B.FOLLOWING CONSTRUCTION, THE BIORETENTION BASINS SHALL BE INSPECTED EVERY SIX MONTHS AND/OR AFTER STORM EVENTS OF 2 INCHES OF RAINFALL OR GREATER. INSPECTIONS SHALL INCLUDE THE FOLLOWING: ·INSPECT FILTER MEDIA STANDING WATER OR OTHER EVIDENCE OF CLOGGING. ·CHECK FOR SEDIMENT ACCUMULATION, TRASH, AND DEBRIS. ·CHECK FOR BLOCKAGES, STRUCTURAL INTEGRITY, AND EVIDENCE OF EROSION AT INLET, OUTLET, AND OVERFLOW SPILLWAY. C.REGULAR MAINTENANCE SHALL INCLUDE THE FOLLOWING: ·BASIN FLOOR/SIDE SLOPES SHALL BE MOWED 6" TO 8" AS NEEDED. GRASS CLIPPINGS, LEAVES AND ACCUMULATED SEDIMENT ANDDEBRIS SHALL BE REMOVED DURING THE SUMMER, HOWEVER, PLANT MATTER SHALL BE LEFT IN PLACE OVER WINTER MONTHS TO INSULATE THE SOIL AND ADD ORGANIC MATTER TO THE SOIL. REMOVAL CRITERIA SHALL INCLUDE WHEN PLANT MATTER IS SMOTHERING OR KILLING VEGETATION AND AESTHETICS. ·REMOVE SEDIMENT GREATER THAN 1.0 INCH DEEP IN MARCH-APRIL IN THE FILTER MEDIA BED IN A MANNER TO MINIMIZE DAMAGE TO VEGETATION. ·INSPECT SOIL AND REPAIR ERODED AREAS SEASONALLY OR AS NECESSARY. ·REMOVE ANY INVASIVE SPECIES (INCLUDING ROOTS) THAT HAVE BECOME ESTABLISHED WITHIN THE BASIN AND EMBANKMENTS. ·IF THERE IS AN ACCUMULATION OF ORGANIC DEBRIS OR SEDIMENT ON THE FLOOR OF THE BASIN, OR IF PONDED WATER IS REGULARLY OBSERVED MORE THAN 48 HOURS AFTER A RAINFALL EVENT, THE TOP 6" SHALL BE REMOVED AND THE EXPOSED SOIL SURFACE ROTOTILLED TO A DEPTH OF 12". SEDIMENTATION SHOULD BE REMOVED WHEN IT IS VISIBLY DRY AND READILY SEPARATES FROM THE BASIN FLOOR TO MINIMIZE SMEARING. AFTER THIS WORK HAS BEEN DONE, THE BOTTOM OF THE BASIN SHALL BE RESTORED TO ITS ORIGINAL CONDITION. ·NO PESTICIDES OR NON-ORGANIC FERTILIZERS SHALL BE USED IN AREAS DRAINING TO THE BIORETENTION BASIN. STORMWATER MANAGEMENT SYSTEM MAINTENANCE PLAN: 1.GENERAL A.PAVEMENT SWEEPING SHALL BE PERFORMED AT LEAST ONCE PER YEAR, PREFERABLY AT THE END OF THE WINTER SANDING SEASON AND IN CONJUNCTION WITH INSPECTION AND CLEANING OF ALL STORM DRAINAGE STRUCTURES AND FEATURES. 2.CATCH BASINS AND MANHOLES A.A CONNECTICUT-LICENSED HAULER SHALL PUMP THE SUMPS OF ON-SITE CATCH BASINS AND MANHOLES, AND SHALL DISPOSE OF THE PUMPING LEGALLY.

B.FOR THE FIRST 2 YEARS, EACH CATCH BASIN SHALL BE INSPECTED EVERY 4 MONTHS, WITH ONE INSPECTION OCCURRING DURING THE MONTH OF APRIL. ANY DEBRIS OCCURRING WITHIN 1-FT. FROM THE BOTTOM OF EACH SUMP SHALL BE REMOVED BY VACUUM “VACTOR” TYPE OF MAINTENANCE EQUIPMENT. AFTER THE FIRST 2 YEARS THE INSPECTION SCHEDULE MAY BE ADJUSTED TO MEET ACTUAL OPERATING CONDITIONS, HOWEVER, ONE INSPECTION SHALL ALWAYS BE CONDUCTED IN APRIL. ALL SEDIMENT SHALL BE DISPOSED IN ACCORDANCE WITH ALL RULES AND REGULATIONS OF THE CT DEEP. GENERAL NOTES: 1.THE APPLICANT IS MT KINEO BUILDERS, LLC WITH A MAILING ADDRESS OF P.O.

