Posts may be pin-pin -okay. Most shear walls with <150 plf applied lateral loads have low unit shear force thus no holdowns are required by inspection(uplift is easily handled by anchor bolts and/or bottom plate attachment to framing below.) • Where plate to plate height of shear panel>3.5:1, use shear transfer around opening(STAO)and height of opening for aspect ratio calc. Use continuous king studs at sides of opening and no joints in sheathing within 2'of opening corners to achieve STAO. • I 2 3 J-1 1 1 4 lI ' V --- — - - - - - I - . -- 11' : ` 1 - --- Iw I I I i ` [/\' - . - -- _'- _-4 - - - - !11 . - II --_IN,: r 11 H Ij i III Th , .

Brief Description of the Project: To construct one Single-Family Residence (SFR) on a single legal lot within the City of Anacortes. The existing property is P , see Legal Description below. This SFR is being place on Lot 6 of the Cherry Court Short Plat, also known as City of Anacortes Short Plat No. SPL-2020-0003, A.F. NO. . The area of the future Lot 6 is 15,277 square feet (0.3507 acres), and is Zoned R1. LEGAL DESCRIPTON (of Pending Short Plat): Lot 6 of the Cherry Court Short Plat, also known as City of Anacortes Short Plat No. SPL-2020- 0003, A.F. NO. Pre Developed Conditions & Runoff on the future Lot 5: The property is vacant. The site slopes from the southeast to the northwest at a grade of approximately 4.0%. The property is bounded as follows: NORTH: Cherry Lane, a public street. EAST: Tract Y, SPL-2020-0003. South: Future Lot 5, SPL-2020-0003. West: Cherry Court, a public street. Developed Conditions & Runoff of The Site: The proposed improvements are as follows: Construct a SFR with an approximate lot coverage of 26.4%, and an impervious lot coverage of 31.7%. Detention is required for the Short Plat. Roof drains and footing drains will be hard lined to an infiltration bed located in the northerly portion of Lot 6, with an overflow to the existing stormwater collection system and the detention pond. The point of connection for Lot 6 is located in the northwest corner of the lot. After construction, landscaping will be provided to permanently stabilize the site from erosion. Summarize difficult site parameters, the natural drainage system, and drainage to and from adjacent properties, including bypass flows: The site slopes from the southwest to the northeast at a grade of approximately 4.0% and the disturbed soil seeded and/or mulched to reduce erosion. The only significant tributary drainage the lot may receive is from Lot 3. Lots 5 has it's own drainage self-contained prior to construction on Lot 6, so as not to impact Lot 6. Intercept drains may be installed to adequately eliminate impacts as needed. Hydrological Site Plan: Survey: A topographic survey has been performed by Lisser and Associates, showing the pre- developed condition, along with the existing contours at 2-foot intervals. The property is vacant. Soils Report: A Geotechnical Engineering Evaluation report was prepared by Geotest, Inc., dated February 26, and is already part of the record documents provided to the City of Anacortes. Recently we have had Linda Spicher, a septic designer do more detailed test pits to check the availability of infiltration for roof drains on Lots 1 and 6. Preliminary Development Site Plan Layout: An "Erosion Control & Site Plan" has been prepared by Landed Gentry Development, Inc., showing both the existing and proposed improvements as requested. See attached. A "Vicinity Map" has been provided on Sheet 1 of 1 of the "Erosion Control & Site Plan", attached. Construction Stormwater Pollution Prevention Plan (SWPPP): See attached. Other Permits: Building Permit for SFR. SWPPP - EXHIBIT "B" 4305 CHERRY COURT LOT 6, CHERRY COURT SHORT PLAT P Responses to the "13 Elements of SWPPP" (Construction Stormwater Pollution Prevention Plan) ELEMENT 1: Preserve Vegetation/Mark Clearing Limits The clearing limits will be marked by using either BMP C233: Silt Fence, or BMP C103: High Visibility Plastic or Metal Fence, as shown on the Erosion Control Plan. C233 is to be used along the east, west and north property lines and the C103 along the south property line. Preservation of the native top soil will be preserved as much as is practical by use of a stock pile as shown on the Erosion Control Plan. Stock pile location may vary. Stock pile shall be protected as indicated on the Erosion Control Plan. ELEMENT 2: Establish Construction Access BMP C105 shall be used as the construction access. Only one access point is proposed. No wheel wash is proposed. Any track out shall be cleaned daily by shoveling and/or sweeping. More frequent cleaning as necessary. ELEMENT 3: Control Flow Rates No flow rate controls are designed for the individual lot. However, a detention pond and wet pond were constructed with a flow control structure outlet. Erosion control BMPs described in ELEMENT 4, below will reduce velocity of flows. ELEMENT 4: Install Sediment Controls The following BMPs are proposed as temporary sediment controls: C233: Silt Fence To be place