Re: Proposed Enterprise Bank, 247 Chickering Road (Route 125) " No. 38101 ZZ.
North Andover,Massachusetts
Dated: September 23,2019 S
The undersigned, Robert J. Michaud, P.E. of MDM Transportation onsultants, Inc.,
understands that Enterprise Bank is pursuing construction of a new bank branch on land located at
247 Chickering Road in North Andover, MA (the "Project"), This Engineers Certificate is issued
to outline requirements and anticipated timelines for Non-Vehicular and Category I Vehicular
Access Permits from MassDOT.
The entire Project consists of demolition of the existing commercial building on the subject
property and construction of a new 3,250 sf Enterprise Bank branch with dual drive-through lanes
and approximately 21 surface parking spaces. The subject property borders Chickering Road
(Route 125), a State Highway under the jurisdiction of the Massachusetts Department of
Transportation(MassDOT). Access/egress to the Site is proposed to remain via two existing curb
cuts along Chickering Road; the southern driveway will remain an enter-only driveway and the
northern driveway will remain an exit-only driveway. These driveways will be modified for
conformance with current MassDOT commercial driveways standards and for consistency with
planned roadway improvements by MassDOT along the Chickering Road corridor.
The undersigned hereby states as follows,based on its professional and personal
knowledge and belief:
1. The Project will require Access Permits under M.G.L. Ch. 81, Section .21, as
amended, MassDOT regulations. Specifically, these include a Category 1
Vehicular Access Permit for proposed modification to existing driveways serving
the subject property; a Non-Vehicular Access Permit for the purpose of
constructing a water service connection and a sewer service connection to the
subject property within the State Highway Layout; and a Drainage Access Permit
for purpose of constructing a drainage connection within the State Highway Layout
to MassDOT's proposed drainage system.

Phone(508)303-0370•Fax(508)303-0371 -www.mdmtrans.com
2. A Category I Vehicular Access Permit will be filed with MassDOT on behalf of
Enterprise Bank within the next 15 business days. Under this Category I Vehicle
Access Permit application, physical changes to the driveway intersections with
Chickering Road are proposed that are substantially consistent with the Approved
Site Plans for the subject property and that are consistent with MassDOT's
Chickering Road improvement project. MassDOT is fully informed of the Project
as discussed in meetings held at District 4 office on March 25, 2019 and at a pre-
construction meeting held at District 4 for the Chickering Road improvement
project on September 11, 2019. The Category I Vehicular Access Permit should
issue in the normal course, which is anticipated to occur within approximately 90
days of initial application.
3. MDM Transportation Consultants,Inc.has conducted a pre-filing consultation with
MassDOT District 4 staff on March 25, 2019 and September 11, 2019 in
preparation for a Category I Vehicular Access Permit filing. During this
consultation, a detailed discussion of Permit requirements relative to the Category
I Vehicular Access Permit ensued including compliance with MassDOT's Standard
Operating Procedure (S.O.P.)No. HMD-02-02-2-000"Connection or Discharge to
any MassDOT Drainage System". Provisions under this S.O.P. cite the need for a
Non-Vehicular Access Permit for purposes of connecting the Site to the MassDOT
drainage system, and which seines as a prerequisite to issuance of a Category I
Vehicular Access Permit. MassDOT S.O.P No. HMD-02-02-2-000 specifically
states "As defined in 720 CMR 13.00 and MassDOT's S.O.P. No. HMD-60-02-3-
000, any connection to or discharge to any MassDOT drainage system (in cases
where it can be shown that no practical alternative exists), requires the issuance of
a Non-vehicular Access Permit." Upon review of the Site Plans and associated
drainage mitigation summary prepared by GPI and dated August 16, 2019
(submitted herewith)and as discussed with MassDOT District 4 staff on September
11, 2019 we anticipate that sufficient evidence is provided in the Application to
demonstrate that"no practical alternative exists"for this drainage connection. The
GPI drainage mitigation summary indicates that storm water features for the Site
result in a reduction in peak runoff rates relative to existing levels,increases on-site
recharge rates from roof drains,improves on-site water quality, and is subject to an
operation and management plan.
4. MDM will concurrently file the requisite Non-Vehicular Access Permit
Applications for the proposed drainage connection to MassDOT's Chickering Road
system and proposed water/sewer connections and anticipates the Non-Vehicular
and Category I Vehicular Access Permit will issue in the normal course, which is
anticipated to occur within approximately 90 days of initial application.
S. I know of no reason why the above described Category I Vehicular Access Permit
would not be issued. I also know of no reason why the above described Non-
Vehicular Access Permit would not be issued.