THE PARCEL WAS CREATED AS PART A SUBDIVISION APPROVED IN OCTOBER 2016. AS PART OF THE RESUBDIVISION, THE ROADWAY, ASSOCIATED ROADWAY DRAINAGE SYSTEM, STORMWATER MANAGEMENT IMPROVEMENTS, AND COMMON UTILITIES (SANITARY SEWER, ELECTRIC, TELEPHONE, CABLE) WILL BE INSTALLED. THE RESIDENCES, DRIVEWAYS, INDIVIDUAL LOT GRADING, AND DRILLED WELLS SHOWN ON THE PLANS FOR THE NEW BUILDING LOTS ARE SHOWN FOR CONCEPTUAL PURPOSES ONLY. NO LOT DEVELOPMENT IS PROPOSED AT THIS TIME. PRIOR TO ANY INDIVIDUAL LOT DEVELOPMENT, A SITE PLAN SHALL BE PREPARED IN CONFORMANCE WITH ALL APPLICABLE LOCAL REGULATIONS, AND REVIEWED AND APPROVED BY THE ZONING ENFORCEMENT OFFICER. THE DEVELOPMENT OF INDIVIDUAL LOTS SHALL NOT ADVERSELY AFFECT THE DEVELOPMENT OF NEWLY CREATED LOTS OR EXISTING ABUTTING PROPERTIES. 2.CONSTRUCTION IS ANTICIPATED TO COMMENCE IN FALL 2025. CONSTRUCTION WILL OCCUR IN TWO PHASES. PHASE ONE WILL INCLUDE THE CONSTRUCTION OF THE ROADWAY, ASSOCIATED ROADWAY DRAINAGE SYSTEM, STORMWATER MANAGEMENT IMPROVEMENTS, AND COMMON UTILITIES. PHASE ONE IS ANTICIPATED TO START FALL 2025 AND END BY FALL 2026 (~1 YEAR DURATION). PHASE TWO WILL INCLUDE THE CONSTRUCTION AND BUILD OUT OF EACH BUILDING LOT WITH A HOUSE WHICH WILL OCCUR AS EACH LOT IS SOLD. PHASE TWO IS ANTICIPATED START FALL 2026 AND END WINTER 2030 (~5 YEAR DURATION). IT SHOULD BE NOTED PHASE TWO IS NOT PART OF THE SCOPE OF THIS PROJECT AND NO LOT DEVELOPMENT IS PROPOSED AT THIS TIME (SEE NOTE #1 ABOVE). THE EXACT START AND END DATES OF PHASE TWO MAY VARY DUE TO VARIOUS FACTORS SUCH AS THE HOUSING MARKET, INTEREST RATES, ETC. 3.EXISTING TOPOGRAPHY ACROSS THE SITE IS MODERATE TO STEEP WITH ELEVATIONS RANGING FROM 416± ALONG THE WESTERN PROPERTY LINE, TO326 AT THE WETLAND IN THE SOUTHEAST CORNER. PER NRCS SOIL MAPPING, THE UNDERLYING SOIL ACROSS MOST OF THE SITE CONSISTS OF WOODBRIDGE FINE SANDY LOAM (HYDROLOGIC SOIL GROUP 'C/D'). RUNOFF FROM THE SITE EVENTUALLY FLOWS TO ROCKLAND POND LOCATED APPROXIMATELY 0.2 MILES EAST/NORTHEAST OF THE SITE 4.APPROXIMATELY 4.65± ACRES OF THE 19.5± ACRE PARCEL WILL BE DISTURBED BY EARTHWORK ACTIVITIES FOR THE CONSTRUCTION OF THE ROAD AND STORMWATER MANAGEMENT IMPROVEMENTS. THE PROJECT DEVELOPMENT WILL REQUIRE DEMOLITION, CLEARING AND EARTHWORK TO PREPARE THE SITE. EARTHWORK ACTIVITIES WILL EXPOSE SOILS TO EROSION DURING RAINFALL EVENTS 5.THE INTENT OF THIS SESC PLAN IS TO ESTABLISH STORMWATER MANAGEMENT CONTROLS DURING CONSTRUCTION TO PREVENT THE DISCHARGE OF SEDIMENT LADEN RUNOFF FROM ENTERING STORM DRAIN SYSTEMS OR ADJACENT PROPERTIES. 6.REFER TO INLAND WETLAND REPORT (UNDER SEPARATE COVER), STORMWATER MANAGEMENT REPORT (UNDER SEPARATE COVER), TEST HOLE LOGS (SHEET 16 OF 16), PERMEABILITY TEST RESULTS (SHEET 16 OF 16), AND STORMWATER MANAGEMENT IMPROVEMENTS AND DETAILS (SHEET 7 AND 16 OF 16). LOW-IMPACT DEVELPOMENT FEATURES INCLUDE MULTIPLE STORMWATER MANAGEMENT BASINS, AN INFILTRATION TRENCH FOR WATER, VEGETATED SWALES, AND DISCONNECTED IMPERVIOUS AREAS. GENERAL SESC REQUIREMENTS 1.THE SITE CONTRACTOR MUST FOLLOW ALL GUIDELINES SET FORTH IN THE MANUAL ENTITLED "CONNECTICUT GUIDELINES FOR SOIL EROSION & SEDIMENT CONTROL," EFFECTIVE DATE: MARCH 30, 2024, PUBLISHED BY THE COUNCIL ON SOIL AND WATER CONSERVATION IN COLLABORATION WITH CONNECTICUT DEPARTMENT OF ENERGY AND ENVIRONMENTAL PROTECTION. 2.SESC MEASURES INTENDED TO MINIMIZE SOIL EROSION AND TO CONTROL SEDIMENTATION DURING CONSTRUCTION INCLUDE: A.THE INSTALLATION OF SILT FENCE ALONG THE DOWNGRADIENT LIMIT OF DISTURBANCE.