along the perimeter of the site to protect downstream properties from the transport of coarse sediment, as well as to mark the clearing limits for the construction crew and to alert the public as to the potential dangers of the ongoing onsite construction activity. C105: Stabilized Construction Entrance To be place in the location of the future driveway to provide a stable and clean point of access for construction vehicles. C121: Mulching To provide immediate temporary protection of exposed soil from erosion, as well as conserving moisture. C123: Plastic Covering Primarily used to protect the stock pile from erosion. May be used as a short term cover of small areas of exposed soil. Not intended for large areas. C140: Dust Control The primary source of dust control will be by spraying of the disturbed area with water. C220: Storm Drain Inlet Protection Onsite inlet protection will use Block & Gravel Curb Inlet Protection. Offsite inlet protection will use Catch Basin Filters manufactured for use at construction sites. C207: Check Dams Where drainage swale are created to convey stormwater, temporary gravel check dams may be used to reduce velocity and to dissipate flow energy. The following BMP improvement(s) are proposed for permanent sediment controls: C124: Sodding Sodding is to establish permanent turf for immediate erosion protection. C125: Top Soiling Provides a suitable growth medium for final site stabilization with vegetation. T5.13: Post-Construction Soil Quality and Depth Establishes soil quality and depth regains greater stormwater functions in the post development landscape, provides increased treatment of pollutants and sediments that result from development and habitation. ELEMENT 5: Soil Stabilization The following are temporary soil stabilization BMPs: C233: Silt Fence To be place along the perimeter of the site to protect downstream properties from the transport of coarse sediment, as well as to mark the clearing limits for the construction crew and to alert the public as to the potential dangers of the ongoing onsite construction activity. C105: Stabilized Construction Entrance To be place in the location of the future driveway on Latitude Circle, to provide a stable and clean point of access for construction vehicles. C121: Mulching To provide immediate temporary protection of exposed soil from erosion, as well as conserving moisture. C123: Plastic Covering Primarily used to protect the stock pile from erosion. May be used as a short term cover of small areas of exposed soil. Not intended for large areas. C140: Dust Control The primary source of dust control will be controlled spraying of the disturbed area with water. C220: Storm Drain Inlet Protection Onsite inlet protection will use Block & Gravel Curb Inlet Protection. Offsite inlet protection will use Catch Basin Filters manufactured for use at construction sites. C207: Check Dams Where drainage swale are created to convey stormwater, temporary gravel check dams may be used to reduce velocity and to dissipate flow energy. The following are permanent soil stabilization BMPs: C124: Sodding Establishes permanent turf for immediate erosion protection. C125: Top Soiling Provides a suitable growth medium for final site stabilization with vegetation. T5.13: Post-Construction Soil Quality and Depth Establishes soil quality and depth regains greater stormwater functions in the post development landscape, provides increased treatment of pollutants and sediments that result from development and habitation. ELEMENT 6: Protect Slopes C235: Straw Wattles Straw Wattles reduce the velocity and can spread the flow of rill and sheet runoff, and can capture and retain sediment. ELEMENT 7: Protect Drain Inlets C220: Storm Drain Inlet Protection Onsite inlet protection will use Block & Gravel Curb Inlet Protection. Offsite inlet protection will use Catch Basin Filters manufactured for use at construction sites. ELEMENT 8: Stabilize Channels and Outlets C207: Check Dams Where drainage swale are created to convey stormwater, temporary gravel check dams may be used to reduce velocity and to dissipate flow energy. ELEMENT 9: Control Pollutants All fuel, lubricants, paint, and/or other hazardous material shall be stored in a lockable, covered storage container if kept on site. ELEMENT 10: Control De-Watering Should dewatering become necessary, it should be pumped and dispersed to a well vegetated area within the project site. ELEMENT 11: Maintain BMPs A trained Certified Erosion and Sedimentation Control Lead (CESCL) will be on the job site. CESCL personnel are trained in and responsible for the proper maintenance of the erosion control BMPs. The CESCL will work with the City of Anacortes Inspector to maintain all BMPs. ELEMENT 12: Manage the Project A trained Certified Erosion and Sedimentation Control Lead (CESCL) will be on the job site. CESCL personnel are trained in and responsible for the proper maintenance of the erosion control BMPs. The CESCL will work with the City of Anacortes Inspector to maintain all BMPs.

