CITY OF PUYALLUP PERMITTING PORTAL

Other/Miscellaneous

CIVIL PERMIT APPLICATION • Civil engineering drawings will be required for this project if the proposed parking stalls propose 2,000SF or more of new plus replaced hard surfaces. (Note: The city has transitioned to electronic review. Please reach out to the city permit technicians at PermitCenter@PuyallupWA.gov and they will guide you as to how to submit). Included within the civil design package will be a utility plan overlaid with the landscape architects landscaping design to ensure that potential conflicts between the two designs have been addressed. • Engineering plans cannot be accepted until Planning Department requirements have been satisfied, including but not limited to, SEPA, Preliminary Site Plan approval, CUP, and/or Hearing Examiner conditions. • Civil Engineering plan review fee is $670.00 (plus an additional $130.00 per hour for reviews in excess of five hours). The civil permit shall be $300.00, and the inspection fee shall be 3% of the total cost of the project as calculated on the Engineering Division Cost Estimating Form. [City of Puyallup Resolution No.2098] • Civil Engineering drawings shall conform to the following City Standards Sections 1.0 and 2.0: o Engineering plans submitted for review and approval shall be on 24 x 36-inch electronic sheets. o Benchmark and monumentation to City of Puyallup datum (NAVD 88) will be required as a part of this project/plat. o The scale for design plans shall be indicated directly below the north arrow and shall be only 1” =20’ or 1” =30’. The north arrow shall point up or to the right on the plans. o Engineering plan sheets shall be numbered sequentially in this manner: Sheet 1 of 20, Sheet 2 of 20, etc. ending in Sheet 20 of 20. o All applicable City Standard Notes and Standard Details shall be included on the construction plans for this project. A copy of the City Standards can be found on the City’s web site under Office of the City Engineer, Engineering Services.

STORMWATER • The addition of the hard surfaces shall be looked at as a common plan of development. Provide information that the new hard surface areas will be treated, and the existing modular wetland system has capacity for Minimum Requirement #6. Additionally provide an updated continuous modeling calculation showing that the flow control standard remains met. Provide a basin map within the storm report showing the threshold discharge area(s). The proposed design shall occur pursuant to the 2019 Stormwater Management Manual for Western Washington and current City Standards. [PMC 21.10] • Preliminary feasibility/infeasibility testing for infiltration facilities shall be in accordance with the site analysis requirements of the Ecology Manual, Volume III, Chapter 3.2, specifically: - Groundwater evaluation, either instantaneous (MR1-5) or continuous monitoring well (MR1-9) during the wet weather months (December 1 through April 1). - Hydraulic conductivity testing: o If the development triggers Minimum Requirement #7 (flow control), if the site soils are consolidated, or is encumbered by a critical area a Small-Scale Pilot Infiltration Tests (PIT) during the wet weather months (December 1 through April 1) is required for properties under 1 acre. Properties that are over 1 acre that have predicted low infiltration rates should perform Large Scale PIT Tests for better accuracy. o If the development does not trigger Minimum Requirement #7, 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 V Section 5.2.7.
