The site is a narrow parcel of undeveloped waterfront property that was created by fill for the previous industrial use of the site. The fill resulted in angular projections and steep banks into the lake. In many locations rubble such as concrete and lumber are exposed and much of the site supports only sparse vegetation due to the glanular, infertile nature of the fill . The goal of the development is to serve the recreational needs of Renton citizens through the development of as natural a waterfront and shoreline park as possible with associated improvements and activities not possible in other park areas. This goal will be accomplished through: • Improvements to the existing swimming park to relieve overcrowding, parking and circulation problems. • Development of over one mile of Lake Washington shoreline in a manner that enhances its natural and environmental potential while providing significant unstructured recreational uses. • Expansion and improvement of the water-related activity through the expansion of boat launches, landings, day moorage, overwater piers and protected water. • Development of necessary service buildings for the purpose of recrea- tion and maintenance. Construction of the first phase would begin in the summer of 1980 and would be completed by the end of 1982. The proposed project is further described in the fold-out plan map on the following page. 3 SUMMARY OF ENVIRONMENTAL IMPACTS Topography, Geology and Soils The extension area would be extensively graded to reshape shoreline areas to create a more natural , sloping shoreline. Small areas of fill (totaling approximately one acre) would be utilized to eliminate existing, artifi- cially angular projections into the lake, and to improve functioning of the boat launch. Shoreline grading and fill operations could result in turbidity and silta- tion of Lake Washington adjacent to the site. Several mitigating measures are identified to control shoreline erosion and minimize turbidity and sil- tation of the lake. Water There may be an increase in stormwater runoff from the site due to increased impermeable surfaces. Siltation of the lake may occur due to construction activity along the shoreline. Water quality within the existing drainage ditch would be improved because of the proposed relocation of the ditch, inclusion of an oil/water separator and settling basin, shading and by aera- tion from the proposed weir. The Parks Department will cooperate with Public Works to assure that the proposed settling basin and oil/water separators are constructed. Vegetation Several existing dominant groups of trees and shrubs have been incorporated into the master plan and would be retained. Much of the site would be cleared and all disturbed areas would be planted following recontouring. An area of marsh vegetation would be established along the relocated drainage ditch at the south end of the expansion area and adjacent to the beached barges at the north end of the expansion area. Wildlife Diversity and extent of upland wildlife habitat would be slightly reduced due to regrading and planting of the site. Fish habitat (salmon) would be improved by elimination of angular projections from the shoreline created by previous fill . Fill projections associated with the boat launch may create minor disruptions to juvenile salmon migration causing confusion and in- creased predation. The Department of Fisheries' approval and a hydraulics permit will be required prior to any construction activity within the lake or drainage ditch. 7 Proposed entrance and internal circulation improvements and the addition of a second entrance would improve traffic safety associated with the park. Public Services There would be a significant increase in recreational services offered by the Renton Park Department. Additional funds would be required annually for maintenance and operation of the expanded facility. Energy Increased supplies of energy would be required for the proposed construction and continued operation of the facilities. Increased fuel consumption by recreationists at the site would be offset by reduced fuel consumption in other areas. Visitors would not be using energy at home, while at the park, and the facilities would be closer to the homes of users than other beach parks in the region. Utilities A slight increase in demand for utilities would result in insignificant impacts to utility systems. Health No conditions would be created by the proposed development which would create health hazards to visitors at the site or to surrounding residents. Public safety would be improved by improvements to the traffic system, stronger separation of the swimming beach and boat launch, and by regrading of the existing steep shorelines to gentler slopes. The expanded park would be of direct benefit to public health providing a new opportunity for active recreation. Aesthetics Aesthetics of the site would be improved by recontouring of the artificially flat fill surfaces and by extensive planting. Several provisions would be made for public enjoyment of lakeside views. Recreation There would be a significant increase in the types of recreational activities and use of the site. Existing conflicts between user groups would be reduced by physical separation of activities. Archaeology/History There are no known archaeological or historical resources, and impacts due to the proposed project are unlikely. 9 No-Action A decision not to approve the proposed development would leave the site in its existing state and prohibit recreational use of the land as designated by the Comprehensive Plan. The major result of no action would be to prevent or delay all of the environmental impacts discussed in this document from occur- ring at the expansion site. Less Intensive Development If the amount of fill required for development or the number of facilities and structures were reduced, there could be lower construction and mainte- nance costs to the City than the current proposal . Infinite adjustments could be made to the proposed park extension, such as no fill and no overlook tower or multi-purpose building, fill and dredging only at the boat ramps with no stream relocation, fill only to smooth existing angular projections into the lake, or no boat ramp expansion. Any of these less intensive alternatives would have approximately the same overall impacts. The City expenditure for construction and maintenance would be somewhat less if fewer facilities are constructed. Fish movement would not be improved from existing conditions without fill to smooth out the shoreline; however, fish movement might be slightly improved by elimination of the proposed fill associated with the boat launch ramp. Alternative Location There are no comparable areas of undeveloped shoreline along the south end of Lake Washington that would be suitable for park development. Virtually the entire shoreline is intensively developed for residential , commercial , or industrial use. Development away from the lake would not allow the water-oriented views and activities associated with the proposal . Existing park congestion and con- flicts would continue to become worse. UNAVOIDABLE ADVERSE IMPACTS Geology and Soils Decrease in soil permeability due to buildings, paving and compaction. Repo- sitioning and overcovering of soils. Water Possible increase in stormwater runoff volume. Temporary, slight turbidity and siltation associated with fill . 11 Description of the Proposal NAME OF PROPOSAL AND SPONSOR The City of Renton Department of Parks and Recreation is proposing to con- struct an extension to Gene Coulon Memorial Beach Park. LOCATION The park is located on the southeastern shoreline of Lake Washington within the city limits of Renton, Washington. The park is adjacent to and would be an extension of the existing Gene Coulon Memorial Beach Park as shown in Figures 1 and 2. OTHER AGENCY FILE NUMBERS None. CONSTRUCTION SCHEDULE It is anticipated that the first construction would be initiated in the summer of 1980 with completion by the end of 1982. Waterfront work would be completed during summer and early fall in compliance with Department of Fisheries' requirements to avoid potential impacts to spawning salmon. MAJOR PHYSICAL AND ENGINEERING ASPECTS The proposed plan for the extension area is illustrated in Figure 2. The extension area includes approximately 30 acres in a narrow shoreline strip extending northward a mile from the park (15.3 acres are above water and 14.1 acres are below water) . The site is undeveloped waterfront property that was created by fill for the previous industrial use of the site. The fill resulted in angular pro- jections and steep banks into the lake. In many locations rubble such as concrete and lumber are exposed and much of the site supports only sparse vegetation due to the granular, infertile nature of the fill . The goal of the development is to serve the recreational needs of Renton citizens through the development of as natural a waterfront and shoreline 13 a park as possible with associated improvements and activities not possible in other park areas. The major elements include expansion of the existing boat launch ramp, addi- tion of a second vehicular access from Lake Washington Boulevard, internal pedestrian and vehicular circulation, day moorage for boats, picnic shel- ters, concession and restroom buildings, fishing piers, a fixed-pier wave- break, and fill , grading, and planting of the site. The entire shoreline will be regraded to eliminate abrupt dropoffs while minimizing offshore fill . The land will be contoured into a series of earth mounds. Two additional shelters and an observation tower will be located on these earth mounds with views of the rowing area and Lake Washington vistas from Mount Rainier to Mercer Island. A fishing pier with shelter would provide all-weather angling opportunities for all ages and for the handi- capped at the north end of the park. Three fishing piers and restrooms are planned, with some piers using existing pilings if future tests prove them to be structurally adequate. Over 1.5 miles of paved walking and jogging trails will be provided along the shore and through wooded glades connecting picnic shelters, fishing piers and other facilities. The boat launch will be improved and enlarged with four renovated ramps provided with side piers to allow tie-up space for boats waiting to be loaded. The ramps would be wide enough to permit simultaneous use by two vehicles during peak hours. Eighty-three drive-through spaces will be pro- vided to minimize the need to back trailers, and an additional twenty-five spaces for overflow parking will be provided. The boat launch facility will be developed so that it could remain open twenty-four hours a day, with moorage for a police boat provided along an extension of the existing pier. The "Waterwalk", an interconnected series of piers, allows people to walk well out onto Lake Washington. Three shelters will allow year-round enjoy- ment of the walk for fishing, viewing and picnicking. It would enclose an area of water for rental rowboats, and other related small craft. This area also connects to an adjacent water area along the northern half of the park, protected by a log boom where more room is available for beginning sail- boaters and other quiet water training needs. Access through the boom will be provided at both ends. In keeping with the park purpose of providing essentially passive shore- related recreation, the overall character of the park would be informal and 16 natural-appearing. Heavy use areas near the boat launch and multi-purpose building would be irrigated and carefully maintained. However, as one walks north along the shoreline the landscape would become more natural by degrees with increasing emphasis on lower maintenance materials. Fencing and screen planting will separate the park from the adjacent railroad. A new main- ` tenance facility will provide needed equipment, materials storage and a work area. The proposed plan would provide for separation of boaters and swimmers through a redesigned entrance road and separate parking areas. A substantial berm would visually separate the swimming beach area from the boat launch area. The separation would be further emphasized by relocation of the existing drainage ditch. The existing drainage ditch would be moved to the southwest side of the boat launch. The water quality within the ditch would be improved by construction of a settling basin and an oil/water separator above the park. The proposed channel would be designed to appear as a natural stream bed incorporating a marshy area and instream islands and would flow past one of the existing picnic shelters. >r bn: The use of the northern portioni24o04i'po&tension area would be more passive. Development would consist primarily of open spaces, walkways, small fishing piers, a picnic shelter, an overlook tower and two small parking areas. Two barges would be beached to recreate a feeling for the historical use of the site which was water-oriented and industrial (see ARCHAEOLOGY/HISTORY section) . Lake fill for the entire project would consist primarily of several small areas to "round-off" the angular fills that were created by the previous industrial use of the site and to provide a more natural appearing shoreline. Additional fill is proposed adjacent to the boat launch to improve func- tioning and safety and to provide a physical and visual separation between the existing swimming beach and the boat launch. A total of approximately one acre of surface area would be filled. The entire plan represents a scaling down of the number of facilities and the quantity of fill proposed in the original master plan prepared for the extension area in 1976. Fifteen acres of fill were originally proposed for the park. The presently proposed park extension represents a commitment to 17 I , Existing Conditions, Environmental Impacts and Mitigation ■ Elements of the Physical Environment TOPOGRAPHY Existing Conditions The site is essentially a flat shelf several feet higher than Lake Washington with steep banks. This topography is the result of fill and grading for the previous industrial use of the site. There are only minor variations in topography throughout the site. Environmental Impact The proposed plan recommends minor regrading throughout the site. The banks along the lake would be cut back in several locations to create a more gradual , natural and accessible slope to the shoreline. The material from the cuts would be placed in other areas to create mounds, adding variety and providing views as well as providing more secluded spaces in the cut areas. Approximately 65,000 cubic yards of material would be repositioned within the site. No need for significant quantities of imported fill is antici- pated. Proposed fill within the lake is discussed in the following section. GEOLOGY AND SOILS Existing Conditions A geology and soils engineering consultant was engaged to evaluate soil conditions of the site. Onshore test pits and borings and offshore borings were utilized to identify existing conditions (see Figure 3) . The full report of the findings is available for review at the Renton Parks and Recreation Department. A summary is presented here. The portion of the proposed park expansion, presently above lake level , has all been developed by previous filling and is nearly level . The property was previously used as a cargo transfer area, and log storage area as suggested by the numerous piles driven offshore. The lakeshore itself is characterized by a line of logs and timbers, large concrete blocks, some quarry stones, and considerable miscellaneous debris. The shoreline generally is steep, and appears to be subject to active undercutting by wave action. Immediately offshore are a series of pile clusters and submerged concrete blocks and metal service ladders. 19 The onshore borings encountered very loose to medium dense, gravelly, sandy fill to depths of 12 to 18 feet. Underlying the fill in the borings are medium dense to dense, saturated, fine to coarse sands with gravel . Boring number 2 had approximately 4 feet of peat beneath the fill , followed by very loose to loose sand and gravel grading to medium dense, silty, fine to medium sand and gravel at 36 feet. Although massive rubble was not encountered in the borings, exposures along the shoreline indicate that large quantities of wood, concrete, bricks, and other materials may be present. At the offshore boring locations, very loose to soft sand and silts were present to depths of 13 feet. Underlying these soft, saturated soils are medium dense to dense, saturated, fine to medium sands with gravel . The offshore soils are characterized by surficial , very loose to loose, and soft materials to depths about ten feet below mudline at the borings. Closer to r.e shore, the near-surface muds and soft soils are approximately one to three feet deep. Groundwater at the onshore boring locations was encountered at approximately ' 7 feet. The groundwater table is probably at lake level near the shoreline. Some borings indicate rises with increasing distance from the lakefront. In addition, the fill probably has lenses of permeable soil containing perched or trapped water. Also, the silty areas, that appear in the fill , trap water at the ground surface and result in ponding during wet weather. Environmental Impact Onshore clearing and grading, within the areas already filled will expose rubble or debris which should be covered by soil . Clearing and grading will result in minor, temporary increases in erosion potential . Due to the silty nature of the on-site soils, proper compaction will be difficult or impossible when the soils are more than a few percent above their "optimum moisture" content. Periods of warm, dry weather are the most desirable condition for a successful filling program. If filling is required during periods of wet weather, the fill should consist of clean sand and gravel . Clean sands and gravels are not normally moisture sensitive, and can usually be compacted under a variety of climatic conditions. Mounds rising up to 20 feet above surrounding grade are proposed for two locations in the park. Because of the weak nature of the subsoil , these 21 In the southern portion of the park where a steep or near vertical bank is planned, a rip-rap bank covered by a walkway would be constructed with provision for daylighting the water below to allow fish passage. To the north, "sliver beaches" and minor shoreline modification have been planned. Water depths of about 6-15 feet are present near areas where existing park grade is some 3-6 feet above lake elevation. In these areas, it would be appropriate to excavate the above-water portion of the park shoreline downward to the lowest practical elevations to minimize the poten- tial for erosion and shear failures or mud displacement beneath the water surface. AIR Existing Conditions The Gene Coulon Memorial Beach Park is 'part of the Puget Sound basin and has a typical northwest Pacific Coast marine climate. Temperatures are mild and precipitation moderate, with the majority of rain occurring in the winter months. Winds are generally southerly during the winter and northerly during the summer. Temperatures in the area vary from a monthly average of 40°F (4°C) in January to 65°F (17°C) in July. The annual average temperature is about 50°F (10°C) . Precipitation can vary from 25 to 65 inches (64 to 165 cm) , but averages about 45 inches (114 cm) annually. Snow occurs occasionally during the winter but rarely lasts longer than two or three days. . Winds are of moderate speed with the prevailing direction generally south- westerly. It is expected that winds at the park will be out of the south to southwest during the winter months and out of the north to northwest durin the summer. g Meteorology creating the "worst case" air quality conditions is most likely to occur for several days during the late winter months with overcast skies and light southerly winds. Localized inversions can occur under northerly winds during the late summer and fall months, but usually disperse each afternoon. The air drainage condition associated with stagnant air will flow generally from the hill westerly towards Lake Washington. The expansion site is located within the Puget Sound Air Pollution Control Agency non-attainment areas for carbon monoxide, oxidant and particulate 23 • TABLE I SUMMARY OF POLLUTANT CONCENTRATIONS RENTON AREA Particulate Matter (ug/m3) Location 1978 1977 1976 1975 Standard S.E.

