Zoning: The zoning of the property is "Industrial 1"This zoning district permits development of the property as proposed herewith. Topography: The topography of the site consists of a hillside sloping at approx. 6% from east to west. This office surveyed the topography by an instrument survey. See attached plan for details. Vegetation: The vegetation consists of mixed deciduous and evergreen trees covering the perimeter of the site. Most of the site is a cleared field. Flood Plain and Wetlands: No portion of the site is within the 100 or 500 year floodplains according to the Flood Insurance Rate Map. The site has been inspected for wetlands and none were found.No rare species or habitat areas are known to be onsite. Drainage/Soils: The drainage pattern on site consists of flow in four directions: from the east directly to Flagship Drive, or to a low point near Flagship Drive - with culverts connecting to the Flagship Drive system, or toward the westerly boundary, or toward the southern boundary. The soils on site are Paxton and Woodbridge, moderately well-draining soils. These soils are suitable for building/road construction and drainage recharge. Utilities: Currently, there are municipal utility services available on Flagship Drive: including water, sewer, gas, telephone and electricity. PROPOSED WORK Generally,the project proposes the construction of an office building with sewer, gas, water and electric connections in Flagship Drive, drainage facilities and necessary grading. The office building would be accessed by way of 2 driveways from Flagship Drive. Topography/Grading: The proposed topography of the site would remain as close to existing grades as possible. Because of the sloping topography, however, there would be a need for retaining walls along the eastern perimeter of the site to reach existing grade before the boundary. See attached plan for details. Parking: The proposed parking would be in conformance with the Town of North Andover code. Drainage: The drainage system was designed utilizing a closed system to achieve reduced rates of runoff at the boundaries of the developed area and would maintain a similar drainage pattern to the existing courses. And in the event of catastrophic storm events, the overflow would be directed into the Flagship Drive system. See the attached Drainage Calculations and maps for further details. Utilities: Proposed utilities on this site include a water, sewer and gas lines connecting to a existing mains in Flagship Drive, and underground electric and telephone lines. Environmental Impacts: Because there are no protected resource areas within or near the subject property,this project is not required to conform to DEP's Stormwater Policy. However, the design described here incorporates many of the Best Management Practices and attains the level of water quality treatment in the policy. As shown in the drainage summary included herein, drainage and runoff characteristics would be controlled in conformance with local regulations, preventing possible damage to abutting property or natural features in the area. The drainage system was designed for severe storms (up to I00-year). Sewage disposal is to be by way of a connection to the municipal system. Thus, there should be no negative environmental impact. In order to safeguard against oil or gas introduction into the drainage system, stormwater runoff from the parking area would be collected into catch basins with oil hoods and deep sumps. (see Site Plan Details). Such pretreatment of stormwater reduces both suspended solids and oils in the drainage system and is recommended by DEP's Stormwater Management Handbook. Another safeguard against future intrusion of contaminants into the groundwater is the implementation of an Operation &Maintenance Plan, which provides further TSS removal and assures proper function of all drainage components. Further safeguards are proposed on the Site Plan to prevent erosion include a line of silt fencing. If all the proposed erosion control devises and procedures are adhered to,then there should be minimal or no damage to neighboring properties from work on this site. Operation/maintenance plan The BMPs associated with this project will be owned by RANGER DEVELOPMENT. If requested, easements can be provided to the Town of North Andover for access to the BMPs for the purposes of inspection, operation and maintenance. Any accumulated sediment should be removed from catch basins, detention trenches and all drainage pipe inlets and outlets as soon as possible after heavy precipitation and every spring. Construction Phase 1) The contractor is to install and maintain drainage facilities as shown on plan(1098,by MHF Design Consultants,Inc., dated April, 2001). 2) All construction of drainage facilities is to be inspected by inspectors from the Town of North Andover and MHF Design Consultants, Inc. to verify conformance to the design plan. Post-Development Phase The owner/occupant is to be responsible for maintenance of all drainage structures in the project - including roof drains, dry wells, drain pipes, and detention trenches. The future owner is expected to be Ranger Development, who will ultimately be responsible for compliance with this O &M Plan. Regular maintenance is to include the following: • Sweeping of parking area after every three months. • Inspection of all drainage pipe inlets/outlets and Detention Basins every three months. • Inspection and cleaning of all Catch Basins every three months or after all severe storms. DRAINAGE SYSTEM ESIGN: The drainage system was designed utilizing a closed system smear drainage pattern to thuced rates of runoff e ffting at the boundaries of the developed area and would maintain courses. The methodology is SCS TR-20, Type III rainfalls (2, 10 & 100-year events). This is consistent with the requirements of the town of North Andover. ad S orrawater pertinent calculations represented in the following pages were developed utilizing My software. The site does not contain any resource areas subject to the Wetlands Prootectio nt Act. Andeas, Flood because none of the proposed work would be within 100 buffer zones, RiverfrPlains, the project is not subject to DEP's Stoma water Management nt Policy. There amount oflthough the drainage system is not required to provide 80/o TSS re aspecific groundwater recharge,we are in fact accommodating a number of Stormwater Management Policy standards with the design presented, as follows: References: 1. SCS- T55(Second Ed., 1986) - for runoff curve numbers. 2. SCS - Rainfall Distribution Maps. 3 DEP -,S'tormwater Policy Handbook The on-site soils consist of Paxton and Woodbridge series, described by SCS as follows: Paxton series (SCS Classification "C") consists of gently sloping to very steep, deep (5+ feet), well drained soils on drumlins.
