Traffic scoping worksheet will be required. 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.
Park Impact Fee (Per residential dwelling Unit):
Less than 500 sqft $1,560.05
500 - 999 sqft $2,313.53
1,000 – 1,999 sqft $3,291.31
2,000 sqft or more $4,017.30
ADUs are charged 80% less for Traffic Impact Fees & Park Impact Fees.
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.
o 9th St SW – old curb cuts need to be replaced – City inspector would need to go out and evaluate the existing condition of pavement & frontage. Any sidewalk panels or curb/gutter that are in poor condition would need to be replaced
o 10th St SW would need to be constructed to current City standards include new curb/gutter/sidewalk and planter strip. The existing utility pole located on the corner would need to be relocated
The City Engineer would be open to accepting fee-in-leu as an alternative to constructing frontage. As a condition, the City would still require the roadway width to be widened to 20ft with the fee-in-leu option.

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 below 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.
CIVIL PERMIT APPLICATION
A civil permit application is required for any project required to construct frontage at a site that doesn’t have existing vertical curb, and a project proposing new connections to city.
• 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. 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 per hour rate of $130.00 in excess of 5 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 Estimate form. [City of Puyallup Resolution No. 2098]
• Civil Engineering drawings shall conform to the following City standards Sections 1.0 and 2.0:

UTILITIES:
The utilities requirements in the notes below applies to the scenario the project becomes a Duplex with an ADU.
WATER
Water Within City Service Area:
• There is a 6” Cast Iron Public water main on the opposite side of 9th St SW and a 6” Ductile Iron public water main ending approximately 90 feet west of the subject parcel on the parcel side of 10th Ave SW.
• A water meter box serving this parcel exists at the time the GIS imagery was taken in the frontage of 9th ST SW. This is not verification of the presence of an existing meter.
• Any proposed water system shall be designed and constructed to current City standards. [PMC 14.02.120]
Water Meter Options
Option 1
Provide 2 meters to provide water to the Owner Unit/ADU and the tenant unit. This method charges each owner individually for water consumption.
Option 2
Provide a single water meter and split water costs among tenants.
• Any wells on the site must be decommissioned in accordance with Washington State requirements. Documentation of the decommissioning must be provided along with submittal of engineering drawings. If an existing well is to remain, the well protection zone shall be clearly delineated and appropriate backflow protection (Reduced Pressure Backflow Assemblies) shall be installed at all points of connection to the public water system. [PMC 14.02.220(3)(b)]
• The City will provide and install the water meters required to service the site. Note: a 1” minimum water meter is required for buildings requiring a sprinkler system [PMC 14.02.120(f) & CS 301.3]
• To demo a private well: The applicant is responsible to demolish the existing private well per Tacoma Pierce County Health Department requirements. A decommissioning certificate shall be filed with Pierce County and a copy submitted to the City of Puyallup.
• Any existing services that are to be abandoned at this site shall be disconnected at the main, the corp. stop removed, and the service plugged to city standards. [PMC 14.02.120(f)]
Backflow Protection:
• If a Fire Sprinkler system is required, a reduced pressure backflow assembly (RPBA) will be required on the domestic line at each location where the proposed water main connects to the public system. [PMC 14.02.220(3) & CS 302]
• 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. 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
• There appears to be a sewer cleanout on the property connected to an 8” concrete sewer Main in 9th St SW.

• Side sewers shall have a cleanout at the property line, at the building, and every 100 feet between the two points. [PMC 14.08.120 & CS 401(6)]
• The applicant may need to provide a new connection into the existing public system located within 9th St SW.
• The City Sewer Department must conduct a visual inspection of a previously used side sewer to determine if that side sewer can be used again. Existing laterals must meet current standards to be used again. It is the responsibility of the property owner to expose the line as necessary for that inspection. The City reserves the right to request video inspection of the side sewer to assist in its determination. Redevelopment projects shall utilize the existing trench where possible. CS 401(15) and CS 401(16)
