Home My WebLink AboutConsultant Review - 254 GREAT POND ROAD 11/22/2010 Eggleston Environmental November 22, 2010 North Andover Planning Board 1600 Osgood Street North Andover, MA 01 845 Attn: Judy Tymon, Town Planner RE: Watershed Special Permit Review 254 Great Pond Road Dear Ms. Tymon and Board Members: Per your request, I have conducted an initial technical review of the November 3, 2010 Watershed Special Permit Application packet for the above-referenced project, prepared by Christiansen & Sergi, Inc. on behalf of Nancy Leland. The proposed project includes the construction of a new single family home within the Non-Discharge Zone of the Watershed Protection District. My comments on the application are outlined below: 1. As proposed, an existing tennis court that lies primarily within the Non- Disturbance Zone will be removed, and replaced with lawn and garden areas. The proposed house, driveway, and walkways will be constructed totally within the Non-Discharge Zone and will, according to the calculations presented, result in a net decrease in impervious area on the site. From the standpoint of recharge, this should have a beneficial impact on Lake Cochichewick. From a water quality standpoint however, the existing tennis court does not contribute any pollutants to the watershed, while the fertilizers, pesticides and herbicides typically used in landscaped lawn and garden areas are a potential source of nutrients and toxic chemicals. To the maximum extent possible, the project should utilize naturalized landscaping and drought-tolerant native species to minimize the need for watering, fertilizer and chemical application. Consistent with the requirements of the Watershed District, the use of any non-organic landscaping chemicals should be prohibited. Any fertilizer used on the property should be slow-release nitrogen and phosphate-free. 2. It is unclear whether the breezeway, two patios and uncovered walkways are included in the impervious area calculations. It is also not clear whether both the walkways and the patios will be constructed with the porous pavers shown in the detail, as the drawing suggests they are made of different materials. 3. The report narrative indicates that the roof drainage fi•om the proposed house will be infiltrated; however this is not shown on the plan. I note that a good deal of the 55 Old Coach Road Sudbury MA 01776 tel 508.259.1137 fax €366.820.7840 254 Great Pond Rd, Technical Review 2 November 22, 2010 roof area is surrounded by impervious or semi-pervious surfaces, thus drip trenches are not feasible. 4. The report narrative also states that runoff from the asphalt driveway will be treated and infiltrated on site; however there is nothing on the plan to show how this will be accomplished. Based on the apparent suitability of the soils on the site, consideration should be given to incorporating biofilter swales or rain gardens within the landscaping to treat and infiltrate the pavement runoff, or alternatively using porous asphalt for the driveway surface. 5. Construction sequencing should be addressed. Erosion control barriers should be installed prior to any soil disturbance and inspected and maintained throughout the construction phase of the project. 6. The proposed dewatering basin is in the area where the existing tennis court is to be removed. Discharge from the basin should be to a stable, vegetated area. 7. The proposed soil stockpile should be covered or stabilized with temporary seed and mulch. I appreciate the opportunity to assist the North Andover Planning Board with the review of this project, and hope that this information is suitable for your needs. Please feel free to contact me if you or the applicants have any questions regarding the issues addressed herein. Sincerely, EGGLEMN ENVIRONMENTAL - Yfffjjj � Lisa D. Eggleston, P.E.

The responses are provided in the order in which they appear in the Eggleston Environmental review letter. Response to Items: 1. The applicant agrees to the comments offered and will provide the appropriate landscaping and fertilizers. 2. The house, garage, breezeway, and all walks and patios are included in the impervious area calculations. The plans have been revised to eliminate porous pavement. 3. Infiltrators for roof runoff have been added to the plan 4. Driveway drainage will flow westerly through grass which will filter the water and allow infiltration into the soil. The water will flow over a broad area and construction of a swale would only concentrate the flow and reduce the effectiveness of the treatment. 5. Construction Sequence • Install sedimentation control • Provide driveway entrance • Remove the tennis court • Establish the dewatering area • Strip loam • Establish soil stockpile • Excavate the foundation • Backfill foundation • Remove the dewatering area • Build the house breezeway and garage • Install roof infiltrators • Install Patios • Gravel and put binder on driveway • Install trees and shrubs CHRISTIANSEN & SERGI, INC PROFESSIONAL ENGINEERS AND LAND SURVEYORS 160 SUMMER STREET, HAVERHiLL,MA 01830 cs�li tel:978-373-0310 mm.csi-engrxom Says 978-372-39610 • Loam and seed disturbed areas • Place top course on drive • Remove sedimentation control 6. The test pits dug on site show the soil under the tennis court is sand and suitable for rapid infiltration. It is an excellent site for a dewatering pit. Additionally the area beyond the tennis court is grass and water that escapes will flow over the grass. 7. The Stockpile will be covered if it remains longer than three months The proposed project will result in a decrease in overland storm flow from the site. Additionally infiltration of roof runoff will further lessen the runoff. Runoff from the driveway will flow through a lawn at a low velocity and allow suspended solids to be removed. The project as designed and improved by the Eggleston Environmental review meets all criteria for designing in the Watershed Protection District. Very truly yours Philip G. Christiansen P.E.
