Stormwater Outfall Inventory

West Meadow Creek

i: Description Type of Outfall Source of Runoff Discussion/CommentslRecommenclationsI Outfall at Old Field Club Large pipe Road runofffrom West Meadow Road, Mt. Grey Road, The outfall is fitted with a large rubber collar, which opens with the force of stormwater but does not allow tidal water from the creek to flood the street.— Dodge Lane, and residential roads east ofMt. Grey Road. There are numerous storm drains located in the streets; some provide some detentionandthus also act as sediment traps.2. Old Field Club Roof and Decking Small PVC pipe Roof and decking of Old Field Country Club This roofnmoffmay easily be diverted by gutters and leaders to a drywell..i_ Single Family Residence Small pipe The source of flow from this outfall is unknown.4 Horse Corral 1 Small plastic pipe Turf area pitched towards drains in the field. There are grated drains installed in the field, with a possible connection to a pump located at point nimiber 5.

5 Horse Corral 2 Small plastic pipe connected to Turf area and possible connection to storm dram on West Large cement pipe at corner of West Meadow Road and Trustees Road. Not clear if starmwater from this point is directed to outfall, however, assume that—

pump Meadow Road there is the connection to provide worst case scenario.6 Waterview Subdivision Outfall Large concrete pipe Waterview Lane and Dune Court This outf1l is related to a new subdivision, which appears to have a dedicated recharge &e.

-

the outfall is only provided for severe conditions.7 Hillside Road Outfall Small plastic pipe Hillside and Beach Roads This outfall is relatively small for the amount ofroad area and there are nunerous drains/catch basins located at the end ofHillside. It is expected that—

runoffcollects in catch basins located the end ofthis street and that a large poftion ofthe stomiwater is not directed to the outfafl.8 Home Owners Assoc. Boat Ramp Impervious parking area th Soundview Property owners parking lot and boat ramp. A relatively small area of the parking lot is pitched towards the boat ramp. The bulkhead issomeImt deteriorated and the fill has eroded into the creek.steep boat ramp The creek bed in the area suitoundiig the boat ramp is veiy shallow.9 North Road Outfall Large concrete pipe North Road, West Road and part of Baybeny Lane Possible containment in catch basins at end ofNorth Road and towards top of street.

10 Old Woods Road Swale Road end with gully to beach Old Woods Road The end of Old Woods Road was entombed in ice during field inspections. A small metal pipe was observed jutting out of a large pile of snow at the endof the court.

11 Night Heron Drive Outfall Large concrete pipe Night Heron Drive, Wilderness Drive, part of Black Duck This drainage area was identified by the Town Highway Department as a critical point, a Bond Act Application was submitted, with funding approved forDrive and a - connection to Leatherstocking Lane improvements. The Town Division of Environmental Protection should coordinate improvements with the Town Highway Department.12 Boat Ramp 1 on Aunt Amy’s Creek Private boat ramp Portion of lawn area and boat ramp13 Outfall at Aunt Amy’s Creek 2 Large corrugated metal pipes, Lubber Street, Fox Hill Road, Bailey Hollow Road, This outfall has the greatest contributing area by far of any of the outfalls on West Meadow Creek and the greatest number of roadways involved. Thisrip-rap portions of Christian Avenue. Quaker Path, Black Duck drainage area has been the subject of a Bond Act application which is currently under review. The Suffolk County Soil Conservation Service is workingDrive, Woodfleld Road, Mt. Grey Road, Tee Drive, and with the Town Highway Department on this project. The Town Division of Environmental Protection should coordinate improvements with the HighwayHoughton Blvd. Department.14 Boat Ramp 2 on Aunt Amy’s Creek Private boat ramp Portion of lawn area from residential property and

impervious boat ramp area.15 Salt Meadow Subdivision Outfall Large concrete pipe Salt Meadow Lane Outfall is located at the bottom of a slope located in the rear yard of a residence at the end of Salt Meadow Lane (a cul-de-sac).16 Cluistian Avenue Outfall Large concrete pipe Christian Avenue, Valley Road, Chestnut Street, Fallsview There appears to be some containment located in basins in the streets. The outfall is in gool condition, as the photo will indicate, and the discharge pointRoad, part of Ehrland Road and Dale Road is located a fair distance from the surface waters ofAunt Amy’s Creek.17 Dickerson Drive Outfall Small PVC pipe. Dickerson Drive Storm drain located at the end of the road. Dickerson Drive is a narrow road and a resident indicated that the drain and outfall were installed be one of her

neighbors. The discharge point is located far from surface water and there is sufficient area for sediment trapping and use of nutrients in stormwaterdischarged at this point.

18 Ehrland Road Outfall Medium corrugated metal pipe Most of Ehrland Road Storm drains are located towards the end of Ehrland road on the north side. The outfall is located behind house #41. There is a wide area of high marshvegetation between the outfall and surface water.