However, this would be confined to the area under construction and would cease upon completion. Watering procedures and good operational techniques should keep dust levels to a minimum. Mitigating Measures Dust resulting from construction work can be minimized through the use of good operational techniques such as watering of exposed areas. Puget Sound Air Pollution Control Agency regulations require that precautions be taken to minimize the entrainment of dust in the ambient air. 25 any collection of aquatic life from the ditch for human consumption should be discouraged until water quality is improved. A settling basin and oil trap has been suggested for the ditch on adjacent property but it is not part of the present proposal . The settling basin would remove silt and many heavy metals. The oil trap would be necessary to prevent oil slicks which may remain in the proposed marsh for longer periods than in the present ditch due to increased surface area and slower moving water. Any construction activity within the drainage ditch will require a Hydraulics Permit and Department of Fisheries approval . Mitigating Measures Silt traps and oil/water separators for the on-site storm sewer system would be incorporated within all catchbasins in parking lots or roadways. These devices will remove oil products, silt and many heavy metal compounds before the stormwater enters the lake. The effectiveness of such devices is entirely dependent on routine maintenance. The responsibility for maintenance would be placed with the Parks Department. Frequent sweeping of the streets and parking areas could also significantly reduce impacts to runoff quality by reducing silt, litter and some of the heavy metals and nutrients. Use of fertilizers, herbicides, and pesticides on the site should be carefully controlled to minimize the excess nutrients or poisons washing into the lake. The settling basin and oil/water separators suggested for the drainage ditch would improve the appearance of water within the proposed marsh area. Estab- lishment of tall vegetation along the banks of the ditch would shade the water and might result in reduced water temperatures which would be favorable to fish life. Frequent sweeping of city streets and the expansive industrial parking lots where paved would also improve the quality of water within the drainage ditch. The quality of water within the ditch should be monitored periodically due to potential human recreational use and consumption of aquatic life. VEGETATION Existing Conditions The site was previously cleared and graded for industrial use, but not paved. Thus, the entire site is in the early stages of vegetation succession. The 27 Mitigating Measures Mitigating measures that are incorporated in the proposal include the follow- ing. 1. Retention of existing shrubs and trees in areas where grading is not proposed. 2. Replanting of all areas upon completion of construction. 3. Construction in phases so that entire site is not stripped of vegeta- tion at one time. 4. Creation of a new marsh habitat. 5. Creation of several areas of shrubs and trees that will be allowed to grow essentially in a natural condition. These would be located generally in the northern portion of the park. WILDLIFE Existing Conditions Information related to wildlife use of the site was obtained from several sources. A thorough study of aquatic biology in the vicinity of the park was _ conducted in 1975 and 1976 for the Puget Sound Power and Light Company. A subconsultant (Nautilus Association) was hired by Jones & Jones in 1979 to further investigate aquatic and terrestrial biology of the park expansion area. The results of these investigations were supplemented with site visits during preparation of this Draft EIS. Terrestrial habitat of the site consists of grassy areas, shrubby areas and tree groves all in early stages of succession following industrial use of the site. When compared to more natural shorelines, the edge effect along the lake shoreline is of limited value because of prior disturbances and indus- trial use. Only two locations have dense shrubs along the lakeshore, the area immediately east of the boat launch ramp and a small area near the proposed location for the beached barges. Terrestrial wildlife populations are correspondingly limited and comparable to most undeveloped suburban land. The lake provides habitat for waterfowl and fish populations. Waterfowl include migratory and resident wild bird populations, and resident domestic breeds. Fish species are abundant and diverse in the waters of the park. Over twenty species of fish were captured in or adjacent to the park during the Puget 29 gradual slopes and granular fill proposed should minimize impacts to sockeye salmon. Pile-driving in the lake could damage salmon eggs within shoreline gravels. Angular projections such as those proposed adjacent to the boat launch con- fuse juvenile salmon migrating along the shoreline and may force them into areas of increased predation. In contrast, the curved areas of fill proposed .�� in several locations north of the boat launch may improve conditions by eliminating existing angular projections of fill and the resulting steep shorelines. The proposed piers and breakwaters will be designed to permit passage of fish along the shoreline. The proposed marsh along the existing drainage ditch and surrounding the barges will result in additional habitat; however, intense human activity and lack of surrounding habitat immediately adjacent to the small marsh area may limit wildlife use of the marsh to common, relatively tolerant species. In winter, when human activity is reduced, this area may become attractive to wintering waterfowl , particularly those species that may graze on the adja- cent lawns. Impacts of the proposed construction to waterfowl habitat should be relatively minor. Mitigating Measures Allowing the vegetation within the expansion area to grow essentially wild with a minimum of maintenance (mowing, weeding, pruning) would improve the quality of terrestrial wildlife habitat. Planting trees and shrubs along the shorelines of the lake and drainage ditch would reduce shallow water tempera- tures and improve conditions for aquatic life. The inclusion of food- producing species would further improve the value of the proposed plantings for wildlife. Any measures to minimize water quality impacts would also benefit wildlife. Elimination of the proposed fill areas projecting into the lake adjacent to the boat launch ramp would improve migration movement of juvenile sockeye salmon along the shoreline. To meet Department of Fisheries regulations, all pile-driving should be conducted between the months of July and October to avoid potential impact to incubating salmon eggs. 31 WG NOKTN ej _ // _ I i \--.\\-- ---.... 1 e"\,,,:;,.....,.... ...........00'.....,....'"".... •••:7 .

According to EPA criteria, there will be only a slight increase in noise levels due to the proposed expansion. Three dBA is the required increase before the human ear can detect a significant change in noise levels. Since the increase in traffic is confined principally to daytime hours on weekends and in summertime, the late night noise levels will remain essentially unchanged from existing levels. The area will remain in compliance with state standards. • There will also be a short-term increase in daytime noise levels due to construction activity. (For information on construction noise levels, refer to APPENDIX.) Noise from construction activities will generally range from 69 to 95 dBA, with some higher peaks if impact equipment is used. Con- struction noises around the site will cease upon completion of the project. Mitigating Measures Long-term mitigating measures are difficult to implement because the princi- pal noise increase is due to traffic generated by the site expansion. The noise levels predicted are based on the traffic generation predicted by the City of Renton. Noise abatement procedures during construction could include: - The use and maintenance of properly operating mufflers and quieting devices; - The use of quietest available machinery and equipment; - The use of electric equipment in preference to gas, diesel or pneumatic machinery; - Locating construction equipment as far from nearby noise sensitive pro- perties as possible; - Shutting off idling equipment; - Limitation of construction hours to coincide with the normal workday period (e.g. 8:00 AM to 6:00 PM) . NATURAL RESOURCES The vacant land designated for the park expansion has no significant value as agricultural land or as a source of mineral or timber resources. The site would be converted to public use for the foreseeable future. Much of the dominant natural vegetation of the site would be retained and the more desirable species would be encouraged. 35 • 0,,. 11 . 1.1.I.hF'I�hk+I , - , i Iiii r�Y rg; ! •.

