ALL AQUATIC PLANTS WILL BE PLANTED BETWEEN APRIL 1 AND JUNE 15. 3. IF NECESSARY, THE MARSH ZONES WILL BE DEWATERED 24 HOURS PRIOR TO PLANTING. 4. ALL PLANTS LOCATED IN THE AQUATIC BENCH WILL BE PLANTED IN GROUPS OF LIKE SPECIES. GROUPS OF LIKE SPECIES SHALL BE APPROXIMATELY 200 SQUARE FEET IN AREA.

CONSTRUCTION SEQUENCE 1. ROUGH GRADE TO ELEVATIONS SHOWN ON PLANS. MATERIAL USED FOR FILL SHALL BE FREE FROM ROCKS, ROOTS, MASS OR CLODS. 2. SPREAD TOPSOIL AND WETLAND MULCH IN THE HIGH AND LOW MARSH ZO"""S. GRADE THE HIGH AND LOW MARSH AREAS TO FINAL GRADES SHOWN ON PLANS. 3. PLANT THE HIGH AND- LOW MARSH ZONES ACCORDING TO THE PLANTING PLAN SHOWN ON THIS SHEET. 4. STABILIZE ALL REMAINING AREAS DISTURBED BY CONSTRUCTION. 5. MAINTAIN EROSION CONTROL DEVICES DURING CONSTRUCTION AND REMOVE UPON COMPLETION OF CONSTRUCTION OR ONCE THE DISTURBED AREAS HAVE STABILIZED. AQUATIC PLANTING PLAN 1. RECONFORM ELEVATIONS OF MARSH AREAS AND AQUATIC BENCH ONE WEEK BEFORE PLANTING TO ENSURE PROPER ELEVATION. THE AQUATIC BENCH WILL BE BETWEEN ZERO AND 1.0' BELOW THE NORMAL WATER SURFACE ELEVATION. 2. ALL AQUATIC PLANTS WILL BE PLANTED BETWEEN APRIL 1 AND JUNE 15. 3. IF NECESSARY, THE MARSH ZONES WILL BE DEWATERED 24 HOURS PRIOR TO PLANTING. 4. ALL PLANTS LOCATED IN THE AQUATIC BENCH WILL BE PLANTED IN GROUPS OF LIKE SPECIES. GROUPS OF LIKE SPECIES SHALL BE APPROXIMATELY 200 SQUARE FEET IN AREA. INDIVIDUAL EMERGENT PLANTS WILL BE PLANTED AT A DENSITY OF 18" O.C. SHRUBS WILL BE PLANTED ALONG THE ENTIRE SHORE LINE BENCH AT 4' O.C. 5. PRIOR TO PLANTING, BETWEEN 3" AND 6" OF TOPSOIL WILL BE RESPREAD IN AREAS TO BE PLANTED. IF SUFFICIENT TOPSOIL EXISTS, THE CONTRACTOR WILL PROVIDE WETLAND MULCH SUCH THAT THE COMBINED DEPTH OF TOPSOIL AND MULCH AREAS EQUALS 6". 6. ALL AREAS NOT SPECIFICALLY ADRESSED IN THIS PLANTING PLAN SHALL BE STABILIZED ACCORDING TO THE SEEDING SCHEDULE SHOWN ON THE LANDSCAPE DRAWINGS. �OREBAY SEE VOLUME 1-3.04 VIRGINIA STORMWATER MANAGEMENT HANDBOOK q SEDIMENT FOREBAY EMBANKMENT \ \ \� _- ` ' ' DA I AND DA II = 11.52 AC __ •.. • I Ir .. _ - - -___ / % /'// ` \ ` --- /.//'/'/'/ RIP -RAP I STABILIZED INLET - __ ,if>' / CHANNEL I f / SPILLWAY A A PROTECTION _ �' ; `- "/ ; // L _ _;1' r --'� WESTMINSTER CANTERBURY SITE / FOREBEAY �L NT P. �' '' NORMAL P.U.D. \ -\ WATER 575 SURFACE ELEVATION 6 .' i' �O 'C T& O PLAN VIEW: WATERSHED FOR BIO -RETENTION BASIN FLAN SCALE: 1"=200' STABILIZED ` I I INFLOW \ I / CHANNEL STABILIZED OVERFLOW SPILLWAY .'� � .
