Seney NOI Addendum 3 Revised 11-7-2019 James A. Gracia, PE
99 Glendale Street, Easthampton, MA 01027
November 6, 2019
Revisions to Plan Set:
NOI filed on behalf of Timothy J. Seney for 1087 Westhampton Road
DEP File #247-0735
In regard to the above mentioned NOI, it was decided to re-visit the wetland boundary
delineation to get a second opinion on the delineation. The services of Emily Stockman,
who had previously done a delineation on this property in 2015, were enlisted to review
the most recent delineation performed by Ryan Nelson, from R. Levesque Associates, in
May 2019. Ms. Stockman and Mr. Nelson visited the site together on October 7, 2019 to
review Mr. Nelson’s wetland boundary. Upon visiting the site, it was observed that a
great deal of upland vegetation had grown in areas previously delineated as wetland.
This prompted a more in-depth investigation of the soils in the questionable areas. Based
on the upland vegetation and the non-hydric soils found in the areas previously mapped
as wetland, the boundary was revised. After re-flagging the areas in question, Ms.
Stockman and Mr. Nelson met at the site with the Northampton Conservation
Commission Agent, Sarah LaValley, to review the new boundary. Several new transects
were documented, for both wetland and upland areas in question. The new data sheets
are included in this submission.
With the revised boundary in hand, the driveway alignment, grading, and stormwater
facilities were revised, as shown on this newest set of site plans (revised 11-5-2019). As
a result of the new boundary, the 100’ and 50’ Buffer Zones were changed, which have
allowed us to locate the driveway work so as to avoid any disturbance within 50’ of the
wetland boundary. It has also reduced the proposed disturbance within the 100’ Buffer
Zone. The new driveway design now proposes to disturb a total of only 11,701 SF within
the 100’ Buffer Zone, as opposed to the original proposal which indicated 34,136 SF of
Buffer Zone disturbance. In regard to the total amount of Buffer Zone area within the
subject parcel, it was calculated that the entire parcel contains approximately 257,700 SF
of Buffer Zone area. The proposed 11,701 SF of disturbance equates to 4.5% of the total
Buffer Zone area within the parcel.
The revised driveway design (alignment and profile) is essentially the same as the
original design, with slight modifications to the alignment and profile. The topography
and wetland areas preclude building a house closer to Westhampton Road, therefore, the
driveway must extend to the rear of the parcel to the most feasible building location on
the parcel. The future building site shall be located outside of the Buffer Zone.
This Notice of Intent submission is for the purpose of constructing a driveway to the
future house location. Construction of a house is not part of this submission.
