RE: ENTRANCE EMBELLISHMENTS (____________ TENTATIVE)
DEAR MR. TURNER:
AS DEVELOPER OF THE PROPOSED __________________ SUBDIVISION,
I AM AWARE THAT THE FOLLOWING NOTE IS NOW REQUIRED NOT ONLY
ON TENTATIVES BUT ALSO ON RECORD PLATS.
"NO STRUCTURE EMBELLISHMENTS WILL BE ALLOWED ON VDOT
RIGHT-OF-WAY WITHOUT THE COMMITMENT OF, OR THE ISSUANCE OF,
A VDOT LAND USE PERMIT. WITHIN THE 10' CLEAR ZONE (MEASURED
FROM THE EDGE OF THE ROADWAY'S PAVEMENT OUT
10'), NO STRUCTURE EMBELLISHMENT WILL BE PERMITTED THAT IS
CLOSER THAN 3' FROM THE EDGE OF PAVEMENT OF THE PUBLIC
STREET OR HIGHER THAN 6" ABOVE THE SURFACE OF THE DRIVE."
I WILL DO ALL POSSIBLE TO PROVIDE THE CORRECT INFORMATION
FOR BUILDERS OR CITIZENS CONSTRUCTING ENTRANCE
EMBELLISHMENTS.
I AM ALSO AWARE THAT, PRIOR TO STATE ACCEPTANCE OF THE
ROADS, I AM RESPONSIBLE FOR REMOVING EMBELLISHMENTS THAT DO
NOT MEET STATE STANDARDS.
