Approval of Minutes The minutes for November 27, 2001 were reviewed and accepted as corrected. 3. Referrals a. Freshwater Wetlands and Watercourses Permit for the Construction of a rear addition at 450 Weaver Street-Block 221, Lot 154 Referred by the Town of Mamaroneck Planning Board David and Joy DeSanto,the applicants and Scott Perry,the building contractor, presented their proposal for a rear addition to their home. The project is located within the 100-foot buffer zone of the Sheldrake River. They are proposing to remove the rear deck of the house and construct a two-story addition. There will be no net increase in impervious surface, because the area under the deck is now concrete. Runoff from the roof of the house currently runs down leaders to splash blocks at the rear of the house. The property is relatively level and water is absorbed in the rear yard. Runoff from the proposed addition will be handled in the same way. As shown on the drawings provided to CZMC,the house is located within the wetland buffer zone. This area is prone to flooding, and several major floods have impacted the neighborhood. A masonry wall is located at the rear of the property. This will protect the Sheldrake River from erosion and sedimentation during construction. Nevertheless, the applicant will also use silt fencing. Debris in the Sheldrake River was visible in the photographs provided by the applicant. The applicants were advised that it is their responsibility and their neighbor's responsibility to keep their portion of the river clear of debris. This will help prevent flooding problems. CZMC finds that the proposed action is not inconsistent with the policies set forth in the LWRP. While the proposed action is located within the wetland buffer zone, impacts on the Sheldrake River will be mitigated by the presence of the masonry retaining wall at the rear of the property. No net increase in impervious surface will result from the proposed action and the masonry wall will prevent runoff from entering the stream. b. Freshwater Wetlands and Watercourses Permit/Site Plan Approval for Bonnie Briar Country Club at 808 Weaver Street,Block 201, Lot 19 Referred by the Town of Mamaroneck Planning Board Materials from the Watershed Advisory Committee 4 Report were distributed to CZMC. This contained information on golf course management and methods of improving water quality and controlling stream bank erosion in Bonnie Briar Country Club (Bonnie Briar). CZMC-1/22/02,Page 2 of 7 Revised 2/28/2002 Steven Grogg, Consulting Engineer for Bonnie Briar presented the proposal for modifications to the golf course. An aerial photograph was used to show the project site. The project has four components: 1. Driving range: The applicant proposes to modify the existing driving range by filling and raising one end,making the driving range more usable and making the opposite end more visible from the tees. The overall length of the driving range will not change. An estimated 20,000 to 30,000 cubic yards of fill will be required. This is a revision of the amount originally submitted to the Planning Board. Trucks carrying fill material will exit I-95 and will come in the main driveway from Weaver Street. Once on Bonnie Briar property,they will follow the club's internal access road, then cut across the fairway on a temporary haul road to the driving range. The temporary road will be stabilized by placing 3/4 inch crushed stone in a 20-foot wide area along the length of the road. They estimate that it will take 6 weeks to deliver all of the necessary fill material using 35 cubic yard trucks. They are proposing to have 3 to 5 trucks per hour. CZMC members were concerned about potential traffic impacts on Weaver Street especially during the morning and afternoon school rush hours,however it is the responsibility of the Planning Board to examine the traffic impacts. The slope created by the raising of the driving range will be planted with natural vegetation and will not be mowed. A depressed area is located between the foot of the driving range and a berm behind the neighbors homes in Coventry Court. The berm will help direct the flow of runoff from the driving range towards the fairway and divert the water from reaching the houses. One neighbor has expressed concern about the potential impacts associated with the modification of the driving range. The applicant stated that the neighbor's property is 5 feet higher than the foot of the proposed driving range and should not be impacted by the proposed change in elevation. It was noted that the area between the berm and the foot of the driving range may contain wetlands that would be impacted by the placement of fill in this area. An inventory of wetlands may have been completed as a part of the EIS prepared for Bonnie Briar several years ago. Elizabeth Paul will review the EIS for this information. 2. Tee 14: The applicant is proposing to use fill material to expand the size of the tee. Trucks will deliver fill material from an access point on Weaver Street. 3. Maintenance staging area: The staging area will be re-graded to make it more usable for the maintenance of the facility. The current staging area is a gravel lot, located on a slope. Bonnie CZMC- 1/22/02,Page 3 of 7 Revised 2/28/2002 Briar proposes to re-grade the site and construct bins to hold sand, soil mix and greens mix. All fertilizers will be stored inside the existing maintenance building as they are now. The applicant will clean up the debris and abandoned cars that are currently at this location. Access to the maintenance staging area site will be from the existing service road off of Weaver Street. 4. Tee for hole 4: The applicant proposes to extend the length of the tee and raise the elevation of the tee,making the play of the hole longer. To access the site and to bring in fill material, the applicant is proposing to enter the golf course from Fenimore Road and cross the Sheldrake River using a temporary bridge structure. It is estimated that it will take one week to bring in and stockpile the necessary fill. During a recent site visit by CZMC members, a location for the temporary river crossing was identified. This location has large stones lining the riverbanks that will protect the banks from erosion. Concrete blocks will be placed approximately 5 feet away from the river's edge. Steel plates will be placed on top of these blocks, crossing the river,with no structures placed within the river's channel. Construction of the tee will require approximately 1,300 cubic yards of fill material that will be brought to the site in 18 to 20 cubic yard trucks. This will require approximately 130 truck trips to and from the site. Other necessary equipment will include a bulldozer, backhoe and small roller. The access road will be stabilized as necessary, depending on the time of year. During the winter, if the ground is frozen, the access road will require less stabilization. If the ground ruts, crushed