About this Pollution Prevention Plan This is Anacortes’s Small Site Construction Stormwater Pollution Prevention Plan (“Construction SWPPP”) intended to ensure your construction project minimizes erosion and does not contribute pollution, including sediment, to stormwater. This SWPPP is primarily intended for projects under 2,000 sq ft. This plan uses certain Best Management Practices (“BMPs”) from the Stormwater Management Manual. Some detailed descriptions are included; the remainder and additional information are available at https://fortress.wa.gov/ecy/publications/parts/1410055pa rt4.pdf#page=27 The listed BMPs are the minimum necessary; if erosion occurs, you must add additional BMPs as necessary to control it. You should include your Construction SWPPP in your contract with your builder. You must keep a copy of this SWPPP on the construction site or within reasonable access to the site for construction and inspection personnel at all times. Property owners and contractors are responsible for ensuring all aspects of BMPs are followed, including those not shown on the detail sheets. This Construction SWPPP should be considered a living document and must be updated as needed to reflect site conditions. Preserve Vegetation/Mark Clearing Limits Before any land disturbance, 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 natural vegetation in an undisturbed state to the maximum extent practical. Use these BMPs: • C101 to preserve natural vegetation • C102 to establish buffer zones around important vegetation you want to save • C103 High Visibility Fencing to mark the boundaries of your buffers • C233 Silt Fence to ensure sediment doesn’t leave the site Establish Construction Access Construction vehicles can damage or compact soils, create sediment pollution, or track sediment onto public roads. All equipment and vehicles that access the construction area must use an existing driveway or a stabilized construction entrance. • Use BMP C105 Stabilized Construction Entrance wherever traffic will be entering or leaving a construction site if paved roads are within 1,000 ft of the site. Construct a 12-inch thick pad of 4-inch to 8- inch quarry spalls, a 4-inch course of asphalt treated base, or use existing pavement. Place a separation geotextile under the spalls to prevent fine sediment from pumping up into the rock pad. Install the construction entrance prior to any vehicles entering the site, at the location shown on the site plan. Create only one construction entrance per site. 1 2 1b 1b 1b 2 1a 4 7 9a 9b 5 9b page 3 of 5 • Use BMP C103 High Visibility Fencing to restrict traffic to the construction entrance. • Remove any sediment that is tracked onto pavement by shoveling or street sweeping and remove the collected sediment or stabilize it on site. Control Flow Rates (not shown) Stormwater on a cleared site can create significant flows that can damage downstream properties. Protect properties and waterways downstream of the project site from erosion and the associated discharge of turbid waters. If your project is required to control flow rates, you must use the following BMPs as shown on the approved site plan: • C203 Water Bars • C209 Outlet Protection • C235 Straw Wattles Install Sediment Controls When land is cleared of vegetation, stormwater can pick up sediment, a pollutant. BMPs can prevent sediment from leaving the site. You must install sediment controls before land disturbance to effectively minimize and control the discharge of pollutants and sediments. Use and properly install BMP C233 Silt Fence. You must bury the filter fabric as shown in the diagram in order for the BMP to be effective. You must repair the silt fence if it is damaged. Consider the following additional BMPs: • C231 Brush Barrier • C232 Gravel Filter Berm • C234 Vegetated Strip • C235 Straw Wattles Note that C230 Straw Bale Barrier is no longer an approved BMP. Stabilize Soils Leaving soils devegetated or exposed needlessly creates erosion and sediment problems. • Stabilize all exposed soils whenever construction work will stop for more than two days at a time during the wet season (October 1 to April 30) or 7 days the rest of the year (the dry season). • Stabilize all exposed soils at the end of the shift before a holiday or weekend. • Stabilize all exposed soils with either vegetation, mat coverings, mulching, or in those areas to be paved, a compacted base material. • Use BMP C123 Plastic Covering over all stockpiles with plastic or burlap if left unworked. Place sand- filled burlap or geotextile bags every 3 to 6 ft along seams and tie them together with twine to hold them in place. • If you excavate soil for the foundation, backfill that soil against the foundation and grade it to drain away from the building. Once the disturbed landscape areas are graded, you must seed or sod the grass areas. Consider the following additional BMPs: • C120 Temporary and Permanent Seeding • C121 Mulching • C122 Nets and Blankets • C124 Sodding • C125 Topsoiling/Composting • C131 Gradient Terraces • C140 Dust Control Protect Slopes (not shown) Slopes can be especially vulnerable to erosion, but BMPs can mitigate sediment