Page 2 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The Olympic View Water and Sewer District (District) has concluded that the existing Administration Office building located at 23725 Edmonds Way, Edmonds, Washington, no longer adequately meets the needs of the District and additional office space would better serve the District’s goals. The current facility is located within the Edmonds city limits. The original Administration Office was built 1972 and is in need of upgrades and modernizations. The Administration Office building would be constructed at the District’s th new site located on 228 Street SW within Snohomish County. The existing Administration Office building would be demolished and the site would be redeveloped to accommodate a new Equipment and Materials Center that would provide vehicle and miscellaneous indoor and outdoor storage, a small maintenance shop and a Vactor truck disposal area. The construction of the new Equipment and Materials Center would commence upon receipt of all th necessary permits and after construction is complete on the new Administration Office building at the 228 Street SW site. This would allow business to be conducted during the construction phase without displacing or crowding the District’s current offices. Construction on the Equipment and Materials Center is anticipated to be complete in 2011. The District Equipment and Materials Center would be considered a “Local Public Facility” and is allowed in the RM 1.5 (Multiple Residential) zone subject to approval of a Conditional Use Permit (CUP). A CUP was approved in 1992 by Snohomish County for the construction of the Operations Office and Equipment Storage building (County File No. ZA 9108257) and the site was annexed by the City of Edmonds in 1995. No permit activity has occurred since 1995; therefore, the District is seeking CUP approval from the City of Edmonds to reorganize the site and to allow for outdoor storage of materials. The District proposes to reorganize the Equipment and Materials Center at the existing Administration and Operations Center site. Located at 23725 Edmonds Way SW, the District-owned site is an irregular shaped parcel that is relatively flat with the exception of berms along the northern and eastern property lines. The eastern property line is occupied by an approximately 10-foot high concrete retaining wall, which would remain, and various sections of 6-foot high chain link fence that would be removed. The existing 7,600 square foot Vehicle and Equipment Storage building would also remain. The north and east property lines, the southern corner and an area of existing trees on the south western portion of the property lines would Figure 1Site Development Plan not be disturbed (see - ). A 6-foot high chain link fence is proposed south of the proposed site access, along the western portion of the property. Material storage bins approximately 6-feet high would abut the chain link fence and would continue around the southern tip of the property and run parallel to the existing 10-foot high concrete wall. The site currently contains two structures; one would be retained and one would be demolished. The site layout proposes to demolish the existing 1,426 square foot Administration and Operations building on the eastern portion of the 0.81 acre (35,400 square feet) site and to relocate the gasoline fuel tank and locate the generator in its place. As previously described, the functions of the Administration and Operations th building would be relocated to the 228 Street SW site within Snohomish County. The proposed Equipment and Materials Center would consist of the existing 2-story (7,600 square foot) structure, which would be used for vehicle storage for less frequently used vehicles, a small maintenance shop and miscellaneous interior storage, as well as open outdoor site storage, soil material storage bins, Vactor truck soil disposal, fuel storage and four parking stalls. The open yard storage would be used for piping, valves, trench boxes and other miscellaneous materials and soil material storage would be used for gravel, spoil Page 3 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. dirt, washed rock, asphalt, broken paving and clean, green yard waste. Soil bins would be located along Edmonds Way with 6-foot high concrete bin walls separating the storage areas from the street to create a visual barrier. The Vactor soil disposal bin would be located amongst the existing trees on the east side of the site. The new Equipment and Materials Center would consist of two separate contained Vactor decant stations: one for occasional use when sanitary sewer cleanout is needed, and one for the more frequent use with soft digging. Soft digging is a process of hydraulic excavation, normally for utility repair, where water is used instead of heavy equipment to avoid damage to any underground utilities. The District does not use the Vactor truck(s) to clean out catch basins or other parts of the storm water system. Each of the stations would accept the liquid from the Vactor truck and the solids suspended in the liquid. The liquid portion of the sanitary cleanout would pass directly into the sanitary sewer system. After dewatering, the resulting sanitary solids