Encourage economic vitality through businesses, investment, redevelopment, and efficient use of land B. Encourage safe and comfortable access for pedestrians, transit, and motorists; C. Encourage attractive mixed-use development, affordable housing, and a variety of commercial uses D. Recognize the district’s evolving identity and sense of place, including distinctions between different parts of the district, and be sensitive to adjacent residential zones. 16.30.010 USES A. Permitted Primary Uses. 1. All permitted or conditional uses in any other zone in this title, except as specifically prohibited by subsection (C) of this section or limited by subsections (B) and (D) of this section Response: Senior living facilities are allowed in this zone and are not prohibited by subsection “C” or limited by subsections “B” and “D”. 16.60.020 SITE DEVELOPMENT STANDARDS - GENERAL Minimum Lot Area = None Response: Edmonds Senior Living Community has a lot area of 35,284 which meets the minimum lot area for a CG zone. Minimum Lot Width = None Response: Edmonds Senior Living Community street frontage along 212th St SW is approximately 213’; street frontage along 72nd Ave is approximately 159’ which meets the minimum lot width for a CG zone. Minimum Street Setback = 10’ Response: Edmonds Senior Living Community street frontage along 212th St SW and 72nd Ave will have at minimum a 10’ setback from the property line, which meets the minimum street setback for a CG zone. Minimum Side/Rear Setback = 0’ Response: Edmonds Senior Living Community is completely surrounded by CG zoned properties and requires a 0’ setback from the side and rear property lines. Due to existing utility easements and existing retaining walls located on the west and Attachment 2 ARCHITECTURE INTERIORS URBAN DESIGN BRANDING Edmonds Senior Living Community // 03.25.2019 ANKROM MOISAN 3 part of the south property line, the building footprint has been pulled away from the side and rear property lines providing additional separation from neighboring properties. Maximum Height = 75’ Response: Edmonds Senior Living Community has a height of 75’ to top of roof parapet as calculated by City of Edmonds form B41. This form requires that elevation grades are established at the 4 corners of the property. These elevations are added together and then divided by 4 to determine the average grade of the building pad. 75’ was then added to this number to establish the maximum building height. B. Maximum height for purposes of this chapter need not include railings, chimneys, mechanical equipment or other exterior building appurtenances that do not provide interior livable space. In no case shall building appurtenances together comprise more than 20 percent of the building surface area above the maximum height. Response: The maximum height was established to the top of the parapet surrounding, items that do not provide interior livable space such as elevator overruns and mechanical equipment were not included in this calculation.

To provide variety and interest in appearance, the following design elements should be considered, and a project shall demonstrate how at least four of the elements will be used to vary the design of the site: a. Building massing and unit layout; b. Placement of structures and setbacks; c. Location of pedestrian and vehicular facilities; d. Composition and character of open space, plant materials and street trees; e. Variety in architectural elements, facade articulation, and/or building materials; f. Roof variation in slope, height and/or materials. Response: Edmonds Senior Living Community will house underground parking, parking and resident amenity space and service space on level 1, and memory care Attachment 2 ARCHITECTURE INTERIORS URBAN DESIGN BRANDING Edmonds Senior Living Community // 03.25.2019 ANKROM MOISAN 14 units and specific memory care amenities on level 2. These 3 levels are best served with a rectangular floor template. Floors 3 through 6 serve assisted living units, the form of the building changes from a rectangular form to a “C” shaped form, allowing for exterior glazing for each assisted living unit. This also allows the secured Memory Care courtyard to be more open to the south allowing it to receive more sunlight. The first floor and basement forms are derived from the front yard setbacks and the utility easements on site. The façade of the building will contain a variety of architectural elements including but not limited to, various building materials, façade articulation seen through both overall form change and the inclusion of intermittent resident unit decks, and variation in roof height. Complies with a minimum of four elements previously listed. 2. Building Design and Massing. a. Buildings shall convey a visually distinct “base” and “top,” which may be achieved through differences in massing elements and/or architectural details. b. The bulk and scale of buildings of over 3,000 square feet in footprint shall be mitigated through the use of massing and design elements such as facade articulation and modulation, setbacks, step-backs, distinctive roof lines or forms, and other design details. c. Primary Frontage. On the primary frontage, to provide visual connection between activities inside and outside the building, 50 percent of the building facade between two and 10 feet in height, as measured from the adjacent sidewalk, shall be comprised of windows or doors that are transparent, the bottom of which may not be more than four feet above the adjacent sidewalk. A departure from this standard may be approved when the facade will not be visible from the public street due to the placement of other buildings on the site; provided, that the requirements of subsection (D)(2)(e) of this section shall apply. i. On the primary frontage, no vehicle parking shall be located within the first 20 feet of the first level of a building facing the street except where such parking is underground. Response: (a) A concrete base with a mixture of storefront glazing will convey visual distinctions between the top and bottom floors, with fiber cement panel siding articulating the middle and top bands of the building. (b) A front yard setback will pull the building away from the primary streets 10’ off the property line, reducing the overall bulk/scale of the building. Additional articulation of inset resident unit decks on the North façade will aid in pulling the overall form back further. This building will step back on the south property line on levels 3 through 6, providing additional reduction of the overall bulk of the building. (c) The primary frontage along 212th St SW will consist of storefront glazing, allowing a direct visual connection between the interior amenity spaces and the exterior sidewalk. No parking is provided with the first 20 feet facing the primary street. Complies with standards. Attachment 2 ARCHITECTURE INTERIORS URBAN DESIGN BRANDING Edmonds Senior Living Community // 03.25.2019 ANKROM MOISAN 15 d. All Other Building Frontages. All street-facing facades within 30 feet of a public street, other than for the primary frontage or those facing an alley or the last block of a dead-end street, shall comply with the standard below. i. Thirty percent of the building facade between two and 10 feet in height shall be made of windows or doors that are transparent, the bottom of which may not be more than four feet above the adjacent sidewalk. Windows shall not be mirrored or have glass tinted darker than 40 percent in order to meet this requirement. Response: The façade along 72nd Ave will have 30% of building façade be constructed of transparent windows and doors. Complies with standard. e. Wall Treatment. Building facades not subject to all requirements of subsection (D)(2)(c) or (d) of this section are intended to not display blank, unattractive walls to the public or to other building tenants. To accomplish this, walls greater than 30 feet in length shall have architectural treatment that incorporates at least four of the following elements into the design of the facade: i. Masonry (except for flat concrete block). ii. Concrete or masonry plinth at the base of the wall. iii. Belt courses of a different texture and color. iv. Projecting cornice. v. Projecting metal or wood canopy. vi. Decorative tilework. vii. Trellis containing planting. viii. Medallions. ix. Artwork or wall graphics. x. Vertical differentiation. xi. Decorative lighting fixtures. xii. Glazing. Response: The south and west facades will have various architectural wall treatments to keep from reading as a blank wall. Complies with standard. 16.60.040 Operating Restrictions Attachment 2 ARCHITECTURE INTERIORS URBAN DESIGN BRANDING Edmonds Senior Living Community // 03.25.2019 ANKROM MOISAN 16 A. Enclosed Building.