TAB 1 (MINIMUM REQUIREMENT#1) • 1-2.5.1 Minimum Requirement#1 — Prepare a Stormwater Site Plan - 1.3— Preparation of a Stormwater Site Plan - 1.3.1 — Stormwater Site Plans: Step-by-Step Note: The level of detail needed for each step depends upon the project size. Provide a narrative description of each step. 1-3.1.1 Step 1 - Site Analysis: Collect and Analyze Information on Existing Conditions Site analysis shall be submitted as part of the Existing Conditions Summary above. Part of the information in this step should be used to help prepare the Construction Stormwater Pollution Prevention Plan. Purpose of the Site Analysis is to provide for a Low Impact Development site design that is intended to compliment the predeveloped conditions of the site. Existinr Condition of the proposed Lot 6 is that the site is vacant, has been stabilized during the plat construction. The site slopes from southeast to northwest at approximately 4.0%. Lot 6 is bounded to the north by Cherry Lane, to the east by Tract Y, to the south by proposed Lot 5, and to the west by Cherry Court. A geotechnical investigation has been conducted onsite which identified an underlying very dense, brown, slightly gravelly silty sand(weathered glacial till) at 3-4 feet below ground surface which has very limited infiltration capacity at depth. Per the geotechnical report(page 16), "conventional infiltration of stormwater on this site is not feasible': Dispersion methods for runoff from roofs and driveways will be promoted as noted further on within this report. Recently we have had Linda Spicher, a septic designer do more detailed test pits to check the availability of infiltration for roof drains on Lots I and 6. With the installation of a perimeter interceptor trench drain this type of onsite stormwater control to mitigate larger house sizes is feasible when accounting for a very small amount of infiltration in these areas. A underlying infiltration rate of 0.0267 in/hr and 0.0401 in/hr (correlating to 4 gallons/sf/day to 6 gallons/sf/day noted on the information provided by Linda Spicher) has been used. The Geotechnical report for this project indicated a perched groundwater elevation, which will be somewhat alleviated due to the interceptor drainage system put in place along the south and west property lines of the project area. Refer to both the septic testing performed by Linda Spicher and the Geotechnical Report prepared by Geotest for this project located within Appendix 2 at the end of this report. 1-3.1.2 Step 2 - Prepare Preliminary Development Layout Based upon the analysis of existing site conditions, locate the buildings, roads, parking lots, landscaping features, on-site stormwater management BMP's, and preliminary location of stormwater treatment and retention/detention facilities for the proposed development. Refer to the attached Erosion Control Plan and Site Plan Exhibit showing the proposed location of new walkway, driveway, SFR, shop, stormwater piping, infiltration area, dispersion area, detention pond, control structure and outlet piping from the site. 1-3.1.3 Step 3 - Perform Off-site Analysis (at Local Agency's Option): Use additional Sheets, if necessary, Per the City of Anacortes Stormwater Comprehensive Plan runoff from this project is discharged to Ace of Hearts Creek, which conveys runoff northeasterly approximately 0.7- miles, towards 32nd and M Avenue, then easterly approximately 0.5-miles east to "T" Avenue. From 32nd and "T"runoff waters are conveyed north in "T"Avenue another 0.2- 7 miles, before being discharged to Fidallo Bay to the northeast. Refer to the Downstream Exhibit attached with this report. 1-3.1.4 - Determine Applicable Minimum Requirements Per the attached Minimum Requirements for new development Figure 2.4.1. Minimum Requirements #1 through #5 apply to new and converted surfaces proposed with this short plat. Refer to attached highlighted Figure 2.4.1. 1-3.1.5 Step 5 - Prepare a Permanent Stormwater Control Plan See Post Construction Drainage Report,prepared by Ravnik and Associates, dated 12/21/2020. 1-3.1.6 Step 6 - Prepare a Construction Stormwater Pollution Prevention Plan (MR#2 — 13 Elements) Refer to Chapter 11-3— Planning for a detailed description of each element.

