This report was prepared based on guidelines from the Department of Ecology (1994). PROJECT SITE The Welman Subdivision is a 3.5-acre site located on the hill southeast of Renton at 18417 ll 61h Avenue SE in King County, Washington (Figure 1 ). The King County parcel number is 3223059033. The eastern edge of the property is on 1161h Avenue SE. The topography on the site slopes down to a wetland swale, Wetland A, located on the north of the property, which drains to the west off the property. The majority of the property is mown grass fields. On the northern half of the property there is a mixed stand of big-leaf maple and Douglas fir. The property has a house in the center with landscaping. Wetland A is a 2,316 square foot, Category 4 wetland. Category 4 wetlands are typically afforded a 50-foot buffer. A 25-foot wetland buffer is acceptable with appropriate mitigation (King County Code, KCC, 21A.24.325(A)(3)(a). PROJECT DESCRIPTION Preliminary design of the project plans for subdividing the property into 26 lots. The plan includes widening 1841 h Street along the north edge of the property to connect to 116th Ave SE on the east edge of the property. A cul-de-sac will extend south from the access road into the center of the property. The King County Department of Transportation required the road for the cul-de-sac to line up with the access road to the development to the north and across 1841h Street. This avoids direct access to I 16th Ave SE. The cul-de sac crosses the middle of Wetland A. The subdivision plan includes a detention pond for the portion of Wetland A east of the road. KCC 21A.24.335(C) allows alterations to wetlands under 2,500 square feet with appropriate mitigation. EXISTING CONDITIONS WETLANDS One wetland, Wetland A is located in the north and northwest areas of the property. (Figure 2 and Table 1, Headwaters 2006). Wetland A forms a swale and drains to the west off the property. Most, 2,002 square feet of the wetland are located on site. The wetland extends off site, 314 square feet, where it drains into a stormwater system. The wetland receives water from precipitation and runoff.

Wetland categories and buffers. l~~1!:!F1ttqJW?Aii'7***i5!r8W1!ffi • May be reduced by 25 feet with appropriate mitigation WETLAND FUNCTIONS Wetlands have many functions that have a value to society. Wetland functions are generally considered as the "physical, chemical, and biological processes or attributes of a wetland without regard to their importance to society" (Adamos et al. 1987). Typically, both functions and values are evaluated in a wetland assessment. An assessment was made as to the effectiveness of these functions and values based only on direct observation (see Appendix B). Wetland Functions were evaluated using the Washington State Wetland Rating System for Western Washington (Ecology, 2004)(Table 2). This rating system awards points based on both the potential and on the opportunity the wetland has to provide the function. Functions assessed are in three broad functional areas: water quality, hydro logic and habitat functions. The points are determined for each of the functional areas, and then the points from all the functional areas are summed together to determine a functionally based rating for the wetland. Wetlands that score under 30 points are Category 4 wetlands due to their low functional quality. Wetland A is a slope class wetland based on the rating system, and was evaluated using the slope class rating form. Water Quality Hydrologic Habitat Total 32 32 36 100 10 2 5 17 Based on the functional assessment, Wetland A has minimal habitat or hydrologic functions and only limited water quality functions. Wetland A received a rating of 10 for Water Quality because of the wetland's slope, it's dense ungrazed vegetation and its proximity to residential pollution sources. For Hydrologic functions Wetland A received a 2 because its vegetation is not ridged, the few small depressional areas that could retain water in the wetland, and the down stream drainage is not known to have significant Welman Subdivision Wetland Mitigation Report 6 Headwaters October 28. 2005 flooding or erosion problems. Wetland A received a habitat rating of5 because of the lack of diversity in wetland vegetation structure, its seasonally inundated and saturated, it has between 5 to 19 plant species and there are no special habitat features in the wetland. However, it is more that 85 feet from buildings or paved areas, and the Soos Creek park and wetland complex is within three miles. The total score of 17 for Wetland A represents it overall low functional quality, and thus is rated as a Category 4 wetland. BUFFERS Mown grasses dominate the buffer around Wetland A and a mixed stand of big leaf maple and Douglas fir provide a overstory in the north central portion of the property. The previous property owned has removed some of the lower branches of the big-leaf maple and Douglas fir. These areas provide limited buffer functions. The buffers provide moderate to no screening of the wetland from human activity. The low vegetative structure and lack of plant diversity provide only limited wildlife habitat. The tall trees do provide good habitat for passerine birds and raptors. PROJECT IMPACTS WETLAND FILL The project will fill and grade 1,122 square feet of Wetland A for the road and detention pond (Figure 3). Wetland A is a Category IV wetland, 2,316 square feet in size, and dominated by grasses. The wetland provides almost no habitat or hydrologic functions and some water quality functions. BUFFER LOSS Category IV wetland buffers are 50 feet. These buffers may be reduced per KCC 21A.24.325(A)(3)(a) by 25 feet with appropriate mitigation. These mitigation measures are planned for implementation; so buffer losses as well as gains are based on the 25-foot buffer. Total buffer loss equals 7,690 square feet (Figure 3). These buffers are primarily grass with some large big-leaf maple and Douglas fir. The buffers provide some water quality functions and limited wildlife habitat functions. Welman Subdivision Wetland Mitigation Report 7 Headwaters October 28. 2005 CONCEPTUAL MITIGATION PLAN The conceptual mitigation is composed of four major goals that together will mitigate for the loss of 1,122 square feet of wetland, loss of7,690 square feet ofbuffer and the reduction of the buffer width by 25 feet (Figure 4). The mitigation plan goals are listed below. • Create 1,256 square feet of forested wetland • Enhance 885 square feet of wetland by converting it to forested wetland. • Enhance the existing buffer • Add and enhance 8,742 square feet of wetland buffer. MITIGATION RATIOS Standard mitigation ratios for a Category IV wetland are 1.5 to I --creation area to impacted area (KCC 21A.24.340 B2). This project will impact 1,122 square feet of Category IV wetlands and therefore needs to provide 1,683 square feet of mitigation credit to meet the standard mitigation ratio. Standard mitigation ratios for buffers are one to one (Table 3). This project will impact 7,690 square feet of buffer and will need to provide a similar area of buffer to mitigate these impacts. Dreamcraft Homes proposes to replace the impacted wetland area plus pro vide additional enhancement to meet the standard mitigation requirements. To determine the amount of creation and enhancement necessary, it is helpful to consider creation and enhancement as providing credits. Creation provides an area credit equal to the area created. Enhancement receives less credit since it is an improvement on what already exists. Enhancement typically has received half credit (Ecology 1998) and most recently has been recommended to receive a one-quarter credit (Ecology 2005). In this case, we are proposing to convert a grass dominated wetland into a forested wetland, which likely dominated the site historically. This type of enhancement is closer to rehabilitation, which receives half credit. Plus as opposed to most enhancement projects, changing a grass dominated wetland to a forested wetland will improve all wetland functions substantially. Therefore, enhancement from low quality grass swale to higher quality forested wetland was considered to provide half the credit of wetland creation. Welman Subdivision Wetland Mitigation Report 9 Headwaters October 28. 2005 For this project, wetland creation provides 1,256 square feet of credit. Wetland enhancement of 885 square feet of wetland provides another 442 feet of mitigation credit. Combining the 1,256 square feet of wetland creation credit with the 442 square feet of enhancement credit provides a total of 1,698 square feet of wetland mitigation credit,just above the 1,683 square feet needed. Dreamcraft proposes adding 8,472 square feet of buffer to replace the 7,690 square feet of buffer impacted. Table 4. Credits provided for m1t1gat1on Critical Miti ation Area Credit Total Credits Area Type (sf\ Ratio Provided (sf\ (sf\ Wetland Creation 1,256 ]:] 1,256 1,698 Enhancement 885 1:0.5 442 Buffer Creation 8,472 ]:] 8,472 8,472 RATIONALE The proposed mitigation design will create wetland that improves the habitat, hydrologic and water quality functions over the wetland area impacted and similarly enhance the remaining wetland. The mitigation design will enhance and relocate the buffers improving the functions they provide. The proposed mitigation design will widen the wetland area by excavating areas north and south of the existing wetland. Two small rock and dirt weirs will help retain water in the wetland and create an area of seasonal ponding. In addition, the weir will provide a mechanism that will allow for adjusl!nent of the water level in the wetland if necessary to assure wetland hydrology in the created wetland area. The increased duration of ponding will provide a seasonal source of water for wildlife and improve water quality and hydro logic functions of the wetland. The proposed mitigation design creates a forested wetland with a patch of emergent plants surrounded by ring of shrubs. Conifers, prior to settlement by Europeans, dominated most forested wetlands in Western Washington. Conifer forested wetlands are no longer very common in Western Washington (Sargent and Salminen 1996). Planting conifers could improve the successional rate at which this forested wetland returns to its probable climax community and re-create a conifer-forested wetland that is uncommon in this region. The conifers would also provide more screening and winter cover for wildlife. By planting conifers, we will favor a more rapid return to the probable climax community of the wetland before logging of the site. The small patch of emergent and scrub-shrub habitat will add to the vegetative and structural diversity of the site. Welman Subdivision Headwaters Wetland Mitigation Report 11 October 28. 2005 The mitigation design reduces the buffer by 25 feet, from 50 feet to 25 feet, through enhancement. According to King County Code (21A.24.325(A)(3)(a)), this is acceptable with 1) fencing or landscape to discourage disturbance by humans and pets, 2) removal of non-native plants, and 3) planting native vegetation. Use of split rail fencing around the mitigation site will discourage human intrusion. Nonnative plants will be removed and native species will be planted to create a conifer forest. The trees and shrubs will provide screening of the wetland from residential areas. The plantings, as they grow, will also provide wildlife habitat for native wildlife The mitigation design relocates the buffer lost around the filled wetland to the north and south of the remaining wetland. In these areas, the scattered large trees will be retained. These trees provide immediate structure and habitat improved by plantings of native trees and shrubs with high wildlife value and good potential to screen the wetland from human activities. APPROACH Grading The proposed plan creates wetland by grading down one to two feet adjacent to and within the enhanced wetland. Small areas adjacent to the wetland and within the buffer will also be graded to create a gradual slope (Figure 5). Rough grading will extend one half foot below final grade. The contractor will place topsoil, collected on-site or compost to achieve the final grade. Portions of the existing buffer not graded will either be spot sprayed or grubbed to remove sod for planting. No spraying or grubbing will occur within ten feet of any trees larger than eight inches in diameter. Three inches of mulch, compost or bark will be added to graded or sprayed buffers areas to reduce invasion by nonnative plants and to assist with water retention. The proposed plan utilizes two small berms down slope of wetland areas. These berms will be composed of gravel spalls and dirt. The berms will help to retain water in the wetland and provide a means of adjusting water height and wetland hydrology, should any adjustments be necessary. One piece of woody debris will be placed in the wetland and two in the buffer. These pieces of wood will rot and provide habitat for salamanders and small mammals. Planting The proposed plant schedule uses the palate of species found in wetlands in the Puget Sound foothills (Table 5). Sitka spruce will promote a more rapid re-establishment of the native forest ( climax plant community) that probably occurred in the wetland. Red osier dogwood, black twinberry, ninebark and willows are shrubs with high wildlife food value. Willows provide dense fast growing cover. Welman Subdivision Headwaters Wetland Mitigation Report 12 October 28, 2005 • FFSITE W.ETbAND EA = $-14 SF Scale r "=JO" Slough sedge and small-fruited bulrush will be planted in the emergent patch. Red-osier dogwood, black twinberry, and willow will be planted in the scrub-shrub ring around the emergents. Sitka spruce, ninebark and ladyfern will be planted in the forested areas. Planting areas (Figure 6). Plant numbers are based on complete coverage of graded wetland areas. Table 5.

