The Encroachment Permit establishes a uniform standard for encroachment upon roads in the State Highway System so as to provide for the safe and efficient movement of traffic while allowing reasonable access to abutting property. The Application for Encroachment Permit is a request to SCDOT for permission to perform work on SCDOT maintained rights-of-way. An approved permit grants the Applicant permission to encroach on the roadway within the guidelines established on the permit.
The South Carolina Department of Transportation provides several methods for obtaining an encroachment permit.
Permit Form: The completed form is required.
Drawing: Give details of the proposed work and existing conditions and including, but not limited to, the following:
Note: If submitting a hardcopy application, drawing should be submitted on 8 1/2in x 11in [or 11in x 17in] size paper. A 36in x 22in site plan showing the relationship of the driveways to the circulation plan and the site development may be required. It is recommended that a 36in x 22in site plan be submitted initially to facilitate review of the application.
All Drawings Must Be To Scale!
Proof of Bonding: Evidence of any required bond must accompany the permit application.
Storm Water Management and Sediment Control Plan: All applications for encroachment permits that involve bringing storm water runoff or sediment to the highway for a developed area of 2 acres or more must include a copy of a Storm Water Management and Sediment Control Plan approved by DHEC, the local government, or the conservation district responsible for approving such plans pursuant to The Storm Water Management and Sediment Reduction Act. See S. C. Code Ann. Section 4814-10, et seq. (Supp. 1995). The plan should include drainage design computations. If the area is less than 2 acres, the application must include a drainage plan with supporting design computations limiting the post construction 10-year peak discharge to the pre-developed 10-year peak.
Bridges, Culverts, Retaining Walls or other Significant Structures: All applications for encroachment permits that involve these types of structures must include a signed and sealed copy of the Geotechnical Report, Hydrology Report, Construction Plans and Documents, and Structural Design Calculations as outlined in Chapter 12 of the Access and Roadside Management Standards Access and Roadside Management Standards (ARMS).
