On March 25, 2021, Confluence conducted a site visit on the property to determine the presence and extent of critical areas on and adjacent to the property. The effort focused on streams. Note that no visual indicators of wetlands were observed during the site visit and therefore a wetland delineation was not performed. Critical areas such as erosion hazard areas, steep slopes, and landslide hazard areas were not evaluated in this study. Per Edmonds Community Development Code (ECDC) Chapter 23, the project is located in a Fish and Wildlife Habitat Conservation Area (FWHCA). This report has been prepared pursuant to the special study and report requirements of ECDC Chapter 23.90.020. The project site ("the property') is currently developed with a single-family residence, a paved driveway, and maintained lawn areas. Shell Creek flows north along the western property boundary. The property is zoned as RS-6 (residential, minimum lot area 6,000 square feet) and is surrounded by other single-family residences (City of Edmonds 2021).

This section describes the methods used to delineate the OHWM. 2.1 Desktop Analysis Confluence evaluated the parcel for the presence of critical areas by reviewing the following available GIS databases: ■ City of Edmonds GIS (City of Edmonds 2021), ■ Snohomish County PDS Mapper (Snohomish County 2021), ■ U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (USFWS 2021), ■ National Resource Conservation Service (NRCS) Soil Survey (NRCS 2021), ■ Washington Department of Fish and Wildlife (WDFW) SalmonScape (WDFW 2021a), ■ WDFW Priority Habitat and Species (PHS) (WDFW 2021b), ■ Washington Department of Natural Resources (WDNR) Water Type GIS (WDNR 2021 a), and ■ WDNR Wetlands of High Conservation Value (WDNR 2021b) Results of the GIS database searches are in Appendix A. 2.2 Ordinary High Water Mark Delineation The Washington State Code defines the OHWM as "on all lakes, streams, and tidal water is that mark that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from that of the abutting upland, in respect to vegetation as that condition exists on June 1, 1971, as it may naturally change thereafter, or as it may change thereafter in accordance with permits issued by a local government or the department" (RCW 90.58.030). Washington State Department of Ecology (DOE) has published a guide (Anderson et al. 2016) to interpret the code and provide guidance for field OHWM determinations. Confluence used this guidance to determine the OHWM of Shell Creek in the vicinity of the property. Confluence identified discrete locations on the bank of the stream to delineate the OHWM. Locations were chosen based on presence of field indicators of OHWM identified in Anderson et al. (2016) and shape of the channel. The location of the OHWMs within the property were recorded using a differential GPS with sub -meter accuracy. April 2021 Page 3 817 Th Avenue North Critical Areas Study 3.0 RESULTS This section describes the results of the OHWM delineation. 3.1 General Site Description CONFLUENCE ENVIRONMENTAL COMPANY Available GIS databases were searched for the documented presence of wetlands, hydric soils, streams, lakes, or species listed under the Endangered Species Act (ESA) as threatened or endangered ("listed species"). Results of the GIS databases searched are in Appendix A. A perennial, Type F (fish -bearing) stream known as Shell Creek is located along the western property boundary and flows north toward Puget Sound (WDNR 2021a). The headwaters of Shell Creek are located approximately 1.5 miles southeast of the property in Pine Ridge Park in a large wetland (USFWS 2021). Shell Creek eventually outlets into Puget Sound approximately 0.3 mile north of the property. WDFW's SalmonScape shows the documented presence of coho (Oncorhynchus kisutch) within the portion of Shell Creek just north of the property. The remainder of Shell Creek is mapped as gradient accessible for coho. Only 1 partial fish passage barrier is mapped by WDFW's SalmonScape, meaning coho presence is likely in the entire creek (WDFW 2021a). Snohomish County's remote sensing -based wetland model shows a large wetland along the banks of Shell Creek between the point at which the creek crosses 7th Avenue North to where it outlets into Puget Sound (Snohomish County 2021). USFWS's NWI does not map any wetlands on or within the vicinity of the property (USFWS 2021). No wetlands of high conservation value are mapped on or within the vicinity of the property (WDNR 2021b). Soils are mapped as Alderwood-Urban land complex (2-8% slopes) - a nonhydric soil (NRCS 2021). WDFW's