RE: Stormwater Review
100 Dale Street WSP
Dear Ms. Tymon and Board Members:
Per your request, I have conducted a technical review of the April 4, 2013 Watershed
Special Permit Application packet submitted by Christiansen & Sergi, Inc. for the above-
referenced project. Included in the materials I received and reviewed were the following:
§ Watershed Special Permit Application, 100 Dale St, Lots 1 and 2, Messina
Development Corp., prepared by Christiansen & Sergi, Inc. and dated April 4,
2013.
§ Site Development Plan for Watershed Special Permit (1 sheet), 100 Dale Street,
Applicant: Messina Development, prepared by Christiansen & Sergi, Inc. and
dated April 4, 2013.
My primary focus in this technical review is on the overall stormwater management
approach and design concepts used in the project, as well as its compliance with the
Town of North Andover’s zoning requirements for Watershed Protection Districts, the
Massachusetts Department of Environmental Protection (DEP) Stormwater Management
Standards and Regulations, and the North Andover Wetlands Bylaw. It is my
understanding that either a Notice of Intent (NOI) application or an Abbreviated Notice
of Resource Area Delineation (ANRAD) has been or will be filed for this project with the
Conservation Commission. My review is aimed at assisting both the Planning Board and
the Conservation Commission in their respective reviews of the project.
The proposed project entails the demolition of an existing single family home and
construction of two new homes and driveways on two recently subdivided lots at 100
Dale Street. Both lots are located wholly within North Andover’s Watershed Protection
District, and portions of both lots are within the buffer zone of regulated wetlands.My
comments on the proposed plan are outlined below:
1. Based on the plan, most of the proposed development on Lot 1 and all of the
proposed development on Lot 2 is located in the Non-Discharge Buffer Zone. A
portion of the proposed driveway on Lot 1 is shown as being within the Non-
100 Dale St, Stormwater Review 2

Disturbance Zone. The boundaries of these buffer zones are based on the
horizontal setback from the edge of all wetland resource areas as defined by the
Wetlands Protection Act and the North Andover Wetland Bylaw. The plan should
show all of the wetland areas within 400 feet of the property, and the boundaries
should be confirmed by the Conservation Commission.
2. The proposed plan calls for regrading, vegetation removal and driveway
construction within the Non-Disturbance Zone, all of which require a Special
Permit under the Watershed Protection Regulations. In accordance with the
regulations, the Applicant should provide proof that there is no reasonable
location for this activity outside of the Non-Disturbance Zone, e.g. by moving the
driveway to the other side of the house.
3. The Plan should also show the Zone A for the Lake Cochichewick public water
supply, defined by the Massachusetts Drinking Water Regulations (310 CMR
22.02) as including the land area within a 200 foot lateral distance from the upper
boundary of the bank of a tributary or associated surface water body.
4. The plan calls for infiltration of runoff through roof infiltrators and infiltration
trenches adjacent to the driveways, however no soils data have been provided to
document the suitability of the site for onsite infiltration.
5. Infiltration structures, including the driveway trenches, should have a minimum
10-ft setback from an abutting property.
6. I recommend that the creation of new lawn area be limited to that which is
absolutely necessary, and that any new landscape area be constructed in such a
manner as to minimize the maintenance that is required, e.g. the soil should be
well aerated, it should have a minimum of 6-inches of topsoil and, where possible,
native vegetation should be planted to minimize the need for fertilizer and
watering. The Board may want to request a planting or landscape plan for the lots.
As with similar projects permitted within the Watershed Protection District, both
the limits of approved clearing and the restriction on lawn care products should be
permanently recorded on the deed to the property.
7. Ongoing maintenance of proposed stormwater management structures should be
addressed.
8. A Construction Sequence aimed at minimizing the total area and duration of soil
disturbance should be provided.
9. The stone used for the proposed construction entrance should be a minimum of 2-
in diameter.
I appreciate the opportunity to assist the North Andover Planning Board and
Conservation Commission with the review of this project, and hope that this information
