•Traffic scoping worksheet will be required for this project. The City policy requires the project trips to be estimated using the Institute of Transportation Engineers’ (ITE) Trip Generation, 11th Edition. In general, trip generation regression equations shall be used when the R2 value is 0.70 or greater. For single-family units and offices smaller than 30,000 SF, use ITE’s Trip Generation, average rate. The project trips shall be rounded to the nearest tenth. Trip credits would be allowed for any existing development. The city has adopted a City-Wide Traffic Impact Fee of $4,500 per PM peak hour trip. Final fees will be calculated and assessed by the City at the time of building permit issuance. 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. -Frontage improvements will be required along Todd Rd. Frontage improvements shall match improvements constructed for the adjacent property (to the west). 8ft sidewalks + 17ft roadway width (from centerline) -As part of these improvements, additional right-of-way (ROW) may need to be dedicated to the City. -Approximately 10.5ft of ROW dedication will be required -Offsite paved taper will be required east of frontage Commercial Driveway will be required – minimum 30ft width This commercial development shall provide an autoturn analysis for the largest anticipated vehicle that would access the site. Curb radii and entrance dimensions shall be increased as necessary to allow vehicles to access the site without encroaching into adjacent lanes of traffic. -Want to ensure vehicles will not be backing into the property. At the time of civil permit review provide a separate pavement striping plan (channelization) sheet for the city to review. On-site monument signage must be located outside sight distance triangle.

Engineered plans must follow the latest regulations and standards set forth in the Puyallup Municipal Code (PMC), the City Standards for Public Works Engineering and Construction (design standards), and the current City adopted stormwater manual at the time of civil permit application [PMC 21.10.040]. The stormwater design associated with this Development Permit will be reviewed for compliance with the 2014 amended Stormwater Management Manual for Western Washington (ECY manual), which is the current adopted stormwater manual. The comments provided are project-specific in nature and should not be considered an exhaustive list of the requirements from the PMC, design standards, or the ECY manual.

[PMC 21.10.040] • Preliminary feasibility/infeasibility testing for infiltration facilities 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 well (MR1-9) during the wet weather months (December 21 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 21 through April 1) is required. 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 III Section 3.3.8. • If infiltration facilities/BMPs are feasible, the number of tests shall be based on the area contributing to the proposed facility/BMP, e.g., one test for every 5,000 square feet of permeable pavement or one test for each bio-retention cell. • Erosion control measures for this site will be critical. A comprehensive erosion control plan will be required as part of the civil permit application. • The applicant shall include a completed stormwater flowchart, Figure 3.1, contained in Ecology’s Phase II Municipal Stormwater Permit, Appendix I with the stormwater site plan. The link below may be used to obtain the flowchart: • Public right-of-way runoff shall be detained and treated independently from proposed private stormwater facilities. This shall be accomplished by providing separate publicly maintained storm facilities within a tract or dedicated right-of-way; enlarging the private facilities to account for bypass runoff; or other methods as approved by the City Engineer. [PMC 21.10.190(3)] Stormwater Retention/Detention (R/D) Facilities: • Overflow facilities shall be provided for any proposed R/D facilities in accordance with City standards.