This project will result in greater than 5,000 SF of new plus replaced hard surface, therefore the site is classified as a Category 2 project site and shall comply with Minimum Requirements 1-9 of the City of Edmonds Stormwater Management Code. Table 1 below summarizes the City of Edmonds stormwater requirements. JURISDICTIONAL REQUIREMENTS Duration Analysis 2-year: Reduce to ½ pre-developed duration 50-year: Match pre-developed Water Quality Volume: N/A Water Quality Flow Rate: Full 2-year release rate from the detention facility* Downstream Analysis: ¼ mile *All continuous modelling to be performed using the “Puget East 36” precipitation time series, available in WWHM2012 by using WS-DOT data TABLE 1: Jurisdictional Requirements Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 6 EXISTING CONDITIONS AND HYDROLOGY EXISTING CONDITIONS The site is currently comprised of an existing office building with an associated parking lot area and landscaping. It is bound to the north by 212th Street SW, to the east by 72nd Avenue W, to the south by an apartment complex, and to the west by a townhome development. There is existing storm drainage infrastructure on-site that runs west to east and conveys off-site stormwater from the Hyde Park Townhomes to the municipal conveyance system in 72nd Avenue West. See Figure 3 for the Existing Conditions Map. Figure 3: Existing Conditions Map The property slopes from an approximate elevation of 382 feet at the northern property line up to about 376 feet at the southern property line (Terracon). The NRCS soils map lists the site as having slopes in the range of approximately 8-15%. Per the City of Edmonds GIS critical areas map the site contains areas of landslide and erosion hazards (Figure 7). A Geotechnical Engineering Report was prepared for this project by Terracon Consultants, Inc on December 20, 2018 (Appendix C). Per the report on-site soils are comprised of asphalt and concrete pavement with a gravel base course at the surface; silty sand with variable gravel content with organics at 3.5’-7.5’ below grade; sand with silt content and trace gravel (recessional glacial outwash) Active storm pipe conveys runoff from Hyde Park Townhomes Off-site storm conveyance from Hyde Park Townhomes to west Existing pipe outfall connection to existing storm main Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 7 at 10’-13’ below grade; and, silty sand and sandy silt with variable gravel content (glacial till) up to 26’ below grade. Groundwater was encountered at 20.5 feet deep in one of four borings and was not encountered during or after drilling in the other three borings. There are no known surface water bodies in the immediate vicinity of the site including wetlands. A high-pressure gas line is located to the east of the project site within the 72nd Avenue West right-of- way, outside of the proposed development area. The site is zoned CG, General Commercial, and is within the Highway 99 Subarea Plan. EXISTING SITE HYDROLOGY Surface runoff from the existing site is collected in two catch basins located in the parking lot in the northern half of the site and is conveyed east to the existing municipal conveyance system in 72nd Avenue West. The site is in the Halls Creek Drainage Basin (Figure 4). The existing conditions survey prepared by Axis Survey and Mapping on January 19, 2018 indicates a stormwater drainage easement on the property that runs from the western edge of the site at its boundary with the Hyde Park Townhomes to the east. The easement encompasses a 12-inch storm conveyance pipes that originates from the Hyde Park Townhomes to the west and connects to the existing municipal conveyance system in 72nd Avenue West. This off-site storm conveyance system will be intercepted and rerouted around the proposed development. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 8 Figure 4: Watershed Map PROJECT SITE Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 9 DEVELOPED CONDITIONS AND HYDROLOGY DEVELOPED CONDITIONS The proposed project will consist of an approximately 163,100 GSF 6-story assisted living facility with approximately 92 assisted living units and 34 memory care units on a 0.78-acre parcel located at 21200 72nd Avenue W in Edmonds, Washington. All existing on-site structures will be demolished. DEVELOPED SITE HYDROLOGY Stormwater runoff from newly created pervious and impervious surfaces will be collected and routed to an on-site stormwater management system consisting of an approximately 21,000 CF underground detention vault for flow control. Flow from the vault will be restricted to pre-development forested conditions in accordance with City of Edmonds stormwater requirements. The controlled-released runoff will discharge to the municipal conveyance system in 72nd Avenue West by means of a stormwater pump system. All stormwater runoff from hard surfaces on-site will be managed and no existing, unmanaged hard surfaces will remain. As the project is not creating 5,000 SF or more of pollution-generating hard surface (PGHS) or 0.75 acres or more of pollution-generating pervious surface (PGPS), water quality treatment of not required. The total proposed non-pollution-generating impervious surface is approximately 0.629 acres, the proposed pervious areas is approximately 0.138 acres, and the proposed pollution-generating impervious area is 0.077 acres. Table 2, below, summarizes the threshold discharge areas, including off-site areas. Threshold Discharge Area Area (AC) Current Hard Surfaces 0.616 Proposed Hard Surfaces 0.706 New + Replaced PGPS 0.138 New + Replaced PGIS 0.077 New + Replaced PGHS 0.000 Effective Impervious Surface 0.706 Existing, Unmanaged Hard Surface to Remain 0.000 Disturbed Pervious Surface 0.228 Total Additional Hard Surfaces 0.090 Table 2: Threshold Discharge Areas Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 10 MINIMUM REQUIREMENTS Figure 5- Minimum Requirements Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 11 Minimum Requirement #1: Preparation of Stormwater Site Plans The City shall require a Stormwater Site Plan from all projects meeting the thresholds in ECDC 18.30.060.C. Stormwater Site Plans shall use site-appropriate development principles to retain native vegetation and minimize impervious surfaces to the extent feasible. Stormwater Site Plans shall be prepared in accordance with Chapter 3 of Volume 1 of the SWMMWW and the requirements in the Edmonds Stormwater Addendum. Response: A stormwater site plan that includes the design drawings and this report has been prepared for this development. The stormwater site plan has been designed using site-appropriate development principles to meet City of Edmonds guidelines to the maximum extent feasible. Minimum Requirement #2: Construction Stormwater Pollution Prevention Plan (SWPPP) All development projects are responsible for preventing erosion and discharge of sediment and other pollutants into receiving waters. Compliance with this minimum requirement can be achieved for an individual site if the site is covered under Ecology’s General NPDES Permit for Stormwater Discharges Associated with Construction Activities and fully implementing the requirements of that permit. A Construction SWPPP is required for all projects which a) result in 2,000 square feet or more of new plus replaced hard surface area, b) where a structure with an exterior hard surface area of at least 2,000 square feet is being demolished, c) which disturb 7,000 square feet or more of land, or d) when the site falls within the Earth Subsidence Landslide Hazard Area, Landslide Hazard Area or steep slope critical area. Response: A preliminary Construction SWPPP has been prepared and is included in the “CSWPP Analysis and Design” section of this report, below. A full Construction SWPPP report to be utilized by the contractor will be submitted with this permit submittal package as a separate document. Minimum Requirement #3: Source Control of Pollution All known, available and reasonable source control BMPs must be required for all projects approved by the City. Source control BMPs must be selected, designed, and maintained in accordance with Volume IV of the SWMMWW. Response: All known, available, and reasonable source control BMPs have been evaluated for applicability to this project. This includes, but is not limited to, Dust Control at Disturbed Land Areas, Landscaping and Lawn/Vegetation Management, and Maintenance of Stormwater Drainage and Treatment Systems. