adequate notice to residents and/or visitors that there are known coal mine hazards in this area, staff recommends that the applicant be required to install permanent split-rail fencing with signage at visible locations around the perimeter of the "high" hazard area within Tract B. In addition, the applicant should be required to place a hazard notice on the face of the plat. Lastly, staff recommends the recording of airestrictive covenant that would state that the developer and all future property owners would hold the City harmless from damages resulting from the known coal mine hazards. ercrpt.doc • • City of Renton P/E/PW Department Environ fal Review Committee Staff Report CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF,PP REPORT OF APRIL 22,2003 Page 4 of 11 Mitigation Measures: • The applicant shall comply with the recommendations contained within the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation Report, prepared by Icicle Creek Engineers, Inc. dated September 24, 2002 with regard to: site preparation, general earthwork, excavations, cut and fill slopes, fill;settlements, and lateral resistance; use of structural fill and spread footings; design of floor slab support, sub grade walls, utilities, and pavements; and, methods of erosion control and permanent drainage measures.

Water'/Wetlands Impacts: With.!the project application, a Drainage Report, prepared by Core Design dated September 2002, was submitted. According to the report, off-site flows enter the eastern edge of the property at two locations — at the north end of the site where it is captured by a ditch and conveyed to the southeast edge of the site at which point it joins the other entry point. Both flows enter a 40-foot long, 18-inch culvert which discharges into a ditch that runs along the south property line for approximately 250 feet and continues southwest onto the adjoining property. The off-site flow is eventually discharged into a wetland, which drains west into a 24-inch culvert that ultimately discharges to the Panther Creek wetland area. On-site, the drainage naturally sheet flows west across the property to the existing wetland located in the southwest corner of the property. This wetland discharges west into a ditch which becomes a moderately steep ravine for about 30 feet before transitioning to a 5-foot wide by 3-foot deep channel. Drainage water then flows under the north end of Morris Avenue in an 18-inch culvert before entering another similar channel continuing west and eventually reaching the Panther Creek wetland area. The project proposes to collect off-site flows near the eastern edge and reroute it through the site in a tight- lined drainage system underneath proposed roadway "A" that will exit the site approximately 220 feet from the southeastern property line into its existing drainage channel. As no additional flow from the development is proposed to be added to the off-site surface water flows, no detention or water quality treatment is proposed at this discharge point. On-site generated runoff will be directed to a combination detention/water quality pond, which will discharge to the existing wetland located in the southwest corner of the site. The conceptual drainage system has been designed in accordance with Level 2 Flow Control requirements. In order to ensure the developed project properly mitigates downstream drainage concerns and because'it is not presently adopted by City of Renton code, staff recommends the applicant be required to comply with the 1998 King County Surface Water Drainage Manual (KCSWDM) Level 2 Flow Control as a SEPA condition. In addition, staff recommends as a mitigation measure requiring the pipeline that will accommodate the rerouted off-site drainage flows to be sized appropriately to accept peak flows from the upstream drainage basin, in compliance with the 1998 KCSWDM. Wetlands —The subject site contains four wetlands — wetland "A" in the central portion, wetland "B" in the northwest area, wetland "C" in the southeast corner, and wetland "D" in the southwest corner. With the project application, a Wetland Study Report and Mitigation Plan, prepared by Talasaea Consultants, LLC dated October 24, 2002, was submitted. According to ;the report, wetland "A" is a category 3 wetland of 12,211 square feet in size, which is hydrologically,isolated from the other wetlands. Wetland "A" appears to have formed on top of a slightly convex mound of fill material that is higher in elevation than the surrounding uplands. Based on the Geotechnical Engineering Evaluation for the site, wetland "A" was formed on top of legally placed, compacted fill associated with past coal mine reclamation activities. This area consists of a 2-foot thick layer of mine rock fill and reworked topsoil that is underlain by a thin layer of compacted fill resulting in a shallow, perched groundwater table caused by the impermeable layer of the compacted fill. The wetland report concludes that mine rock fill was previously spread over upland soils in this area of the site, was further compacted by heavy machinery and allowed for perched groundwater to form a wetland. The City's wetland regulations establish that category 3 wetlands that are demonstrated to satisfy specified criteria — 1) the wetland formed on top of fill legally placed on a property; 2) the wetland hydrology is solely provided by the compaction of the soil and fill material; and, 3) the U.S. Army Corps of Engineers has determined that they will not take jurisdiction over the wetland — are considered non-regulated wetlands and are ercrpt.doc • • City of Renton P/B/PW Department Enviror, tal Review Committee Staff Report CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF,PP REPORT OF APRIL 22, 2003 Page 6 of 11 exempt from the City's code (RMC section 4-3-050.M.1.b). The applicant's wetland report, geotechnical study and criteria justification adequately demonstrate that wetland "A" is a non-regulated wetland. The report also indicates that wetland "B" and "C" are classified as category 3 wetlands, are less than 5,000 square feet in size (1,275 and 740 square feet, respectively) and are, therefore, not subject to the City's wetland regulations pursuant to section 4-3-050.B.7.a. However, wetland "D" is 59,138 square feet in size with approximately 28,572 square feet of the wetland located on the subject site and is subject to the U.S. Army Corps of Engineers jurisdiction. Based on City regulations, wetland "D" is considered a category 2, emergent wetland and requires a buffer width of 50 feet. Although the ,proposal would not disturb wetland "D" and would provide the necessary 50-foot buffer, temporary impacts to the required buffer area are anticipated from development activities. The applicant has estimated that approximately 6,700 square feet of buffer area would be temporarily impacted and has further indicated that all impacted areas would be appropriately restored at a one-to-one ratio as required by code (RMC section 4-3-050.C.5.f.iii). In addition to the critical areas exemption for the temporary buffer impacts, the applicant has requested exemptions to allow for storm water discharge to wetland "D" (allowed under section 4-3-050.C.5.d.i) as well as to allow storm water management facilities to be located within wetland "D" buffer areas (allowed under 4-3-050.C.7.a.ii). The three requested exemptions were granted on April 16, 2003. In order to ensure impacts to the wetlands are appropriately mitigated and buffer areas are appropriately restored, staff',recommends the applicant be required to comply with the wetland mitigation plan contained with the submitted report, as well as employ identification and protection methods as specified below. Mitigation Measures: • The applicant shall comply with the 1998 King County Surface Water Drainage Manual (KCSWDM) Level 2 Flow Control for the project. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the issuance of construction/utility permits. • The tight-lined drainage system proposed to collect and reroute off-site drainage shall be sized to accept peak flows from the upstream drainage basin in compliance with the 1998 King County Surface Water Drainage Manual (KCSWDM). The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the issuance of construction/utility permits. • The applicant shall comply with the Wetland Study Report and Mitigation Plan prepared by Talasaea Consultants, LLC dated October 24, 2002 with regard to buffer restoration measures. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. • During site preparation and construction of improvements and residences, the applicant shall install silt fencing with brightly colored construction flags to indicate the boundaries of the wetland area and buffer. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division. • After the development of roadway and utility improvements, the applicant shall install permanent signage and fencing (i.e., wood split rail) in order to prevent intrusion and provide identification of the wetland area and buffers. The satisfaction of this requirement shall be subject to the review and approval of the Development Services Division prior to the recording of the plat. • The applicant shall establish a Native Growth Protection Easement for all preserved wetland areas and buffers.

