Scott, P.E., Rist-Frost-Shumway Engineering to Re: New Athletic Facility, Brooks School Response to Comments We have received and reviewed the comments by the Board's consultants, VHB, dated 1/29/01 . The following is our response thereto, accompanied by attachments. We use VHBs numbers for reference. VHB Comments: 1 . We are forwarding a set of revised plans, which have been signed and stamped. 2(a). As this is the School's third or fourth submission to the Board in recent years, and the plans are already busy, we would like to skip the locus map. 2(b), No response needed. 2(c). See responses under item #3. 2(d). A retaining wall section appears on one of the construction detail drawings not submitted with the Site Plan Review. A copy of the section is attached. 2(e). Refuse is collected inside the building and will be hauled away regularly. As there will be no concessions or food service in the building, not much refuse is expected. 2(f). We believe the. Narrative in the application covers the traffic issue. 3(a). The elevation of the outlet devices for both detention ponds is set at the pond bottom. If any groundwater enters the pond,it will readily drain. There should never be any standing water in either pond, except during rain events. Nevertheless, a test pit will be performed shortly, and the results forwarded. 3(b). We have checked the discrepancies noted and corrected them. Please note thatthe drainage design has been changed, partly in response to VHB comments, and partly in response to Coler & Colantonio comments on behalf of the Conservation Commission. New calculations have been performed which reflect the changes. The significant changes are: (a) 'Downstream Defender" treatment units have been added, as C&C felt the detention pond does not meet the sediment removal standards,(b)the infiltrators were enlarged to make up fora small deficiency in the recharge trenches at the Maintenance Building, built in '00, (c) the piping at the infiltrators has been revised to assure even distribution of flow and efficient routing of excess flow when they fill, (d)an emergency overflow pipe has been added to the new pond, its crest has been raised and widened slightly, and a small overflow spillway added to the existing pond,and (e)the pond has been stretched southward slightly to make up for the volume lost in raising and widening the berm, RFSSHIMMY Memo to Ms. Heidi Griffin, North Andover Planning Board February 20, 2001 Re: New Athletic Facility, Brooks School RFS 00-4207 Response to Comments Page 2 3(c).1. The small catch basins are modeled with a 2 foot sump; the 4' diameter catch basins are modeled with a 4 foot sump. 3(c).2, 3, &4. The new calculations and drawings have been cross checked; pipe slopes and inverts should agree. 3(c).5. This oversight has been corrected. 3(d), We have added an emergency overflow pipe to the new pond, and a small spillway to the existing pond. 3(e). Their locations have been made clearer on drawing C30 i . 3 ft The pond is no longer counted on fo r sed i m e nt removal,with the addition of Downstream Defenders upstream, 3(g). We have added flared end sections - see drainage notes on drawing C301 . 3(h). Town DPW standards call for drainage systems to be able to handle the 25-Year Storm. HydroCAD output for this storm (included herein) shows no excessively surcharged catch basins, therefore the pipes can hanle the required flow as designed. Indeed, no no new catch basins overflow even in the I 00-Year storm. (The pre-existing catch basin modeled as Pond 40 overflows in the I 00-Year storm - the overflow is routed into the next downstream CB, so the overflow is controlled and accounted for in the calculations). 3(i). The catch basin detail has a note concerning the construction of drain manholes. 3(j). An Operation and Maintenance Plan was filed with the Notice of Intent; a copy of the newly revised plan is attached. 4(a). Only pedestrians and golf carts (for maintenance personnel) will utilize this path. The 7-foot width has been found to be optimal for the School's existing snow removal equipment for pathways. It is not felt that curb or guard rail is necessary. 4(b). The parking lot at the hockey rink is not the only lot associated with the Athletic Facility. There is an existing lot across Main Road from the north end of the Facility which has spaces for 90+ vehicles. There is ample room for the additional handicapped spaces in that lot. 4(c). We believe the Campus Wide Parking Report, which was previously reviewed favorably by Town officials, addresses the parking issues adequately. 