Single-family residences adjoin the site to the north and extend along the eastern side of Interstate 405. The western edge of the expansion area is coincident with the shore of Lake Washington and was formerly used as an area for log shipping and storage. The Shuffleton Power Plant, a steam-generating plant operated by Puget Sound Power and Light Company, is located at the southwest corner of the park, and the large plant buildings and parking lots of the Boeing Company and Pacific • Car and Foundry occupy the area south of the park. Zoning Single-family residential (GS-1 and G) is the zoning designation for the existing park, and heavy industry (H-1) is specified along the lakeshore extending northward as shown in Figure 6. Heavy industry zoning also covers the entire area south of the park. A small area of B-1, business use, is applied to a trailer storage business located east of the park entrance and this is adjoined by a multi-family residential (R-4) area. The remainder of the land around the east and north sides of the park is zoned single-family residential (G-6000) except for a trailer park (T) and a public use (P-1) zone. Environmental Impact The expansion of recreation use in the area north of the existing park would be consistent with the land use policy of the City of Renton. Development of park facilities and access would alter vacant land and convert it to passive recreational use. Land use patterns in the adjacent areas would not be expected to change, and no significant impact to land use is expected due to the expansion. Recreational development would be permitted under the present zoning desig- nation (G and H-1) and therefore, no zoning change would be necessary. 39 ■ Elements of the Human Environment POPULATION AND HOUSING Existing Conditions The Gene Coulon Beach Park is located in Census Tract 253, shown in Figure 7, which is coincident with PSCOG' s AAM District 3820. For purposes of com- parison, the area was analyzed (see Table IV) to assess the characteristics and growth trends of the population closest to the site, as well as the City of Renton and King County as a whole. Table V shows the projected area growth for the surrounding AAM Districts as compared to the County, and Table VI shows the housing characteristics. The housing information is collected from the 1970 Census tables and is therefore ten years out-of-date (especially note dollar figures). Environmental Impact The proposed park expansion is not expected to have a significant effect on existing population or housing characteristics or trends. Visitors to the park mostly live in southern King County, and as these areas grow in population, the park visitation figures are expected to increase proportionately. The park expansion itself, however, is not expected to draw a significant increase of new people or housing to the Renton area. TRANSPORTATION/CIRCULATION Existing Conditions The City of Renton Traffic Engineering Division has reviewed the proposed park expansion and has provided the following information related to traffic. Access to the park is provided by both Lake Washington Boulevard with vehicular access at the south end, and by water (Lake Washington) for pleasure boat users. Most boat users arrive at the park by means of the street system, so this section will concentrate on automobile traffic on adjacent streets and within the park. The capacity of Lake Washington Boulevard at Level of Service "C" is 1,200 vehicles per hour. The 1979 Average Daily Traffic (ADT) is 6,000. Peak hour traffic demand on Lake Washington Boulevard occurs on weekdays between 6:30 and 8:00 AM and between 3:30 and 5:00 PM. The projected 1990 ADT without the proposed park expansion is 8,200. The present two lanes are scheduled in the 41 TABLE IV POPULATION CHARACTERISTICS AND TRENDS AAM Districts: 4000 3850 3860 3820 3840 3830 Renton King County Census Tracts: 247 250 251 252 254 255 253 256 257 258 1970 Population 6,416 5,230 4,156 4,968 4,840 3,036 5,917 3,558 3,488 12,300 25,258 1,159,230 1978 Population* 6,824 5,462 4,628 4,692 4,401 2,754 6,056 3,567 4,871 11,906 29,300 1,186,903 AGE 0-9: 22.3% 23.1% 25.1% 23.5% 18.5% 23.7% 13.4 27.3% 23.0% 26.9% 19.6% 17.6% 10-19: 21.5 25.0 20.9 20.0 16.3 20.6 15.8 16.5 16.2 19.8 17.2 18.7 20-34: 20.1 16.8 25.4 23.7 25.4 23.8 22.0 28.6 30.5 27.1 25.1 22.9 35-64: 33.6 33.0 25.6 27.6 30.2 29.3 35.6 24.7 27.2 24.4 30.5 32.0 w 65+ : 2.5 2.1 3.0 5.2 9.6 2.6 13.2 2.9 3.1 1.8 7.6 8.8 SEX % Female: 49.7% 49.6% 48.9% 50.6% 53.5% 49.7% 51.0% 49.4% 50.8% 49.8% 51.0% 51.1% RACE % Black: 1.1% 1.0% 1.6% 0.5% 0.5% 1.5% - 2.0% 0.6% 0.4% 0.8% 3.5% MEDIAN INCOME ($): 14,757 16,589 11,356 11,376 10,248 11,337 10,282 11,741 12,212 12,066 11,120 11,886 Source: 1970 Census *PSCOG Estimate City of Renton's Six-Year Street Capital Improvement Program for widening to four lanes with curbs and gutters, sidewalks, lighting and channelization. The estimated construction period for the improvements is 1983-1985 although funds for the construction have not presently been identified. The improvements will increase the capacity of the boulevard to 1,500 vehicles per hour at Level of Service "C". Traffic generated by the park and using Lake Washington Boulevard fluctuates seasonally, daily and hourly. The heaviest traffic occurs on sunny, summer weekends between 11:00 AM and 12:00 Noon. The summer peak day traffic averages 2,500 vehicle trips with 10% of these occurring between 11:00 AM and Noon. Weekday peak traffic generation is also heaviest in summer with 2,000 ADT, but the peak demands occur between 12:00 Noon and 1:00 PM, and between 5:30 and 6:30 PM. Thus, the peak park traffic generation does not generally coincide with peak commuter traffic on Lake Washington Boulevard. Congestion within the park occurs during peak hours and conflicts arise due to insufficient parking for boat trailers. Congestion at the boat ramp occurs primarily due to inefficient use of the ramp because of a lack of finger piers or other facilities for handling boats in the water. The park is presently served by METRO Bus Route 240. A bicycle route circling Lake Washington and serving the park has been proposed and partially imple- mented, but not within the vicinity of the park. Except for an existing pedestrian walkway from the Renton Highlands beneath Interstate 405 to the entrance, the park is not easily accessible to pedestrians due to a lack of pedestrian routes and heavy automobile traffic in the area. Environmental Impact The expansion of the Gene Coulon Beach Park is expected to increase peak day traffic generation by approximately 1,200 to 1,500 vehicle trips per day. The type of traffic and peak hour demand should remain unchanged after the park expansion. The increased traffic generation is well within the capacity of Lake Washington Boulevard without a reduction in level of service. Access and traffic safety for the park will be improved by the expansion due to 1) provision of a secondary entrance, 2) improved internal circulation includ- ing separation of parking for different park uses, and 3) provision of expanded turning lanes on Lake Washington Boulevard. 45 Patrol calls to the park deal most commonly with problems of drinking, rowdyism and noise. These problems are greatest in the early summer, as longer days and warm weather promote the heaviest use of park facilities. Problems of parking enforcement and traffic control require continous police attention during holiday weekends and Seafair week. Environmental Impact Although some pressures of overcrowding should be alleviated, expansion of the park and an increase in use could require an increase in patrolling by police and park personnel . With the requested additional personnel , there should be no problems of adequate police protection. The proposed observation tower may present opportunities for vandalism, as has occurred previously with the existing tower in the children's play area. The City of Renton pays for King County patrol boat service along the shore- line, and since the response time of the County patrol is slow, the City would like to purchase its own fire and police patrol boat. Moorage space would be provided at the park. In all cases, funding for increased services is a policy issue that must be considered by the City Council . Mitigating Measures The expansion area could provide for a separation of user groups: family groups utilizing the existing beach area and teenagers using the northern expansion area. This type of voluntary separation happens at several other beach parks in the Seattle area and could reduce any potential conflicts between the two groups (see RECREATION) . Hospitals Valley General Hospital in Hospital District No. 1 serves the areas of Renton and Kent. The hospital is operating above capacity at the present time and as a consequence, an $18 million expansion program is proposed to begin next year. One of the major areas of expansion is to be for emergency services, where demand is projected to approximately double in the next five years. There would be no significant impacts to hospitals associated with the expan- sion of Gene Coulon Beach Park and any calls for emergency treatment could be readily met. 47 The addition of four boat launch ramps would relieve some of the demand on the existing launch facility, and would provide additional access for boaters from the metropolitan areas south and east of Lake Washington (see RECREATION) . Expansion is expected to double the capacity of the site and thereby alleviate recreation demands on other surrounding parks. ENERGY Existing Conditions Energy consumption at the park is limited to electrical use for lighting and irrigation equipment and fuel used for park maintenance vehicles. Park use of electricity was 204,330 KWH in 1977 and 176,670 KWH in 1978, reflecting the conservation efforts of the Department of Parks and Recreation. Energy in the form of gasoline is also used by park patrons traveling to the site and by boaters using the launch facilities. Environmental Impact By providing recreation opportunities in the midst of a heavily urbanized area, the need to travel long distances for such opportunities would be eliminated. In addition, public transportation would be readily available, resulting in a saving of gasoline. The expanded park would require only a slight increase in energy with the addition of a multi-purpose building and lighting for parking areas and piers. Use of low-level , low-intensity lighting would mitigate the added energy costs and, with utilities already in place or nearby, the energy costs of installa- tion would be minimized. Fuel would be needed for equipment during the construction period. Energy costs associated with construction materials for paving roads, trails and parking lots is estimated to be about 5 billion Btus. Site preparation and manufacturing and transportation of materials for the multi-purpose building would require 3.6 billion Btus. UTILITIES Electricity Existing Conditions Electrical service to the park is provided by Puget Sound Power and Light Company and is the only energy source presently utilized there. An underground 49 Sanitary Sewer Existing Conditions A large METRO gravity sewerline is located along the eastern boundary of the park and an 8-inch cast iron pipe connects park facilities to this sewerline. The City is under contract with the METRO plant in west Renton for primary and secondary sewage treatment. The low elevation along the lakeshore has made the installation of two lift stations necessary, one at the south end of the park and one at the north end. Environmental Impact Only a minimal increase in demand for sewer service is expected from expansion of the park. The needs for additional connections and another lift station would be considered in the final design of park facilities. Storm Drainage Existing Conditions A deeply cut drainage ditch runs through the park. It carries stormwater that originates in the residential/industrial area between Interstate 405 and the Cedar River, plus runoff from the lowlands and hillside area southeast of the park. Erosion is a problem in the watercourse due to upstream flooding, but the depth of the ditch prevents flood problems in the park. Storm detention is required by the City of Renton when any portion of land is paved, and installation of oil/water separators are required in every catch- basin. Environmental Impact A detention pond with the necessary oil/water separators is proposed to be located just outside the southern boundary to improve water quality in the drainage ditch flowing through the park. The drainage ditch would be moved to , the other side of the boat launch and a more natural stream bed would be designed according to the proposed plan. Given sufficient funds, the City utility would construct a series of detention basins to alleviate upstream flooding. Solid Waste Solid waste removal is contracted by the City to General Disposal Corporation. The garbage is hauled to the Renton transfer station and subsequently taken to landfills in the Maple Valley and the Newcastle areas. 51 AESTHETICS Existing Conditions The expansion area is a long (nearly a mile) , narrow (50-350 feet) parcel of shoreline set against an undeveloped, wooded hillside. It is primarily a flat shelf resting several feet above the lake with fairly steep banks sloping into the lake, making access to the lake difficult. The site is sparsely vegetated due to recent disturbances related to the former industrial use. Litter, discarded lumber and concrete blocks can be found in several locations, and unused pilings occur all along the shoreline, although the pilings provide foreground reference and interest. Views from the site consist of the south end of Lake Washington with Mercer Island to the north. The developed portion of the park, the Puget Sound Power and Light power plant and the huge Boeing manufacturing buildings may be seen to the south and Mt. Rainier can be seen in the distance. Environmental Impact The overall appearance of the site would be improved, primarily due to grading and fill (resulting in a more natural appearing shoreline) and proposed land- scaping. The grading will also result in a more accessible shoreline by reducing the slopes which lead to the water's edge. A series of small bowls or shallow ravines will be created that will provide a feeling of seclusion and separate beach areas. These areas will be separated by mounds and plantings. The mounds will provide more distant views across the lake. On one of these areas, an observation tower is proposed to provide still longer views. Areas of the park will be linked by a series of walkways that will provide peaceful , quiet walks to the northern, less developed portion of the park. The fishing piers may also provide places for peaceful viewing of the lake. At the southern end, visual interest will be created by the more intense activity associated with the boat launch, boat rentals, moorage and picnic facilities. Visual and noise conflicts between the swimming beach and boat launch would be reduced by the proposed berm separating the two areas. RECREATION Existing Conditions Records of recreational use of the existing park indicate that it presently receives approximately 300,000 visitors annually. The park is a large swim- .. ming beach and boat launch with associated lawns, picnic shelters, playground 53 The proposed plan includes placement of two barges on the beach to suggest a visual tie with the historic, industrial use of the site. Vegetation would be allowed to grow around the barges and visitor access would be provided. The historical use of the site would be explained to visitors by means of inter- , pretive devices. 55 Short-Term Environmental Uses vs. Long-Term Productivity (THE RELATIONSHIP BETWEEN LOCAL SHORT-TERM USES OF MAN'S ENVIRONMENT AND MAINTENANCE AND ENHANCEMENT OF LONG-TERM PRODUCTIVITY) and Irreversible or Irretrievable Commitments of Resources Implementation of the proposal will , for all practical purposes, irreversibly commit the land area in question to the proposed use. The long-term fore- closure of future options will be offset by the short- and long-term public gains to be realized from the provision of needed park and recreation space. The land is not uniquely suited to any foreseeable alternative type of use and that proposed will serve the recreation needs of future generations. The land is not now utilized for agriculture or mineral production and does not provide unique wildlife habitat. It is unlikely that these or similar economic or environmental uses would increase in the future if the site were not devel- oped for water-oriented recreation use. Delaying implementation of the proposal until some future time would not pro- duce any anticipated environmental benefit in the long term. Delay would significantly increase construction costs and reduce the value of bond funds due to inflation. Financial , labor, material and energy resources would be irreversibly commit- ted to the development in quantities typical for comparable development. Natu- ral resources expended would include construction materials and energy sup- plies. Material commitments would include the use of water, wood, steel , gravel , glass, plastic, asphalt and cement. Energy would be expended during construction and for lighting, heating, transportation and other domestic uses. Long-term maintenance would require the commitment of funds for services such as sewers, fire protection, and the continued use of water and energy resources. The public service and facility needs of the new park would be essentially irreversible as demands on water supply, solid waste disposal , and sewage treatment would be increased requiring long-term maintenance. Certain resour- ces including non-hydro energy, building materials and land are irretrievable and must be accounted for in this and future generations. 57 Alternatives to the Proposal "NO-ACTION" A decision not to approve the proposed development would leave the site in its existing state and prohibit recreational use of the land as designated on the Comprehensive Plan. The major result of no action would be to prevent or delay all of the environmental impacts discussed in this document from occurring at the expansion site. A "no-action" decision would result in prime waterfront property left vacant, with the industrial waste and trash remaining on the expansion site. The bluffs along the shoreline would remain in their present state, presenting a safety problem to any trespassers using the site. The existing parking and traffic congestion problems at the park would continue on peak days, and likely worsen. Costs to the City of Renton for park maintenance and staff would remain approximately at existing levels (allowing for standard inflation rates) with- out expansion of the park, rather than being increased by the proposal . Con- struction costs would not be incurred. MORE INTENSIVE DEVELOPMENT A more intense development alternative was submitted to the Department of Parks and Recreation in 1976; the Lake Washington Beach Park - The Phase II Planning Program and Master Plan was adopted by the Renton City Council in April of 1977. The Plan recommended approximately 15 acres of fill (as opposed to the one acre currently proposed) and extensive shoreline modification and struc- tures (see DESCRIPTION OF THE PROPOSAL) . The facilities and structures were also more extensive, including an amphi- theatre, playgrounds, boat rental , water-ski launch and boat marina for day moorage and had a potentially greater environmental impact. The construction and maintenance costs to the City of Renton would also have been greater. LESS INTENSIVE DEVELOPMENT If the amount of fill required for development of the number of facilities and structures were reduced, there could be lower construction and maintenance 59 Unavoidable Adverse impacts Geology and Soils Decrease in soil permeability due to buildings, paving and compaction. Reposi- tioning and overcovering of soils. Water Increase in stormwater runoff volume. Temporary, slight turbidity and silta- tion associated with fill . Vegetation Elimination of some second-growth vegetation and replacement with grass, shrub and tree areas. Wildlife Possible elimination of a few common species resulting from a decrease in diversity and extent of habitat within the land portion of the undeveloped expansion area. Noise Slight change in noise patterns due to changes in internal circulation. Natural Resources Consumption of common building materials for construction of new facilities. Transportation/Circulation Increase in traffic volumes to the park. Public Services Significant increase in funding required for maintenance and operation. Energy Consumption of additional quantities of energy for heating and operation of expanded facilities, travel to and from the site, and power boat usage. Utilities Increased consumption of water and electricity requiring internal extensions of each system. 61 References Beaton, J. L. , A. J. Ranzieri , E. C. Shirley and J. B.

