The subdivision will be serviced by town water and seiner,Addressed. ➢ 4.136 (4)(c)(vii). Projections of down gradient concentrations of nitrogen, phosphorus and other relevant chemicals at property boundaries and other locations deemed pertinent by the SPGA, The applicant has provided written documentation stating proposed activities will not create concentrations of nitrogen,phosphorous and other relevant chemicals on and off site the property. The decision should require that no chemical lawn fertilizers will be used once the subdivision is built VHB Comment: if the use of lawn or garden care products is to be allowed within the non- discharge buffer zone the Applicant should be prepared to submit further evidence regarding down gradient concentrations of any relevant chemicals. Partially Addressed ➢ 4.136 (4)(g). The Bylaw requires that any runoff from impervious areas within the Non- Disturbance and Non-Discharge Zones to the extent possible shall be recharged on site and diverted toward areas covered with vegetation for surface infiltration. The applicant should consider the use of Low.Impact Development techniques to mitigate stormwater runoff. Systems could include vegetated sivales adjacent to the roadway and a rain garden in the middle of the cul-de-sac. These systems would also mitigate the effect of placing a detention system in the Non-Discharge Zone. Partially Addressed Planning Office Comments: The Planning staff.has reviewed the material presented and offers the following comments: ➢ The decision should address the issue of possible fertilizer applications on the lawn area in the finished subdivision so that it does not create concentrations of nitrogen in the area of the property that is in the Watershed Protection Zone. A condition restricting the use of chemical lawn fertilizers may be appropriate. 1600 Osgood Street,North Andover,Mossachusetts 01845 Phone 978.688.9535 fox 978,688.9542 Web www,town0nortbandover,com ➢ Low Impact Development (LID) techniques should be used wherever feasible to minimize the need for a retention/detention structure, as depicted on the plan. This is of special consideration since the proposed retention/detention pond lies within the Non- o Discharge Zone. Please refer to the review of the Definitive Subdivision application for more details regarding recommendations for treatment of stormwater and potential LID techniques. VHB Comments: ➢ There are inconsistencies between the frontages listed for proposed lot's IA and 2A on the plans (sheet 1) and the Application for Watershed Special Permit form. The Applicant should revise accordingly. ➢ On the Application for Watershed Special Permit form it appears that the side setback for existing Lot 2 is listed incorrectly. Additionally the side setback for proposed Lot 2A appears to be listed incorrectly. The Applicant should revise accordingly. ➢ Has the Applicant considered adding guardrail at the edge of pavement along the portion of the cul-de-sac adjacent to the detention basin? i 1600 Dsgood Street,north Andover,Mossadiusetts 01845 Phone 978.688,9535 Fax 978.688,9542 Web www,townofaortliandover.coni i OORTH forth Andover Planning Board O i6E0 N °° 0 Weeting Date- 0 Agenda#: . . 4SS/♦C HLIS PLANNING DEPARTMENT Communiiy Development Division Agenda Item #10 TO: Planning Board FROM: Judy Tymon, Town Planner RE: Definitive Subdivision - The Captain Nathaniel Homestead Applicants--John Cahill DATE: October 3,2008 Proposal: The applicant John Cahill has filed for a four lot Definitive Subdivision consisting of three new lots of 25,000 sq. ft. each and an existing lot containing 32,174 sq. ft. and a new 292 ft.-cul-de-sac on Map 37D, Lot 21 The affected project area is located north of Leanne Drive and west of Marbleridge Road in the R-3 Zoning District. The proposed new street will service only the four lots within the subdivision. The lot will not be further subdivided/developed and no other abutting properties will access the proposed road improvements. The proposal also calls for the construction of a detention/infiltration basin, the installation of underground utilities, the connection to existing water and sewer service, and substantial grading. The applicant's engineer, Philip G. Christiansen., is requesting waivers from the following section of the North Andover Rules and Regulations Governing the Subdivision of Land; • 6.8.1.

