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 2019 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 DOE manual. CIVIL PERMIT APPLICATION • 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 $470.00 (plus an additional per hour rate of $180.00 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: o Engineering plans submitted for review and approval shall be on 24 x 36-inch sheets. o Benchmark and monumentation to City of Puyallup datum (NAVD 88) will be required as a part of this project / plat. o The scale for design plans shall be indicated directly below the north arrow and shall be only 1”=20’ or 1”=30’. The north arrow shall point up or to the right on the plans. o Engineering plan sheets shall be numbered sequentially in this manner: Sheet 1 of 20, Sheet 2 of 20, etc. ending in Sheet 20 of 20. o All applicable City Standard Notes and Standard Details shall be included on the construction plans for this project. A copy of the City Standards can be found on the City’s web site under Office of the City Engineer, Engineering Services. Frontage Code: 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. Fee in Lieu -> Frontage Improvements a. The applicant may request and submit justification to pay a fee rather than constructing all or part of the required frontage improvements. Allowance of fee-in-lieu shall be at the discretion of the city and may be denied if the city engineer determines it will be more beneficial to the public to have the frontage improvements built along the street frontage adjoining the property or access to the property. The city will consider the following: o (i) The feasibility of accurately constructing improvements both horizontally and vertically to effectively drain runoff; o (ii) Whether constructed improvements can transition and connect smoothly with existing adjacent sites; and o (iii) Whether other frontage improvements will likely connect into the applicant’s required improvements within a reasonable time frame. b. The justification to allow use of the fee-in-lieu program shall not be based on cost savings to applicant in comparison with constructing required improvement adjacent to the property. The program will be administered with the following conditions: a. (i) Fees collected will be used towards pedestrian safety improvements, which could include lighting in the vicinity, ideally within one-half mile but up to one mile, from the contributing parcel in order to ensure that the improvements maintain a sufficient nexus to the project. b. (ii) Fees for residential infill lots and commercial tenant improvements shall be based on linear frontage of developing parcel. The fees will be posted on the city’s web page, “Fee-In-Lieu Program” and are initially set at $200.00 per linear foot of frontage where no concrete curb exists and $100.00 per linear foot with existing curb. The fees will be adjusted annually according to construction cost indices. If use of the fee-in-lieu program is for only a portion of the required frontage improvements, the fee will be established at an adjusted rate by the city engineer. If used for required frontage improvements from land subdivisions (formal plats, short plats, or binding site plans) and new commercial/industrial developments the fee will be developed based on the costs of installing the required improvements along the frontage of the development. c. (iii) The fees shall be capped at 15 percent of remodel or project valuation. d. (iv) Dedication of necessary right-of-way shall not be deferred or satisfied through payment of a fee-in-lieu. e. (v) The city shall track the collection of fees and the location of improvements funded by fees collected.

Zone XX and Use Allowance

The site is in the RM-10 zone district and the MDR Comprehensive Plan designated area. Consult PMC 20.25 for zone specific standards. In the RM-10 zone district, proposal for a duplex is a permitted use. However, the minimum density required for this lot is 3 dwelling units. Therefore, a duplex would not be permitted on this site, a triplex would have to be constructed, with all three units attached in one building. ADUs are not permitted at all in the City's RM zones. The City is currently considering changes to this regulation, if adopted, these changes would take effect in June 2025.

RM Zones Min Unit Density

Minimum Required Density: PMC 20.25.023: The minimum number of dwelling units per acre shall be established as follows for each RM zone, Where the calculation of allowable density results in a fraction 0.50 or above, the allowed dwelling unit count shall be rounded up. For density calculations resulting in 0.49 or less, the allowed dwelling unit count shall be rounded down:(1) RM-10: eight units per acre; In the event that the applicant can clearly demonstrate that due to environmental and/or physical constraints on the subject parcel that the minimum density cannot be achieved, the minimum density requirement shall not be applied. Subject property is 0.32 acres X 8 Units/acre = 2.56 = Minimum of 3 dwelling units must be constructed at this site.

RM Zones Max Unit Density

Maximum Allowed Density: PMC 20.25.022 The following formulas shall be used to calculate the maximum number of dwelling units permissible for each RM zone. Where the calculation of allowable density results in a fraction 0.50 or above, the allowed dwelling unit count shall be rounded up. For density calculations resulting in 0.49 or less, the allowed dwelling unit count shall be rounded down:(1) RM-10. The base density shall be 10 dwelling units per acre without utilization of density bonus allowed through PMC 20.25.0235. With utilization of density bonus, the maximum density shall be 14 units per acre. Acre calculations shall not include critical areas or buffers. Limited Density Transfer from Critical Area Buffers: The city shall allow transfer of density for residential uses from critical area buffers ONLY (not the critical area itself) to noncritical area portions of the same site; provided, that the resultant density calculated on the noncritical area land does not exceed 125 percent of the maximum developable density from that land otherwise allowed under zoning. No resultant lot area, width or depth shall be less than 25 percent that which otherwise would be required in the zone district. Subject property is 0.32 acres X 10 Units/acre = 3.2 = Maximum of 3 dwelling units must be constructed at this site.

Volcanic General Req.

Critical Areas: Volcanic Hazard Area: The site is within a volcanic hazard area. In the event of an eruption of Mt. Rainier, the site is expected to be inundated by pyroclastic flows, lava flows, debris avalanche, inundation by debris flows, lahars, mudflows, or related flooding resulting from volcanic activities. Uses and activities on this site shall comply with the city’s critical area ordinance (Puyallup Municipal Code 21.06, Article XII, section 21.06.1260, or succeeding section, regarding volcanic hazard areas. A triplex or duplex will not require any specialized reports in the volcanic hazard area.

Aquifer Recharge General Report Req.

Critical Areas: Critical Aquifer Recharge Area: The proposal is located within a Critical aquifer recharge areas. While this site is within this critical area, a duplex or triplex is unlikely to trigger aquifer recharge report requirements. Reporting requirements vary based on the proposed use of the property. Most land subdivisions for example, will not trigger these report requirements for the purposes of subdividing the land, but may be triggered by future planned use of the land. Activities that do not cause degradation of ground water quality and will not adversely affect the recharging of the aquifer may be permitted in a critical aquifer recharge area and do not require preparation of a critical area report; provided, that they comply with the city storm water management regulations and other applicable local, state and federal regulations. These activities typically include commercial and industrial development that does not include storage, processing, or handling of any hazardous substance, or other development that does not substantially divert, alter, or reduce the flow of surface or ground waters. Activities that have the potential to cause degradation of ground water quality or adversely affect the recharging of an aquifer may be permitted in critical aquifer recharge areas pursuant to an approved critical area report in accordance with PMC 21.06.530 and 21.06.1150. These activities include: Activities that substantially divert, alter, or reduce the flow of surface or ground waters, or otherwise adversely affect aquifer recharge; The use, processing, storage or handling of hazardous substances, other than household chemicals used according to the directions specified on the packaging for domestic applications; The use of injection wells, including on-site septic systems, except those domestic septic systems releasing less than 14,500 gallons of effluent per day and that are limited to a maximum density of one system per one acre; Infiltration of storm water from pollution-generating surfaces; or Any other activity determined by the director likely to have an adverse impact on ground water quality or on a recharge of the aquifer.
