Dear Ms. Griffin:
We have received a copy of Vanasse Hangers Brustlin, Inc.'s May 17, 2001 review letter
regarding the above referenced project,, and we offer the following response. To facilitate
the review of this 'Information,, we have reproduced each of VBB"s comments in Italics,
and our response to each comment immediately follows.

Section 5.2.6 requires that the Board of Health or their designated agent witness
the test pits. We have attempted since late March to schedule the test dates with
the Health Department, and the appropriate fee for the testing was paid in early
April. After numerous calls to the Health Department in an attempt to schedule
the testing,, we were recently told by the Health Agent that since the Board of
Health was currently without an engineering consultant they would not be able to
witness the testing. In order that we would have the test pit results,prior to the
Planning Board's first scheduled hearing on the project.., we performed the tests on
the morning ot May 22, 2001 without any town representatives present. The
plans have been revised to Include the test locations and results.

The proposed subdivision consists of the creation of 6 lots,from 2 existing lots. 4

new singie-mmily house lots Will be created. The rem * * I
adjusted lot lines around the existing apartment building at#429 Waverley Road

on the environment and community will be limited to the 'impacts of the

The proposed roadway intersection will occur along a long straight section of
Waver ley Road. The sight distance at the location of the proposed intersection 'is
approximately 500'to the north and 10001"to the south. These distances exceed a I
appropriate standards,for an intersection of this,type.

As is indicated on the Site Grading plan, all of the proposed driveways will slope
from the edge of the roadway right-of-way towards,the edge of'the roadway
pavement. All of the roadway-runoff will be carried along the gutter line to the
catch basins. The plan does not indicate any locations where roadway runoff will
flow down a driveway onto priviate pro petty. The plans have been revised to
inctuce a typical driveway detail.

Section 6'.14.7 states: "Any alteration of land on the site shall be such that changes
in existing patterns of drainage shall not affect properties outside the subdivision
by 'increasing the amount or rate of peak flow as designated by the Wetlands
Protection Act." As indicated in the Storm eater Management Report, there will
be no increases in peak flow rates to properties outside of the subdivision. The
isolated freshwater wetland is located entirely within the subdivision boundaries
and is not Jurisdictional under the Wetlands Protection Act. A Notice,of Intent
will be filed with the Conservation Commission under the Town's Wetlands,
Protection Bylaw to address any wetlands 'issues.

The proposed drainage system consists of four catch basins along a 370-foot long
roadway. All of the catch basins connect to the proposed detention/infiltration
area. A Drainage System Capacity Analysis is included in the Stormwater
Management Report to verify that the drainage system is adequately sized to
convey the runoff to the detention/infiltration area. Given the fact that the two
catch basins located at,the end of the cul-de-sac will he in the low points of the
roadway right-of-way, all of the runoff from the roadway Will be directed into the
detention/infiltration even if some bypass f'the first two catch basins were,to
occur. Gutter flow calculations are not required to verify that the drainage system
will collect all of the runoff from the roadway and direct it to the
detention infiltration area.

The detention/infiltration area has been designed such that it should not hold
standing water for any extended time,, so,no tence should be required. If the
detention/infiltration area is, maintained according to the procedures listed in the
Stormwater Management Operation/Maintenance Plan, stormwater will infiltrate
into the ground within a few hours of'the end of the rainfall.

The sideslope grading is properly labeled on the detail. The slope is not labeled
as 113-.1 111; it is,represented graphically by a horizontal component (3 MIN.), and a
vertical component(1). Changing "A/111N" to "MAX"' would result 'in a slope of 2

to,be non-jun'sdictional under the Wetlands,Protection Act,, but Jurisdictional

necessary, the street lights will be added to the,plan at whatever locations the
Board specifies.

We have also revised the plans to address Building Corarm'ssioner Robert
Nicetta's May 21, 2001 memo regarding the location and number of the parking spaces at
the two existing buildings. The approximate locations, of the existing, spaces have been
added to Sheet 3 of the plans. It should be noted that there are no proposed changes to
the existing apartment building that would require additional or upgraded parking
facilities (as per, Section 8.1.1 of the Zoning Bylaw).