Provide details where applicable and if certain aspects are unnecessary or exempt, clearly justify. Details of the 13 Elements and the correlating BMPs are listed Above from the 2014 Stormwater Management Manual for Western Washington (SWMMWW). A link is provided on the City of Anacortes website, under Planning, Community, & Economic Development Department, as well as under Stormwater on the Engineering Division of Public Work's page. Owner Name Property Owner:Ronald Bayek /Project Owner:LG Anacortes, LLC Contact:Anna Nelson Site Address: 4305 Cherry Court,Anacortes, WA (P32077) Prepared By: LG Anacortes, LLC The Stormwater checklist or building permit determined that: ❑ The 13 elements must be addressed These elements must be addressed for construction activity adding under for construction activity adding 2,000 2,000 sq. ft. of hard surface area. sq. ft. or more of hard surface area. This means that an attached narrative and site plan are required with this document. Under each element, provide the BMP's that will be applicable to your project. Use the attached Tables provided. ELEMENT 1: Preserve Vegetation/Mark Clearing Limits ,IS 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. $5 Retain the duff layer, native top soil, and natural vegetation in an undisturbed state to the maximum degree practical. The clearing limits will be marked by using either BMP C233:Silt Fence, or BMP C103:High Visibility Plastic or Metal Fence, as shown on the Erosion Control Plan. C233 is to be used along the north, west, and east property lines. BMP C103 to be installed along the south property line. Preservation of the native top soil will be preserved as much as is practical by use of a stock pile as shown on the Erosion Control Plan. Stock pile location may vary. Stock pile shall be protected as indicated on the Erosion Control Plan. ELEMENT 2: Establish Construction Access it Limit construction vehicle access and exit to one route, if possible. at Stabilize access points with a pad of quarry spalls, crushed rock, or other equivalent BMPs, to minimize tracking onto roads. ❑ Locate wheel wash or tire baths on site, if the stabilized construction entrance is not effective in preventing tracking sediment onto roads. IS If sediment is tracked off site, clean the affected roadway thoroughly at the end of each day, or more frequently as necessary (ex: wet weather). Remove sediment from roads by shoveling, sweeping, or 13 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. BMP C105 shall be used as the construction access. Only one access point is proposed. No wheel wash is proposed. Any track out shall be cleaned daily by shoveling and/or sweeping. More frequent cleaning as necessary. ELEMENT 3: Control Flow Rates alle 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. # 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 improvement (e.g. impervious surfaces). * If permanent infiltration ponds are used for flow control during construction, protect these facilities from siltation during the construction phase. No flow rate controls are designed for the individual lot. However, a detention pond and wet pond were constructed with a flow control structure outlet. Erosion control BMPs described in ELEMENT 4, below will reduce velocity of flows. Down stream, the existing detentionj2ond shall be used to detain developed runoff and provide time for sediment to be filtered out prior to being discharged from the site. ELEMENT 4: Install Sediment Controls 1* Design, install, and maintain effective erosion controls and sediment controls to minimize the discharge of pollutants. * 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. $ 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. $ 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. $ 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. 1* Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas to increase sediment removal, and maximize stormwater infiltration. * 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. C233:Silt Fence To be place along the perimeter of the site to protect downstream properties from the transport of coarse sediment, as well as to mark the clearing limits for the construction crew and to alert the public as to the potential dangers of the ongoing onsite construction activity. 14 C105:Stabilized Construction Entrance To be place in the location of the future driveway to provide a stable and clean point of access for construction vehicles. C121:Mulching To provide immediate temporary protection of exposed soil from erosion, as well as conserving moisture. C123:Plastic Covering Primarily used to protect the stock pile from erosion. May be used as a short term cover of small areas of exposed soil. Not intended for large areas. C140: Dust Control The primary source of dust control will be by spraying of the disturbed area with water. C220:Storm Drain Inlet Protection Onsite inlet protection will use Block& Gravel Curb Inlet Protection. Offsite inlet protection will use Catch Basin Filters manufactured for use at construction sites. C207: Check Dams Where drainage swale are created to convey stormwater, temporary gravel check dams may be used to reduce velocity and to dissipate flow energy. The following BMP improvement(s) are proposed for permanent sediment controls: C124: Sodding Sodding is to establish permanent turf for immediate erosion protection. C125: Top Soiling Provides a suitable growth medium for final site stabilization with vegetation. Down stream, the existing detention pond shall be used to detain developed runoff and provide time for sediment to be filtered out prior to being discharged from the site. 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. 14 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 (Oct 1 —Apr 30): 2 days * Stabilize soils at the end of the shift before a holiday or weekend if needed based on the weather forecast. St 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. (NA) N Minimize soil compaction and, unless infeasible, preserve topsoil. The following are temporary soil stabilization BMPs: C233:Silt Fence To be place along the perimeter of the site to protect downstream properties from the transport of coarse sediment, as well as to mark the clearing limits for the construction crew and to alert the public as to the potential dangers of the ongoing onsite construction activity. C105:Stabilized Construction Entrance To be place in the location of the future driveway on Latitude Circle, toprovide a stable and clean point of access for construction vehicles. 