Fire Prevention Impacts: Fire Prevention staff indicate that sufficient resources exist to furnish services to the proposed development project provided the applicant completes required improvements and makes payment of necessary fees. The proposal would include the construction of new residences that would potentially impact the City's Fire Department. Therefore, staff recommends requiring as a SEPA condition payment of a Fire Mitigation Fee based on a rate of $488.00 per new single family lot with credit given for the existing residence. The fee for this project is estimated at $23,912.00 (49 new single family lots x $488.00 = $23,912.00) and must be paid prior to the recording of the plat. Mitigation Measures: The applicant shall pay a Fire Mitigation Fee based on a rate of $488.00 per new single family lot with credit given for the existing residence.

Policy Nexus: SEPA Environmental Regulations; Fire Mitigation Fee Resolution No. 2913, Ordinance 4527. 4. Transportation Impacts: Primary access to the site would be provided via an extension of a public roadway from the southern property line, which will be developed as part of the approved Sunnybrook Plat (file no. LUA-01- 127). This road (referred to as road "B") would extend northward for 200 feet and terminate at the northern property line, ;as well as connect to an additional proposed public roadway (road "A") that would extend approximately,900 feet east through the center of the plat. Road"A" would connect to the existing, but unimproved, Cedar Avenue South right-of-way that abuts the eastern property line; thereby, providing the necessary secondary access to the development. Cedar Avenue South, however, is presently of sub-standard width and includes only 26 feet of roadway area with no paving. As part of the proposal, the project would improve the necessary portion of Cedar Avenue in order to provide the necessary connection to SE 172nd Street. The roadway would be improved in order to provide a minimum pavement width of 20 feet along with the appropriate turning radii for emergency access vehicles. A connecting sidewalk would also be installed along the east side of the road. Further improvements to Cedar Avenue south of the connection point to road "A" is not included as that area contains, high coal mine hazards (discovered when reviewing the Sunnybrook Plat), which would preclude the extension of the road to Mill Avenue. In order to ensure emergency vehicles are able to efficiently access all areas of the residential development, all roadways of substandard width (i.e., private streets and the secondary access connection to SE 172nd Street) must be posted with "No Parking" signage and all addresses must be visible from the street. The project includes five private streets to be created as private access and utility easements to serve lots not directly abutting proposed road "A". The private street easements are proposed at 26 feet in width and would include 20 feet of pavement (vehicular turnarounds would not be provided as they are less than 150 feet in length). Roads "A" and "B" are proposed at reduced widths of 42 feet and would include code required street improvements, such as 32-feet of paving, curb, gutter, 5-foot sidewalks and street lighting. In the event the roadway from the south that is proposed to serve the project is not constructed as contemplated, the applicant should be required as a SEPA mitigation measure to provide the necessary means of access (both primary and secondary) in order to ensure residents, as well as emergency services, are able to reach the development. In addition, the proposed development would result in an increase in traffic trips to the City's street system. Therefore, staff recommends requiring as a SEPA condition payment of a Traffic Mitigation Fee based on a rate of $75.00 per new average daily trip generated by the project with credit given for the existing residence. The fee for this project is estimated at $35,169.75 (49 new single family lots x 9.57 trips = 468.93 total trips x$75 = $35,169.75) and must be paid prior to the recording of the plat. Mitigation Measures: • The applicant shall provide a minimum pavement width of 20 feet for all access roadways, shall post all substandard roadways (i.e., those with less than 32 feet of pavement width) with "No Parking" signage, ercrpt.doc • City of Renton P/B/PW Department Enviror ;tal Review Committee Staff Report CEDAR AVENUE PRELIMINARY PLAT LUA-02-125,ECF, PP REPORT OF APRIL 22,2003 Page 8 of 11 and shall make all addresses be visible from the public street.

Policy Nexus: SEPA Environmental Regulations; Transportation Mitigation Fee Resolution No. 3100, Ordinance 4527. 5. Parks Impacts: The proposal does not provide on-site recreation areas for future residents of the proposed plat. However, there are existing recreational facilities in the area of the subject property (i.e., Thomas Teasdale Park, Philip Arnold Park). It is anticipated that the proposed development would generate residents that would utilize existing City recreational facilities and programs. Therefore, staff recommends requiring as a SEPA condition payment of a Parks Mitigation Fee based on a rate of $530.76 per new single family lot with credit given for the existing residence. The fee for this project is estimated at $26,007.24 (49 new single family lots x $530.76 = $26,007.24) and must be paid prior to the recording of the plat.

Because these notes are provided as information only, they are not subject to the appeal process for environmental determinations. Planning 1. It is likely that a forest practices permit from the Department of Natural Resources will be required prior to the development of the site. Please contact Dave Dietzman of DNR at (360) 825-1631 for more information. 2. RMC section 4-3-050.K.8 requires that any additional coal mine hazards discovered during construction must be reported to the Development Services Division immediately. Property Services 1. Comments regarding the final plat submittal will be forwarded under separate cover. Fire Prevention 1. One fire hydrant with 1,000 gpm fire flow is required within 300 feet of all new single family structures. If the building square footage exceeds 3,600 square feet in area, the minimum fire flow increases to 1,500 gpm and requires two hydrants within 300 feet of the structures. This distance is measured along a travel route. Plan Review—Water 1. The proposed plat is within two water service areas, the City of Renton and Soos Creek Water and Sewer districts. The two agencies will discuss and confirm the water service boundaries for the plat. The applicant will need to provide a certificate of water availability from the District for water service to the lots. 2. This project is required to install a new water main in order to serve the new lots with domestic water service and to satisfy fire flow requirements. 3. Additional fire hydrants must also be installed in order to satisfy fire protection requirements. All fire hydrants comply with City specifications. These City of Renton requirements are applicable to the entire site regardless of water district boundaries. 4. A Water System Development Charge of$1105.00 per new single family lot will be required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. Plan Review—;Sanitary Sewer 1. This project site is not served by the City of Renton sanitary sewer system. The applicant needs to contact the Soos Creek Sanitary Sewer District for service availability, fees, plan review and permit information. Plan Review Storm Drainage 1. A Surface Water System Development Charge of$525.00 per new single family lot will be required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. Building 1. Demolition permits will be required for the removal of the existing structures. 2. Building permits are required for any retaining walls in excess of 4 feet in height. ercrpt.doc - G4 - 20 T23N R5E W 1/2 • Stp _ - R � R-8 \'\r"\\ ' \\ !• RM-I y RM-I ,R:; R-8 S---25th-.St :::.

PROJECT NAME: Cedar Avenue Preliminary Plat OWNER/APPLICANT: Dr. Baljinder Buttar and Rashpal Buttar PROJECT MANAGER: Lesley Nishihira, x7270 PROJECT LOCATION: 3521 Cedar Avenue South PROPOSAL: The applicant is requesting Environmental (SEPA) Review and Preliminary Plat approval for the subdivision of a 9.92-acre site into 50 lots. The lots, which have an average size of 4,431 square feet, are intended for the eventual development of detached single family residences. There are three wetlands on the site - two of which are exempt from the City's Wetland regulations and would be filled. The regulated wetland, wetland "D," is located at the southwest corner of the site and would remain undisturbed. Wetland "D" is 59,138 square feet in total area with approximately 28,572 square feet of the wetland located on the subject site. Based on City regulations, wetland "ID" is considered a category 2, emergent wetland and requires a buffer width of 50 feet. It is also 'subject to the U.S. Army Corps of Engineers jurisdiction. Although the proposal would not disturb wetland "D" and would provide the necessary 50-foot buffer, temporary impacts to the required buffer area are anticipated from development activities. The applicant has estimated that approximately 6,700 square feet of buffer area would be temporarily impacted and has further indicated that all impacted areas would be appropriately restored at a one-to-one ratio as required by code (RMC section 4-3-050.C.5.f.iii). In addition to the critical areas exemption for the temporary buffer impacts, the applicant has requested exemptions to allow for storm water discharge to wetland "D" (allowed under section 4-3-050.C.5.d.i) as well as to allow storm water management facilities to be located within wetland "D" buffer areas (allowed under 4-3-050.C.7.a.ii). CRITICAL AREA: 28,572 square foot Category 2 Wetland (wetland "D" on attached plan) EXEMPTION JUSTIFICATION: Pursuant to the Specific Exemptions— Critical Areas and Buffers table of the City's Critical Areas Regulations, exemptions are hereby granted for the following;activities: X 4-3-050.C.5.f.iii.

