Rowen, Chairman Kathleen Bradley Colwell, Town Planner Planning Board North Andover, MA 01845 RE„ Allen Trust - Robert A. Brawn Pre►perty - Map 62, Lot 23 Bradford Street Dear Mr. Rowen, The following addresses the siting of the house can the property and the quality and quantity of water entering Lake Cochichewick. First T will address the siting of the house on the lot. The lot was created prior to October 24, 1994 and therefore is subject to a 100 font Non Disturbance Zone and a 325 foot Non-Discharge Zone. Although the lot is 5.67 acres, the configuration of the wetlands in two fingers create: a situation where there is no land, on the lot outside the Non-- Discharge Zone of 325 feet. We feel we have sited the house to present the minimum impact on the lot and not force it right up to the existing neighbors. The house is completely outside the 100 foot buffer zone except for a portion of the roof runoff underground leaching facility in the 100 font buffer zone.. The limit of work and maneuver area has been established by locating the hay bale/silt fence 60 feet from the BVW. In addition a past and rail fence will be installed on the house side of this barrier prior to its removal. This fence will act as the limit of mowing line. Since the entire project is 'within the Non-Discharge Zone we have proposed x. 1000 square foot leach bed for the roof drains and a total of approximately 520 feet of 12"x121' (1560 sq. ft. ) leaching trench along both sides of the driveway. The final grade of the paved driveway will pitch slightly tca each side and will shed the surface runoff to these trenches . The leaching bed provides a factor- of safety of 2 for the 100 year storm and the leach trench provides a factor of safety of 3. The net result of these will be a reduction in the quantity of runoff from the site since all roof and driveway runoff will :infiltrate into the parent, soil and therefore also not change the quality of the runoff . A covenant will be placed in the deed concerning the types of fertilizers which can be used on the site. Rowen , Pct 2 01 9/2/98 The hay bales and silt fence are shown on the plans. Because of the shallowness of the groundwater (less than 3 feet) some fill will be required over the root drain leach field. All disturbed area will be loamed and seeded as soon as possible. Any soil requiring stockpiling will be stockpiled to the south of the house and driveway. Should you have any questions please call us. Very truly yours; O'F ME$ALFRED O'DAY ames A.

In this letter and the attached plans you have indicated a new layout of in-ground infiltration locations. Incorporated within the original Decision of Approval is contained a clause indicating that modifications to the Special Permit may be reviewed by the Planner. If the Planner finds modifications to be substantial, the applicant must return to the Planning Board. Based upon the discussion at the original hearing, the letter and plan that you have provided and my discussions with representatives of the Conservation Commission, I find that no substantial change is presented. I make this'finding in accordance with the following: • The existing Permit layout is not possible due to the final pitch of the site—water cannot flow uphill to the single leach bed area without some form of pump, which will only increase the risk of failure. • The Applicant proposes three distinct locations to accommodate different portions of the runoff thus minimizing the impact of any failure. • Changing from one large area to three areas reduces the point impact of any runoff thus in essence increasing the natural functionality of the site and minimizing chance of system failure from an intense localized use presented by the original single leach area. • One of the proposed locations lies outside of the buffer thus reducing the actual impact to the buffer area and the protected resource. • The two remaining systems, although in the buffer, represent a substantial decrease in actual impact to the protected buffer.

As a result of the above, I find that not only are the proposed changes not substantial, but that they in fact enhance the intent of the bylaw and the planning board's approval and concerns related thereto. If you have any questions regarding my determination, please feel free to contact me at your convenience.

SCOTT Director August 5, 1998 Mr. Robert A. Brown Allen Trust 242 Andover Street Andover, MA 01810 Re: Bradford Street—Watershed Special Permit Dear Mr. Brown, I have reviewed your application for a watershed special permit and find the following items missing as required by Section 4.136 (4) of the Zoning Bylaw: 1) Special Permit Application: Application does not refer to the appropriate section of the bylaw. You should be requesting a special permit under section 4.136 (3)(b) and(c) for work within the non-disturbance zone related to the creation of a yard and drainage for the construction of a single family home. The application should reference the fact that this lot was created prior to October 24, 1994. 2) Plan: a) A Registered Professional Engineer, not a Professional Land Surveyor, must prepare the plan. b) The Non-Disturbance and Non-Discharge Zones must be shown on the plan and labeled as such. The current plan shows the 75' and 150' buffer zones which do not apply to this lot and are therefore confusing. The plan must also show the proposed limit of vegetation clearing (limit of work). c) The plan must contain existing and proposed topography at 2' intervals. This is necessary in order for the Board to determine the extent of the proposed disturbance and to analyze the drainage patterns on the site. BOARD OF APPEALS 688-9541 BUILDING 688-9545 CONSERVATION 688-9530 HEALTH 688-9540 PLANNING 688-9535 d) The plan must show proposed erosion control methods and locations. e) Test pit locations must be shown on the plan.

I recommend that you withdraw your current application and re-file when all of the required information has been provided. I would be happy to meet with you to review the submittal requirements.

Infiltration trench inverts, relative ground water table elevations and a correlation between plans and test pit lags should be indicated on the plans. It is unclear that the recommended two feet minimum separation between,groundwater and the base of the infiltration system is provided. Percolation calculations for the drainage infiltration trenches incorrectly assume a direct conversion between percolation rates and permeability. This may be acceptable based on the factor of safety(2)provided. In addition, the foundation as designed appears to be located in the groundwater table. Typically, structures in this district are constructed above the e g oundwater table to avoid altercation of groundwater conditions. 101 Accord Park Drive 781-982-5400 Norwell, MA 02061-1695 Fax:781-962°5490 Section 4,136)3.)a.)i.)2.),A,sewer easement is not indicated on the plan.