are estimated to be minimal. This material would be manually collected and taken directly to the City of Edmonds Waste Water Treatment Facility for disposal. The new open site storage area would be created between the bin storage and the existing 2-story building that is to be retained. The storage area would be paved and screened on the east side from the adjacent multi-family housing development by a landscape buffer of existing trees supplemented with new vegetation. The proposed development would remove the existing access points along Edmonds Way (SR-104) to a th new (single) access further north. The new site access would be approximately 245 feet north of 238 Street SW. The two existing access points would be removed. The new entry would reduce potential conflict points and a swing gate would be provided to allow secure vehicle access to and from the site. The new access would be a paved area that would include the open site storage area and an access drive approximately 34 feet wide to the existing vehicle and equipment storage building and the four parking stalls. An ADA accessible sidewalk would be installed in two sections approximately 39 feet and 52 feet long and 5 feet wide along Edmonds Way. These two sections would connect to the existing sidewalk. Landscaping is proposed along Edmonds Way, around the storage bins on the southeast side of the site and north of the access drive along the northwest property line. Existing trees would be retained on the southern tip of the property, an area between the bin storage and the open site storage area on the south side Figure 2 - Landscape of the site and on the east and north property lines that would not be disturbed (see Plan ). 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The proposed project would be located at 23725 Edmonds Way in Edmonds, Washington. The subject property is located within the southwest quarter of Section 31, Township 27 North, Range 4 East, W.M., which is within the city limits of Edmonds. The Snohomish County Tax Account Number for the subject Exhibit A - Legal DescriptionFigure 3 - Vicinity Map property is 00463300600100 (see and ). Page 4 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. Figure 3 – Vicinity Map The property is approximately 0.81 acres and is bordered on the north by a multi-family development and on the west by an adjacent commercial building. Adjacent property to the east is occupied by a multi- family development, and the south property line abuts Edmonds Way. EVALUATION FOR AGENCY USE ONLY B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site (underline one): flat , rolling, hilly, steep slopes, mountainous, other. The site topography of this site slopes gradually to the west. b. What is the steepest slope on the site (approximate percent slope)? Page 8 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY The steepest slope is approximately 5%. c.What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. According to the Natural Resources Conservation Service (NRCS) Soil Survey the site contains two soil types: Alderwood-Urban Land Complex (8-15 % slopes) and McKenna Gravelly Silt Loam (0-8% slopes). There are no prime agricultural lands within the project area. Both of these soil types are derived from glacial tills, with the finer McKenna typically found filling in former depressions and drainage ways in the more gravelly Alderwood-Urban Land Complex. McKenna soils are classified as poorly drained and may have water at or near the surface. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There are no indications of unstable soils or seismic activity on the site. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Approximately 185 cubic yards of cut and 250 cubic yards of fill would occur on the site. On-site grading would be primarily a result of the removal of existing paving and its replacement to matching grades, as well as the excavations needed for concrete bin footings and the Vactor decant station. Fill would be obtained from an off-site source (yet to be determined). f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There could be a short-term increase in the potential for on-site erosion where soils are exposed during site preparation and construction; however, the proposed project would comply with all applicable erosion control measures, including the use of silt fences around the site perimeter. After site construction there would be limited potential for erosion. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? With the proposed development and associated site improvements, approximately 66% of the 0.81-acre site would be covered by impervious surfaces. The existing equipment storage building would be approximately 0.13 acres of impervious surfaces on-site and the pavement and driveway areas would be 0.41 acres. This would comply with the maximum coverage area of 45% per Edmonds Municipal Code 16.30.030 because the structure on-site would makeup 16% of the impervious surface on-site. Page 9 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY The new impervious surface area would be approximately 5,930 square feet and the removed impervious surface area would be 5,175 square feet for a net impervious increase of 755 square feet. This would increase site’s impervious surface percentage by 2.2% as a result of this proposal. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Several measures are proposed to minimize erosion. During construction, silt fences would be erected along the northwest, south and half of southeast edges of the site to prevent sediment-laden stormwater from entering existing drainage facilities \[see Figure 4 - Temporary Erosion and Sediment Control and Demolition Plan (Plan)\] for additional details. The Plan would be in accordance with the Department of Ecology 1992 Stormwater Management Manual. After site construction, there would be limited potential for erosion. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors and industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Construction of the proposed project would result in temporary, localized increases in pollutant emissions from construction activities and equipment. For example, dust from excavation and grading would contribute to ambient concentrations of suspended particulate matter. Construction contractor(s) would have to comply with the Puget Sound Clean Air Agency’s (PSCAA) Regulation I, Section 9.15 requiring reasonable precautions to minimize dust emissions. Reasonable controls may include applying water or dust suppressants during dry weather, and vehicle washing and street cleaning to prevent dirt, mud and other debris deposits on paved roadways open to the public. The PSCAA, in connection with the Washington State Department of Ecology (Ecology), conducts air quality monitoring at several sites around Puget Sound. According to PSCAA’s 2006 Annual Report (the most recent available), air quality within the Puget Sound basin has been in compliance with State and Federal particulate air quality standards since 1988, and ozone and carbon monoxide standards since 1996. Emissions related to construction should be short-term and relatively minor. As a result, no significant air quality impacts would be expected from the redevelopment of the Equipment and Materials Center. Once the project is completed, main emissions sources would be from vehicles on the site and traffic on the adjacent road system. The type and levels of those emissions would be similar to existing levels. Page 10 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY Odors from the Vactor decant station are potentially more concentrated during the transfer process, but would not differ from ambient odors from existing storm drains. The liquid would enter the existing sewer system and be conveyed off-site. Solids would be taken off-site and disposed of at the City of Edmonds Waste Water Treatment Facility. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. There are no off-site emissions or odors that would affect the proposal. Land uses in the vicinity are primarily residential, commercial and roads. As a result, pollutants are mainly particulates (from wood stoves, fireplaces, outdoor burning, and roads) and ozone and carbon monoxide from vehicular traffic. Emissions from vehicles on nearby roads would not have an effect on the proposal. c. Proposed measures to reduce or control emissions or other impacts to air, if any: During construction, the contractor would be required to implement dust control measures during construction such as watering the ground as needed before and during clearing, demolition and grading activities to control dust particles, in accordance with PSCAA’s Regulation I, Section 9.15. Contractor(s) would be required to take all reasonable precautions to avoid or minimize fugitive dust emissions during construction. These precautions and control measures may include street cleaning to prevent dirt, mud and other debris deposits on paved roadways open to the public, and limiting the amount of time construction trucks are allowed to idle on-site. With such control measures in place, the potential from on-site air quality impacts is minimal. 3. WATER a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There are no surface water bodies on or in the immediate vicinity of the site. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Not applicable. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Page 12 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY No fill or dredge material would be placed in any surface water bodies or wetlands. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. The proposal does not require surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. The site does not lie within the 100-year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. There would be no direct discharge of waste materials to surface water. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No ground water would be withdrawn or discharged to groundwater. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material would be discharged into the ground from septic tanks or other sources. The Vactor decant station’s sanitary liquids, after dewatering, would be discharged directly into the sanitary sewer system and the limited amount of dewatered solids would be manually removed and disposed of off-site at the City of Edmonds Waste Water Treatment Facility. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. All future storm runoff, as is the case now, would be collected in roof drains and catch basins in the parking and circulation area, and conveyed to the existing detention vault. All stormwater enters the existing storm drainage system in Page 13 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY Edmonds Way, to the west. Since there would only be a net increase of 755 square feet of new impervious surface, no increased detention or water treatment is required by the City of Edmonds. 2) Could waste materials enter ground or surface waters? If so, generally describe. A minimal amount of oils, grease and other pollutants from the additional paved areas could potentially enter the ground or downstream surface waters through surface water runoff. Measures to prevent fluids leaking from machinery onto ground surfaces would be implemented during construction. The site is designed such that waste materials are not expected to enter ground or surface waters under final site conditions. d.Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Temporary erosion control measures would be in place during construction to prevent or minimize any increase potential for silty waters exiting the site and to reduce or prevent any increased erosion potential. The contractor is expected to employ additional erosion control Best Management Practices (BMPs) or provide additional erosion control measures as directed in the field to further reduce the potential for any adverse water impacts during construction. No adverse effects are expected during final conditions. 4. PLANTS a. Check or circle types of vegetation found on the site: deciduous tree: alder, big leaf maple, liquidambar, hazel, birch, and other ornamental trees evergreen tree: fir, cedar, pine shrubs: ornamental shrubs __ grass __ pasture __ crop or grain __ wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other: _________ __ water plants: water lily, eelgrass, milfoil, other: __________ other types of vegetation: ornamental groundcover b. What kind and amount of vegetation will be removed or altered? At the northwestern corner, where the new curb cut and entry drive would be located, three, 4-inch diameter, deciduous ornamental trees, several ornamental shrubs, and a portion of the existing ornamental hedge would be removed. c. List threatened or endangered species known to be on or near the site, if any: Page 14 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY No threatened or endangered plant species are known to be on or near the site. This was confirmed with the Department of Natural Resources Washington Natural Heritage Program database, which was updated as of October 31, 2007. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Plants removed in the northwestern corner would be replaced by one street tree, and ornamental shrubs and groundcover to match the new 10-foot wide landscape buffer, which would be planted along Edmonds Way to screen the concrete storage bins. This buffer would consist of Katsura trees (used as street trees), wild strawberry groundcover, and three types of ornamental shrubs: barberry, cotoneaster and viburnum. Other landscaping would include similar shrub plantings along the south and east sides of the Vactor decant station and storage bins close to the retaining wall on the Figure 2a – Landscape Plan eastern property line (see ). 5. ANIMALS a. Underline any birds and animals which have been observed on or near the site or are known to be on or near the site: birds: hawk, heron, eagle,songbirds, other: __________ mammals: deer, bear, elk, beaver, other: rodents fish: bass, salmon, trout, herring, shellfish, other: ________ b. List any threatened or endangered species known to be on or near the site. A query was made with the Washington Department of Fish and Wildlife on January 3, 2008, which found no known threatened or endangered animal species inhabiting or within 100 feet of the site. c. Is the site part of a migration route? If so, explain. The site is part of the Pacific Flyway, a migratory bird pathway that encompasses all of western Washington, which is used by a wide variety of songbirds, waterfowl and other species of birds. The specific level of use of this site by migrating birds is undetermined, but limited. Due to the extensive urban residential development patterns surrounding the site, it would most likely not be utilized by any mammalian species other than those more tolerant of urban development activities. d. Proposed measures to preserve or enhance wildlife, if any: The proposed landscaping plan includes deciduous trees, evergreen shrubs and groundcover. The proposed frontage landscaping and the retained landscaping areas Page 15 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY would enhance the site area. The landscape screens of deciduous trees and evergreen shrubs would provide cover for small animals, and serve as a visual screen for the adjacent properties. 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Electricity and natural gas are the predominant sources of energy to be used by the project. Electric power for the existing site would continue to be provided by Snohomish County Public Utility District No. 1 and natural gas would continue to be provided by Puget Sound Energy. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. This proposal would not affect the potential use of solar energy by adjacent properties. c. What kinds of energy conservation features are included in the plans of this proposal? List of other proposed measures to reduce or control energy impacts, if any: The requirements of the Washington State Energy Code and the International Building Code would be satisfied. Energy conserving materials are encouraged in all new construction. 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so describe. The existing 1,000 gallon above-ground gasoline storage tank would remain on-site, but be relocated across the parking lot to a new pad. No new risks of exposure, fire or explosion are expected. 1) Describe special emergency services that might be required. No special emergency services would be required. Ambulance/EMT services would occasionally be needed for normal industrial or construction site incidents/accidents. 2) Proposed measures to reduce or control environmental health hazards, if any: Page 16 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY Existing, on-site safety procedures are followed by the District, including regular training on the safe use and storage of petroleum products and solvents. The proposed relocation of the above ground storage tank for fuel would place it further from any buildings, thereby increasing safety at the site. The Vactor decant station’s sanitary chamber would be designed to ensure the sanitary liquid would pass directly into the sanitary sewer system, and the very limited amount of solids would be manually removed to the City of Edmonds Waste Water Treatment Facility. The Vactor decant station’s soft dig chamber would receive a slurry of water and dirt, and be no more hazardous than the average soils in the District. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, aircraft, other? Existing noise sources include both traffic and aircraft noise, but neither are expected to pose a significant adverse impact to the proposal. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Construction would be temporary in nature and after completion noise levels would be similar to existing conditions. Short-term impacts would result from the use of construction equipment during site development. Construction would occur primarily during the daylight hours, limited by code tothe hours of 7:00 a.m. to 6:00 p.m. on weekdays and 10:00 a.m. to 6:00 p.m. on Saturdays, excluding Sundays and federal holidays. Heavy equipment, hand tools and the transporting of construction equipment generate construction noise. At 200 feet from the construction, the Leq would be approximately: Activity Leq (in decibels) Clearing 71-72 Excavation 59-77 Types of Equipment Range of Noise Levels Bulldozer 65-84 Dump Truck 70-82 Paver 74-76 Generators 59-70 Compressors 62-69 Page 17 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY Long-term impacts would be those associated with the decrease in site users and change in uses, and are expected to be generated between the hours of 7:30 a.m. and 5:00 p.m. Less automobile traffic would be generated by the proposal, but there would be more truck noise and noise related to the delivery and removal of materials stored on-site and use of the Vactor decant station. The increase in noise would be typical of a commercial development of this size and would be considered minimal. Sound levels for various noise sources include: Sound Level at Noise Sources 100 feet (dBA) Automobile Starting 50-55 Closing Car Door 50-55 Loud Voices 50 Automobile/Truck Traffic 50 Noise levels from the completed project would remain consistent with existing levels, with occasional increases in volume and changes in character, as materials are brought to, or removed from the site and the Vactor decant station is used. 3) Proposed measures to reduce or control noise impacts, if any: Construction would be limited by Edmonds Municipal Code 5.30.110B to the hours of 7:00 a.m. to 6:00 p.m. on weekdays and 10:00 a.m. to 6:00 p.m. on Saturdays, excluding Sundays and federal holidays, thereby reducing impacts in the more sensitive evening and early morning hours. Noise levels from the completed project would remain consistent with existing levels, therefore no measures are proposed. 8. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? The site is the current location for the Olympic View Water and Sewer Administration and Operations Center. The property to the west contains a dental clinic, and the entire east side is bordered by multi-family condominiums. To the north is a multi-family development. The site is bordered on the south property line by Edmonds Way. b. Has the site been used for agriculture? If so, describe. The site has not been previously used for agriculture. c. Describe any structures on the site. On-site structures include a 1,426 square foot Administrative Office building, a 7,600 square foot Operations Office/garage building and a 1,000-gallon above- ground gasoline storage tank. Page 18 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY d. Will any structures be demolished? If so, what? The 1,426 square foot Administrative Office building would be demolished, and removed from the