This plan is required to be reviewed by the Planning Board at a public meeting prior to December 7th, 2017. Submittal Standards The material submitted meet the criteria laid out for a sketch plan in §176 -6.3. The Planning Board (Board) will review the proposal and respond to the applicant with comment. There is no vote to approve or deny an application during the sketch plan phase. Plan Set Review The submitted plan contains the necessary information for the Board to provide meaningful feedback to the applicant. Staff is satisfied with the adequacy of the proof plan and is convinced that the submitted proof plan is viable and able to be constructed. Submitted Plans The plan set includes a seven (7) lot conventional subdivision plan depicting a through road from Pelham Road to Eliot Road. The plan set also contains a fourteen (14) unit balanced housing development proposal that consists of twelve (12) structures with two common driveway, one of which will remain open to emergency vehicles as a through way. Staff Comments Staff has reviewed the proof plan for this prospective development and fully agrees with the applicant in the viability of constructing a conventional subdivision on this site. A potential benefit of the conventional subdivision plan would be the construction of a compliant through way between Pelham Road and Eliot Road that would connect the neighborhood north of the site to Town uses south of the site, such as the community center. As the applicant has requested a review and response on a sketch plan the Board should be focusing on the number of units they are comfortable with the applicant proceeding with and /or how the square footage is allocated in a future development. However, in this particular instance staff does not find the proposed balanced housing development as laid out particularly inspiring. Given the location and context of the site the Board may consider alternative options to this balanced housing development, as proposed, such as asking the developer whether he is receptive to exploring a site sensitive development, reworking the balanced housing development based on the Board's comments, or working with the developer to achieve a well- coordinated, conventional G: \Development Administration \Subdivisions \Eliot Road \6 Eliot Road \6 Eliot Road-Staff Summary_2017- 11- 07.Docx Page 2 of 2 subdivision. For some context, the surrounding neighborhood (from Bloomfield Street south to Pelham Road, bounded east to west by Massachusetts Avenue and Highland Avenue, and excluding the properties at 6 Eliot Road and 13 Pelham Road) is currently developed at 1.74 dwelling units per acre. The proposal for 6 Eliot Road, if constructed, would result in a relative density of 4.66 units per acre. For comparison, the conventional subdivision would result in a development of 2.34 dwelling units per acre. While none of these numbers are, in and of themselves, positive benefits or detriments to the proposal they are worth noting in this context for the following reasons: 1. The site is already developed and largely disturbed; 2. The site is highly developable, in that it is an open, flat lot, 3. The historic structure will not, in any scenario, be able to be preserved; 4. The Town will be renovating and reopening an institutional facility quite near the site at 6 Eliot Road. While the relative density being requested by the applicant may seem high, the site is flat, unencumbered, and, more or less, open, making development quite easy. Furthermore, there are few, if any, natural features on the site that have not been disturbed, or would benefit from stringent protection. Therefore, it will be up to the Board, going forward, to work with the applicant to achieve the best site plan possible, knowing the current setting, land configuration, and developability, based on the Board's expertise.

You have provided us with the following two plans showing alternative development of that property: 1. Conventional Subdivision: One plan is entitled "conventional subdivision proof plan" (sheet 3 of 4). This plan shows a dead -end road in the easement area that would serve as access to only three dwellings. A fourth lot fronts on Lincoln Street. No dwellings are located within our easement area. 2. Balanced Housing: One plan is entitled "site construction plan, balanced housing residential development" (sheet 2 of 4). On this plan, only a small portion of the proposed roadway is within the easement area. No dwellings or driveways are within the easement area. You state that while you prefer to develop the site using the balanced housing plan (sheet 2), the Lexington Zoning Bylaws require that before you are permitted to do so, you must satisfy the Planning Board that the development shown on sheet 3, the proof plan (conventional subdivision), is possible. Because of that requirement, you have asked whether the road could be built as shown on the plan entitled "conventional subdivision proof plan" (sheet 3). Our concern is for safety, reliability, integrity and security of our system. We always review requests like yours on a case by case basis, as the circumstances in each case vary. The fact that we allow a certain activity in one area does not mean that we shall allow that activity in another area. We note that there are improvements within the easement area that was previously approved by us under a license agreement, as the location of such improvement at the time of the Company's review and current configuration of our lines did not conflict with our use of our easement. The license granted in no way restricts the Company's future use and enjoyment of its easement rights as it conditions the land owners use of the easement. In response to your specific question, we respond that we would consider the conventional approach as shown on sheet 3, but would require modifications to details before construction. For example, any roadway within our easement must provide adequate clearance