FAMILYHOUSINM LUA-97-088,SA,ECF REPORT AND DECISION OFJULY 28,1997 Page 2 of 12 1 PART ONE: PROJECT DESCRIPTION/BACKGROUND The project site is currently vacant and includes a portion of the vacated Jefferson Ave. NE. The applicant intends to construct 18 residential units for low to moderate income families. The 18 dwelling units will be distributed in five buildings. Fourteen of the units will be 3-bedroom units and four will be 2-bedroom units. The applicant requested and was granted a waiver from the standards of the Parking and Loading Ordinance. Normally an eighteen dwelling unit multi-family residential project would require thirty- two parking stalls. The applicant will be providing thirty parking stalls. The maximum height of the buildings from the ground to the peak of the pitched roof is approximately 36' - 9". When measured in accordance with the City of Renton Code, which takes into account the sloped site and pitched roof, the tallest building will be approximately 30 feet in height. Both of these heights are well within the maximum height limit for the CS zone which is fifty-five feet. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21 C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: (1) Earth Impacts: The applicant will be developing a vacant parcel of land into a five building, 18 dwelling unit, residential development for families with low to moderate incomes. The site is sloped from the east downwards to the west. In order to prepare the site for construction the applicant will need to level the site. This work could require a retaining wall/rockery structure to be constructed along the north and east boundaries of the project site. The applicant intends to fence the project site. This fencing will reduce the potential of children accidentally falling on the retaining wall/rockery will taking short cuts through the backyards of adjacent properties. A geotech report has been prepared for this project. This report describes the existing soils and makes recommendations regarding the removal of loose surface material and the existing grassy vegetation. The applicant will then be required to provide fill material that can be compacted in accordance with City standards for the building footprints. The amount of fill and cut material has not been calculated by the applicant. However, the project has almost direct access to Sunset Blvd. and City staff does not anticipate that truck traffic will be a significant impact in this area as long as the trucks stay on the major roads and only operate during non-peak traffic flow periods.

FAMILY HOUSINi LUA-97-088,SA,ECF REPORT AND DECISION OF JULY 28,1997 Page 3 of 12 The applicant will need to provide a temporary erosion control plan for this project. This plan will detail how the applicant intends to mitigate for the impacts of wind erosion (dust) and water erosion during the construction phase of the project. The site will be landscaped as the final phase of construction. Proper landscaping of the site will prevent erosion during the operational phase of the project. Mitigation Measures: Temporary Erosion Control shall be installed and maintained to the satisfaction of the representative of the Development Services Division for the duration of the project. Policy Nexus: Mining, Excavation, Grading Ordinance, Environmental Ordinance (SEPA) (2) Air Impacts: Adverse air quality impacts could be associated with the construction and operation phase of this development. Construction impacts would include dust from grading activities and exhaust from construction equipment. Fugitive dust will be controlled by compliance with the temporary erosion control measures. The exhaust from construction equipment is controlled by state and federal regulations. No further mitigation is required for this specific project. Operation phase impacts include the heat source for the proposed buildings and exhaust from the vehicles used by the residents. These impacts are controlled by state and federal regulations. No further mitigation is required for this specific project. Mitigation Measures: No mitigation required. Policy Nexus: N/A (3) Water Impacts: This project is located outside of the Aquifer Protection Area for the City of Renton. There is an existing surface water line in NE 10th Street and an extension in Index Avenue NE. The applicant will need to provide an on-site surface water system in accordance with the King County Surface Water design Manual. The applicant is providing a bio-filtration system and detention vault. Mitigation Measures: No further mitigation is required. Policy Nexus: N/A (4) Police and Fire Services Impacts: Police Department staff anticipate that the proposed project will generate 16.56 calls for service annually. Sufficient staffing exist to provide the required level of service. Fire Department staff note that with the Code-required improvements, sufficient resources are available to respond to the level of service required for this building. The applicant is required to provide a Fire Mitigation Fee of$388 per unit (18 units x $388 = $6,984.00). SITEERC.DOC .

FAMILY HOUSING LUA-97-088,SA,ECF REPORT AND DECISION OF JULY 28,1997 Page 9 of 12 Mitigation Measures: The applicant shall submit a Fire Mitigation Fee of $388.00 per unit (18 units x $388 = $6,984.00) prior to the issuance of building permits. Policy Nexus: Fire Mitigation Fee Resolution, Environmental Ordinance (SEPA) (5) Transportation Impacts: The proposed development could generate an average of 116.46 daily trips. This level of traffic would have a cumulative impact on the existing City circulation system. To mitigate this impact the City has adopted a Transportation Mitigation Fee of$75 per average daily trip. Each unit in this project is anticipated to generate 6.47 average daily trips. The mitigation fee for this project is $8,734.50 (116.46 trips x $75.00 = $8,734.50). The roads adjacent to the subject property, such as Sunset Blvd., carry a significant level of peak hour traffic. In order to mitigate the impact on the existing traffic flows by the proposed construction the applicant should limit construction vehicle movements and traffic revisions to the hours between 8:30 AM and 3:30 PM. Mitigation Measures: The applicant shall submit a Transportation Mitigation Fee of $75.00 per average daily trip (18 units x 6.47 average daily trips/unit = 116.46, 116.46 average daily trips x $75.00 = $8,734.50). This fee shall be submitted prior to the issuance of building permits. The applicant shall submit a construction plan indicating haul rote and hours, construction hours and a traffic control plan for approval prior to any permit being issued. Haul hours shall be limited to 8:30 AM to 3:30 PM unless approved in advance by the Development Services Division. Policy Nexus: Mining, Excavation, and Grading Ordinance, Transportation Mitigation Fee Resolution, Environmental Ordinance (SEPA) (6) Community Services Impacts: The proposed 18 unit residential development will increase the need for the park and recreation services that are offered by the City of Renton. To mitigate the impacts of this development that City has adopted a Parks Mitigation Fee of $354.51 per unit. The mitigation fee for this project is $6.381.18 (18 units x $354.51 = $6381.18). Mitigation Measures: The applicant shall submit the Parks Mitigation Fee of $354.51 per unit (18 units x $354.51 = $6,381.18) prior to the issuance of building permits. Policy Nexus: Parks Mitigation Fee, Environmental Ordinance (SEPA) (7) Noise Impacts: The project site is located adjacent to existing multi-family residential dwelling units. Construction noise can generate an impact on neighbors unless it is limited to the hours of normal activity in a residential neighborhood. City staff recommend that the construction hours be limited to 7:00 AM to 7:00 PM Monday through Friday, Saturdays as arranged with the City but no hours in excess of the weekday hours and no work on Sundays.

