CITY OF PUYALLUP PERMITTING PORTAL

Other/Miscellaneous

GENERAL CIVIL - Civil engineering drawings will be required for this project prior to issuance of the first building permit (The city has transitioned to electronic review. Please reach out to the city permit technicians at PermitCenter@PuyallupWA.gov and they will guide you 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.

FRONTAGE IMPROVEMENTS FOR RESIDENTIAL INFILL LOTS - For the purposes of this policy, “infill” lots are individual parcels which were legally created and comprised of a singular single-family residence, duplex, or triplex project. Any person or entity who constructs or causes to be constructed any structure improvements which meet the level of substantial improvement as defined in PMC 11.08.120 on property fronting any dedicated street or other publicly owned street or alleyway shall construct curb, gutter, planter strips, street trees, sidewalks, storm drainage, street lighting, and one-half street paving (only required if the existing pavement condition is poor) in accordance with the city’s Public Works Engineering and Construction Standards and Specifications. The frontage improvements shall be required along all street frontage and alleys adjoining the property and any reasonable access to the property. Frontage improvements shall also be required where any reasonable access to the property connects to the public right-of-way, although the primary access is located on another parcel. The scope of the required frontage improvements may be scaled by the city to be proportional to the in-fill lot development.

This may result in the number of lots being reduced, or a reduction in other site amenities. [PMC 21.10.060(4), 21.10.150] • A Construction Stormwater General Permit shall be obtained from the Department of Ecology if any land disturbing activities such as clearing, grading, excavating and/or demolition will disturb one or more acres of land, or are part of larger common plan of development or sale that will ultimately disturb one or more acres of land. The application must be made 60 days prior to the discharge of any stormwater from the site. The link below may be used to obtain information to apply for this permit: http://www.ecy.wa.gov/programs/wq/stormwater/construction/ • The City will require an analysis from a wetland biologist and/or hydrogeologist to address Minimum Requirement #8 in accordance with Ecology manual Appendix I-D. This analysis will review your proposed discharge rate/duration/quality to the wetland and determine if there are any potential changes to the hydroperiod or impacts to the wetland ecosystem. The analysis will have to include a review of your offsite analysis and WWHM model as part of their determination. The stormwater report will need to be altered to include the analysis and any of the wetland Biologists/hydrogeologists recommendations to address any potential impact. This analysis will also have to be reviewed by planning to ensure that the analysis addresses their critical area code requirements. Also see Critical Areas notes from Planning. • All private storm drainage facilities shall be covered by a Stormwater Management & BMP Facilities Agreement provided by the City and recorded with Pierce County. Under this agreement if the owner fails to properly maintain the facilities, the City, after giving the owner proper notice, may perform necessary maintenance at the owner’s expense.
