HISTORY AND BACKGROUND On October 9, 2024 the applicant requested a waiver of the Watershed Protection District Special Permit, in accordance with the North Andover Zoning Bylaw Article 4 Section 195-4.24, Waiver of Special Permit, so as to allow construction of a construction of a 14=4' x 16.5' kitchen addition and 14.4' x 16.5' screened porch in the Non-Discharge Zone of the Watershed Protection District. Bordering vegetated wetlands are located approximately 180' away from the proposed land disturbance. The additions and landing foundation will consist of seven concrete footings. The project does not require any change to topography, vegetation removal, expand the existing footprint of the structure, and the structure is on town sewer. FINDING OF FACT The Planning Board has made its decision based on the following findings: • The scope consists of installation of seven concrete footings, • No vegetation removal or regrading is required. • A waiver of the Watershed Protection District special permit is requested, and although there is an impervious structure proposed there will be very limited ground disturbance. • The September 23 2024, revised to October 7, 2024, site plan was created by Hayes Engineering, Inc. and the stormwater management design captures '/z inches of rainfall in 12 hours over the entire roof area with a safety factor of 65% size. • The existing and proposed roof drains are proposed to connect to 4 Cultec C-100 subsurface infiltration chambers. • Town Engineer, Sohn Borgesi,peer reviewed the stormwater management design and deemed it to be sufficient, CONDITIONS • A 12" diameter mulch sock, staked at 4' intervals, will be installed at the limit of work prior to building permit issuance. • As required per§195-4.24 Waiver of special permit on the Zoning Bylaw,the applicant i i must schedule and agree in writing for the Town Planner to perform a minimum of two inspections during the construction process to ensure proper erosion control is established during construction. • The Applicant shall incorporate the following conditions as a deed restriction and a copy of the recorded deed restriction shall be submitted to the Town Planner and included in the file. o Fertilizers are limited to those which are either organic or slow-release nitrogen and phosphorous free. o The use of coal tar-based pavement sealants is prohibited. • This decision must be filed with the North Essex Registry of Deeds and a copy of the recording submitted to the Town Planner.The following information is included as part of this decision: Plan titled: Plan of Land in North Andover, Mass.

The CULTEC chambers create arch-shaped volds within the washed stone to provide stormwater detention, retention, infiltration, and reclamation. Filter fabric is placed between the native soil and stone interface to prevent the Intrusion of fines Into the system. In order to minimize the amount of sediment which may enter the CULTEC system, a sediment collection device (stormwater pretreat- ment device) is recommended upstream from the CULTEC chamber system. Examples of pretreatment devices include, but are not limited to, an appropriately sized catch basin with sump, pretreatment catchment device, all grit separator, or baffled distribution box. Manufactured pretreatment devices may also be used in accordance with CULTEC chambers. Installation, operation, and maintenance of these devices shall be in accordance with manufacturer's recommendations. Almost all of the sediment entering the stormwater management system will be collected within the pretreatment device. Best Management Practices allow for the maintenance of the preliminary collection systems prior to feeding the CULTEC chambers. The pretreatment structures shall be inspected for any debris that will restrict Inlet flow rates. Outfall structures, if any, such as outlet control must also be Inspected for any obstructions that would restrict outlet flow rates. OSHA Guidelines must be followed when Inspecting or cleaning any structure. Operation and Maintenance Requirements I. Operation CULTEC stormwater management systems shall be operated to receive only stormwater run-off In accordance with applicable local regulations. CULTEC subsurface stormwater management chambers operate at peak performance when Installed In series with pretreatment. Pretreatment of suspended solids is superior to treatment of solids once they have been Introduced into the system. The use of pretreatment is adequate as long as the structure Is maintained and the site remains stable with finished Impervious surfaces such as parking lots,walkways, and pervious areas are properly maintained. If there is to be an unstable condition, such as Improvements to buildings or parking areas, all proper slit control measures shall be Implemented according to local regulations. II. Inspection and Maintenance Options A. The CULTEC system may be equipped with an Inspection port located on the Inlet row. The inspection port Is a circular cast box placed in a rectangular concrete collar. When the lid Is removed, a 6-Inch (150 mm) pipe with a screw-in plug will be exposed. Remove the plug. This will provide access to the CULTEC Chamber row below. From the surface,through this access, the sediment may be measured at this location. A stadia rod may be used to measure the depth of sediment if any In this row. If the depth of sediment Is In excess of 3 Inches (76 mm),, then this row should be cleaned with high pressure water through a culvert cleaning nozzle. This would be carried out through an upstream manhole or through the CULTEC Storm Filter Unit (or other pre- treatment device), CCTV inspection of this row can be deployed through this access port to deter mine if any sediment has accumulated In the Inlet row. B. If the CULTEC bed is not equipped with an inspection port, then access to the inlet row will be through an upstream manhole or the CULTEC StormFliter. 1. Manhole Access This Inspection should only be carried out by persons trained In confined space entry and sewer Inspection services. After the manhole cover has been removed a gas detector must be lowered Into the manhole to ensure that there are not high concentrations of toxic gases present. The inspector should be lowered into the manhole with the proper safety equipment as per OSHA requirements. The inspector may be able to observe sediment from this location. If this Is not possible, the Inspector will need to deploy a CCTV robot to permit viewing of the sediment.

Storm Fliter Access Remove the manhole cover to allow access to the unit. Typically a 30-inch (750 mm) pipe Is i used as a riser from the StormFilter to the surface. As in the case with manhole access, this access point requires a technician trained in confined space entry with proper gas detection equipment. This individual must be equipped with the proper safety equipment for entry Into the StormFliter. The technician will be lowered onto the StormFliter unit.The hatch on the unit must be removed. inside the unit are two filters which may be removed according to StormFllter maintenance guidelines. Once these filters are removed the Inspector can enter the StormFliter unit to launch the CCTV camera robot. C. The Inlet row of the CULTEC system is placed on a polyethylene liner to prevent scouring of the washed-stone beneath this row. This also facilitates the flushing of this row with high pressure water through a culvert cleaning nozzle. The nozzle Is deployed through a manhole or the StormFliter and extended to the end of the row.The water is turned on and the Inlet row Is back-flushed into the manhole or StormFliter. This water Is to be removed from the manhole or StormFliter using a vacuum truck. ITT. Maintenance Guidelines The following guidelines shall be adhered to for the operation and maintenance of the CULTEC stormwater management system: A. The owner shall keep a maintenance log which shall Include details of any events which would have an effect on the system's operational capacity. B. The operation and maintenance procedure shall be reviewed periodically and changed to meet site conditions. C. Maintenance of the stormwater management system shall be performed by qualified workers and shall follow applicable occupational health and safety requirements. D. Debris removed from the stormwater management system shall be disposed of In accordance with applicable laws and regulations. IV. Suggested Maintenance Schedules A. Minor Maintenance The following suggested schedule shall be followed for routine maintenance during the regular operation of the stormwater system: Monthly In first year Check Inlets and outlets for clogging and remove any debris, as required. Spring and Fall Check Inlets and outlets for clogging and remove any debris, as required.