Typical sections, details and notes. Addresser) 5.2.6. Test Data -Addressed 5.3 Stormwater Management Report. The applicant has submitted a Stormwater Management Report that will be reviewed by VHB. The following are comments provided by VHB: 1, Section (6.14.2.a): This section requires the drainage system be adequately sized to convey the 25-year 24-hour storm event, Pipe capacity calculations should be provided to demonstrate that the proposed system meets this requirement. 2. Section (6.14.9): This section requires that Total Suspended Solid (TSS) removal calculations be provided. The applicant should provide TSS removal calculations to show that the proposed system will achieve 80% TSS removal. 3. Appendix V—Section(5.f): This section requires a Water Quality Volume be provided for the first 1-inch of runoff fi•om all impervious surfaces. A calculation should be submitted to demonstrate that this requirement has been met. 4. Appendix VI— Section(2.13,10): A note should be added to the plan in accordance with this section to ensure that any un-built lots will be maintained in a stable manner. 5.4 Environmental and Community Impact Statement. NIA 6. Requirements for Improvements and Design The following are comments provided by VHB: 1. Section(6,8.4): The Applicant has provided a profile on sheet 3 showing grade changes to improve stopping sight distance for interactions between vehicles traveling westbound on Salem Street and exiting vehicles fi-om Lydia Lane. Also provided is a calculation demonstrating that this new stopping sight distance will be adequate for design speeds on Salem Street of up to 37 mph. This calculation appears to be correct. Has a speed study been done on Salem Street? If so, what are the existing 85ih percentile speeds along the street? 2. Section (6.9): VHB notes that the Applicant is requesting a waiver from the requirement that at a minimum granite edging shall be provided for all new streets. VHB assumes this roadway may be accepted as a Town way in the future. Granite edging may be appropriate to ensure shoulder erosion is avoided; which could be a future Town maintenance issue. 3. Section(6.11.1). VHB notes that the Applicant is requesting a waiver from the requirement that sidewalks shall be required along one side of the street for all local streets. There appears to be an existing sidewalk along the North side of Salem Street, VHB suggests that a sidewalk along the East side of Lydia Lane could be connected to the existing sidewalk on Salem Street, The Applicant should justify why a sidewalk should not be included in this project, 4. Section{6.12,1): It appears that monuments are not proposed at two (2)property corners of all new lots, as is required by this section. The Applicant should revise the plans as necessary, 5. Section(6.13,3.Vll): VHB notes two separate issues regarding this section's requirements: a. It appears that the proposed drainage easement (accessible from the street)has 3:1 side slopes. This section requires that the side slopes shall be no greater than 4:1. The Applicant should revise the grading in the easement area in order to comply with Town requirements, or request a waiver from this section. b. The section requires the first 20' of the easement from the edge of roadway to have a 12" deep gravel sub-base material beneath the topsoil in order to support maintenance vehicles. The Applicant should revise the plans as necessary to show this, 6. Section(6.15.2): It appears the plans show a proposed fire hydrant. VHB assumes that the Applicant will review fire protection issues with the North Andover Fire Department. 7. Section(6.18.1): VHB notes that the Applicant is requesting a waiver from the . requirement that all new street trees shall be planted within the street right-of-way. It appears the trees are proposed outside the right-of-way in order to avoid utilities. 8. Section(6.24,c): This section requires the planting of low growing plant materials or grass on cut and fill slopes within or contiguous to the street right-of-way. It appears that the plans propose 4" loam borrow to be seeded. The Applicant should verify with the Planning Board that this treatment is acceptable. Planning Office Comments: • The proposed waivers (minimum ROA, minimum street width, granite curbing and location of street trees) seem reasonable for the size of the subdivision—(4 lots), however, the applicant should address the concerns expressed by VHB regarding sidewalks and curbing, The Fire Department should provide feedback to the Planning Board regarding these waivers and their impact on the safety of the proposed road. Both the DPW and the Fire Dept. may require a wider road width to accommodate the turning radius of emergency vehicles. The applicant should be prepared to demonstrate that the proposed roadway width can accommodate the turning radius of the town's safety vehicles. • During a site visit on Monday Sept. 29, 2008, the applicant's engineer indicated that the ROW waiver was requested based on the desire of the applicant to maintain the setback from the existing pool house and that the pavement waiver was requested to protect specific trees. The applicant will be providing a landscape plan and will have a landscape architect at the hearing to discuss the waivers and the proposed landscaping. It would be helpful to demonstrate which trees would be kept with and without the waivers 1 • The applicant is proposing a stormwater detention/infiltration basin at the rear of lot 4. The applicant might want to consider using Low Impact Development (LID) techniques such as a rain garden in the center of the cul-de-sac and vegetated swales on the sides of the roadway to mitigate runoff. These methods may not eliminate the need for the detention basin, however, they will provide for improved on-site infiltration, which is especially important in the Watershed Protection District. At the site visit, the engineer indicated that the island was to be vegetated and that the applicant could propose rain gardens on the individual lots. A relocation of the detention pond was also discussed, with the possibility of switching the location of the pond with the house site for lot 4. • The sight distance improvements on Lot IA include the elimination of an existing retention wall and some regrading. These improvements will result in a sight distance of 275 ft. from the intersection of the new road with Salem St. There is an existing pine tree on the abutters property (188 Salem—Mitchell) whose root system may be disturbed by the re-grading for the sight distance easement. The applicant should consider an altered design to maintain that tree as well as others along the property line that currently serve as a sight buffer. • A portion of the site (rear of Lot 4) falls within the Non-Discharge Zone. The applicant has provided data from the MASS GIS database regarding the location of the wetlands and the Conservation Commission has suggested that the wetlands be delineated to determine the buffer zone. VHB Comments: 1. Will the detention basin have a fence around it? For safety reasons, VHB recommends proposing fences if the pond will be holding water. 2. How is access for maintenance provided for the detention basin? 3. It appears that wheelchair ramps are proposed at the existing sidewalk along the North Side of Salem Street in order to facilitate crossing of Lydia Lane. In accordance with Section 6.11.4 of the Rules and Regulations Governing the Subdivision of Land, the wheelchair ramps shall be ADA compliant. VHB reconunends that the Applicant include a detail in the plans of the proposed wheelchair ramp to be used. 4. VHB notes that a typical trench detail has been provided for both paved and unpaved areas. VHB recommends that the Applicant follow all DPW standards for utility trench work in Salem Street (public-way). 5. Additional spot grades should be provided on the North West (rear) side of the dwelling on Lot 3 to clearly indicate that the finish grade will slope away fiom the dwelling structure.

