Civil Engineers & Land Surveyors 603 Salem Street Wakefield, MA 01880 MITIGATIVE DRAINAGE ANALYSIS EAST PASTURE CIRCLE NORTH ANDOVER, MASSACHUSETTS January 5, 1995 INTRODUCTION This Mitigative Drainage Analysis for the East Pasture Circle subdivision was conducted in order to study the change in runoff potential from the proposed subdivision site, and to design improvements that would be effective in mitigating peak runoff impacts at the points of analysis for the project. To accomplish the goal of the design, the wetland resource area along the limit of the proposed activity on the northerly boundary was selected as the main point of comparison. Other points of comparison are also shown on the plan, and are analyzed for potential development effects. The design approach for this project was to implement sufficient stormwater management techniques within the project site so as to result in no increases in the peak rates of stormwater discharge leaving the subdivision site. METHODOLOGY Runoff which flows from the main portion of the project site travels northerly toward the identified resource area. This Mitigative Drainage Analysis is prepared to analyze the consequence of the proposed development on the existing watershed areas. The hydrological analysis for East Pasture Circle models the watershed under the existing condition. Under the existing conditions, the westerly flow, identified as Watershed A, consists of approximately 0.194 acres, and is noted as Comparison Point 1. The main northerly flow consists of four (4) sub-watersheds, identified as Watersheds B, C, D and E, which comprises approximately 3.5 acres, and is noted as Comparison Point 2. The existing composition of Watersheds B, C, D and E includes a low area in Watershed C in the existing corral area that is piped to the existing man-made ponding area in Watershed D, which then overflows toward Watershed E and the northerly resource areas off site. The northeasterly flow is identified as Watershed P, consists of approximately 3.432 acres, and is designated as Comparison Point 3. The easterly flow is identified as Watershed G, consists of approximately 0.657 acres, and is designated as Comparison Point 4. The existing watershed map shows the overland flow paths to the points of comparison. Under the proposed condition, Watershed A' continues to flow toward the west, however, the impervious area is reduced due to the driveway relocation, shown as Comparison Point 1. The tributary sub-watersheds B', C1', C2', D' and E' are combined to provide the proposed flow to Comparison Point 2. Watersheds B' and C' encompass all of the roadway impervious area, all of the new home driveways, as well as portions of the new home roof areas. This captured flow is directed to a proposed detention basin located on Lot 1 and 2 in Watershed C2% in the vicinity of the existing 10" pipe entrance. The existing pipe is retained, however, a new control structure is added at the top of the proposed detention basin berm to regulate the basin outflow. The impact of this controlled outflow from the proposed basin, shown on the attached Detention �b, ff 15o 101, is It \..Vzo 0 1V Its ID 4-1 d -0 f 49 4 179V/ 461. pp..

The central portion of the site contained by Watershed F in the proposed condition is slightly reduced in area, due to the redirection of the proposed home, driveways and portions of the roofs being redirected to the proposed detention basin. Therefore, the proposed modification of this watershed results in a slight increase of 0.04 cfs for the 1 and 2-year design storms and reductions in the 10 and 100-year design storms, as shown at Comparison Point 3. The balance of the site flow to the east, designated as Watershed G' in the proposed condition, will result in no change from the existing conditions, as shown at Comparison Point 4. A summary of the comparative analysis points for the pre and post development conditions is shown on TABLE III. The results of the comparative analysis indicates that the proposed stormwater management plan for East Pasture Circle is effective for controlling the post development flows and mitigates potential increases due to the increased impervious areas. WATER QUALITY ENHANCEMENT Under the proposed condition, Watersheds B' and C', which encompasses all of the roadway, as well as the majority of the driveway and home impervious areas, is collected via the piped drainage system and discharged to the stormwater management area in the vicinity of the existing shed on Lot 2. The proposed piped stormwater drainage system will include the installation of sumps with gas traps to intercept potential runoff pollutants. The piped drainage is then directed to the proposed stormwater management area, which discharges the street drainage flow to a level spreader rip rap section which diffuses and reduces the velocity of the outflow. The flow then discharges through a crushed stone filter, and overland along the floor of the detention basin approximately 75 feet with a slope of approximately 0.67%. The vegetated basin floor also incorporates three (3) vegetated berms across the basin floor to encourage recharge and contact time. The discharge from the proposed basin then flows through the existing pond in Watershed D' for further enhancement, and then flows overland through established vegetated areas. During construction, and until the proposed detention basin floor has been fully vegetated, a series of temporary hay bales will be installed along the floor to prevent siltation to the downstream resource areas. The proposed rip-rap level spreader area will be over excavated to serve as a temporary siltation basin during construction. The proposed crushed stone filter will be installed and maintained throughout the active construction period. When the temporary hay bales and siltation basin are no longer deemed necessary, the rip-rap level spreader area will be cleaned and shaped to the final grades shown on the plan, and the crushed stone filter will be replaced and cleaned as needed.

The overall design also incorporates acknowledged design techniques to enhance water quality aspects of surface runoff. Therefore, these design features, as well as the implementation of sedimentation and erosion control plan, will result in negligible impacts to the downstream resource areas and/or watersheds. i I 7 1 1 I EXISTING CONDITION ►NATERSHED EAST PASTURE ESTATES NORTH ANDOVER, MA TR-55 CURVE NUMBER COMPUTATION VERSION 1. 11 Project : EAST PASTURE ESTATES User: wrb Date: 01-03-95 County State: Checked: Date: Subtitle: EXISTING CONDITION WATERSHED ASSESSMENT Subarea : A --- - --- Hydrologic Soil Group COVER DESCRIPTION A B C D Acres (CN) ------------------------------------------------------------------------------- FULLY DEVELOPED URBAN AREAS (Veg Estab. ) Open space (Lawns,parks etc. ) Good condition;