To increase diversity in the overstory, Western red cedar and Western hemlock will be added as tree species. Additional shrubs species in the buffer will include beaked hazelnut, ocean spray, vine maple, Nootka rose and red flowering currant. These shrub species were selected because of their high wildlife food value. The dense structure of Oceanspray provides good nesting habitat for passerine birds. Plant numbers assume complete coverage of the wetland buffer. Most of the plantings will be in clumps of threes (see planting detail, Figure 7). Plantings will favor Western red cedar, Western hemlock, and Oregon grape in the shadier parts of the site. Irrigation Nursery stock experiences consistent watering, typically twice weekly, and lacks the root development of naturally established plants. Therefore, some initial watering of planted nursery stock is necessary for survival. To wean the nursery stock of the need for watering, watering levels are reduced over time. During the first year, between July 15th and September 15th, watering will occur weekly from an irrigation system or truck. During the second year watering will occur every other week, during the same period. During the third year watering will occur only during extended drought, defined as no storm event over 0.1 inch for three weeks. No watering will occur on the forth or fifth years.

In addition, the proposed plan uses native species with high wildlife value. • Hydrologic: The proposed plan improves Hydrologic functions by creating a small area that will detain water reducing the potential for stream scour and flooding downstream and by preventing mowing of the area and increasing the density of uncut persistent stems in the wetland. • Water Quality: The proposed plan improves Water Quality functions by increasing stem density and by deposition of sediment caused when water remains in the wetland area longer. The proposed mitigation design will improve the following buffer functions. • Habitat: The proposed plan improves Habitat functions by creating a native mixed conifer and deciduous forested buffer with greater structural and vegetative diversity replacing a grass dominated buffer with scattered large trees. • Screening: The increased shrub and tree density will more effectively screen wildlife using the wetlands from nearby human activities. • Human intrusion: The proposed plan will reduce human intrusion by planting shrubs and fencing around the mitigation site. MONITORING PLAN The mitigation area will be monitored one, three and five years after construction. The monitoring will include the created and enhanced wetland and buffer areas. Monitoring will determine if the performance standards have been met. If the performance standards have not been met, the contingency plan described in this report should be implemented. Welman Subdivision 18 Headwaters Wetland Mitigation Report October 28. 2005 Objective 1: Establish Wetland Hydrology. The wetland creation site will provide ground or surface water inundation or saturation sufficient to support the wetlands. Performance Standards: Years 1 and 3 The soils will be saturated to the surface, for a consecutive number of days greater than or equal to 12.5% of the growing season during a normal year. Wetland hydrology will be determined using shallow pits or indicators of wetland hydrology, as listed in the Washington State Wetlands Identification and Delineation Manual (Ecology 1997). Year5 The wetland areas will be delineated using current methods to assure that the mitigation site contains 2,100 square feet of created and enhanced wetland. Monitoring: Between February 1 and April 30th of each year of monitoring, a wetland ecologist will verify the berms are functioning and check and document the site for indicators of wetland hydrology. On year five the wetland ecologist will delineate the wetland and measure with tape and compass the area of the enhanced and created wetland. Objective 2: Establish Wetland Soils. The wetland creation area will have soils capable of supporting wetland vegetation. Performance Standards: At least 80 percent of the soil test pits will have soils conducive to wetland creation in the top 12 inches. If this criterion is meet on year one, no further monitoring is necessary. Monitoring: After construction, three soil pits (sites selected at random) will be dug to 12 inches and examined for soil texture and consistency. At least 80 percent of the top 12 inches will be silt, loam, or peat soils conducive to wetland creation. Objective 3: Establish Native Wetland Plant Community. Plant native wetland plants in the wetland to increase the rate and favored establishment by native species. Welman Subdivision Headwaters Wetland Mitigation Report 19 October 28, 2005 Performance Standard: At least 80 percent survival of plantings after the first year and 10, 25 and 50 percent cover in buffer mitigation areas after 1, 3 and 5 years. Less than 10 percent areal cover by non-native invasive species (Table 7) on any year. Monitoring: After installation, the woody plants will be flagged. Monitoring will involve counting the number of tagged plants and herbaceous plants that survive in sampling plots. Percent survival will be calculated by dividing the number of survivors by the number planted. Percent cover will be determined along three permanent transects established in the wetland areas. Percent cover will be determined using the line transect method Elzinga 1998. Woody species and nonnative species cover will be tallied by species, herbaceous cover will be tallied by plant community types, i.e. velevetgrass, bentgrass and red fescue community. Table 7.

