THE SITE IS LOCATED ON THE NORTHEAST SHORE OF OXOBOXO LAKE AT THE END OF OAKLAND DRIVE. THE SITE WILL HAVE A PRIVATE WELL AND ON SITE SEPTIC SYSTEM.

FINISH LOAM AND SEED - UPON COMPLETION OF SITE GRADING, FINISH LOAMING AND SEEDING OF ALL DISTURBED AREAS. FINAL STABILIZATION OF DISTURBED AND GRADED AREAS SHALL BE FINISHED WITH LOAM AND SEED. LOAM (TOPSOIL AND SUBSOIL) SHALL BE PLACED AT A MINIMUM DEPTH OF 4". A FERTILIZER MIX SHALL BE PROVIDED AS FOLLOWS: FERTILIZER MAY BE APPLIED AT A RATE OF 7.5 LB. PER 1,000 S.F. OF 10-10-10 OR NATURAL (MANURE) FERTILIZERS MAY BE SUBSTITUTED WITH LIME APPLIED AT A RATE OF 180 LBS. PER 1,000 S.F. (4 TONS PER ACRE, OR AS SUGGESTED AFTER SOIL TESTING). THE RECOMMEND SEEDING DATES ARE BETWEEN APRIL 15 THROUGH JUNE 15 AND AUG. 15 THROUGH OCT. 15.

OF ANNUAL RYEGRASS. IN THE EVENT THAT COVER IS REQUIRED FOR STOCKPILES OR FINISHED AREAS OUTSIDE OF NORMAL SEEDING DATES, STRAW MULCHING SHALL BE APPLIED AT THE RATE OF 90 LB. PER 1,000 S.F.. OTHER MULCH MATERIALS USED SHALL BE APPROVED AND APPLIED AT THE RECOMMEND RATES OF THE CONNECTICUT GUIDELINES FOR SOIL EROSION AND SEDIMENT CONTROL MANUAL. MULCH/EROSION BLANKETS: DISTURBED AREAS SHALL BE MULCHED AFTER LOAMING AND SEEDING. MULCH SHALL CONSIST OF .STRAW OR HAY AT THE RATE OF 90 LB. PER 1,000 S.F.. MULCH SHALL BE ANCHORED WHEN DEEMED NECESSARY BY THE TOWN ZONING OFFICER. ANCHORING METHODS SHALL CONSIST OF MULCH NETTING OR ASPHALT SPRAY. SLOPES OF 3h; 1V OR GREATER SHALL BE PROTECTED WITH NORTH AMERICAN GREEN EROSION CONTROL BLANKETS 75 OR EQUAL. SEED BED; SEEDBED PREPARATION WILL CONFORM TO THE STANDARDS RECOMMENDED BY THE CONNECTICUT GUIDELINES FOR SOIL EROSION AND SEDIMENTATION CONTROL MANUAL (REV. 2002). HYDROSEEDING WILL BE PERMITTED ONLY ON SLOPES THAT ARE NO STEEPER THAN 2' HORIZONTALLY TO 1' VERTICALLY. WHERE HYDROSEEDING IS USED TO THE ABOVE SEEDING RATES SHALL BE INCREASED BY 1OX ALL SEEDED AREAS SHALL BE MAINTAINED AND RESEEDED IF NECESSARY UNTIL SUFFICIENT STANDS OF GRASS ARE ESTABLISHED.
