This form is required for all residential building projects along with specific site and project data.
Site Plan
Draw site plan to scale, not less than 1-inch=100-feet, show all property corners, existing and proposed structures, adjacent roads, all storage tank locations, all easements, utility locations, and north arrow. The site plan may incorporate the erosion, pollution, and stormwater control requirements of a site development permit. This combined plan is sometimes referred to as an abbreviated plan or stormwater site plan.
Building Construction Drawings
Draw plans to scale, the preferred scale is ¼-inch = 1-foot, and include dimensions. A complete set of drawings includes a foundation plan, framing plans, floor plans, cross sections, and elevations.
Structural Engineer Calculations
Engineering calculations are required whenever a structure doesn't meet conventional light frame construction standards. Submit structural design drawings separately from architectural drawings. Both calculations and drawings must be stamped by a licensed professional engineer.
A Driveway Approach Permit is required for: a new driveway approach that connects to a public road, an existing driveway approach that was never permitted or built to County standards, and to modify or rebuild an existing driveway approach. View 17B.10.101 Driveway Approach Required Permit.
Emergency Vehicle Access
Clearly identify emergency vehicle access on the site plan. Requirements: 15' wide when serving one home; 18' wide when serving more than one home. Pierce County Code Table 17C.60.150-1 calls out EVA width.
Energy efficiency and ventilation calculations may be required, based on the International Energy Conservation Code of Washington State (IECC-WA) and Washington State Energy Code (WSEC).
Sewer work on residential property; single-family, duplexes, and accessory dwelling units, requires review by the County Public Works Department sewer division.
Site Development Permit
Most new single-family and new duplex construction will require a site development permit to ensure that erosion, pollution, and stormwater runoff is controlled during and after construction.
