GENERAL • The comments provided below are intended to assist the project proponent with incorporating City requirements into the project documents, but should not be considered an exhaustive list of all necessary provisions from the PMC, design standards, or the Ecology stormwater manual. • The proposed development site is currently an active cleanup site for contaminated soils. The City has been working diligently with the Dept. of Ecology (Ecology) to ensure the site is remediated. Groundwater monitoring is ongoing and the City is optimistic that the cleanup efforts (excavation and bioremediation) taken to date are working in accordance with the approved cleanup plan. The City has approached the Dept. of Ecology requesting the site be evaluated for a “No Further Action Determination”, but the City has not received a response as of this writing. Once Ecology responds, it will take four consecutive quarters of clean test results before the final NFA can be issued. The project proponent should be aware that there may be design and construction constraints imposed by Ecology as part of any development. • The City is in the early stages of determining the Festival Street design criteria. An SOQ will be released in early 2023 to select a consultant to assist the City and it is anticipated the final design criteria will be completed in early 2024. • 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]. • Comments regarding design and construction of new utilities and road improvements are provided for the developer’s information and use. Unless specifically noted, construction of these infrastructure improvements is not a condition of landuse approval. However, infrastructure improvements must be approved and permitted prior to issuance of the first building permit associated with the project. [RCW 58.17.120 and 19.07.080] • More coordination with the city will be required if the townhouses remain and a major plat is required.

[PMC 14.08.070] • Any proposed connection to the City sewer system shall be designed and constructed to current City standards. [PMC 14.08.070] • Refer to City Standards, Section 400 for Sewer System Requirements. [PMC 17.42] • There is an existing 8-inch dead-end sewer main located in E Main approximately 120-ft east of 2nd St SE and roughly 4-ft deep. There is a 6” line that was installed 100’ further east of the cleanout shown in public GIS. The city will require any sewer main tap to come from an 8” main, which may require a main extension to provide new connections. In addition, there is an existing 8-inch dead-end sewer main on E Meeker approximately 50-ft east of 2nd St SE and approximately 4-ft deep. There is a 6” line that was installed 165’ east of this. This sewer line ends at a structure that will need to be upgraded to a city standard manhole. • For this comment, go to the CityView Portal and download the document named “COP Sewer Exhibit”. The sanitary mains and structures (shown in red) are not mapped in GIS. It is assumed that no active connections are existing on these portions, although lateral connections were seen on the city’s camera footage. With development of the Cornforth-Campbell parking lot, new sanitary lateral connections would not be allowed on these portions based on being undersized, non-standard materials and quality deficient. Any extensions to the sanitary mains would require removing the mainline cleanouts (shown in GIS as the starting points) and installing new manholes at their new beginning extents. If no extension would be required, although doubtful, the existing mainline cleanouts would need to be replaced with manholes at their current locations and the unmapped portions of main and structures be removed or decommissioned per WSDOT standards. • As of this writing, there are no known sewer constrictions in this system within ¼-mile of the proposed project. • Sanitary sewer mains shall be 8-inch minimum and located 5-feet east or north of roadway centerlines.
