The proposed site development, shown as Option E, presented at the January 11"' meeting proposes to move the existing house to the north to provide a more equal setback from all wetland resource areas around the structure. Wetland resource areas are proposed to be filled/replicated to create a usable back yard and to provide space to create a buffer between the usable back yard and the wetland resource areas. As previously pointed out the current yard extends to the existing wetland edge. The Commission requested that we re-evaluate the proposed extent of the wetland filling and also show any temporary wetland alterations required to cross the wetland in order to access the site of the wetland replication areas. We have reduced the proposed usable yard which in turn has reduced the proposed wetland filling to 1,520sf; a reduction of 820sf from the previous design. The proposed wetland filing is 360sf less than the proposed wetland filing for Option A, which proposed a driveway across the wetlands to gain access to the upland areas on the easterly side of the lot. Two wetland replication areas totaling 3,080sf are proposed resulting in a 2:1 wetland replication ratio. Temporary wetland impacts in order to gain access to the site of the replication area is 555sf; this area will be 100% restored in place once the replication areas are constructed. The total wetland alteration, including the temporary wetlands altered, is 2,075sf. Please find enclosed a report from Greg Hochmuth, of Hancock Associates, that discusses the proposed wetland replication, temporary wetland alteration and buffer zone enhancement plantings.

Based on the previous design alternatives proposed we believe that Option E, as revised, will not have any adverse effects upon any of the interests protected by the Bylaw. The proposed project will improve the natural capacity of the resource area to protect the interests identified in the Bylaw by creating a greater distance between a structure and the wetland and by creating a buffer between the wetland edge and the usable lawn area which currently does not exist. We look forward to meeting with the Commission at your next regularly scheduled meeting on February 22, 2012 to further discuss this matter. If you have any questions prior to the meeting please do not hesitate to contact me. Sincerely, THE NEVE-MORIN GROUP, INC. 7f9A1\- M°�.. John M.

If you cannot comply with any portion of the North Andover Wetlands Regulations you should file this Waiver Request identifying any areas where your proposed project is not in full compliance. Project: 14 Lorraine Avenue Applicant: Breenmore Realty Trust Applicant's Address: c/o The Neve-Morin Group,Inc. 447 Boston Street Topsfield,MA 01983 Phone: 978-887-8586 I hereby request a Waiver from Section(s)5.1: No Disturbance Zones and 5.2: No Build Zones and 5:3: Vegetated Wetland Alteration of the North Andover Wetlands Regulations. The reason(s)for this Waiver Request are described below: The current usable lawn area on the site is right to the wetland edge; the 25 foot no disturb zone would allow no yard. The proposed proiect will provide a no disturb zone where one currently does not exist. There is no location on the westerly upland portion of the lot to build a structure outside the 50 foot no build zone. The proiect proposes to remove a garage which is 12 feet from the wetland edge, relocate the existing house which is 18 feet to the wetland and provide a minimum setback to the wetlands of 24 feet. The filling of wetlands is proposed to create a usable yard, provide a greater setback from the lot development to the wetland edge and allow us to create a buffer between the lot development and the wetland edge.

More specifically,the work involves the razing of an existing single family dwelling and detached garage followed by the construction of a new single family dwelling in approximately the same footprint. In an effort to provide a suitable yard for the proposed dwelling the applicant is proposing to fill a small portion of the bordering vegetated wetlands behind the structure, approximately 1,520 S.F. As mitigation for the proposed wetland alteration the applicant is proposing to construct a wetland replication area, to the east of the proposed alteration, on the other side of the bordering vegetated wetlands. The proposed replication area is approximately 3,080 S.F. and once constructed will result in a 2:1 replication to alteration ratio. Please fmd attached a wetland replication plan and wetland replication construction methodology as well as buffer zone enhancement plan. Because the wetland replication area is on the other side of the wetland resource area we have also included a temporary access & temporary wetland alteration/restoration construction methodology. We look forward to presenting this information at the continued public hearing on February 22,2012. If you should have any questions regarding this information please do not hesitate to contact our office. Sincerely, HANCOCK ASSOCIATES 4— Gregory J.

