The intent of this project is to create 9 one-acre- plus residential house lots . Associated with this project will be the construction of the necessary roadways and utilities to service the proposed homes . Road- ways will include the construction of a new road, Orchard Path Road, 320 in length (to the centerline of the cul-de-sac) .' All lots within the subdivision will be served by public water and sewer . PHYSICAL ENVIRONMENT The site in general consists of lightly wooded rolling terrain with an abandoned section of old Dale Street approximately 1000 ` long, having broken pavement and being relatively flat with a 2%t- grade . The wooded areas are predominently hardwoods with slopes that range from 2`/o to 15% and comprise approximately 70% of the site , northeasterly of the site lies the old cranberry bog, a flat wetland with scattered trees located on hummocks . DRAI i1AGE As indicated in the report for the Coventry Estates Subdivision, the 9 lots of the Orchard Path Subdivision lie within the watershed district. The paved runoff areas from that originally proposed by Coventry have been reduced by 2/3 , and the open areas have been in- creased by 2 lots . However, the retention storage as proposed in the original Coventry Subdivision is the same size area being retained on Lot 1 and provides the same magnitude of storage . A mitigating effect on the development can be realized of approximately 2/3, yielding that as a relative safety factor from the original design. EROSION AND SEDIMENT CONTROL Permanent controls will consist of a retention basin described above, catch basin sumps , rip--rap drainage channels., existing vegetation to remain, landscaping of areas disturbed during con- struction, and the terracing effect created by road and home con- struction. Temporary controls are detailed on the Grading Plans and the notes are included below. --1- E 1 . Baled hay or silt fences shall be installed at the toe of slope of proposed fill areas and at drainage outfalls prior to the start of any excavation or filling. 2. Retention basin shall be constructed as soon as practical and shall be functional prior to installation of the drainage system.. 3 . Bottom of retention basin , shall' be initially constructed to be 12" below the outlet elevation to allow for sedimen- tation. Final grading of the basin shall allow free drainipg. 4. Accumulated silts shall be periodically removed from re- tention basin, catch basin sumps and other erosion control devices . 5 . All non-pavement areas disturbed during construction shall be stabilized with loam and seed, mulch or rip- rap as soon as possible . 6 . Bare earth slopes and soil stockpiles shall be kept to a minimum at all times . Temporary seeding or mulching shall be installed on all bare earth prior to ending construction for the winter and as otherwise necessary. 7 . Roadway areas shall be paved as soon as possible . To the extent practical , roads shall be paved prior to the end of construction for the winter. S . Particular care shall be taken during construction in or near wetland areas to minimize . damage to vegetation . Re- vegetation or other conditions imposed by the Conservation Commission shall be strictly adhered to . SUBSURFACE CONDITIONS Soils on the site are Canton fine sandy foams with Whitman in the wetlands area . Slopes vary 3--8% and 3�15% in limited areas at the east edge of the site where it drops into the lowland. The limitations of Canton soils include stoniness and slope . TOWN SERVICES Traffic -- Total daily traffic generated by this development is expected to be quite minimal . The morning and evening peak hours should have approximately 15 vehicles exiting and entering the subdivision. All traff icy. -2- will reach the development via Dale Street , and we envision no traffic problems created by the develop- ment of this subdivision. Parking - It is estimated that approximately 13 vehicles will be owned by residents of this subdivision, parked in driveways or garages on .each lot . The use of on-- street parking should be minimal . Emergency - Effects on the police and fire departments should be quite minimal . No unusual demand on services should be made by this development . Public Works - This development will add approximately . 06 miles to i� the Town' s road system. This will be a very small demand on maintenance and plowing services , as well as a very minimal demand on the Dept. of Public Works . Education - It is estimated that approximately 36 people Twill occupy this development . Of this number perhaps 13 may be children of school age. Water Sewer The estimated water usage should be approximately 5400 gallons per day and sewage flows should %average 3 , 960 gallons per day. These flows should not put any excess demand on Town systems . SUMMARY This development is small in size with very minimal impact upon the Town and the environment. In fact, the environmental impact is less than that of the originally approved lots created by the Coventry Estates Subdivision with 1000 lineal feet of road providing service to 7 lots , whereas the proposed new road (Orchard Path Road) is 350 lineal feet, providing service. to 9 lots . The proposed new road provides for 2/3 less paving and yields 2/3 more open green space than the originally designed Dale Street . The existing improved Dale Street provides access to 3 lots with little or no impact. ' -3- f !

If you refer to Item 4 -in the Order of Conditions referring to the proposed low point and rim elevations of 119.19 on Sheet 3 (of 5) , that number should read 190.22, now on Sheet #4 of 6. Please advise so that we may make the correction. Very truly yours, .jVi.�.a.,L. Sharon Tuttle JOHN CALLAHAN ASSOCIATES