Noise is a physical phenomenon created primar- ily from mechanical vibration. Noise occurs in a predictable fashion where free sound radiation is governed, with minor variance, by an inverse rela- tionship (as the distance from the source increases, the sound is reduced) and its transmission is determined by the physical properties of the transmitting medium (usually air) . Man's response to noise is determined by the sound level emanating from the source of noise and the frequency spectrum of the sound. Noise intensity represents the level of sound which is weighted in accordance to the apparent loudness perceived by an average human observer. This number is expressed in "A"-weighted decibels and is written as dBA. This descriptor is the one generally accepted as having the best correlation with human judgements of loudness. Each increase of 10 dBA in the noise level is subjectively judged as an approximate doubling of loudness. Noise intensity covers such a broad range that it is measured logarithmically and noise levels usually represent a statistical average for a given period of time. Since noise is rarely steady or constant for long periods, average noise levels do not readily account for very high noise levels of very short dura- tion. For example, a long-term average of a 60 decibel (dBA) sound level over a 24-hour period might include peak sound levels of 110 dBA, but such an event might be less than one second in duration. This fluctuating noise can be described statistically by noise levels exceeded for given percentages of time during a prescribed time period. The commonly used statistical levels are L90, L50, and L10, for which the number in the subscript indicates the percentage of time that the given level is exceeded. The L90 is indicative of background noise in the absence of local noise events. The L50 is the median or "average" sound level exceeded 50 percent of the time. The L10 is usually indicative of maximum noise from recurring events, such as traffic during peak volumes. 67 The Washington State Department of Ecology (WAC 173-60) has also specified regulations relating to maximum environmental noise levels. They hve a cllassi- fied fied various areas or zones and established maximum permissible nhve These "EDNA' s" (Environmental Designation for Noise Abatement) are classified as: a) Residential area - Class A EDNA b) Commercial areas - Class B EDNA c) Industrial areas - Class C EDNA The maximum permissible noise levels for these zones are shown below. NOISE LIMITATIONS EDNA OF NOISE SOURCE EDNA OF RECEIVING PROPERTY CLASS A CLASS B CLASS C CLASS A 55 dBA 57 dBA 60 dBA CLASS B 57 60 65 CLASS C 60 65 70 Between the hours of 10:00 PM and 7:00 AM, the noise limitation of the above table shall be reduced by 10 dBA for receiving property within Class A EDNA' s. These noise levels may be exceeded on the receiving property by 15 dBA foor1.5 minutes, 10 dBA for 5 minutes, 5 dBA for 15 minutes for any one hour, day or night. The limitations suggested by the State are approximately equivalent to the Ldn levels indicated by the EPA in residential areas. Motor vehicle noise is controlled under a different standard (WAC 173-62) . Because the use of motor vehicles would regularly violate the maximum xestablished to covissible levels in the EDNA' s, additional regulations have been theState of Washington •- er this category. The following standard has been promulgated by to control the noise levels from motor vehicles: blic or "No person shall operate under any cond motor vehicle ptnonsyorugradehlloady accel- eration of such fo erati on or deceleration s nforch a themanner as category to exceed vehicle,he all measur d xat imum a w permissible sound levelhin the distance of 50 feet from the center of established the shed by the lane of travel ssi oneon limits specified, under procedure Equipment". 69 Letters of Comment to Draft E I S This section contains Letters of Comment to the Draft EIS reproduced in full .

We have the following comments for your consideration. We wish to commend you for planning to extend such a park which will increase the opportunities for public access to Lake Washington, with a minimum of serious environmental impacts. We are particularly pleased that the earlier proposal which required 15 acres of fill has been modified into the present plan. However, we do have some questions even about the currently proposed fills . It is not clear whether the fills will have gentle slopes which will create 1 some shallow water areas useful for fish habitat or whether vertical bulkheads are proposed to reduce construction turbidity. It would be useful to know how deep the water is and the total area of lake bottom __which will be covered by these fills. '—The effect of the various in-water structures on water circulation is not addressed. Adequate water circulation is necessary to maintain 2 high water quality - a very desirable goal in such recreation areas. For instance, it is unclear whether the entire "waterwalk" will be floating . Water circulation changes in the enlarged boat ramp/moorage area and by ._the piers should particularly examined. --The DEIS indicates that the shoreline within the park extension will be 3 extensively regraded to eliminate steep drop-offs. If these regrades _extend below the water surface, they should be considered as fills. 75 I '` " STATE OF DEPARTMENT OF ECOLOGY .. = ota. = % WASHINGTON Mail Stop PV-11 206/753-2800 f.' �` Dixy Lee Ray Olympia.Washington 98504 f� , Governor a January 8, 1980 John Web ley Renton Department of Parks and Recreation 200 Mill Avenue South • Renton, Washington 98055 Dear Mr. Webley: Thank you for the opportunity to comment on the draft environmental impact statement for the Gene Coulon Memorial , Beach Park extension.

Inclusion of these plans in the Final EIS would not be inappropriate. 7 [Will sewage pump-out facilities be available at the moorage areas? r What plans have been made to deal with viscera if cleaning of fish is to L occur at the park? A mitigating measure listed on page 31 states that all pile driving shall be conducted between the months of July and October. This timing requirement is designed to avoid damage to incubating eggs deposited by lake shore spawning 9 sockeye salmon. Although the use of this shoreline area by lake shore sockeye for spawning purposes may be minimal due to the fine texture of sediment, if pile driving and all fills in the lake are scheduled from July through October this will avoid turbidity induced increased predation rates upon juvenile sockeye outmigrating from the Cedar River.

Ericksen , Planning Director By : David R. Clemens , Senior Planner RE: Gene Coulon Memorial Beach Park Expansion Draft Environmental Impact Statement We have reviewed the Draft EIS for Gene Coulon Beach Park Expansion and have the following comments to offer : 1 . The City of Renton Shoreline Master Program is the primary mechanism for regulating development along the shores of Lake Washington within the City . The provisions of the Master Program supplement the City ' s Comprehensive Plan and Zoning Ordinance . Approval of a Substantial Development Permit , under the Shoreline MasterProgram and RCW 90.48 , is a prerequisite for approval of other development permits . Where existing land use plans and regulations and the necessity for securing various permits are noted in the Draft EIS (e. g. page 7, 18 and 22 ) , appropriate mention of the Shoreline Master Program should be provided . The Gene Coulon Park Expansion proposal is located almost entirely within the designated shoreline of the City of Renton . Therefore , construction of boat ramps , bulkheads , piers and docks , parking, trails and filling and stream alteration must conform with the specific use regulations of the Master Program. Construction of the piers and docks may require a variance from these regulations , which must be approved by the State of Washington . 2. Portions of the park development , specifically the floating piers , docks and log booms , extend beyond the inner harbor line and 2 out to the outer harbor line. The inner harbor line defines the City of Renton ' s corporate limits and the City ' s jurisdiction does not extend beyond. In order to accomplish development of the park in 89 INTEROFFICE CORRESPONDENCE Date December 20, 1979 TO: Warren C. Gonnason FROM: Richard C. Houghton SUBJECT: EIS Gene Coulon Park rThe water line should be extended along Lake Washington Blvd. rather than through the park. Extensions then could be made as needed into the park. 1 Also some reimbursement to the park could be derived from other parties Lconnecting to the line on the east side of Lake Washington Blvd. 2 No problems with sewers. Should be able to connect to Metro by special permit. The need for a pump station should be re-evaluated considering depth of Metro line. 3 Improvements to Lake Washington Blvd. will be necessary. Probably addi- tion of a left turn lane with lots of storage. This being really the only area on the southeast end of the lake that has 4 a boat launch facility close attention should be given to developing as many facilities for that purpose as is possible. Especially auto-trailer __parking facilities. RCH:pmp e w c.4. y r� 91 1 c\��\ � �� /,moo RECEIVE® DEC 1 a1079p -12 MY OF ➢3E'l9TON cS. PAIR:.; DEPT :1 13239 N.

