Permitting Process (New Development)

If the proposed project has stormwater features requiring a SWMA, the Certificate of Occupancy will not be issued until the agreement is completed, signed, and recorded at the SLCO Recorder's office along with a Stormwater Management Plan. 

Discussion of the requirements will be addressed during the Grading Review phase by the Grading Reviewer.