The lots, which have an average size of 4,431 square feet, are intended for the eventual development of detached single family residences. There are three wetlands on the site - two of which are exempt from the City's Wetland regulations and would be filled. The regulated wetland, wetland "D," is located at the southwest corner of the site and would remain undisturbed. Wetland "D" is 59,138 square feet in total area with approximately 28,572 square feet of the wetland located on the subject site. Based on City regulations, wetland "D" is considered a category 2, emergent wetland and requires a buffer width of 50 feet. It is also subject to the U.S. Army Corps of Engineers jurisdiction.

New Surface Water Discharges: New surface water discharges to wetland Categories 1, 2 and 3, or buffers of Categories 1, 2 and 3, and to streams or lakes from detention facilities, presettlement ponds or other surface water management structures; provided, the discharge meets the requirements of the Storm and Surface Water Drainage Regulations (RMC 4-6-030); will not result in significant changes in the water temperature or chemical characteristics of the wetland or stream/lake water sources; and there is no increase in the existing rate of flow unless it can be demonstrated that the change in hydrologic regime would result in greater wetland or shoreline/stream/lake functions and values. Where differences exist between these regulations and RMC 4-6-030, these regulations will take precedence. X 4-3-050.C.7.a.ii. Stormwater Management Facilities in Buffer: Stormwater management facilities in critical area buffers including stormwater dispersion outfall systems designed to minimize impacts to the buffer and wetland where the site topography requires their location within the buffer to allow hydraulic function, provided the standard buffer zone area associated with the wetland classification is retained pursuant to RMC 4-3-050.M.6.c., and is sited to reduce impacts between wetland and surrounding activities. For Habitat Conservation Areas, this exemption applies only to Category 1 wetlands. DECISION: The proposed development is consistent with the following findings pursuant to RMC section 4-3-050.C.5: 1. The activity is not prohibited by this or any other chapter of the RMC or state or federal law or regulation; 2. The activity will be conducted using best management practices as specified by industry standards or.applicable Federal agencies or scientific principles; and, 3. Impacts are minimized and, where applicable, disturbed areas are immediately restored, unless the exemption is a wetland below the size thresholds pursuant to RMC 4-3- 050.C.5.f.1 and f.2. CONDITIONS OF APPROVAL: 1. The exemptions granted by this decision shall be applicable to the subject property only for the development of the site as approved under file no. LUA-02-125, ECF, PP.

Lafe Original Message From: Jeff Schramm [mailto:schramm@tenw.com] Sent: Friday, April 11, 2003 11:50 AM To: CORE- Lafe Hermansen Subject: RE: Cedar Ave Prel Plat afe, , I am aware of the signal that the City wants; I have been tracking it for the Sunnybrook project. The City currently does not have the signal identified on their six-year transportation improvement plan (TIP). Therefore, the plat should be reviewed with respect to the City's currently adopted plan. Buttar's Cedar Ave plat does not warrant the signal; in fact, we would have very little impact to that intersection. We only send 15 PM peak hour trips to it (11 trips in the AM peak hour),which is less than one percent(0.5%) of 'the total AM and PM peak hour traffic at that intersection. Rather than a proportionate share, I would suggest that the City apply our traffic mitigation fee to be used exclusively for the new signal at Carr Road/Mill Ave. Our mitigation fee is $37,500 which is $75 per daily f.'trip (500 trips), which is based on 50 residential lots. Let me know if you are looking for anything else. .

Thanks Jeff. -Lafe Original Message From: Lesley Nishihira [mailto:LNishihira@ci.renton.wa.us] Sent: Friday, April 11, 2003 11:01 AM To: CORE- Lafe Hermansen Subject: Cedar Ave Prel Plat Lafe, Our Transportation Department has indicated that this project will be required to contribute a fair-share of the cost of installing a traffic signal and approach widening in order to accomodate left-turns at the Mill Avenue/Carr Road intersection. This is because the primary access to the site is through the Sunnybrook Plat and the impacts from trips to and from both developments will trigger mitigation at this intersection. Before the City determines the percentage contribution required of this project, I'd'like to give you (or your transportation person)the opportunity to present what you, as the applicant, believes to be the appropriate share. That will give us a starting point for negotiations and, based on past experience, I have found is usually better than the City imposing a higher than expected amount at the beginning. We would need the proposed percentage of fair-share contribution along with justification for how the amount was determined. The project is scheduled to be presented to the Environmental Review Committee next Tuesday, so if you had something for me by then it would be very helpful. In either case,we expect them to table their decision until the following week when we have an agreed upon fair-share cost distribution. Tabling the issuance of the DNS-M a week will not have any bearing on the scheduled Hearing Examiner date. Let me know if you have any questions and when you think you can have this done by. Thanks!

FesserLR SUBJECT: Cedar Avenue Plat,LUA-02-125,PP Format and Legal Description Review Bob Mac Onie and I have reviewed the above referenced preliminary plat submittal and have the following comments: Comments for the Applicant: City records indicate that the east 30' of the north 332' (approx.) of the subject plat may be a county road. If that is the case,then the plat boundary needs to be changed accordingly to exclude said road. If that assumption is incorrect, provide deed documentation that states said 30' strip is part of the subject plat property. Also, identify what the easterly 30' strip of the plat is to be(between what is noted as"PUBLIC ROAD A"and the northerly margin of Mill Ave SE) —a road,tract or other. As currently shown, it is not part of proposed Lot 1 and has no label. Is the reservation of easement, recorded under King County Rec.No. 5335457, still an encumbrance on the subject property? It is not noted on the drawing. Information needed for final plat approval includes the following: Note the City of Renton land use action number and land record number,LUA-XX-XXX-FP and LND-10-0405, respectively, on the drawing,preferably in the upper right-hand corner. The type size used for the land record number should be smaller than that used for the land use action number. Please note that the land use action number for the final plat will be different from the preliminary plat and is unknown as of this date. Note two ties to the City of Renton Survey Control Network. The geometry will be checked when the ties have been provided. Provide plat and lot closure calculations. \H:\File Sys\LND-Land Subdivision&Surveying Records\LND-10-Plats\0405\RV030327.doc April 4, 2003 Page 2 Complete City of Renton Monument Cards,with reference points of all new right-of-way monuments set as part of the plat.