Plant native upland plants in the buffer to increase the rate and favored establishment by native species. Performance Standard: At least 80 percent survival of plantings after the first year and 10, 25 and 50 percent cover in buffer mitigation areas after 1, 3 and five years. Less than 10 percent areal cover by non-native invasive species (Table 7). Monitoring: After installation, the woody plants will be flagged. Monitoring will involve counting the number of flagged plants that survive. Percent survival will be calculated by dividing the number of survivors. Percent cover will be determined along three permanent transects established in the buffer areas. Percent cover will be Welman Subdivision 20 Headwaters Wetland Mitigation Report October 28, 2005 determined using the line transect method Elzinga 1998. Woody species and nonnative species cover will be tallied by species, herbaceous cover will be tallied by plant community types, i.e. velevetgrass, bentgrass and red fescue community. CONTINGENCY AND MAINTENANCE PLAN If the mitigation area has more than 10 percent cover by nonnative species, maintenance workers will hand weed the mitigation site. The workers will remove nonnative and invasive plant species listed in Table 7. If the mitigation site does not achieve the stated performance standards, a wetland ecologist will examine the site to determine the probable cause of the failure. If the plants die, possible causes could include disease, dehydration, flooding, or lack of nutrients. Possible solutions include replanting with different plant species, replanting with relocation, or temporary irrigation. If the wetland soils are not appropriate, soil amendments could be added to provide a better substrate. If water stands in the wetland to long or not long enough, the height of the berms can be adjusted as necessary. CRITICAL AREA TRACT The mitigation site will preserved as a Critical Area Tract. Signs and fencing will delineate the Critical Area Tract. In addition, survey stakes, using iron or concrete markers shall delineate the critical area tract (KCC 21A.24.160). The Subdivision Site Plan includes the Critical Area Tract and will be recorded on the title ofrecord (KCC 21A.24.180). IMPLEMENTATION SCHEDULE Mitigation site grading is planned for the summer of 2006 and planting is planned for the fall of 2006. MITIGATION COSTS/BONDING The total estimated mitigation cost is $18,250 (Table 8). Grading costs, $750, assume no equipment mobilization costs, because the heavy equipment will be on-site. The grading cost estimate assumes the soil removed will be used on-site and there will be no disposal costs. Storm Lake Growers and Sound Native Plants price lists were used to determine plant costs. Compost costs are based Cedar Grove compost prices to cover half the buffer area (all graded or sprayed areas). Irrigation costs provided are a rough estimate and will Welman Subdivision Headwaters Wetland MltigaUon Report 21 October 28, 2005 vary with the method of irrigation used. Monitoring costs will total $6,000. Based on these costs, a bond will be established with King County to assure the mitigation plan is successfully implemented. Upon completion of the monitoring and submittal and review of the monitoring plan, the bond shall be released. $6,500 $3,000 $2,000 $6,000 $18,250 REFERENCES Adamus, P.R. and E.J.

Dream Craft Homes is proposing to divide the property into lots. A small wetland exists on the property. This critical area report documents the delineation of the wetland on the property. 1.1 PROJECT SITE This 3.5-acre site is located on the hill southeast of Renton at 18147 116th Avenue SE (Figure 1 and 2). The majority of the property is mown grass fields with a small grove of Douglas fir and big-leaf maple trees. An existing residence is located in the center of the property with access from 1161h Ave SE. A Category 4 wetland is located in the north and northeast areas of the property. 1.2 PROPOSED PROJECT Dream Craft Homes is proposing to short-plat the property into lots for single family residential homes. 1.3 METHODS The wetland investigation was conducted using the "Routine Determination Method" described in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology [Ecology] 1997). The methodology is consistent with the methods in the Corps of Engineers Wetland Delineation Manual (Corps of Engineers 1987). This method uses field characteristics to identify the presence of three wetland parameters (wetland vegetation, hydric soil, and wetland hydrology). • Wetland Vegetation is present when the plant community is dominated by species typically found in wetlands. • Hydric soil is considered present when the soil color, soil structure and/or amount of organic matter are characteristic of soils inundated for long periods of time. • Wetland hydrology is present when the soils are saturated to the surface for at least two weeks during the growing season (typically from March 1 to October 31 ). Details of the methodology used and the characteristics that define wetland vegetation, hydric soils and wetland hydrology are provided in Appendix A. Wetlands within the project site were delineated and flagged on July 13, 2005. Wetland boundaries within the property boundary were surveyed and these survey boundaries are shown in the figures. Wetland boundaries that extend offsite were flagged and measured using a tape and compass. Datasheets for these delineations are provided in Appendix B.

The details Welman Property CAR Report 3 Headwaters September 20, 2005 'I ' ; 2.0 GENERAL FINDINGS WETLANDS One wetland (A) was found on-site (See Table 2 and Figures 3 ,4 and 5). Wetland A was fiagged and surveyed on September 13, 2005. Datasheets are provided in Appendix B. The wetland meets the criteria for a Palustrine wetland with emergent class (Cowardin 1973). The wetland meets Slope class using the Hydrogeomorphic Classification System (Ecology 2004). Wetland A was categorized using the revised Washington State Wetland Rating System (Ecology 2004) as a Category 4 wetland with a habitat score of 5 (Appendix C). Category 4 wetlands require a 50-foot buffer in King County. Buffers can be reduced by 25 feet with implementation of appropriate mitigation measures including directing lights away from the wetland, covenants limiting pesticide use, fencing around wetland and enhancement of wetland buffer through weeding non- native plants and planting native plants.

Welman Property CAR Report 7 Headwaters September 20, 2005 .', APPENDIX A: ROUTINE DELIENATION METHODS Welman Property CAR Report 8 Headwaters September 20, 2005 ROUTINE DELIENATION METHODS The wetland investigation was conducted using the "Routine Determination Method" described in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology [Ecology] 1997). The methodology is consistent with the methods in the Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987). This method uses field parameters to identify the presence of three wetland parameters (wetland vegetation, hydric soil, and wetland hydrology). For each of these parameters, specific criteria to identify wetland versus upland sites have been established. This multi-parameter approach provides a logical, technical basis for determining wetland boundaries. Wetlands were classified according to the U.S. Fish and Wildlife Service (USFWS) Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979). PRELIMINARY INVESTIGATION Probable locations and likely locations for wetlands are typically identified prior to the field investigation by examining soil surveys for areas with mapped hydric soils, national wetland inventory maps and local critical areas maps. Air photos are also often used to identify potential wetland areas. FIELD INVESTIGATION Wetland boundaries were delineated by characterizing a series of sample sites along a transect perpendicular to the hydrologic gradient. Generally sample sites that meet two of the three major wetland criteria are considered wetland. Field characteristics of sample sites on each side of the wetland boundary are evaluated to determine the characters (plant species, soil characteristics, or hydrologic indicators) that best characterize the wetland or upland edge. The wetland/upland boundary is extrapolated beyond the transect using these specific characters. On difficult or large wetlands, several transects may be used. Potential wetlands identified in the preliminary investigation are examined for all three of the wetland parameters. Other upland areas are typically examined by running parallel transects through the property and around the perimeter and looking for visual indicators of wetlands. PLANT COMMUNITY ANALYSIS A plant community is considered to have wetland vegetation when the prevalent vegetation is consists of plants adapted to wetland conditions. Plant communities on the site were examined for the presence of wetland plants. Plant species have been categorized according to their frequency of occurrence in wetlands (Wetland Indicator Status; Table 1). Plant communities dominated by species commonly found in wetlands meet the technical criteria for wetland vegetation. Welman Property C/\.R Report 9 Headwaters September 20, 2005 Comprehensive analysis of wetland plant communities is sometimes incorporated to distinguish wetland from non-wetland plant communities for borderline sites. This comprehensive method weighs plant species by their Wetland Indicator Status and percent cover to provide a more precise characterization of the plant community. Table 1. Plant Indicator Status CATEGORY Obligate Wetland Plants Facultative Wetlands Plants Facultative Plants Facultative Upland Plants Obligate Upland Plants SOIL ANALYSIS SYMBOL OBL FACW FAC FACU UPL DEFINITION Plants that almost always (>99% of the time) occur in wetlands, but which may rarely (<I% of the time) occur in non- wetlands. Plants that often (67 -99% of the time) occur in wetlands, but sometimes (I - 33% of the time) occur in non- wetlands. Plants with a similar likelihood (33 - 67% of the time) of occurring in both wetlands and non-wetlands. Plants that sometimes (I -33% of the time) occur in wetlands, but occur more often (67 -99% of the time) in non-wetlands. Plants that rarely (<I% of the time) occur in wetlands, but almost always (>99% of the time) occur in non- wetlands. Soils are considered hydric (wetland) when the morphology in the top 12 inches is indicative of soils that are frequently saturated to the surface. Soils test pits dug on site were examined for hydric soil characteristics. Gray soils, grayish soils with rust-colored mottles (spots or blotches) and deep organic soils are indicative of wetlands. Gray soils typically develop when mineral soils are inundated. Lack of oxygen reduces magnesium and iron compounds in the soil to a gray color. Mottles form in seasonally saturated wetlands when fluctuating water levels trap air pockets in the soil. The air pocket allows magnesium and iron compounds in the soil to oxidize forming a rust-colored spot. Deep organic soils form if inundation prevents decomposition and organic debris accumulates. Soils that have a gray, grayish and mottled, or a deep organic soil layer in the top 18 inches usually meet the technical criteria for hydric or wetland soils. The Munsell Soil Color Charts (Kollmorgen 1988) Welman Property CAR Report 10 Headwaters September 20, 2005 were reviewed to determine if the mineral soils showed wetland coloration or other traits of wetland soils. Sandy soils do not typically posses the hydric soil characteristics listed above. Hydric sandy soils usually demonstrate one of three characteristics: high organic matter content on surface, organic streaking of subsurface horizons and presence of organic pans. The following soil indicators were considered indicative of wetlands. • organic soils, • histic epipedons (6" organic layers), • sulfidic materials, • aquic or peraquic moisture regimes, • direct observation of reducing conditions, • gleyed (chroma of 0, low chroma (chroma of 1), and low chroma/mottled mineral soils (chroma of 2 with mottles), • iron and manganese concretions, and • coarse-textured or sandy hydric soils that have a high organic matter content in the surface margin, dark vertical streaks of organic matter in subsurface horizons, or organic layer at or near the water table. HYDROLOGIC ANALYSIS Hydrology on the site was examined by looking for inundation, soil saturation and shallow groundwater tables. The benchmark for wetland hydrology is the presence of soil saturation to the surface for at least one-continuous week during the growing season. In Western Washington, the growing season typically extends from March 1 to October 31. Routine delineations are commonly completed during a single site visit and the duration of inundation must be estimated based on existing groundwater levels, recent precipitation, field site characteristics and past experience. Difficult delineations require repeated examination of the hydrology at specific times of the year to determine the most accurate wetland boundary. Primary indicators of wetland hydrology, in descending order of reliability, include: • visual observation of inundation, • visual observation of saturation, • water marks, • drift lines, • sediment deposits, and • drainage patterns within wetlands. Secondary indicators also can be used when hydrology may be absent due to seasonal changes. Secondary indicators include: • oxidized root channels in the upper 12 inches, • water-stained leaves, • information from the soil survey, and • FAC-neutral test. Welman Property CAR Report 11 Headwaters September 20, 2005 AGENCY VERIFICATION All wetland delineations are completed within industry standards. Headwaters' staff delineate wetlands based on existing site conditions during field analysis, information provided by the client and our best professional judgment. Wetland delineations and classifications must be verified by regulatory agencies prior to grading or clearing.