site. e. What is the current zoning classification of the site? The current zoning classification of the site is RM 1.5 (Multiple Residential). The proposed District facilities are considered a “Local Public Facility” and are allowed in the RM 1.5 zone as a Conditional Use Permit (CUP). f. What is the current comprehensive plan designation of the site? The current Comprehensive Plan designation for the site is Edmonds Way Corridor. g. If applicable, what is the current shoreline master program designation of the site? Not applicable. h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. No portions of the site have been classified as environmentally sensitive. i. Approximately how many people would reside or work in the completed project? There would be no residents at this site. The site would be only intermittently occupied by District staff as they come to trade vehicles or pick-up or deliver materials. j. Approximately how many people would the completed project displace? Approximately 12 employees would be relocated to the new Administration and Operations Center facility within Snohomish County. k. Proposed measures to avoid or reduce displacement impacts, if any: Employees displaced by the closing of the Administration and Operations Center would be relocated to the new facility located within Snohomish County. l. Proposed measures to ensure that the proposal is compatible with existing and projected land uses and plans, if any: The current District office and garage are considered a “Local Public Facility” and are allowed in the RM 1.5 zone subject to approval of a Conditional Use Permit (CUP). Because the current use of the site existed prior to its annexation into the Page 19 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY City of Edmonds, no CUP was obtained for the current operation. Currently the site is considered an existing non-conforming use by the City of Edmonds. The subject property lies within the Edmonds Way Corridor, which is a designated land use area within the City of Edmonds Adopted Comprehensive Plan (2006). Applicable goals for Public Facilities are as follows: B.1. Provide capital facility improvements in order to meet or exceed established level-of-service standards. The Olympic View Water and Sewer District (District) has concluded that the existing Administration and Operations Office at Edmonds Way no longer adequately meets the needs of the District and that additional office space would better serve the District’s goals. The District intends to relocate the Administrative and Operations offices to a new location in Snohomish County and the Edmonds Way site would be used for outdoor storage and equipment, and vehicle storage within the existing Equipment Storage building to be retained. In this way, the District would continue operations with room to accommodate their growing staff and equipment to provide or exceed the established level-of-service that Edmonds has come to expect. Concurrency Management A. Provide a system of concurrency management that will assure that the facilities needed to support city services are provided in a timely and coordinated manner according to the following policies: A.1. For all capital facilities, develop concurrency management systems to manage the provision of facilities and services in order to achieve and maintain level-of-service standards. To achieve current and future level of service standards, the District would have to expand its administrative and operations functions. Such an expansion would require more room than the Edmonds Way site alone can provide. Comprehensive Plan goals for the Edmonds Way Corridor are as follows: F.1. Use design review to encourage the shared or joint use of driveways and access points by development onto SR-104 in order to support the movement of traffic in a safe and efficient manner. Site access should not be provided from residential streets unless there is not feasible alternative. The relocation of the administrative and operational functions of the District from its current location on Edmonds Way would reduce the number of peak hour trips made to and from the building during the week. Although the site would still house equipment and automobiles, they would be used on an intermittent basis. The relocation of 12 staff members would result in a net reduction of -15.7 average daily trips with -2 AM peak hour \[7 to 9 a.m.\] trips (-2 inbound / 0 outbound) and -2 PM peak-hour \[4 to 6 p.m.\] trips (0 inbound / -2 outbound). The reduction of average daily trips would encourage safe traffic movement on SR-104 because fewer vehicles would be accessing the site on a daily basis. Page 20 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY F.4. Use design review to ensure that development provides a transition to adjacent residential neighborhoods. For uses in transitional areas adjacent to single family neighborhoods, use design techniques such as the modulation of facades, pitched roofs, stepped-down building heights, multiple buildings, and landscaping to provide designs compatible with single family development. Make use of natural topography to buffer incompatible development whenever possible. The proposed open storage bins would have 6-foot concrete walls to