between the finished roadway surface and our overhead wires. The precise location and construction of project utilities and drainage system would require our approval, as we have underground rights as well within the entire 250 foot wide corridor. We would make sure that any roadway and utility infrastructure are safely buffered from our structures and utilities cross the easement at 90 degrees. The Company would also evaluate any such proposal to ensure it does not interfere with the Company's likely future exercise of its easement rights. We trust that this letter is sufficient to address the question regarding the hypothetical approval of your conceptual, conventional subdivision plan, so that the Town allows you to proceed with your preferred plan, which we believe is the appropriate approach to your development. Sincer Zfy - eresa M. Feuersange /' pervisor &D Rights nd Su 247 Station Drive SE 210 Westwood Mass 02090 781 -441 -8277 Project Narrative — 443 Lincoln Street Existing conditions - The 4.13 acre site contains a single family dwelling ( #443) near Lincoln Street and a detached multi use service shop (automobile repair) towards the rear line of the lot which are both proposed to be razed. The site is rectangular in shape consisting of four - hundred and fifty feet (450') of frontage along Lincoln Street with a lot depth of four - hundred feet (400'). This 180,000 square foot site is located entirely within the Residential District (RO) and has just two direct abutters. The recently approved "Lincoln Woods" Balanced Housing Development consisting of fourteen proposed units, now under construction, is located to the east and the City of Cambridge Reservoir Land is located to the north, south and west of the site. The structures are respectful of the two- hundred and fifty -foot wide Utility Easement which overlays a portion of the site at an angle from front to back along the westerly side line of the lot in common the City of Cambridge land. The paved driveway and portion of the gravel parking area associated with the service shop are within this utility easement, while the paved driveway serving the dwelling's garage under is located just outside this easement. The existing pavement in the public right -of -way is also greater in width in front of the dwelling to allow for on- street parking. Accessory to the existing dwelling are patios with typical landscaping, retaining walls, fences and lawn areas. A six -foot high wooden stockade fence near the dwelling is also present along the easterly side line of the lot in common with Lincoln Woods. The remaining area outside the easement between the existing structures and along the gravel parking area, is primarily woodland. The area within the utility easement is primarily cleared in fair condition with areas of emerging vegetation consisting of overgrown brush and selective trees Existing utility services - The dwelling and service shop are currently served by a private well and on -site septic system. Future connections to individual town water services and to town sewer services are available within Lincoln Street, according to the Sewer & Water Main Record As -built Plan (RS 708B), dated September 14, 2001. Both the 8 -inch water main and 2 -inch pressure sewer main, which originate from Weston Street to the east, terminate just past the existing service shop driveway to the west prior to the Lincoln Town Line. The pressure sewer main reduces down from a 2 -inch main approximately 200' east of the site. Fire protection is provided by the existing hydrants. Electrical services are both above and below ground to shop. Existing wetland resource areas — Off -site to the north and west is Hobbs Brook which is a perennial stream with associated bordering vegetated wetland and Bordering Land Subject to Flooding. Hobbs Brooks flows under Lincoln Street and into the Cambridge Reservoir to the southwest. Abutting the site to the south are two segments of wetlands bordering on the Reservoir along the opposite side of Lincoln Street. The delineation of these abutting resource areas have been recently confirmed, thru the issuance of an Order of Resource Areas Delineation, by the Lexington Conservation Commission. A portion of the two- hundred foot (200') Riverfront Area measured from the mean annual high water line of Hobbs Brook is present along the rear line of the lot in addition to the one - hundred foot (100') buffer zone which is measured from the edge of the wetlands bordering Hobbs Brook. The outer one - hundred foot (100') buffer zone is also present within the front yard of the dwelling and to the west of the service shop driveway. The Buffer Zone is a Protected Resource Area under the Code of the Town of Lexington for Wetland Protection, Chapter 130. STAMSKI AND McNARY, INC. - 1000 MAIN STREET - ACTON, MASSACHUSETTS 01720 - (978) 263 -8585 Existing stormwater runoff — On -site stormwater runoff drains to Hobbs Brook via sheet flow. A majority of the site drains to a low point behind the service shop to the north, while the runoff from the front of the site drains towards the public street to the south. Runoff within Lincoln Street primarily drains to the west towards Hobbs Brook from a high point near the existing dwelling. According to the NRCS Soil Survey, existing on -site soils consist of Windsor Loamy Sand which is excessively drained and Deerfield Loamy Sand which is moderately well drained. Proposed Project - The proposed Balanced Housing Residential Development will provide a diversity of household types and sizes currently not available within a conventional development at this location. The granting of a special permit by the Planning Board, will permit the construction of four two - family dwellings with open space. Access to the eight dwelling units from Lincoln Street will be provided via a private interior driveway with circular emergency turnaround. Individual driveways will be provided to each two - family dwelling