PHS mapping tool identifies resident coastal cutthroat trout (Oncorynchus clarkii) within Shell Creek (WDFW 2021b). This species does not have status under the ESA. Photographs of the property are in Appendix B. 3.2 Shell Creek Shell Creek is located on the property. Several sources (i.e., WDNR 2021a, WDFW 2021A, WDFW 2021b, USFWS 2021, City of Edmonds 2021, Snohomish County 2021) map Shell Creek flowing through the property. As is described in Section 3.1, Shell Creek is a Type F stream, with documented salmonid presence (WDNR 2021a, WDFW 2021a, WDFW 2021b). Shell Creek begins within Pine Ridge Park within a large wetland approximately 1.5 miles southeast of the property and discharges into Puget Sound approximately 0.3 mile north of the property. During the site visit, the OHWM was delineated on the property and is shown in Figure 2. Within the property, the right (east) bank of Shell Creek is mostly armored with riprap (shown in photo #1 in Appendix B), while the left (west) bank is less defined and consists of some April 2021 Page 4 817 Th Avenue North Critical Areas Study CONFLUENCE ENVIRONMENTAL COMPANY cobbles and a gradual slope up to the tree line. A wooden footbridge is positioned over Shell Creek on the property. A drainage feature is located adjacent to the right bank (shown in photo #3 in Appendix B). This man-made feature contains concrete sidewalls and directs flow into Shell Creek. While unconfirmed, the source of the water flowing into the drainage feature is likely stormwater runoff from 7f Avenue North. The primary indicators used to delineate the OHWM included top of bank and darker stains on fixed objects such as riprap. 4.0 HABITAT ASSESSMENT This section evaluates the habitat of the fish and wildlife conservation area located on the property. 4.1 Vegetation Both banks of Shell Creek are largely unvegetated and consist of bare ground (shown in Photo #1 in Appendix B). Four trees, including western red -cedar (Thuja plicata) and an unidentified non-native species, are located approximately 10 feet from the right (east) bank. There are 4 large conifers on the west side of the stream. No overhanging shrubby vegetation is present along the banks. The remainder of the 100-foot buffer between the house and the stream consists of lawn and 3 large conifers (2 Douglas -fir [Pseudotsuga menziesii] and 1 ornamental, non-native tree). The relative lack of riparian vegetation is indicative of a low -functioning stream buffer. Riparian vegetation is essential in providing shade for salmonids and other resident fish, erosion reduction, a source of large woody debris which increases habitat complexity within the stream, vital nutrients from associated organic matter, and a food source for aquatic and terrestrial insects that feed on such organic matter (Knight 2009). These functions are largely absent within the stream buffer in its current condition within the property 4.2 Species of Local Importance and Priority Species WDFW's PHS mapping tool identifies resident coastal cutthroat trout within Shell Creek (WDFW 2021b). This species does not have status under the ESA. 4.2.1 Management Recommendations WDFW's 2009 land use guide for salmon, steelhead, and trout outlines important salmonid habitat elements and management recommendations related to land use changes (Knight 2009). The salmonid habitat elements relevant to this project include stormwater runoff and riparian areas. Stormwater management recommendations include adhering to the local stormwater management manual and using low -impact development methods such as limiting impervious surfaces and utilizing rainwater on -site. Riparian areas management recommendations include April 2021 Page 5 817 Th Avenue North Critical Areas Study CONFLUENCE ENVIRONMENTAL COMPANY protecting and restoring the natural streambank and designating natural buffers based on best available science (Knight 2009). This project will follow WDFW riparian management recommendations. 4.3 Functional Assessment The habitat adjacent to the proposed project consists of a residential yard with a maintained lawn. A total of 11 trees, including Douglas -fir, western red -cedar, and ornamental, non-native trees, are located on the property. As is described in Section 3.2, Shell Creek flows north along the western property boundary. The streambanks are mostly unvegetated and consist primarily of bare ground. The right (east) bank has been modified and is armored with riprap, while the left (west) bank consists of some cobbles and a gradual slope up to the tree line. Downstream of the property, the banks of Shell Creek appear to be in similar condition as observed on -site (i.e., armored with riprap). Several adjacent single-family residences appear to abut the stream both upstream and downstream of the property. 