STORMWATER REPORT & CALCULATIONS "
BRIEF NARRATIVE FOR THE PROPOSED RE-DEVELOPMENT PROJECT: THREE (3) HANDICAP SPACES ARE REQUIRED FOR THIS EXISTING PARKING AREA PER ADA AND BUILDING CODES AS MANDATED BY THE SALEM BUILDING INSPECTOR. AFTER MANY DISCUSSIONS OF THE VARIOUS ALTERNATIVES, THE PROPOSED LAYOUT WAS CHOSEN. THE DESIGN WAS FURTHER ADJUSTED AFTER A SITE WALK AND HEARING WITH THE SALEM CONSERVATION COMMISSION. THE AREA FOR THIS
RE-DEVELOPMENT PROJECT IS PARTIALLY LAWN AND PARTIALLY PAVED. THE AREA OF NEW IMPERVIOUS SURFACE IS 1,440 t SF. THE RUNOFF FROM THE PROPOSED PARKING AREA IS DIRECTED VIA A GRASS SWALES TO TWO LANDSCAPED DEPRESSIONS (AREAS A & B) DESIGNED TO CONSERVATIVELY CONTAIN THE FIRST FLUSH (1/2 INCH). IN ADDITION (AS ANOTHER MITIGATIVE MEASURE) TWO MORE LANDSCAPED DEPRESSIONS (C & D) HAVE BEEN PROPOSED TO DETAIN
RUNOFF FROM EXISTING PARKING LOTS. LID MEASURES PROPOSED INCLUDE: (1) NO DISTURBANCE OF WETLAND AREAS, (2) MINIMAL WORK WITHIN 25-FEET OF THE FLAGGED WETLAND RESOURCE AREAS, (3) NO DISTURBANCE OF EXISTING TREES AND SHRUBS, (4) USE OF COUNTRY DRAINAGE WITH NO CURBING OR PIPES, (5) GRASS CHANNELS AND LANDSCAPED DEPRESSIONS. \
1. IN ACCORDANCE WITH DEP STORMWATER STANDARD #1: ALL DISCHARGES SHALL BE TREATED BY PROPOSED LID MEASURES. THE OUTLETS ARE DESIGNED AS LEVEL SPREADERS OVERLAND FLOW THROUGH EXISTING LAWN AND LANDSCAPED AREAS. \ "\
2. IN ACCORDANCE WITH DEP STORMWATER STANDARD #2: PEAK ATTENUATION IS PROVIDED USING FOUR LANDSCAPED DETENTION DEPRESSIONS TO THE MAXIMUM EXTENT PRACTICABLE.
3. IN ACCORDANCE WITH DEP STORMWATER STANDARD #3: RECHARGE IS PROVIDED USING FOUR LANDSCAPED DETENTION DEPRESSIONS TO THE MAXIMUM EXTENT PRACTICABLE.
4. IN ACCORDANCE WITH DEP STORMWATER STANDARD #4: FOR WATER QUAILITY CONTROL MEASURES, THE LONG-TERM POLLUTION PREVENTION PLAN SHALL INCLUDE THE FOLLOWING: (1) YARD/LANDSCAPING MAINTENANCE AND GOOD HOUSEKEEPING PRACTICES FOR THE ENTIRE PROJECT, (2) STORAGE OF MATERIALS INSIDE THE EXISTING BUILDING AND DISPOSAL (OFF-SITE) OF WASTE PRODUCTS, (3) RESTRICTIONS ON WASHING VEHICLES IN THE EXISTING PARKING LOTS, (4)
ROUTINE MAINTENANCE OF THE STORMWATER DEPRESSIONS BY THE LANDSCAPERS (THROUGH THE MANAGEMENT COMPANY) INCLUDING CLEANING AND REMOVING SILT/DEBRIS, (5) SPILL PREVENTION AND RESPONSE PLAN IMPLEMENTED, (6) MINIMAL USE OF NON-ORGANIC FERTILIZERS AND PESTICIDES, (7) SNOW DISPOSAL AND ICE TREATMENT PLAN (SEE BELOW), (8) PET WASTES TO BE CLEANED IMMEDIATELY BY OWNER OF PET, (9) SOLID WASTE REMOVED FROM SITE BY
MANAGEMENT COMPANY, (10) REGULAR STREET SWEEPING IMPLEMENTED BY MANAGEMENT COMPANY, (11) MANAGEMENT COMPANY TO INSURE NO ILLICIT DISCHARGES INTO THE STORMWATER MANAGEMENT SYSTEM AND ASSURANCE OF SPILL PREVENTION MEASURES. IN ACCORDANCE WITH RECHARGE REQUIREMENTS, THE BMP'S HAVE BEEN CONSERVATIVELY SIZED TO CONTAIN THE FIRST FLUSH: 1/2-INCH OF RUNOFF FROM THE HANDICAP PARKING AREA (1,440±SF) WHICH IS T �"
APPROXIMATELY 60t CF. THE THREE LANDSCAPED DEPRESSIONS (ADJACENT TO THE ADDITIONAL PAVED SURFACES) WILL CONTAIN 160± CF.