Generally a good mix of evergreen and deciduous that produce berries and provide cover are the most bene- ficial . This could be accomplished in some of the passive use areas . 2 If the log-boom was made three or four logs wide, then it could provide a resting area for the water fowl that use these environs. With these slight modifications this could be a very desireable addition to the community for both humans and wildlife.

A Department of the Army permit is required for all work in navigable waters of the United States and for the discharge of dredged or fill material into waters of the United States including adjacent wetlands. Response: The City of Renton Parks and Recreation Department is aware of the Department of the Army requirements. A U.S. Army Corps of Engineers' permit is listed as a license required on page ii of the Draft EIS. COMMENT LETTER FROM U.S. COAST GUARD - DEPARTMENT OF TRANSPORTATION January 23, 1980 No comment. No response necessary. COMMENT LETTER FROM U.S. DEPARTMENT OF THE INTERIOR, FISH AND WILDLIFE SERVICE January 22, 1980 Thank you for your comment. No response necessary. COMMENT LETTER FROM U.S. ENVIRONMENTAL PROTECTION AGENCY January 7, 1980 Comment 1: We do have some questions even about the currently proposed fills. It is not clear whether the fills will have gentle slopes which will create some shallow water areas useful for fish habi- tat or whether vertical bulkheads are proposed to reduce con- struction turbidity. It would be useful to know how deep the water is and the total area of lake bottom which will be covered by these fills. Response 1: The slopes of any fill below water level would not exceed 12 horizontal to 1 vertical (refer to Comment 1 from Department of Fisheries) . The water is up to ten feet deep in areas of fill . The several small areas of fill would total approximately one acre. Comment 2: The effect of the various in-water structures on water circula- tion is not addressed. Adequate water circulation is necessary to maintain high water quality - a very desirable goal in such 95 8 Response 2: Due to recent modifications in the plans for the boat launch and the fact that all piers and wavebreaks would either be floating or pile-supported, no significant impact to water circulation will result. Comment 3: Every effort should be made to minimize turbidity problems in the lake. Response 3: Detailed descriptions of the measures used to control turbidity will not be available until final designs are completed. How- ever, clean, coarse material will be used for fills in the water. COMMENT LETTER FROM WASHINGTON STATE DEPARTMENT OF FISHERIES January 9, 1980 Comment 1: For those areas of fill in Lake Washington which will result in a permanent vertical waterward face greater than 1.5 feet below Ordinary High Water (OHW = 21.8 feet) we will request that the entire waterward face be sloped 1.5 feet horizontal to each 1.0 foot vertical to provide shallow water areas for juvenile sal- monid predator avoidance. Response 1: Thank you for this information. Comment 2: On page 22 it is stated that as a mitigating measure vertical or near vertical bulkheads could be built with fill material being placed behind them to reduce turbidity. Will these bulkheads be permanent or temporary? If permanent see the comment immedi- ately above. Response 2: The intention of the mitigating measure was installation of a permanent bulkhead for underwater fills; however, these will not be required since all underwater fill will be at a slope of 1.5 to 1 or less. Comment 3: Is the proposed fixed wavebreak near the boat launch ramp a floating structure on piles or will fill material be used? If fill material is used how will this affect surface water circu- lation or sediment deposition. Response 3: The entire fixed wavebreak and pier is either a floating struc- ture or supported by piles, thereby allowing water to circulate. Comment 4: Will any dredging be necessary, maintenance or otherwise? Response 4: A minimal amount of dredging associated with the proposed new boat launch will be necessary. Comment 5: Since juvenile salmon migration may be adversely affected by artificial lighting their use should be held to a minimum and not illuminate surface waters directly. 97 Response 1: A detention pond for stormwater runoff is proposed upstream of the marsh area. (Refer to page 51 of the Draft EIS. ) In addition, oil/water separators and silt traps will be installed in the catch basins for all the roads and parking lots within the project. (Please refer to Response 4 to the Environmental Pro- tection Agency and to page 27 of the Draft EIS.) Comment 2: We recommend you use native vegetation as much as possible. Increased use of native vegetation for landscaping would reduce the need for fertilizers and thereby reduce storm water pollu- tants entering the lake. Many types of native plants can be aesthetically pleasing and also benefit wildlife (for example, dogwood, snowberry, and so forth) . Response 2: The use of native vegetation wherever possible is part of the plan for the park expansion. (Please refer to page 29 of the Draft EIS.) Inclusion of food-producing species (e.g. , haw- thorne, dogwood, willow, snowberry, vine maple and wild rose) was stated as a mitigating measure on page 31. Along with reducing stormwater pollutants, maintenance costs and problems would be minimized by the planting of native vegetation (Refer to page 48 of the Draft EIS) . COMMENT LETTER FROM WASHINGTON STATE DEPARTMENT OF TRANSPORTATION December 19, 1979 No comment. No response necessary. COMMENT LETTER FROM WASHINGTON STATE OFFICE OF ARCHAEOLOGY AND HISTORIC PRESERVATION December 14, 1979 Comment: In the event that unknown archaeological resources are inadver- tently unearthed during construction activities, please notify the Office of Archaeology and Historic Preservation in Olympia, and the Washington Archaeological Research Center, Pullman, Washington. Response: If any archaeological resources are discovered during construc- tion, the office of Archaeology and Historic Preservation will be notified. COMMENT LETTER FROM WASHINGTON STATE PARKS AND RECREATION COMMISSION December 11, 1979 No comment. No response necessary. 99 The Gene Coulon Park Expansion proposal is located almost en- tirely within the designated shoreline of the City of Renton. Therefore, construction of boat ramps, bulkheads, piers and docks, parking, trails and filling and stream alteration must conform with the specific use regulations of the Master Program. Construction of the piers and docks may require a variance from these regulations, which must be approved by the State of Wash- ington. Response 1: The Shoreline Master Program and/or the need for a shoreline management Substantial Development Permit are referenced on pages ii and 18 of the Draft EIS. Representatives of the Department of Ecology, the Renton Plan- ning Department and the Parks Department and its consultants attended a meeting to resolve this question. It was agreed that no amendment to the City Shoreline Master Program, conditional use permit or variance to the shoreline regulations would be appropriate or necessary to allow the proposed development. A substantial development permit will be required under the Renton Shoreline Master Program. Comment 2: Portions of the park development, specifically the floating piers, docks and log booms, extend beyond the inner harbor line and out to the outer harbor line. The inner harbor line defines the City of Renton's corporate limits and the City' s jurisdic- tion does not extend beyond. In order to accomplish development of the park in this portion of Lake Washington, approval from the State of Washington may be required. This situation should be investigated and clarified in the Final EIS. Response 2: The area between the inner and outer harbor limit is controlled by the Port of Seattle on behalf of the Department of Natural Resources and portions of this are presently under lease to the City of Renton. Additional leases will be obtained from the Port for the entire length of the park. Comment 3: The discussion of air quality impacts from additional vehicular traffic generated by the proposal should be expanded. The re- duction in overall vehicle emissions predicted for 1982 and 1990 as a result 'of tighter Federal guidelines is emphasized in the Draft EIS. We feel it would be more appropriate to address the additional air quality impacts of the proposal that could be expected over and above the predicted future pollutant levels, whatever they may be. Response 3: The air quality impacts of the proposal will be less in 1990 than they are at present. The concentration of carbon monoxide is not predicted to exceed 1 ppm. Even after adding all the projected traffic, the 1990 concentrations will be about 80% lower than the existing levels. (Refer to letter from Puget Sound Air Pollution Control Agency. ) Comment 4: Regarding reduced conflicts between user groups that may result from park expansion, it is unclear whether this result is a goal of park development and design or not. The implications of potential separation which are noted as mitigating measures 101 COMMENT LETTER FROM RON NELSON - RENTON PUBLIC WORKS DEPARTMENT (BUILDING DIVISION) January 18, 1980 Comment: Would suggest work hours be established in order to minimize noise entering the residential areas. Response: A suggested mitigating measure on page 35 of the Draft EIS was to limit working hours to the period 8:00 AM to 6:00 PM in order to lessen the impact of construction noise on residential areas. COMMENT LETTER FROM LEONARD STEINER December 10, 1979 Comment 1: If the vegetation removal can be held to a minimum and all vegetation replanting of trees and shrubs were beneficial to wildlife, then a unique habitat could be created. Generally a good mix of evergreen and deciduous that produce berries and provide cover are the most beneficial . This could be accom- plished in some of the passive use areas. Response 1: Thank you for your comment. (Please refer to Response 2 to the Washington State Department of Game. ) Comment 2: If the log-boom was made three to four logs wide, then it could provide a resting area for the water fowl that use these envi- rons. Response 2: The suggestion for providing a resting area for waterfowl is an interesting one and will be considered for the final park design. Thank you for your recommendation. 103 I I MARS BEGINNING OF FILE FILE TITLF s PEG 1 A PE R P`I I T" 5 P - n�.5 - $� RENrON , CITY OF PARKS pEPAmrMENT r.,FN� COLIION MEI''�ORIfI L BEAGM _ PH�k OF R4,, �0 THE CITY OF RENTON MUNICIPAL BUILDING 200 MILL AVE.

