Section 1, second from the last paragraph — Include that this site qualifies as a Large Site Project per ECDC Chapter 18.30. RESPONSE: Added to report where indicated. 2. Section 3 — This section properly lists the minimum requirements applicable to the project. The reviewer could not find discussions on how the project complies with minimum requirement #3 (Source Control of Polltion) and minimum, requirement #8 (Wetland Protection). Please include. I RESPONSE: The site does not discharge directly or indirectly into a wetland., so i-niniMMI-1 requirement #8 does not appear to be applicable. This is discussed in Chapter 4 of the report, Source Control is discussed in Chapter 6. 3. Section 5, A & B — Indicate that based on the geotechnical study, the site will be modeled in WWHM using Type C soils. RESPONSE: Added to noted parts of report. CARLEM ARCHITECTS, P.S. Jeanie McConnell July 16, 2014 Page 3 of 10 4. Section 5, C & E — The site is located within the Halls Creels drainage basin, making part of the Greater Lake Ballinger Watershed (Edmonds StormlVater Code Supplement [ESCS] page 51). Consequently per ESCS Section 5.6.2.2, phosphorus treatment of the runoff from the pollution generating impervious surface is required. The designer can choose from those treatment technologies in the 2005 or 2012 Ecology Storinwater Management Manual for Western Rashington or the phosphorus treatment technologies approved by Ecology with a General Use Level designation (http://www.ecy.wa.yov/programs/wq/stormwater/newtech/teclu-iolovies.html). The most common of these technologies used in Edmonds are the Mistar Flogard Perls Filter (low head requirement) and the Americast Filterra units (Note: the City is not endorsing the use of these products, just providing some potential options that will meet the regulatory requirements.). The same "pretreatment" requirements apply to these'technologies that apply to the Contech stormfrlters that are included in the current design. RESPONSE: Perls Filters by Kristar have been implemented into the design in }dace of the Storrmilters. Section 5E — Include the WWHM reports for sizing the water quality treatment system. RESPONSE: Added to report. 6. Section 5F— Show that the riser. pipe that is part of the detention system control structure can handle the 100 year un -detained flow (1.16 cfs). A SPONSE: Discussion of the overflow capacity added to this section. 7. Section 6 — Since the site is classifies as a Large Site project, it is subject to the requirements in Appendix I of the City's stormwater discharge permit with Ecology. While most of the requirements have been addressed, the City requires the applicant fill out the Permit Appendix 7 (Construction Site Sediment Damage Potential Worksheet, enclosed). This form helps the City's inspectors plan for the frequency of inspection during construction. Please include a filled out worksheet in the report. RESPONSE: This worksheet is added to Section 6. It does not appear that any of the -erosion sensitive features denoted in Step 1 are applicable. If none of these features apply, Step 1. indicates the assessment to be complete. Plan Sheets 8. Sheet C3.1 CBs 6 and S (water quality treatment) should reference details on the configuration of the treatment system (usually the manufacturer's detail for the specified .products(s)) RESPONSE: Details added (Sheet C3.3) CARLETTI ARCHITECTS, P.S.