problems. Design and construct cut-and-fill slopes to minimize erosion. Use the following practices: • Reduce continuous length of slope with terracing and diversions • Reduce slope steepness • Roughen slope surfaces • Use BMP C123 Plastic Covering over all exposed slopes • Use BMP C120 Temporary and Permanent Seeding as soon as possible on exposed slopes Manage off-site stormwater (run-on) separately from stormwater generated onsite. Divert off-site stormwater or groundwater away from slopes and disturbed areas with interceptor dikes, pipes, or swales. You may not create cut slopes over 4 feet high or slopes steeper than 2 feet horizontal to 1 foot vertical. Fill slopes may not exceed 4 feet high or 3 feet horizontal to 1 foot vertical. Slopes that exceed these criteria require engineering. Consider the following additional BMPs: • C121 Mulching • C122 Nets and Blankets • C124 Sodding • C203 Water Bars • C208 Triangular Silt Dike (Geotextile-Encased Check Dam Protect Drain Inlets Storm drains are designed to collect and transport clean stormwater, not water contaminated with sediment or other pollutants. Storm drain inlets must be protected so that runoff does not enter the 3 4 5 6 7 page 4 of 5 stormwater system without first being filtered or treated or both. • Use BMP C220 Storm Drain Inlet Protection to protect all proposed and existing storm drain inlets during construction so that stormwater runoff does not enter the stormwater conveyance system without first being filtered or treated (or both) to remove sediment or other pollutants. • 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). • Keep all approach roads clean. • Do not allow sediment and street wash water to enter storm drains without treatment. Stabilize Channels and Outlets Stormwater channels and outlets can themselves erode unless stabilized with rock or other armoring. Design, construct, and stabilize all on-site conveyance channels to prevent erosion as needed. Use BMP C209 Outlet Protection to provide stabilization, including armoring material adequate to prevent erosion of outlets, adjacent streambanks, slopes, and downstream reaches at the outlets of all conveyance systems. Consider the following additional BMPs: • C122 Nets and Blankets • C202 Channel Lining Control Pollutants Waste materials, demolition debris, and other pollutants that occur onsite during construction can contaminate the stormwater system unless managed. Cement and related products can modify the pH 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. Anytime you pour concrete, perform washout of the concrete trucks following BMP C154 Concrete Washout Area at designated washout areas only. Locate washout areas at least 50 ft from sensitive areas such as storm drains, open ditches, or water bodies, including wetlands. Clean contaminated surfaces immediately following any spill incident. Apply fertilizers and pesticides in a manner and at rates that will not result in loss of chemical via stormwater runoff. Use the following additional BMPs: • C151 Concrete Handling • C152 Sawcutting and Surfacing Pollution Prevention • C153 Material Storage, Delivery, and Containment Control De-Watering (not shown) De-watering water extracted from foundations, vaults, or trenches, has similar characteristics to stormwater runoff at the site and can cause the same impacts unless properly managed. You may discharge clean, non-turbid de-watering, such as well-point ground water, to systems that are tributaries to, or directly into, surface waters if the de- watering flow does not cause erosion or flooding or interfere with the operation of the stormwater system. Use the following BMPs: • C220 Storm Drain Inlet Protection • C236 Vegetative Filtration Maintain BMPs (not shown) All temporary and permanent erosion and sediment control BMPs must be maintained and repaired as needed to assure continued performance of their intended function. During the dry season, inspect sediment control BMPs weekly or after a runoff-producing storm event. During the wet season, inspect BMPs daily. Use BMP C150 Materials on Hand to ensure you are ready for a heavy rain. All temporary erosion and sediment control BMPs must be removed within 30 days after the City determines that the site is stabilized or after the temporary BMPs are no longer needed. Trapped sediment must be removed or stabilized on site. Disturbed soil areas resulting from removal of BMPs or vegetation must be permanently stabilized. Manage the Project (not shown) Phasing a project, especially when revegetation occurs as part of each phase, can help prevent the transport of sediment from the site. • Fully implement this Construction SWPPP at all times. • Modify this Construction SWPPP whenever there is a change in 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. • Inspect, maintain, and repair all BMPs as needed to ensure continued performance of their intended function. 