Tymon, AICP Town Planner Town of North Andover 1600 Osgood Street North Andover, MA 01845 RE: Application of Brooks School for Special Permit for Installation of Sub Base Drainage System for Synthetic Turf Playing Fields Dear Ms. Tymon: I am writing to follow up on the status of the above application after the Planning Board meeting of July 21, 2009. In particular, since a site visit has been scheduled for August 1,2009 at 9:00 a.m,, I believe that the Conservation Administrator or a representative of the Conservation Commission should be present. As discussed at the hearing,Brooks School is seeking to install a drainage system that would empty into the non discharge zone adjacent to the lake, carrying water into the non disturbance zone. Before this future work can even be contemplated,I believe that the appropriate officials must address the existing problem that was created by the school when it installed a drainage system around the fields last year for which no permit was obtained. A resident of Campion Road brought the problem to the attention of someone last spring. Unfortunately, she is out of town, so I'm unable to contact her and see who is presently investigating the unlawful'drainage into the lake. The site visit should include a look not only at the location of the proposed playing fields,but also a walk down toward the lake to see the magnitude of the destruction that is presently going on. The diversion of the water into the non discharge zone through a drainage pipe has caused erosion from the fields down to the lake. Along the path of the water, it is evident that numerous large trees have fallen recently. The felled trees are in the area where water has been channeled. The trees have come down by the base,and evidence shallow root systems. At the bottom of the hill by the lake, a large tree dam has been erected in an apparent attempt to stop the erosion at that point. Although Brooks' Director of Facilities Management,Mr. Trovage testified that trees are routinely cleared to allow access on the path for cross country runners,this statement is not true as it relates to the area in question. I brought pictures of the dam to the meeting that were shared with the board,and I am hopeful that they can see for themselves that the downed trees were stacked directly where the water reaches the Campion Road abutter's property. He also testified that the water runs along a natural drainage Swale. In truth, a course was dug,and crush stone added, in order to channel the water in its present location. Regardless of how the present issue is resolved with the Conservation Commission, a consultant or perhaps even the Department of Environmental Protection should determine whether a special permit for turf fields within the watershed is appropriate regardless of how they are drained. There is a wealth of information available regarding the toxins that are leached from the rubber tires that are used to construct these fields. In addition,they are disinfected regularly and may contain lead, carcinogenic hydrocarbons, toluene and heavy metals that could find there way into the water supply. I believe that the town should insist upon leachate tests of the water runoff from this type of field. Artificial fields placed above an irreplaceable sole source aquifer may have unpredictable consequences given the proximity to the lake. I am hopeful that given the twelve grass fields presently available at.Brooks School,they will be able to find a way to accommodate both their desire to install turf surfaces,while still providing the town and its residents the assurances necessary that the watershed will not be adversely impacted. I appreciate your time and attention regarding this matter. Very y urs, arlotte S.