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 12 Minimum Requirement #4: Preservation of Natural Drainage Systems and Outfalls Natural drainage patterns shall be maintained, and discharges from the project site shall occur at the natural location, to the maximum extent practicable. The manner by which runoff is discharged from the project site must not cause a significant adverse impact to downstream receiving waters and down gradient properties. The discharge must have an identified overflow route that is safe and certain and leads to the ultimate outfall location (such as a receiving water or municipal drainage system). All outfalls require energy dissipation. To demonstrate compliance with this core requirement, all projects shall submit an off-site qualitative analysis. If an existing problem (or potential future problem after development) is identified, mitigation will be required to prevent worsening of that problem. A quantitative analysis may be required for any project deemed to need additional information or where the project proponent or the City determines that a quantitative analysis is necessary to evaluate the off-site impacts or the capacity of the conveyance system. Per the Edmond’s Stormwater Addendum, existing upstream flows must be accommodated without causing erosion or flooding impacts. Upstream flows shall not be routed through the project’s conveyance, treatment, or retention/detention systems, unless those systems are sized to control those flows. Upstream flows that are collected and routed through or around the site in a separate conveyance shall be dispersed at the downgradient property line, if feasible, or discharged at a project outfall (or outfalls) in a manner that does not violate the criteria below or cause the capacity of a conveyance system to be exceeded. Response: Natural drainage systems and outfalls will be maintained to the maximum extent feasible for the development of this site. Onsite stormwater will be collected in a new underground detention vault in the basement of the proposed building and routed to the existing municipal conveyance system in 72nd Ave W. In the proposed condition the existing drainage path and connection to the existing system in 72nd Ave W will be maintained. Minimum Requirement #5: On-Site Stormwater Management On-site Stormwater Management BMPs are required in accordance with the following project thresholds, standards, and lists to infiltrate, disperse, and retain stormwater runoff on-site to the extent feasible without causing flooding or erosion impacts. Category 2 project sites that discharge directly or indirectly to the City’s MS4 shall use On-Site Stormwater BMPs from List No.2 for all new plus replaced hard surfaces and land disturbed. Response: On-site stormwater management BMP’s have been evaluated in accordance with the City of Edmonds stormwater code requirements and the project is electing to use the List No. 2 option for on-site stormwater BMPs selection. Please see the Permanent Stormwater Control Plan – On-Site Stormwater Management BMP’s section of this report for more information. Minimum Requirement #6: Runoff Treatment The following require construction of stormwater treatment facilities: · Projects in which the total of pollution-generating hard surface (PGHS) is 5,000 square feet or more in a threshold discharge area of the project, or · Projects in which the total of pollution-generating pervious surfaces (PGPS) – not including permeable pavements – is 0.75 acres or more in a threshold discharge area, and from which there will be a surface discharge in a natural or man-made conveyance system from the site. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 13 Response: The total proposed pollution-generating hard surface (PGHS) is 2,580 SF and the pollution- generating pervious surface (PGPS) consisting of lawn and landscaping area is 5,811 SF. Therefore, water quality treatment facilities are not required.

Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 21 EXISTING IMPACTS AND CRITICAL AREAS Per the City’s website, there is an existing erosion hazard area along the northern and western perimeters of the site, most likely having to do with the existing sloped/retaining wall areas in those locations. The existing retaining wall along the western property boundary will be maintained in the developed condition. The shorter, existing retaining wall in the southwest corner of the site will be removed and replaced by retaining via the building. The downstream storm drainage system within 0.25 miles of the project is adjacent to existing erosion hazards, but there are no known impacts or problems associated with the drainage system. See Figure 7 below for the critical areas map. Figure 7- Critical Areas Map ¼ mile downstream location Project Site Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 22 POTENTIAL OFFSITE IMPACTS The proposed on-site stormwater management system will be designed according to the 2017 City of Edmonds Stormwater Management Code. No impacts to groundwater, surface waters, or drainage patterns are anticipated. 100-YEAR FLOOD/OVERFLOW CONDITION The stormwater conveyance system for this project has been designed to address all storm events, including the 100-year, 24-hour storm, in accordance with common industry practices. Please see FIRM map shown in Figure 8 below. The project site is in Zone X, which is outside the 500-year floodplain Figure 8: FIRM Map Project Site Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 23 PERMANENT STORMWATER CONTROL PLAN ON-SITE STORMWATER BMPs This project is electing to use the List No. 2 option for selection of on-site stormwater BMPs. After evaluating the stormwater BMPs provided in the City of Edmond’s Stormwater Addendum for applicability to this project site, it has been determined that a stormwater detention vault is required for on-site stormwater flow control. A vault has been sized using the Western Washington Hydrology Model (WWHM) per City of Edmonds requirements (using WSDOT data) and a report has been generated through the WWHM software (Appendix A). Based on the Geotechnical Engineering Report by Terracon Consultants (Appendix C), the on-site soils were evaluated for infiltration potential and sieve analyses were performed to estimate an infiltration rate. The glacial till soils observed exhibited an appreciable fines content and the soils were dense to very dense. The geotechnical engineer concluded that the site is not suitable for infiltration and, therefore, stormwater management via infiltration is not recommended. The following tables list the evaluated on-site BMPs and reasons for infeasibility based on the 2017 City of Edmonds Stormwater Management Code, Appendix A. Lawn and Landscape Areas BMP Feasible (Yes/No) Explanation Post-Construction Soil Quality and Depth Yes On-site disturbed areas that result in lawn or landscaping will be amended with compost or replaced with topsoil meeting Post-Construction Soil Quality and Depth requirements. Roofs BMP Feasible (Yes/No) Explanation Full Dispersion No A minimum forested or native vegetation flow path length of 100 feet (25 feet for sheet flow from a non-native pervious surface) cannot be achieved due to the nature of the zero-lot line development. Downspout Full Infiltration Systems No The site does not have outwash or loam soils. Geotechnical investigation does not recommend infiltration on this site. Bioretention or Rain Gardens No Geotechnical investigation does not recommend infiltration on this site. Downspout Dispersion Systems No For splash blocks, a vegetated flow path of at least 50 feet in length from the downspout to the downstream property line, structure, stream, wetland, slope over 15 percent, or other impervious surface is not feasible due to the nature of the zero-lot line development. For trenches, a vegetated flow path of at least 25 feet between the outlet of the trench and any property line, structure, stream, wetland, or impervious surface is not feasible due to the nature of the zero-lot line development. Perforated