15 C121:Mulching To provide immediate temporary protection of exposed soil from erosion, as well as conserving moisture. C123:Plastic Covering Primarily used to protect the stock pile from erosion. May be used as a short term cover of small areas of exposed soil. Not intended for large areas. C140:Dust Control The primary source of dust control will be controlled spraying of the disturbed area with water. C220:Storm Drain Inlet Protection Onsite inlet protection will use Block& Gravel Curb Inlet Protection. Offsite inlet protection will use Catch Basin Filters manufactured for use at construction sites. C207: Check Dams Where drainage swale are created to convey stormwater, temporary gravel check dams may be used to reduce velocity and to dissipate flow energy. The following are permanent soil stabilization BMPs: C124:Sodding Establishes permanent turf for immediate erosion protection. C125: Top Soiling Provides a suitable growth medium for final site stabilization with vegetation. T5.13:Post-Construction Soil Quality and Depth Establishes soil quality and depth regains greater stormwater functions in the post development landscape, provides increased treatment of pollutants and sediments that resultfrom development and habitation. 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 (Ex: track walking). N 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. N At the top of slopes, collect drainage in pipe slop 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/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. o Where 15-minute time steps are available in an approved continuous runoff model, they may be used directly without a correction factor. $ Place excavated material on the uphill side of trenches, consistent with safety and space considerations. N Place check dams at regular intervals within constructed channels that are cut down a slope. N Consider soil types 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. Ex: Use both mulching and straw erosion control blankets. C235:Straw Wattles Straw Wattles reduce the velocity and can spread the flow of rill and sheet runoff, and can capture and retain sediment. 16 ELEMENT 7: Protect 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. C220:Storm Drain Inlet Protection Onsite inlet protection will use Block& Gravel Curb Inlet Protection. Offsite inletprotection will use Catch Basin Filters manufacturedfor use at construction sites. 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 same peak volumetric flow rate as temporary pipe slope drains listed in Element 6, above. * 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. C207: Check Dams Where drainage swale are created to convey stormwater, temporarj jravel check dams may be used to reduce velocity and to dissipate flow energy. ELEMENT 9: Control Pollutants $ Design, install, implement, and maintain effective pollution prevention measures to minimize the discharge of pollutants. Q Handle and dispose of all pollutants, including waste materials and demolition debris that occur on-site 7* in a manner that does not cause contamination of stormwater. 1* 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. Wheel wash or tire bath wastewater should not include wastewater from concrete washout areas. $ 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 17 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. Adjust the pH of stormwater if necessary to prevent violations of the water quality standards. N 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. Do not use upland land applications for discharging wastewater from concrete washout areas. N Obtain written approval from Ecology and provide to the City before using chemical treatment other than CO2 or dry ice to adjust pH. N Woody debris may be chopped and spread on site. N Conduct oil changes, hydraulic system drain down, solvent and de-greasing cleaning operations, fuel tank drain down and removal, and other activities which may result in discharge or spillage of pollutants to the ground or into stormwater runoff using spill prevention measures, such as drip pans. $ Clean contaminated surfaces immediately following any discharge or spill incident. Emergency repairs may be performed on-site using temporary plastic placed beneath and, if raining, over the vehicle. All fuel, lubricants,paint, and/or other hazardous material shall be stored in a lockable, covered storage container if kept on site. Note: The contractor is required to have a spill prevention kit on site at all times. ELEMENT 10: Control De-Watering Not Applicable, no dewaterinj'is anticipated ❑ 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: 1. Infiltration 2. Transport off-site in a vehicle, such as a vacuum flush truck, for legal disposal in a manner that does not pollute state waters. 3. Ecology-approved on-site chemical treatment or other suitable treatment technologies. 4. Sanitary or combined sewer discharge with local sewer district approval, if there is no other option. 5. Use of a sedimentation bag with outfall to a ditch or swale for small volumes of localized dewatering. ❑ 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 a 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 18 II 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. N 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. Some temporary erosion and sediment control BMPs are bio-degradable and designed to remain in place following construction such as compost socks. N 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. N Remove or stabilize trapped sediment on site. Permanently stabilize disturbed soil resulting from removal of BMPs or vegetation. A trained Certified Erosion and Sedimentation Control Lead(CESCL) will be on the job site. CESCL personnel are trained in and responsible for the proper maintenance of the erosion control BMPs. The CESCL will work with the City of Anacortes Inspector to maintain all BMPs. ELEMENT 12: Manage the Project— Projects subject to Minimum Requirements 1-9 must have a Certified Erosion and Sediment Control Lead (CESCL)for site inspections. Projects subject to Minimum Requirements 1-5 do not require the inspector to be certified. 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. NI Phase development projects to the maximum degree practicable and take into account seasonal work limits to prevent soil erosion and prevent transporting sediment from the site during construction. N Inspection and monitoring — Inspect, maintain, and repair all BMPs as needed to assure continued performance of their intended function. N Maintain, update, and implement the SWPPP. N Clearing and grading activities for developments shall be permitted only if conducted using an approved site development plan (e.g., subdivision approval). N From Oct 1 through Apr 30, clearing, grading, and other soil disturbing activities is permitted only if shown that the site operator will prevent silt-laden runoff from leaving the site through a combination of the following: 1. Site conditions including existing vegetative coverage, slope, soil type, and proximity to receiving waters. 