Tymon,AICP Town Planner Town of North Andover 1600 Osgood Street North Andover,MA 01845 RE: Application of Brooks School for Special Permit for Installation of Sub Base Drainage System for Synthetic Turf Playing Fields Dear Ms. Tymon: I am writing to follow up on the status of the above application after the Planning Board meeting of July 21, 2009 and the site visit on August 1st. I was hopeful that the Conservation Administrator or a representative of the Conservation Commission would have been present for the site visit as I requested, because I believe that someone who is responsible for the school's compliance with existing drainage and discharge regulations should advise the Planning Board as to the present status of the school's drainage activities. Since my request was not honored, I have reviewed the applicable regulations myself and offer the following. I've reviewed the North Andover Zoning ByLaws,the NACC Wetland Protection Regulations, and the Department of Environmental Protection regulations regarding drainage and discharge in a watershed district. I disagree with your conclusion that Brooks School did not act improperly when they installed the drainage system for the soccer fields last year. Under the Zoning ByLaws, any surface discharge, including "outlets of all drainage swales"in a non-discharge zone is only allowed by special permit of the Planning Board in the Watershed District. The application for such a permit must be accompanied by a written certification by a registered professional engineer, or other scientist educated in and possessing extensive experience in the science of hydrology and hydrogeology, stating that there will not be any significant degradation of the quality or quantity of the water entering Lake Cochichewick. I believe when questioned,you insinuated that a hydrologist would be too expensive for the town to bear,but under the ByLaws, this expense seems to fall on Brooks School. Similarly,the Conservation Commission regulations affirm that no stormwater conveyances may discharge to cause erosion in wetland resource areas of the town. The Department of Environmental Protection regulations make clear that any activity V discharging runoff directly into a watercourse enlarging the volume, rate, or further degrading the quality of existing discharge/runoff is prohibited. Given the clear dictates of these regulations, I do not believe it is prudent for the Planning Board to consider the present application without a resolution of the existing issues. In particular,because the drainage system has created a swale that drains to the lake,I am concerned that the outlet from the proposed system will continue to drain in the damaged area. The proposed drainage channels the water in the path that has been created by the illegal drainage. It is alarming how many trees are falling in the area that the drainage has been discharged. The wildlife is affected as well as the wetlands vegetation, and I believe that someone should sign off on this in their official capacity on behalf of the town. I am hopeful that given the twelve grass fields presently available at Brooks School,they will be able to find a way to accommodate both their desire to install turf surfaces,while still providing the town and its residents the assurances necessary that the watershed will not be adversely impacted. I appreciate your time and attention regarding this matter.

The focus of my review was on stormwater management. The proposed project includes the replacement of two existing natural grass soccer fields with new synthetic turf fields, grandstands and viewing areas. The project is located within the General Zone of the Watershed Protection District. My comments on the application are outlined below: 1. In accordance with the Special Permit Requirements the plans should be stamped by a registered Professional Engineer or Land Surveyor, and the application should include a written certification by a registered Professional Engineer or other qualified scientist stating that there will not be any degradation of the quality or quantity of water in or entering Lake Cochichewick. 2. The drainage system for the existing fields, including the outfall, should be shown on the plans. 3. Site-specific soil testing is needed to determine that there is adequate depth to groundwater for the proposed underdrain system to function as designed. 4. Based on the inverts shown, the 12-inch PVC drains along either end of the proposed Boys Field#2 will not meet the minimum 0.5% slope specified. 5. The flared end section should be designed in accordance with the current DEP Stormwater Handbook, based on the projected maximum discharge velocity. 6. The pipe inverts used in the HydroCAD model are not consistent with the inverts shown on the plan. 55 Old Coach Road Sudbury MA 01776 te[ 508.259.1137 fax 866.82:0.7840 Brooks School Field Renovation, Technical review > June 24, 2009 7. It is not clear whether by using a curve number of 62 in the HydroCAD model the applicant is intending to model surface runoff from the fields, or infiltration through them. If it is presumed that all of the rainfall that falls on the proposed artificial turf fields will be infiltrated, a curve number of 98 should be used to generate the "runoff' flow that is routed through the perimeter drain system. 8. Infiltration through artificial turf fields is generally rapid and, as currently designed, there is no dead storage provided in the underdrain system to attenuate flows or enhance infiltration. I would therefore expect that the proposed design will both shorten the time of concentration and increase the peak rate of discharge from the system. The fact that this is not reflected in the HydroCAD analysis is a function of the analysis, not the design. 9. The plan should identify the erosion and sediment control measures that will be employed during construction to prevent sedimentation into Lake Cochichewick. 10. Finally, the Board should be aware that while artificial turf fields are increasingly popular and do have the benefit of eliminating the need for irrigation, fertilizer and herbicides, a number of other environmental concerns have been raised with respect to their use. The most pertinent of these concerns to this application are the potential for the leaching of zinc from the crumb rubber infill, the "heat island" effect that can result in increased temperatures in the discharge, and the potential need for periodic disinfection of the turf, the runoff from which would be discharged through the underdrain system. You may want to have some discussion with the applicant regarding the products proposed for use at this site and potential mitigation measures. 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, EGGLESTON ENVIRONMENTAL . !1 Lisa D. Eggleston, P.E.