5. IN ACCORDANCE WITH DEP STORMWATER STANDARD #5: THE PROJECT DOES NOT INCLUDE LAND USES WITH HIGHER POTENTIAL POLLUTANT LOADS. °gRCReSr,
6. IN ACCORDANCE WITH DEP STORMWATER STANDARD #6: THE PROJECT IS NOT WITHIN A CRITICAL ENVIRONMENTAL AREA.
7. IN ACCORDANCE WITH DEP STORMWATER STANDARD #7: THE PROJECT IS A RE-DEVELOPMENT PROJECT WHEREBY HANDICAPPED PARKING IS ADDED TO AN EXISTING PARKING LOT.
8. IN ACCORDANCE WITH DEP STORMWATER STANDARD #8: A SHORT-TERM (CONSTRUCTION PERIOD) POLLUTION PREVENTION AND EROSION AND SEDIMENTATION CONTROL PLAN IS BEING IMPLEMENTED. SEE BELOW. \ O
9. IN ACCORDANCE WITH DEP STORMWATER STANDARD #9: A LONG-TERM OPERATION AND MAINTENANCE PLAN IS BEING IMPLEMENTED. SEE STANDARD #4 AND BELOW.
10. IN ACCORDANCE WITH DEP STORMWATER STANDARD #10: ILLICIT DISCHARGES ARE PROHIBITED AND CONTROLLED/PREVENTED BY SECURITY AND THE MANAGEMENT COMPANY: EAST COAST PROPERTIES.
SHORT-TERM SEDIMENTATION & EROSION CONTROL MEASURES (DURING CONSTRUCTION) O
IN ACCORDANCE WITH DEP STORMWATER MANAGEMENT STANDARD #8 THE FOLLOWING SEDIMENTATION AND EROSION CONTROLS SHALL BE EMPLOYED TO MINIMIZE EROSION (AND TRANSPORT OF SEDIMENT) DOWN-GRADIENT TO WETLAND RESOURCE AREAS DURING THE EARTHWORK AND CONSTRUCTION PHASES OF THE PROJECT: / SITE
1. SILT FENCING: USE A SILT FENCE (DETAIL SHOWN ON THIS PLAN) AT THE DOWN-GRADIENT PROPERTY LINE (INSTALL PER DETAIL). THIS SEMI-PERMEABLE BARRIER MADE OF SYNTHETIC POROUS FABRIC WILL PROVIDE PROTECTION TO MINIMIZE EROSION AND THE RESULTANT SEDIMENTATION TO THE ADJACENT WETLANDS. THE SILT FENCE BARRIER SHALL BE DUG INTO THE GROUND AT LEAST FOUR (4) INCHES AND BE HELD UPRIGHT WITH WOODEN STAKES SPACED TEN
(10) FEET APART (MAXIMUM). THE SMALL SPOIL PILE SHALL BE PLACED ON THE UP-GRADIENT SIDE OF THE SILT FENCE. THE WOODEN STAKES (1.5-INCH SQUARE) SHALL BE DRIVEN INTO THE GROUND AT LEAST EIGHT (8) INCHES. THE SILT FENCE SHALL BE FIRMLY HELD TO THE WOODEN STAKE WITH MANY CONSTRUCTION GRADE STAPLES AND STAINLESS STEEL WIRE. THE SILT FENCES AND HAY BALE BARRIERS WILL BE REPLACED AS DETERMINED BY PERIODIC FIELD OO
INSPECTIONS.