contain the bin materials. The back wall of the storage bins would run parallel to Edmonds Way to provide a buffer that would screen the materials and activities of the interior yard. In addition, there would be a 10-foot wide landscape buffer between the six feet tall concrete bin walls and the sidewalk on Edmonds Way, further softening the site from view. No conditional use permit may be approved unless all of the findings in section (20.05.010 Criteria and findings) can be made. A. That the proposed use is consistent with the comprehensive plan. The proposal is consistent with the previously referenced Comprehensive Plan policies as outlined above. B. Zoning Ordinance. That the proposed use, and its location, is consistent with the purposes of the zoning ordinance and the purposes of the zone district in which the use is to be located, and that the proposed use will meet all applicable requirements of the zoning ordinance. The proposed use would meet all setback, height and landscaping requirements of the zoning ordinance for the RM 1.5 (Multiple Residential) zone. Intensity of vehicular use would be reduced, with the relocation of 12 staff to the new facility within Snohomish County. C. Not Detrimental. That the use, as approved or conditionally approved, will not be significantly detrimental to the public health, safety and welfare, and to nearby private property or improvements unless the use is a public necessity. The proposed uses, most of which are already existing on the site, would not be significantly detrimental to public health, safety or welfare and would be compatible with the character, appearance, quality of development and physical characteristics of the site and surrounding area. The relocated gasoline tank would be farther away from neighboring buildings. Two existing curb cuts would be replaced and one new access is proposed to reduce potential conflict points and ensure proper sight distance for vehicles entering and leaving the site. The sanitary Vactor decant cells would be designed to minimize odor, with all liquids going immediately into the sanitary sewer system and the very limited amount of solids removed to the City of Edmonds Waste Water Treatment Facility. Landscaping is proposed along the site’s frontage on Edmonds Way to screen the use from view. Page 21 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY 9. HOUSING a. Approximately how many units would be provided, if any? No housing units would be provided with this proposal. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. No housing units would be eliminated as a result of this proposal. c. Proposed measures to reduce or control housing impacts, if any: None are proposed. 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The existing equipment storage building would be the only structure to remain on the site. It is below the 25 foot maximum height allowed in the RM 1.5 zone. b. What views in the immediate vicinity would be altered or obstructed? Residents in the existing condominiums (to the east) look down on the existing site, due to higher topography, and taller building. Their views would be altered in content as a result of the proposed reconfiguration of the site, but not obstructed. c. Proposed measures to reduce or control aesthetic impacts, if any: The proposed open storage bins would be screened from the east side from the adjacent multi-family housing development by a landscape buffer of existing trees and supplemented with new vegetation. In addition, there would be a 10-foot wide landscape buffer between the 6-foot tall concrete bin walls and the sidewalk on Edmonds Way, further softening the site view from the street. 11. LIGHT AND GLARE a. What type of light or glare will the proposal produce? What time of day would it mainly occur? The existing equipment storage building would continue to be lighted, but the light is primarily for internal use. Exterior building and site lighting would be used for safety and security purposes. Any additional lighting would be directed downward, away from adjacent properties, and would be planned to prevent glare off reflective surfaces and avoid spillage onto adjacent properties. Page 22 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY b. Could light or glare from the finished project be a safety hazard or interfere with views? Light or glare from the finished project is not expected to be a safety hazard, nor interfere with views. Light from the equipment storage building would be screened by the adjacent dental building and hedge. The proposed concrete storage bins are six feet tall, and would block headlights as the vehicles pick-up and deliver materials to the site or visit the Vactor dump. The multi-family development to the east is elevated, and set back, with a 6-foot high wooden fence on top of the intervening retaining wall, so the limited light produced by vehicles on the site would not impact their views. c. What existing off-site sources of light or glare may affect your proposal? No off-site sources of light would affect the proposal. d. Proposed measures to reduce or control light and glare impacts, if any: None are proposed. 