FAMILY HOUSING LUA-97-088,SA,ECF REPORT AND DECISION OFJULY 28,1997 Page 7 of 12 POLICE DEPARTMENT 1. Theft from construction sites is one of the most common reported crimes in the city. To protect materials and equipment it is recommended that all materials and tools be locked up when not in use. The site will need security lighting and should also be completely fenced in with portable chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area is private property. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. 2. Codes access as entry to each building is recommended to prevent trespassing of individuals who have no right to be on the property. Each unit should have solid core doors, preferably metal or metal over solid wood with peep holes and heavy-duty dead bolt locks. The bolts need to be at least 1-1/2" in length when extended and installed with 3"wood screws. 3. Sliding windows, including the glass patio doors, will need additional locks; these locks will need to secure the windows from being pried out of the frames vertically. This means the locks will need to be placed into the top or bottom of the frames, in addition to any lock that limits horizontal movement. (This applies especially to the bottom floor windows that are hidden from view on the rear side of each building.) 4. Alarm systems are recommended for each unit. The stairways at the complex should be constructed of lattice or metal railing so visibility is possible through the stairway. There should not be any solid walls in any stairway that would serve to limit the visibility up and down the stairs and provide a place for a criminal to hide while waiting for a homeowner to return home. In additional, the balcony walls also need to be made of either metal or wood lattice or railing - no solid walls for the same purpose. 5. Extra security lighting needs to be installed in the parking lots, along the sidewalks, in the stairways, and between the buildings. Measures should also be taken to provide additional lighting for the common trash dumping site. Since this is located away from the complex itself, proper lighting should be provided to assist in making the area safer for the residents. Each unit should have their individual unit numbers listed clearly, with the number at least 6" in height of a color that contrasts with the color of the building and placed under a light. This will aid police or medics who respond to a call in finding the unit they need to go to. 6. Landscaping around the exterior of the property should not be too dense or high. It is important to allow visibility. Too much landscaping will give the property the look of a fortress and make the residents feel isolated, and could also possibly give a burglary sufficient coverage to break into a unit. FIRE DEPARTMENT 1. The preliminary fire flow is 2,000 gpm. Two fire hydrants are required. One fire hydrant is required within 150 feet of the structure and one fire hydrant is required within 300 feet of the structure. 2. An approved fire sprinkler system is required within Building 5. 3. An approved fire alarm system is required to be installed throughout all five buildings.

Proposed building height is 36 feet (tallest), for a total elevation of 405 feet above sea level. The site is located within the Airport Horizontal Surface, that has an elevation of 179 feet above sea level. A Notice of Proposed Construction shall be submitted to the FAA for review prior to the issuance of building permits, and the applicant will need to comply with any restrictions established by the FAA. Issuance/acceptence of a building permit constitutues acknowledgement that the land use is compatible with the operation of the airport and that the site is subject to overflight by low flying aircraft 24-hours per day.

FAMILY HOUSING LUA-97-088,SA,ECF REPORT AND DECISION OF JULY 28, 1997 Page 9 of 12 C. Consistency with Site Plan Criteria In reviewing the proposal with respect to the site Plan Approval Criteria set forth in Section 4-31- 33(D) of the Site Plan Ordinance, the following issues have been identified by City Departmental Reviewers and Divisional Reviewers: CRITERIA: 1. Conformance with the comprehensive plan, its elements and policies; The project site is designated as Center Suburban (CS) on the Land Use Element Map of the Comprehensive Plan. Centers are intended to be an intense, mixed use urban places that are pedestrian oriented and provide a community focus for surrounding neighborhoods. The proposed project is consistent with goals and policies of the Comprehensive Plan. Goal 5: Develop a system of facilities which meet the public and quasi-public service needs of present and future Renton Residents. The proposed project will increase the amount of housing available within the City of Renton that have low to moderate income levels. Policy LU-97: Encourage multi-story office, commercial, and multi-family uses. The proposed use will increase the amount of multi-family housing in this area that is available to families with low to moderate income levels. Policy LU-123: In order to achieve a balanced mix, multi-family uses are intended to be integrated into the Centers. Residential density should be 10-20 dwelling units per acre. New residential only structures may be limited in order to encourage a 50% commercial office mix within the Center. The proposed project will a density of 19.8 dwelling units per acre. This density is within the acceptable range for this area. The project location would discourage its' use for commercial activities in that it is setback from the main roads in the area and a business located in this area would be difficult for someone to find. 2. Conformance with existing x sting land use regulations; The applicant requested a waiver from the parking standards in order to provide 30 parking spaces on the site instead of the required 32 parking stalls. This waiver was granted by the Department Administrator as the families that will be living in these units traditionally really more heavily on public transportation and own fewer vehicles than higher income families. The subject property is designated as Center Suburban (CS) on the City of Renton Zoning Map. The proposed development is consistent with the design standards of the CS zone. 3. Mitigation of impacts to surrounding properties and uses; The applicant has provided a landscape plan that is acceptable for the proposed project. The landscaping will act as a buffer between the existing development and the proposed project. The applicant will also be installing a water quality system that will remove potential pollutants from the surface water prior to the release of the storm water into the City's storm system. Although the proposed project provides a density of approximately 20 dwelling units to the acre, the design of the buildings, pitched roofs and siding materials, will give them an appearance of larger single family homes. 4. Mitigation of impacts of the proposed site plan to the site; The applicant will be grading and landscaping the project site as part of the development of this site. This work will stabilize the site and provide a good foundation for the proposed structures. A small play area is designed into the project so that younger children will not have to leave the project to find room to play games. The applicant will need to provide a minimum of a ten foot separation between the proposed buildings. The roadway on the site plan is not a dedicated public street. The applicant will need to provide emergency access and utility easements to the City of Renton to ensure the City's ability to access the site in the event of an emergency and be able to access the utility mains for this project.

Conservation of area-wide property values; The development and maintenance of the proposed project will help to conserve area-wide property values through the development of a vacant piece of property. 6. Safety and efficiency of vehicle and pedestrian circulation; A sidewalk system will be provided for the safe movement of pedestrian within the subject property. This walkway system will be connected into the City's sidewalk system on the adjacent streets. 7. Provision of adequate light and air; The buildings are well layed out on the subject property. Adequate sunlight will be able to reach the windows of the proposed residential units. Air will be able to circulate between and around each of the proposed buildings. 8. Mitigation of noise, odors and other harmful or unhealthy conditions; No noise, odors, harmful conditions or unhealthy conditions are anticipated with the proposed project. Existing City Codes will be able to address anything that may develop. 9. Availability of public services and facilities to accommodate the proposed use;and Adequate services are available to accommodate the proposed project. The applicant will need to provide the connections to City services. 10. Prevention of neighborhood deterioration and blight.

