Nitzsche a. SALEM FOREST III CONDITIONAL APPROVAL Ai�av� The drainage computations are technically correct, however IEP explains the installation of a new 10 ' by 5 ' concrete box culvert will lower the flood stage upstream of .the proposed 0awkins •Lane from elevation 106 . 2 , to elevation 105 .6 . This lower -flood stage will result in a loss of available flood storage in the upstream' meadow of probably more than 15 acre feet. The flood -storage capability of the upstream meadow attenuates flood flows downstream. The loss of available flood storage in that meadow would in all probability increase peak flows downstream not only in the 100 year storm but also in all minor storms. This would, also in all probability, negatively effect the environmental balance . of the existing meadow over a long period of time by lowering of the water surface. In light of the fact that no testimony has been presented to refute this belief, the Planning Board requires the applicant to restore the existing flood stage elevation 106 . 2 and redesign the crossing to assimilate existing conditions in all storms. Further , the drainage computations must be performed by, and signed and stamped by a professional engineer in the proper discipline of Hydrology and Hydrablics. The revised . drainage calculations will include, as a minimum, the topographic . outline of the upstream meadow and its storage capacity as well as an inventory of the wetland plant and wildlife species that may be effected by any change in the existing conditions. 2. The developer shall not place the coat of bituminous pavement until an interim as built and 'certification by the Design Engineer has been submitted and improved by the Planning Board indicating that all utilities have been installed and are correct in accordance with the approved definitive subdivision plans and profiles. ' Said certification will include as a minimum all drainage facilities. 3 . No lot (s) or group of lots shall be released from the statutory covenant until the binder coat of bituminous pavement has been installed and a certification by the Design Engineer has been submitted stating that the pavement is in the correct vertical and horozontal alignment as approved in the Definitive Plan. 4 . The Planning Board recognizes that it would be environmentally .correct in the minimizing of wetland filling and therefore waivers the strict compliance with the rules and regulations in maintaining proper side slopes. The board will require the applicant to increase the side slopes in the area of wetland filling to allow for a 1 to 1 slope provided, however , that a guard rail of acceptable standards be installed in those areas where directed by the Division 'of Public Works. Said guard rail shall be set a distance of six (6) feet . from the gutter line of the roadway and at the top of the slope and provided further that the lto 1 side slope be rip-rapped for erosion control to the satisfaction of the Division of Public Works. This condition shall be incorporated and shown on the Definitive Plans. The applicant shall install three (3) water gates at the C intersection of Patton Lane and Hawkins Lane in accordance with the rules and regulation. , 6 . ' No lots will be released from the statutory covenan until the Conservation Commission and th Board of Health have approved such lot construction And an Order -of Conditions has been issued by the Conservation Commission. 7 . The plans shall be revised to incorporate detail construction specifications for proper installation of the box culverts inluding, but not limited to: time and A / duration of installation, dewatering , base preparation, erosion controls and wing wall construction and will ' include a separate topographic at a scale of 1" to 20 ' of the vicinity of the crossing showing existing and proposed elevations and work with borings and peat depth for approval by the Planning Board and -the Division of of Public Works. V - The applicant shall provide a sepilrate 30 foot wide parcel of land running from Hawkins Lane to the land of the Commonwealth .in the -area between lots 1 and 2 . • Said parcel of land shall be deeded in fee to the Town of North Andover and will be used as a pedestrian access/egress right of' way to the land owned by the Commonwealth. The developer shall not remove any natural vegetation in this parcel -of land during the roadway and/or lot construction without the approval of the Planning Board . Any such removal of vegetation will require the developer to replant and restore the parcel to its natural condition. 9 . The applicant shall show the exisitng stone bounds on Patton Lane and on Granville Lane. �o construction whatsoever will be allowed on Hawkins Lane until Patton Lane has been finished in its entirety to the satisfaction of the Planning Board . and the Division of Public Works,. and a Certificate of Compliance has been issued by the Conservation rj - Commission. 1(1 The plans will not be endorsed by the Planning Board until the status of Parcel 'A' at the intersection of Patton Lane and Hawkins Lane has been resolved to the satisfaction of the Planning Board. No common driveways will be allowed in this subdivision//J° without a Special Permit under the Zoning Bylaws of the Town of North Andover : 13 . The water main and qas ma-i installation shall be shown on the profile of Hawkins Lane in accordance. with the rules - and regulations of the Planning Board. 14 . An additional hydrant shall be installed at the end of the cul-de-sac. 15. All catch basin outlets will discharge on the upstream side of Hawkins Lane. In order to minimize the increased rate of runoff from peak storms, the discharge , from- the catch basins at the intersection of Patton and Hawkins Lanes will empty into a detention pond to be designed and located between Hawkins Lane and land of ' McClung . A. detention drainage easement will be dedicated, 16 . Applicant shall show proposed dwellings, driveways and QN � septic systems along with proposed lot grading to y indicate how each lot will support a habitative area and will not adversely effect abutting properties and other lots within the subdivision.