2. Limit activities and the extent of disturbed areas. 3. Proposed erosion and sediment control measures. Weather conditions can influence the seasonal limitation on site disturbance. The City of Anacortes has the authority to take enforcement action per AMC 19.76 Stormwater. N The following activities are exempt from the seasonal clearing and grading limitations: 1. Routine maintenance and necessary repair of erosion and sediment control BMPs; 2. 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 3. Activities where there is 100% infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities. The project contractor will prepare a SWPPP that will expand on the site's erosion controls as required. The SWPPP and CESL will assure site is manaj'ed properly Note: The project is required to have a CESCL and will need to maintain a project SWPPP for the duration of construction 19 ELEMENT 13: Protect Low Impact Development BMPS If implementing any bioretention facilities or rain gardens, refer to the applicable BMP sections of the Manual for requirements. BMP T510B Downspout Dispersion and to be implemented on this site. Compaction of soil in dispersion areas to be avoided. Steven Baughn 01/20/2021 Applicant Signature Date TAB 3 (MINIMUM REQUIREMENT#3) • 1-2.5.3 Minimum Requirement#3 —Source Control of Pollution All known, available and reasonable source control BMP's must be applied to all projects. Source control BMP's must be selected, designed, maintained according to the reference Ecology Manual. The intent of source control BMP's is to prevent stormwater from coming in contact with pollutants. They are a cost-effective means of reducing pollutants in stormwater, and, therefore, should be considered in all projects. There is no source control pollution anticipated within this Residential Subdivision and thus this Minimum Requirement is not necessary 20 TAB 4 (MINIMUM REQUIREMENT#4) • Minimum Requirement#4— Preservation of Natural Drainage Systems and Outfalls Natural drainage patterns shall be maintained and discharges from the project shall occur at the natural location, to 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. All outfalls require energy dissipation. The objective is to preserve and utilize drainage systems to the fullest extent because of the multiple stormwater benefits these systems provide; and to prevent erosion at the downstream of the discharge location. Refer to the reference manual for supplemental guidelines and additional information under this section. Will this project disturb the Natural Drainage System or Outfall of the project Site? Yes\No. If yes, refer to section 1.2.5.4 for Supplemental Guidelines for additional information. No. This project will not disturb the natural drainage system or outfall from the project site. Runoff will be detained prior to being released via a control structure at the site's northeast corner, as occurs today. 21 TAB 5 (MINIMUM REQUIREMENT#5) • Minimum Requirement#5 — On-site Stormwater Management This project triggers Minimum Requirements #1 throuih #5, and is on a parcel located within the City limits, this project has the choice to either utilize the On-site Stormwater Management BMP's from List#2 for each type of surface noted on the list; or, can demonstrate compliance with the LID Performance Standard. This project will use List#2 to meet the requirements of On-site Stormwater Management as specified below. Is this project Flow Control Exempt? No (Yes\No) (See Appendix I-E: Flow Control-Exempt Surface Water). If yes, provide reasoning from the applicability section of 1-2.5.7 Minimum Requirement#7: Flow Control). If No, then the project triggers Minimum Requirement#7 (1-2.5.7) and possibly Minimum Requirement#8 (1-2.5.8). Projects triggering Minimum Requirements 1 through 9, must meet the requirements in 1-2.5.5 Minimum Requirement 5—On-site Stormwater Management. To meet the requirements of MR #5 for this project, each surface on List#2, as listed below, will be reviewed and BMP's will be considered in the order listed for that type of surface. The first BMP for the surface that is considered feasible shall be implemented. Lawn and Landscaped Area: • BMP T5.13: Post-Construction Soil Quality and Depth. (Refer to DOE Figure V-5.3.3) Refer to this site for requirements and specifications. All projects are required to utilize this BMP. http://www.soilsforsalmon.orq/pdf/Soil BMP Manual.pdf See Appendix 3 for the "Model Soil Management Plan for BMP T5.13" to be submitted with Drainage Report and Application Material. An alternate document acceptable to the City of Anacortes is a Test Report provided by the Soils Supplier that identifies the soils to be used meet the specifications outlined under Minimum Requirement 5. The specifications are in both WSDOT and CSI Formats. For specifications, refer to the above referenced PDF. This submittal can be a deferred submittal since most projects are not sure who the supplier will be at the time of building permit application. Since this project triggerings Minimum Requirements 1 through 9, the Test Report will be provided to the Engineering Department. This submittal will be deferred since this project is not sure who the supplier will be at this time. 22 List #2 — Project Triggering Minimum Requirement 1 through 9 For each surface, consider the BMPs in the order listed for that type of surface. Use the first BMP that is considered feasible. No other On-site Stormwater Management BMP is necessary for that surface. Provide feasible detail under each BMP with maintenance and operations specifications in Minimum Requirement 5. Roofs: 1. BMP T5.30: Full Dispersion Feasible\Infeasible If infeasible, explain the criteria: Full Dispersion, BMP T5.30, is not feasible as the site is not retaining at least 65% of its natural forested or native condition. Or, T5.10A: Downspout Full Infiltration Feasible\Infeasible If infeasible, explain the criteria: Full Infiltration, BMP T5.10A, due to the low infiltration rate in the underlying soils this BMP is not required, however will be incorporated into the design for the individual lot development to infiltrate roof water from new houses on Lots 1 and Lot 6 as noted further on in this report as noted. 2. BMP T7.30: Biorention Cells, Swales and Planter Boxes Feasible\Infeasible If infeasible, explain the criteria: Bioretention is not feasible as the site's underlying soils have an infiltration rate less than 0.3 inches per hour. 3. BMP T5.10B: Downspout Dispersion Systems Feasible\Infeasible If infeasible, explain the criteria: Dispersion is being proposed for roof runoff with the exception of Lot I and Lot 6. Lot 1 and 6 will utilize the partial infiltration as mentioned above. 