This proposal has • also been submitted to the Town Planning Board for a Freshwater Wetlands and • Water Courses Permit. Mr. Trachtman noted a few corrections in the • Environmental Assessment Form: A-19: it is in a critical environmental area; • B-2: spoils. will shrink to 5,600 cubic yards after drying, which will be the • volume actually removed; Part 3, y g' page 3: hours of operation will be 8 a.m. to 6 p.m. • • A lengthy discussion of the dredging work ensued. The lake would be drained and a channel established through it. After the top layer has dried,• the surface would be scraped off and the remainder allowed to dry. After © another couple of months, it would be dredged again. It was noted that the lake would be restored to its original depth of 4 feet, with some areas a• little deeper (i.e. , near bridge) . Mr. Schoenberger stated that it would be wise to remove as much as possible to prolong the time before future dredging • Address Correspondence to CZM Commission, 740 West Boston Post Road, Mamaroneck, NY 10543 (Phone 914-381-6133) I CZMC Minutes - 3/22/88 L • 0 is needed. However, Mr. Trachtman explained that the lengthy drying time was the limiting factor for removing more sediment. The trend for redredging the lake is about every 15 to 20 years. It would essentially be the same following this dredging unless an indepth analysis of Y sedim ent load contributions is conducted and 'mitigation measures impl emented. e P nted.

They J hope to begin draining in April and start the fir st stage of dredgingin June. one. Great concern was exp ressed P d over the proposed loweringof the Larchmont Reservoir to assist the drying procedure. Mr. Trachtman explained that the would be dropped 6 to P i PP 8 fee t in April and nd again in September, which are the critical drying periods. In between these months, the Reservoir would be kept at 3 feet below spillway. Mr. Trachtman said that a 6 to 8 foot drop would expose approximately 10 to 15 feet of shoreline. Or.•twin Meyer noted that the residents surrounding the lake would - � the loweringof the Reservoir be vary upset about since it would be aesthetically displeasing. Jim Johnson and Elizabeth Lehman noted that bass spawning and wan'and duck nesting occur from April through June. Significant lowering of the Reservoir at this time coul d, there fore,efore be detrimental to these wildlife populations. Although the Reservoir has been dropped other times, even as much as 12 feet when they needed to inspect cracks in the dam, it was only for a very short period. Holding waters on the East Branch of the Sheldrake River was offered • as an alternative, but Mr. Trachtman indicated it would not be sufficient since the West Branch is the major contributor. Mr. Meyer suggested putting • a pipe in place of the proposed channel through Gardens Lake to allow the 0 hydrology to continue as normal. Mr. Trachtman felt that this would not be feasible, however, because it would complicate the series of trickle channels that would be made to help the spoils drain. Mr. Altieri observed that the • Town had originally considered dredging it while wet, which would be much more messy, and would take only a month or so, but there was a great deal of • local opposition to the plan (including CZMC) and the State DEC will not approve the spoils for dumping at the Hommocks, thereby making it necessary • to 'dry the material before transporting it over greater distances. Mr. Trachtman added that the Soil and Water Conservation District had reviewed the proposed project and commented that it is better to dredge it dry to prevent downstream siltation. Legal questions arose as to whether or not the Town or Village had the authority to lower the water level, to which Mr. Altieri replied that there • is no formal agreement, but there is a general policy that 36" to 42" of lowering would be allowed normally, more only for major events, such as hurricanes. Mr. Johnson concurred that this level of adjustment of the water level is within the Village of Larchmont's rights; this had been determined by the Village of Larchmont when they were initially acquiring the property. . Mr. Allen and Mr. Meyer noted that other water bodies upstream of Gardens Lake needed dredging, such as Dickerman's Pond, the Reservoir, and Carpenter's Pond, and if they were to be dredged in the future, then all the silt would be flushed right back down to Gardens Lake. Mr. Trachtman responded, stating that a silt trap installed at the bottom of the falls, just before the entrance to the pond, would help mitigate siltation from upstream disturbances. Mr. Schoenberger suggested advising the New Rochelle Waterfront Revitalization Committee since those water bodies upstream of Gardens Lake lie primarily in the City of New Rochelle. Mr. Johnson suggested taking advantage of the lowering of the Reservoir to do some • improvements to the Reservoir as well, such as installing a catchment at the head of Sheldrake Lake and general clean up of the shores. Mr. Meyer noted -2- CZMC Minutes - 3/22/88 1 C that there is a pre-existing valve near the dam of Gardens Lake, which could be fixed when the water is diverted to help regulate the water level. Constance Livingston, g on, a Town resident srdent and member Reservoir, noted that the of the Friends of the • waterway which times been low runs in front of her house has at and durin g g the summer it would be very smelly and full of mosquitos. The Commission gave its r s approval to the prop osed dredging project€ two conditions: (1) that the Town investigate the idea o f the repairing salve and (2) that the Town consult with the Friends the of the Reservoir Larchmont Reservoirand Committee urttee before finalizing and proceeding.

Ms. Price commiended the CZMC for their thoroughness in que: tioning the 0 proposed project. Cambridge Court - Mrs. Johnson reported that she and Mrs. Fredston had attended the Village Planning Commission meeting and that the Planning Commission approved the subdivision, despite opposition to the blasting that would be necessary. The Commission only required that the contractor inspect all the houses within 300 feet of the blasting for insurance purposes. LWRP PROJECTS Harbor Security - Mr. Allen informed the Commission that h€ had received a copy of a letter, dated February 29, 1988, that was sent. by Fred Kellogg, Village Engineer, to Jim Staudt, Village Attorney, which provided documentation to the assertion that jursidiction of the waters off the coast of Larchmont, beyond the mean high tide line, does indeed belong to the Town of Mamaroneck. Mr. Allen wrote to Mr. Staudt on March 7, acknowledging the need to rectify the present policing situation before ith the Constable Program. Mr. Young indicated that the Village t,Board1iofceedig wTrusteesBay have written a letter to Mr. Allen concerning the proposed program and that he would be receiving it shortly.

Some CZMC members mentioned that they had not received a copy of either phases of the Master Plan Update. Ms. • Price indicated that originally some Coastal Zone Management Committee members were involved with the Joint Planning Commission when they were beginning the Update, but apparently later communications fell through. The public hearing on this has already been held and some policies already approved. However, the plans as a whole have not yet been passed by the Town and Village Boards. Ms. Price has instructed the Town Clerk to make sure C that each CZMC member has received a copy of both Phase 1 and Phase 2 reports. Mr. Young will check to see if the Village has sent a communication to CZMC for their comments.

Item 1, "Action against • sewage pollution, " is being currently worked on by the municipalities. Item • 2, "Flood control in the Sheldrake and Pine Brook-Premium areas," is • ongoing. Item 3, "Silt and trash traps; catch basin improvements," requires • the Commission to keep presure on the municipalities to install them. In • this regard, Mrs. Johnson noted that Boston Post Road is a state road and • that maintenance of catchment placed there may be state responsibility. Item • 4, "Adoption of Erosion and Sediment Control Laws, " and item 5, C "Rehabilitation of East Creek, " needs attention by the Commission to advise the municipalities. Mrs. Johnson informed the Commission that she and others are working on getting easements for parts of the Sheldrake River. She also • mentioned that the Village of Larchmiont needed to be made aware of Robert • • • -4- a i CZMC Minutes - 3/22/88 • Hohberg's water quality reports.