Note the date the existing monuments were visited,per WAC 332-130-150, and what was found. Note discrepancies between bearings and distances of record and those measured or calculated, if any. Note whether the adjoining properties are platted(give plat name and lot number)or unplatted. The city will provide addresses for the proposed lots after preliminary plat approval. The addresses need to be shown on the drawing. On the final plat submittal,remove all references to trees,topog lines and other items not directly impacting the subdivision. These items are provided only for preliminary plat approval. Encroachments do need to be shown. Required City of Renton signatures include the Administrator of Planning/Building/Public Works,the Mayor and the City Clerk. An approval block for the city's Finance Director is also required. The appropriate King County approvals need to be noted on the drawing also. All vested owners of the subject plat need to sign the final plat document. Include notary blocks as needed. Note that if there are restrictive covenants, easements or agreements to others as part of this subdivision,they can be recorded concurrently with the plat. The plat drawing and the associated document(s) are to be given to the Project Manager as a package. The plat shall have the first recording number. The recording number(s)for the associated document(s)will be referenced on the plat in the appropriate locations. If new private easements(such as the private access/utility easements shown on this plat) are shown for the benefit of future owners of the proposed lots,then include the following statement, juxtaposed to the subject easement areas: "Area for new private(water, sewer, utilities, access, etc.)easement." Since the new lots created via this plat are under common ownership at the time of recording,there can be no new private easement until such time as ownership of the lots is conveyed to others,together with and/or subject to specific easement rights.

The civil plans for Sunnybrooke are currently under review. This proposed plat (Cedar Ave) design is /A dependent on the Sunnybrook utilities being installed and accepted by the City of Renton. FFl NDs• Existing Conditions: Water--The proposed plat straddles the water service area boundary between the City of Renton and Soos Creek Water District. Therefore water service to the proposed plat will be provided by the ICity of Renton and also by Soos Creek Water& Sewer District.* This site is located in the City of �/— Renton 350 Pressure Zone. There is an existing 6" City of Renton watermain in Morris Av S. There is an existing 8" City of Renton watermain in S 36th St. There is an existing 6" City of Renton watermain in S 38th Ct. ISanitary Sewer--This project site is not served by the City of Renton sanitary sewer system. The applicant needs to contact the Soos Creek Sanitary Sewer District for availability, fees, plan review and permits. r Yi Storm--There are no storm drainage drawings in the City's records in the area of this development. This site is not located in the City of Renton Aquifer Protection Zone. / CODE REQUIREMENTS WATER Fp Now This project is required to install a new water main in order to serve the new lots with domestic water service to the individual lots and fire protection*. • The applicant will need a certificate of water availability from the District for water service to — the lots. • ' / , • Cedar Avenue Plat Page 2 • Fr l?fps • Any new construction must have a fire hydrant capable of delivering a minimum of 1,000 GPM fire and shall be located within 300 feet of the structure. If the proposed single-family structures exceed 3,600 square feet, the minimum fire flow increases to 1,500 GPM and requires two hydrants within 300 feet of the structure. This distance is measured along a travel route. Additional fire hydrants will be required as a part of this project to meet this criterion. All fire hydrants shall be per the City specifications. These City of Renton requirements are applicable to the entire proposed site regardless of water district boundaries. • The City of Renton Water System Development Charges of$1105 per new single family parcel will be required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. *The City will meet with the Soos Creek Water District to discuss and confirm the water service to this plat by the two agencies. SANITARY SEWER • Although the Soos Creek District will have the final review and approval the City still needs to see the sewer on the engineering design plans. STORM DRAINAGE • A drainage drainage w with the preliminary plat applicationconceptual for this project.plan Theand design drainage planreport as shallsubmitted include detention and water quality treatment for the fully built out plat, including future houses, driveways and roadway improvements. The runoff from the new houses must be tightlined into the storm drainage system constructed for the preliminary plat. The drainage plan is to be designed per the 1998 King County Surface Water Drainage Manual Level 2 Flow Control. The report that was submitted is under review at this time, but the preliminary review appears to be in order. The engineer does need to verify that the downstream system can handle the additional flows from this development. • Surface Water System Development Charges of $525 per new single family parcel will be _7 required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. EROSION CONTROL MEASURES C\) • Due to the possible erosion and sedimentation problems from construction activities on the site, / we will recommend the following conditions for this preliminary plat (for both preliminary plat development and future building permits for the individual lots): 1. The applicant shall install a silt fence along the downslope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is initiated, and shall be constructed in conformance with the specifications presented in Section D.4.3.1 of the King County Surface Water Design Manual, Appendix D. This will be required during the construction of both off-site and on-site improvements as well as building construction. 2. Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation growth shall be established in the ditch by seeding or placing sod. Depending on site n a Cedar Avenue Plat Page 3 grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in Section 4.4.1 of the SWDM. Temporary pipe systems can also be used to convey stormwater across the site. This will be required during the construction of both off-site and on-site improvements as well as building construction. 3. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 4. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector for the preliminary plat construction. Certification of the installation, maintenance and proper removal of the erosion control facilities shall be required prior to recording of the plat. P�'/1 Q STREET IMPROVEMENTS • The project needs to install street improvements including curb, gutter, sidewalk and street lighting and a minimum 20 foot pavement section all to City of Renton standards across the full p / frontage of the parcel being developed. , -• The new street interior to the plat must be developed to City standards, which are 42' right-of- way, full 32' pavement width, with curbs, gutters, 5' sidewalks adjacent to curb and street lighting. c_c C ._ _ ✓ •� Per City of Renton code streets that are longer than 700' are required to have two means of , -- access. The code does allow a dead end street if it is from 500' to 700' in length, has a full cul- c' de-sac and all houses beyond 500' have a sprinkler system. y • All new electrical, phone and cable services to the plat must be undergrounded. Construction of these franchise utilities must be inspected and approved by a City of Renton public works inspector prior to recording of the plat. 1.- G • Traffic mitigation fees of $35,169.75 are required prior to recording of the plat. This is a .1 condition-of-the-plat. GENERAL l2 • All required utility, drainage and street improvements will require separate plan submittals / prepared according to City of Renton drafting standards by a registered Civil Engineer. The construction permit application must include an itemized cost estimate for these improvements. The fee for review and inspection of these improvements is 5% of the first $100,000 of the estimated construction costs; 4% of anything over $100,00 but less than $200,000, and 3% of anything over$200,000. Half of this fee must be paid upon application for construction permits (preliminary plat improvements), and the remainder when the construction permit is issued. There may be additional fees for water service related expenses. ✓ - • All plans shall be tied to a minimum of two of the City of Renton Horizontal and Vertical Control Network. cc: Kayren K.

We have received the Notice of Application and Proposed Determination of DNS-Mitigated for the proposed action. Our initial calculations of'generated..trips based,on 50.Single-Family Detached Houses shows that there will be 39 AM peak hour trips and 51 PM peak-hour trips that will generated from this development (Trip Generation, 6th Edition, Institute of Transportation Engineers, 210). This fact along with the proximity of the development to SR-515 warrants WSDOT to request a review of the Traffic Impact Analysis (TIA)that was prepared for this development. A review of the TIA would help WSDOT identify the probability of impacts to SR-515. Our preliminary review shows that this development would have access to SR-515 via SE 172nd Street or Carr Road SE via Cedar Ave SE and 160th Place SE. If the main access for this development is through SE 172nd Street, then mitigations are probable due to how SE 172nd Street is situated with respect to SR-515 and safety issues that arises from the existing T-Intersection(No turning channelization from mainline, approach angle limits sight distance, approach grade also limits sight distance). On the other hand, access through Carr Road SE would present minimal impacts to SR-515 due to the Signal at the intersection with Carr Road SE. In addition, trip distribution could show minimal amount of trips impacting SR-515 via this access route due to multiple directions available at Carr Road SE. Again,we thank you for_this'-opportunity,to,comment through,SEPA on the,proposed,,; action mentioned above. WSDOT appreciates the commitment and effort by the City of Renton to involve WSDOT in all its SEPA actions and determinations.

