Geologically Hazardous Areas A response and revised geotechnical report remains outstanding for the Interplast NW single family project.The peer review for the geotechnical portion will require a$1,000.00 deposit to review any revisions, no test pits were performed on site. As the report does only provide an assessment of the GHAs the city may require additional report requirements including subsurface explorations and foundation design and earthwork recommendation as the site is mapped by the city as a critical area. A reminder letter,complete with all outstanding city comments will be forwarded shortly. Wetland Delineation Overall,as proposed the wetland evaluated under the Shoreline critical areas code resulting in an incorrect buffer width and wetland category. The wetland on your site is a part of a larger wetland complex and thus rated the same throughout with the same wetland buffer width. Dual rated wetlands are quite uncommon. Becky Chapin my colleague reviewed the Adzhigirey residence. Perteet concurred with the applicant's biologist OS Jones)that the wetland is a Category II wetland with a 100 ft. buffer(Palustrine Scrub/shrub—Forested wetland) under the city's previous critical areas code,the code was updated in June 2015. Perteet is also the city's consultant on this project. Process III-Reasonable Use Your proposal will require a Process III 'Project Approval'for'reasonable use of the subject property'in order to intrude into the wetland buffer before approval of a residential building permit. The intrusion would need be limited to a 1,600 sf residence footprint and likely a redesign of the home plans already submitted (reduction of total impervious surface, driveway, patio areas and walkways, likely not a three car garage etc.). Please find an attached Adzihgirey Critical Areas review letter attached from the Planning Division. Let me know if you have any questions.