HGM classes resent August 2004 Wetland name or number Does the wetland unit being rated meet any of the criteria below? If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. SP!. Has the wetland unit been documented as a habitat/or any Federally listed Threatened or Endangered animal or plant species (FIE specie:,)? For the purposes of this rating system, "documented" means the wetland is on the a ro riate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are cate orized as Cate or I Natural Hcrita e Wetlands see . 19 of data form . SP3. Does the weiland unit contain individuals of Priority species listed by the WDFW for the state? SP4. Does the wetland unit have a local significance in addition to its/unctions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class o(the wetland being rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form -wes1ern Washington version 2 2 August 2004 Wetland name or number Classification of Wetland Units in Western Washington I. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? ~ go to 2 YES -the wetland class is Tidal Fringe Jfyes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES-Freshwater Tidal Fringe NO-Saltwater Tidal Fringe (Estuarine) if your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. if it is Saltwa1er Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (seep. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. ~dwater and surface water runoff are NOT sources of water to the unit. ~goto 3 YES -The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores ofa body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m)? @-goto 4 YES -The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? v'Ihe wetland is on a slope (slope can be very gradual), :::::::;zfhe water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheet/low, or in a swale without distinct banks. The water leaves the wetland without being impounded'? ~-NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <Jji diameter and less than I foot deep). f!!§Jgo to 5 YES -The wetland class is Slope Wetland Rating Form -western Washington version 2 3 August 2004 Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? ~-The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river ~-The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. · @-go to 6 YES -The wetland class is Riverine 6. ls the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the i~r of the wetland. ~ go to 7 YES -The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious n~l outlet. C;/-go to 8 YES -The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRJBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. Jfthe area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. Depressional + Riverine along stream within boundary De ressional + Lake.frin e Salt Water Tidal Fringe and any other class of freshwater wetland wetlands with special characteristics lfyou are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

For clarification, I think the math with a 5' dedication adds up to 35' on the west side rather than 40' which means the City is thinking that 70' total is an appropriate ROW width for that classification road were it improved full width per the list below. Going through the listed improvements I actually come up with 33.5' minimum of ROW width each side of centerline to accommodate the listed improvements assuming 11' wide travel lanes and a 12' wide turn lane. This leaves an extra 1.5' of ROW behind the sidewalk assuming 35' of ROW. Please note that the approved p-plat does not indicate a 6' planter strip which is not required by King County under the 1993 KCRS nor does it indicate any additional ROW dedication. Without the planter strip width the existing 30' on our side of 116'" is more than adequate for the required pavement section (22' on our side-112 the 12' turn lane, 11' travel lane and 5' bike lane) along with a 5' wide sidewalk. These improvements along with the .5' width for the vertical curb add up to a minimum of 27.5' of ROW leaving 2.5' of the existing ROW behind the sidewalk. Looking at the approved p-plat, dedication of the 5' of ROW the City is requesting will result in the loss of one lot along the south property line and adversely impact lots 11 and 12 by reducing their depth to 80'. This is problematic for my clients' home plan for this width lot (40') which requires 85' minimum lot depth to work correctly. 80' results in the rear patio being right up against the rear fence. I light of the above, I would like the City to re-evaluate its' request for dedication of an additional 5' of ROW. Thank you. Michael J.

As we discussed, my client's intent is to submit plans for engineering review for this project sometime in the next several months. Confirming what we discussed, in response to my questions about: 1. What jurisdiction will perform the engineering review, King County or City of Renton? 2. Will the City be satisfied with the existing 30' of ROW for our side of 161 h Ave. SE (30' both sides) even though County Road Standards would require 42' for that classification road? As I understand it, your responses were that the City would perform the review (I assume that City formatting for the plans will be required) to County Road (1993 KCRS) and Drainage Standards (2005 KCSWDM) and that the City is not likely to require additional ROW since the improvements that are mandated by the plat conditions will fit within the existing ROW.

Detention wi!1 be provided for in a vauH on site. \/\/ater quality will be done with a wet vault ur:der the proposed detention vault. This report addresses the storrr draina9e issues assoc;ated with the subdivision of the property. and construction of the new homes and access roads The design stand~1rds addressed for this report are cont:iined in King County Code and the Kln9 County Su1face Water Design Manual. Review of the 8 Core Requirements and 5 Special Requirements of the 1998 King County Surface Water Design Manual SOA has reviewed the Core anri Special Requ;rements 1n Chapter 1 of the King County Surface Water Design Manu2I. and addresses each cf the requirements c1s follows: Core Requirement No. 1 -Discharge at Natural Location Currently the site discharges to the northwest and southwest corners of the site Discharge to the norH1west 1s through a small swale, which drains into the Emerald Glen subclivis1on, adJ3cent and to the west. This swale has been identified as u Class~ \Netland. Disct:ar9e frorn the southwest corner of the site travels via overland flow to the southwest corner of the site, Frorn here storrnwater travels via overland flow through an adiacent residential lot in the Walhaven Plat before entering the conveyance system located within SE 186r" Street. From here runoff travels west down SE 186"' Street to 1141 "' Avenue SE. where it turns north and Joins with the runoff that exits the site along the northwest corner. Runoff is then routed through a storrnwatel" detention facility built for the Ernerald Glen subdivision, This 1s a multiple natural discharge and a single threshold discharge area. Runoff from the developed site will be collected and conveyed via a tight ime sysiem to a detention vault located in the northwest corner of the s,te The runoff will exit this vault and be conveyed to the northwest property line and discharged into the existing Class 4 Wetland, The proposed pro1ect will discharge stormwater from the entire site to !he northwest corner of the property. A drainage ad1ustment will be requested for this change, Core Requirement No. 2 -Offsite Analysis Task 1: Define and Map Study Area This pro1ect is located west of 11 ii" Avenue SE. in unincorporated King County, Washington, The property address is 18417 116''' Avenue SE, Renton. The pro1cct consists of one tax parcel: 3223059033, The property 1s approximately 3.24 acres. The propertv will be divided into 25 residential lots, All of these lots will gain access from a newly constructed public road lhat ruris :hmugh the subdivision, one access on 116l; Ave SE The properties to the north. west. and soul11 Hre zoned R-8, The property adJacent and to the west, known as Emeraid Glen. was platted in 1996, and is fully bu,11 out The properties to the south, along SE 186" Street, have been developed into single-family residential iots. To the north, there ae some larger, undeveloped parcels, which arc a'so zoned R-8. The properties to the c;::ist of 115·,, Ave SE are zoned R-6. and are partially developed. with severni hemes on !c1rge parcels -----,------------------------------,·------ WELMAN SUBDIVISION Level One Downstream Analysis March 16, 2006 The analysis of the basin b:x1ndary indicates that the project is in the B!ack River Drainage Sasin. See Figure 1 for 8 vicmity map of the pro1ect and Figure 2 in (both in Appendix A) for an existi1g site survey of tre proJect. Figure 3 m Appendix A shows the oroposed site plan for the development. There 1s an existing houses and associated outbuildings located on several parcc!is. All of the existing structures are to be dernciis!1cci C1L1nng plat construction.