The proposed road is less than 300 feet long,with a high point located about 175 feet from Salem Street. The maximum grade along the roadway is 3 percent. The area contributing runoff to the roadway is small;just 1.2 acres. All of these factors combined make it unlikely that roadside erosion will be a problem. As is the case in most new subdivisions, particularly where lot sizes are relatively small, the homeowners will maintain the entire right-of-way areas in front of their properties, right up to the edge of pavement. We do not feel that the lack of curbing will create erosion problems. 7. Seetiol! (6.IL I): THB notes that the Applicant is requeslhrg a imdver.f!'oln the regnireinew that sideif,alks shall be required cllong one side of the sireet,fc)1•all local streets.

The Applicant should j?lstifi�1f'Ir��a sideivalkshollld not be inchided in this project, The request for the waiver of the sidewalk requirement is made for three reasons. First, the fact that only four homes will be served by the roadway will result in very low traffic conditions, minimizing the need for the sidewalk for public safety. Second, it is the goat of the applicant to maintain as much as possible the historic nature of the property. A sidewalk would be out of place and unnecessary for this simple, lane like roadway. Third, the project site lies within the Watershed Protection District, and the reduction in impervious area due to the elimination of the sidewalk is consistent with the low impact stormwater management practices encouraged by the Zoning Bylaw.

Andy Melnikas of the Fire Department stating that he has reviewed the plans and requests additional information regarding the distance between the proposed hydrant and the closest existing hydrant in Salem Street. The closest existing hydrant is located adjacent to the southeast property corner of the site. The proposed hydrant is located 480 feet (along the edge of pavement) from the existing hydrant. Lt. Melnikas also recommends that fire sprinklers be installed in each of the homes. No sprinklers are currently proposed, and we are not aware of any regulatory requirement for the sprinklers. The proposed subdivision is located approximately one-half mile from the Salem Street Fire Station. 11.

However, the closest distance between the DEP wetlands line and the proposed limit of work is 295 feet, so even if the wetland line were to change by 140 feet closer to the project, the status of the proposed work would still fall within the Non-Discharge Buffer Zone (150 feet to 400 feet from the wetlands), so the Special Permit Application would be unaffected. We intend to ask Conservation Administrator Jennifer Hughes if she will meet with us at the site to evaluate/confirm the distance to the wetlands. 14.

There is no need for a guardrail in this location. The short length of the road and the alignment of the pavement around the cul-de-sac island will ensure low traffic speeds, and a guardrail would interfere with maintenance access to the detention/infiltration basin. Section 6.19 of the Rules and Regulations Governing the Subdivision of Land states that Guard rails shall be installed in all areas where fill slopes in excess of the required 3:1 have been approved. The proposed slope does not exceed 3:1. Di-carnage Continents 23. Seetion (6.1-1.2a): This section requil•es the drailra e. , tysfew be wlequalely sizecl to conve-*y the 25-vear• 24-hour slm m event. Pipe capacity calculations should be prol'rded to de11 onstrale that the proposeCl,Y.Iwem weets this r'equiremeni, The drainage system was designed to convey the 100-year event, so the 25-year event was not analyzed. Each of the drainage pipes was analyzed as a culvert in the HydroCAD calculations (included in the Stormwater Management Report). The results of the analysis indicate the drainage system has the capacity to convey the 100-year storm. 24. &ctloll (6.141 9): This section requires that Total Susj)ewlecl Solid(TSS) removal calculations hel)rovicle( The crl)j)liccrllt shorticl pr•oi'icle TSS Ivinoval calculatiols to sholl, that the proposed,s;,stem ij'ill achieve 80%removal.

