y' Sabrina Fandler -� City of Everett Public Works Engineering / Permit Services Division -2-) February 15, 2017 i. Transmittal Sheet: (1) available online at https.Ileverettwa.gov/Permits or at the Permit Counter-2nd Floor, 3200 Cedar Street. if Plans: (4) sets of revised plans plus original City Markups. N. A Hold Harmless agreement will likely be required. The City will work on the language and forward to the applicant/owner for signature if required. Response: A completed transmittal sheet along with the revised civil engineering plans and associated documents and a copy of the comment letter provided by the City are included in this package. The Permit Counter is open Monday through Friday from 7..30am- 12. OOpm and from 1:00pm- 4:00pm (closed between 12.00pm-1:00pm for lunch). 2. The comments below were generated from this project's Stormwater Reviewer. If you have any questions regarding these comments, please contact Jane Zimmerman with the City of Everett Public Works Department (425-257-8885 or JZimmerman @everettwa.gov). a. On Sheet C-6, within the Geotechnical Notes, any time the note says "Should" must be replaced with the work "Shall" See attached scan (notes # 2, 14, 15, 16.) Response: All instances of the word "should" have been changed to "shall" within the geotechnical notes. b. The below comments were issued in the last round of review, but were not adequately addressed. Please see the comments including the attached highlighted sections. All sections must be adequately addressed in revisions that are turned in to the City. Please see the first attachment for the general design criteria from the City's 2010 Stormwater Management Manual (SWMM) (Chapter 2, Volume Ill) that have not yet been met for the design of the stormwater control pond on this site. l have printed out the appropriate pages and highlighted the criteria that haven't been met. In my opinion, the City's general design criteria for flow control and treatment BMPs are the least stringent criteria that must be met to ensure the safety of the stormwater control facility at this location. All parts of the City's Stormwater Management Manual must be met to be in compliance with City Standards and for the City to be able to issue a permit. Please pay particular attention to the highlighted elements for specific criteria that need to be addressed on the plans in the resubmit/al. Response: This attachment was referenced and it is our understanding that we have met these criteria with the redesign of the detention pond and additional slope stability analysis from the geotechnical engineer. In particular, please carefully follow section 2.11 Setbacks of the 2010 Stormwater Management Manual. Item 1.c. lists that in no case shall the setback from the steep slope be less than the vertical height of the slope. This must be stringently followed. A generous look at the steep slope indicates that the vertical height of the steep slope is between 90 and 100. This means that the setback from the top of the steep slope for any construction (retaining wall, stormwater