A wetland report. completed in Aprii 2005 by Habitat Technologies. was provided to us by the property owner. The wetland report indicates that a small Category 4 Wetland is present on the site. Altmann Oliver Associates (AOA) was retained to conduct a field visit. and to review the wetland report and address the wetland classification and provide guidance related to wetland buffers and potential impact and mitigation alternatives. It appears that the wetland could be filled, with mitigation measures on site (creation of add1t,onal wetlands), and that the buffer width could be reduced to 25· with buffer enhancements. From our site visit. there does not appear to be any streams, steep slopes, or wildlife habitat on the site • Streams and 100 Year Flood Plains --There are no streams or flood plains mapped on site • Erosion Hazard Areas -There are no mapped erosion hazard areas on site. • Landslide Hazard Areas --There are no landslide hazard areas mapped in this area. • Seismic Hazard Areas -This site is not within ,n a mapped seismic hazard area. • Coal Mine Hazard Areas-~ None mapped 1n this area U.S. Department of Agriculture.

The field investigation covered approximately% rnile dovvnstrcarn of the site Task 4: Describe the Drainage System, and its Existing and Predicted Problems Upstream Drainage Analysis: This site is iocc1ted near the edge of the Black R!ver Drainage Basin There is no upstrearn runoff that enters the site. On-Site Drainage Analysis: The property is approximately 3.24 acres in size and has approximately 400 LF of frontage on 116u, Avenue SE. The site generally slopes to the north and west The southern half of t/1e sit8 is on a relatively fiat. grassy ;AatRau and contnins an existing house, a garage, and a carport. which are !ocated in the center of tile property. The northern half of the property is also characterized by largely grass areas. and slopes down from tho southern plateau toward a small swalc. which drains into the subdivision adjacent and to \he wesL This swalc has been identified as a Class 4 Wetlancl and is add1·essed in the foliowing pages of this repo,·t The maJority of the site is grassy pstme. with scattered trees of varying size throughout the site. Please soo Figurns 2 & 3 for aerial views and general topoqraphical information. The property appears to be frequently maintained, and the grass mowed regularly. Downstream Drainage Analysis: See the attached off-site Analysis Dra1na9e System Table and map for a more detailed description of the drainage system downstream of the proposed project. This information is presented in Appendix B of the report. Section 1: The rnaJority of the site drains towards the northwest to a swale classified as a Class 4 wetland, located near tr,e western boundary of the site Ttiese wetlands drain offsite to the west where they drain into the enclosed drainage system for the Emerald Glen Plat. Th:s system conveys southwest down SF 185'r Place, then south down 114·'' /\venue SE Section 2: Runoff then turns west and enters a <Jetcnt,011 pond constructed as part of the Emerald Glen Plat. Section 3-4: After leaving the detention pond runoff travels via overland flow through several private properties before 1,eod,ng north along 1121 h Ave SE to the limits of the downstream analysis. Drainage Complaints: >::.;E;vie?J of the King County Drainage complaints indicates that there are fifteen relevant drainage complaints recorded :1<iw•1s:rca:n of Hie site within the last 10 years.

The Gilbert's property is below road grade, and the ditch from the south ends near his south property line and the ditch on the north starts up at about his north property line. Mr Gilbert said that he did not have a problem at the time with drainage, however when we have heavy rains (2-3 yrs ago) he experienced flooding in his basement. There is a ponding area between the road and his laurel hedge (photo 1 ), and he also built up a small berm on the house side of the hedge, to further control the drainage. He also put in a 4" ADS to drain from the bermed area to the side of the house. Mr Gilbert says that as long as a x-culvert under 116th that outlets to his property remains closed, he doesn't think he'll have a problem. Said to have been covered when road was overlayed.

The area appears to be were a depression existed prior to development and an casement was established on the plat recording to drain the area into the plat drainage sy_i;tem. The should be a swale about 2 feet deep according to the drainage calculation. There has been a 8" perfpipe interceptor drain installed in a drainage easement along the very east edge of Lots 23.30 of the plat. The swale easement appears to be about 25-35 feet from the same line. The Swale in not in existence in the yard that I looked at. To relieve the problem a new system will have to be constructed or the swale reestablished Lot 29 Lot28 Lot27 Lot26 Lot25 Lot24 Lot23 Drainage Easement per Plat ' ' .

She is calling regarding a ponding problem in the back of the home at the site location listed above. Findings I was able to meet with the son, John Arreola (235-8712), of the homeowner al the problem site. He showed me the ponding area at the back of the home. He was planning on building a fence at the back property line. The previous investigation showed there should have been a 10' private drainage easement in the back of 7 lots. There should have been an open swale close to the back end of each of the lots. Currently there is an 8" perf pipe running parallel to the fence along the back of each property. Arreola has installed a small plastic CB at the starting point of the pipe in the back of his parent's lot. The pipe was not wrapped in pervious doth prior to its installation. I am sure this will result in silts and fines getting into the pipe at some future point. I checked the other lots and was not able to find a CB in any of them. Every one of the homes (lots 23-27, 29) have built over the original swale location. There are gardens, storage sheds, children's play areas and other constructed items in every yard. TI1is problem is further complicated by the a public easement granted to King County to maintain the grass-lined swale. J met with Jackie Little, KC Roads, per her request, to show her what our investigation would determine. I showed Jackie all of the construction done in the swale easement and explained to her that this type of work plus the installation of the 8"perfpipe was obviously a concerted effort by all of the homeowners. It would be very cost prohibitive to go back to the previous, if ever there in the first place, system. Impact Score = 120 Options and Discussion • Flooding or erosion -Flooding • Affects mainly private property -Yes • Caused hy more than one adjoining single family parcel or not a code violation -Y cs and Maybe • Caused by later upstream development -No. Proposed Solution I don't feel there is anything that can be done for this problem. The easement is a private easement although for the public. Having installed the buried 8" perf pipe shows the neighbors obviously knew what they were doing and have made a choice to remove the open swale. I do not believe KC has any responsibility to maintain the pipe as this was not included in the original easement language. Maintenance of the pipe lies with the property owners.

