3/8/2007 CAYUGA COUNTY ENVIRONMENTAL HEALTH DIVISION Subdivision Review Checklist The Design Engineer should check the following list prior to submitting the subdivision plan to the Environmental Health Division of the Cayuga County Health and Human Services Department. Any item which is answered by “No” should include an explanation in the engineer’s report. This checklist is a guideline and is not intended to cover every aspect of Part 74, 75A, Appendix 5B or any other regulation covering subdivisions. The checklist should ensure that the basic application requirements are met but specific details of each project will have to be reviewed in full by department staff. I. An initial submission must include the following items: Yes No A. A check made out to the Cayuga County Department of Health in the amount of $30.00 per lot in the subdivision if public water and public sewer connections are required. A $55.00 per lot fee is required if private sewage and/or private water supply systems are required. A separate $100.00 fee is charged for public water supply plan review. Please note that if the proposal involves public sewers, plans should be forwarded to NYSDEC Region 7 for their review and approval B. Application Form HD, GEN 157, completely filled out and signed by both the engineer and the applicant or a responsible official of the company or corporation which is applying. C. Proof of preliminary planning board approval, if applicable. D. Proof of SEQRA Compliance E. An engineer’s report. F. Three copies of legible and complete subdivision plans signed and sealed by the design engineer. G. Is the subdivision or any portion is within a designated flood-plain or wetland? If yes, show area on subdivision plan and discuss in engineering report. H. Owner certification that there is no soil contamination at the site proposed for reality subdivision. I. Has the Stormwater Pollution Prevention Plan been reviewed by the New York State Department of Environmental Conservation? II. The Engineer’s Report must contain the following information: A. Description of the project. B. Description of the site. C. Description of the proposed water supply quantity, quality and distribution. D. Description of the proposed sewage collection and treatment system. E. Will subdivision be supplied by public water? a) Water Supply application submitted? b) Description of system including volume of water and pressures available within the subdivision. ---PAGE BREAK--- 3/8/2007 Yes No c) Does the municipality agree to accept ownership of any new water lines? d) Water distribution plan submitted? e) Are location, size and material of water services line included? F. Will the proposed subdivision be supplied by private wells? a) The subdivision is located outside of an existing or proposed water service area. b) The subdivision is not reasonable accessible to an existing or proposed water service area. c) This section of the proposed subdivision, together with future sections, will consist of less than 50 lots or less than 200 residents in the aggregate. d) The ground waters are potable and individual wells can produce an average yield of 5gpm or have appropriate storage capacity. e) Is the following information regarding proposed individual water supplies addressed : 1. Site selection (ground slope, rock, outcrops, distance from sewage treatment system, etc.) 2. Type of supply proposed (drilled well, other) 3. Overburden – type and depth. 4. Logs of representative wells 5. Anticipated depth of wells. 6. Water quality data from one or more adjacent (within 500 feet) or on site representative wells including results for: Total Coliform Bacteria, Nitrate, Nitrite, Iron, Manganese, Hardness, Alkalinity, Turbidity, pH, Sodium, Lead, and volatile organic chemicals. Additional tests may be required for specific concerns by the County Health Department. 7. The number of tests wells required will be as follows: 5 – 10 lot subdivision, 1 well; 11 – 20 lot subdivision, 2 wells; and 21 – 30 lot subdivision, 3 wells, etc. 8. Minimum yield demonstrated. A well for a private dwelling should have a minimum well yield of 5gpm. Well yield should be determined in accordance with Appendix 5-B of Subpart 5-1 of the NYS Sanitary Code. The yield test should be conducted at a constant flow rate during “drawdown and throughout the four hour stabilization period” with periodic water level observations made and recorded during drawdown, stabilized pumping, and recovery periods. 9. Treatment requirements, if necessary, including equipment specification f) Construction Details for Drilled wells 1. Detail of well indicating diameter and depth of casing, pump, water lines, electrical lines, pitless adapters, well seal, depth of grouting. 2. Is height of casing at least 12” above the ground. 3. Well detail should meet requirements of Appendix 5B of Subpart 5-1 of the NYS Sanitary Code. ---PAGE BREAK--- 3/8/2007 Yes No 4. Is the well located on an area of seasonal flooding or surface water contamination? 5. Is there a minimum of 50 feet between wells and subdivision boundaries provided? 6. Is a minimum of 15 feet between wells and lot lines provided? G. Design of the individual sewage facilities located on each lot a) Are the number of bedrooms considered in system designs specified? b) Is the disposition of waste water from water treatment, if any, i.e., water softener specified? c) Are tabulated soil data of deep pit tests including test number, test location, soil characteristics, color, depth of each layer, total depth of the hole and depth at which ground water and/or rock is encountered included? (One deep test pit for each proposed sewage treatment system for each lot.) d) Are tabulated results of percolation tests taken including the lot location, test number, test location, depth of hole, soil characteristics, watch time at start of each test, time required for the water to drop 1” and any remarks included? Include data on all runs until stabilization occurs for each lot. (Two percolation tests within each sewage treatment area for each proposed sewage treatment area for each proposed sewage treatment system.) e) Are there four feet of usable soil above rock, ground water or impermeable soils? f) Are septic systems located in areas not subject to flooding and/or influence from storm water discharges? g) Are minimum separations appropriately and clearly noted on the plans h) Is the maximum size house that can be accommodated by sewage treatment design for each lot specified in plan. i) Are the number of lines, the size, spacing and length of laterals for each lot specified? j) Is sufficient area for a 50% expansion of the sewage treatment system specified? k) Is grading required to make sewage treatment area usable? l) Has consideration been given to locating systems on lots in such a manner as to allow for connections to future sewers? m) Is surface water diversion from sewage treatment area shown? H. General Description of existing and proposed drainage, including landscaping and grading required to minimize soil erosion and prevent conflict with proposed sanitary facilities. a) Has the developer met the requirements of NYSDEC Phase II Stormwater requirements? b) Has the Cayuga County Soil & Water reviewed stormwater and erosion plans?
