Eight(8) copies of this request are being forwarded to you. The Order included the following work, as referenced in Special Condition 27: "expansion,regrading and realignment of the existing driveway, installation of a stormwater infiltration trench, stormwater infiltration system, construction of a retaining wall, 4-foot wood fence and walkway, removal of the existing pool and 5-feet of existing deck,placement of hot tub on the deck and the planting of shrubs...." This work was depicted on a plan prepared by Design Consultants, Inc: dated July 20, 2001 and last revised on 11/21/01. The amendment includes revisions to the original plan, though the general intent and scope of work is very similar. This work is indicated on a plan prepared by McKenzie Engineering Group, Inc. dated March 24, 2004 (sheets 1 and 2) and included as an attachment. All of the work is intended to provide maximum protection to wetland resources, while addressing on-going stormwater runoff and erosion problems at the site. The following modifications to the original plan are proposed: 1. Revised driveway layout—The original plan called for 1,500 square feet of paved surface. The driveway has been revised to reduced in size by 650 square feet and 810 square feet is proposed to consist of pervious pavers. This work does not extend any closer to the wetlands than the originally approved plan. The existing retaining wall along the driveway edge is not proposed to be relocated as originally proposed. The paved area along Salem Street has been eliminated. 2. Stormwater Infiltration System—revised from an infiltration trench to a subsurface infiltration system. Details of the system are shown on the site plan. Sizing calculations are included as an attachment. 3. Installation of fencing—reduced from 175 linear feet to 136 linear feet. 4. Revised deck—the proposed new deck is reduced from 960 square feet to 445 square feet(rear deck setback to wetlands increased from 5 feet to 15 feet). 5. Revised brick walkway in fronts—Due to the elimination of the revised retaining wall along the driveway, the walkway much be realigned. Square footage within the riverfront area is similar to originally proposed condition. 6. Buffer Zone Enhancement Plan—the number and type of plantings is the same,but the location is proposed to include a larger portion of the western corner of the site, Plantings are not proposed within the fenced area proposed to be used as a dog turnout. This planting plan includes removal of invasive Japanese knotweed (Polygonum cuspidtatunz)to enhance habitat value of buffer zone. 7. Revised Erosion Control - In order to minimize impacts to the wetland from installation of erosion controls,it is recommended that siltation fence be substituted for haybales. This will minimize introduction of weed seeds into the wetland and reduce the total area of impact as the silt fence can be set closer to the limit of work. The following work was not included in the original plan, but is proposed to be included as part of the Amended Order of Conditions: 1. Removal and replacement of the rear retaining wall Presently, the railroad tie retaining wall at the wetland edge is in disrepair and is in danger of collapse. This work was apparently not included in the original Order of Conditions, (the final plan is unclear as no note is provided indicating this work). Repair of the wall is believed to be important for the protection of the wetland, since its failure could result in a significant impact to the adjacent wetland. Also, under current conditions sediment and salt from stormwater runoff from the driveway washes directly into the wetland at the eastern edge of the retaining wall (see attached photos). The applicant proposes to remove the existing wall and construct a more durable interlocking stone retaining wall and to regrade the existing rear yard so that stormwater is infiltrated prior to discharging into wetlands. Approximately 18 feet of the existing retaining wall in the western portion of the site will be removed and not rebuilt. Approximately 18 feet on the eastern portion of the site, east of wetland flag 6 will be removed (some of this wall is not on the applicant's property) and reconstructed further from the wetland, extending to meet the end of the driveway. Upon completion of construction,the rear yard would be reseeded and restored. 2. Rear Walkway—In order to provide safe access to the rear door and deck, construction of a 3-foot wide brick walkway is proposed. 3. Planting Bed-Installation of a small (3-foot wide),mulch planting bed along the upland side of the proposed new retaining wall.