4. BMP T5.10C: Perforated Stub-out Connections Feasible\Infeasible If infeasible, explain the criteria: Not applicable since Downspout Dispersion Systems are proposed Other Hard Surfaces: List#2 1. BMP T.5.30 Full Dispersion Feasible\Infeasible If infeasible, explain the criteria: Full Dispersion, BMP T5.30, is not feasible as the site is not retaining at least 65% of its natural forested or native condition. 2. BMP T5.15: Permeable Pavements Feasible\Infeasible If infeasible, explain the criteria: 23 Permeable Pavement is not feasible per the 2014 DOE Manual as the site's infiltration capacity is less than 0.30 inches per hour, however this BMP can be incorporated using the low infiltration rates available if upon site development it is deemed necessary. 3. BMP T7.30: Biorention Cells, Swales and Planter Boxes Feasible\Infeasible If infeasible, explain the criteria: Just as for Permeable Pavement, Bioretention is infeasible per the 2014 DOE Manual as the underlying soils within the site has a lack of infiltration capacity (less than 0.30 inches per hour). 4. BMP T5.12: Sheet Flow Dispersion Feasible\Infeasible If infeasible, explain the criteria: Sheet Flow Dispersion BMP T5.12 will be used to disperse driveway runoff for Lot 6 along with the disperse sidewalk areas. Lots 1 and 6 will have a sufficient room to provide a 50-foot dispersion area for driveways. Or, BMP T5.11: Concentrated Flow Dispersion Feasible\Infeasible If infeasible, explain the criteria: Lot 6 will not implement Concentrated Flow Dispersion per BMP T5.11.

APPENDIX 7 — Determining Construction Site Sediment Damage Potential The following rating system allows objective evaluation of a particular development site's potential to discharge sediment. Permittees may use the rating system below or develop alternative process designed to identify site-specific features which indicate that the site must be inspected prior to clearing and construction. Any alternative evaluation process must be documented and provide for equivalent environmental review. Step one is to determine if there is a sediment/erosion sensitive feature downstream of the development site. If there is such a site downstream complete step two, assessment of hydraulic nearness. If there is a sediment/erosion sensitive feature and it is hydraulically near the site then go to step three to determine the construction site sediment transport potential. v. STEP 1 —Sediment/Erosion Sensitive Feature Identification Sediment/erosion sensitive features are areas subject to significant degradation due to the effect of sediment deposition or erosion. Special protection must be provided to protect them. Sediment/erosion sensitive features include but are not limited to: i. Salmonid bearing fresh water streams and their tributaries or freshwater streams that would be Salmonid bearing if not for anthropogenic barriers; ii. Lakes; iii. Category I, II, and III wetlands; iv. Marine near-shore habitat; v. Sites containing contaminated soils where erosion could cause dispersal of contaminants; and vi. Steep slopes (25% or greater) associated with one of the above features. Identify any sediment/erosion sensitive features, and proceed to step two. If there are none the assessment is complete. Ace of Hearts Creek located approximately 125 feet easterly of the area of the site proposed for development and is noted as a "Fish Bearing"per the Department of Natural Resources FPARS Mapping. Furthermore, the slopes along the edge of Ace of Hearts Creek are slightly steeper than 25% in some locations. vi. STEP 2 — Hydraulic Nearness Assessment Sites are hydraulically near a feature if the pollutant load and peak quantity of runoff from the site will not be naturally attenuated before entering the feature. The conditions that render a site hydraulically near to a feature include, but are not limited to, the following: i. The feature or a buffer to protect the feature is within 200 feet downstream of the site. ii. Runoff from the site is tight-lined to the feature or flows to the feature through a channel or ditch. August 1, 2013, Modified January 16, 2015 Appendix 7- Determining Sediment Damage Potential Page 1 of 3 27 A site is not hydraulically near a feature if one of the following takes place to provide attenuation before runoff from the site enters the feature: vii. Sheet flow through a vegetated area with dense ground cover viii. Flow through a wetland not included as a sensitive feature ix. Flow through a significant shallow or adverse slope, not in a conveyance channel, between the site and the sensitive feature. Identify any of the sediment/erosion sensitive features from step one that are hydraulically near the site, and proceed to step three. If none of the sediment/erosion sensitive features are hydraulically near the site, the assessment is complete. Discharj'e from the sites proposed detention pond will be be released to an existinj'shallow ditch located along the south side of Orchard Avenue, which conveys runoff easterly to Ace of Hearts Creek as occurs today. x. STEP 3 — Construction Site Sediment Transport Potential Using the worksheet below, determine the total points for each development site. Assign points based on the most critical condition that affects 10% or more of the site. If soil testing has been performed on site, the results should be used to determine the predominant soil type on the site. Otherwise, soil information should be obtained from the county soil survey to determine Hydrologic Soil Group (Table of Engineering Index Properties for step 1.D) and Erosion Potential (Table of Water Features for step 1.E) When using the county soil survey, the dominant soil type may be in question, particularly when the site falls on a boundary between two soil types or when one of two soil types may be present on a site. In this case, the soil type resulting in the most points on the rating system will be assumed unless site soil tests indicate that another soil type dominates the site. Use the point score from Step 3 to determine whether the development site has a high potential for sediment transport off of the site. Total Score Transport Rating <100 Low ❑100 High A high transport rating indicates a higher risk that the site will generate sediment contaminated runoff. Refer to the attached worksheet prepared for this project notinj a score of 100 for this site, however this includes the development of all 6-future home sites, which will all not occur concurrently with plat infrastructure construction. Not accounting for home development reduces the total score below the threshold transport rating to "Low". Construction Site Sediment Transport Potential Worksheet A.