APPLICANT: City of Renton FILE NO. SP-065-80 LOCATION: East side of Lake Washington between Puget Power Steam Plant and Coleman Point. SUMMARY OF REQUEST: The applicant is seeking approval of a special permit to allow regrading of the subject site in preparation for future expansion of an existing waterfront park. SUMMARY OF ACTION: Planning Department Recommendation: Approval with conditions Hearing Examiner Decision: Approval with conditions PLANNING DEPARTMENT The Planning Department preliminary report was received by the REPORT: Examiner on July 31 , 1980. PUBLIC HEARING: After reviewing the Planning Department report, examining available information on file with the application, and field checking the property and surrounding area, the Examiner conducted a public hearing on the subject as follows: The hearing was opened on August 5, 1980 at 10:00 a.m. in the Council Chambers of the Renton Municipal Building. Parties wishing to testify were affirmed by the Examiner. It was reported that the Hearing Examiner and the applicant had received and reviewed the Planning Department report. Steve Munson, Planning Department, reviewed the report, and entered the following exhibits into the record: Exhibit #1 : Application File containing Planning Department report and other pertinent documents Exhibit #2: Site Plan showing existing conditions Exhibit #3: Site Plan of proposed structures and improvements Exhibit #4: Grading and Drainage Control Plan The Examiner entered the following exhibit into the record by reference: Exhibit #5: Draft Environmenta' Impact Statement, 1979 Responding to the Examiner's inquiry regarding required shoreline permits, Roger Blaylock, Associate Planner, advised that a required Shoreline Management Permit has been prepared . for which the local review period expired on August 2, 1980. Subsequent to receipt of the Examiner's report containing conditions of approval , he indicated that the permit will be forwarded to the appropriate state agency. The Examiner requested testimony by the applicant. Responding was: John Webley Park Director City of Renton Mr. Webley indicated that the requested grading permit is part of a greater shoreline project, and ramifications of the grading project have been taken into consideration by the entire environmental community including the Musk Oxen Committee, a state and federal environmental review agency. He noted that all shoreage treatment has been reviewed by those agencies, and a great amount of time, effort and funds have been expended to assure protection of the environment and aquatic life, in particular. Referencing Section L.2 of the Planning Department report regarding timing of project phases, Mr. Webley advised that due to wet conditions during winter months, the timing of Phase I will be revised, and the project during that phase will include relocation of the existing stream and provision of a berm on a portion of the area within the existing park. He noted the city's intent to make every effort to reduce erosion and sedimentation problems incurred 0 SP-u65-80 Page Two as a result of inclement weather. During the Phase II portion of the project, Mr. Webley indicated that shoreage treatment and upland grading would be addressed further up the site, and the Engineering Division will be responsible for monitoring controls for dust, erosion and sedimentation in the project. The Examiner requested testimony in support or opposition to the application. There was no response. He then invited final comments from the Planning Department staff. Mr. Blaylock advised that detailed drainage control plans included in Exhibit #1 reflect the city's intent to create an interceptor along the lake to intercept water and install a sedimentation pond. In the last phase, he indicated that berming will be removed and the shoreline area will be provided with a rock wall , sand or gravel . Responding to the Examiner's request for an extended review period of 21 days to allow for staff absence, Mr. Webley indicated concurrence. He then inquired if submission of the Shoreline Management Permit to the state agency would be delayed. Mr. Blaylock advised that the permit would be forwarded as soon as possible. Since there were no further comments, the hearing regarding File No. SP-065-80 was closed by the Examiner at 10:15 a.m. FINDINGS, CONCLUSIONS & DECISION: Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1 . The request is for approval of a special permit to fill and grade portions of +53 acres of property, commonly known as the Coulon Beach Park Expansion, with approximately 70,000 cubic yards of fill . 2. The application file containing the application, SEPA documentation, the Planning Department report, and other pertinent documents was entered into the record as Exhibit #1 . 3. Pursuant to the City of Renton's Environmental Ordinance and the State Environmental Policy Act of 1971 , R.C.W. 43.21 .C. , as amended, an Environmental Impact Statement was prepared for the entire subject proposal including the grading and filling operation. 4. Plans for the proposal have been reviewed by all city departments affected by the impact of this development. 5. There was no opposition to the proposal expressed. 6. All existing utilities are available and in close proximity. 7. The subject property is located on the east side of Lake Washington between the Puget Power Steam Plant and Coleman Point. The property is owned by the City of Renton and is proposed for the expanded operation of the existing and developed Gene Coulon Beach Park. 8. The subject property slopes downward from east to west toward the shore of Lake Washington. The grades are between one and two percent. An existing stream on the property is proposed to be relocated by the applicant as part of the grade and fill operation. 9. The site is covered with a variety of shrubs, grasses and small trees incuding scotch broom, alder and cottonwoods. 10. A majority of the subject site is zoned H-1 (Heavy Industry) while the northernmost portion of the site is zoned G-6000 (General ; Single Family Residential ; Minimum lot size - 6,000 square feet) . Zoning in the area mirrors the zoning of the site with H-1 predominating to the south and G-6000 on the north and east. There is also T (Mobile Home Park) , B-1 (Business/Commercial) , and R-3 (Medium Density Multifamily) zoning east of the site. 11 . The Comprehensive Plan designates the area in which the subject site is located as suitable for the development of recreational uses. 12. The site itself is basically undeveloped. The Boeing Company complex is located south of the subject site. Single family residences are located east of the subject site, as is a mobile home park. • 13. The applicant proposes to fill the site in two phases which are somewhat dependent upon the weather. These plans differ from those indicated in the Planning Department report in that Phase I will include relocation of the existing stream from the proposed expansion site to the existing beach park, an0 berming and stabilization of the soils above the lake will occur to prevent erosion. Phase II would complete site SP-065-80 Page Three preparation and shoreline alterations. 14. These operations are scheduled for the fall of 1980 and the spring of 1981 (Phase I ) , and June of 1981 to June of the following year. A more detailed presentation of the grading and filling plans is presented in the EIS prepared for the project. Temporary landscaping and erosion prevention measures will be undertaken on the site during the various phases. 1 . After termination of the fill and grade operation, the site will be landscaped and developed as befits a lake shore recreational facility including docks, piers, picnic and recreational facilities, and comfort stations. 16. A drainage control plan has been submitted and the Engineering Division will monitor ongoing performance. 17. The site is just north of the large industrial area of the city, and the Police Department has recommended that hauling hours be limited so that truck traffic does not interfere with the afternoon peak traffic hours. 18. The various segments of the park expansion plans are subject to review by numerous state and federal agencies, and permits have been applied for as required by law. CONCLUSIONS: 1 . The EIS filed and published for the project discloses the various impacts associated with not only the fill and grade operation but the total expansion effort. The grade and fill is necessary to permit the development of an expanded recreational facility along Lake Washington. The fill and grade work performed will restructure the existing contours to allow public access and use and the development of recreational structures. 2. The work will be phased and generally carried on to limit interference with the remainder of the beach park. Further, the work is to be performed at a time and in a manner to minimize work during extremely wet periods and to avoid erosion and sedimentation problems on the shoreline and in the lake. 3. In order to avoid interference with the peak traffic hours of the industrial areas just south of the subject site, hauling of fill should be limited to the hours of 7:00 a.m. to 3:00 p.m. Further, so as not to impair the roadways themselves, debris generated by the hauling project should be cleared off the public streets at the end of each day or as conditions warrant. 4. The applicant has submitted plans for the temporary control of erosion and the containment of sedimentation. There will be temporary landscaping and sedimentation devices installed following Phase I . DECISION: The request to fill and grade the subject site is approved subject to: 1 . Limiting truck travel to between the hours of 7:00 a.m. and 3:00 p.m. 2. Clearing of debris from the public streets as conditions warrant, but no less frequently than daily. 3.

PLANNING DEPARTMENT PRELIMINARY REPORT TO THE HEARING EXAMINER PUBLIC HEARING : CITY OF RENTON, SP-065-80 AUGUST 5, 1980 PAGE TWO C . HISTORY/BACKGROUND: The subject site was annexed into the City of Renton on September 8, 1959 by Ordinance 1791 at which time the G-6000 zone was established. The H-1 zoning was approved by Ordinance 1884 of May 2 , 1961 . Parcels included in the subject site were purchased for public use in 1971 and 1979 . D. PHYSICAL BACKGROUND: 1 . Topography: The subject site slopes generally downward from east to west at a 1-2% grade. 2 . Soils : Alderwood gravelly sandy loam (AgC) . Permeability is moderately rapid in the surface layer and suboil and very slow in the substratum. Runoff is slow to moderate and the erosion hazard is moderate. This soil is used for timber, pasture, berries , row crops and for urban development . Alderwood Gravelly sandy loam, 15-30% slopes (AgD) . Runoff is slow to medium, the erosion hazard is severe. The slippage potential is moderate. This soil is used mostly for timber . Some areas on the lower parts of slopes are used for timber . Urban land (Ur ) is soil that has been modified by disturbance of the natural layers with fill material to accommodate large industrial and housing installations . The erosion hazard is slight to moderate. 3 . Vegetation : Scotch broom and scrub grass dominate the area as ground cover . A few alder and cottonwoods are interspersed among short to medium growth shrubs . 4. Wildlife : The existing vegetation provides suitable habitat for birds and small mammals . 5. Water : The subject site abuts Lake Washington on the westerly border. 6. Land Use : The subject site is basically undeveloped. To the south is the existing waterfront park and the Boeing Co . complex. Lake Washington is adjacent to the west and single family subdivisions and a mobile home park are to the east . E . NEIGHBORHOOD CHARACTERISTICS : The surrounding properties are a mixture of industrial , recreational and residential land uses . F . PUBLIC SERVICES : 1 . Water and Sewer: A 3" water main runs along the west side of Lake Washington Blvd. North from approximately North 26th Street to North 29th Street while a 6" main is located on the same side of the street from North 29th to North 33rd. The Metro Gravity sewer extends northerly to North 26th Street along the west side of the Blvd. and an 8" sanitary sewer runs by the east side from approximately North 20th Street northward. a PLANNING DEPARTMENT PRELIMINARY REPORT TO THE HEARING EXAMINER PUBLIC HEARING : CITY OF RENTON, SP-065-80 AUGUST 5, 1980 PAGE FOUR 4 . City of Renton Utilities Division . 5. City of Renton Fire Department . 6. City of Renton Parks Department . L . PLANNING DEPARTMENT ANALYSIS : 1 . The subject proposal is consistent with the existing zoning for the site and generally conforms to the Comprehensive Plan land use designation for the surrounding area . 2 . The applicant proposes to re-grade the subject site in the amount of approximately 70,000 cubic yards . Only limited quantities of specialized rock and gravel fill will be imported. This is to be accomplished in two phases. Phase I (or the rough grading phase) will involve considerable disturbance to the upland portion of the site . Filling here is designed to reduce on-site erosion and keep sediment from entering Lake Washington. Some temporary vegetation and sediment control devices will also be incorporated to reduce erosion. (Fall 1980 and April 1981 ) . Phase II (the finished grading phase) will focus on excavation, filling, and/or modifying the shore edge and bottom of the lake. Sediment and erosion control measures taken in Phase I will be maintained until the Phase II activities required their removal. (June 1981 to June 1982) . Detailed drainage plans will require Engineering Department approval . 3. Pursuant to the fill operation , expansion of the existing park is projected. This will include such facilities as fishing piers, boat ramps , an improved gravel beach, some rip-rap with wall and associated marina structure . 4. A description of proposed landscaping along with a site map have been included with the application. Treatment is to be composed of an informal or natural structure for the northerly port and more formal plantings consisting of trees , shrubs, and ground cover for the more southerly or developed portion. The submitted map is very conceptual in nature and specific details will need to be addressed in submission to the Planning Department for approval . 5 . The Police Department advises that the following measures be undertaken during construction : a . Work hours to be confined to the hours of 7:00 a .m. to 3 :00 p.m. for hauling. b. The hauling route to the subject site is to be reviewed and monitored by the Traffic Engineering and Police Department. c . Streets involved are to be kept clean of debris. d . Truck routes are to be posted with appropriate signing as determined by Traffic Engineering. M. DEPARTMENTAL RECOMMENDATION: Based upon the above analysis, recommend approval of the special permit request subject to the conditions noted in L-2 , L-4 and L-5. 1 REVIEWING DEPARTMENT/DIV' ` ION : - Approved X Approved with Conditions Not Approved ^ed-4 ":..,,Q rawliff2- cam.-,_ 1 4 4...,..k._ is...___ zkYteo Signature of Director or Author ze Repre en ative Date REVIEWING DEPARTMENT/DIVISION: Deittfoiefc 0 0 50$0 O,v.