from the interior driveway. The required sixteen (16) parking spaces required per zoning, two per dwelling, will be provided within the proposed garages and individual driveways. Four units will have a two - car garage and the remaining four units will have a one -car garage with a second parking space in front of each garage door. Additional parking is also available for most units within the individual driveways. The interior driveway has been designed to a width of twenty -four feet (24') to allow for proper circulation. Resource Area Improvements — This BHD Plan will remove an automobile shop and gravel parking area from the Riverfront Area. This 18,653 square foot area covers over thirty- percent (30 %) of the on -site riverfront area. The BHD plan will also improve runoff water quality above existing conditions within the riverfront area and buffer zone. Deep sump hooded catch basins, and a proprietary pretreatment unit, Stormceptor or equivalent, will be provided prior to the proposed infiltration basin. The incorporation of native trees and shrubs will also improve the riverfront area. The BHD Plan will also preserve and provide connectivity to open space. The granting of this residential special permit will result in an improvement over the current use as an automobile shop. Proof Plan — The Applicant met last year with the Planning staff on a Conceptual basis to discuss the proof plan and a proposed BHD concept plan. Based on feedback from this meeting, the Proof Plan has been updated to include the proposed grades for the subdivision road option. The BHD Sketch plan has been updated to provide an alternative pavement layout with reduced building footprints provided by the Architect. Proposed utilities — A proposed water main with hydrant from Lincoln Street is proposed within the private interior driveway. Individual water services will be provided from this main to each dwelling unit. A gravity sewer main is proposed to collect sewage from the eight units to a proposed pump chamber along the frontage of Lincoln Street. A central grinder pump with associated controls, storage and emergency generator is proposed for connection to existing pressure sewer main. Sewer design is anticipated to follow approved design preferences of the Town of Lexington. A condominium consisting of the unit owners will be responsible for the operation and maintenance of the private utilities and stormwater controls. The use of the town water and town sewer services will improve protection of the abutting reservoir thru the abandonment of the private well and on -site cesspool.

The first iteration of this plan was discussed by the Planning Board on the evening of April 05, 2017. Submittal Standards The material submitted meets the criteria laid out for a sketch plan in §176 -6.3. The Planning Board (Board) will review the plan set, dated February 03, 2017, and respond to the applicant with comment, as they have done previously. There is no vote to approve or deny an application during the sketch plan phase. Plan Set Review & Staff Comments The submitted plan contains the necessary information for the Board to provide meaningful feedback to the applicant However, the Board did request the following information during the first meeting in April, which has yet to be submitted or addressed: • The applicant must explain how useable the open space is; • The applicant should be prepared to discuss the constraints of the land due to the utility easement on the property, if any; • The parking plan for the balanced housing development proposal must be explained; • The footprint of the abutting, recent development should be provided on the plan set; • The applicant should get documentation from Cambridge identifying what they would allow for salting and snow storage, due to the proximity of the site to the Cambridge Reservoir; • The applicant must explain if the two -foot deep retention basin is adequate, or if it needs to be modified; • The applicant will be responsible for repaving the street if and when utilities are laid out and connected. A paving plan should be provided going forward; and • An answer to the question of what the emission of the power lines, or voltage of the lines, is currently. Submitted Plans Staff reviewed the plans submitted by the applicant The applicant has addressed staff concerns regarding the utility easement on the site. The applicant should be asked to confirm the capacity of the connecting sewer main that will service the proposed site and address how the main will G: \DevelopmentAdmini strati on \Subdivisions \Lincoln Street \443 Lincoln Street \Sketch #2 \443 Lincoln Street-Staff Summary_2017- 11-07.Docx Page 2 of 2 function (i.e., forced or gravity). Other Staff Comments Staff is of the opinion that the design of the proposed balanced housing plan is rather uninspiring as laid out The design, as shown, is not, in staff's opinion, substantially preferable to the conventional subdivision as depicted, but for the reduction in earth disturbance that may be associated with the conventional subdivision. The Board will be tasked with offering constructive comments to allow the applicant to better shape the plan going forward. However, if the comments and concerns listed in this summary, and others to be identified, can be addressed by the applicant to the satisfaction of the Planning Board, staff recommends approving the proposed balanced housing residential development at 443 Lincoln Street The reasoning for this is that the site is already developed and all land on site has been disturbed, potentially contaminated, or encumbered with utilities or buildings. Furthermore, this site has no direct abutters, but for Grey Oaks Circle, making any disruption that could occur during construction very minimal to the surrounding area. Furthermore, the positive increase in the diversity of housing stock within the town is preferable to the construction of four, large single family homes.
