The proposed project for the Motson’s by Simon Little Studio STL includes relocating an existing house (1,104sqft) and building a new home (1,465 sqft) in the same footprint. The history of this site includes a previous report for the Underwoods (January 2007, Olympic Wetland Resources. Inc.) that was required prior to upgrading an existing septic system. Findings from the 2007 report documented that the wetland fell in the valley bottom and was not adjacent to the western property boundaries as indicated on the Jefferson County Critical Areas Map. Measurements from the 2007 assessment indicated the existing homesite measured ~120 feet from the western property boundary defined by a fence. Chimacum Valley, associated with Chimacum Creek downslope is on private property. The exact wetland edge was not delineated during the 2007 assessment. From knowledge of known plant association, it appears wetland vegetation consisting mostly of grasses, sedges, or rushes are 50’ or more downslope and confined to the valley bottom. The site was revisited with Simon Little and property owners on June 28, 2021. No report was produced from this site visit. Field book notes and site measurements were consulted for this report. Original measurement from 2007 were confirmed; the existing house is 119’ from the western property boundary defined by the fence. The wetland appears to be at least 50 feet or more to the west and confined to the valley bottom on private property. The Jefferson County Critical Areas Map is incorrect. Findings were confirmed using professional judgement. The site visit included a visual assessment of plant community (mostly grasses), aerial maps (wetland vegetation has a color change), and topographic analysis. This parcel is approximately 80 feet in elevation above Chimacum Creek which has been channeled. Maps consulted include both the Jefferson County Critical Areas Map and Google aerial maps. I would be happy to provide additional environmental information on request.

Hitchcock vegetation update 2018 Olympic Wetland Resources, Inc. Dixie Llewellin, Principal Biologist A Level Beverly Areas Map the Beaver Valley. The project is to upgrade the existing septic system to service a single family residence. This wetland assessment is required to determine the distance the proposed septic is from the wetland. Future goals are to build a single-family residence within the footprint of an existing home. Description of Site Legal Description: Parcel #821 063006 Section 6 Township 28N Range IE Location: 3895 Beaver Valley Road (SR 19), Jefferson County Soils: Arne Alderwood gravelly loam Slopes: 0 to 15% slopes According to the National Wetland Inventory Maps the wetland has been categorized as PUBHx Palustrine Unconsolidated Bottom Permanently Flooded excavated). The wetland connects with a larger wetland system associated with Beaver Valley. These wetlands on the eastern side of Chimacum Creek consist mostly of agricultural land and do not have high habitat value or wetland functions due to the lack and structural layers or diversity. The subject property slopes gently to the west and adjoins farmland that is along Chimacum Creek. Currently the adjacent parcel is fenced and has grazing sheep. Large piles of debris were present on site from clearing blackberries and demolishing old buildings. Soils were saturated from the exceptionally high rainfall that that is occurring this winter. The soils on the subject parcel however, did not meet the hydric soils criteria. Levell Assessment Underwood Report File Number 2007- 0201 1 Olympic Wetland Resources, Inc. 01/07 Findings The subject parcel is outside of the wetland, however the neighboring parcel was fenced so it was not possible to accurately determine the distance from the wetland edge to the boundary of the subject parcel. Using the Department of Ecology (DOE) Wetland Field Data Form this wetland rates as a high- quality Category II wetland (23 points). All Category II wetlands receive protective buffers of 150 feet if the wetland is not delineated and 100 feet if the wetland is delineated. Enclosed is the Wetland Rating Form. The proposed septic site location, as designed by John Scott Fleming Engineering, Inc. is outside all wetland buffers restrictions. The proposed septic location is not only upslope from the Category II wetland but over 150 feet from a wetland edge (Table 3-3 Minimum Wetland Buffers Necessary as part of Qualifying for a Waver from Delineation and Special Report Requirements, Section 3 Wetlands UDC). Please find the enclosed Level I Assessment Map with field findings. This map does NOT represent a formal delineation. During the clearing of the site (mostly invasive Himalayan blackberries and old out buildings) an unmapped stream was uncovered. The stream had a significant flow of stormwater during this site visit. Although the stream has not been mapped or classified, it will either be a Type 4 or 5 with associated buffers of 100 to 50 feet respectively. Ross Goodwin, Department of Natural Resources 360 732-7175) should be contacted to determine the classification of this stream. The old homesite is likely within the stream buffer and possibly within the undelineated wetland buffers. The new single family residence may be grandfathered if it is within the exact footprint of the existing structure. It should be noted that the wetland below the Underwood parcel was not ponded as was much of Beaver Valley during these rains. Land use restrictions may apply to all future building developments associated with this parcel. Final authority over wetland determinations and associated buffers rests with Jefferson County Department of Community Development. If this project requires delineation or if you have further planning needs please don't hesitate to call. Sincerely, Dixie Llewellin Principal Biologist, Olympic Wetland Resources, Inc.