12. RECREATION a. What designated and informal recreational opportunities are in the immediate vicinity? No recreational facilities are located in the immediate vicinity. b. Would the proposed project displace any existing recreational uses? If so, describe. The proposed project would not displace any existing recreational use. c. Proposed measures to reduce or control impacts on recreation, including opportunities to be provided by the project or applicant, if any: No measures are proposed to reduce or control impacts on recreation. 13. HISTORIC AND CULTURAL PRESERVATION a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe. A review of the records of the Washington State Department of Archaeology and Historic Preservation did not discover any known historic or cultural resources on or adjacent to the site. Page 23 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site? There are no landmarks or evidence of historic, archeological, scientific or cultural importance known to be on or next to the site. c. Proposed measures to reduce or control impacts, if any: If evidence or articles of historical, archaeological, scientific or cultural importance be encountered during construction of the project, construction would be halted and the State Department of Archeology and Historic Preservation would be notified. 14. TRANSPORTATION a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on-site plans, if any. Existing, and proposed access to the site is from Edmonds Way (SR-104), a Class 4, managed access facility, with a posted speed of 40 mph. Access to the site is currently from two points along the frontage. These two access points would be removed. Only one access is allowed and that access should meet the 250-foot access separation standard for a Class 4 facility. The proposed new access would be moved from milepost 27.48 to milepost 27.47 along Edmonds Way (SR-104). The access would be located approximately 245 feet thth north of 238 Street SW. The access would be located as far away from 238 Street SW as is feasible. There is an adjacent commercial development that has an access located 27 feet north of the site access. The proposed access would significantly Figure improve access separation and corner clearance over existing conditions (see 1 - Site Development Plan ). The proposed access point was checked to see if it met the road approach sight distance requirements set forth in Figure 920-6 of the WSDOT Design Manual. Based on the 40 mph posted speed and AWDVTE of 100 to 1500 for the access the required site distance is 295 feet. The site access to Edmonds Way is a full access; therefore, the sight triangle was checked to the left and right. To both the left and right of the proposed access there is over 300 feet of site distance. Vegetation is starting to get close to obscuring the sight distance and should be cleared from the Appendix B—Traffic Impact sight distance triangles within the right-of-way. (See Analysis for further details. b. Is the site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? The site is served by Community Transit. The nearest stop is with a half block of the th subject property located at 238 Street SW and SR-104. Page 24 Environmental Checklist – Olympic View Water and Sewer District Equipment and Materials Center Prepared by SHOCKEY/BRENT, Inc. EVALUATION FOR AGENCY USE ONLY c. How many parking spaces would the completed project have? How many would the project eliminate? The completed project would have four parking spaces. The completed project would eliminate approximately ten parking spaces, which are no longer needed, with the relocation of 12 employees to the new Administration and Operations site. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). The proposed site design would remove the two existing Edmonds Way access th points. The new access would be located approximately 245 feet north of 238 St SW. This would provide additional access spacing along Edmonds Way and reduce potential conflict points. The frontage would be constructed with new concrete gutter, curb and sidewalk, to connect to the existing sidewalks and street improvements. e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. No; the proposed project would not use water, rail or air transportation. f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur. With the removal of the administrative and operations functions of the District to the proposed Snohomish County site, 12 staff would be removed with the result of a significant reduction in vehicular trips (a net reduction of -15.7 average daily drips, and -2 AM and -2 PM peak hour trips). The site would be used intermittently, throughout the workday, and vary with seasonal/weekly project demands. g. Proposed measures to reduce or control transportation impacts, if any: The removal of the Administration and Operation Office portion of the existing site development would generate fewer trips than the existing condition; therefore, no traffic mitigation is proposed. 15. PUBLIC SERVICES a. Would the project result in an increased need for public services (for example: fire protection, police protection, health care, schools, other)? If so, generally describe: There would not be an increased need for public services. b. Proposed measures to reduce or control direct impacts on public services, if any.
