IW#460 - Stonegate Associates - Proposed 76-Unit Senior Residential Development involving excavation, filling regrading and placement of structures in and within 100 feet of wetlands and watercourses. Property located off of Mayfield Drive, West View Drive, Pine Hill Road and West Shore Drive (Map 79 Lots 11, 12, 13 and Map 96 Lot 11) Zoned R-44 [Submitted March 29, 2006; Received April 4, 2006; PPE April 18, 2006; EMPHCD July 18, 2006; MPHAD August 22, 2006] After lengthy discussion, a motion was made by Agent Poirot and seconded by Agent Wawer to approve IW#460 with the 10 standard conditions, in addition to the following 19 as amended during discussion:
11. Units #14, 16 and 18 are to be eliminated, modifying the total number of units from 76 to 73, as shown on the site plan entitled "Overall Layout Stonegate, Prepared for Stonegate Associates, Enfield, Connecticut"; dated 2-14-06; revised through 7-17-06; Sheet 2 of 33; Prepared by Wentworth Civil Engineers, LLC, 177 West Town Street, Lebanon, CT 06249 (Exhibit #59). All required approved plan sheets, including but not limited to sheets 2, 7-10, 12, 19-22, 24, 26-29, shall be revised to reflect this reduction in units and change in locations of basins and phasing lines, prior to filing of the mylars;
12. Those portions of the total site indicated to be conservation easement shall be first offered to the town as an easement or restrictive covenant. The Easement language shall be approved by the Town Attorney and filed prior to the issuance of the first Certificate of Occupancy. Conservation easement markers shall be installed in accordance with Town requirements, by a licensed surveyor, at the applicant's expense. Easement markers will be provided by the Planning Department. Where no trees are present greater than 6" dbh, easement markers shall be placed on 4"x4" wooden posts to demarcate the easement boundary. Should the Town Council decline the acceptance of the easement or restrictive covenant, a notification shall be placed on the land records that indicates the extent of wetland and watercourse resources on-site and the regulations governing those resources, including the prohibition of live vegetation removal and disposal of refuse and/or yard waste within 100 feet of wetlands and watercourses.
13. This project is approved in five (5) phases as shown on the approved plan set. Fore each phase, the base course of asphalt must be installed and all exposed areas surrounding the unit are temporarily or permanently stabilized prior to the Wetlands Agent signing off on any certificates of occupancy. Should stabilization not be possible due to the time of year, a stabilization bond will be required to be posted by the owner in the amount of $500 for each unit prior to the Wetlands Agent signing off on the Certificate of Occupancy. Phasing plan narrative on Sheet 30 of 33 shall also be amended to eliminate the construction of 2 model homes in phase 3;
14. Limits of disturbance for each phase are to be clearly marked in the field in accordance with the approved plans and approved by the Wetlands Agent prior to the commencement of any vegetation removal. Construction fencing shall be used to identify the limits of disturbance adjacent to approved crossing areas;
15. For each phase, all perimeter and approved crossing erosion and sediment controls and construction fencing must be in place prior to the Wetlands Agent signing off on any building permits;
16. In-stream and in-wetland construction activities associated with the approved crossings shall take place only during low flow conditions (July 1 through September 30) to minimize excessive erosion and sedimentation as a result of excessive runoff and heavily saturated soils. Any dewatering required shall occur within the approved limits of disturbance and not be directly discharged into wetlands or watercourses. Where diverted runoff is expected to be carrying a sediment load, the runoff shall be released to a sediment impoundment prior to discharge to wetlands or watercourses. Construction access to the east side of the Stonegate Drive crossing at Sta.11+75 shall be from the existing crossing at Sta.37+40 (Westgate Drive). No construction equipment is permitted to cross through the wetland areas unless otherwise indicated on the approved plans;
17. Wetland Creation plans are approved in accordance with the May 11, 2006 Report from REMA Ecological Services (Exhibit 24). Referenced plans: Sheet M-1 and M-2 entitled "Landscaping Plan for Proposed Wetland Mitigation Showing Approximate Locations for Proposed Plants and Seeding Areas Wetland creation"; dated May 11, 2006. Westgate Drive wetland mitigation is approved in accordance with the details listed in the June 6, 2006 report from REMA (Exhibit 45) including mitigation area details, including planting notes, installation, follow-up maintenance and monitoring and planting materials lists;
18. A 'Wetland Enhancement Bond' shall be posted for both created wetlands, all detention basins, infiltration basins and buffer/crossing enhancement plantings. Bonding shall be calculated using the cost of plantings, plus a 50% mark-up for installation and labor. The bond amount is to be set by the Wetlands Agent and the full amount posted prior to the issuance of any building permits. Bonding is permitted to be phased in accordance with the approved phasing plans (for the purposes of bonding, the wetland creation area in the utility ROW is part of Phase I). Timing of release of the bond is after two full growing seasons and submittal of the second Annual Monitoring Report as required on sheet M-2 of the Wetland Mitigation Plan submitted by REMA(Exhibit 24). Should the report identify problematic conditions, the bonding will be held for an additional year, or until a favorable report is submitted by the Wetland Scientist;
19. At the applicant's expense, a Wetland Scientist must be hired to oversee each approved crossing construction (including temporary diversion construction and maintenance) and temporary and permanent stabilization in accordance with the 2002 CT Guidelines for Soil Erosion and Sediment Control. The Wetland Scientist must also oversee the construction of both wetland creation areas and all detention and infiltration basins, as well as all associated mitigative plantings, in accordance with the approved plans and reports. Upon the completion of each crossing and wetland mitigation area, the Wetland Scientist shall submit a report to the Agency to verify completion in accordance with the approved plans;
20. A Baseline Water Quality Monitoring Plan and Construction Water Quality Monitoring Plan are required to be implemented as part of this development as detailed in the May 11, 2006 REMA report (Exhibit #24). In the event of any problems identified, the applicant will implement the necessary controls as recommended by the consultant and/or Town Staff. Interim monitoring reports are to be submitted to the Agency as required;

A copy of the document must be provided to the Enfield Department of Planning before the Wetlands Agent may sign off on the first building permit;
23. The Stormwater Runoff Management Plan on Sheet 33 of 33 is to be followed for long-term maintenance. The following notes shall be added to the appropriate section of the plan: "Supplemental wetland plantings shall be installed if significant portions have not established or after sediment accumulation removal and/or filter berm replacement." and "Any dewatering required for basin maintenance shall not be directly discharged to wetlands and watercourses" and "The responsible party shall maintain up-to date inspection logs and maintenance reports.

A copy of the document must be provided to the Enfield Department of Planning before the Wetlands Agent may sign off on the first building permit ;
24. Permeability tests shall be conducted to confirm the final permeability rates of the constructed infiltration basins to ensure rates are within the acceptable range of ½ " to 5" per hour. The ideal rate is 2" per hour;
25. The revised "typical infiltration basin detail" submitted on July 18, 2006 (Exhibit #61) shall replace the current detail on Sheet 31 of 33. This change shall be added to the final approved plans prior to filing of the mylars;
26. All sedimentation structures (CB3, 17, 29, 39, 46, 53) are to be replaced with hydrodynamic separators. Hydrodynamic structures must be appropriately sized to adequately treat the "first flush" and avoid re-suspension of materials. Sizing calculations must be submitted and approved by the Town Engineer. Quarterly detailed maintenance schedules, as per the manufacturers specifications, must be added to the stormwater management plan on sheet 33 of 33 and incorporated into the management plan documents transferred from the developers to the entity assuming ownership of the common properties);