Specifically the plan ' s objective is to limit as much as possible accelerated erosion and sedimentation and to control dust levels while the park is being built. The above objective will be met largely through the imposition of controls on construction activity. These controls shall include the general conduct and timing of the contractor's activitites on the site and the use of specific erosion, sedi- mentation, and dust protection devices and practices. EXISTING GRADING AND DRAINAGE The site of the Gene Coulon Memorial Park extension is basically a flat industrial fill area with a gentle slope from its eastern boundary toward Lake Washington on the west (See Site Plan: Existing Conditions) . Upsiope runoff enters the site through a number of culverts that pass beneath the Burlington Northern Railroad tracks paralleling this eastern boundary. From there, this off-site runoff enters small drainage channels or cor- rugated metal pipe and is directed through the site into Lake Washington. On-site runoff generally reaches Lake Washington through the small drainage channels or by sheet flow. The one exception to this drainage pattern is the only signifi- cant "stream" on the site. This stream (actually a man-made channel) flows along the site ' s southern boundary into Lake Washington. It collects some runoff in the southernmost end of the site but most of its flow is from off-site drainage. In contrast to the flat topography of the site is the Lake Washington shoreline. The lake edge is generally abrupt consisting mostly of steep banks or pile bulkheads. The banks show signs of erosion and collapse as a result of lake wave action. 'JUL 2i \ n rty GRADING AND DRAINAGE ACTIVITIES Contract I Under the first construction contract, grading work will be centered around the stream area that forms the boundary between the existing Gene Coulon Memorial Beach Park and the park " extension area to the north. (See Site Plan: Existing Condi- tions) . The purpose of this contract is to make those changes in the existing park that will be necessary for it to "fit" with the proposed park features . The major grading activity during Contract I will be to relocate the existing stream channel in order to accomodate new park structures and to relocate some of the parking areas. (See Pro- posed Grading and Diainage Control. Plant) , The stream relocation will proceed in several stages - to minimize erosion and sedimen- tation of the stream and the lake. First, the new stream channel will be excavated except for earth plugs at its upstream and downstream ends. When all grading, stabilization, and planting of the new channel is completed, the downstream plug will be removed and the new stream mouth will be established. The formation of the new stream mouth will involve placing fill in the lake. The fill will be clean material as required by the Department of Fisheries to lessen turbidity. After the mouth area is stablized, the upstream plug will be re- moved and the water from the existing stream will be diverted into the new channel. Until the existing stream is success- fully diverted, its channel and the adjacent bank vegetation will be left undisturbed. This will minimize erosion of the stream bank and resultant sedimentation of the stream and lake while the diversion process is underway. In addition, temp- orary diversion channels and sediment basins will be utilized to keep sediment from upland runoff out of these water bodies. All graded areas south of the relocated stream will then either be paved or permanently landscaped. This area will essentially be completed before heavy public use of the park resumes in 1981. Areas immediately north of the relocated stream consisting mostly of existing paved parking will be left intact. They will be rehabilitated with new striping and access points so the existing boat ramp can be used in the interim. Contract II In this contract all remaining grading work in the new park would be carried through to final elevations. Included would be all 2 shoreline modifications and upland grading. The timing for the commencement of shoreline and in-lake construction activity depends on the outcome of a waiver being sought from the Washington State Department of Fisheries to begin work in Lake Washington prior to June 15, 1981 . From a construction point of view, the earlier in the year that shoreline earthwork could begin, the better. Lake Washing- ton' s water level is about a foot lower in the winter and early spring permitting the contractor better shoreline access. Shoreline work would proceed as rapidly as possible to reduce the length of time the shore edge would be disturbed. Material excavated along the shore edge would be used throughout the upland portion of the site as fill. New fill placed in contact with the water would be relatively clean material. (For a detailed picture of the proposed shoreline modifications refer to the . Site Plan: Proposed Structures and Shore Conditions and to the detailed shoreline sections in Appendix A) . The commencement of upland grading is dependent upon upland soil conditions rather than fisheries considerations. The soil has to be sufficiently dry to achieve proper compaction. Grading the upland area in drier conditions also reduces erosion potential. In the upland part of the park, existing off-site drainage will continue to be directed beneath the northern part of the site through existing or upgraded drain pipe. (See Proposed Grading and Drainage Plan) . In the middle section of the site, a perforated pipe subdrain will be installed to intercept off- site runoff and groudwater in that area. This water will be directed into a new storm sewer with its outfall in Lake Washing- ton. Because no off-site drainage will pass over the surface of any disturbed areas treatment for sedimentation will not be necessary. On-site runoff, however, will pass over upland graded areas . It will be picked up in a swale system. A lake edge interceptor channel (See Proposed Grading and Drainage Plan) will gather the runoff from these upland swales and direct it into sediment basins established along the lake shoreline. All on-site runoff from upland areas will therefore have to pass through a sediment basin before it can enter Lake Washington. As upland grading nears completion, a storm sewer system will be installed in the southern portion of the site. On-site run- off formerly directed into the lake edge interception channel will be redirected into the new storm sewers. The catch basins will be left elevated and protected by filtering devices 3 to catch sediment until adjacent areas are paved and permanently planted. In the middle and northern sections of the site, the interceptor channel and sediment basins will be removed once well-vegetated drainage swales are permanently established. Approximately 70, 000 cubic yards of excavation and fill will take place during the grading of the park. Fill material will be produced primarily through grading the future parking area just north of the existing stream and the regrading of the pre- sent abrupt shoreline into gentler slopes . Excess material from the shoreline excavations will be used for mounding on the existing flat upland area. Some of the existing dredge material '. stockpiled at the north end of the site will be used for fill throughout the park. The only fill materials that will have to imported to the site are: rip rap and clean fill material for use along the lake edge; base course material for roads , parking lots, and other hardsurfaced areas ; and soil ammendments to improve the existing soil' s fertility. CONTROLLING EROSION, SEDIMENTATION AND DUST Construction Specifications The control of potentially adverse effects of construction activity with regard to erosion, sedimentation and dust will be accomplished through enforcement of special provisions to the construction contract specifications. In the specifica- tions, the contractor will be required to adopt the Erosion and Sedimentation Control and Dust Control Measures outlined below, or submit acceptable plans of his own. Should unfore- seen conditions arise, the project engineer will direct the contractor to take additional measures to those herein described. Erosion and Sedimentation Measures These measures consist of specific control devices and practices that will be utilized on site. They are described in the following paragraphs and are illustrated in Figures 1 and 2. In addition, the 1" = 100' Proposed Grading and Drainage Control Plan has been provided to indicate the general location of these measures throughout the site during construction. Temporary Vegetative Cover will be used on all portions of the site where soils will be exposed for more than 60 days. Seed mix, fertilizer and method of application will be applied as required to adequately stabilize the soil. 4 Permanent Vegetation will be installed as soon as possible after final grades have been achieved. The establishment of a per- manent ground cover will provide an excellent means of protect- ing the park and lake from future erosion and sedimentation. The planting design and plant materials to be used in the park are shown on the Landscape Plan. An accompanying descriptive text can be found in Appendix B. Soil Stockpiling and Rough Grading will not be at grades steeper than 3 : 1 for slope stability and ease of seeding and mulching with conventional machinery. Elevated Drain Inlets and Inlet Filter Protection will be provided for all storm sewer inlets ' installed prior -to final grading .(See Figure 1) . Inlets will be left elevated a minimum of 10 inches above the surrounding grade for a radius of 15' . This will temporarily pond most of the runoff and allow sediment to settle out. A filter of hay bales, gravel, or filter fabric will be used to surround the inlet and screen out sediment as well. Sedimentation Basins with overflow control structures shall be used to collect all runoff that is not directed into the storm sewer system (See Figure 2) . All runoff will either enter the protected storm sewer inlets or pass through a sedimentation basin before entering Lake Washington. Lake Edge Interceptor Channels and Diversions shall be provided above the shoreline of Lake Washington to intercept runoff and direct it into sedimentation basins. Check dams along the interceptor channels may be used to slow runoff before reaching the sedimentation basins. Maintenance of Erosion and Sedimentation Control Measures The contractor will be responsible for all maintenance of erosion and sedimentation control measures. The construction contract specifications will require inspection of all erosion and control devices for proper operation on a regular basis as well as after heavy rainstorms. Areas that are found to have undergone rill erosion, gullying, or other serious erosion processes will be immediately regraded, stabilized, and replanted. Any erosion control devices that have been damaged will also be repaired or replaced. 5 Accumulated sediment in sediment basins and ponding areas will be removed whenever the sediment exceeds 50% of the holding capacity of the catchment. Sediment accumulated around inlet filters or in channels will also be removed whenever it inhibits the proper functioning of these control devices . Dust Control Measures The contractor will be responsible for controlling the dust levels during construction as much as possible. Ideally, the dust should be confined to the site. When dry conditions prevail a water wagon should be used to keep dust levels down. If dust conditions become especially bad, construction roads may have to be covered with mulch and/or stone and then watered. Temporary vegetation cover required on all exposed soils (over 30 days) will help reduce dust levels as well. Vehicles will have excess mud and dirt removed before leaving the site. • 1 1;51(zADILJ kin. 1500412 FlrlISNw Gz,A.n 44 P0.4LPS � /1 s yi 1 � ,,� 1 1 1 1 i �C', 1 1 1 . 1 , i, N.

Ericksen jy I City of Renton S . �j .. / Municipal Bldg. _.,, 200 Mill Ave. South - Renton, Wa. 98055 Dear Mr. Ericksen: The enclosed is a revision to the original Special Permit Submission under cover letter dated 8 July for Filling and Grading in the Gene Coulon Memorial Beach Park Extension, City of Renton. The following two parts of the original submission are superceded by these enclosures: Grading and Drainage Control Plan (text ) Proposed Grading and Drainage ( drawing) Appendices A and B of the original Grading and Drainage Control Plan ( text ) and all other supporting data are not affected by the revision and remain part of the permit submission. Changes to the original Grading and Drainage Control Plan are a consequence of rescheduling construction activity on the park. In the previous Grading and Drainage Control Plan, grading was to be carried out over the entire park site in two distinct time frames: Phase I Rough Grading - Fall 1980 and Spring 1981 Phase II Finished Grading - June 1981 to June 1982 with shore edge modification and pier con- struction in the period between June 15, 1981 and November 1, 1981. In the Revised Grading and Drainage Control Plan, the separation of the grading into rough and finished phases has been eliminated. Instead, only a small part of the park at the southern end of the site will undergo construction during the fall of 1980 and spring of 1981. Moreover, this part of the facility will be brought to completion during this time period. Grading and other construction activity in the much larger part of the park will begin in 1981 under additional contracts. -2- The precise timing for commencement of grading and construction in the remainder of the park has not been firmly established. A request has been made to the Washington State Department of Fisheries to waive their requirement that Lake Washington shore edge modifications and in-lake construction activity occur between June 15 and November 1. Should the waiver be granted, work in and along the lake could begin earlier than June 15, 1981, perhaps as early as February. Upland grading, on the other hand, could begin whenever soil conditions permit. One distinct advantage of working with a Department of Fisheries waiver would be to reduce the length of time that the major portion of the site would be exposed to erosional processes. Instead of having two large and separate grading phases there would be one minor grading phase and one major grading phase. Another advantage of working with a waiver would be to gain better control over the contractors activities. Under the previous construction schedule, the timing and coordination of Phase II was entirely dependent on the work schedule in Phase I. I trust these changes will have been received in time to be considered in your staff report to the Hearing Examiner. Sincerely yours, C /A-4- 04ft Robert F. Hintz RFH/mh cc: David Towne Philip A.

