Site Development Permit
Easements

Clean Water Services must hold easements for all public sanitary sewer, storm sewer, water quality/quantity facilities and vegetated corridors. For new development, most easements will be documented on the plats. Plat review is part of the Site Development process. Before construction starts, any off-site or unplatted easements must be approved and accepted by the CWS. Please refer to Standard language for platted easements for additional information.

Easement Vacation (Quit Claim)

In order for CWS to give up legal interest in an easement, the applicant must submit the required information and fee. If a facility in an easement is being relocated, the easement cannot be vacated until the relocation is complete and accepted by CWS.

Encroachment Approval

Only with CWS staff approval may a permanent structure be placed on or above a sanitary sewer or storm and surface water management easement. An approved encroachment must not limit CWS access to the facility for maintenance and repair. Approval is required for buildings and elevated structures such as decks and overhangs. To apply, submit information about the size and reason for the requested encroachment with the fee.