Prior to the commencement of construction on site,the bordering vegetated wetland line shall be flagged with surveyor's tape and shall remain in place during construction. 2. Siltation barriers consisting of trenched silt fencing shall be installed between the edge of the proposed replication areas and the edge of the existing wetland prior to the start of excavation. These will remain in place and be maintained until all areas are stabilized. 3. The wetland replication area shall be excavated to the elevations indicated on the design plan. A subgrade of 1 foot below proposed finish grade shall be established so that 12 inches of the specified soil medium can be used. 4. The soil medium to be used in the wetland replication area shall consist of equal volumes of organic and mineral materials. Organic material shall be clean leaf compost and mineral soil should be predominantly in the loam to sandy loam texture range. 5. Prior to the placement of the soil medium, a professional wetland scientist or licensed soil evaluator shall inspect the replication area and proposed soil medium to insure that the proper elevation has been reached and the material is suitable. 6. The soil medium shall then be placed in the replication area until the surface reaches the finish grade shown on the design plan. Following the placement of the soil medium, a wetland scientist shall inspect the replication area to determine if the area is suitable for planting. If unsuitable material is encountered, it shall be removed to a depth of 1 foot and be replaced with suitable material. Soil depths and structure, surface topography and hydrology in the wetland replication area shall coincide with the adjacent wetland to the maximum extent possible. 7. The replacement area shall meet the performance standards in 310 CMR 10.55 (4)(b)• 8. Replication species selected shall be "inkind" i.e. the replacement area shall be generally similar to the surrounding species composition, cover and structure of dominant species unless modified by the NACC (See Replication Species List). The applicant shall obtain additional plantings of indigenous species from a nursery specializing in the propagation of wetland plants. The wetland replication area shall be planted ONLY with native species indigenous to North Andover. 14 Lorraine Avenue 4 9. The representative species shall be planted in the replication areas shown in the above details using a poachers shovel and a mixture of composted cow manure or peat moss. Species shall be planted at the beginning of the growing season. Plantings shall be watered as needed to prevent desiccation during their initial growing season. 10. The replication areas shall be raked with a steel rake and then be seeded with ERNMX-251 or equivalent at the specified application rates. Following the seeding a thin layer of straw shall be spread over the replication area. 11. A wetland scientist shall monitor the soil horizons and depths,plant community composition and hydrology of the wetland replication area. Monitoring shall occur in May and September for two complete growing seasons following completion of construction and it shall continue beyond that date if not established according to the performance standards in the Wetland Protection Act and NACC Wetlands Protection Bylaw at the end of the second complete growing season. Temporary Access & Temporary Wetland Alteration/Restoration 1. Access to the proposed replication area shall be across the wetland resource area between wetland flags 91 &63. The ground surface in this area is firm and it is the narrowest section of the wetland so the temporary wetland alteration will be minimized. 2. Logs or wood planks shall be laid down to create a temporary"corduroy road" access path that will allow construction vehicles to drive back and forth across the wetland during, and only during, construction of the wetland replication area. If applicable, a row of silt fence shall be installed as shown on the proposed site plan under the direction of a wetland scientist and approved by the conservation agent during the pre-activity meeting. 3. Following the construction of the wetland replication area the wood planks and/or logs shall be removed from jurisdictional areas. 4. The temporary access path shall be returned back to it original grade preferably using hand tools or with the use of a small machine. 5. The access path shall then be raked, using a steel rake, and then be seeded with ERNMX-251 or equivalent at the specified application rates followed by a thin covering of straw. 14 Lorraine Avenue 5 6, A wetland scientist shall monitor the temporary access road restoration effort ill May and Septembe,- for two complete growing seasons following corn pletion of construction and monitoring shall continue beyond that date if the area is not established according to the perfbrman(,-,,,e standards in the Wetland Protection Act and NAC C Wetlands Protection Bylaw at the end of the second complete growing season.
