GENERAL • 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 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. • Show on plans for Civil submittal lay down areas for new building materials and stockpile areas for excavated materials.

WATER Water Within City Service Area: • The proposed water system shall be designed and constructed to current City standards. [PMC 14.02.120] • The minimum distance between water lines and sewer lines shall be 10-feet horizontally and 18-inches vertically. If this criterion cannot be met, the design shall isolate the sewer and water lines by encasement, shielding or other approved methods. • A 2-inch blow-off assembly is required on dead-end water mains except where fire hydrants are installed at the dead-end. [PMC 14.02.120(f) & CS 301.1(7)] • Water pipe and service connections shall be a minimum of 10-feet away from building foundations and/or roof lines. • The applicant is required to provide backflow protection on the domestic line(s) in accordance with City Standards. The minimum level of protection would be a double check valve assembly (DCVA). However, the city requires a reduced pressure backflow assembly (RPBA) for any use considered to be a high hazard as outlined in WAC 246-290-490 Table 9. PMC 14.02.220(3) & CS 302.2] • If an RPBA is not appropriate then the applicant shall provide backflow protection with the installation of a double check valve assembly (DCVA) on the domestic connection to the public water main, if one does not currently exist. A plumbing permit is required for this work to be completed; and the unit should be located outside the building, immediately downstream of the existing water meter if possible. If an irrigation system is also proposed, a DCVA is required on that line as well. [PMC 14.02.220(3) & CS 302.2]

SEWER • The proposed sewer system shall be designed and constructed to current City standards. [PMC 14.08.070, 17.42 and CS 400] • Sewer main pipe and service connections shall be a minimum of 10-feet away from building foundations and/or roof lines.

Other/Miscellaneous

STORM • Design shall occur pursuant to the 2019 Stormwater Management Manual for Western Washington and current City Standards. [PMC 21.10] • The applicant is responsible for submitting a preliminary stormwater management site plan which meets the design requirements provided by PMC 21.10 and Ecology Manual Volume I, Section 3.4.1. The preliminary stormwater site plan (PSSP) shall be submitted prior to Preliminary Site Plan approval to ensure that adequate stormwater facilities are anticipated prior to development of the individual lot(s). The preliminary stormwater site plan shall reasonably estimate the quantity of roof and driveway stormwater runoff and the application of On-site Stormwater Management BMPs for the proposed development. • The applicant shall include a completed stormwater flowchart, Figure I-3.1 for New Development and Figure I-3.2 for Redevelopment in the Stormwater/Drainage Report. • 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. [PMC 21.10.190 and MR#5 from the Ecology Manual] • An erosion control plan will be required as part of the civil permit application. The following items may be required to be included at the time of Civil permit submittal: • A permanent storm water management plan which meets the design requirements provided by PMC Section 21.10. The plan and accompanying information shall provide sufficient information to evaluate the environmental characteristics of the affected areas, the potential impacts of the proposed development on surface water resources, and the effectiveness and acceptability of measures proposed for managing storm water runoff. The findings, existing and proposed impervious area, facility sizing, and overflow control shall be summarized in a written report. [PMC 21.10.190, 21.10.060] • The permanent storm water management plan shall clearly delineate any offsite basins tributary to the project site and include the following information: [PMC 21.10.060] o the quantity of the offsite runoff o the location(s) where the offsite runoff enters the project site o how the offsite runoff will be routed through the project site o the location of proposed retention/detention facilities o and the location of proposed treatment facilities • All pipe reaches shall be summarized in a Conveyance Table containing the following minimum information and included in the report: o Pipe Reach Name o Structure Tributary Area o Pipe Diameter (in) o Pipe Length (ft) o Pipe Slope (%) o Manning’s Coefficient (n) o HGL for each Pipe Reach o Design Flow (cfs) o Water Depth (in), Velocity (fps) and Percent Full (%) at Design Flow o Flow (cfs) and Velocity (fps) at Pipe-Full o Critical Depth (in)

GRADING • A Grading Plan conforming to all requirements of PMC Section 21.14.120 will be required prior to infrastructure construction. The Plan shall be prepared by a Civil Engineer licensed in the State of Washington. [PMC 21.14.070] • The following notes shall be added to the first sheet of the TESCP: “If at any time during construction it is determined by the City that mud and debris are being tracked onto public streets with insufficient cleanup, all work shall cease on the project until this condition is corrected. The contractor and/or the owner shall immediately take all steps necessary to prevent future tracking of mud and debris into the public ROW, which may include the installation of a wheel wash facility on-site.” “Contractor shall designate a Washington Department of Ecology Certified Erosion and Sediment Control Lead person and shall comply with the Stormwater Pollution Prevention Plan (SWPPP) prepared for this project.” “Sediment-laden runoff shall not be allowed to discharge beyond the construction limits.” “The permanent BMPs shall not be utilized for TESC runoff. Connect BMPs to road system only after construction is complete and site is stabilized and paved.” • A geotechnical report conforming to all requirements in PMC Sections 21.14.150 and 21.14.160 will be required prior to civil/grading/stormwater review. The Report shall be prepared by a Civil Engineer or Engineering Geologist licensed in the State of Washington.

Other/Miscellaneous

Per Puyallup Municipal Code Section 11.08.135, the applicant/owner would be expected to construct half-street improvements including curb, gutter, planter strip, sidewalk, roadway base, pavement, and street lighting. Any existing improvements which are damaged now or during construction, or which do not meet current City Standards, shall be replaced. If frontage improvements are triggered (exceeding $200K of improvements), the City would require a City standard commercial driveway (30ft wide commercial radius with 35ft radii ) 10ft ROW dedication would be required to meet our future 60ft ROW section.