The original drainage plans for the short plat show the open d.itch system on the west side of 121st Place SE was designed for infiltration/retention as well as conveyance. The open ditch conveys runoff to a control structure located at the intersection of 121st Place SE and SE 192nd Street. The open ditches have 12-inch driveway culverts located intermittently, connecting them to one another. The complainant is concerned with the recent development in the area and the intrusion upon the open ditch system. Last year the resident at 19133 121st Place SE filled in the open ditch fronting the property as part of their detached garage addition. A 6-inch perforated conveyance pipe was installed before the ditch was filled. According to the complainant surface water from the open ditches overtopped the roadway and flowed east affecting the residents living on the east side of 121st Place SE. This summer the residents at 19125 1215 t Place SE are filling in their open ditch while adding a 6-inch perforated conveyance line connected by a series of lawn drains as part of their detached garage construction. The complainant believes the integrity of the drainage system will be severely compromised and future flooding may result from these activities. FINDINGS: Since the problem meets all of the NDAP project criteria listed below, it qualifies for and has been investigated under the NDAP program. • The problem site is within the SWM service area and does not involve a King County (KC) code violation. 1 • The problem site shows evidence of or reported localized flooding, erosion and/or sedimentation within the off road drainage system on private residential and/or commercial property due to later upstream development. • The problem is caused by surface water from more than one adjoining property. SOILS: According to the KC soils map, the site is located in the following soil association: ALDERWOOD ASSOCIATION: Moderately well drained undulating to hilly soils that have dense, very slowly permeable glacial till at a·depth of 20 to 40 inches; on uplands and terraces. OPTIONS AND DISCUSSION: 1. An enforcement letter can be sent to the aforementioned residents who filled in the open ditch system. The letter will ask for their cooperation in removing the conveyance systems so the open ditches can be restored to function as designed. KNFORCJIMENT IMPACT SCORE 40 PROPOSED SOLUTION: An enforcement letter will be sent.

'!be downspouts and other drainage appeared to be connected into an infiltration or other drainage system. The area of concern had been regraded and filled so that it was higher that his yard and water is running from some area toward him. The two closest downspouts were not connected and water would flow onto the ground. I told Mr. Moore that this is a problem that the building inspector would have to deal with as the houses may still be under permit. I told him that we would send his concerns over to them to see if they needed to correct any construction defects.

The rental gets water in the crawl space during large storm events; and the side yard is saturated with \Vater. I explained to Mrs. Lancaster that the neighbor is not required to install drainage and that normal runoff that was not directed. had to be accepted and handled by tbe Lancaster's.

Ms. Irwin experiences a wet rear yard during the rainy season and complains that water is flowing from properties to the east onto her property. In particular. she says, water is ,!raining from a paved area serving Lot 11 to the east. Ms. Irwin assumed the driveway, which accesses Lot 11. was a County right-of-way and therefore we were responsible for water coming from the east. I explained to her that it was a private <lriveway that serves Lot I I and therefore was a private drainage problem between two property owners. I told her I would look at the design of the drainage system for her development and if there were any lines in or near her rear yard l would be back out to investigate. There are no drainage lines in or near her rear yard per the as- built for the development of Emerald Glen. At the time of my site visit there was no water in the rear yard. However, there was saturation of the rear yard. Grass growth was moderate in its density and half of it was yellow. Per the complainant water "gushes" out of an area of plantings along her rear property line. I could find no direct source outletting water. From the way the property behind her is graded it is possible that water is sheetflowing across their lots and onto hers . .... .... f .. ~ i $ \ • \ • \ • • ' Area of saturated t!TOUnd 1,2,3 ' • ' • ' • • • Drainage Compl!aint Number 2002-0553 WELMAN SUBDIVISION Level One Downstream Analysis March 16, 2006 -· '1-i,sJO KLNG COUNTY WATER AND LAND RESOURCES DIVISION ~1,./-z...-DRAINAGE INVESTIGATION REPORT ·A1 /.V \ A.

Complaint 2002-0553 Perigen Investigated by Andrew McDonald on August l 3. 2002 Christine Perigen, Project Manager/HOA President for Chinquapin Homeowners Association, contacted King County WLRD in regards to Tract A of Chinquapin Ridge. Ms. Perigen was under the impression thai Tract A was a King County owned and maintained NOPE/drainage tract. Tract A is in fact ovmed and maintained by the Bomeowner's Association. The property owner of Lot 13, which is adjacent to Tract A, became alarmed with some settling occurring in their yard. The assumption was that Tract A, being a drainage easement and therefore conveying water that might erode the hillside. was the culprit. From the original topography shown on the site, lot 13 appears to have been re-graded with a sizable amount of fill. Fill was brought in under a revision to permit issued on site. K9208130 was described as a structural revision and a revised site plan. Upon meeting Christine Perigen and the. property owner of Lot 13, I provided them with a copy of the drainage plan and a copy of the topography showing the site prior to construction of the residence. I referred Ms. Perigen and the homeowner to DOES to obtain a copy of the building permit to dctennine what was placed on prope1ty in the way of fill. I also suggested that they may want to hire a geo-technical consultant to determine the cause of settling of soil on site. . . . . .... •••• •••• .......... . . . . . ························ .... ~~~~~ ....

DIVISION INITIALS -SA B NTS DETAILS OF INVESTIGATION: ~ On site 12-05-03 to investigate a report of backyard/crawlspace flooding. Met with Kay who showed me the area that floods on her property. According to Kay the storm water in her backyard would drain off her property at it's lowest point near the back of the garden into the neighbor's field (before it was developed). She claims the flooding did not happen until the property owners in the development to the South of her began to fill in a drainage swale she claims existed to drain her property. Since the filling of the swale her yard pools 1+ feet in depth until it infiltrates into the ground. Kay claims when the flooding occurs he crawlspace under her home fills with approximately 4" of water and smells like sewage, possibly from the septic system to the North. I looked for the swale by looking over the fences of the new homes but did not see any evidence of a swale except the CB on lot 4 (11620). According to the approved plans for the development to the South (Lynden Place), there is not a swale but a interceptor trench in the 1 O' drainage easement between Lots 2-7 and the Smith's property. This interceptor drain flows to a CB and drains South to the pond for the development (092516). The plan profile for the Interceptor trench shows washed rock filled to the surface yet no washed rock was visible and appeared to be covered with grass or landscaping which could be affecting the function of the trench. This appears to be a private issue between the Smiths and the owners of Lots 2-7. SKETCH: ------------------------------------------------- ---------: ,---1 Lot 1 : 1 g> : I .. -------. -+r ,, ,.

He gave me a tour of his property. According to Mr. Smith he has lived at this location for about 12 years and has experienced increased yard and crawlspace 11ooding after grading began for the Lynden Place residential development in 1998 and 1999 located just south and downslope of his 1.28 acre property. \Ve inspected the many wet areas of the Smith property including their previously well used garden area located at the south edge of their property. Mr. Smith said they have not been able to use their garden area shown in the attached site sketch since it is too wet and often flooded following rainy periods. This appears to be another impact of the downstream development. My own inspection of the Smith's south yard and newer yards to the south vcnfies what Shawn observed during his site visit: The yards located just south of Smith's property in the Plat of Ly11den Place are raised around the home footprints in order to encourage gravity flow of surface water away from each home. 1 Due to yard landscaping around the new homes with lawns, plantings and associated filling of drainage swalesjust south of the Smiths' south property line, the French drains installed along the north edge of the new Plat may not be ti.mctioning properly. I inspected the drainage system in the Plat of Lynden Place in SE 193rd Street at the southeast comer of lot 4 next to the sidewalk. I observed a small amount of water draining south out of a buried 12 inch drain pipe from the northeast comer of lot 4 south into the street drainage system. This drainage system collects flows from lots 2 through 7 along the north edge of the plat all located immediately south of Smith's south property line. Based on my review of the prcdcvelopmcnt contour site map and my site inspection on January 14, 2004, it appears that surface and shallow groundwater on the lower south edge of the Smith property presently have reduced outlet capacity compared with the area hefore L111dcn Place was developed. POSSIBLE ALTERNATIVES: Install a gravity !low interceptor drainage system at the south edge of the Smith property and tie it into the existing private drainage system catch basin located at the northeast comer of Lot 4 of Lynden Place. The drainage system in Lot 4 drains by gravity from north to south via a buried 12 inch drain pipe that drains into the street drainage system in SE 193"1 Place. A pcnnanent drainage easement would be required from the owner of Lot 4 in order to connect the Smiths' drainage system into the drainage system on Lot 4. PROPOSED SOLUTION: I recommend that this review be closed to our NDA-Q program. 2 Drainage Complaint Number 2004-0745 -----------···-·····--·-·--·----··--·----·-· WELMAN SUBDIVISION Level One Downstream Analysis March 16, 2006 DRAINAGE INVESTIGATION REPORT PROBLEM:~-----INVESTl(i.~TlON RFQl'EST Type .1:CEIVED BY: OK'd bv: FILE No, 2004 Received from: NAME: ~ p~ PHONE (Day) (~dJ; (Eve) £d1J.(?J -<AYJ-OJ!O 932-330'3 ADDRl,SS _____ (/Lfl/1 W /~7t/:) (o}f <Ji5 City ~ State __ Zip 9/"CJ'f' LOCATIO;'J or· PROBI.F\1.