Theft from construction sites is one of the most common reported crimes in the city. To protect. , , materials and equipment it is recommended that all:materials and tools be locked up when not in use. The site will need security lighting and should also be completely fenced in with portable chain- link fencing. The fence will provide both a physical and psychological barrier to any prospective thief . and will demonstrate that this area is private property. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" ' • : throw when bolted: Glass windows in the trailer should be shatter-resistant •." ' '. 2. Codes access as entry to each building is recommended to prevent trespassing of individuals who have no right to be on the Property. Each unit should have solid core doors, preferably metal or metal over solid wood with peep holes and heavy-duty dead bolt locks The bolts need to be at least 1-1/2"in length when extended and installed With 3",wood screws. , . 3. Sliding windows, including the glass patio doors,will need additional locks,these locks will need to secure the windows from being pried out of the frames vertically: This means the locks will need to ., be placed into the top or bottom of the frames, in addition to any lock that limits horizontal 1 movement.. (This applies especially to the bottomindows that are hidden from view on the: floor w , rear side of each building) 4. Alarm Systems are recommended for each Unit. The stairways at the complex should be constructed 11 of lattice or metal railing so visibility is possible through the stairway. There should not be any.solid walls in any stairway that would serve to limit the visibility up and down the stairs and provide a place for a criminal to hide while waiting for a homeowner to return home. In additional,the balcony walls also need to be made Of either metal or wood lattice or railing-no solid walls for the same purpose. • , . 5. Extra security lighting needs-to be installed in the parking lots, along the sidewalks, in the stairways, and between the buildings. Measures should also be taken to provide additional lighting for the common trash dumping site. Since this is located away from the complex itself, proper lighting I should be provided to assist in making the area safer for the residents. Each unit should have their individual unit numbers listed clearly,with the number at least 6"in height of a color that contrasts with the color of the building and placed under a light This will aid police or medics who respond to a call in finding the unit they need to go to. • • . :- • , . . ' 6. Landscaping around the exterior of the property should not be too dense or high. It is important to allow Visibility. Too much landscaping will give the property the look of a fortress and make the ., . , , : •residents feel isolated, and could also possibly give a burglary sufficient coverage to break into a unit , .. . . . . y _ Jefferson Avenue Family Housing LUA-97-088,SA,ECF Advisory Notes(Continued) Page 3 FIRE DEPARTMENT 1.

A fee worksheet is attached for your use.However,it is recommended to call 235-2631 to verify the fees as generated by the permit system prior to issuing a check. POLICE DEPARTMENT 1. Theft from construction sites is one of the most common reported crimes in the city. To protect materials and equipment it is recommended that all materials and tools be locked up when not in use. The site will need security lighting and should also be completely fenced in with portable chain- link fencing. The fence will provide both a physical and psychological barrier to any prospective thief and will demonstrate that this area isprivate property. Construction trailers should be kept locked when not in use, and should also have a heavy-duty deadbolt installed with no less then a 1-1/2" throw when bolted. Glass windows in the trailer should be shatter-resistant. 2. Codes access as entry to each building is recommended to prevent trespassing of individuals who have no right to be on the property. Each unit should have solid core doors, preferably metal or metal over solid wood with peep holes and heavy-duty dead bolt locks. The bolts need to be at least 1-1/2" in length when extended and installed with 3"wood screws. 3. Sliding windows, including the glass patio doors,will need additional locks;these locks will need to secure the windows from being pried out of the frames vertically. This means the locks will need to be placed into the top or bottom of the frames, in addition to any lock that limits horizontal movement. (This applies especially to the bottom floor windows that are hidden from view on the rear side of each building.) 4. Alarm systems are recommended for each unit. The stairways at the complex should be constructed of lattice or metal railing so visibility is possible through the stairway. There should not be any solid walls in any stairway that would serve to limit the visibility up and down the stairs and provide a place for a criminal to hide while waiting for a homeowner to return home. In additional,the balcony walls also need to be made of either metal or wood lattice or railing- no solid walls for the same purpose. 5. Extra security lighting needs to be installed in the parking lots, along the sidewalks, in the stairways, and between the buildings. Measures should also be taken to provide additional lighting for the common trash dumping site. Since this is located away from the complex itself, proper lighting should be provided to assist in making the area safer for the residents. Each unit should have their individual unit numbers listed clearly,with the number at least 6" in height of a color that contrasts with the color of the building and placed under a light. This will aid police or medics who respond to a call in finding the unit they need to go to. 6. Landscaping around the exterior of the property should not be too dense or high. It is important to allow visibility. Too much landscaping will give the property the look of a fortress and make the residents feel isolated, and could also possibly give a burglary sufficient coverage to break into a unit. . ' Jefferson Avenue Family Housing LUA-97-088,SA,ECF Advisory Notes(Continued) Page 3 FIRE DEPARTMENT 1. The preliminary fire flow is 2,000 gpm. Two fire hydrants are required. One fire hydrant is required within 150 feet of the structure and one fire hydrant is required within 300 feet of the structure. 2. An approved fire sprinkler system is required within Building 5. 3. An approved fire alarm system is required to be installed throughout all five buildings. AIRPORT MANAGER 1. The ground level at the proposed site is 369 feet above sea level.