4.3.1 Stream The stream functions of Shell Creek have been impacted by residential development along its entire watershed. The following stream functions were evaluated: ■ Flow regime - Flow regime is influenced by the surrounding impervious surface of the watershed. The banks are confined by armoring. The project site consists of a single- family residence and large lawn. ■ Water quality - Water quality is consistent with an urbanized environment. Shell Creek is not on the DOE 303(d) list for impaired waters (Ecology 2021). ■ Sediment and organic material input - The substrate consisted of sand and medium- sized cobbles. Sediment sources are limited due to development. In its current condition, the stream is impacted by residential development and provides limited habitat. 4.3.2 Buffer Within the project area, the stream buffer consists of unvegetated bare ground in the immediate vicinity of Shell Creek, 4 conifers approximately 10 feet from the right (east) bank, 4 conifers on the left (west) bank, and a large lawn with 3 conifers. The following stream buffer functions were evaluated: ■ Large Woody Debris (QM - There is little potential for LWD recruitment. If one of the large trees were to fall, it would impede upon the use of the property or impact the neighboring house or property. Any tree that falls would likely be removed. April 2021 Page 6 817 Th Avenue North Critical Areas Study CONFLUENCE ENVIRONMENTAL COMPANY Organic matter recruitment - There is potential for recruitment from falling branches in the buffer. There are no shrubs present within the buffer and the majority of the buffer is lawn. This function is poor in the project area. ■ Temperature maintenance - The large trees adjacent to the stream provide good shading. The other 3 trees in the yard do not provide any additional shading functions. ■ Pollution assimilation -The stream receives stormwater inputs and other sources of pollution typical of an urbanized environment. There is approximately 100 feet of lawn that could provide some amount of pollution assimilation. However, the buffer does not contain any wetlands or other features with the ability to effectively assimilate pollution or provide flood storage. ■ Streambank stabilization - The existing streambank is mostly artificially armored and does not have a natural streambank component. The banks are unvegetated. ■ Sediments and nutrients - The buffer on -site provides limited sources for sediment and nutrients. The banks are armored to prevent any scour and the buffer lacks vegetation. 4.4 Proposed Condition The proposal is to construct a second -story deck on posts approximately 92 feet from Shell Creek. ■ There will be no loss of riparian vegetation. No vegetation will be removed for this project. The deck will be on the second story with posts. The ground beneath the deck currently consists of bare dirt and lawn. Disturbance will be minimized to the installation of several posts. ■ There will be no addition of impervious surfaces. The deck will allow for water to penetrate between the planks. ■ The existing functions of the FWHCA located on the property will not be impacted by this project. 5.0 REGULATORY IMPLICATIONS According to ECDC 23.90 (for FWHCAs), the following standard buffers apply: ■ Shell Creek, a Type F stream, has a standard buffer of 100 feet. o The creek is approximately 107 feet away from the house and the proposed deck will extend 15 feet from the house, meaning the deck will encroach approximately 8 feet into the stream buffer. o Mitigation is not proposed because the project (described above in Section 4.4) will not degrade the quantitative or qualitative functions and values of the FWHCA (per ECDC 23.90.030), which is based on the existing stream buffer condition and the lack of ground disturbance/addition of impervious surface area associated with the project. The proposed project is also in accordance with WDFW's management April 2021 Page 7 817 Th Avenue North Critical Areas Study CONFLUENCE ENVIRONMENTAL COMPANY recommendations for protecting salmonid habitat (Knight 2009) because no impacts to the stream buffer functions described in Section 4.3.2 are proposed. Figure 2 shows Shell Creek, the OHWM delineation, and the standard stream buffer. Development within this buffer or within the critical area itself requires compliance with ECDC 23.90 - Fish and Wildlife Habitat Conservation Areas.