This first submission, the Grading and Drainage Control Plan and supporting data, is to be reviewed by various City of Renton departmental offices and then incorporated in a city staff report to the Public Hearing Examiner. In addition, copies of this Grading and Drainage Control Plan will be sent to appropriate state agencies so that their comments might also be incorporated into the city staff report. The second Special Permit submission, to be submitted at a later date, consists of technical data primarily in the form of grading construction drawings. This technical submission will be re- viewed by the City of Renton engineering staff and incorporated in their departmental report to the Public Hearing Examinier. The Hearing Examiner will evaluate the Special Permit applica- tion and the city and state agency comments . He will also hold a public meeting for open discussion on the proposal. Based on this input, he may either recommend for or against approval of the permit, impose added conditions for permit approval, or ask for more information on the proposal. GRADING AND DRAINAGE CONTROL PLAN OBJECTIVES AND DESCRIPTION. The purpose of this Grading and Drainage Control Plan is to protect those areas in the vicinity of the Gene Coulon Memorial Park extension from the possible detrimental effects associ- ated with construction activity. Specifically the plan ' s objective is to limit as much as possible accelerated erosion and sedimentation and to control dust levels while the park is being built. The above objective will be met largely through the imposition of controls on construction activity. These controls shall include the general conduct and timing of the contractor 's activities on the site and the use of specific erosion, sedi- mentation, and dust protection devices and practices . Because grading operations will proceed in two phases, over two distinct time periods, there will ,be of necessity a dif- ference in the control measures to be utilized. Phase I , the rough grading phase, will involve a great deal of disturbance to the upland portion of the site. Because most of the exist- ing upland vegetation will be stripped away at this time, much of the plan will be focused on reducing on-site erosion and keeping sediment from entering Lake Washington or the existing stream. Temporary vegetation establishment and the use of sediment control devices will be the major control measures for Phase I and that period of time until Phase II is well under way. During Phase II , the finished grading phase, a great deal of the work will focus on excavation, filling or otherwise modify ing the shore edge and bottom of Lake Washington. The level of disturbance will be controlled as much as is practical through careful scheduling of shoreline activity. The work along the lake edge will take place at a time of the year recommended by the Washington Department of Fish and Game to reduce the impact on lake and stream species . Sedimentation and erosion control measures established in Phase I will be maintained continually until Phase II activities necessitate their removal. At the end of Phase II all grading will be completed and permanent vegetation will be installed. The vegetation will be properly mulched and otherwise protected to prevent erosion until it is fully established. 1 EXISTING GRADING AND DRAINAGE The site of the Gene Coulon Memorial Park extension is basically a flat industrial fill area with a gentle slope from its eastern boundary toward Lake Washington on the west (See Site Plan: Existing Conditions) . Upslope runoff enters the site through a number of culverts that pass beneath the Burlington Northern Railroad tracks paralleling this eastern boundary. From there, this off-site runoff enters small drainage channels or cor- rugated metal pipe and is directed through the site into Lake Washington. On-site runoff generally reaches Lake Washington through the small drainage channels . The one.exception to this drainage pattern is the only signifi- cant "stream" on the site. This stream (actually a man-made channel) flows along the site' s southern boundary into Lake Washington. It collects some runoff in the southernmost end of the site but most of its flow is from off-site drainage. In contrast to the flat topography of the site is the Lake Washington shoreline. The lake edge is generally abrupt consisting mostly of steep banks or pile bulkheads . The banks show signs of erosion and collapse as a result of lake wave action. GRADING AND DRAINAGE ACTIVITIES Phase I Grading activity will proceed on the Gene Coulon Memorial Park extension in two phases , under separate contracts. Phase I grading, which will take place during the fall of 1980 and spring of 1981, will consist of rough grading of the upland part of the site above existing ordinary high water (except during stream relocation. see discussion below) . Except for the area along the shoreline of Lake Washington, the drainage pattern of the completed park will essentially be established by the end of Phase I by re-contouring existing on-site materials. During Phase I, off-site drainage will continue to be directed beneath the northern part of the site through existing drain pipes. (See Proposed Grading & Drainage Plan) . In the middle section of the site, along the park ' s eastern boundary, a perforated pipe subdrain will be installed to intercept off- site runoff and groundwater. This water will be directed into a new storm sewer with its outfall in Lake Washington. No on-site runoff will be permitted to enter this new storm sewer during this phase. 2 On-site runoff throughout the park will be picked up in a swale system. A lake edge interceptor channel (See Figure 3) will gather runoff from the upland swales and direct it into sediment basins established along the shoreline. Therefore, all on-site runoff during Phase I (and during much of Phase II have to pass through a sediment basin before it can enter Lake Washington. The existing stream channel along the southern boundary of the site will also be relocated during Phase I to accomodate new park structures and relocate the parking area. First, a new stream channel will be excavated except for earth plugs left at both the upstream and downstream ends. When all interior grading and stabilization of the new channel is complete, the downstream plug will be removed and the new stream mouth area will be stabilized. The upstream plug will then be removed and the water from the existing stream will be diverted into the new channel. Once the new stream is successfully established, the old channel will be completely backfilled. Until the existing stream is successfully directed, its channel and the vegetation adjacent to its bank will be left undisturbed. This will minimize erosion of the stream banks and resultant sedimentation of stream and lake water during the diversion process . Phase II Phase II, the final grading and construction phase, will take place from June 1981 to June 1982. All shore edge modifications and construction of pier structures, however, will take place during the period between June 15, 1981 and November 1, 1981. This latter period is one recommended by the Washington Department of Fish and Game for working in and along the shore of Lake Washington. During the shoreline modifications any material removed from the lake edge and bottom will be used throughout the site as fill. (For a detailed picture of the proposed shoreline modifications refer to the Site Plan: Proposed Structures and Shore Conditions and to the detailed shoreline sections in Appendix A) . During Phase II, the remainder of the storm sewer system shall be installed. As shoreline work necessitates the removal of the lake edge interceptor channel, on-site runoff will be directed into other sediment basins or the new storm sewers . The catch basins will be left elevated and protected by filter- ing devices to catch sediment until the adjacent surfaces are stabilized. In the northern part of the park, off-site drainage will con- tinue to be carried beneath the site in existing or upgraded culverts. On_- site drainage will be directed through the sediment basins installed in Phase I until well vegetated swales can be permanently established. 3 Approximately 70, 000 cubic yards of excavation and fill will take place during the grading phases of the park. Fill material will be produced primarily through using on-site dredge stock piles and from regrading the present abrupt shoreline into gentler slopes. Excess material from the shoreline excavations will be used for mounding on the existing flat upland area. The only fill materials that will have to be imported to the site are: rip rap and washed gravel for use along the lake edge; base course material for roads , parking lots , and other hard surfaced areas; and soil ammendments to improve the existing soil' s fertility. CONTROLLING EROSION', SEDIMENTATION AND DUST Construction Specifications The control of potentially adverse effects of construction activity with regard to erosion, sedimentation and dust will be accomplished through enforcement of special provisions to the construction contract specifications. In the specifica- tions, the contractor will be required to adopt the Erosion and Sedimentation Control and Dust Control Measures outlined below, or submit acceptable plans of his own. Should unfore- seen conditions arise, the project engineer will direct the contractor to take additional measures to those herein described. . • Erosion and Sedimentation Measures These measures consist of specific control devices and practices that will be utilized on site. They are described in the following paragraphs and are illustrated in Figures 1 through 3 . In addition, the 1" = 100 ' Proposed Grading and Drainage plan has been provided to indicate the general location of these measures throughout the site during construction. Temporary Vegetative Cover will be used on all portions of the site where soils will be exposed for more than 30 days. Seed mix, fertilizer and method of application will be applied as required to adequately stabilize the soil. Permanent Vegetation will be carried out primarily in Phase II although some existing plant material will be transplanted in Phase I. The establishment of permanent ground cover following finished grading will provide an excellent means of protecting the park and lake from future erosion and sedimentation. - 4 The planting design and the plant materials to be used in the park are shown on the Landscape Plan. An accompanying descriptive text can be found in Appendix B. Soil Stockpiling and Rough Grading will not be at grades steeper than 3 : 1 for slope stability and ease of seeding and mulching with conventional machinery. Elevated Drain Inlets and Inlet Filter Protection will be pro- vided for all storm sewer inlets prior to final grading (See Figure 1). Inletswill be left elevated a minimum of 10 inches above the surrounding grade for a radius_ of 15 ' . This will temporarily pond most of the runoff and allow sediment to settle out. A filter of hay bales , gravel, or filter fabric will be used to surround the inlet and screen out sediment as well. Sedimentation Basins with overflow control structures shall be used to collect all runoff that is not directed into the storm sewer system (See Figure 2) . All runoff will either enter the protected storm sewer inlets or pass through a sedimentation basin before entering Lake Washington. Lake Edge Interceptor Channels and Diversions shall be provided above the shoreline of Lake Washington to intercept runoff and direct it into sedimentation' basins (See Figure 3) . Check dams along the interceptor channels may be used to slow runoff before reaching the sedimentation basins. Maintenance of Erosion and Sedimentation Control Measures The contractor will be responsible for all maintenance of erosion and sedimentation control measures . The construction contract specifications will require inspection of all erosion and control devices for proper operation on a regular basis as well as after heavy rainstorms . Areas that are found to have undergone rill erosion, gullying, or other serious erosion processes will be immediately regraded, stabilized, and replanted. Any erosion control devices that have been damaged will also be repaired or replaced. 5 Accumulated sediment in sediment basins and ponding areas will be removed whenever the sediment exceeds 50% of the holding capacity of the catchment. Sediment accumulated around inlet filters or in channels will also be removed whenever it inhibits the proper functioning of these control devices. Maintenance on the Phase I erosion and sedimentation control measures will be the reponsibilitY of the Phase I contractor until work on the Phase II contract is begun. Thereafter, maintenance of these measures and any additional control measures installed in Phase II will be the responsibility of the Phase II contractor. Dust Control Measures The contractor shall be responsible for controlling the dust levels during construction as much as possible. Ideally, the dust should be confined to the site. When dry conditions prevail a water wagon should be used to keep dust levels down. If dust conditions become especially bad, construction roads may have to be covered with mulch and/or stone and then watered. Temporary vegetation cover required on all exposed soils (over 30 days) will help reduce dust levels as well. Vehicles will have excess mud and dirt removed before leaving the site. 6 1 iIIUS I 50lJt41 PINIIsNEa G� I*n� P i I j � 1 ;:„-„ �I 1 1 � � I 11 1 1 I _ 1 1 ' 1 I I I 1 , 1 1 I , I I •1� \ 1 1 I, ` 1 1 1In 1 1 __ 1 I '12j -, 1 1 t. l T / 1 � 1 5 { 1 i I It�II.�T ; Io'' Mlle• FOtZ15' � � �l RADIU� eAMP4T „ G S (TIol l _.__ ___ ......_ ___.„,. .,, ,..

APPLICATION BY: Renton Parks • - and Recreation Dept. DATE: SHEET g5 OF APPENDIX B ACCOMPANYING TEXT FOR GENE COULON MEMORIAL BEACH PARK LANDSCAPE PLAN Virtually the entire Gene Coulon Memorial Beach Park extension-- save for those areas given over to roads , paths , parking, beaches, or park structures--will be heavily planted with a combination of lawn grasses , trees , shrubs and ground cover. The character of the planting generally will be more formal in the southern portion of the site and more informal or natural appearing in the north. As indicated in Table 1, these two distinct characters will be achieved through the selection of the type of plant material used as well as the way this material is arranged on the site. Planting in the south part of the park--designed to be more intensively used than the north--will include a mixture of hardwood and coniferous trees , including oak, beech, redwood and fir. A wide variety of flowering shrubs , such as viburnum, spirea, rhododendron and azalea, will also be featured in this portion of the park. Lawn areas will be planted with a turfgrass mix and will be regularly mowed and maintained. Groundcovers such as St. John' s Wort and Periwinkle will be substituted for grass where appropriate (especially on steep slopes or where foot traffic is neither expected nor desired) . In the less intensively used north part of the site emphasis will be placed on the use of native and more informal trees page 2 and shrubs such as Oregon Maple, Douglas Fir, Red Osier, Dogwood and Serviceberry. Trees will be organized in looser groupings or clumps. Lawn areas in the north will be planted with a mixture of fieldgrasses and wildflowers; they will be mowed less frequently (perhaps 2-3 times each growing season) to allow them to take on a more natural appearance. Special planting areas proposed for the Park include the Activity Center, the stream, and several marsh areas in the north. The Activity Center, expected to be the most in- tensively used part of the park, will have the most formally structured plantings. For example, beech or yellowwood of 6" caliper will be arranged in a bosque along the main promenade and play areas . The stream area will contain more native plantings than used elsewhere in the south part of the site, including cattails and other streambank species. Similarly the two marsh areas (to be created behind the exis- ting railroad trestle and the proposed "marshview walk") will be heavily planted with cattails and similar semi- aquatic plants. The southern portion of the site will be serviced by a fully automated irrigation system. The north will be serviced by a main water line equipped with quick couplers to facilitate the attachment of equipment for manual watering as needed. page 3 The water lines will be sized to permit the installation of an automated system in the future if desired. Throughout the park, emphasis will be placed on the selec- tion of slower-growing, more permanent species and varieties of plants. This will provide greater long-term benefit from the plantings as well as requiring less maintenance than is usually associated with quicker-growing, shorter-lived species. Where appropriate, existing specimen black cotton- woods, Douglas Fir and other faster growing trees will be retained on the site as an integral part of the planting scheme.
