The reflectorized area shall have a smooth, sealed encapsulated lens material outer surface. The predominant color for other barricade components shall be white, except that unpainted galvanized metal or aluminum components may be used. Because of their vulnerable position and possible hazard they could create, barricades should be constructed of light 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 with 2 — 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 appear on all plans: "The barricade shall be removed at such time as the need no longer exists, as determined by the Director." If the barricade is within VDOT R /W, a permit is needed for its removal. CHARACTERISTICS Color of stripes Reflectorized red and reflectorized white Width of rail 8" min. — 12" max. Number of reflectorized rail faces 3 if facing traffic in 1 direction 6 if facing traffic in 2 directions This barricade and other traffic barricades are described in the latest edition of VDOT's Work Area Protection Manual Standards and Guidelines and MUTCD.

PROJECT DESCRIPTION THE PURPOSE OF THIS PROJECT IS FOR THE CONSTRUCTION OF THE PRIVATE ROADWAYS BLACKBIRD LANE, SWANSON DRIVE EXT., AND 4TH STREET. THIS PLAN IS WITHIN THE LIMITS OF THE "ALBEMARLE PLACE EROSION AND SEDIMENT CONTROL PLAN, AMENDMENT NO. 3 ", WPO- 200900074 AND THE EROSION AND SEDIMENT CONTROL PLAN SHOWN AS PART OF THE "STONEFIELD BLOCKS F & G FINAL SITE PLAN ". THE SITE DEVELOPMENT PROJECT WILL INVOLVE DISTURBING APPROXIMATELY 21.2 ACRES AND ENCOMPASSES THIS PLAN. THIS PLAN UTILIZES THE EXISTING PHASE 2 NORTH SEDIMENT BASIN CONSTRUCTED WITH THE "ALBEMARLE PLACE EROSION AND SEDIMENT CONTROL PLAN, AMENDMENT NO. 3 ", WPO- 200900074. II. EXISTING SITE CONDITIONS THE SITE HAS BEEN MASS GRADED PER THE "ALBEMARLE PLACE EROSION AND SEDIMENT CONTROL PLAN, AMENDMENT NO. 3 ", WPO- 200900074 AND THE EXISTING CONTOURS ON THIS PLAN REPRESENT THESE CONDITIONS. III. ADJACENT PROPERTIES THE SITE IS BOUNDED TO THE WEST BY RESIDENTIAL DUPLEXES, TO THE NORTH BY SEMINOLE PLACE (FORMERLY COMDIAL), TO THE EAST BY RT. 29, AND TO THE SOUTH BY SPERRY MARINE /NORTHROP GRUMMAN. IV. OFF -SITE AREAS NO OFF -SITE WORK IS REQUIRED FOR THE CONSTRUCTION OF THE ROADWAYS. V. SOILS THIS SITE HAS BEEN MASS GRADED PER THE "ALBEMARLE PLACE EROSION AND SEDIMENT CONTROL PLAN, AMENDMENT NO. 3" WPO# 2009 -00074 AND THE EXISTING CONTOURS ON THIS PLAN REPRESENT THESE CONDITIONS.
