(1) Drainage easements shall be required where stormwater conveyance, storage, or treatment facilities identified in development plans are not located in public rights-of-way, and where access to stormwater facilities is required. Drainage easements shall be granted to the persons responsible for providing ongoing maintenance of the drainage systems. Drainage easements through structures are not allowed. Easements shall be of a width and location sufficient to allow access for equipment that would normally perform maintenance activities.

(2) Stormwater and conveyance facilities that are to be maintained by Clallam County, together with maintenance access roads to the facilities, shall be located in public right-of-way, in separate tracts dedicated to Clallam County, or corresponding to drainage easements granted to Clallam County.

(3) The approved drainage permit under this chapter will be available on the Clallam County On-Line Permit System. This shall include the identification of flow controls (i.e., drywells, dispersion trenches, rain gardens, etc.) and low impact development BMPs (full dispersion through natural vegetation) on the approved drainage permit site plan, along with the landowner’s responsibility for operation and maintenance of these permanent stormwater BMPs. Any modifications of the approved drainage permit will require prior approval by the County Engineer, or their designee.

(4) Any flow control and runoff treatment BMPs for which the applicant identifies the operation and maintenance to be the responsibility of a private party must have a declaration of covenant and grant of easement which shall be recorded on the title of the parcel.