8 9 10 11 12 page 5 of 5 Protect Low-Impact Development BMPs Low-Impact Development techniques can be damaged if they are compacted or accumulate sediment during construction. If there are any Low-Impact Development BMPs planned for the site: • Use BMP C103 High Visibility Fence to exclude all construction and foot traffic from the infiltration, bio- retention, or rain garden areas. • Protect all infiltration areas or bio-retention and rain garden BMPs from sedimentation through installation and maintenance of erosion and sediment control BMPs on portions of the site that drain into those areas. • Use BMP C233 Silt Fence or C234 Vegetated Strip to control and avoid introducing sediment onto permeable pavements. Bury the bottom of the filter fabric at least 4 inches below the ground surface. Backfill and tamp soil in place over the buried portion of the filter fabric, so that no flow can pass beneath the fence and scouring cannot occur. Drive or place the fence posts into the ground at least 18 inches. A 12-inch minimum depth is allowed if topsoil or other soft subgrade soil is not present and 18 inches cannot be reached. • If pavements are fouled with sediments or no longer pass an initial infiltration test, clean them using procedures from the Stormwater Manual or the manufacturer’s procedures. Consider the following additional BMPs: • C102 Buffer Zones • C208 Triangular Silt Dike • C231 Brush Barries **************************************************************** I acknowledge that I have read the information presented to me and agree to abide by the BMP rules. _CAMERON RUTH______ _____________________ Printed name Signature __MARCH 27, 2024_______________ Date **************************************************************** 13 Eastside Environmental Pros 15 November 2023 EE-383 Cameron Ruth Via email: cam.ruth@gmail.com REFERENCE: City of Anacortes Parcel P110565 SUBJECT: Critical Areas Report Dear Cameron, At your request, Eastside Environmental Pros has investigated your property (hereinafter referred to as “Site”) and areas within 300 feet of the Site for the presence of critical areas (i.e. wetlands and streams). The property and surrounding 300 feet are referred to jointly as the “Study Area”. This report has been prepared to comply with the requirements of the Anacortes Municipal Code (AMC) §19.70.115- Critical areas report. PROPERTY LOCATION The Site is a single 0.17-acre tax parcel (P110565) located at 2315 24th Street in the City of Anacortes. The Public Land Survey System location of the Site is the Southwestern quarter of Section 24, Township 35 North, Range 01 East, of the Willamette Meridian. PROPERTY DESCRIPTION AND LAND USE The Site is bound to the south, east, and west by developed single-family residences, and to the north by 24th Street. The Site contains a single-family residence, a driveway. Vegetation onsite consists of maintained lawn and ornamental species. Topography onsite is relatively flat with an approximate elevation of 260 feet. METHODOLOGY The Study Area was evaluated for the presence of critical areas on 26 October 2023 using the routine approach described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (U.S. Army Corps of Engineers, 2010). Offsite areas were evaluated from what could be observed visually from the boundary of the Site, public rights-of-way, and via agency databases. Attachment 1 contains wetland determination datasheets prepared by Eastside Environmental Pros for representative locations within the Site. Attachment 2 contains wetland rating forms. Photos are located at the end of the report, before the figures section. ONSITE INVESTIGATION RESULTS One (1) wetland (Wetland A) was identified offsite approximately 200 feet away during the 26 October 2023 Site evaluation (Figure 1). No other critical areas were identified within the Study Area. WETLAND A Wetland A is an approximately 45,649-sf (1.05 acre) wetland and is located approximately 200 feet to the west of the Site beyond two single-family residences. Wetland A has a depressional hydrogeomorphic (HGM) classification (Brinson, 1993), and palustrine forested Cowardin classification (Cowardin et al., 1979). Wetland A is a Wetland of High Conservation Value which categorizes it as a Category I wetland. Category I wetlands with a habitat score of 6 in high intensity land use areas have a standard 150- foot buffer plus a 10-foot building setback per AMC §19.70.235 and §19.70.235.L. SUMMARY The applicant proposes to construct a detached dwelling unit in the southern portion of the Site. No critical areas were identified onsite during the 27 October 2023 Site evaluation. One wetland (Wetland A) was identified offsite but within the Study Area approximately 200 feet to the west of the Site boundary. The buffer of Wetland A does not extend to the property and therefore no impacts are proposed as part of this project. We trust that the information presented here sufficiently describes and documents critical areas on your property.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. NO – go to 6 YES – The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding Wetland name or number Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fish and wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to variation caused by disturbance, changes in season and weather, and other factors. WDFW does not recommend using reports more than six months old.
