Hello Keystone Homes, Inc.,

Thank you for submitting your project to City of Winston-Salem. Review of the plans for this project have been
completed. The design is adequate to meet the ordinance standards and the plans have been approved.
If you have not already done so, please provide an original signed and notarized Financial Responsibility/Ownership
(FRO) form as applicable. This document is required prior to the issuance of the Grading/Erosion Control Permit. If this
has already been provided, then please disregard this statement. Reminder that a completed FRO form is not required in
the instance where a project qualifies to use the BB 489 Sketch Erosion Control Plan document.
If this project will disturb more than 1 acre or is part of a larger common plan of development, the Grading/Erosion
Control Permit cannot be issued until documentation is provided that coverage under the NCGO1 Construction
Stormwater Permit (NPDES) has been obtained. Please obtain coverage under the permit at the following website
(https:Hedocs.deci.nc.eov/Forms/NCGOI-NOI). Once coverage is obtained please upload a copy to the project
documents in the electronic plan review system. The Grading/Erosion Control Permit will not be issued until proof of
coverage under NCGO1 is provided.
As outlined in the Unified Development Ordinances (UDO) of Winston-Salem/Forsyth County, Village of Clemmons,
Town of Lewisville, and Town of Walkertown, Erosion Control Division staff may periodically inspect sites of land
disturbing activity to determine compliance with the Erosion Control ordinances and the approved Erosion Control
Plan. No person shall willfully resist, delay, or obstruct an authorized representative, employee, or agent of the Erosion
Control Division while that person is inspecting or attempting to inspect a land disturbing activity under the ordinance.
Should you have any questions as you move forward please feel free to contact Matthew Osborne at 336-462-7480 or
matthewo(a.citvofws.ora.
Let me know if you need anything additional from Erosion Control staff at this time.
