************ ADMINISTRATION OF LAND DEVELOPMENT REGULATIONS *************
SUBDIVISION OF LAND
Public Information Meeting, Lexington Hills Conventional Subdivision Revised Preliminary Plan (off
Walnut Street, part of the former Middlesex County Hospital site): Present for the development team
were Mr. Joseph Lerman and Mr. Habib Aminipour, August Realty Trust, applicants; Mr. Gary Larson
and Mr. Ti Johnson, landscape architects, Larson Associates; and Mr. Edmund Grant, attorney.
Mr. Larson presented a plan that he indicated responds to the Board's comments on the previous
preliminary plan, reviewed on January 4, 2006, as follows: the context map includes the development
across the Town line in Waltham; the amount of impervious surface is less, due to smaller house
footprints and two-car garages instead of three; and, the communications tower is on a separate lot of a
size to satisfy safety concerns, 90 feet from the Town line with a planted buffer. The plan is now for 18
lots, as one lot was lost in order to accommodate the size of the lot for the communications tower. Mr.
Larson said that he measured the sight distances at the intersections of proposed roadway with Walnut
Street, and in both directions on Walnut Street he found they exceed AASHTO parameters of 200 feet.
The sewer will connect into the town system in Walnut Street via gravity feed to a pump station. He noted
that all utilities are in Walnut Street.
Changes in the stormwater management system allow the drainage system to handle all runoff on the
property even though the designers have reduced the size of the system's underground structures. The
dwellings will each have dry wells for roof runoff, which allowed the reduction in the size of the
infiltration system. Erosion control measures will be applied to all slopes over 3 percent. Mr. Larson
explained why creating a vehicle easement to Lot 1 is impractical, citing in particular the 40-foot grade
change which would make construction of any roads financially infeasible, It could result in the loss of up
to two lots in the Lexington Hills subdivision. There would be significant site disturbance to
accommodate a 12 percent grade for the road. In addition, the presence of a vernal pool on Lot 1 would
prohibit permitting of the road.
Minutes for the Meeting of February 2, 2006 2
Board Questions and Comments
:
The sight distances on Walnut Street are a major consideration. At the definitive stage, the Board will
require a peer review of the applicant's traffic analysis of Walnut Street, which should determine whether
Walnut Street is a collector street or an arterial street. The grade where the new road meets Walnut Street
should be reduced for at least 75-feet from the intersection.
At the definitive stage, the Board would like to see a pedestrian access to Lot 1, if possible, as it is part of
the Western Greenway.
Mr. Hornig had questions about the sewer system pumping station. His concern is that it be set back from
the Walnut Street right of way in case the street is ever widened or a sidewalk installed. Sidewalks along
the new subdivision street should extend all the way along Walnut Street, with an easement shown on the
plans. He suggested moving the water line from the north to the south of the site to reduce site disturbance
and asked Mr. Larson to make sure that the proposed utilities do not interfere with the street trees, on Lot
12, for example.
Responding to a question raised at a previous meeting, Mr. Larson said that when the hospital was closed
the old utility connections for the Middlesex County Hospital were plugged so as to be unusable.
Mr. Hornig also asked that utilities be brought onto the site underground, perhaps when the force main is
constructed, so no utility pole is needed at Walnut Street. He noted that when the conditions for the
required special permit for the development are taken up, he will want to hear about the applicant's plan
for managing construction of the force main, construction plans for Walnut Street and any needed
improvements, and more details about the drainage plans.
Ms. Manz also expressed her concerns about the imprecision of various aspects of the plan, including
pedestrian connections to Lot 1, landscaping on the slopes and the intended use of the triangle of land
below the new roadway at Walnut Street. She asked if the portion of the property that is located in
Waltham could be used for recreational activities, but it was noted that the land was very steep and was
probably not suitable for active recreational use. Ms. Manz noted that the overall impervious surface ratio
still seemed to be too high. Mr. Schilt said that the town engineers are requesting more detail also. He
added that the plans should go before the Development Review Team again. Mr. Larson suggested a mid-
term review by the Board, which was agreed to.
Audience Questions and Comments
Questions from the audience had to do with the length of the force main in Walnut Street and what could
be done to reduce the speed and volume of traffic on Walnut Street. Mr. Schilt noted that a traffic study is
not required for a development of this size, though the study done for a previous proposal for the site
could be reviewed. Mr. Chuck Highland, Potter Pond, pointed out that the large development being built
just over the town-line in Waltham renders a traffic study in connection with this subdivision moot.
Mr. Roger Wrubel, director of Habitat, in Belmont, asked if the developer would consider a conservation
easement. He also suggested collecting rainwater for domestic use.
Mr. Harden reiterated that a traffic analysis is required, along with a peer review to be paid for by the
applicant. These should be supplied before the midterm review.
On a motion duly made and seconded, it was voted 3-0, to approve the preliminary plan and to authorize
the applicant to prepare a definitive plan, conditioned on a midterm review by the Board. Mr. Schilt told
the Board that the Traffic Mitigation Group (TMG), newly appointed by the Selectmen, would have its
Minutes for the Meeting of February 2, 2006 3
first meeting later this week. Its charge is to look at traffic management holistically and with a long-term
view. It will also oversee TDM funds. Mr. Hornig stated that Walnut Street will face long-term impacts
given the amount of development in the area, and that the TMG should review the plans for Lexington
Hills.
Ms. Diane Terry, 25 Walnut Street, asked who considers the impact of additional development and traffic
on the residents of Walnut Street. Neighbors love it the way it was and hate to see it change. Mr. Steven
Heinrich, Potter Pond, likened Walnut Street to a roller coaster track and stated that potential dangers
need to be addressed in any event. He regretted that an initiative begun by the former Assistant Town
Engineer to come to agreement with the City of Waltham about restricting trucks from Walnut Street
seems to have come to naught.
************************ ARTICLES FOR 2006 TOWN MEETING ************************
Inclusionary Housing Zoning By-law Amendment: Mr. Schilt pointed out revisions that were made to the
draft language of the inclusionary zoning by-law amendment. The Board agreed that separating the terms
'inclusionary unit' and 'inclusionary credit' helps to clarify the proposed amendment's concepts.
The need of older residents for dwellings with less than three bedrooms was discussed. The Board
acknowledged the need to give developers options and guidelines. Staff was asked to write up potential
options to be discussed at a meeting held just for reviewing the by-law amendment, as the Board's regular
night meetings last too long to leave time and energy for discussing the zoning amendments.
Mr. Harden said he would work on the language of the amendment presentation.
****************** PLANNING BOARD ORGANIZATION, SCHEDULE *******************
Community Preservation Act - Designate Planning Board Representative: Mr. Schilt noted that the CPA
Committee wants a Planning Board representative on the committee. On a motion duly made and
seconded, it was voted to appoint Ms. Manz as the Board's representative to the CPA Committee.
On a motion duly made and seconded, it was voted to adjourn the meeting at 10:45 p.m.
Charles Hornig, Acting Clerk
