[CS 208.1] - Enclosures (with roof) shall be required for all new commercial and redevelopment projects where Minimum Requirement #1 though #5 or Minimum Requirement #1 though #9 are required, as outlined in the Ecology Manual. Enclosures shall be covered (roof) and fully enclosed to prevent precipitation from entering containers, compactors, grease traps and the enclosure floor. This does not exempt the requirement for watertight containers. - Enclosures shall be large enough for a garbage service vehicle to pick up and dump the waste without the container being rolled outside the enclosure. Total height of the enclosure shall be a minimum of 15 feet. The gate opening shall be a minimum of 12 feet wide and swing open a minimum of 90 degrees from the - closed position.

STORMWATER/ EROSION CONTROL: • Refer to City Standards, Section 200 for Stormwater System Requirements. [PMC 17.42] • Stormwater design shall be in accordance with PMC Chapter 21.10 and the current stormwater management manual as adopted by the City Council at the time of project application. The City is currently using the 2019 Department of Ecology (Ecology) Stormwater Management Manual for Western Washington (aka “Ecology Manual”). • The applicant shall complete the stormwater flowchart, Figure 1-3.1 and Figure 1-3.2, contained in the Ecology Manual. The completed flowchart shall be submitted with each stormwater site plan submittal and highlight the Minimum Requirements (MR) triggered by the project thresholds. • The project proposes a direct discharge connection to the Puyallup River. The downstream conveyance system shall be verified in accordance with the requirements of PMC 21.10.04 and the Ecology Manual, Volume I, Section 3.4.7 and City Standards Section 204.2. Specifically: - The project site must be drained by a conveyance system that is comprised entirely of manmade elements and extends to the ordinary high water mark of the Puyallup River; - The conveyance system between the project site and the Puyallup River shall have adequate conveyance capacity to convey discharges from the proposed (post-development) project, in addition to the discharges associated with the existing basin tributary to the outfall; - All such flows shall remain within all catch basin or manhole rims for a continuous model simulation associated with the September 17, 1969, storm event assuming no backflow influence from the Puyallup River and shall provide greater than one cfs remaining capacity of the system. - The discharge will not cause, or aggravate, downstream flooding problems - The discharge does not reduce natural flows to other streams or wetlands • The preliminary storm report indicated the use of bioretention (raingardens are not appropriate for commercial projects) to process roof runoff. This is confusing due to the bioretention facility containing an underdrain and roof runoff generally does not require treatment. If the design intent is to infiltrate roof runoff using LID BMPs, then wet season groundwater monitoring and infiltration testing will be required at the location of any individual BMP. The number of infiltration tests shall be based on the area contributing to the proposed facility/BMP, e.g., one test for every 5,000 sq. ft of permeable pavement, or one test for each bioretention cell. • If applicable, preliminary feasibility/infeasibility testing for infiltration facilities/BMPs shall be in accordance with the site analysis requirements of the Ecology Manual, Volume III, Chapter 3, specifically: - Groundwater evaluation, either instantaneous (MR1-5), or continuous monitoring (MR1-9), during the wet weather months (December 1 through April 30). - Hydraulic conductivity testing: i. If the development meets the threshold to require implementation of Minimum Requirement #7 (flow control); or, if the site soils are consolidated; or, if the property is encumbered by a critical area, then Small Scale Pilot Infiltration Testing (PIT) during the wet weather months (October 1 through April 1) is required. - Testing to determine the hydraulic restriction layer. - Mounding analysis may be required in accordance with Ecology Volume V Section V-5.4. • Upon submission of any geotechnical infiltration testing, appropriate long-term correction factors shall be noted for any areas utilizing infiltration into the underlying native soils in accordance with the Ecology Manual, Volume III, Chapter 3. Provide the long-term infiltration rate calculation in the stormwater report. • At the time of civil permit application, the applicant is responsible for submitting a permanent storm water management plan which meets the design requirements provided by PMC Section 21.10. [PMC 21.10.190, 21.10.060] - When using WWHM for analysis, provide the following WWHM project files with the civil permit application: - Binary project file (WHM file extension) - ASCII project file (WH2 file extension) - WDM file (WDM file extension) - WWHM report text (Word file) • Water quality treatment of stormwater shall be in accordance with the Ecology Manual, Volume 1, Minimum Requirement 6; and Volume 5, Runoff Treatment. • If the final design includes the use of bioretention cells for water quality treatment, the following notes shall be added to the civil design plans: - “At the completion of the bioretention cells construction, the engineer-of-record shall provide a written statement to the City of Puyallup that the bioretention cells were built per the approved design.” - “The bioretention soil media (BSM) supplier shall certify in writing that the bioretention soil media meets the guidelines for Ecology-approved BSM including mineral aggregate gradation, compost guidelines, and mix standards as specified in the 2012 Low Impact Development Technical Guidance Manual for Puget Sound. And, if so verified, no laboratory infiltration testing, cation exchange, or organic content testing is required.” • At the time of civil permit application, all pipe reaches shall be summarized in a Conveyance Table containing the following minimum information and included in the TIR: Pipe Reach Name Design Flow (cfs) Structure Tributary Area Pipe-Full Flow (cfs) Pipe Diameter (in) Water Depth at Design Flow (in) Pipe Length (ft) Critical Depth (in) Pipe Slope (%) Velocity at Design Flow (fps) Manning’s Coefficient (n) Velocity at Pipe-Full Flow (fps) Percent full at Design Flow (%) HGL for each Pipe Reach (elev) • All storm drains shall be signed as follows: a) Publicly maintained stormwater catch basins shall be signed using glue-down markers supplied by the City and installed by the project proponent. b) Privately maintained stormwater catch basins shall be signed with pre-cut 90ml torch down heavy-duty, intersection-grade preformed thermoplastic pavement marking material. It shall read either “Only Rain Down the Drain" or “No Dumping, Drains to Stream”. Alternatively, the glue-down markers may be purchased from the City for a nominal fee. • All private storm drainage facilities shall be covered by a maintenance agreement provided by the City and recorded with Pierce County. The BMP descriptions and maintenance criteria shall be obtained from the "City of Puyallup Site Management Plan for Stormwater Operations and Maintenance" which is available on the City’s website. Under this agreement, if the owner fails to properly maintain the facilities, the City, after giving the owner notice, may perform necessary maintenance at the owner’s expense. • Prior to permit issuance, the applicant shall post a financial guarantee in accordance with PMC 21.10.160 in the amount of 125% of the cost of the stormwater system. • A Stormwater Systems Development fee will be assessed for each new equivalent service unit (ESU) in accordance with PMC Chapter 14.26. Each ESU is equal to 2,800 square feet of ‘hard’ surface. The current SDC as of this writing is $4,013.00 per ESU. • Stormwater Systems Development fees are due at the time of site development permit or in the case where no site development permit is required, at the time of building permit issuance for the individual lot(s); and the fees do not vest until the time of site development permit issuance, or at the time of building permit issuance in the case where a site development permit is not required. • A Construction Stormwater General Permit shall be obtained from the Department of Ecology if any land disturbing activities such as clearing, grading, excavating and/or demolition will disturb one or more acres of land, or are part of larger common plan of development or sale that will ultimately disturb one or more acres of land.
