GENERAL: • This pre-application is associated with a previously approved, but expired, project. Based on the site plan provided, the proposed project appears to be the same scope-of-work as the expired project. Therefore, the comments provided below are intended to reinforce our mutual understanding of the previously approved project and the upcoming proposed project. • 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].

APPLICANT SPECIFIC ‘ENGINEERING’ RELATED QUESTIONS: • QUESTION-Civil Engineering application and review (E-21-0286) was last submitted in May 2022 which was approved. Understanding this permit is now expired, we are seeking the renewal of these permits or if or if new plans and reports will be required. RESPONSE: New civil plans and supporting documentation will have to be provided for review and approval to ensure current standards and regulations are reflected on the permit documents. For example, the storm report shall be revised to reflect the currently adopted stormwater manual (2019 Ecology Manual), and current standards require trash enclosures to be connected to sewer. • QUESTION-Frontage improvement and right-of-way requirements; -Will the City be continuing with their CIP of N Avenue SE? If so, what is the expected timing of construction? -Will the City be providing frontage improvements for this project (curb, gutter, sidewalk, planter and driveway approach)? RESPONSE: The City anticipates going to bid on the 7th Ave SE Sidewalk Project in the summer of 2024. Frontage improvements will be constructed by the City as part of the CIP project. The applicant shall coordinate their project improvements with the City’s CIP project to ensure both are compatible. • QUESTION-Storm water location and the associated connection fees (if any); RESPONSE: The projects stormwater design shall be coordinated with the City’s upcoming CIP sidewalk project. Based on the previously approved civil drawings, the projects proposed stormwater discharge location was in direct conflict with the City’s existing watermain in 7th Ave SE. If the discharge location remains unchanged, the applicant will be required to relocate the watermain at their expense. As mentioned in the Stormwater Section above, current Stormwater SDCs are $4,085.23 per ESU. • QUESTION- Water requirements and connection fees RESPONSE: See Water section above. • QUESTION- Sewer requirements and connection fees RESPONSE: See Sewer section above.
