This standard section is applicable to subdivisions which are approved for R-C cluster development.This standard section is required on private streets in R-C cluster developments. This standard is notrequired for private streets in a 5— acre subdivision, not subject to the Subdivision Ordinance.Base course is based on a subgrade CBR value of 10. Where CBR is less than 10, 1** of base materialshall must be added for each point below CBR 10. Where CBR is more than 10, subbase may bereduced 1** for each 5 points above CBR-10. All special designs are subject to the approval of theDirector.A 6” Aggregate Base Course, Type I or II is required. The surface course shall must be prime coat anddouble seal surface treatment or prime coat and 100 LB/SY bituminous concrete, Type SM-9.5A.The construction must be inspected by the County.All materials and construction of this design shall must conform to the current VDOT Road and BridgeSpecifications and VDOT Road and Bridge Standards.* Max. % of grade may be increased to 15% for relatively short lengths with the approval of theDirector. Pavement widths shall must be increased to 24* at intersection locations.

** Slope may be increased to 1 1/2: 1 for heights not exceeding 10*, subject to approval of Director.*** See Section 7-0101.3 for easement widths to adjoining properties that are landlocked.

ROADSIDE SIGNKURAL DISTRICT MULTIWAY STOP SIGNS

The "Multiway Stop” installation is useful as a safety measure at somelocations. It should ordinarily be used only where the volume of traffic onthe intersecting roads is approximately equal. A traffic control signal is moresatisfactory for an intersection with heavy volume of traffic.Any of the following conditions may warrant a multiway STOP sign installation.1. Where traffic signals are warranted and urgently needed, the multiway stop

is an interim measure that can be installed quickly to control traffic whilearrangements are being made for the signal installation.

2. An accident problem, as indicated by 5 or more reported accidents of atype susceptible of correction by a multiway stop installation in a 12— monthperiod. Such accidents include right- and left-turn collisions as well asright-angle collisions.

3. Min. traffic volumes:(a) The total vehicular volume entering the intersection from all approaches

must average at least 500 VPH for any 8 hrs of an average day, and(b) The combined vehicular and pedestrian volume from the minor street

or highway must average at least 200 units per hr for the same 8 hrs,with an average delay to minor street vehicular traffic of at least 30seconds per vehicle during the max. hr, but

(c) When the 85-percentile approach speed of the major street trafficexceeds 40 MPH, the min. vehicular volume warrant is 70% ofthe above requirements.

For placement of multiway stop sign identification plates reference the FHWA"Manual on Uniform Traffic Control Devices” .

The predominant color for other barricade components shall must be white, exceptthat unpainted galvanized metal or aluminum components may be used. Because of theirvulnerable position and possible hazard they could create, barricades should be constructed oflight weight materials and have no rigid stay bracing.Planks are to be fastened to posts with 2-3/8” x 6 1/2” carriage bolts and washers or with2-7/16” x 4” lag screws and washers. Bolts and screws are not to be placed closer than 2”from the edge of planks.The following note shall must appear on all plans: ” The barricade shall must be removed atsuch time as the need no longer exists, as determined by the Director.” If the barricade iswithin VDOT R/W, a permit is needed for its removal.
