TOWN OF NORTH ANDOVER PLANNING BOARD August 17,2004 Public Meeting Agenda Department of Public Works Conference Room,7:00 p.m. Informal Discussions: Discussion/Waiver: SBA Communications Cell Tower SBA communications is seeking to provide upgrades to an existing cell tower located at 300 Chestnut Street(known as Mills Hill). The tower has been in existence since 1958 and no permitting history exists with the Tower.No increase in height and no additional structures are proposed. The changes are necessary to strengthen the tower. Section 8.9 of the bylaw allows reconstruction, alteration extension or replacement on the site by a Special Permit. Applicant is requesting a waiver as the improvements are internal. See letter addressed to Robert Nicetta for specific changes proposed. Bond Release: Campbell Forest Mesiti Development is requesting release of bonds associated with Campbell Forest. Money was held to ensure the bolts were securely fastened in the weir structures. Work has been completed and Jack Sullivan of DPW has inspected the bolts and recommends release of the$1,000 posted for the bolts. Modification: Peachtree The applicant is requesting to switch the site for the model home. Currently lot 29 contains the model home, however,the developer has an interested buyer who would like to move into the house immediately. The developer is requesting to receive an occupancy for Lot 29, while utilizing the house on Lot 9 for the model home. I found correspondence in files stating the model home was allowed to be released from the covenant prior to several conditions being met. A CO was not allowed to be issued until the road was to binder and the bond was posted. I know there was some history with this lot. Plan Endorsement-1211 Osgood Street-McKlays Applicant has submitted the mylars for the McKlay's retail building. A copy of the MassHighway Permit has also been submitted. The plans display the recently approved modification for the changes in the ingress/egress. I have reviewed the plans which appear to be consistent with the approved plans except for the modification changes. Bond Release: Chatham Crossing Applicant is requesting a reduction of the$222,240 bond posted. DPW is recommending a bond release of$89,300. Keep in mind this subdivision is currently lacking a stormwater management system. Already$100,000+has been released from the originally posted bond. Upon conversations with Jack Sullivan of DPW,he feels the remaining bond amount is sufficient to cover the cost of the stormwater management system. Two single family lots remain to be built on the site, however, the Board did not sign the Form J due to the unresolved drainage issues. Engineering Review Waiver Request-1135 Great Pond Road (Watershed) Brooks School is proposing to construct a screened porch to an existing campus faculty house. The house is located within the Non-Disturbance Zone. Applicant is proposing a.drip stone infiltration trench to mitigate for the stormwater. I have requested that calculations be submitted to determine if the trench has been sized properly. Due to the minor nature of the project,the applicant is requesting a waiver from the outside review. A formal application has been submitted and the project will be heard on September 21, 2004. Minutes Continued Public Hearings: 1789 Great Pond Road-Arnone(Cont. from 7120104)(Continued to August 17,2004) Summary: Applicant submitted an application for a Watershed Special Permit on August 18, 2003 for construction of a new single family house located across the street from Lake Cochichewick within the Non-Discharge Zone and Non-Disturbance Zone. The existing lot was to be serviced from an existing common driveway, however, late into the permitting process it was discovered that the common driveway already serviced two existing homes. The Bylaw does not allow a common driveway to service more than three lots. The applicant was instructed to file for a variance with the Zoning Board of Appeals for access off the existing common driveway. In lieu of filing with ZBA, the applicant has re-submitted a plan proposing a completely separate driveway off Great Pond Road. The plan was forwarded over to VHB for final review and the following comments were highlighted in their March 11, 2004 letter: • Plan should be stamped(progress print was submitted); • The driveway slope ranges from 15%to 12%.The Zoning Bylaw does not have design criteria for driveways,however NM allows driveway vertical profiles ranging from 10%to 15%. A driveway slope of 15% is not desirable but is acceptable by MED. • VHB feels given the horizontal curvature of the proposed driveway in combination with the steep driveway slope, negotiating the driveway will be difficult, especially in winter months. • The plan indicates the driveway will be cut into the existing hill. Surface water will runoff onto the driveway surface and cause a potential ice condition in the winter. Has driveway side treatments, ditches, swales, subdrains been considered. • Applicant should determine site distance along Great Pond Road at the proposed driveway location. • VHB recommends the clay pipes to the west and east of the proposed catch basin be replaced with 12-inch reinforced pipes. Upon discussions with DPW, in order to obtain a DPW driveway access permit, the driveway entrance will have to be regraded(length from roadway to property boundary, approximately 7')so that the pitch does not exceed 3%. Currently approximately 20%pitch. Comments have been forwarded to the applicant. Revised plans have been submitted along with a comment letter from the engineer addressing VHB's previous comments. The following issues have been addressed: • Plans have been stamped by an engineer • Driveway slope ranges from 12%to 15%and a leveling area with a maximum grade of 3%has been designed at the entrance • Driveway has been reduced in width to 12 feet and a 3' infiltration Swale has been added on both sides of the driveway • A 12"reinforced concrete pipe has been proposed to replace the existing 10 inch clay pipe • It appears the grading is in conformance with the slope bylaw requirements as it is just under a 3:1 slope. VHB has reviewed the letter and revised plans and feels all issues have been satisfied. Alberto and Julie conducted a site walk on July 24. The proposed site plan will involve significant clearing and grading within the Watershed District. Access off the common driveway will reduce the amount of clearing, grading and impervious area. It is recommended the applicant further pursue seeking a variance to allow access off the common driveway. No new information has been presented by the applicant.Please review the site individually. 492 Sutton Street-Gianquitto Hanger The applicant is proposing to construct two hangers, one 6,600 s.f and the other 7,000 on a leased 20,078 parcel on the airport property. Applicant has received a variance from the ZBA. The site is located adjacent to existing hanger site. The project will be constructed on previously pervious area. Drainage has not been fully addressed and the applicant must submit additional calculations to address the drainage. VHB review has been completed. At the last hearing the Board requested the applicant to submit drainage calculations.No new information has been submitted to date. 284 Salem Street The project is a refilling of a previously approved project in December of 2001 for reconfiguration of an existing driveway, related landscaping and reduction in size of the existing deck located in the Watershed Protection District. The project was previously reviewed by VHB. The permit has expired and the applicant has not completed the previously approved activities. The applicant has refilled the project with modifications. The applicant presented the modifications before the Planning Board. Additional engineering review was waived with the condition that drainage calcs be submitted by an P.E. See attached detailed review. Upcoming Meetings: September 7,2004 Note: The Planning Board reserves the right to take items out of order and to discuss and/or vote on items that are not listed on the agenda. i i 9
