STORMWATER MANAGEMENT APPLICATION
Purpose
All new development and redevelopment must conform to the standards and minimum requirements set by the
Washington Department of Ecology Stormwater Management Manual for the Puget Sound Basin (SMM)currentlyadoptedbyJeffersonCountyandbeaccompaniedbyastormwatermanagementpermitifrequiredbyJCC18.30.070(5).
You will submit a Master Land Use Application Form in conjunction with this supplemental application.The
Administrator may require additional measures as indicated by the environmental review or other site plan review.For
projects that involve a building or land use permit,stormwater review will occur as part of your overall application
review.A stand alone stormwater management permit is requiredfor clearing and grading activities exceeding 7,000sq/ft that do not involve a building permit or other land use approval (ie.preparing land for future construction,clearing for speculative purposes,etc.).
A stormwater management permit is required for the following activities:
e All grading of 500 cubic yards or more;except for those activities exempted under JCC 18.30.070(5)
e All clearing and grading activities within environmentally sensitive areas as defined within 18.22 of
the JCC;
e Land-disturbing activities of 7,000 square feet or more;or
e Creation of 2,000 square feet or more of impervious surface
Exempt Grading Activities
The following activities are exempt from the requirements for a stormwater management permit (if located outside of
an environmentally sensitive area)under the provisions of 18.30.070 of the JCC:
Maintenance of gravel roads;
A SEPA-exempt residential driveway;
Construction of a Class I-Ill logging road (per RCW 76.09.050 and WAC 222);
Construction of drainage improvements in accordance with the JCC;or
Construction of a pond of one-half acre or less which is not in a regulated wetland.
Stormwater Disposal Policy Along Marine Shorelines
Pursuant to JCC 18.22.130(2)all new development activity,including single-family residential construction,located onMarrowstoneIsland,Indian Island and within 500 feet of any marine shoreline is required to infiltrate stormwaterrunoffonsite,to the maximum extent practicable.This provision is intended to prevent seawater from intruding intoundergroundaquifers,reduce non-point source pollution to marine waters,and reduce the potential for shoreline
erosion due to tightline failure.This provision is interpreted as establishing a hierarchy in which the first and best
alternative is on-site infiltration using drywells or other methods,the second best alternative is upland off-site disposal,
and the least preferred alternative is direct discharge into marine waters through a stormwater tightline.In order toutilizetheleastpreferredalternative,a stormwater tightline discharging directly into marine waters,applicants mustdemonstratethroughageotechnicalorsimilarreportpreparedbyalicensedprofessionalthatbothon-site infiltrationanduplandoff-site disposal are not practicable or feasible.The report must include cost figures for comparison.

Exhibit 09
Please note that if a stormwater runoff tightline that terminates at or near the marine shoreline is allowed to be
included in a development application,review under the Jefferson County Shoreline Master Program,the State
Environmental Policy Act (SEPA)and other agency approvals (such as Hydraulic Project Approval from the Department of
Fish and Wildlife)may be required as well.A Joint Aquatic Resources Permit Application (JARPA)form would need to
accompany any permit application which includes a stormwater tightline at or below the ordinary high water mark.
Criteria
Prior to issuance of a stormwater management permit,the applicant shall submit a Master Land Use Application (MLA)
and the required stormwater management plans to the Administrator for review and approval.The development
definitions,criteria and thresholds for determining stormwater management plan requirements from the adopted
Stormwater Management Manual (SMM)are found in 18.30.070 of the JCC.This includes minimum requirements and
thresholds for developing a:
e Small Parcel Erosion and Sediment Control Plan;
e Large Parcel Erosion and Sediment Control Plan;
e Permanent Stormwater Quality Control Plan (PSQC)
Process
The Administrator of the Department of Community Development will issue the stormwater management permit
consistent with a Type
|
(administrative)permit process only upon a finding that the proposed use or activity meets all
applicable requirements of 18.30.060 and 18.30.070,and any other applicable requirements of the JCC.