Stub- Out Connections No There is not at least 1 foot of permeable soil from the proposed bottom of the perforated stub-out connection trench to the highest estimated groundwater Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 24 table or other impermeable layer. Geotechnical investigation shows no permeable soils on site. Detention Vaults and Pipes Yes A detention vault has been sized using WWHM 2012 (Appendix A). Other Hard Surfaces BMP Feasible (Yes/No) Explanation Full Dispersion No A minimum forested or native vegetation flow path length of 100 feet (25 feet for sheet flow from a nonnative pervious surface) cannot be achieved due to the nature of the zero-lot line development. Permeable Pavement No Not feasible at multi-level parking garages such as this. Geotechnical investigation does not recommend infiltration on this site. Bioretention or Rain Gardens No Geotechnical investigation does not recommend infiltration on this site. Sheet Flow Dispersion No For flat to moderately sloped areas, at least a 10-foot-wide vegetation buffer for dispersion of the adjacent 20 feet of contributing surface cannot be achieved. Concentrated Flow Dispersion No A minimum 3-foot length of rock pad and 50-foot flow path OR a dispersion trench and 25-foot flow path for every 700 sq. ft. of drainage area (within applicable setbacks) cannot be achieved. Detention Vaults and Pipes Yes A detention vault has been sized using WWHM 2012 (Appendix A). Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 25 HYDROLOGIC MODELING The hydrologic analysis for this project was performed using Western Washington Hydrology Model (WWHM2012), based on matching flow durations.

Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 28 Figure 10: WWHM Tributary and Bypass Areas FLOW CONTROL SYSTEM The proposed flow control facility was designed in accordance with the 2014 Amendment to the 2012 Stormwater Manual for Western Washington and the 2017 City of Edmonds Stormwater Code. Pre- developed conditions are modeled as forested for all areas within the limits of disturbance. WWHM 2012 was used for flow control calculations. The proposed detention vault will have a live storage depth of 10 feet, a width of 30 feet, and a length of 70 feet. Basin data and results from the WWHM 2012 model are provided in Appendix A. CONVEYANCE SYSTEM ANALYSIS AND DESIGN The site conveys stormwater runoff through 6-inch, 8-inch, and 12-inch diameter conveyance pipes at a minimum slope of 1.0%. As shown in the Manning’s Calculations in Figure 11 below, the max. flow rate for a 6-inch storm drainage pipe at a min. slope of 1.0% is 0.5626 cfs. The max. flow rate for an 8-inch storm drainage pipe at a min. slope of 1.0% is 1.2117 cfs. The max. flow rate for a 12- inch storm drainage pipe at a min. slope of 1.0% is 3.5724 cfs. All of which are greater than the 100- year peak flow event (0.037 cfs). Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 29 Figure 11: Manning’s Calculations for 6-Inch, 8-Inch, and 12-Inch Pipes OPERATION AND MAINTAINANCE The proposed development will include an approximately 21,000 CF detention vault located at the basement level. The basement level will be accessible via a ramp leading down from the ground level. It is not anticipated that the detention vault will accumulate appreciable amounts of solids because the majority of collected runoff will be from clean roof surfaces. However, periodic maintenance is still required, including cleaning with a vactor truck. ProVac Clean Service has verbally confirmed that a typical vactor truck will need a height clearance of approximately 14 feet. Therefore, the truck will be able to access the vault through the vehicle and loading entry off 72nd Avenue W to park in the loading area and run the hose down the parking ramp to the detention vault at the basement level. See Figure 12 for the proposed vactor truck parking configuration. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 30 Figure 12: Proposed Vactor Truck Configuration A complete on-site BMP operation and maintenance manual is included in Appendix B. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 31 CSWPPP ANALYSIS AND DESIGN All erosion and sediment control measures shall be governed by the requirements of the City of Edmonds. A temporary erosion and sedimentation control plan will be prepared to assist the contractor in complying with these requirements. The Erosion and Sediment Control (ESC) plan will be included with the construction plans. Element 1: Preserve Vegetation/Mark Clearing Limits · Before beginning land disturbing activities, including clearing and grading, clearly mark all clearing limits, sensitive areas and their buffers, and trees that are to be preserved within the construction area. · Retain the duff layer, native top soil, and natural vegetation in an undisturbed state to the maximum degree practical. · Plastic, metal, or fabric fence may be used to mark the clearing limits. [Note: the difference between the practical use and proper installation of silt fencing and the proper use of clearing boundary fencing.] · If it is not practical to retain the duff layer in place, then stockpile it on-site, cover it to prevent erosion, and replace it immediately when you finish disturbing the site. Element 2: Establish Construction Access · Limit construction vehicle access and exit to one route, if possible. · Stabilize access points with a pad of quarry spalls, crushed rock, or other equivalent BMPs, to minimize tracking sediment onto roads. · Locate wheel wash or tire baths on site, if the stabilized construction entrance is not effective in preventing tracking sediment onto roads. · If sediment is tracked off site, clean the affected roadway thoroughly at the end of each day, or more frequently as necessary (for example, during wet weather). Remove sediment from roads by shoveling, sweeping, or pick up and transport the sediment to a controlled sediment disposal area. · Conduct street washing only after sediment is removed in accordance with the above bullet. · Control street wash wastewater by pumping back on site or otherwise preventing it from discharging into systems tributary to waters of the State. · Minimize construction site access points along linear projects, such as roadways. Street washing may require local jurisdiction approval. Element 3: Control Flow Rates · Protect properties and waterways downstream of development sites from erosion and the associated discharge of turbid waters due to increases in the velocity and peak volumetric flow rate of stormwater runoff from the project site, as required by local plan approval authority. · Where necessary to comply with the bullet above, construct stormwater retention or detention facilities as one of the first steps in grading. Assure that detention facilities function properly before constructing site improvements (e.g. impervious surfaces). · If permanent infiltration ponds are used for flow control during construction, protect these facilities from siltation during the construction phase. · Conduct downstream analysis if changes in off-site flows could impair or alter conveyance systems, streambanks, bed sediment, or aquatic habitat. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 32 · Even gently sloped areas need flow controls such as straw wattles or other energy dissipation / filtration structures. Place dissipation facilities closer together on steeper slopes. These methods prevent water from building higher velocities as it flows downstream within the construction site. · Outlet structures designed for permanent detention ponds are not appropriate for use during construction without modification. If used during construction, install an outlet structure that will allow for long-term storage of runoff and enable sediment to settle. Verify that the pond is sized appropriately for this purpose. Restore ponds to their original design dimensions, remove sediment, and install a final outlet structure at completion of the project. · Erosion has the potential to occur because of increases in the volume, velocity, and peak flow rate of stormwater runoff from the project site. The local permitting agency may require pond designs that provide additional or different stormwater flow control. These requirements may be necessary to address local conditions or to protect properties and waterways downstream. · Sites that must implement flow control for the developed site condition must also control stormwater release rates during construction. Construction site stormwater discharges shall not exceed the discharge durations of the pre-developed condition for the range of pre- developed discharge rates from ½ of the 2-year flow through the 10-year flow as predicted by an approved continuous runoff model. The pre-developed condition to be matched shall be the land cover condition immediately prior to the development project. This restriction on release rates can affect the size of the storage pond and treatment cells Element 4: Install Sediment Controls · The Permittee must design, install and maintain effective erosion controls and sediment controls to minimize the discharge of pollutants. At a minimum, the Permittee must design, install and maintain such controls to: o Construct sediment control BMPs (sediment ponds, traps, filters, etc.) as one of the first steps in grading. These BMPs shall be functional before other land disturbing activities take place. o Minimize sediment discharges from the site. The design, installation and maintenance of erosion and sediment controls must address factors such as the amount, frequency, intensity and duration of precipitation, the nature of resulting stormwater runoff, and soil characteristics, including the range of soil particle sizes expected to be present on the site. o Direct stormwater runoff from disturbed areas through a sediment pond or other appropriate sediment removal BMP before the runoff leaves a construction site or before discharge to an infiltration facility. Runoff from fully stabilized areas may be discharged without a sediment removal BMP but must meet the flow control performance standard in Element #3, bullet #1. o Locate BMPs intended to trap sediment on site in a manner to avoid interference with the movement of juvenile salmonids attempting to enter off-channel areas or drainages. o Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas to increase sediment removal, and maximize stormwater infiltration, unless infeasible. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 33 o Where feasible, design outlet structures that withdraw impounded stormwater from the surface to avoid discharging sediment that is still suspended lower in the water column. · Outlet structures that withdraw impounded stormwater from the surface to avoid discharging sediment that is still suspended lower in the water column are for the construction period only. If the pond using the construction outlet control is used for permanent stormwater controls, the appropriate outlet structure must be installed after the soil disturbance has ended. · Seed and mulch earthen structures such as dams, dikes, and diversions according to the timing indicated in Element #5. · Full stabilization includes concrete or asphalt paving; quarry spalls used as ditch lining; or the use of rolled erosion products, a bonded fiber matrix product, or vegetative cover in a manner that will fully prevent soil erosion. · The Local Permitting Authority may inspect and approve areas fully stabilized by means other than pavement or quarry spalls. · If installing a floating pump structure, include a stopper to prevent the pump basket from hitting the bottom of the pond. Element 5: Stabilize Soils · Stabilize exposed and unworked soils by application of effective BMPs that prevent erosion. Applicable BMPs include but are not limited to: temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics and matting, soil application of polyacrylamide (PAM), the early application of gravel base early on areas to be paved, and dust control. Control stormwater volume and velocity within the site to minimize soil erosion. · Control stormwater discharges, including both peak flow rates and total stormwater volume, to minimize erosion at outlets and to minimize downstream channel and stream bank erosion. · Soils must not remain exposed and unworked for more than the time periods set forth below to prevent erosion. o During the dry season (May 1 - Sept. 30): 7 days. o During the wet season (October 1 - April 30): 2 days. · Stabilize soils at the end of the shift before a holiday or weekend if needed based on the weather forecast. · Stabilize soil stockpiles from erosion, protect with sediment trapping measures, and where possible, be located away from storm drain inlets, waterways, and drainage channels. · Minimize the amount of soil exposed during construction activity. · Minimize the disturbance of steep slopes. · Minimize soil compaction and, unless infeasible, preserve topsoil. · Soils must not remain exposed and unworked for more than the time periods set forth above to prevent erosion for linear projects. · Soil stabilization measures should be appropriate for the time of year, site conditions, estimated duration of use, and potential water quality impacts that stabilization agents may have on downstream waters or ground water. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 34 · Ensure that gravel base used for stabilization is clean and does not contain fines or sediment. Element 6: Protect Slopes · Design and construct cut-and-fill slopes in a manner to minimize erosion. Applicable practices include, but are not limited to, reducing continuous length of slope with terracing and diversions, reducing slope steepness, and roughening slope surfaces (for example, track walking). · Divert off-site stormwater (run-on) or ground water away from slopes and disturbed areas with interceptor dikes, pipes, and/or swales. Off-site stormwater should be managed separately from stormwater generated on the site. · At the top of slopes, collect drainage in pipe slope drains or protected channels to prevent erosion. o Temporary pipe slope drains must handle the peak volumetric flow rate calculated using a 10-minute time step from a Type 1A, 10-year, 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate predicted by an approved continuous runoff model, increased by a factor of 1.6, may be used. The hydrologic analysis must use the existing land cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis must use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the Western Washington Hydrology Model (WWHM) to predict flows, bare soil areas should be modeled as "landscaped" area. · Place excavated material on the uphill side of trenches, consistent with safety and space considerations. · Place check dams at regular intervals within constructed channels that are cut down a slope. · Where 15-minute time steps are available in an approved continuous runoff model, they may be used directly without a correction factor. · Consider soil type and its potential for erosion. · Stabilize soils on slopes, as specified in Element #5. · BMP combinations are the most effective method of protecting slopes with disturbed soils. For example, use both mulching and straw erosion control blankets in combination. Element 7: Protect Permanent Drain Inlets · Protect all storm drain inlets made operable during construction so that stormwater runoff does not enter the conveyance system without first being filtered or treated to remove sediment. · Clean or remove and replace inlet protection devices when sediment has filled one-third of the available storage (unless a different standard is specified by the product manufacturer). · Where possible, protect all existing storm drain inlets so that stormwater runoff does not enter the conveyance system without first being filtered or treated to remove sediment. · Keep all approach roads clean. Do not allow sediment and street wash water to enter storm drains without prior and adequate treatment unless treatment is provided before the storm drain discharges to waters of the State. · Inlets should be inspected weekly at a minimum and daily during storm events. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 35 Element 8: Stabilize Channels and Outlets · Design, construct, and stabilize all on-site conveyance channels to prevent erosion from the following expected peak flows: o Channels must handle the peak volumetric flow rate calculated using a 10- minute time step from a Type 1A, 10-year, 24-hour frequency storm for the developed condition. Alternatively, the 10-year, 1-hour flow rate indicated by an approved continuous runoff model, increased by a factor of 1.6, may be used. The hydrologic analysis must use the existing land cover condition for predicting flow rates from tributary areas outside the project limits. For tributary areas on the project site, the analysis must use the temporary or permanent project land cover condition, whichever will produce the highest flow rates. If using the Western Washington Hydrology Model (WWHM) to predict flows, bare soil areas should be modeled as "landscaped area.” · Provide stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent streambanks, slopes, and downstream reaches at the outlets of all conveyance systems. · The best method for stabilizing channels is to completely line the channel with a blanket product first, then add check dams as necessary to function as an anchor and to slow the flow of water. Element 9: Control Pollutants · Design, install, implement and maintain effective pollution prevention measures to minimize the discharge of pollutants. · Handle and dispose of all pollutants, including waste materials and demolition debris that occur on-site in a manner that does not cause contamination of stormwater. · Provide cover, containment, and protection from vandalism for all chemicals, liquid products, petroleum products, and other materials that have the potential to pose a threat to human health or the environment. On-site fueling tanks must include secondary containment. Secondary containment means placing tanks or containers within an impervious structure capable of containing 110% of the volume contained in the largest tank within the containment structure. Double-walled tanks do not require additional secondary containment. · Conduct maintenance, fueling, and repair of heavy equipment and vehicles using spill prevention and control measures. Clean contaminated surfaces immediately following any spill incident. · Discharge wheel wash or tire bath wastewater to a separate on-site treatment system that prevents discharge to surface water, such as closed-loop recirculation or upland land application, or to the sanitary sewer, with local sewer district approval. · Apply fertilizers and pesticides in a manner and at application rates that will not result in loss of chemical to stormwater runoff. Follow manufacturers’ label requirements for application rates and procedures. · Use BMPs to prevent contamination of stormwater runoff by pH-modifying sources. The sources for this contamination include, but are not limited to: bulk cement, cement kiln dust, fly ash, new concrete washing and curing waters, waste streams generated from concrete grinding and sawing, exposed aggregate processes, dewatering concrete vaults, concrete pumping and mixer washout waters. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 36 · Adjust the pH of stormwater if necessary to prevent violations of the water quality standards. · Assure that washout of concrete trucks is performed off-site or in designated concrete washout areas only. Do not wash out concrete trucks onto the ground, or into storm drains, open ditches, streets, or streams. Do not dump excess concrete on site, except in designated concrete washout areas. Concrete spillage or concrete discharge to surface waters of the State is prohibited. · Obtain written approval from Ecology before using chemical treatment other than CO2 or dry ice to adjust pH. Element 10: Control De-Watering · Discharge foundation, vault, and trench dewatering water, which have characteristics similar to stormwater runoff at the site, into a controlled conveyance system before discharge to a sediment trap or sediment pond. · Discharge clean, non-turbid de-watering water, such as well-point ground water, to systems tributary to, or directly into surface waters of the State, as specified in Element #8, provided the de-watering flow does not cause erosion or flooding of receiving waters or interfere with the operation of the system. Do not route clean dewatering water through stormwater sediment ponds. Note that “surface waters of the State” may exist on a construction site as well as off site; for example, a creek running through a site. · Handle highly turbid or contaminated dewatering water separately from stormwater. · Other treatment or disposal options may include: o Infiltration. o Transport off-site in a vehicle, such as a vacuum flush truck, for legal disposal in a manner that does not pollute state waters. o Ecology-approved on-site chemical treatment or other suitable treatment technologies. o Sanitary or combined sewer discharge with local sewer district approval if there is no other option. o Use of a sedimentation bag with outfall to a ditch or swale for small volumes of localized dewatering. · Channels must be stabilized, as specified in Element #8. · Construction equipment operation, clamshell digging, concrete tremie pour, or work inside a cofferdam can create highly turbid or contaminated dewatering water. · Discharging sediment-laden (muddy) water into waters of the State likely constitutes violation of water quality standards for turbidity. The easiest way to avoid discharging muddy water is through infiltration and preserving vegetation. Element 11: Maintain BMPs · Maintain and repair all temporary and permanent erosion and sediment control BMPs as needed to assure continued performance of their intended function in accordance with BMP specifications. · Remove all temporary erosion and sediment control BMPs within 30 days after achieving final site stabilization or after the temporary BMPs are no longer needed. · Note: Some temporary erosion and sediment control BMPs are bio-degradable and designed to remain in place following construction such as compost socks. Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 37 · Provide protection to all BMPs installed for the permanent control of stormwater from sediment and compaction. All BMPs that are to remain in place following completion of construction shall be examined and placed in full operating conditions. If sediment enters the BMPs during construction, it shall be removed, and the facility shall be returned to the conditions specified in the construction documents. · Remove or stabilize trapped sediment on site. Permanently stabilize disturbed soil resulting from removal of BMPs or vegetation. Element 12: Manage the Project · Phase development projects to the maximum degree practicable and consider seasonal work limits. · Inspection and monitoring – Inspect, maintain, and repair all BMPs as needed to assure continued performance of their intended function. Conduct site inspections and monitoring in accordance with the Construction Stormwater General Permit or local plan approval authority. · Maintaining an updated construction SWPPP – Maintain, update, and implement the SWPPP in accordance with the Construction Stormwater General Permit. · Projects that disturb one or more acres must have, site inspections conducted by a Certified Erosion and Sediment Control Lead (CESCL). Project sites less than one acre (not part of a larger common plan of development or sale) may have a person without CESCL certification conduct inspections. By the initiation of construction, the SWPPP must identify the CESCL or inspector, who shall be present on-site or on-call at all times. · The CESCL or inspector (project sites less than one acre) must have the skills to assess the: o Site conditions and construction activities that could impact the quality of stormwater. o Effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. · The CESCL or inspector must examine stormwater visually for the presence of suspended sediment, turbidity, discoloration, and oil sheen. They must evaluate the effectiveness of BMPs and determine if it is necessary to install, maintain, or repair BMPs to improve the quality of stormwater discharges. Based on the results of the inspection, construction site operators must correct the problems identified by: · Reviewing the SWPPP for compliance with the 13 construction SWPPP elements and making appropriate revisions within 7 days of the inspection. · Immediately beginning the process of fully implementing