The back yard of the Pollards' is sloped toward their home_ The Pollards have had a problem with a wet back yard since moving in, at this time they are getting no water under their home_ They discovered there are two pipes dumping into their yard from the neighboring yard_ These pipes appear to me to be from the downspouts on the house behind them. The Pollards have spoken with the neighbors and they where told the pipes where there when they bought their house, they did not know who may have installed them. It would appear this was done at the time of construction_ These houses where built in the early 70s and the house behind the Pollards is also below the road so it would seem the contractor Just ran the downspout to the lowest and easiest point to get to_ I spoke to Mrs. Pollard about installing an interceptor ditch or a infiltration ditch to catch the water coming off the neighboring lot.

The water level 1n both was the same and it seems that the pipes are not impacted and functioning as they shculd. The water level at the outfall into the Soos Creek drainage was lower today than l?tst week and seems to reflect the water level in the last two catch basins before the outfall The top of the outfall pipe was approx. 2" above the waler level during my visit on G/21/05 The water does flow from there to a ponding area in the Soos Creek drainage The water table in the Soos Creek drainage seems to be high and,. unless the water table goes down. there seems to be nothmg else DOT can do to alleviate the standing water in those CBs as it backs up into the ROW drainage system.

Christina explained to me that Soos Creek Water Department had just informed her that the waterline was not leaking. The area was not wet at the time of inspection but the seeping was very evident by the discoloration on the sidewalk below the water meter box. This appears to be a private property issue. I explained that th i s problem was possibly a groundwater issue due to the high groundwater table in the area and that the water was using the potable water service ditch line as a conduit to the surface. I suggested to her to install an interceptor trench and direct it to the ditch to the North of her property.

The proposed project will subdivide the site into 25 single-family housing lots. In addition to the roadways, the proposed project will include all utilities and other improvements necessary to accommodate the new lots. Detention will be provided for in a vault on site. Water quality will be done with a wet vault under the proposed detention vault. This report addresses the storm drainage issues associated with the subdivision of the property, and construction of the new homes and access roads. The design standards addressed for this report are contained in King County Code and the King County Surface Water Design Manual. Review of the 8 Core Requirements and 5 Special Requirements of the 1998 King County Surface Water Design Manual SDA has reviewed the Core and Special Requirements in Chapter 1 of the King County Surface Water Design Manual, and addresses each of the requirements as follows: Core Requirement No. 1 -Discharge at Natural Location Currently the site discharges to the northwest and southwest corners of the site. Discharge to the northwest is through a small swale, which drains into the Emerald Glen subdivision, adjacent and to the west. This swale has been identified as a Class 4 Wetland. Discharge from the southwest corner of the site travels via overland flow to the southwest corner of the site. From here stormwater travels via overland flow through an adjacent residential lot in the Walhaven Plat, before entering the conveyance system located within SE 1861h Street. From here runoff travels west down SE 1861h Street to 114th Avenue SE, where it turns north and joins with the runoff that exits the site along the northwest corner. Runoff is then routed through a storrnwater detention facility built for the Emerald Glen subdivision. This is a multiple natural discharge and a single threshold discharge area. Runoff from the developed site will be collected and conveyed via a tight line system to a detention vault located in the northwest corner of the site. The runoff will exit this vault and be conveyed to the northwest property line and discharged into the existing Class 4 Wetland. The proposed project will discharge stormwater from the entire site to the northwest corner of the property. A drainage adjustment will be requested for this change. Core Requirement No. 2 -Offsite Analysis Task 1: Define and Map Study Area This project is located west of 116'h Avenue SE, in unincorporated King County, Washington. The property address is 18417 1161h Avenue SE, Renton. The project consists of one tax parcel; 3223059033. The property is approximately 3.24 acres. The property will be divided into 25 residential lots. All of these lots will gain access from a newly constructed public road that runs through the subdivision, one access on 116h Ave SE. The properties to the north, west, and south are zoned R-8. The property adjacent and to the west, known as Emerald Glen, was platted in 1996, and is fully built out. The properties to the south, along SE 18611' Street, have been developed into single-family residential lots. To the north, there are some larger, undeveloped parcels, which are also zoned R-8. The properties to the east of 1161h Ave SE are zoned R-6, and are partially developed, with several homes on large parcels. The analysis of the basin boundary indicates that the project is in the Black River Drainage Basin. See Figure 1 for a vicinity map of the project and Figure 2 in (both in Appendix A) for an existing site survey of the project. Figure 3 in ----------·-----------------------~-- WELMAN SUBDIVISION Level One Downstream Analysis Appendix A shows the proposed site plan for the development. There is an existing houses and associated outbuildings located on several parcels. All of the existing structures are to be demolished during plat construction. Task 2: Review all Available Information on the Study Area Critical Drainage Area Map • Black River Drainage Basin • Duwamish -Green River Watershed • Duwamish-Green WRIA (9) Flood plain/floodway (FEMA) Maps • There are no mapped floodplains in the immediate area per the available FEMA map. The site is located in Zone X per the Flood Insurance Rate Map (FIRM) map number 53033C0991 F. See Figure 5 in Appendix A for a copy of the FIRM map. Sensitive Areas • Wetlands -Recent site investigations conducted indicate that there is a wetland located on the site. A wetland report, completed in April 2005 by Habitat Technologies, was provided to us by the property owner. The wetland report indicates that a small Category 4 Wetland is present on the site. Altmann Oliver Associates (AOA) was retained to conduct a field visit, and to review the wetland report and address the wetland classification and provide guidance related to wetland buffers and potential impact and mitigation alternatives. It appears that the wetland could be filled, with mitigation measures on site (creation of additional wetlands), and that the buffer width could be reduced to 25' with buffer enhancements. From our site visit, there does not appear to be any streams, steep slopes, or wildlife habitat on the site • Streams and 100 Year Flood Plains-There are no streams or flood plains mapped on site. • Erosion Hazard Areas -There are no mapped erosion hazard areas on site. • Landslide Hazard Areas -There are no landslide hazard areas mapped in this area. • Seismic Hazard Areas -This site is not within in a mapped seismic hazard area. • Coal Mine Hazard Areas -None mapped in this area. U.S. Department of Agriculture, King County Soils Survey • The soil on the site is Ground Moraine Deposits (Qgt). Figure 4 in Appendix A presents the soil survey for the project area. Flow Control Applications Map • The site is located in a Level 2 area of Flow Control. Water Quality Applications Map • The site is located in a Basic Water Quality Treatment Area. Landslide Hazard Drainage Area Map • The site is not located in a landslide hazard drainage area. WELMAN SUBDIVISION Level One Downstream Analysis Task 3: Field Inspect the Study Area A representative of Site Development Associates, LLC (SDA) made a site visit to the property on December 15, 2005. The weather conditions were dry, 35 degrees and cloudy. The field investigation covered approximately Y. mile downstream of the site. Task 4: Describe the Drainage System, and its Existing and Predicted Problems Upstream Drainage Analysis: This site is located near the edge of the Black River Drainage Basin. There is no upstream runoff that enters the site. On-Site Drainage Analysis: The property is approximately 3.24 acres in size, and has approximately 400 LF of frontage on 116u, Avenue SE. The site generally slopes to the north and west. The southern half of the site is on a relatively flat, grassy plateau and contains an existing house, a garage, and a carport, which are located in the center of the property. The northern half of the property is also characterized by largely grass areas, and slopes down from the southern plateau toward a small swale, which drains into the subdivision adjacent and to the west. This swale has been identified as a Class 4 Wetland, and is addressed in the following pages of this report. The majority of the site is grassy pasture, with scattered trees of varying size throughout the site. Please see Figures 2 & 3 for aerial views and general topographical information. The property appears to be frequently maintained, and the grass mowed regularly. Downstream Drainage Analysis: The project site and surrounding vicinity was visited on July 14, 2006. The weather conditions were warm and dry, and no precipitation having recently occurred. No surface flow was visible during the site visit. A brief description of the downstream drainage path is included below. See the Appendix B for an off-site Analysis Drainage System Table and map. The majority of the site drains towards the northwest to a swale classified as a Class 4 wetland, located near the western boundary of the site. These wetlands drain offsite to the west (see photo #'s 1 & 2) where they drain into the enclosed drainage system for the Emerald Glen Plat. This system flows southwesterly SE 185th Place, to 1141 " Ave. SE, which lies approximately 400 feet downstream of the project site. From this point, runoff continues southerly along 1141 " Ave. SE for a short distance, then turns westerly (see photo #3), beneath an access driveway, before entering a detention facility (see photo #4) approximately 625 feet downstream of the site .. The outfall from this pond could not be located, but from the regional topography, and from a prior drainage investigation, it appears that the pond outfalls to the west. A 1 O' drainage easement exists along the back of the lots adjacent to SE 186'" Street. It is likely that this easement contains a conveyance pipe, however, no pipe could be located. It appears that flow continues westerly from the detention facility to 112'" Ave. SE. Upon reaching 112'" Ave. SE, the runoff is intercepted by the public storm drainage system, and is conveyed northerly to a catch basin which lies just north of SE 1841" Pl. From this catch basin, runoff is conveyed westerly to a second, larger detention facility (see photo #'s 5 & 6), approximately 1,400 feet downstream of the project site. The outfall from this detention pond appears to be at the southwest corner of the pond, and runoff appears to be conveyed to the west from this outfall (see photo #7). The remainder of the downstream flowpath is beyond the ;/,-mile distance required for this analysis. ------. --~-----------________ ,, ___ _ WELMAN SUBDIVISION Level One Downstream Analysis Drainage Complaints: Review of the King County Drainage complaints indicates that there are two relevant drainage complaints recorded downstream of the site within the last 1 O years. These complaints are included in Appendix B of this report. Task 5: Addressing Mitigation of Existing and Potential Problems The development of this proJect is not expected to have an adverse impact to the downstream drainage system. Drainage for the 25 lot subdivision will meet King County requirements for detention and water quality. Portions of the Class 4 wetland will be filled as a result of this project. Mitigation measures will be employed to ensure that the remaining wetland will continue to operate hydraulically in the same manor as before the subdivision. A sensitive area tract for the wetland and buffers is provided. There should be no impact to the downstream system as a direct result of this project. Core Requirement No. 3 -Flow Control The proposed project is located in a Level 2 Flow Control Area. The Level 2 Flow Control requires the developed flow rates discharge to the predeveloped flow rates ranging from 50% of the 2-year peak flow up to the full 50-year peak flow. See Appendix C for preliminary detention calculations. The project currently contains two separate discharge locations, however, the two discharge points converge within Y.- mile of the site, so the project is assumed to be contained within a single basin. The project proposes the re-aligning of an existing intersection, on the east side of 116th Avenue SE, near the northeast corner of the site. This improvement is being completed in order to align the intersection with the project's proposed intersection. The east side of 1161 h Avenue SE lies in a separate basin than the project, and the proposed improvements there will add less than 5,000 square feet of new imprervious surface, so no flow control is proposed there. Core Requirement No. 4 -Conveyance System As part of the final engineering design for this project, it will be required to demonstrate that the storm drainage system can convey the peak flow from 25-year storm event, and that the 100-year storm event does not create or aggravate a "severe flooding problem". Core Requirement No. 5 -Erosion and Sediment Control In order to protect the downstream conditions from sediments, several erosion control Best Management Practices (BM P's) from the King County Surface Water Design Manual will be utilized. During and after grading, and during house construction, the site will be stabilized with appropriate BM P's consisting of silt fencing, mulching and hydroseeding. A temporary construction entrance will be installed for construction related traffic. Filter fabric will be placed over catch basin grates. All yard areas will be landscaped. Additionally, limiting earthwork and utility construction activities to dry weather conditions, minimizing area and duration of soil exposure, construction of temporary storage basins and protective dikes to control storm runoff, and stockpiling and sheathing of strippings, will further reduce the potential for silt-laden runoff. Interim measures to be employed during construction will include the construction of sediment basins, the installation of silt fences along the low side of the areas to be cleared and graded, and mulching and hydroseeding of exposed soils after attainment of final grade. Stockpiles will be covered with polyethylene sheathing. Additional erosion control measures by individual builders are recommended during construction of houses. These should include installation of a silt fence at the roadside, placing a bed of builder's sand between the house and the street, and covering stockpiles. WELMAN SUBDIVISION Level One Downstream Analysis Core Requirement No. 6 -Maintenance and Operations See Appendix D for the Maintenance and Operations Manual for the Welman Subdivision. Core Requirement No. 7 -Financial Guarantees and Liability The Financial Guarantees and Liabilities will be required prior to the project being finalized by King County. Core Requirement No. 8 -Water Quality The project will provide basic water quality prior to discharge to the class 4 wetland on the project site. Water quality will be accomplished in a wet vault under the project detention vault. See Appendix C for preliminary water quality calculations. Special Requirement No. 1 -Other Adopted Area-Specific Requirements The project is located within the Duwamish-Green River Watershed, Water Resource Inventory Area (WRIA) 9. Special Requirement No, 2 -Floodplain/Floodway Delineation This requirement does not apply. Special Requirement No, 3 -Flood Protection Facilities This requirement does not apply. Special Requirement No. 4 -Source Controls This requirement does not apply because the project is located in the basic water quality treatment area. Special Requirement No. 5 -Oil Control This requirement does not apply.