Purcell , Vice President of Archdiocesan Housing Authority General Partner of CCS/Renton Housing Limited Partnership Date: II 7. Project Narrative Jefferson Ave. Family Housing Summary: The Archdiocesan Housing Authority(AHA) and Catholic Community Services (CCS)propose to develop and manage 18 units of affordable family housing for low-income and formerly homeless families at 1000 Jefferson Avenue NE. Ten of the units will serve formerly homeless families with incomes between 0%-30% of median and eight will serve families with incomes between 0%-50%. The owner is the CCS/Renton Housing Limited Partnership, of which AHA is the general partner. Site Information: The property is an irregularly shaped lot with an area of 39,559 square feet. The property is bordered on all sides by private property, except that Jefferson Avenue NE extends to the property, and the property includes abandoned portions of this street. The site is approximately 215 feet long on the north border, 269 feet long on the east, 128 feet wide on the south, and 291 feet long on the irregularly-shaped west. The site is currently bare land with no improvements. City Approvals Requested: None,beyond the previous approved reduction of the parking requirements to 30 spaces. Special Site Features: The site has a steep slope on the east side (approximate maximum slope of 40%),which we plan to regrade and support with a retaining wall and building foundations. Proposed Use: We propose to construct 18 units (4 two-bedrooms, 14 three- bedrooms) and a common room in five buildings. The total square footage of the construction is approximately 19,571 square feet. The maximum height is approximately 35.6 feet. The total lot coverage (including all impervious surfaces) is approximately 23,472 square feet or approximately 59.3%. There will be 30 parking spaces on site. Access will be from Index Avenue,with egress on Jefferson Avenue. CONSTRUCTION MITIGATION DESCRIPTION For the Proposed Development at 1000 Jefferson Avenue NE Renton,Washington • • ' Proposed construction,dates: September, 1997— September, 1998 • Hours of operation: 7:30am—6pm on non-holiday weekdays • Proposed hauling/transportation routes: Site has direct arterial access via Sunset Blvd. SE to Highway 405 and Interstate 5. Materials will not need to be transported on residential streets. • Measures to be taken to minimize dust, traffic, mud, noise, etc.: The Civil Engineer will design an erosion control plan with check dams and filter fabric at the perimeter of the site, as required, in order to minimize the impact due to construction on the City's storm drain system. All other typical preventative measures, such as wetting the site and construction debris when dusty and keeping the street clean of construction debris, will be taken to ensure a construction site respectful of neighboring properties., :. CIT'l -OF RENTON Planning/Building/Public Works Department —� 7 Jesse Tanner,Mayor Gregg Zimmerman P.E.,Administrator March 12, 1997 Mr. Mike Moedritzer Tonkin/Hoyne/Lokan 204 First Avenue South I Seattle, WA 98104 Subject: JEFFERSON AVENUE FAMILY HOUSING REQUEST FOR A DEVIATION OF THE PARKING AND LOADING ORDINANCE STANDARDS Dear Mr. Moedritzer: I received and reviewed your March 11, 1997 request for reconsideration and approval for a deviation in the parking standards established in the City of Renton Parking and Loading code, as amended by Ordinance No. 4517. Reference made to the code in the following evaluation shall be taken to denote the City of Renton Parking and Loading Code. BACKGROUND A project has been proposed to develop multi-family housing at 1000 Jefferson Avenue NE. The proponent has requested a deviation of the parking standards to allow less parking than is required by the Parking and Loading Ordinance. Section 4-14-8A1c. of the Parking and Loading Ordinance requires 1.5 parking spaces per dwelling unit and Section 4-14-8A1d. requires one guest parking space for every four dwelling units for a total of 1.75 spaces per dwelling unit. The proposed plan for this project would require 32 spaces, however the proponent is proposing only 30 spaces, or 1.67 spaces per dwelling unit. SUMMARY OF REQUEST The proponent is requesting a deviation from the standards of the Parking and Loading Ordinance in order to develop multi-family housing at the desired density. The proposed housing will be built for low income families. The proponent contends that low-income residents living in this type of project will not own as many cars and will have a higher rate of transit usage, therefore, there is less of a need for parking as compared to higher income apartment projects. The proponent also indicates that the proposed project will be situated close to service oriented commercial uses that would promote pedestrian and bicycle use and that the projects will be well served by Metro. FINDINGS 1. Parking and Loading Section 4-14-1.C.1.a states: Approval for deviation from standards: Whenever there are practical difficulties in carrying out the provisions of this chapter, the Planning/Building/Public Works Administrator may grant in writing modifications to the standards for individual cases, provided that such modifications: Conforms to the intent and purpose of the Code; and can be shown to be justified and required for the use and the situation intended; and will not create adverse impacts to other property(ies) in the vicinity; and will be made prior to detailed' engineering and design. 2. The proposed site plans are not able to accommodate the required parking. The proponent claims that the proposed project will have less of a demand for parking than higher income projects. 200 Mill Avenue South - Renton, Washington 98055 • Jefferson Avenue Family Housing Administrative Decision 3/12/97 Page 2 3. The proposed 18 unit project located on Jefferson Avenue NE would provide 2 less spaces than what is required by the code. 4. The request has been made prior to submittal of detailed engineering and design drawings. The conditions stated:in the Code for approval for deviation from standards have been met. DISCUSSION One of the important p rposes of the Parking and Loading Ordinance is to require proposed development projects to provide sufficient on-site parking spaces so as not to create undue demands on a limited supply of street parking spaces. It is intended that projects be designed such that the criteria for on-site parking can be met. Options for meeting these criteria can include creative layout of parking stalls or adjustments in dwelling unit counts. Introduction of vehicles using street parking or other off-site parking options due to provision of insufficient on-site parking spaces can create adverse impacts to other property in the neighborhood and does not conform to the intent and purpose of the Code. The applicant has requested and received reconsideration of the City's earlier denial of a Parking and Loading Ordinance deviation request to install 26 parking spaces at this site. The applicant has modified the site plan in order to accommodate 30 parking spaces, an increase of 4 spaces over the previous application, but 2 spaces short of full compliance with the City Code. In,addition the applicant has submitted anecdotal information indicating that the tenants of such transitional housing projects generally utilize less parking spaces than typical multi family residence tenants. Information from the American Planning Association indicates" that several cities recognize a lower need for parking spaces for subsidized housing tenants (Bay City Michigan requires one space for each two dwelling units, and Gainesville Florida requires one space per dwelling unit). Considering that the 4 additional spaces proposed in the revised site plan brings the project to within two spaces of the Code requirement, and that there is anecdotal information supporting the contention that transitional housing tenants require less parking spaces than traditional multi family residence tenants, it appears to the reviewer that the intent of the Parking and Loading Ordinance is being met by this revised proposal. DECISION The request for a deviation from standards to provide fewer on-site parking.spaces (1.67 spaces per dwelling unit) for the Jefferson Avenue Family Housing Project than is called for in the Parking and Loading Ordinance (1.75 spaces per dwelling unit) is hereby approved.

The development includes a drainage basin area of 0.93 acre. Included in this section of the report is a vicinity map and layout of the tax parcel in question. Proposed stormwater controls on-site include a biofiltration swale for water quality and a detention VAi.LLT•for water quantity control. The biofiltration swale is designed per King County guidelines and is placed downstream of the detention system in order to minimize the peak flow rates to the swale. 9- ve • is [r��b k re sv ' . ardle AV, o, N 14 • .::' �' ;*:;:;:� :.::�::- die' w O•z to Lake A S 1:4..:.;.x.:: `�'r:.;:::t::••••••:tic x CI1 Perri •O • 9.:.z z.1 ... 1 g 1).e... m ro g, N1,,f. m .Shattuck' <Ave c • •.-r : :.:•'' •H - , S w .t.'

PRELIMINARY CONDITIONS SUMMARY Calculations for detention sizing and biofitration swale sizing are per King County guidelines. Calculations for the detention system are located in the "Retention/Detention Analysis and Design" section of this report. Calculations for the biofiltration swale are located in the "Conveyance Systems Analysis and Design" section of this report. A soils report for the subject site was prepared by GeoEngineers and is dated March 21, 1997. The findings in the report have been used to establish the hydrologic soil type and the curve numbers as shown in this section of the report. A portion of the soils report is included in the appendix for reference. Basin area maps have been prepared for pipe sizing as well as for detention sizing and are located in the respective sections of this report. • c7 S42S1.00 O o OF 126.230 63.900 @• 3 5 S89°45'45"E 6 S89°45'45"E (55 ' S> 7 Sj�SO 0022 00 O 2 o Parcel Boundary A= 40594.2 sq. feet ao irnn o0 (Q T C1 CDNN R. 175.000 co L.A.= 210.542 A= 68°55'56" T. 120.122 1 .110 11 S16°05'00"W 10 �3 SN 5 '0 01,1, 9 • N7g?-0 04"w 8 AA Yf1AP S #1A .

However, high CN areas should not be combined with low CN areas (unless the low CN areas are less than 15% of the subbasin). In this case, separate hydrographs should be generated and summed to form one hydrograph.

III. OFF-SITE ANALYSIS The site is located in the Lake Washington drainage basin. Drainage from the proposed development enters a 177.5 foot long 12-inch diameter, concrete storm drainage pipe in Index Avenue NE at 0.3 percent slope. Drainage then enters a concrete 12-inch pipe in NE 10th Street and flows approximately 305 feet northwesterly to Sunset Blvd at 2.4 percent slope. At this point drainage enters a 12-inch concrete pipe heading southwesterly in Sunset Blvd. The slope of this system is unknown but the average slope of Sunset Blvd. is 4-percent. Shortly after Sunset Blvd turns northwesterly(approximately 1,300 feet downstream of the site), the.12-inch culvert system turns southwest toward NE 9th Place (this turn follows the downstream contours). The average surface slope in this region is 20-percent. This is the end of the quarter mile downstream analysis. tIP \ t imp 4 20 ST NE 20 S .�..I N E 20 ST �Q, ^PP� 144—� o > CT Q a w w• Z "' NE'19 in "I- NE m L�K� a) z z u z _ NE 19 ST' m m c m Q P� <'� 18 ST c C /� c a �,o Q 2 NE 1�\- •w 17 PL Whi a .. \Wf"�JKI„��''t�� 'a Zta J E 15 ST 4os 16 ( T m 15PL o� N 7S NE17ST NE17ST 900 .J • r.. \ a'i ; w �' Ne�Q c :• � �� 1 c ci Q Z N d , > o 411/ �� a y m C RN .r . c i c •E 14 ST• w `�sa� I 0NE14 M P c MIelLEO Q> 2. ra Z Q�0' U • 2 �S.1.saL , '. �b > w ' ti a z > F o •-•- ... . ........ ... . - a NE '° Y - _ NE :I: ' to hi v ,' w C v , 1 LIT;Pc: .1 > .w 2 , Q Z -1 C 11 C / � F Park a • ¢ E 2 •� Z � � � NE 11 T `I . 1 ST 1 EXIT 5 0��� , I c�Q � NE 'i0 PL dL SS C'j :o, '� • 1a THE BOEING COMPANY / o E 10 PL :11r_INDUSTRIAL AREA y© s:;i►� _ 5 1E NE 10 ST x 10 ST Al ArrIPIPPLIew.g& a� • 10 ST Z �Li �, �S w NE 9 ST ' 0 1 .