The purpose of this memo is to provide the detailed justification based on the field investigation conducted by Talasaea Consultants, LLC as reported in the October 24, 2002 report and the geotechnical evaluation conducted of Wetland A by Icicle Creek Engineers, as reported in their September 24, 2002 report. Description of Wetland A Wetland A (12,211 sf), located in the central portion of the subject property, is an isolated, marginally wet area that formed on top of compressed fill material (Icicle Creek Engineers, 24 September 2002). Based on the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation (Icicle Creek, 2002), a 2-foot thick'layer of mine rock fill and reworked topsoil ,Is underlain by a thin layer of compacted fill that is causing shallow, perched groundwater conditions in Wetland A. The layer of fill placed over upland areas was likely compacted by heavy equipment working in this area when the surficial fill and topsoil was reworked. Wetland A formed on top of a slightly convex mound of fill material. These wet conditions occur in an area that is slightly higher in elevation than the surrounding uplands. This unusual condition is possible because of the perched water table caused by an impermeable layer of compacted fill. The mine rock fill material nearer the surface has higher permeability rates and lower pore pressure such that free water readily permeates to the compacted layer. This compacted layer does not allow for typical percolation rates of infiltrating surface water and thereby perches that water near the surface, JV1ine poil, with a.Smaller parti;clesize distribution and with greater degree of compaction creates a barrierqd'iriffitratiorilh 1IVet(and A l Further complicating groundwater patterns, in some Resource `cK Environmental Planning 15020 Bear Creek Road Northeast • Woodinville.

Wetland A is hydrologically isolated from other larger wetlands and wetlands adjacent to a :stream', The geotechnical evaluation revealed no locally high water table under the Compacted fill. There are no surface water connections to other wetlands, including surface flow or sheet flow, rills, gullies, or mineral channels, Pursuant to COE regulatory c:. policies and guidance, Wetland A, is considered isolated, The recent Supreme Court "SWANCC" decision prohibited isolated wetlands from being regulated as a Waters of the US under the Federal Clean Water Act. itkik icicle Creek Engineer's Geotechnicai Evaluation !title Creek Engineers (ICE's) conducted a geotechnical evaluation of the soils and subsoils of Wetland A (iCE's 2002), The following are paraphrases taken from this report: • Piles of coal existed in the central portion of the property that were later "leveled" by spreading this material out in the central to northwest portions of the property. • The entire property has surface disturbance from past grading activities, probably associated with previous coal mining activities and, to a lesser extent, agricultural purposes• • The surface disturbance has resulted in one to four feet of fill and/or reworked topsoil mantling the property with an average thickness of about two feet. Locally, the fill is thicker, from six to ten feet thick. • Test Pits TP-16 and TP-17 were excavated in Wetland A. Based on these test pits, there is a two-foot thick layer of fill and reworked topsoil underlain by a thin layer of compacted soil that is causing the shallow, perched ground water conditions. The thin layer of compacted soil was likely caused by heavy equipment working in this area when the surficial fill and topsoil was reworked, • No groundwater was encountered in test pits TP-12 through TP-26. Thus, no groundwater was encountered in TP-,16 and TP-17. • Based on our knowledge of site history, site observations and test pit explorations, it appears that the wetland conditions of Wetland A have been created by past site grading activities. • These grading activities appear to have compacted a thin layer of fill with heavy equipment traffic near the contact with underlying native soils. • The material overlaying the tin compacted layer consists of loose fill and reworked topsoil. • In our opinion, this condition of the thin layer of compacted soil overlain by less dense and more permeable soil causes shallow groundwater to concentrate in this area during the wet season. As can be readily discerned from icicle. Creek .Engineer's geotechnical analysis as paraphrased above, Wetland:A has.developed on top of compacted fill from the re-grading activities associated:witih reclamation of. the coal mine as well as to prepà The site for Pc' Mr. Lafe Hermansen 6 March 2003 Page 3 agricultural use, The compacted fill was placed over the native upland soils. Due to an impeding layer within the compacted fill, a seasonally perched shallow water table exists; however, this water table is isolated from groundwater in the underlying upland soils. City Code Renton City Code, Section RDR 4-3-050M(1)(b), specifically addresses the occurrence of Class 3 wetlands that form on top of legally placed fill as follows: M. WETLANDS: 1. Applicability: In addition to general standards of subsection E of this Section, the following performance stendvds apply to all regulated wetlands. a. Regulated and Nonregulated Wetlands - General: Wetlands created or restored as a part of a mitigation project are regulated wetlands. Regulated wetlands do not include those artificial wetlands intentionally created from nonwetland sites for purposes other than wetland mitigation, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm pond, and landscape amenities, or those wetlands created after July 1, 1990 that were unintentionally created as a result of the construction of a road, street, or highway. The Department Administrator shall determine that a wetland Is not regulated on the basis of photographs, statements, and other evidence. b. Nonregulated Category 3 Wetlands: Based upon an applicant request, the Department Administrator may determine that Category 3 wetlands are not considered regulated wetlands, if the applicant demonstrates the following criteria are met: i. The wetland formed on top of fill legally placed on a property; and ii. The wetland hydrology is solely provided by the compaction of the soil and fill material: and iii. The U.S. Army Carps of'Fnginters has determined that they will not take jurisdiction over the wetland. Evaluation of Non-regulated Category 3 Wetlands Under Renton City Code Renton.City Code, RDR 4-3-060M(1)(b), specifically addresses isolated wetlands that formed on lop of legally placed fill. Wetland A is not a regulated feature under Renton's Code (RDR 4-3-050M(1)(b)) because this Category 3 wetland: 1) formed on top of legally placed fill material, 2) appears to have been created through the compaction of mine rock fill material, and 3) is an isolated wetland not regulated by the Corps.

The Fire Department has informally reviewed the roadway plan dated December 11, 2002 and has determined that the secondary access to the plat is acceptable as proposed. Comments have been made, however, that the proposed vertically stacked lots (i.e., lots 6 through 14, 33 through 37, 41 through 49) do not comply with the City's Subdivision Regulations. Specifically,these lots should be re-designed such that the orientation of the homes to be built on them are consistent with those that will contain homes facing the street. Please consider this when preparing the revised application materials described below. In order to accept and process your submittal,the following items will be required: 1. Wetlands — According to the submitted Wetland Study Report and Mitigation Plan prepared by Talasaea Consultants dated October 24, 2002, wetland A is a 12, 211 square foot category 3 wetland. The wetland report states that this wetland is not subject to the City's Wetland Regulations under the applicability section of the code (RMC 4-3-050.M.1.b). In order to review the wetland under this determination, detailed justification as to how the wetland satisfies the criteria specified under RMC 4-3-050.M.1.bmust be provided. It is likely that the Administrator will require the independent review of this request by the City's on-call wetland biologist consultant. 2. Revised Plans— Please submit the appropriate number of copies of the Preliminary Plat Plan (12), Grading and Utility Plan (5), and Road Profiles (5, if necessary) that have been revised to be consistent with the modified roadway plan and the suggested lot reconfiguration. In addition, revised PMT reductions and color display maps of the new plans will be necessary. At this time your land use application has not been accepted as complete. The items listed above will need to be addressed in order to accept and initiate the review of your proposal.