Most development within the City of Anacortes that involves disruption of soils, or construction of buildings, streets, parking lots, etc. requires a Stormwater review. Stormwater review requirements are based on either the amount of soil to be disturbed (grading,vegetation removal), or the amount of hard surface that is created or replaced on a site (building footprint, concrete, asphalt or gravel parking, sidewalk, etc.). Form BP-5 assists you in determining the level of stormwater review (applicable Minimum Requirements) required for your project. • STORMWATER SITE PLAN. The Stormwater Site Plan is the comprehensive report containing all of the technical information and analysis necessary for regulatory agencies to evaluate your project for compliance with stormwater requirements. The level of stormwater review and contents of the Stormwater Site Plan will vary with the type and size of the project, and individual site characteristics. Use Form BP-5 to determine the level of stormwater review and then complete the applicable Stormwater Minimum Requirements Form on the Public Works- Engineering Department Forms website and provide required submittal items/plans. • FORM BP-6: SITE PLANS& LANDSCAPE PLANS. Form BP-6 contains a list of all the items required to be shown on Site and Landscape Plans. • STRUCTURAL PLANS: Plans prepared and stamped by a State of Washington licensed professional structural engineer drawn at a scale approved by the Building Official clearly indicating the information required by the "Permits" section of the currently adopted International Building Code and Chapter 19.27 RCW (State Building Code Act, Statewide amendments), and City submittal forms including: structural members labeled as to size and spacing as well as bracing, blocking, bridging, special connectors, and anchor bolts; cross-section details, as needed,to show typical foundation,floor,wall, ceiling and roof construction; insulation of walls,floors and roof/ceiling; and details of stairs,fireplaces and special construction, if any.

PROPERTY WHERE WORK IS OCCURRING ADDRESS: 4305 Cherry Court PARCEL NUMBER(S) 2. GENERAL INFORMATION Most development within the City of Anacortes that involves disruption of soils, or construction of buildings, streets, parking lots,etc. requires a Stormwater review. Stormwater review requirements are based on either the amount of soil to be disturbed (grading,vegetation removal),or the amount of hard surface that is created or replaced on a site(building footprint,concrete,asphalt or gravel parking,sidewalk,etc.) This form is largely targeted for small projects and single family residences. For larger projects and more information please refer to the Anacortes Municipal Code(Chapter 19.76 Stormwater Management)and the latest Washington State Department of Ecology Stormwater Management Manual for Western Washington (Ecology Manual). 3. HARD SURFACE AREA CALCULATION Please calculate your project's hard surface amount;guidance is provided on the next page of this document. Use your project's total hard surface calculation to follow the flow chart(s) in this packet and determine the level of stormwater management required for you project. When determining your permit level or if stormwater thresholds are met or exceeded the entire project must be considered. A project is that portion of a property, properties,or right of way subject to land disturbing activities, new hard surfaces and replaced hard surfaces. The hard surface on your property will determine the storm water utility fees and the stormwater general facility charge. All new or replaced hard surfaces should be accounted for. Below are excerpts from the Anacortes Municipal Code and Ecology Manual that may assist you in preparing this information. "Hard surface area"means an impervious surface, a permeable pavement, or a vegetated roof. "Impervious surface"means a non-vegetated surface area which either prevents or retards the entry of water into the soil mantle as under natural conditions prior to development. A non-vegetated surface area which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. "Replaced impervious surface"means,for structures, the removal and replacement of impervious surfaces down to the foundation. For other impervious surfaces, the removal down to bare soil or base course and replacement.