RETENTION/DETENTION ANALYSIS AND DESIGN Calculations have been prepared for a stormwater detention tank sized for the 2, 10, and 100 year/24 hour SBUH storm. In order to prepare the calculations, the "WaterWorks" hydrologic software program was used. The results show that the designed detention system provides storage on an average volume of 3,400 cubic feet per acre. Calculations supporting these conclusions are found on the following pages. •.1 1%5 KING COUNTY, WASHINGTON, SURFACE WATER DESIGNMANUAL FIGURE 3.S.1C 2-YEAR 24-HOUR ISOPLUVIALS ' OW 1 �Ic:.-'-- i 0 ofti ; . *--- --- ..., Itip-dnirAfk::Av.Ailig 40 . 4iiiki@ft 4,ii..—.: lir.,0 os..........„siskyaipm-. ft.w_ ir FIR 11; 11 ilitrec 1#17141.It 41114714, i 10 I PV/At NV AV' • t,,Ntlik , e, /,‘. dgcrikrii iiiiimosts.,„ lk:‘,41,30„.\ Aa ........,,_....21_,...., •• is 1,......,,, .. ,- ___1, ap* itisammi ....7A-Ali i . jp Il...1 0 • }if i � Ailit414641411;i1411111111Pilltikill\thlilli41104e ,:vlij. ie wr. ifir► ..�,�., *.)

V. CONVEYANCE SYSTEMS ANALYSIS AND DESIGN The proposed biofiltration swale, and pipe system are analyzed using procedures outlined in the King County Surface water design manual. • The biofiltration swale is designed using the King County method for the 2 year/24 hour outflow rate from the detention system. The conveyance capacity of the swale is confirmed using the 25 year and 100 year storms. The biofiltration swale is shown to convey the 25 year storm with a minimum of 0.5 foot of freeboard while the 100 year storm does not overtop the:swale. The swale was sized to meet the minimum width requirement of 2-feet. The pipe system is sized using the 25 year rational method model. Calculations for the biofiltration swale and the pipe system are on the following pages. 7 Xt ,BUSH,ROED&HITCHINGS, JOB - 1 CIVIL ENGINEERS&LAND 5.; :TEYORS SHEET NO.

SPECIAL REPORTS AND STUDIES 1. A portion of the soils report is included in the appendix. • 45 VII. BASIN AND COMMUNITY PLANNING AREAS The site is located in the Renton highlands and is in the Lake Washingon basin. •.J Sys VIII. OTHER PERMITS (N.A.) • IX. EROSION/SEDIMENTATION CONTROL DESIGN The erosion control facilities designed include an interceptor swale, silt fence, and a rock construction entrance. A sediment trap is not utilized on this site for two reasons. First, the site is less than an acre. Second, the soils on-site are everett outwash type, and no surface sheet flows are expected due to the high infiltration rate of everett soils. Finally, installation of a sediment trap meeting the 3:1 sideslope requirements for King County is very difficult on this site: the site is too small given the layout of the five proposed houses. The erosion control strategy is to divert surface flows generated upstream around the site such that off-site flows are not introduced to freshly graded soils. In addition, silt fence located on the west side of the site will catch and treat any silt laden water which leaves the site. ; X.

REPORT GEOTECHNICAL ENGINEERING SERVICES PROPOSED JEFFERSON AVENUE FAMILY HOUSING 1000 JEFFERSON AVENUE NORTHEAST RENTON, WASHINGTON INTRODUCTION This report presents the results of our geotechnical engineering services for the proposed Jefferson Avenue Family Housing_project to be located at 1000 Jefferson Avenue Northeast in Renton, Washington. The property is a vacant lot located to the north and east of the Employment Security Department building, and south of the St. Vincent De Paul Store off of Sunset Boulevard Northeast. Jefferson Avenue Northeast currently deadends on the south side of the property. The preliminary site plan shows a continuation of Jefferson Avenue Northeast to intersect with Index Avenue Northeast on the northwest corner of the site. We understand that the proposed housing project will likely consist of four to five, two-story wood-frame buildings. Approximately 18 units will occupy the structures. Typical loads for structures of this type include maximum column loads less than about 50 kips and floor loads in the range of 50 to 75 psf(pounds per square foot). SCOPE The purpose of our geotechnical engineering services_is to evaluate subsurface soil and ground water conditions at the site as a basis for developing recommendations for site development, foundation design, and other aspects of project construction affected by subsurface conditions. Specifically, our services includes the following tasks: 1. Evaluate subsurface soil and ground water conditions at the site by excavating-eight test pits with a rubber-tired backhoe. Also, complete a reconnaissance of the steep slope • located on the eastern boundary_of the site. 2. Evaluate pertinent physical and engineering characteristics of the site soils from the results of laboratory tests_performed on samples obtained from the explorations. In particular, we completed moisture content tests. 3. Describe site conditions including detailed subsurface soil conditions encountered based on results of the field explorations and laboratory analysis. 4. Provide recommended criteria for site grading including stripping and excavation of any unsuitable soils or improvement of existing fill-on site, and imported fill gradation, placement and compaction. Also provided are structural fill requirements as needed for support of the buildings and pavements, and our evaluation of the effects of weather and/or construction equipment on the on-site soils and imported soils.