The complaint appears to be a Type 1 (nuissance) complaint. The property owner claims that an adjacent property is discharging flow to the complaintant property. King County listed the complaint as a private drainage dispute, and issued standard handouts to the property owner. No further action appears to have been taken by the County. The subject property and tributary properties are in the general vicinity of the downstream analysis, however, neither property appear to be directly in the downstream flowpath. Flow from the Welman subdivision is collected and conveyed around the complaintant property, and it does not appear that the Welman development will have any affect on this drainage complaint.

Irwin experiences a wet rem yard during the rainy season and complains that water is flowing from properties to the east onto her property. ln particular. she says, water is draining from a paved area serving Lot 11 to the east. Ms. Invin assumed the driveway. which accesses Lot IL was a County right-of-way and therefore we were responsible for water coming from the east. I explained to her that it was a private driveway that serves Lot l l and therefore was a private drainage problem between two property o,vners. I told her I would look al the design of the drainage system for her development and if there were any lines in or nc·,ir hn rear yard l would he back out to investigate. There are no drainage lines in or near her rear yard per the as- built for the development of Emerald Cilcn. At the tirnc ofmy site visit there was no water in the rear yard. However, there was saturation of the rear yard. Grass growth was moderate in its density and half of it was yellow. Per the cumplainant. water "gushes" out of an area nf plantings along her rear property line. l could find no direct source outletting water. From the way the property behind her is graded it is possible that water is shcet11owing acrnss their lots anJ onto hers. \ \ \ ' .,...-- Area of saturated 2round 1.2.3 ' • • • • • \ / P~Al~A'e#"" he.~ ,t:;z,:,,-, ,:,Y,€"" ,4r 4,,U su i! /;?/ (/ t f,,,,,,,.., Drainage Complaint 18504 11ih Ave SE No formal drainage complaints are on file at King County for this property. However, during King County's field review for the Welman Subdivision, County staff were apparently approached by the property owner regarding a drainage problem on the property. King County has requested that the property owner be contacted and interviewed regarding their drainage complaint. Site Development Associates contacted Judy Bryant, the property owner, in June of 2007. She indicated that her property was experiencing periodic Type 1 (nuissance) flooding problems. Based on the local hydrologic features, and topographical information available in the area, it is likely that the flooding problem originates east of her property, possibly near the discharge of an upstream detention facility. Ms. Bryant indicated that she had previously lived in the house immediately south of her current residence, and recalls that there is a 1 O' drainage easement across the back of the lots adjacent to her. This was verified on King County Assesor mapping. This easement most-likely contains a conveyance pipe, which is intended to carry flow from west from the upstream detention facility. A pipe could not be located during the field-investigation, and it's possible that it is buried, and not functioning correctly. From my conversation with Ms. Bryant, it appears that flooding has been limited to her yard, and that flooding events are periodic. It was unclear whether a flooding event had taken place within the past year. The property in question lies directly in the downstream flowpath of the proposed Welman development. However, the property is required to meet King County Level-Two flow control standards. This standard is intended to ensure that peak flows and peak flow durations are not exceeded for all flows ranging up to the 50-yr design storm event. With this in mind, the drainage is not likely to be further aggrevated by the proposed development. Location and maintenance of the existing detention pipe in the adjacent lots would be the logical first step in alleviating the problem.
