Development and redevelopment projects are required to employ, wherever feasible, Low Impact Development (LID) Best Management Practices (BMPs) to meet the design criteria set forth in PMC 21.10.190, the Ecology Manual Volume I, Minimum Requirement 5; Volume III, Chapter 3; and Volume V, Chapter 5. 39. Preliminary feasibility/infeasibility testing for infiltration facilities/BMPs shall be in accordance with the site analysis requirements of the Ecology Manual, Volume I, Chapter 3, specifically: - Groundwater evaluation, either instantaneous (MR1-5), or continuous monitoring (MR1-9), during the wet weather months (December 21 through April 1). - 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 (December 21 through April 1) is required. ii. If the development does not meet the threshold to require implementation of Minimum Requirement #7; or, is not encumbered by a critical area; and is located on soils unconsolidated by glacial advance, grain size analyses may be substituted for the Small Scale PIT test at the discretion of the review engineer. - Testing to determine the hydraulic restriction layer. - Mounding analysis may be required in accordance with Ecology Volume III Section 3.3.8. 40.

This facility was designed and constructed to past stormwater regulations using a single event model, Santa Barbara Urban Hydrograph (SBUH) for flow control, and a wetpool sized using ½ of the 2-yr release rate for water quality compliance. - The applicant shall provide supporting documentation substantiating the 2-yr, 10-yr, and 100-yr release rates of the existing detention facility. - The upstream basins tributary to the existing detention facility shall be incorporated into the current project’s stormwater model in such a way as to ensure no increase in flow (release rate) to the downstream stormwater system post-project while complying with the requirements of the Ecology Manual for the proposed project. - The applicant shall provide water quality facilities for the existing upstream basins equal to, or better, than the existing wetpool facility to ensure no degradation of stormwater from the properties to the South. - Provide a detailed explanation of the analysis in the written technical report, including, but not limited to, assumptions; calculations; discharge rates; stage-storage relationships; recommendations, and any proposed modifications to the existing system. 46. Overflow facilities shall be provided at the low points of the proposed permeable pavement areas to allow safe discharge to the downstream public storm system. 47. The use of permeable pavement(s) will require trench dams where utility pipes cross property lines. 48.

And, if so verified, no laboratory infiltration testing, cation exchange, or organic content testing is required.” 54. Construction of frontage improvements associated with this project will require installation/extension of the stormwater main to accommodate road runoff. The new stormwater main shall be adequately sized to accommodate any upstream basins tributary to main. 55.

All private storm drainage facilities shall be covered by a maintenance agreement provided by the City and recorded with Pierce County. 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. 60. Erosion control measures for this site will be critical. A comprehensive erosion control plan will be required as part of the civil permit application. 61. 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. 62. 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. 63. 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.
