DRIVEWAY CONSTRUCTION & MAILBOX SPECIFICATION Orange County has required that driveways be located at alternating lot corners, beginning with the Southern boundary of Lot #1. The benefit of this driveway location approach is a reduction in the number of break points along the roadway and improved roadside appearance. Significant design effort has been spent to develop a design specification that implements the Orange County requirements while ensuring that the final appearance of driveways will be aesthetically pleasing. Issues of timing, grade, shaping, planting, and mailbox location have been carefully considered to, hopefully, anticipate and overcome undesirable, unintended outcomes. As required by Orange County, during the first 45 feet of run, a driveway may not extend further than 20 feet laterally from the lot side-line. After 45 feet, a driveway may curve as appropriate for the given site. Drawings pertaining to the first 20x50 foot envelope are attached.

A.1 CONCEPTUAL SKETCH Early design sketch showing mailcar access (Mailbox locations are no longer contained in one structure due to maintenance, ownership, construction timing, and positioning issues and are to be separated as shown in other drawings) This sketch is for illustration purposes only. See the following drawings for construction and mailbox details. V12.0 2
A.2 DRIVEWAY CONSTRUCTION & DIMENSIONS Surface: Driveway shall be black asphalt (I2) for the first 50 feet from the roadway. Thereafter, asphalt, compacted crushed stone, clay brick, interlocking precast pavers, or pigmented concrete are acceptable. NO WHITE OR NEAR-WHITE CONCRETE. Culvert: Must be concrete (RCP), as specifically specified by NCDOT. First driveway installation (if future adjacent driveway not yet installed): 1) Pave turn-out (see drawings below) 2) Continue culvert underneath the center median section. Add dirt if necessary to allow for median planting and mailbox placement. 3) Set culvert at a grade that will permit the 2 nd driveway s drainage culvert pipe to connect and drain properly and allow for 8+ gravel/asphalt over the culvert. Left Driveway First: Mail Car Pull-off 8 Ft wide Right Driveway First: Second driveway installation: Connect to mail car pull-off as shown. V12.0 3

A.4 - CULVERT-END PLANTING AND/OR HEADWALLS PLEASE CHOOSE ONE OF THE FOLLOWING OPTIONS: OPTION 1) STONE HEADWALL: DISCLAIMER: FROM 2001 2010, THE NORTH CAROLINA DEPARTMENT OF TRANSPORTATION REVERSED THEIR POSITION ON THE ALLOWABILITY OF STONE HEADWALLS IN THE ROAD RIGHT-OF-WAY IN A NEIGHBORHOOD SUCH AS TUSCANY RIDGE FROM NOT ALLOWING THEM TO THE CURRENT GUIDANCE, AS OF OCTOBER, 2010, WHICH IS THAT HEADWALLS ARE ACCEPTABLE UNDER THE DESIGN SPECIFICATIONS BELOW. THE NCDOT RIGHT-OF-WAY EXTENDS 15 FEET FROM THE EDGE-OF-PAVEMENT. THIS RIGHT-OF-WAY IS AN AREA WHERE NCDOT IS AUTHORIZED TO UNDERTAKE ANY AND ALL ROAD REPAIR OR MAINTENANCE ACTIVITIES THEY CHOOSE TO UNDERTAKE. NCDOT HAS NOT PROVIDED A WRITTEN APPROVAL TO INSTALL SUCH HEADWALLS, AND IT IS NOT EXPECTED THAT THEY EVER WILL. OWNERS CHOOSING TO INSTALL HEADWALLS SHOULD BE AWARE THAT IN THE FUTURE, THERE IS A POSSIBILITY THAT NCDOT COULD REQUEST REMOVAL OR OTHER ADDRESSMENT OF HEADWALLS. AS OF OCTOBER, 2010, NCDOT HAS VERBALLY APPROVED INSTALLATION OF HEADWALLS. WHILE WE THINK THE PROBABLITY IS LOW, IT IS NOT POSSIBLE TO KNOW WHETHER NCDOT WILL CHANGE THEIR POSITION ON HEADWALLS IN THE FUTURE OR ATTEMPT TO REQUIRE ALTERATIONS TO EXISTING HEADWALLS. BASED ON THE ABOVE BACKGROUND INFORMATION, HOMEOWNERS WHO INSTALL HEADWALLS, BY VIRTUE OF INSTALLING THEM, THEREBY ASSUME FULL RESPONSIBILITY FOR ANY REMOVAL OR OTHER COSTS ASSOCIATED WITH THEIR HEADWALLS. PLEAES ALSO BE AWARE THAT HEADWALLS IN THE NCDOT RIGHT- OF-WAY COULD BE DAMAGED BY NCDOT ROADCLEARING OR REPAIR EQUIPMENT AND ALTHOUGH NCDOT MIGHT REPAIR THE DAMAGE, THERE IS LIKELY NOT ANY LEGAL RECOUSE TO REQUIRE NCDOT TO DO SO.
