Dennis Yarmouth Intermediate Middle School 296 Station Ave South Yarmouth, MA Proposed Proiect Narrative Purpose The purpose of this RDA filing is to determine proper jurisdiction and delineation of any resource areas on the subject property and to the applicability of the Wetland Protection Act to said property. Existin¢ Site Description The existing site contains the Station Avenue Elementary School, Dennis Yarmouth Regional High School, and the school administration building located at 296 Station Avenue in South Yannouth, MA. The Station Avenue Elementary School is located at 41°40'49.14" N and 70°11'51.30" W, on the northeastern side of Station Avenue in Yarmouth MA. The school is in a residential area and is encompassed by wooded area, particularly to the northwest. Dennis- p Yarmouth High School is located inunediately to the southeast. The facility includes a driveway network and athletic fields servicing the buildings. The school is located in a residential area, surrounded by wooded areas. Currently, most of the stormwater runoff from the site infiltrates into the ground on-site through existing stormwater systems and various existing depressions located within the site. Portions of the perimeter of the site flow in various directions off-site to abutting properties. The on-site areas have been further subdivided for the purposes of hydrological analysis and all areas are described in detail under the Existing Watersheds section of this report. The topography of the site is fairly level, with more moderate slopes from approximately elevation 28 to 35. The majority of the offsite surface runoff flows to the south towards Station Ave. A portion of the site flows toward an existing drainage basin that is the subject of the RDA. This existing basin was designed prior to 1996 and is to be considered an Isolated Land Subject to Flooding (ILSF). Wetland Resource Area (ILSF) An Isolated Land Subject to Flooding area is located on the northwest portion of the property. FEMA Flood Zone The site is not located within a Special Flood Hazard area per FIRM Map Number 25005c006IF, effective date July 7, 2009. No increase in flooding to neighboring areas is anticipated. CDW CONSULTANTS. INC. Dennis Yarmouth Intermediate Middle School 296 Station Ave South Yarmouth, MA Natural Heritage and Endangered Species Progr The Natural Heritage and Endangered Species Program (NHESP) is part of the Massachusetts Division of Fisheries and Wildlife and is responsible for the protection and conservation of endangered species and habitats. After review of the NHESP database and maps, it is evident that no certified or potential vernal pools exist within the project site. In addition, there are no endangered species or priority habitats identified within the project site (see attached figure). Soil Descriptions Existing soil conditions have been characterized by the Barnstable County, NRCS Soil Survey Report, as follows. Map Unit MRCS Soil Map Unit Description Hydrologic Soil Group (HSG) Rating 252A Carver coarse sand A The soil within the project location is comprised of Carver coarse sand which has an HSG rating of A. CDW CONSULTANTS, INC. Dennis Yarmouth Intermediate Middle School 296 Station Ave South Yarmouth, MA Prouosed Prbiect Summar Under proposed conditions, the existing a portion of the parking lot, access drives, and athletic fields will be demolished. A new building will be constructed in the general area of the athletic fields towards the rear of the site along the northwest portion of the property near Bakers Path,, and the parking lot along the front will be reconfigured. A new bus loop road will be constructed that extends from Station Ave, around the Elementary School, around to a drop off area at the front of the school and to the proposed parking lot and continuing down to Station Ave. A looped limited access drive will be constructed around the rear of the school for emergency access. The parking lot will be configured to provide 236 parking spots plus 7 spaces for the administration building. Construction access to the site will be off Station Ave. One Construction Entrance is to be located at the proposed entrance on the east side of the project on Station Ave. There will ultimately be two Entrances on Station Avenue that will provide looped access to the school. New utilities will be brought to the new school, including new force main from the school to the existing treatment plant. The purpose of filing this RISA is for proposed construction activities in the vicinity of the ILSF. The closest proximity of work (grading and clearing) to the ILSF is 36 feet. The closest portion of the driveway is 53'. Developmental Measures; To mitigate increases in runoff from the proposed building, reconfigured parking lots, and overall increase in impervious area, a stormwater infiltration basin and underground stormwater infiltration systems has been provided, capturing both surface flow from the pavement as well as from the roof of the proposed building. Mitigation Measures During demolition and construction, an erosion control barrier will be placed along the site perimeter to protect all adjacent areas, including the ILSF, from erosion and sedimentation. Silt sacks will also be installed in the existing catch basins within 300 -ft of the site. The contractor will be preparing and implementing a Stormwater Pollution Prevention Plan while it is under construction. The location of erosion and control measures are shown on the Demo and Erosion Control Plans included herein. The erosion control measures shall be staked and installed per plan prior to the onset of constriction and shall be inspected daily, and after rainfall events, for integrity and shall be repaired immediately if disturbance or damage has occurred. The contractor shall keep stockpiled material onsite during constriction and until the site has been CDW CONSULTANTS, INC. Dennis Yarmouth Intermediate Middle School 296 Station Ave South Yarmouth, MA fully stabilized. The stormwater management system has been designed with deep sump catch basins, underground infiltration areas with separate filter fabric lined units for enhanced TSS removal. No runoff from the pavement areas of the site are directed toward the ILSF. All captured runoff is infiltrated through the use of raingardens and proprietary stormwater infiltration systems, maximizing stormwater recharge. CDW CONSULTANTS, INC.
