The Albemarle County Attorney approved the 120' access easement expressly for the
rezoning of TMP 90-35L. The attached deed (DB 5119 PG 321-327) permits
construction for private access from Avinity Dr for the benefit of TMP 90-35L. Since
this driveway falls under the conditions listed in the deed, we have full right to construct
this entrance as shown.