and maintaining appropriate source control and/or treatment BMPs as soon as possible, addressing the problems no later than within 10 days of the inspection. If installation of necessary treatment BMPs is not feasible within 10 days, the construction site operator may request an extension within the initial 10-day response period. · Documenting BMP implementation and maintenance in the site log book (applies only to sites that have coverage under the Construction Stormwater General Permit). · The CESCL or inspector must inspect all areas disturbed by construction activities, all BMPs, and all stormwater discharge points at least once every calendar week and within 24 hours of any discharge from the site. (For purposes of this condition, individual discharge events that last more than one day do not require daily inspections. For example, if a stormwater pond discharges continuously over the course of a week, only one inspection is required Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 38 that week.) The CESCL or inspector may reduce the inspection frequency for temporary stabilized, inactive sites to once every calendar month · Phasing of Construction. o Phase development projects where feasible in order to prevent soil erosion and, to the maximum extent practical, and prevent transporting sediment from the site during construction. Revegetate exposed areas and maintain that vegetation as an integral part of the clearing activities for any phase. o Clearing and grading activities for developments shall be permitted only if conducted using an approved site development plan (e.g., subdivision approval) that establishes permitted areas of clearing, grading, cutting, and filling. Minimize removing trees and disturbing or compacting native soils when establishing permitted clearing and grading areas. Show on the site plans and the development site permitted clearing and grading areas and any other areas required to preserve critical or sensitive areas, buffers, native growth protection easements, or tree retention areas as may be required by local jurisdictions. · Seasonal Work Limitations o From October 1 through April 30, clearing, grading, and other soil disturbing activities is permitted only if shown to the satisfaction of the local permitting authority that the site operator will prevent silt-laden runoff from leaving the site through a combination of the following:  Site conditions including existing vegetative coverage, slope, soil type, and proximity to receiving waters.  Limit activities and the extent of disturbed areas.  Proposed erosion and sediment control measures. o Based on the information provided and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on site disturbance. The local permitting authority has the authority to take enforcement action –such as a notice of violation, administrative order, penalty, or stop-work order under the following circumstances: · If, during the course of any construction activity or soil disturbance during the seasonal limitation period, sediment leaves the construction site causing a violation of the surface water quality standard; or · If clearing and grading limits or erosion and sediment control measures shown in the approved plan are not maintained. · The following activities are exempt from the seasonal clearing and grading limitations: o Routine maintenance and necessary repair of erosion and sediment control BMPs; o Routine maintenance of public facilities or existing utility structures that do not expose the soil or result in the removal of the vegetative cover to soil. o Activities where there is one hundred percent infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities. · Coordination with Utilities and Other Contractors o The primary project proponent shall evaluate, with input from utilities and other contractors, the stormwater management requirements for the entire project, including the utilities, when preparing the Construction SWPPP. · Inspection and Monitoring Attachment 9 STORMWATER SITE PLAN NAVIX CA Senior Living – Edmonds, WA Page 39 o All BMPs must be inspected, maintained, and repaired as needed to assure continued performance of their intended function. Site inspections must be conducted by a person knowledgeable in the principles and practices of erosion and sediment control. The person must have the skills to 1) assess the site conditions and construction activities that could impact the quality of stormwater, and 2) assess the effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. o For construction sites one acre or larger that discharge stormwater to surface waters of the state, a CESCL must be identified in the construction SWPPP; this person must be on-site or on-call at all times. Certification must be obtained through an approved training program that meets the erosion and sediment control training standards established by Ecology. o Appropriate BMPs or design changes shall be implemented as soon as possible whenever inspection and/or monitoring reveals that the BMPs identified in the Construction SWPPP are inadequate, due to the actual discharge of /or potential to discharge a significant amount of any pollutant. · Maintaining an Updated Construction SWPPP o Retain the Construction SWPPP on-site or within reasonable access to the site. o Modify the SWPPP whenever there is a change in the design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state. · The SWPPP must be modified if, during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory authority, it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. Modify the SWPPP as necessary to include additional or modified BMPs designed to correct problems identified. Complete revisions to the SWPPP within seven (7) days following the inspection. Element 13: Protect Low Impact Development BMPs · Protect all Bioretention and Rain Garden BMPs from sedimentation through installation and maintenance of erosion and sediment control BMPs on portions of the site that drain into the Bioretention and/or Rain Garden BMPs. Restore the BMPs to their fully functioning condition if they accumulate sediment during construction. Restoring the BMP must include removal of sediment and any sediment-laden Bioretention/rain garden soils, and replacing the removed soils with soils meeting the design specification. · Prevent compacting Bioretention and rain garden BMPs by excluding construction equipment and foot traffic. Protect completed lawn and landscaped areas from compaction due to construction equipment. · Control erosion and avoid introducing sediment from surrounding land uses onto permeable pavements. Do not allow muddy construction equipment on the base material or pavement. Do not allow sediment-laden runoff onto permeable pavements. · Pavements fouled with sediments or no longer passing an initial infiltration test must be cleaned using procedures from the local stormwater manual or the manufacturer’s procedures. · Keep all heavy equipment off existing soils under LID facilities that have been excavated to final grade to retain the infiltration rate of the soils.

Attachment 10 Traffic Impact and Parking Demand Analysis Edmonds CA Senior Living - 21200 72nd Avenue W TENW May 16, 2019 Page 5 Traffic Impact Analysis The following section describes new trips generated by the proposed development, parking demand impacts, site access, safety and circulation issues, and identification of transportation mitigation to offset impacts. Project Trip Generation Published trip rate equations compiled by the Institute of Transportation Engineers (ITE) Trip Generation, 10th Edition, 2017, were used to estimate daily, a.m. and p.m. peak hour traffic that would be generated by the proposed development assuming the new Congregate Care Retirement Community (ITE Land Use Code 255), and removal of the existing Medical-Dental Office Building (ITE Land Use Code 720). As shown in Table 1, an estimated increase in daily net trip generation of approximately 70 daily trips and a decrease in peak trip generation would occur, with approximately 1 less a.m. peak hour vehicular trip and 3 less p.m. peak hour vehicular trips when applying standard average trip generation rates. A detailed summary of trip generation calculations is provided in Attachment A.