Re: Drainage Mitigation Summary
Proposed Enterprise Bank
247 Chlckering Road
North Andover, MA
Dear Bob:
On behalf of our client, Enterprise Bank, the following information is provided in response to the request by
MassDOT District 4 regarding the stormwater mitigation proposed for the above referenced project.
The existing parcel of land is 24,952-sf in size, fully developed with paved parking areas and currently
occupied by the BulgerAnlmal Hospital. The site is bounded by Chickering Road(Route 125)to the west,the
99's restaurant and parking lot to the north and east and wooded land and wetlands to the south. No stormwater
controls currently exist onsite, all runoff drains as sheet and shallow concentrated flow to the Chlckering Road
closed drainage system.
Enterprise Bank Is proposing to construct a 3,260-sf single story bank building with drive-up services and a
parking lot with 20 spaces. The redevelopment of this site will result In a decrease in Impervious cover,from
87.3% existing to 68.6% proposed. In accordance with both Town and State requirements, an on-site
stormwater management system was designed to treat the stormwater runoff and mitigate the post-development
peak rate and volume of runoff.
A standard closed drainage system consisting of deep sump, hooded catch basins connecting to a First
Defense hydrodynamic separator is proposed within the northern portion of the site to collect runoff from the
parking lot and drive-up lanes.This system is designed to capture and pretreat runoff prior to discharge Into the
Chickering Road closed drainage system. Along the southern portion of the site,two Filterra tree box filters are
proposed to collect and treat the runoff from the remaining parking lot areas. In front of the building, an
underground roof infiltration system consisting of arch chambers will provide groundwater recharge of the
rooftop runoff.
Prior to the design of the onsite stormwater system, test pits were performed to determine the depth to
seasonal high water and soil conditions, Based on the results of the test pits along with the proposed site grades
and available space around the site,the only feasible location for groundwater recharge is in front of the building.
Where the existing grade rises towards the back of the property,we cannot meet the groundwater separation
required for stormwater infiltration practices.
A Stormwater Management Report was prepared (copy attached) and includes a pre-and post-development
drainage analysis. The results of that analysis indicate that for the 2, 10 and 100-year storms there will be a
decrease in the peak rate of runoff going to the Chickering Road closed drainage system.

In addition, by reducing the on-site Impervious cover and providing groundwater recharge of the roof runoff,
there will also be a reduction in the volume of runoff leaving the site.

As requested by MassDOT, altemative drainage discharge/tie-in locations were investigated. Site grades
make discharge to the wooded area to the south of the site infeasible, plus,this is within close proximity to a
wetland. There is a closed drainage system within the 99 Restaurant parking lot however, a connection to that
system was deemed infeasible. Representatives of the 99 expressed concerns to Enterprise Bank over the age
of their system(approximately 25-yrs old),belief that there is no available additional capacity to handle additional
runoff from the Enterprise Bank development, and the fact that the 99 parking lot was just paved for the first
time In 25 years.
In summary, we believe that based on the Inability to connect to the 99 Restaurant's drainage system, the
limited capacity to provide onsite stormwater recharge,the significant improvement to the onsite drainage design
through the BMP's that have been implemented, and the reduction in peak rate and volume of runoff to the
Chickering Road drainage system, that all steps that could be taken, have been taken to mitigate the impact
that the stormwater runoff will have on the MassDOT drainage system.

Greenman-Pedersen,Inc.