As stated in the Stormwater Management Report, the detention/infiltration basin has been designed to infiltrate all of the runoff that will be generated from storms up to the 10-year event into the underlying soils. The runoff depth produced on the impervious surfaces during a 10-year storm is 4.26 inches. This far exceeds the required 1 inch requirement. 26.

The Applicant has submitted the following information for VHB's review: • Letter to the North Andover Planning Board,including Application for Definitive Subdivision Approval,dated August 21,2008 • Application for Watershed Special Permit and supporting documents I • Definitive Subdivision Plans(6 sheets total),dated July 23,2008 • Stormwater Management Report,dated August 5,2008 • Watershed Special Permit Plan(1 sheet total),dated August 8,2008 '.... The following comments note non-conformance with specific sections of the.Zoning Bylaw,Subdivision Rules and Regulations and questions/comments on the proposed design and VHB's recommendations/ suggestions. Rules and Regulations Governing the Subdivision of Land I. Section(5.2.5.2-6): It appears the Lot Layout Plan(sheet 1)does not list the total lot width for each lot,as is required by this section, The Applicant should add this information to the Lot Layout Plan. 2. Section(5.2.5.3 -22): This section states that a permit for earth removal shall be obtained from the Special Permit Granting Authority prior to submitting the definitive subdivision plans. Has the Applicant applied for such a permit? 3. Section(6.8.1)Table IA:It appears that the intersection(Salem St&Lydia Lane)curb.radii are not labeled. The Applicant should add this information to the plans. 4. Section(6.8.1)Table IA:VHB notes that the Applicant is requesting waivers of the following requirements of Table IA for Local Residential streets: a. Minimum ROW width: 50' (proposed 40') b. Minimum pavement width: 26' (proposed 20') 5. Section(6,8.4): The Applicant has provided a profile on sheet 3 showing grade changes to improve stopping sight distance for interactions between vehicles traveling westbound on Salem Street and exiting vehicles from Lydia Lane. Also provided is a calculation demonstrating that this new stopping 1 r:\092$0 48\dom\memoA0928048-166 Salem St-Definitive Subdivision doc M1 sight distance will be adequate for design speeds on Salem Street of up to 37 mpb. This calculation appears to be correct„ Has a speed study been done on Salem Street? If so,what are the existing 85th percentile speeds along the street? 6. Section(69):VHB notes that the Applicant is requesting a waiver from the requirement that at a minimum granite edging shall be provided for all new streets. VHB assumes this roadway may be accepted as a Town way in the future. Granite edging may be appropriate to ensure shoulder erosion is avoided;which could be a future Town maintenance issue. 7. Section(6.11.1):VHB notes that the Applicant is requesting a waiver from the requirement that sidewalks shall be required along one side of the street for all local streets. There appears to be an existing sidewalk along the North side of Salem Street VHB suggests that a sidewalk along the East side of Lydia Lane could be connected to the existing sidewalk on Salem Street. The Applicant should justify why a sidewalk should not be included in this project. 8. Section(6.12.1): It appears that monuments are not proposed at two(2)property corners of all new lots, as is required by this section. The Applicant should revise the plans as necessary. 9- Section(6.13.3.VII):VHB notes two separate issues regarding this section's requirements: a. It appears that the proposed drainage easement(accessible from the street)has 3:1 side slopes. This section requires that the side slopes shall be no greater than 4:1. The Applicant should revise the grading in the easement area.in order to comply with Town requirements,or request a waiver from this section. b. The section requires the first 20'of the easement frorn the edge of roadway to have a 12"deep gravel sub-base material beneath the topsoil in order to support maintenance vehicles. The Applicant should revise the plans as necessary to show this. 10. Section(6.,15-2): It appears the plans show a proposed fire hydrant. VHB assumes that the Applicant will review fire protection issues with the North Andover Fire Department. 11. Section(6.18.1): VHB notes that the Applicant is requesting a waiver from the requirement that all new street trees shall be planted within the street right-of-way. It appears the trees are proposed outside f the right-of-way in order to avoid utilities.. 12. Section(6-24.c):This section requires the planting of low growing plant materials or grass on cut and fill slopes within or contiguous to the street right-of-way. It appears that the plans propose 4"loam borrow to be seeded. The Applicant should verify with the Planning Board that this treatment is acceptable. Andover Zoning y Town of North Bylaw _,,,,_ 13. Section(4.136.4.c.ii.2):The Watershed Special Permit Site Plan indicates that the wetlands delineation has been obtained from Massachusetts Department of Environmental Protection on-line wetland maps Have these wetland limits been verified with the Conservation Commission? 14. Section(4.136.4.c.vii):If the use of lawn or garden care products is to be allowed within the non- discharge buffer zone the Applicant should be prepared to submit further evidence regarding down gradient concentrations of any relevant chemicals.
