Surface water: No surface water bodies exist on the site, except the stormwater detention
pond, which does not contain permanent storage.
Shorelands and Wetlands: There are no wetlands on the property, and the property is not near
the shoreline or within the shoreline management act jurisdictional area.
Floods: The FEMA maps indicate no floodlands on the property.
Groundwater: No groundwater will be withdrawn for this project. The 42 acre property is
served by the Port Townsend water supply system.
Water Run-off (including stormwater): Review of stormwater management is provided by the
Jefferson County Department of Public Works (Memorandum of March 29, 2011). The proposal
will require approximately 35,000 s.f. of land disturbing activity, and will include excavation and
filling to construct a berm around three sides of the range. A covered shooters' shed and
parking spaces also will be constructed. The project will create approx. 2,500 s.f. of new
impervious surface. Existing site drainage and stormwater runoff from the access road and rifle
and pistol range is conveyed to an approx. 100 x 200 ft. impoundment on the northerly area of
the rifle range. Impounded water infiltrates and does not flow off of the site [see comments
regarding soil type]. Runoff from the project site will also be conveyed to this area.
The Jefferson County Unified Development code, Section 18.30.070 Stormwater Management
Standards adopts the standards and minimum requirements of the Washington Department of
Ecology Stormwater Management Manual for Western Washington. The proponent has
submitted a Jefferson County Stormwater Site Plan Template dated 7/26/2010 that analyzes
stormwater management issues related to the proposed development. The Template includes
the elements of a construction Stormwater Pollution Prevention Plan. The proponent shall
implement the best management practices from the template while constructing the pistol
range. The Public Works Department has issued standard conditions of approval based on
adopted standards for this project, which will be attached to the staff report and Notice of
Decision. No further environmental mitigation for stormwater management and erosion
control are required for this project beyond adopted standards. However, see comments on
Environmental Health related to lead management and water quality as it pertains to
stormwater management.
Plants: A critical area review of the site has been conducted and no special plant species have
been identified. The proposal is not likely to result in significant adverse impacts to plants. No
mitigation measures are proposed. Additional analysis of the proposal and its effects related to
PLANTS is not necessary.
Animals: An ESA check was conducted and no threatened or endangered species have been
identified on the parcel. The proposal is not likely to result in significant adverse impacts to
sensitive species of Animals. No mitigation measures are proposed. Additional analysis of the
