RE: WETLAND RESOURCE AREAS @ PROPOSED STOP &SH0PAs you riay be aware,"the applicant for the above referenced project has filed a Rea uest for Determination
of ApplicaHity with the Nam Andover Conserva#icn Commission (NACC), S pecificafly, they are seeking
confirmation of'all wettand boundaries jurisdictional under the Massachusetts Weiland Protection Act and
North Andover Wet and ByLaw.' On-site jurisdictional weti and s include;
1. Bordering land Subject to Flooding (i.e. "t9oodplain');
2. Riverfro r i Area;
3. Bordering Vegetated Wegand,
The Floodplain: Bordering Land Subject to Flooding-
A floodpIain efevaboh of 236.74' NCVD Eras been proposed by the applicant and subsequently approved by
the NACC at a pudicheadrq on May 7r 1997,
R€ver€r'ont Area:
At the time of inspection, Mosgufto Brook was observed to be ;low1ng by this Deparnent and the
applicant's represerkta#ive, Mr. Curt Young of WPI, Inc; thus It may be inferred that the strum is perennial
atria subject to j uris dfclon under the Riverfront Act. The burden is on the applic ant to prove otherwise and
as a means of facilitating this review f have requested addition a! supporfing data from WPf per tie NA C
'Riverft-ont Area Guidelines', As a result. no deteri•Nnatior[was made under this N41g, MosQuito Brook is
almost 200' away arrd should the Riverfron.Act apply, this Dep ar ment does not anffc pate Significant
issues.
8Grde inn Vegetated Wetland (BVW) & Bank:
'r he BVW and Bank delineatiork as depicted on the p Ian s cdrreni y before the P Ian ri[n9 Board is acwuuate.
o modifacalons yore made to the flagged line by this Departrnent_
Stormwater Management:
It is assumed that the applicant will file a Notice of Intent with the NACC for future �Nork on the subject
parcel. While )l do not foresee dmajor' probl&ns specific to wetland setbacks 11 do anticipate a detailed and
carnpficited review of the proposed Stovmwat6,, management system. TF2 app�fcantwill be expected to
comply with DEFs 'S tofmwatet Manaiaemeni Policy" which attempt5 to address both water qualii`y
(pollutants) and wafer quantity{flood control} problems by esta Nis hing the IzaieI of required controls
throuah the use of 8MP'& The applicant has repeatedly stated to this Depawent and the NAC C that his
representative is designing the drainage system according to 0EP policy- It this is accurate and the vroik is
correct, than a iengtby review process with Lhe NACC Is not like;y,
