The Board finds that owing to circumstances relating to soil conditions, shape, or topography of the land or structures and especially affecting such land or structures but not affecting generally the zoning district in general, a literal enforcement of the provisions of the Bylaws will involve substantial hardship, financial or otherwise, to Applicant, and that desirable relief may be granted without substantial detriment to the public good and without nullifying or substantially derogating from the intent or purpose of the Bylaws. Therefore, the Board finds that Applicants have satisfied the provisions to allow the requested variance relief for construction of a new permanent structure only after a variance has been granted by the Zoning Board of Appeals in the R-1 Zoning District and Watershed Protection District for the purpose of installing an in-ground swimming pool within the 150' non-disturbance zone within the Watershed Protection District pursuant to the Town of North Andover Zoning Bylaws Section 195-4.19.C(2)(c) in accordance with the plans, other materials, and testimony at the public hearing.

(HW) is pleased to provide the North Andover Planning Board with this letter report summarizing our second review of the Watershed Special Permit Application and Zoning Variance Application for the proposed swimming pool project at 115 Winter Street in North Andover, MA. The plans were prepared by Williams&Sparages on behalf of Adrienne and Adam Ramos (Applicant). The project proposes the installation of an 18 foot by 38 foot in-ground swimming pool, with a concrete patio, paver walkway and chain link fence. The stormwater management for the proposed improvements includes a 24-inch wide, 2-foot-deep infiltration trench along two sides of the patio to allow stormwater from the patio to infiltrate into the ground during a storm event. In addition, the swimming pool will be equipped with a non-backwash filtration system. The proposed pool is a 684 square foot(sf) permanent structure. The footprint of the existing house is approximately 3,200 sf. A total of approximately 1,600 sf of additional impervious area Including the pool, patio and walkway is proposed within the 4.13-acre parcel. The residential lot is located within the Watershed Protection District and was created after October 24, 1994. The project is proposed within a portion of the Non-Discharge Zone from the edge of a wetland resource area located to the south of the existing house. The closest point'of the proposed patio adjacent to the pool is approximately 134 feet from the resource area to the south. The proposed limit of disturbance Is greater than 100 feet from the wetland resource area. In accordance with §195419 B. (2) of the North Andover Zoning Bylaws, any surface or subsurface discharge of stormwater within the Non-Discharge Buffer Zone is only allowed after a special permit has been granted by the North Andover Planning Board. A portion of the project area is also located within the 150-foot Non-Disturbance Zone. In accordance with §195-4.19 C. (2)(c)the proposed project also requires the granting of a variance by the Zoning Board of Appeals. The Applicant has applied for the variance from the ZBA.

A Pentair System 30 Modular Media Filter is proposed (see attached filter description and owner's manual). • The property owner shall engage a water hauling company to pump the water and truck the water offsite anytime the pool needs to be drained. Final disposal of the water by the water hauling company shall be in accordance with all federal and state regulations. • Pool water shall be dechlorinated by not adding chemicals and letting the pool water sit for a wdnimum of 10 days. At that point, the pool water can be pumped into the proposed infiltration trench system during normal dewatering following storm events. • Pool chemicals shall be properly stored according to manufacturers' labels in an enclosed shed or garage to ensure proper containment of any spills or drips. Pool Filtration System • Pool filtration system to be cleaned and maintained in accordance with manufacturer specifications detailed in the attached owner's manual, • Once operating pressure reaches 10 PSI above initial operating pressure, inspect and clean filter element. Filter element should be cleaned with hose and drained into stone infiltration trench, • On a weekly basis, debris should be removed from skimmer basket, The pump should be stopped,release all pressure, and remove trap cover and basket to remove any additional debris, Air filter should be bled each time system is started, Infiltration Trench This Operations &Maintenance Plan has been prepared to comply with the provisions set forth in the Massachusetts Department of Environmental Protection (DEP) Stormwater Management Standards.

Maintenance schedules found below are recommended in Department of Environmental Protection's Massachusetts Stormwater Handbook and as recommended in the manufacturer's specifications. The stormwater management system owner and the party responsible for maintenance of the stormwater management system shall be the property owner and their designated employees. • Inspect and clean every six months and after every major storm event of 0.5 inches in a 24-hour period. • Remove accumulated sediment,trash, debris,leaves and grass clippings. • Remove tree seedlings before they become fixmly established. • inspect the trench 24 hours or several days after a rain event to look for ponded water. If there is ponded water at the surface of the trench,it is likely that the trench surface is clogged. • To address surface clogging,remove and replace the first layer of stone aggregate and filter fabric. If the water is ponded inside the trench,it may indicate that the bottom of the trench has failed. • To rehabilitate a failed trench, all accumulated sediment must be stripped from the bottom,the bottom of the trench must be scarified and tilled to induce infiltration,and all of the stone aggregate and filter fabric or media must be removed and replaced.