Provide recommendations.for pavement subgrade support and design sections for parking f and driveway areas. 11. Provide recommendations for surface and subsurface drainage systems to control ground water conditions should this be appropriate. • SITE CONDITIONS SURFACE CONDITIONS _ With the exception of the eastern boundary, the site is fairly level and vegetated with grass, scattered brush and a few deciduous trees. The site slopes up steeply to the east on the eastern boundary to the adjacent properties housing single family residences. The slope is thickly vegetated and has an overall relief ranging from 12 to 18 feet. The topographic survey prepared by Pac-Tech dated March 26,1993 indicates slope inclinations of 3H:1V (horizontal to vertical). No indications of instability were observed on the thickly vegetated slope face during our site reconnaissance on February 7, 1997. SUBSURFACE CONDITIONS We explored subsurface soil and ground water conditions by excavating eight test pits to depths ranging from 8 to 14.5 feet. Approximate locations of the explorations are shown in Figure 2. Descriptions of the field exploration and laboratory testing procedures and exploration logs are presented in the appendix. Subsurface conditions encountered in our explorations consist primarily of loose to dense sandy outwash soils. The soils become dense below a depth ranging from 4 to 10 feet. Interlayered stiff silt was encountered between a depth of 5 to 8 feet.in the test pits completed in the northeast'portion of the site (test pits TP-5 and TP-6). We also completed a slope reconnaissance and shallow excavations with hand tools on the eastern slope. We encountered dense silty sand with gravel and occasional cobbles (glacial till) within 1 foot of the existing ground surface on the slope face. GROUND WATER CONDITIONS Ground water seepage was observed in one of the test pit explorations (TP-1) at a depth of 12 feet below the existing ground surface. No seepage was observed in the remaining G e o E n g i n e e r s _ 2 • File No.2352-004-10-1130/032197 -o . explorations. We expect that surface water runoff permeates rapidly through the clean sands encountered at the site. The ground water level should be expected to fluctuate as a function of season, precipitation and other factors. CONCLUSIONS AND RECOM MENDATIONS GENERAL We conclude that the proposed buildings can be supported on shallow spread footings bearing on the existing(.tnedium dense native soils or on a zone.of structural fill. Support may be founded on the existing sandy soils encountered below the upper 6 to 12 inches of silty sand topsoil. The floor slabs can also be supported on the native soils following stripping of the upper silty sand topsoil. Any footings or slabs which need to be founded at a higher elevation than where the medium dense native soils are encountered should be supported on a zone of compacted - structural fill. A permanent wall will be required along the eastern border of the property where the site slopes up to the adjacent residences. We understand that the wall will likely be a rockery or a _ conventional concrete retaining wall. Recommendations for these walls and for temporary and permanent cut slopes are provided in detail in following sections. Portions of the surficial soils at the site consist of moisture-sensitive silty sand. Construction traffic on these soils will result in considerable disturbance during wet weather. The clean sandy soils underlying the silty sand soils are less sensitive to moisture and are typically workable during wet weather conditions. The following sections of this report provide more detailed recommendations for design and construction. SITE PREPARATION - • We recommend that the surficial organics and topsoil be stripped from all building and pavement areas. The depth of stripping should be sufficient to remove the major root structure of the weed and grass cover. With the exception of localized grubbing of root structures of trees and brush, the depth of stripping across the site will be on the order of 6 to 12 inches. The stripped and/or cut material should be wasted from the site or used in landscaping areas. Those areas which are stripped and are to receive fill should be proofrolled with heavy rubber-tired construction equipment if work is done during extended dry weather. Any soft, loose or otherwise unsuitable areas identified during proofrolling should be recompacted, if practical, or removed and replaced with structural fill as described subsequently. We recommend that proofrolling of the subgrade be observed by a representative from our firm to assess the adequacy of the subgrade conditions and to identify areas needing remedial work. If site preparation is performed during wet weather, stripping should be done using lightweight construction equipment. Trafficability at the site under wet conditions may be difficult in some areas and result in disturbance to exposed subgrade areas.