4(d). We have added a wheelchair ramp detail has been added. JLS:jdI AS\4207VIGriffin.02200 I.m.wpd cc: Tim Maclntosh,VH13 OPERATION AND MAINTENANCE PLAN Post-Development Stormwater Controls for the New Athletic Facility at Brooks School Stormwater treatment controls for this project consist of pavement sweeping and a pair of "Downstream Defender" stormwater treatment units. There are also deep sump catch basins, an infiltrator installation, and two detention ponds,none of which are not counted towards meeting the removal standard but which remove some sediment and so must be maintained nonetheless. Their maintenance is included herein. Brooks School is the owner of the control devices and is responsible for their operation and maintenance. Pavement Sweeping. All hard surfaced areas on the Athletic Facility site, including drives, parking areas, sidewalks,and plazas should be mechanically swept at least monthly of accumulated dirt and debris. School maintenance personnel will perform this task with the power sweeper owned by the School. Hooded Deep Sump Catch Basins The hood will trap oils and greases by floatation. These should be removed via vacuum prior to removal of sediment and be kept separate. The sediment should be removed via vacuum. Disposal should be to a publically-owned landfill, or other appropriate disposal site which complies with federal and state standards. Frequency of the sump vac operation is best determined in the field after installation. During the first year, the basins should be inspected bimonthly for accumulation. When sediment depth reaches I foot, the contents should be removed. The local Rooter Man franchise, 12 East Dracut St.,Methuen, MA 01844 will perform this task for the school. Downstream Defenders. Th&sump vac should be used to remove captured sediment and floatables. Access ports are located in the top of the manhole. The floatables access port is above the outer annular space between the dip plate and the manhole wall, where floatables are retained The sediment removal access port is located directly over the hollow center shaft which leads to the sediment storage facility below the vortex chamber. Floatables and oil should be removed prior to the removal of the sediment. The frequency of the sump vac procedure is best determined in the field after installation. During the first year of operation, the units should be inspected every 3 months to determine the rate of sediment and floatables accumulation. A probe can be used to determine the level of solids in; the sediment storage facility. This information can then be used to establish a maintenance schedule. When sediment depth has accumulated to 1.5 feet, or floatables depth reaches 6 inches,whichever occurs first, the contents should be removed by sump vac. Although a small amount of water is removed along with the pollutants during the clean out process,the units are typically not completely dewatered. A Downstream Defender with 1.5 feet sediment depth removes 400 gallons of water in the process. Disposal should be to a publically- owned landfill or other appropriate disposal site which meets federal and state standards. The same contractor will perform the vacuum work as for the catch basins. Detention Ponds. Sediment will gradually accumulate in the bottom of the ponds, even though there are effective sediment removal devices upstream. Every year or two, the sediment should be scraped out by machine and disposed of as for catch basin sediment. School maintenance personnel will perform this task. Infiltrators are provided for groundwater recharge,which pick up runoff from a portion of the roof area of the Athletic Facility. Inspection ports are located on the first unit in each group. Every six months, a measurement should be taken at each port of the vertical distance from bottom to grade, and a log kept. If and when sediment accumulation reaches 12", the infiltrators will be excavated, the sediment removed, and the infiltrators reset or replaced. Since the water entering will be clean roof runoff, not much accumulation is expected. Notification. At intervals dictated by the Town, the measurement logs of the catch basins, infiltrators, Downstream Defenders, and detention ponds shall be forwarded to the North Andover Conservation Commission.

A condition was unposed that the detention facilities for the future Athletic Facility would provide sufficient flow attenuation to compensate for the Campus Center/Dining Hall also. Drainage calculations showed that in the 25-Year storm, pre-development peak was 10.03 cfs and post-development peak was 14.97, a positive difference of 4.94 cfs. At the time, the 25-Year event was all that required analysis. These calculations were reviewed by Coler& Colantonio, Inc. and accepted by the Planning Board. In 2000, the new Maintenance Building was constructed. The detention pond for it was constructed in a remote location north of the hockey rink, as there was no room at the immediate site. Drainage calculations showed that in the 25-Year storm, pre-development peak was 23.58 cfs and post-deve lopoment peak was 22.27cfs, a negative difference of 1.31 cfs. These calculations were reviewed by Coler & Colantonio, Inc. and accepted by the Conservation Commission. It is proposed to add a second detention pond east of the hockey rink for the current Athletic Facility project. Therefore, there must be a negative difference of(4.94 - 1.31 = 3.63) cfs or more in order to meet the previously unposed condition. Attached are calculations for the 25-Year event for the Athletic Facility. They show the following: Pre-development Peak 23.59 efs Post-development Peak 18.92 cfs Difference = -4.67 efs As 4.67 is greater than 3.63, the condition is met.