2. VEGETATIIIIIE §1 6PF §TAPILJ2ATI : STABILIZATION OF OPEN SOIL SURFACES WILL BE IMPLEMENTED WITHIN FOURTEEN (14) D0§ AFTER GRADING OR CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED UNLESS THERE IS SUFFICIENT SNOW COVER TO PROHIBIT IMPLEMENTATION. VEGETATIVE SLOPE STABILIZATION WILL 9E US€B TO MINIMIZE EROSION ON SLOPES OF 3:1 (H:V) OR FLATTER, ANNUAL 9RA5595 (5UGH A5 ANNUAL RYE GRASS) HALL DE
USED TO ENSURE RAPID GERMINATION AND PRODUCTION OF ROOTMASS. PERMANENT STABILIZATION WILL BE COMPLETED WITH PLANTING OF PERENNIAL GRASSES OR LEGUMES. ESTABLISHMENT OF TEMPORARY AND PERMANENT VEGETATIVE COVER MAYBE ESTABLISHED BY HYDRO SEEDING OR SODDING. A SUITABLE LOAM TOPSOIL, GOOD SEEDBED PREPARATION, AND ADEQUATE LIME, FERTILIZER AND WATER WILL BE PROVIDED FOR EFFECTIVE ESTABLISHMENT OF THESE O
VEGETATIVE STABILIZATION METHODS. A LIGHT (POROUS) SPREAD OF HAY MULCH WILL ALSO BE USED AFTER PERMANENT SEEDING TO PROTECT SOIL FROM IMPACT OF FALLING RAIN AND TO INCREASE THE CAPACITY OF THE SOIL TO ABSORB WATER.
3. PRIOR TO CONSTRUCTION: PRIOR TO THE PRE-CONSTRUCTION SITE WALK WITH THE SALEM CONSERVATION COMMISSION AND/OR IT'S AGENT), THE SITE CONTRACTOR SHALL BE RESPONSIBLE FOR IMPLEMENTING EACH CONTROL DESCRIBED IN THIS PLAN. IN ACCORDANCE WITH THE NPDES REGULATIONS, THE SITE CONTRACTOR MUST SIGN A COPY OF A CERTIFICATION TO VERIFY THE EROSION CONTROL PLAN AND PERMIT REGULATIONS ARE UNDERSTOOD AND SUBMIT IT PefOOa � r
FOR APPROVAL TO THE SALEM CONSERVATION COMMISSION AGENT AT THE PRE-CONSTRUCTION CONFERENCE. EROSION CONTROLS SHALL BE IN-PLACE PRIOR TO THE PRE-CONSTRUCTION CONFERENCE. ALSO A DETAILED CONSTRUCTION SEQUENCE SCHEDULE OF SITEWORK SHALL BE DISCUSSED IN DETAIL AT THE PRE-CONSTRUCTION CONFERENCE.
4. CONSTRUCTION SEQUENCE: THE CONSTRUCTION SEQUENCE OF STEWORK WILL COMMENCE AFTER ALL PERMITS ARE IN HAND AND A PRE-CONSTRUCTION CONFERENCE WITH THE SALEM CONSERVATION COMMISSION (AND/OR IT'S AGENT) HAS BEEN COMPLETED. AFTER EROSION CONTROL MEASURES HAVE BEEN INSPECTED AND APPROVED BY THE SALEM CONSERVATION COMMISSION (AND/OR IT'S AGENT), EARTHWORK WILL BEGIN TO MOVE EXISTING SOIL MATERIAL AND Re O HOLLOW
COMPACT IN ACCORDANCE WITH MHD SPECIFICATIONS. ONCE THE ROUGH GRADES HAVE BEEN SET FOR THE PAVED AREAS AND ADJACENT LAWNS, THE UTILITIES CAN BE PLACED. THEN FINAL GRADING, THEN PAVEMENT, THEN LOAM AND SEED ALL DISTURBED AREAS WITH HYDROSEED. r� fOO
i
a
5. MAINTENANCE OF EROSION CONTROLS: THE SITE CONTRACTOR WILL BE RESPONSIBLE FOR MAINTAINING EACH CONTROL DESCRIBED IN THIS PLAN. DURING CONSTRUCTION, THE ON-SITE CONTRACTOR WILL INSPECT ALL SEDIMENT AND EROSION CONTROL STRUCTURES WEEKLY AND AFTER EACH RAINFALL EVENT. RECORDS OF INSPECTIONS WILL BE PREPARED AND MAINTAINED ON-SITE BY THE SITE CONTRACTOR. SILT SHALL BE REMOVED FROM WITHIN THE LANDSCAPED
DI IDENTIFICATION. SEDIMENT THAT IS COLLECTED SHALL BE PROPERLY DISPOSED OF OFF-SITE. SPOIL PILES SHALL BE COVERED WITH TARPS AND SURROUNDED BY STAKED HAY BALES. THE SALEM CONSERVATION COMMISSION SHALL APPROVE THE STABILIZED EARTH PRIOR TO THE REMOVAL OF EROSION C o
DEPRESSIONS IF GREATER THAN TWO (2) INCHES DEEP, OR AS NEEDED. DAMAGED OR DETERIORATED EROSION CONTROL DEVICES WILL BE REPAIRED IMMEDIATELY AFTER IDE
CONTROLS.