SITE CONDITIONS SURFACE CONDITIONS With the exception of the eastern boundary, the site is fairly level and vegetated with grass, scattered brush and a few deciduous trees. The site slopes up steeply to the east on the eastern boundary to the adjacent properties housing single family residences. The slope is thickly vegetated and has an overall relief ranging from 12 4o 18 feet. The topographic survey prepared by Pac-Tech dated March 26,1993 indicates slope inclinations of 3H:1V (horizontal to vertical). No indications of instability were observed on the thickly vegetated slope face during our site reconnaissance on February 7, 1997. SUBSURFACE CONDITIONS We explored subsurface soil and ground water conditions by excavating eight test pits to depths ranging from 8 to 14.5 feet. Approximate locations of the explorations are shown in Figure 2. Descriptions of the field exploration and laboratory testing procedures and exploration logs are presented in the appendix. Subsurface conditions encountered in our explorations consist primarily of loose to dense sandy outwash soils. The soils become dense below a depth ranging from 4 to 10 feet. Interlayered stiff silt was encountered between a depth of 5 to 8 feet in the test pits completed in the northeast portion of the site (test pits TP-5 and TP-6). We also completed a slope reconnaissance and shallow excavations with hand tools on the eastern slope. We encountered dense silty sand with gravel and occasional cobbles (glacial till) within 1 foot of the existing ground surface on the slope face. GROUND WATER CONDITIONS Ground water seepage was observed in one of the test pit explorations (TP-1) at a depth of 12 feet below the existing ground surface. No seepage was observed in the remaining G e o E n g i n e e r s 2 File No.2352-004-10-1130/032197 `› ' r explorations. We expect that surface water runoff permeates rapidly through the clean sands encountered at the site. The ground water level should be expected to fluctuate as a function of season, precipitation and other factors. CONCLUSIONS AND RECOMMENDATIONS GENERAL We conclude that the proposed buildings can be supported on shallow spread footings bearing on the existing medium dense native soils or on a zone of structural fill. Support may be founded on the existing sandy soils encountered below the upper 6 to 12 inches of silty sand topsoil. The floor slabs can also be supported on the native soils following stripping of the upper silty sand topsoil. Any footings or slabs which need to be founded at a higher elevation than where the medium dense native soils are encountered should be supported on a zone of compacted structural fill. A permanent wall will be required along the eastern border of the property where the site slopes up to the adjacent residences. We understand that the wall will likely be a rockery or a conventional concrete retaining wall. Recommendations for these walls and for temporary and permanent cut slopes are provided in detail in following sections. Portions of the surficial soils at the sit; consist of moisture-sensitive silty sand. Construction traffic on these soils will result in considerable disturbance during wet weather. The clean sandy soils underlying the silty sand soils are less sensitive to moisture and are typically workable during wet weather conditions. The following sections of this report provide more detailed recommendations for design and construction. SITE PREPARATION We recommend that the surficial organics and topsoil be stripped from all building and pavement areas. The depth of stripping should be sufficient to remove the major root structure of the weed and grass cover. With the exception of localized grubbing of root structures of trees and brush, the depth of stripping across the site will be on the order of 6 to 12 inches. The stripped and/or cut material should be wasted from the site or used in landscaping areas. Those areas which are stripped and are to receive fill should be proofrolled with heavy rubber-tired construction equipment if work is done during extended dry weather. Any soft, loose or otherwise unsuitable areas identified during proofrolling should be recompacted, if practical, or removed and replaced with structural fill as described subsequently. We recommend that proofrolling of the subgrade be observed by a representative from our firm to assess the adequacy of the subgrade conditions and to identify areas needing remedial work. If site preparation is performed during wet weather, stripping should be done using lightweight construction equipment. Trafficability at the site under wet conditions may be difficult in some areas and result in disturbance to exposed subgrade areas. We recommend the G e o E n g i n e e r s 3 File No.2352-004-10-1130/032197 suitability of the subgrade soils be visually evaluated by a representative from our firm. A layer of sand and gravel with less than 5 percent fines (material passing the U.S. No. 200 sieve), crushed rock or quarry spalls, possibly underlain with geotextile fabric, may be useful to stabilize soft areas for access during wet weather construction. EARTHWORK We recommend that all fill placed in the building and pavement areas be placed and compacted as structural fill. The structural pad beneath footings should consist of a minimum 2-foot thickness of compacted structural fill, or the native medium dense soils. As described in subsequent sections of this report, we recommend that floor slabs be underlain by a minimum thickness of 4 inches of capillary break material overlying the existing medium dense native soils or compacted structural fill. The existing native soils should be proofrolled or otherwise evaluated and recompacted as necessary prior to capillary break placement. During dry weather, structural fill other than the capillary break material and the subbase subsequently recommended for the pavement section, can consist of granular material with less than 30 percent fines, providing that the fines are well mixed throughout the soil and are not present as clumps. The maximum particle size should be limited to 6 inches for general site grading and the moisture content should be near 4he optimum moisture content required for compaction. We should be provided samples of any proposed borrow material for evaluation prior to beginning earthwork. The pavement subbase and the capillary break material should consist of a well-graded, free-draining coarse sand and gravel free of organic matter and debris. The coarse sand and gravel fill should contain less than 5 percent fines by weight relative to the fraction passing the 3/4-inch sieve. If the fill is placed during wet weather, we recommend that all import fill meet this free-draining criteria. All structural fill should be compacted to at least 95 percent of its laboratory maximum dry density as determined by the ASTM D-1557 test procedure. The fill should be placed in horizontal lifts not exceeding 10 inches in loose thickness. Each lift must be thoroughly and uniformly compacted. TEMPORARY AND PERMANENT CUT SLOPES For planning purposes, we suggest temporary cut slopes of 1H:1V(horizontal to vertical) in the medium dense sandy soils encountered at the site. Where dense glacial till soils are encountered, the temporary slope inclination may be steepened to 0.5H:1V. These inclinations may have to be modified by the contractor if localized sloughing occurs. The following guidelines should also be considered to protect temporary slopes at the site: • No traffic, construction equipment, stockpiles or building supplies should be allowed at the top of cut slopes within a distance of at least 10 feet from the top of the cut. • Exposed soil along the slope should be protected from surface erosion using waterproof tarps or visqueen. G e o E n g i n e e r s 4 File No.2352-004-10-1130/032197 • Construction activities should be scheduled so that the length of time temporary cuts are left open is minimized. • Erosion control measures should be constructed as appropriate such that runoff from the site is minimized. • The general conditions of the slopes should be observed periodically by a geotechnical engineer to identify potential problems. Since the contractor has control of the construction operations, he should be made responsible for the stability of cut slopes, as well as the safety of the excavations. All shoring and temporary slopes must conform to applicable local, state and federal safety regulations. We recommend permanent cut slopes in the dense glacial till be inclined no steeper than 1' H:1V. Permanent cut slopes in all other soils as well as permanent fill slopes should be inclined no steeper than 2H:1V. CONVENTIONAL RETAINING WALLS Moderate cuts up to about 10 feet in height will be required along the east property boundary. Conventional concrete retaining walls or rockeries could be constructed in this area. Guidelines for rockery construction are provided in Vie next section. Cantilevered retaining walls should be designed for lateral pressures based on an (active) equivalent fluid density of 35 pcf (pounds per cubic foot) if the ground surface behind the wall is level for a distance of two times the wall height. This value should be increased to 55 pcf for the condition where a 2H:1V backslope is designed above the wall. Any appropriate surcharges should be added to these lateral pressures. The equivalent fluid density values applies to fill behind the walls that is placed and compacted as recommended previously with the exception that the MDD (maximum dry density) should be limited to a maximum of 92 percent to prevent overstressing the wall. It also assumes a free-draining condition behind the wall. This can be accomplished by placing a minimum 18-inch-wide zone of sand and gravel containing less than 5 percent fines against the wall: A drainpipe should be placed at the base of the footing to remove any water in this zone of sand and gravel or weep holes can be used if the seepage can be routed to a suitable discharge. We recommend that the footing drain be sloped to drain by gravity to the storm drainage system or other suitable discharge. The allowable passive resistance recommended in a following section"Lateral Resistance" is also applicable to retaining wall design. ROCKERIES We understand that a rockery may be considered for cuts along the eastern property boundary of the site. The primary purpose of a rockery is to protect the slope face from erosion and ravelling, while providing limited soil retention. Rockeries can be constructed in both cut G e o E- n g i n e e r s 5 File No.2352-004-10-1130/032197 and fill areas. Generally, in cut areas where dense native soils are exposed, rockeries may be up to 10 feet high. Rockeries greater than 4 feet high should not be used in fill areas without a specific geotechnical evaluation. Rockeries should be installed by a qualified contractor experienced in rockery construction. The construction should be monitored by a soils engineer. We recommend that rockeries be designed and constructed in accordance with the most recent version of the rockery guidelines prepared by the Association of Rockery Contractors. Figure 3 provides a typical schematic of geotechnical recommendations for rockery design. SHALLOW FOUNDATION SUPPORT Footings supported as described previously in the "Earthwork" section of this report can be designed for an allowable soil bearing pressure of up to 2,500 psf for dead plus long-term live loads. This value may be increased by one-third when considering earthquake or wind loads. All exterior footings should be founded at least 18 inches below the lowest adjacent finished grade, while interior footings can be founded a minimum of 12 inches below top of slab. We recommend minimum footing widths of 18 inches and 2 feet for continuous and isolated column footings, respectively. We estimate postconstruction foundation seqlements on the order of 1/2 inch or less for footings designed and constructed as recommended above. We recommend that the structure be designed to tolerate at least 1/2 inch of differential settlement between adjacent column footings to allow for any variability in subsurface conditions. Approximately 75 percent of the settlement is expected to occur within about two weeks of load application. FLOOR SLAB SUPPORT A structural fill pad at least 18 inches thick will provide satisfactory subbase support for floor slabs. If site grades are not raised sufficiently to place the recommended fill thicknesses, the native soils should be compacted to a minimum of 95 percent of the maximum dry density. Where the native soils cannot be compacted to the minimum standard, they should be excavated to allow placement of the 18-inch-thick structural fill pad. We recommend a 4-inch-thick base course consisting of a well-graded sand and gravel or crushed rock to provide uniform slab support. This base course layer, which will also serve as a capillary break, should have a maximum particle size of 3/4 inch and contain less than 5 percent by weight passing a U.S. No. 200 sieve. If the fill pad is constructed during wet weather conditions, the material specified for structural fill will provide satisfactory base course support; however, material greater than 3/4 inch in size should be excluded. No vapor barrier is expected to be necessary unless control of moisture in the slab area is critical (e.g., where an adhesive is used for tiled or carpeted floors). In that case, a vapor barrier consisting of polyethylene sheeting with bonded seams should be installed. In order to G e o E n g i nee r s 6 File No.2352-004-10-1130/032197 . maintain the integrity of the vapor barrier, it should be placed on a leveling course of sand (if the underlying base course consists of crushed rock) and be covered with a layer of sand to protect against damage by workers. We estimate that postconstruction settlements due to areal floor loads should not exceed about 1/2 inch. Differential settlements across the floor area should be less than 1/4 inch in 25 feet if relatively uniform areal loading conditions are maintained. LATERAL RESISTANCE The soil resistance available to resist lateral foundation loads is a function of the frictional resistance which can develop on the base of the footings (and slabs-on-grade) and the passive resistance which can develop on the face of the below-grade elements of the structure as they tend to move into the soil. Frictional resistance may be evaluated using 0.4 for the coefficient of base friction against footings and building slabs-on-grade. The allowable passive resistance on the face of subgrade walls and footings may be computed using an equivalent fluid density of 300 pcf (as a triangular distribution) if all soil extending out from the face of the foundation element for a distance at least equal to two and one- half times the height of the element consists of level, structural fill or medium dense native soils. This passive resistance may be increased to 400 psf.lif the adjacent soil consists of dense glacial till (extending out at least two and one-half times the height of the foundation element). The above coefficient of friction and passive equivalent fluid density values include a factor of safety of about 1.5. PAVEMENT RECOMMENDATIONS The pavement subgrade area should be prepared in accordance with the recommendations for site preparation. For the most part, the native sandy soils encountered below the surficial topsoil layer will provide suitable subbase for pavement support. Localized excavations may be necessary where wet, silty soils are encountered. In this case, we recommend a minimum 6-inch- thick subbase layer consisting of sand and gravel with less than 5 percent fines. We recommend that the pavement section in automobile parking areas consist of a minimum thickness of 2 inches of Class B asphalt concrete over a minimum thickness of 4 inches of crushed rock. The crushed rock should be similar to Washington State Standard Specification 9-03.9(3). We do not have specific traffic count data for the proposed extension of Jefferson Avenue Northeast for design of the pavement section. We expect fairly light traffic will utilize the street extension (on the order of 200 to 300 vehicles per day). For this condition, we recommend the pavement section consist of a thickness of 3 inches of Class B asphalt thickness overlying a thickness of 6 inches of crushed rock base course. G e o E n g i n e e r s 7 File No.2352-004-10-1130/032197 . The crushed rock base course and subbase should both be compacted to at least 95 percent of the MDD determined in accordance with ASTM D-1557. Backfill in utility trenches underlying paved areas should also be compacted in accordance with the recommendations for structural fill presented in this report. DRAINAGE CONSIDERATIONS We recommend that the roads and parking areas be sloped to drain away from the buildings such that surface runoff is collected and carried off the site. A perimeter footing drain is recommended unless the floor grade is raised more than 1 foot above the existing ground surface. Any footing or wall drains should be routed to a suitable discharge point, preferably to a storm sewer. Roof drains should also be separately routed to a suitable discharge point and should not be connected to any other subdrains.

