Prepared for West Side Hangar Association 236 Swains Pond Road Melrose, MA 02176 May 1, 2002 INDEX Statement of Compliance with Section 5.4.4,Rules and Regulations Governing the Subdivision of Land: Environmental and Community Impact Statement Hydrologic Analysis for Hangar Expansion Lighting Specifications Building elevation plan e Environmental and Community Impact Report For WEST SIDE HANGAR ASSOCIATION LAWRENCE AIRPORT j 5.4.4.1 Natural Environment a. Air and Noise Pollution - The site is presently operating as an airport. The proposed structures are for aircraft storage and will not increase existing levels. b. Water Pollution The development generates a zero increase in runoff from pre to post development conditions. Domestic sewage will flow into the Tawn's sewer system and to the sewage treatment plant before discharge to the Merrimack River. C. Land - There will be no removal of soil from the development site; the only soil brought in will be the processed gavel for the pavement base. There will he sedimentation control devices in place and an erosion and sedimentation control plan d. Plants &Wildlife- There are no protected species or habitats listed in the state's Natural Heritage Atlas located on or in proximity to the development. e. Water Supply- The development is serviced by municipal water and will have no demand on ground water. The stormwater management systenr as designed will keep past-development peak runoff rates equal to or less that? the pre-development peak rates far the 1, 2, 10, 25, and 100 year storm event. See attached;Hydrologic Analysis ,. f. Sewage Disposal— The development is serviced by municipal sewer and will have no effect on ground water. 5.4.4.2 Man-Made Environment a. Existing Neighborhood Land Use- The site is currently an airport with an abutting residential district., The proposed structures are compatible with the surrounding environment. b. Zoning- The development was granted a variance far expansion of a non-conforming use on Dec. 12, 2001. 5.+4.4.3 Public Services a. Schools- There will be no additional students in the system, b. Police- The project by itself will not require the hiring of additional police. —page 1 1 C. Fire- 7he project has adequate municipal water and pressure to fight fires. Buildings}will have smoke alarms and sprinklers as required by the North Andover Fire Dept, d. Recreation - On-site recreational facilities are not proposed. e. Solid Waste Disposal - Solid waste generated by the project after-construction will be collected by a private waste disposal.f r m. f. Traffic- The anticipated traffic generated by this project will be extremely minimal. There will be a total of four aircraft housed within the facility and only eight parking spaces are provided It is anticipated that pilots and passengers will occupy these spaces. The intervals between arrivals and departures should be considerably long in duration, g. Highway - The present use of roads by heavy trucks and equipment traveling to and from the site will not be increased except during the construction phase. 5.4.4.4 Aesthetics a. Lighting- Yhe lighting proposed,far the project will be wall mounted and spaced at a maximum 40 foot intervals at a height of 10 to 15 feet. One hundred watt lamps will be used when Avo buildings face each other and one hundred and fifty watt lamps will be placed where areas are lighted from only one side. Refer to the site plan for light fixture placement. Specifications for the lighting are attached b. Landscaping - The site will remain in its natural state outside of the areas disturbed for construction. C. Visual- The visual impact of this project will be minimal because it will be buffered by the existing BVW which exists behveen the site and abutting residential. 5.4.4.5 Planning One must assume that the current zoning conforms to the master plan. Because the project conforms to Zoning, it conforms to the master plan. { ^page 2 Hydrologic Analysis for Hangar Expansion i I HYDROLOGIC ANALYSIS FOR WEST SIDE HANGAR ASSOCIATION LAWRENCE AIRPORT A stormwater analysis was performed on the hangar expansion proposed by West Side Hangar Association at the Lawrence Airport, The existing and proposed conditions were analyzed for the site to determine the fate of stormwater runoff. The areas analyzed, the sail types for the analysis and the detailed calculations are attached. The results, which are summarized below, show that, if the project is built as proposed, there will be no increase in off site peak stormwater runoff. 1 YEAR STORM 2-YEAR STORM 10-YEAR STORM 100 YEAR STORM PEAK FLOW(CFS) PEAK FLOW(CFS) PEAK FLOW(CFS) PEAK FLOW(CFS) EXISTING PROPOSED EXISTING PROPOSED EXISTING PROPOSED EXISTING PROPOSED .60 .47 .92 ,88 1,91 1.38 3.40 2.53 / . / / -142---- -- - LONGEST FLOW PATH ks ON40 N - _�� PLAN OF EXISTING DRAINAGE CONDITIONS SCALE, 1" = 50' DATE' NOVEMBER 10, 2000 25 0 25 50 FT ENCI CHRISTIANSEN gj,SERGI RROLANDONAL SURVEYORSEERS 160 SUMMER ST.
