The meeting commenced at 8: 11 P.M. Members present: Robert Schoenberger, Chairman Elinor Fredston Wallace Irwin Mary Anne Johnson Arthur Katz Phyllis Wittner Others present: Stephen V. Altieri, Town Administrator Howard Sloane, Town resident, 8 Oak Lane Claudia Ng, Environmental Assistant East Creek Mr. Irwin reported that the on July 10, the Village of Larchmont Board had approved the designation of the Village's portion of East Creek as a Critical Environmental Area (CEA). Following the Town's similar action in April, all of the open portion of East Creek and land within 10 feet of its banks now has CEA status. Woodchips at Hommocks Field Mr. Schoenberger expressed objection on behalf of the CZMC to the storage of the Town's Woodchips at the end of Hommocks Field, near the marsh. It was noted that communication to the CZMC of actions conducted by the Town needed to be improved. An overall plan for East Creek and the Hommocks-Hampshire Complex was suggested be developed and then presented to both the Town and Village Board. Gardens Lake Dredging Mr. Sloane voiced his opposition to the Town proposal to dispose of the dredge spoils from Gardens Lake on Hammocks Field. Mr. Altieri informed the Commission that the Town is now seeking the opinions of the Conservation Advisory Commission and the CZMC on the proposals developed by Malcolm Address Correspondence to CZM Commission, 740 West Boston Post Road, Mamaroneck, NY 10543 (Phone 914-381-6133) CZMC minutes - 7/14/87 Pirnie, Inc. The Pirnie report has also been referred to the County Soil and Water Conservation District and will be referred to the Department of Environmental Conservation and the U.S. Army Corps of Engineers. He pointed out that, according to the report, the soil analysis of the pond's sediment poses no dangers for disposal and that the soil from the berm at Hommocks was considered to be good soil for cover material. He stated that the roads would be able to handle the loads since it will be carried in 10-20 yard capacity trucks; and that any garbage extracted during excavation of the trench at the Hommocks will be removed as required by Department of Transportation regulations. In discussion, Mr. Katz raised the question of whether the proposed disposal would cause an increase in ground suspension due to the fact that most of the dredge materials are fines. Mrs. Johnson expressed concern over the possibility of substrate being squeezed out into the marsh as a result of repeated deposits. Mr. Altieri noted that other options have already been considered, such as giving the spoils to landfills for capping. However, the current proposal appeared to be the most feasible so far. He commented on the urgency of the dredging project and stated that the Town could really not postpone it any longer. Mr. Schoenberger stated that alternatives for disposal have not been seriously addressed and that it remained to be proved that using the Hommocks as the dump area would not be detrimental to the Hommocks Marsh, a designated Critical Environmental Area. Mr. Altieri will convey to the Town Board the CZMC's concerns regarding potential impacts from dredging, transport and disposal. Army Corps of Engineers Proposed Flume Mr. Altieri gave a brief introduction of the project. In 1977, the Corps conducted a feasibility study of the Mamaroneck, Sheldrake, and Byram Rivers. In this report, they proposed a concrete flume that would run from just above Rockland Avenue to the falls before Gardens Lake. In response to much opposition by residents, the Corps later scaled down their proposal. They now propose to construct a 1,800 foot flume which would still begin near Rockland Avenue, but end just below Briarcliff Road. A levee would be installed at the beginning, in the conservation area, and a stilling basin placed at the end. Some areas would be raised by fill and some land acquisition would be required. In regard to the impact of the project on flooding downstream, Mr. Altieri noted that the Corps plans to eventually pipe the entire lower Sheldrake River under Fenimore Road, directly out to the harbor in the Village of Mamaroneck. The Town portion of the flume project will take at least five years to complete and would cost a total of $3.3 million, with the federal government picking up 75% of the cost and the state picking up half of the remainder. The Town must now decide on whether or not they will support this proposal before the next step can be taken, which is the appropriation of federal funds for design work. Other alternatives, such as a masonry flume, may not meet the federal standards for flood control improvement and therefore, would not qualify for federal assistance. Mr. Irwin called attention to other local flood control measures provided for in the Local Waterfront Revitalization Program (LWRP) for this part of the Sheldrake, such as projects 3 and 4 on pages 80 and 81. He suggested that the mitigation expected from these projects would tend to reduce the need for the flume. Mr. Altieri noted that one of these projects -2- CZMC minutes - 7/27/87 had recently been rejected for county funding. The Commission will continue the discussion at its next meeting. Future LWRP Projects Ms. Ng reported that Randy Lanza of the State Division of Coastal Resources and Waterfront Development had called requesting a list of projects that the CZMC would like to implement in New York State fiscal year 1988-1989. The Commission prioritized its LWRP-related projects and chose three that they felt were the most important to be initiated in the following year. Mr. Irwin, Mrs. Johnson and Dr. Mason will assist in drafting the detailed list (copy to be attached) and will give it to Ms. Ng for immediate mailing. Ms. Ng also conveyed Mr. Lanza's suggestion of having neighboring CZMC's begin working together in order to develop more effective, integrative, and comprehensive plans. Tony's Nursery Mr. Irwin reported that he had written to Mayor Curnin and the Village Board conveying the CZMC's concern regarding the collapse of part of Tony's Nursery's wall into Pine Brook, noting that the incident took place in the Village's Pine Brook Border CEA. Mr. Altieri noted that he and Tom Leddy, the Highway Superintendent, had already talked to the owner of Tony's Nursary about the problem. Mrs. Wittner showed some pictures which revealed the remainder of much debris in the river. Referrals Maloney Residence/Fenbrook Subdivision - Mr. Maloney, owner of lots 19 and 20 and part of 18 in the Fenbrook Subdivision, is proposing to pipe a stream channel that leads into the retention area in lot 20. Dr. Mason was unsure as to whether it would have a substantial impact, but Mrs. Fredston noted that there may be some adverse impact since the surroundings exhibit large coverage of the grounds with impervious matter. For example, she noted that one house had an unusually long driveway. Mrs. Johnson pointed out that she had observed large deposits of mud and puddles on Fenimore Road near Fenbrook Drive and a lot of silt in the water downstream of the Subdivision. Mrs. Wittner suggested the hiring of a consultant for the CZMC, and perhaps in conjunction with the Conservation Advisory Commission, to help provide the technical expertise necessary to comment on the ramifications of the added development. Mrs. Fredston and Dr. Mason will investigate the site and proposal. Winged Foot Estates East Subdivision - A five-lot subdivision is being proposed at 1160 Old White Plains Road. Dr. Mason will review this case for the following meeting. -3- CZMC minutes - 7/27/87 Other Matters CZMC Organization - There was a brief discussion on the need to improve the Commission's consistency referral procedures to make it more efficient. Many felt a need to weed out the inconsequential matters. Mr. Altieri commented that many other agencies have developed manuals with standards that can be used to reduce the need for case by case review of minor proposals and that Ms. Ng is presently working with the Building Inspector to develop such criteria for CZMC consideration. In addition, he reported that a formalized set of procedures for land use review would be presented to the Town Board the following day. This will help smooth out and integrate the review, referral, and SEQR process. Ms. Ng will send copies of this document to each CZMC member. There being no further business, the meeting was adjourned. -4-