Exploration locations were located by pacing from existing site features. Elevations were interpreted from the topographic drawing "Highlands Apartments Topographic Survey", by Pac-Tech Engineering, Inc. dated March 26, 1993. The test pits were excavated to depths of 8 to 14.5 feet on February 7, 1997. The explorations were continuously monitored by a geotechnical engineer from our firm who maintained detailed logs of the excavations and obtained representative samples of the soils encountered for further examination in our laboratory. The soils encountered were visually classified in accordance with the system shown in Figure A-1. The logs of the explorations are presented in Figures A-2 through A-5. The elevations indicated on the logs are based on interpolation of the topography on the topography map provided by you. The densities noted on the logs are based on probing the exposed soils with a 1/2-inch-diameter steel rod, the difficulty of digging and our experience and judgment. Observations of ground water conditions ware made as the explorations were performed. The ground water levels observed during excavating are presented on the logs. LABORATORY, TESTING All soil samples obtained were brought to our laboratory for further examination. Selected samples were tested to determine their moisture content. The results of the moisture content tests are provided on Figure A-6.

Field classification is based on visual examination of soil Dry- Absence of moisture, dusty, dry to the touch in general accordance with ASTM D2488-90. Moist- Damp, but no visible water 2. Soil classification using laboratory tests is based on ASTM D2487-90. Wet- Visible free water or saturated, usually soil is obtained from below water table 3. Descriptions of soil density or consistency are based on interpretation of blow count data,visual appearance of soils, and/or test data. • I a` lie SOIL CLASSIFICATION SYSTEM W Geo NO Engineers FIGURE A-1 LOG OF TEST PIT DEPTH BELOW SOIL GROUP GROUND SURFACE CLASSIFICATION (FEET) SYMBOL DESCRIPTION TEST PIT TP-1 Approximate ground surface elevation: 374 feet 0.0- 1.0 SM Dark brown silty fine sand with roots(loose,moist) 1.0- 5.0 SP Gray-brown fine to medium sand(loose to medium dense,moist) 5.0- 14.5 SM/SP Grayish brown silty fine to medium sand interlayered with gray-brown fine to medium sand(dense,moist) Grades with gravel and occasional cobbles at 13.0 feet Test pit completed at 14.5 feet on 02/07/97 Slight ground water seepage observed at 12.0 feet Moderate caving observed at 12.0 feet Disturbed soil samples obtained at 1.5,3.0,5.5 and 13.5 feet TEST PIT TP-2 Approximate grvund surface elevation: 369 feet 0.0- 1.0 SM Dark brown siltyfine to medium sand with organic matter (fine to coarse roots) g (loose,moist) 1.0- 10.0 SP Gray fine to medium sand with a trace of silt and occasional coarse gravel(medium dense,moist) Coarse roots observed at 9.5 feet Test pit completed at 10.0 feet on 02/07/97 No ground water seepage observed No caving observed Disturbed soil samples obtained at 2.5 and 7.5 feet THE DEPTHS ON THE TEST PIT LOGS,ALTHOUGH SHOWN TO 0.1 FOOT,ARE BASED ON AN AVERAGE OF MEASUREMENTS ACROSS THE TEST PIT AND SHOULD BE CONSIDERED ACCURATE TO 0.5 FOOT. p• LOG OF TEST PIT Geo., Engineers �/ FIGURE A-2 LOG OF TEST PIT DEPTH BELOW SOIL GROUP GROUND SURFACE CLASSIFICATION (FEET) SYMBOL DESCRIPTION TEST PIT TP-3 Approximate ground surface elevation: 374 feet 0.0- 1.0 SM Dark brown silty fine sand with organic matter(roots)(loose,moist) 1.0- 4.0 SP-SM Orangish brown and gray fine to medium sand with silt and occasional gravel (medium dense,moist) 4.0- 10.0 SP Brown and gray fine to medium sand(dense,moist) Grades with gravel and thin lenses of silty fine sand at 9.0 feet Test pit completed at 10.0 feet on 02/07/97 No ground water seepage observed No caving observed Disturbed soil samples obtained at 2.0 and 9.0 feet TEST PIT TP-4 Approximate ground surface elevation: 374 feet • 0.0- 2.0 SM Dark brown silty fine to medium sand with occasional coarse sand and gravel (medium dense,moist) 2.0- 5.5 SM Orange and gray silty fine to medium sand with occasional gravel(medium dense, moist) 5.5- 10.0 SP Gray fine to medium sand with gravel(medium dense to dense,moist) Test pit completed at 10.0 feet on 02/07/97 No ground water seepage observed No caving observed Disturbed soil samples obtained at 1.5,3.0,4.0 and 9.0 feet THE DEPTHS ON THE TEST PIT LOGS,ALTHOUGH SHOWN TO 0.1 FOOT,ARE BASED ON AN AVERAGE OF MEASUREMENTS ACROSS THE TEST PIT AND SHOULD BE CONSIDERED ACCURATE TO 0.5 FOOT.
