RE: Old Center Lane Development
Johnson Street; North Andover, MA
Dear Mr. Osgood:
ENVIRONMENTAL IMPACT STATEMENT
This document evaluates the potential impact of the proposed residential development at
Old Center Lane on the environment associated with the established Watershed Protection
District in the town of North Andover. In particular, we will report on the potential this project
has for significant degradation on the quality of Lake Cochichewick waters.
The preparation of this report comes from our office performing a thorough review of
"Watershed Special Permit Plan" of land on Johnson Street prepared by New England Eng-
ineering Services, Inc.;North Andover, MA and dated 12/20/96 (w/revisions 3/3/97).
Potential Standard) DeVydations
(1) Site grading within 100' buffer zone;
(2) House construction within 100' buffer zone;
(3) Onsite sewage disposal systems;
(4) Stormwater runoff from impervious surfaces;
(5) Lawn care fertilizer runoffs.
Proposed(Specific) Solutions
(1) Prior to any site work (logging, excavating, filling, regrading, etc.) erosion control
measures (combination silt fence and staked hay bales) should be installed, inspected, and
maintained until such time as soil is stabilized;

(2) Do not allow housing (permanent structure) construction to take place within 100' of
delineated wetland boundary;
(3) Housing wastewater and sewage should not be deposited into the subsoil; but rather,
pumped or piped out of the Watershed Protection District;
(4) Impervious surface water runoff should not be discharged directly into the delineated
wetlands;but rather, the runoff should be treated (filtered) by overland sheet flow to
allow a natural percolation into subsoil;
(5) Organic fertilizers should be required for lawn treatments in this development.
If the above-mentioned solutions are applied and conditionally adhered to, the high
concentrations of nitrogen, phosphorous and other dissolved inorganic chemicals will be greatly
reduced or eliminated all together in the runoff water and ground water. It is our opinion, this
single-family residential development will not significantly degrade the quality of water in or
entering Lake Cochichewick.