Q:\WEB\PW\DEVSERVWFORM\aformdensity.doc06/27/02 1 r d Project Narrative / -% Cedar Avenue Property-- Renton,Washingtonot - ®C�'j. 9 • Project Name: Cedar Avenue Property 6C" ~c, , V2c Project Size: The total site is approximately 9.92 acres. ��� Location of Site: The project is located to the north of the proposed preliminary plat of Sunnybrook. The site is approximately one block west of the intersection of State Highway 515 and SE 172 Street. • Current zoning: Residential 10 du/ac Surrounding zoning: North: Residential 8 du/ac (Plat of Winsper) South: Residential 8/10 du/ac (Prop. Plat of Sunnybrook) West: Residential 8 du/ac (Single-family homes) East: Unincorporated King County (Summerhill Apt.'s) • Current use: The site is currently developed with one single-family residence and two associated outbuildings (one barn and one stable, both dilapidated). All existing structures on site will be removed. Demolition permits and inspections will be obtained prior to the removal of the structures. Special site features: There are three wetlands located on the property. Two of the wetlands will be filled as part of this project. The largest wetland,located in the southwest corner of the site will remain undisturbed. Please see the wetland report prepared by Talasaea Consultants for more specific information. There is a high coal mine hazard area located in the center of the property. Please see the Coal Mine Hazard Assessment prepared by Icicle Creek Engineers. There are no steep, sensitive, or protected slopes located on the site. • Soil type and Drainage: According to the report by Icicle Creek Engineers the site is entirely underlain by weathered glacial till consisting of medium dense silty sand with gravel and variable amounts of cobbles. For more specific information on the soil type please refer to the Preliminary Geotechnical Engineering Study prepared by Icicle Creek Engineers. A preliminary storm drainage system has been designed to handle all the stormwater run-off that will be generated by the site. The system will include temporary erosion control barriers during site construction, and a permanent storm pond,located in the northwest corner of the property. This permanent system will ensure that prior to the discharge of stormwater into wetland D, the on-site system will have 02027 Proj Narrative, 10/30/02 a ' a • significantly reduced the potential impacts to ground and surface waters. • Proposed property use: The proposal is to subdivide the property into 50 lots. The project will create one new public road and extend the road stubbed to the south property line by the proposed preliminary plat of Sunnybrook. The project will also create 5 access easements that will access from the new public road. Per City of Renton Development Regulations Section 4-6-060 R.3,Reduced Right-of-Way Dedication,we are proposing to reduce the right-of-way width for public Road A and B from 50 feet to 42 feet. This reduction allows the creation of additional lots within the shape and size constraints of the site and matches the right-of-way that was extenden to the site by the property to the south. • Access: The project is proposing to gain access from NE 172nd Street via a new 42'wide public street. The other access will be from extending the public road that was extended to the south property line from the proposed preliminary plat of Sunnybrook. • Off-site improvements: There are no off site improvements proposed as part of this project. • Est. Construction Costs: $200,000 • Est. fair market value: $950,000 • Quantity and type of fill: At this point in the design process, the site is anticipated to be balanced by cutting and filling. The quantities of the cut and fill that will occur on site are approximately 5000 cubic yards. If it is discovered that the site will need fill material, the applicant will submit a fill source statement at that time. • Trees to be removed: Every effort will be made to retain as many trees as possible. Please see the Tree Cutting/Land Clearing plan for the approximate location of the clearing limit. • Land dedication: Not applicable. • Number, size, and density of lots: There are 50 lots proposed for the property. The average lot size is approximately 4,431 S.F. The net density is approximately 6.61 du/ac. 02027 Proj Narrative, 10/30/02 b • Proposed job shacks: The site will have a construction trailer during the construction of the development. • Density: According to the Renton Development Regulations the minimum density for the R-10 zone is 7 du/ac. for parcels over '/z gross acre. The Cedar Avenue property is currently at 6.61 du/ac. A modification to the Renton Development Regulations is hereby requested. The project is constrained with slopes,wetlands, and high coal mine hazard areas. In addition, the proposed lot size is essentially 45 feet wide by 80 feet deep,which will allow the creation of an attractive streetscape by reducing the visual impact of the garages. The property owners do not want to propose attached homes or smaller lots due to the surrounding single-family homes or lots that abut the property on•three sides as well as the rolling topography of the site. 02027 Proj Narrative, 10/30/02 1 + AFFIDAVIT OF INSTALLATION OF PUBLIC INFORMATION SIGN City of Renton Development Services Division 1055 South Grady Way, Renton, WA 98055 Phone:425-430-7200 Fax: 425-430-7231 STATE OF WASHINGTON ) OFf c, rpoF gR,00 COUNTY OF KING ) Oct ry yr N;vivo • ikri,„, 4 2-01 , bei duly sworn on oath, deposes and says: 1.

THE APPLICANT IS CAUTIONED THAT INFORMATION CONTAINED IN THIS SUMMARY MAY BE SUBJECT TO MODIFICATION AND/OR CONCURRENCE BY-OFFICIAL DECISION MAKERS (E.G. HEARING EXAMINER,' BOARDS OF ADJUSTMENT, BOARD OF PUBLIC WORKS AND,CITY COUNCIL). REVIEW COMMENTS MAY ALSO NEED TO BE REVISED BASED ON SITE PLANNING AND OTHER DESIGN CHANGES REQUIRED BY THE CITY OR MADE BY THE APPLICANT. • •I have reviewed the preapplication submittal for this 50 lot plat located in Section 29, Twp. 23N Rng. 5E, and have the following comments. WATER • The proposed plat straddles the water service area boundary between the City of Renton and Soos Creek Water District.. • Therefore water service to the proposed plat will be provided by the City of Renton and also by Soos Creek Water& Sewer District. * I • The applicant will need a certificate of water availability from the District for water service to the attached units. • Renton will issue a certificate of water availability for the single family lots. • This site is not located in the City of Renton Aquifer Protection Zone. • This site is located in the City of Renton 350 and in the 490 Pressure Zone. • There is an existing 8" City of Renton watermain in S 36th St. Cedar Ave Plat Reapplication • ° July 25,2002 Page 2 • There is an existing 6" City of Renton watermain in S 38th Ct. • Any new construction must have a fire hydrant capable of delivering a minimum of 1,000 GPM fire and shall be located within 300 feet of the structure. If the proposed single-family structures exceed 3,600 square feet, the minimum fire flow increases to 1,500 GPM. and requires two hydrants within 300 feet of the structure. This distance is measured along a travel route. Additional fire hydrants will be required as a part of this project to meet this criteria. All •fire hydrants shall be per the City specifications. These City of Renton requirements are applicable to the entire proposed site irregardless of water district boundaries. • The City of Renton Water System Development Charges of $1105 per new single family parcel will be required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. *The City will meet with the Soos Creek Water District to discuss and confirm the water service to this plat by the two agencies. SANITARY SEWER • This project site is not served by the City of Renton sanitary sewer system. • The applicant needs to contact the Soos Creek Sanitary Sewer District for availability, fees, plan review and permits. • • Although the Soos Creek District will have the final review and approval the City still needs to ' see the sewer on the engineering design plans. STORM DRAINAGE • There do not appear to be any storm drainage drawings in the City's records in the area. • A conceptual drainage plan and drainage report shall be submitted with the preliminary plat application for this project. The conceptual drainage plan is to include detention and water quality treatment for the fully built out plat, including future houses, driveways and roadway improvements. The runoff from the new houses must be tightlined into the storm drainage system constructed for the preliminary plat. The drainage plan is to be designed per the 1998 King County Surface Water Drainage Manual Level 2 Flow Control. • Surface Water System Development Charges of $525 per new single.family parcel will be required for this plat. This fee must be paid prior to issuance of the construction permit for the preliminary plat. EROSION CONTROL MEASURES • Due to the possible erosion and sedimentation problems from construction activities on the -- site, we will recommend the following conditions for this preliminary plat (for both preliminary plat development and future building permits for the individual lots): • 1. The applicant shall install a silt fence along the downslope perimeter of the area that is to be disturbed. The silt fence shall be in place before clearing and grading is , ' Cedar Ave Plat Reapplication July 25,2002 Page 3 initiated, and shall be constructed in conformance with the specifications presented in Section D.4.3.1 of the King County Surface Water Design Manual, Appendix D. This will be required during the construction of both off-site and on-site improvements as well as building construction. 2. r Shallow drainage swales shall be constructed to intercept surface water flow and route the flow away from the construction area to a stabilized discharge point. Vegetation j growth shall be established in the ditch by seeding or placing sod. Depending on site grades, it may be necessary to line the ditch with rock to protect the ditch from erosion and to reduce flow rates. The design and construction of drainage swales shall conform to the specifications presented in Section 4.4.1 of the SWDM. Temporary pipe systems,can also be used to convey stormwater across the site. This will be required during the construction of both off-site and on-site improvements as well as 'building construction. 3. The project contractor shall perform daily review and maintenance of all erosion and sedimentation control measures at the site during the construction of both off-site and on-site improvements as well as building construction. 4. Weekly reports on the status and condition of the erosion control plan with any recommendations of change or revision to maintenance schedules or installation shall be submitted by the project Engineer of record to the public works inspector for the preliminary plat construction. Certification of the installation, maintenance and proper removal of the erosion control facilities shall be required prior to recording of the plat. STREET IMPROVEMENTS • The project needs to install street improvements including curb, gutter, sidewalk and street lightin all to City of Renton standards across the full frontage of the parcel being developed. • A traffic study will be required. • The new street interior to the plat must be developed to City standards which are 42' right-of- way, full 32' pavement width, with curbs, gutters, 5' sidewalks adjacent to curb and street lighting,. - • Two streets need to be extended. One street needs to be extended to the south to align with the roadway proposed in Sunnybrook. One street, the most westerly street as shown in this current site proposal needs to be extended to the north property line. • Per City of Renton code streets that are longer than 700' are required to have two means of access.' The code does allow a dead end street if it is from 500' to 700' in length, has a full cul-de-sac and all houses beyond 500' have a sprinkler system. • All new electrical, phone and cable services to the plat must be undergrounded. Construction of these franchise utilities must be inspected and approved by a City of Renton public works - inspector prior to recording of the plat. • Traffic mitigation fees of approximately $75 per net new average daily trip will be required prior to', recording of the plat. Fire mitigation and Parks mitigation fees must also be paid prior toj recording of the plat. Cedar Ave Plat Reapplication July 25,2002 Page 4 GENERAL • All required utility, drainage and street improvements will require separate plan submittals prepared according to City of Renton drafting standards by a registered Civil Engineer.