stone will be placed along the access route. The tee will be constructed with a stone base and approximately 18 inches of topsoil. If larger stone is used as base material, it will be choked with smaller material. The construction will depend on the source and nature of the fill material available. According to the applicant,the source of the fill is not yet known. The material would most likely come from New York State contracts where they are building roads or shopping centers and cutting out rock for foundations. All fill material will be documented and certified according to State law. CZMC recommended that a 6"bed of crushed stone be used to stabilize the access route and that the trucks tires be cleaned before they are permitted to leave the site. Although erosion control measures are not indicated on the plans,the applicant said thatsilt fencing and hay bales will be placed along the river's banks on both sides and along the access roadway. The access road will be covered by CZMC- 1/22/02,Page 4 of 7 Revised 2/28/2002 crushed stone for a distance of 75 feet on either side of the river crossing. This can be picked up and used as fill material later on. CZMC suggested, as a long-term way of protecting the river, that a five-foot wide no-mow zone should be maintained on either side of the river. Dr. Herb Rubin, the Green& Grounds Chairman of Bonnie Briar, agreed to discuss this with the club's Board. Information on Audubon International's Golf Course Certification Program was given to him. He noted that a representative from the United States Department of Agriculture came to speak to their turf advisory committee and had the same recommendation. CZMC asked the applicant if it planned to replace any of the trees being removed. The representatives responded that they are interested in planting replacement trees on the property. The Planning Board will review the tree removals as a part of the Site Plan Approval. The applicant will be submitting a long environmental assessment form and will also be filing a Notice of Intent with NYS as a part of the SPDES permit requirements for construction sites over 5 acres. If approved, the applicant hopes to complete the work in phases. Work on the driving range would be started immediately and would be completed by April 2002. The area would be hydro-seeded and irrigated to speed the restoration process. The maintenance staging area would be done during the summer and the two tees would be started in the fall. CZMC finds that the temporary river crossing proposed by the Applicant is not inconsistent with the policies set forth in the LWRP, provided that the following conditions are met: • the temporary bridge structure is to be kept in place for a period of time not to exceed three weeks; • the temporary bridge is located as indicated on the site plan; • no part of the bridge structure is to be placed inside the river channel; • silt fencing and hay bales are to be installed and maintained along both sides of the Sheldrake River for a distance of no less than 75 feet on each side of the bridge; • the access route is stabilized using 3/4 inch crushed stone for a distance of 75 feet on either side of the Sheldrake River; and • a stabilized construction entrance is located at the Fenimore Road access point. In addition, CZMC recommends that the Planning Board consider the potential impacts associated with construction traffic to and from the project site, including the hours of operation, truck routes from highways, turning radiuses and locations of curb cuts. Also of concern are the source and nature of the fill material used, the planting CZMC- 1/22/02,Page 5 of 7 Revised 2/28/2002 of replacement trees, and the implementation of sediment and erosion control measures during and after construction. CZMC strongly recommended to the applicant that a no-mow zone be established along the Sheldrake River as a method of improving local water quality and reducing flooding. The Applicant stated that it was willing to consider riverbank restoration, including the concept of the no-mow zone. 4. Liaison Assignments CZMC members were given liaison assignments to the various boards and committees within the Town and Village. Liaisons are responsible for reviewing the agenda and attending the meetings if any relevant topics are on the agenda. At the meeting, the liaison should answer any questions and recommend the referral of the project to CZMC, if appropriate. 5. Open Space Inventory a. The Village Board of Trustees has asked that CZMC not circulate the proposed access letter to Village residents because there are very few pieces of land that they feel qualify for preservation and they would prefer to specifically identify any appropriate properties and contact them individually. Elizabeth Paul reported that she had recently attended a meeting of the Westchester Open Space Alliance at Teatown Lake. The topic was how to introduce open space inventories to residents and how to acquire property or establish conservation easements. The speakers did not recommend mailing letters to residents. Instead, they suggested sending newsletters, hosting a hike or a meet and greet. The Commission discussed the fact that in a small community such as this it is possible to identify someone who knows the property owner and arrange for an informal visit to the property. At this point the list of parcels will be reviewed before taking any further action. b. Many of the open space packets have not yet been completed. We need these completed and returned as soon as possible. 6. Old Business a. Marbourne Drive Stormwater Detention Facility A letter was received from Steve Altieri, reporting that representatives of the Town visited the stormwater detention facility as suggested by CZMC, and determined that no maintenance was required at this time. If necessary, if any work needs to be done in the future, access to the facility will not be prevented by the proposed construction. 7. New Business A member of the NYS Department of State will be invited to attend a joint meeting of both our CZMC and Mamaroneck Village's CZMC as a review of the responsibilities of CZMC. CZMC- 1/22/02,Page 6 of 7 Revised 2/28/2002 Flint Park Conservancy newsletter was received. The Conservancy indicated that it would like to do work with the wetlands in the back of the park. CZMC discussed inviting the members of the Conservancy to a meeting to discuss what they are considering. The question of access to the Sound via Village of Larchmont owned property located on Point Road was raised in response to a letter to the editor that appeared in several local papers. This item will be on the agenda next month. The meeting was adjourned at 10:00 p.m. The next scheduled CZMC meeting will be held on February 26, 2002. Anyone unable to attend this meeting should contact Elizabeth Paul at(914) 381-7846 or at conservationdept@a,townofmamaroneck.org CZMC— 1/22/02,Page 7 of 7 Revised 2/28/2002