Parking Demand Analysis A parking impact analysis was conducted to evaluate the supply/demand generated by the proposed project. The parking impact analysis reviewed:  City of Edmonds parking requirements.  Parking demand of the proposed redevelopment using ITE rates. Please note that bicycle storage spaces are not required by the City of Edmonds for assisted living or other specialized facilities where the development services director finds that the targeted population is not likely to use bicycles. A parking supply of 97 parking stalls would be provided on-site by the proposed project. Attachment 10 Traffic Impact and Parking Demand Analysis Edmonds CA Senior Living - 21200 72nd Avenue W TENW May 16, 2019 Page 6 City of Edmonds Parking Requirements Based upon the City of Edmonds parking standards (Edmonds City Code and Community Development Code, Section 17.50.020 Parking Space Requirements), Table 2 summarizes minimum off-street parking stalls required for residential uses. As shown, the City of Edmonds would require 50 off-street parking stalls. As the project proposes 97 stalls, it would exceed the City minimum standards by 47 stalls. Table 2 Edmonds CA Senior Living - 21200 72nd Avenue W Parking Requirements Parking Component Minimum Off-Street Parking Requirements1 Size Total Rest Home, Nursing Home, Convalescent Home1 1 stall per 3 beds 149 beds in 126 Units 50 Total Minimum Off-Street Parking Supply Requirement 50 1 - Per Edmonds City Code and Community Development Code, Section 17.50.020.A.3 Parking Space Requirements. Project Parking Demand For the project, the Institute of Transportation Engineers Parking Generation, 5th Edition, 2019, and transit availability were all considered to determine parking demand for the proposed Edmonds CA Senior Living redevelopment. Based upon Land Use Code 254 for Assisted Living (39 sites surveyed), direct application of published rates in Parking Generation, 5th Edition, estimate the peak development parking demand at a total of 47 parking stalls (see Table 3). As noted in Parking Generation, 5th Edition, the peak period of parking demand for the proposed land use is between 11:00 a.m. and 3:00 p.m. when staff and other on-site activities that require outside support staff are at their peak levels. This is consistent with City code and therefore, adequate on-site supply would be provided. Parking generation rates for Congregate Care Facility (LU Code 253) were also reviewed, with a limited survey database of 7 sites and a lower parking generation rate than noted above. As such, the published rates for Assisted Living were applied as a conservative approach. Table 3 Edmonds CA Senior Living - 21200 72nd Avenue W Peak Parking Demand Demand Component Rate or Adjustment Peak Parking Demand Assisted Living (ITE LUC 254)1 Stalls = .95 X Ln(120)-0.69 47 Total Parking Demand With Adjustment 47 1 - Parking Generation, 5th Edition, ITE, 2019 and does not discount for vehicle availability factors. Attachment B contains the relevant pages of these published parking rates. Attachment 10 Traffic Impact and Parking Demand Analysis Edmonds CA Senior Living - 21200 72nd Avenue W TENW May 16, 2019 Page 7 Site Access and Safety Issues Two new site driveways for the project; one onto 72nd Avenue W near its southern property boundary (approximately 140 feet south of 212th Street SW), and one onto 212th Street SW (approximately 195 feet from 72nd Avenue W). Based upon the City of EdmondÊs driveway requirements (Edmonds City Code and Community Development Code, Section 18.80.060 Driveways and Curb Cut Requirements), the width of any commercial driveway and other nonresidential streets shall be 30 feet but no more than 40 feet. As proposed, the two 30-foot width driveways meet this design criterion. The proposed project would reconstruct frontage improvements along 72nd Avenue W and 212th Street SW that would fully integrate with the existing non-motorized facilities along these street systems, such as new curbs, gutters, 7- to 10-foot sidewalks, 5-foot wide streetscape zone between the travel lane and sidewalk, and sidewalk or driveway ramps to meet City standards and comply with ADA requirements. Field work was conducted by TENW at the site driveway onto 72nd Avenue W on March 20, 2019. The minimum stopping sight distance is 250 feet and the minimum entering sight distance is 390 feet on a 35 mph design speed (25 mph posted speed) based on guidelines set forth by the American Association of State and Highway Transportation Officials (AASHTOÊs) A Policy on Geometric Design of Highway and Streets (commonly referred to as the „Green Book‰). Based upon the City of Edmonds Standard Detail TR-590, Sight Distance ă Setback Lines, the minimum entering sight distance for a residential driveway is 250 feet and for a commercial driveway is 360 feet for a 35 mph design speed (25 mph posted speed). Driver entering sight distance is approximately 500 feet to the north and greater than 800 feet to the south of the project site driveway onto 72nd Avenue W. Entering sight distance on 212th Street W is estimated in excess of 700 feet in either direction. Therefore, adequate entering sight distance onto 72nd Avenue W and 212th Street W meet minimum sight distance requirements. Mitigation The proposed Edmonds CA Senior Living redevelopment would construct 126 senior housing units in a 6-story building and remove an existing 6,672 square foot medical office building at 21200 72nd Avenue W, located on the southwest quadrant of the 72nd Avenue W and 212th Street SW intersection in Edmonds, WA. The following mitigation measures may be required as part of the project redevelopment:  The proposed project would reconstruct frontage improvements along 72nd Avenue W and 212th Street SW that would fully integrate with the existing non-motorized facilities along these street systems, such as new curbs, gutters, 7- to 10-foot sidewalks, 5-foot wide streetscape zone between the travel lane and sidewalk, and sidewalk or driveway ramps to meet City standards and comply with ADA requirements. Attachment 10 Traffic Impact and Parking Demand Analysis Edmonds CA Senior Living - 21200 72nd Avenue W TENW May 16, 2019 Page 8 Traffic Impact Fees With the construction of 126 senior housing units and the removal of 6,672 square feet of an existing medical office building, the estimated traffic impact fee for the project development would be approximately $21,888.42 based on current traffic impact fee rates for 2019 and beyond (Edmonds City Code and Community Development Code, Section 3.36.125 Street Impact Fee Rates).

An environmenøl impact statãment (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help yo' arrd the- agency identiff impacts from your proposal (and to reduce or avoiã impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. f n sûu ctìo ns for Ap p lic ants : This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS' Answer the questions briefly, with the most precise information known, or give the best description you can. you must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposat, write 'to not know" or does not apply". Complete answers to the questions now may avoid unnecessary delaYs later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if yo,, cuo. If you have problems, the governmental agencies can assist you. The checklist questions appty to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additionâtlnrormátion that wiliheip describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain yo* *rï"., or próvideãdáitional information reasonably related to determining if there may be significant adverse impact.