CITY OF RENTON Planning/Building/Public Works MEMORANDUM DATE: July 25, 2002 TO: Pre-Application File No. 02-054 FROM: Lesley Nishihira, Senior Planner,x7270 .v SUBJECT: Cedar Avenue(Buttar) Preliminary Plat General: I We have completed a preliminary review of the pre-application for the above- referenced development proposal. The following comments on development and permitting issues are based on the pre-application'submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained'in this summary may be subject to modification and/or concurrence by official decision- makers (e.g., Hearing Examiner, Zoning Administrator, Board of Adjustment, Board of Public Works, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available for purchase for $55, plus tax, from the'Finance Division on the first floor of City Hall. Project Proposal: The subject site is situated west of Cedar Avenue and north of Carr Road. The property is presently developed with a residence and accessory structures, which would be removed as part of site development. The proposal is to subdivide the approximately 9.92-acre (432,069 square feet) size property into 50 lots intended for the development of detached single family homes. The installation of public roadways, as well as utilities necessary to serve the development are also included with'the project. Zoning/Density Requirements: The subject property is located within the Residential - 10 dwelling units per acre (R-10) zoning designation. The density range allowed in the R-10 zone is a minimum of 7 to a maximum of 10 dwelling units per acre (du/ac). For lots under one-half acre in size,the minimum density requirements do not apply. The maximum permitted density may be increased to 13 du/ac provided all detached single family structures are proposed. In order to calculate net density, private access easements and sensitive areas subject to the City's Critical Areas Regulations must be deducted from the gross area of the property. The property appears to contain wetlands (a total of 3—with 2 considered exempt), as well as area to be dedicated to right-of-way and to be used as private access easements serving 3 or more lots. (Based on the City's definition of "critical areas," coal mine hazard designated areas are not typically deducted for purposes of calculating net density). With the applicable deductions, the proposal for 50 units on the net 7.8-acres (340,231 square feet) site would result in a net density of approximately 6.4 du/ac. As proposed, the project would not comply with the required density range of the R-10 zone. However,the R-8 zone allows the reviewing official to make exceptions from the minimum density requirements if the applicant is able to either demonstrate that the creation of additional lots is precluded by physical constraints on the property, or through shadow platting to show the -potential for creating lots that would achieve the required density. Due to the number of physical constraints on the site, staff will likely support a reduction in the required minimum density for the project. Development Standards: The R-10 zone permits only one residential structure per lot with a maximum of 4 units per structure provided the density requirements are satisfied. Detached Cedar Avenue Preliminary Plal Pre-Application July 25,2002 Page 2 of 2 accessory structures are permitted at a maximum number of two per lot at 720 square feet each, or one per lot at 1,000 square feet in size. Lot Size and Dimensions —The R-10 zone requires a minimum lot size of 3,000 square feet for detached and semi-attached structures. For detached lots, a minimum width of 30 feet and a _ _ minimum lot depth of 55 feet is required. Individual lots sizes and dimensions were not provided -- on the submitted plan, however it appears'as though the plat generally complies with the R-10 lot standards. Setbacks — Setbacks are measured from the property lines to the nearest point of the structure and must be landscaped. The required setbacks in the R-10 zone are 20 feet in the front, 15 feet in the rear, 10 feet on side yards along streets, and 5 feet on the interior side yards for attached units. The formal short plat submittal will need to include building envelopes depicted on the drawing in order to demonstrate compliance with the R-10 setbacks. Building Standards — The R-10 zone restricts building height to 30 feet and 2-stories. For detached units, lot coverage by buildings is limited to 70% and total impervious area is limited to 75%. Sensitive Areas: Based on the City's Critical Areas Maps, the subject site appears to contain Coal Mine Hazards, Wetlands, and possible Sensitive Slopes. The formal land use application will need to include a detailed slope analysis for areas within 50 feet of the property's boundaries, a Wetland - -- delineation and report, as well as a Geotechnical report that specifically addresses past coal mine activities and potential hazards on the property. Sensitivity to, as well as knowledge of, the sensitive areas located on the property to the south, which 'has received preliminary plat approval (Sunnybrook/LUA-01-127) is recommended. Permit Requirements: In addition to Environmental (SEPA) Review and Preliminary Plat approval, the proposal requires Hearing Examiner Site Plan review due to its location within the R-10 zoning designation. The review of these applications would be process concurrently within an estimated time frame of 16 to 20 weeks. After the required notification period, the Environmental Review Committee would issue a Threshold Determination for the project. When the required two-week appeal period is completed, the project would .go before the Hearing Examiner for a recommendation to the City Council on the Preliminary Plat and a decision on the proposed Site Plan. The Hearing Examiner's recommendation and decision, aswell as the decision issued by the City Council, would be subject to two-week appeal periods. The Preliminary Plat, Environmental (SEPA) Review, and Hearing Examiner Site Plan application fees would total $3,500, plus $0.37 per mailing label required for notification to surrounding property owners within 300 feet of the site. The applicant will be required to install a public information sign on the property. Detailed information regarding the land use application submittal requirements is provided in the attached handouts. Once Preliminary Plat approval is obtained, the applicant must complete the required improvements and satisfy any conditions of the preliminary approval before submitting for Final Plat review. The Final Plat process also requires City Council approval. Once final approval is received, the plat may be recorded. The newly created lots may only be sold after the plat has been recorded. Fees: In addition to the applicable building and construction permit fees, the following mitigation fees would be required prior to the recording of the plat (under R-1 or R-5 zoning). Credit for the two existing residences would be given. • A Transportation Mitigation Fee based on $75 per each new average daily trip attributable to the project; • A Parks Mitigation Fee based on $530.76 per new single family residence;and, • A Fire Mitigation Fee based on $488 per new single family residence. A handout listing all of the City's Development related fees in attached for your review. cc: Jennifer Henning Documentl\ CITY OF RENTON ECONOMIC DEVELOPMENT NEIGHBORHOODS, AND STRATEGIC PLANNING MEMORANDUM DATE July 24,2002 TO: I Lesley Nishihira 6ca C/ FROM': RebeLind STAFF CONTACT: Don Erickson SUBJECT: Buttar Preliminary Plat Pre-application, 3500 Block of Cedar Avenue S.;PRE 02-054 The applicant is proposing to develop an environmentally constrained 9.92-acre site with 50 single-family lots. A portion of the site is underlain by an old.coal mine running diagonally from its northwest corner to its southeast corner. This feature has constrained a portion of the site from future development. It also has a portion of a Category II wetland in its southwestern corner. These constrained coal mine areas would be retained either as open space or roadway. In response to concerns about the development potential of the western 4.8 acres of this 9.92-acre site, the City changed the land use designation of this area from Residential Single Family to Residential Options in'the fall of 1999. At or about the same time the City rezoned the 4.8'acres from Rf 8 to R-10. As a result, the whole 9.92 acres is now zoned R-10. At the time the property owner suggested that due to sensitive areas and coal mine hazards the development capacity of the site was 36 units. Relevant Comprehensive Plan.Obiectives/Policies: Policy LU-41. Provision of small lot single family detached unit types, townhouses and multi- family ;structures compatible with a single family character should be encouraged provided that density standards can be met. Policy LU-43. Central place- public amenities should function as a focal point within the development and 'should include features such as a public square, open space, park, civic or commercial uses. The central place should include passive amenities such as benches and fountains, and be unified by a design motif or common theme. Policy !LU-48. Buildings should front the street rather than be organized around interior courtyards or parking areas. Policy LU-51. The net development densities should be 10 dwelling units per acre. If 100% of the dwelling units.are detached, a density bonus may be allowed to a maximum of 13 dwelling units per acre. I -_ Policy LU-52. Minimum net development densities should be 7 dwelling units per acre. Policy LU-55. Development standards should reflect single family neighborhood characteristics such as ground-related orientation, coordinated structural design,and private yards. • Buttar Preliminary Plat Pre-apr.ication 2 07/24/02 Analysis: The subject proposal consists entirely of single family detached lots, which should be compatible with a single-family character (Policy LU-41). However, the density standards of 7-10 du/net acre are not met. Regarding Policy LU-43, a central place public amenity has been provided in the form of a park like open space over the"high coal mine hazard" area. Presumably, the hazard is not so great to preclude passive recreational activities here such as sitting and walking. Whereas the majority of lots appear oriented to the 42 foot paved street; 18 lots only front on a private driveway easement (Policy LU-48). None of these lots, however, are organized around interior courtyards or parking areas. Even with exclusions from the gross site area for street right-of-way, private drive access easements, and wetlands, the proposed project fails to meet the minimum net density of 7 dwelling units (lots) per net acre (Policy LU-51). The project is close, however, achieving a density of 6.4 dwelling units per net acre. By utilizing smaller lots the applicant should easily be able to achieve the minimum density. The existing average lot size is 4,000 square feet, whereas the code allows detached dwellings to have lots as small as 3,000 square feet, and with attached townhouses the minimum lot size reduces to 2,000 square feet. It is too early to determine whether this new neighborhood will have single-family characteristics such as ground related orientation, coordinated structural design, and private yards. Recommendation: Support this proposal with the caveat that the applicants reduce lot sizes as necessary to achieve the minimum density of 7.0 dwelling units per net acre or provide attached units as was the intention at the time of Comprehensive Plan amendments in 1999. In addition, staff are recommending that a 10-foot wide pedestrian easement be provided between lots 35 and 36 to ensure public access into the central open space (Policy LU-43) for lots located in the eastern portion of the development.

