PERIODIC INSPECTIONS BY THE TOWN SANITARIAN WILL BE REQUIRED AS THE FILLING PROGRESSES. 10. A PERMIT FROM THE UNCAS HEALTH DISTRICT IS REQUIRED PRIOR TO CONSTRUCTION OF THE SYSTEM. 11. CONTRACTOR SHALL PROVIDE RECORD PLANS OF THE SEWAGE DISPOSAL SYSTEM, AS BUILT, TO THE UNCAS HEALTH DISTRICT. 2004 McFARLAND -JOHNSON, I10C. These drawings are the prop,e!rty of the Engineer and have been specifically prepared for the owner of this projec!'at this site, and are not to be duplicated or used in port or whole for any other G�rpose, project, location or owner without the expressed written consent of t.ne Engineer. NARRATIVE: THIS PROJECT INVOLVES THE DEVELOPMENT OF A RESIDENTIAL LOT CONSISTING OF HOUSE, WELL, DRIVEWAY AND THE INSTALLATION OF A NEW SEPTIC SYSTEM. THE LOT SIZE IS 14,000 SF (0.32 ACRE). THERE ARE NO REGULATED WETLANDS ON THE PROPERTY. SILT FENCE WILL BE INSTALLED DOWN GRADIENT OF ALL CONSTRUCTION AREAS PRIOR TO CONSTRUC110N. TOPSOIL SHALL BE STOCKPILED ON SITE, SURROUNDED BY SEDIMENT FENCE AND SEEDED WITH RYE GRASS DURING CONSTRUCTION. IT IS THE INTENT OF THESE PLANS TO STABILIZE ALL DISTURBED AREAS AS SOON AS PRACTICABI_L AND ESTABLISH VEGETATION OR INSTALL THE PARTICULAR COVER PROVIDED. ALL MEASURES SHALL BE INSPECTED ON A WEEKLY BASIS BY THE DESIGNATED ON-SITE AGENT. THE CONTRACTOR SHALL CORRECT ANY PROBLEM AREAS OR FAILURES OF THE EROSION AND SEDIMENTATION SYSTEMS. RESPONSIBILITY FOR THE INSTALLATION OF THE EROSION AND SEDIMENTATION PROTECTION AS IDENTIFIED IN THIS NARRATIVE SHALL BELONG TO THE APPLICANT/OWNER. LARRY DANIELS AT (860) 536-0512 IS THE DESIGNATED ON-SITE AGENT RESPONSIBLE FOR ASSURING TO THE TOWN THAT ACTUAL MEASURES TAKEN COMPLY WITH THE CERTIFIED PLAN. WHEN A DIFFERENT INDIVIDUAL BECOMES THE DESIGNATED AGENT, THE TOWN WILL BE NOTIFIED AND ASSURED THAT THE INDIVIDUAL IS ADEQUATELY QUALIFIED TO ACT AS AGENT. THE E & S MEASURES ON THE ENTIRE SITE SHALL REMAIN IN PLACE, INSPECTED BY THE ON-SITE AGENT, AND MAINTAINED BY THE CONTRACTOR UNTIL THE INLAND WETLANDS OFFICER IS SATISFIED THAT THE ASSOCIATED SITE HAS BEEN STABILIZED. SEEDING GUIDELINES: FINAL STABILIZATION OF DISTURBED AND GRADED UPLAND AREAS, UNLESS OTHERWISE NOTED, SHALL BE LOAAED AND SEEDED. LOAM SHALL BE PLACED AT A MINIMUM COMPACTED DEPTH OF 4". RECOMMENDED SEEDING DATES FOR PERMANENT VEGETATION SHALL BE BETWEEN APRIL 1 THROUGH JUNE 15 AND AUGUST 15 THROUGH SEPTEMBER 15. TEMPORARY VEGETATIVE MEASURES SHALL CONSIST OF AN ANNUAL OR PERENNIAL RYE GRASS WITH RECOMMENDED SEEDING DATES BEING FROM MARCH 1 THROUGH JUNE 30 AND AUGUST 1 THROUGH OCTOBER 15. EVALUATE PROPOSED COVER MAMS,,ll�l, BEFORE SPREADING PROPOSED COVER MATERIAL OVER THE DESIGNATED AREA, OBTAIN A REPRESENTATIVE SOIL SAMPLE AND SUBMIT TO A REPUTABLE SOIL TESTING LABORATORY FOR CHEMICAL AND PHYSICAL ANALYSIS. THIS PRELIMINARY TEST IS NECESSARY TO DETERMINE THE REQUIRED INORGANIC AND/OR ORGANIC AMENDMENTS THAT ARE NEEDED TO ASSIST IN ESTABLISHING THE SEED MIXTURE IN AN ENVIRONMENTALLY AND ECONOMICALLY SOUND MANNER. THE RESULTS WILL GIVE THE COVER MATERIAL CHARACTERISTICS SUCH AS PH AND FERTILIZATION NEEDS. THESE RESULTS SHALL BE KEPT ON-SITE BY THE CONTRACTOR AND AVAILABLE FOR REVIEW BY THE TOWN. SEED BED PREPARATION PROPOSED COVER MATERIAL SHOULD BE SPREAD EVENLY OVER THE SITE AREA IN A MINIMUM 4" LIFT VIA BULLDOZER/BUCKET LOADER. USING THE INFORMATION FROM THE SOIL ANALYSIS, CAREFULLY CALCULATE THE QUANTITIES OF LIMESTONE AND PRE -PLANT FERTILIZER NEEDED PRIOR TO APPLYING. PRE -PLANT AMENDMENTS CAN BE APPLIED WITH A BROADCAST AND/OR DROP SEEDER AND INCORPORATED WITH AN OFFSET DISK, YORK RAKE, AND/OR HAND RAKE. AFTER INCORPORATING THE PRE -PLANT SOIL AMENDMENTS, THE SEED BED SHOULD BE SMOOTH AND FIRM PRIOR TO SEEDING. THE FOLLOWING SEED MIXTURES SHALL BE USED AS NOTED: IN 71 1 .4t SEED TIME AND METHOD THE PREFERRED TIME FOR SEEDING THE COOL SEASON MIXTURE IS LATE SUMMER. SOIL AND AIR TEMPERATURES ARE IDEAL FOR SEED GERMINATION AND SEEDLING GROWTH. WEED COMPETIT-10:1 IS REDUCED BECAUSE SEEDS OF MANY WEED SPECIES GERMINATE EARLIER IN THE GROWING SEASON. ADDITIONALLY, HERBICIDE USE IS GREATLY REDUCED. HOWEVER, SEEDING MAY BE DONE AT ANY OF THE AB('V;7 NOTED TIMES. MULCHING NEWLY SEEDED AREAS SHOULD BE MULCHED TO INSURE ADEQUATE MOISTURE FOR SUCCESSFUL TURF ESTABLISHMENT AND TO PROTECT AGAINST SURFACE MOVEMENT OF SEDIMENT -BOUND AGROCHEMICALS AND SOIL EROSION. APPLY GOOD QUALITY STRAW OR HAY AT A RATE OF 2 BALES/100' SQ. Fl. OTHER COMMERCIALLY AVAILABLE MULCHES CAN BE USED.