An environmental impact statement(EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal(and to reduce or avoid impacts froth the proposal,if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applicants: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant,requiring preparation of an EIS. Answer the questions briefly,with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases,you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer or if a question does not apply to your proposal,write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations,such as zoning, shoreline,and landmark designations. Answer these questions if you can. If you have problems,the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist'for nonproject proposals: (A nonproject proposal includes plans,policies and programs where actions are different or broader than a single site-specific proposal) Complete this checklist for nonproject proposals, even though questions may be answered "does not apply". IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions, the references in the checklist to the word "project", "applicant",and "property or site" should be read as "propossal," "proposer",and "affected geographic area," respectively. \( PA4l fik $® • 01052vSPPA01; 10/29/2002; Page: 1 • a a A.

General description of the site (circle one): Flat,rolling, hilly, steep slopes,mountainous other "The Buttar Property is located along a west-facing hillside above the Green River valley. The ground surface slopes down from east to west from about elevation 329' along the east property line to about Elevation 174'along the west property line. The ground surface is relatively even-surfaced with slopes ;ranging from eight to 15 percent grade in the east portion of the site,then steepens to about an 18 to 27 percent grade in the central portion of the site,then flattens to a nearly level to eight percent grade in the western portion of the site." (Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation,Page 3) b. What is the steepest slope on the site (approximate percent slope)? The steepest slope is approximately 27%located in the central portion of the property. c. What general types of soils are found on the site (for example, clay, sand, gravel,peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the Geotechnical Engineering Evaluation prepared by Icicle Creek Engineers the surficial geologic materials in the project area consist of fill deposits and glacial sediments. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Yes,according to the Coal Mine Hazard Assessment and Geotechnical Engineering Evaluation prepared by Icicle Creek Engineers no sinkholes (collapse features caused by the subsiding mine openings or underground mine workings) were observed on the site. However,a backfilled abandoned mine 'opening was observed in the north-central portion of the site. The historic mine map indicates this was the former location of the main entry for the Spingbrook No. 2 Mine. Two other mine openings are located in this area,but are backfilled. The ground surface has previously been leveled so the entries are not visible. No other ground subsidence features,such as linear sags in the ground surface parallel to the underground mine workings,were observed. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The purpose of the grading is to construct the new public right-of-way,the proposed private access easements, and to provide building pads and utility locations for the single-family residences. The grading is intended to be balanced onsite. The quantities of the cut and fill that will occur on site are approximately 5000 cubic yards. If it is discovered that the site will need fill materials,a fill source statement will be submitted at that time. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Erosion could occur as a result of denuded soil during and immediately following storm events. 01052vSEPAO I; 10/29/2002; Page:4 g.
