The Limits of Inland Wetlands are in the same location as the High Water Mark of Gardner Lake and westerly property line of the subject parcel as noted on the project design plans (See attached plans and letter from Joseph Theroux, CSS). There are significant limitations associated with this sanitary repair project including: - Steep slopes to the west, south and east. - The sub-standard size of the lot(0.23 acres). - Required 75 foot separating distance between wells and septic systems on the subject lot as well as the lot to the north. - The location of the shoreline of Gardner Lake (Limit of Inland Wetlands) adjoining along the westerly boundary of the subject lot. - Grading requirements down-slope from a leaching field is an especially significant limitation in the case due to the steep existing grades. - For repairs such as this,the State Health Code allows a septic system to be located not less than 25 feet from a water body. All these factors have contributed to the proposed septic system repair design. The Uncas Health District,the site contractor and the design engineer all agree that the proposed design is the best solution given the circumstances. It utilizes a system that provides a very high effective leaching area per square foot of leaching trench resulting in the smallest possible footprint for the septic system. Due to the size of the existing lot(0.23 acres), dwelling and well,the proposed septic system will be located within 50' of the edge of the lake,but not less than 25'. A waiver from the State of Connecticut Department of Public Health is required to install the septic system less than the minimum 75'from the owner's existing well(waiver requested to allow 70' from mantis units and 63'from the septic tank). 410 The area of disturbance within the upland review area is 1,762 square feet (0.04 acres). The total area of disturbance for the project is 1,856 square feet(0.043 acres). No activity or disturbance of Regulated Inland Wetlands is proposed. Proposed improvements/activities include: - Tree removal in the area of the proposed sanitary repair system. - Excavation for and installation of a 1,000 gallon septic tank and 25' of Mantis double-wide 100 units_ - Associated grading in accordance with the State of Connecticut Public Health Code. - Stabilizing all disturbed areas. The approximate time from start to completion of the project will be approximately 30 days. Improvements will be constructed using mechanical equipment including an excavator, skid steer, and similar equipment. Septic sand will be brought to the site for construction of the Mantis double-wide 100 units. Material excavated from the leaching field and septic tank areas will be used for required grading. Excess material, if any, will be removed from the site in a lawful manner to a suitable location. The topography of the property varies from relatively flat up on a plateau where the building and proposed septic area is with 33% slopes to the south and 90%to the west toward Gardner Lake. The soils in the development area according to the NCRS Web Soil Survey generally consist of hinckley loamy sand, 3-15% slopes. The proposed activity is located in sub-drainage basin#3906-00. Erosion controls that will be implemented to minimize soil erosion and control sediment include: - Sediment fence or wood chip berm downgradient of all construction areas. - Jute netting or approved equal shall be used to stabilize all slopes greater than 2:1. • • Sanitary Repair Doyle Rd House was built in 1925 and the septic does not meet any of today's requirements. The existing septic is failing and needs to be replaced. See email from Uncas Health District. There is no other portion of the property where it can go and it also needs a waiver from the State. This could be considered an emergency situation, see Uncas email, which means it could be approved at the meeting tonight. Commission should determine if they believe enough E&S measures are being taken. Draft Motion After giving due consideration to all relevant factors including those in Section 10 and or Section 4 of the Montville Inland Wetland Regulation and Section 22a-41 of the Connecticut General Statutes, I move to approve application 220 IWC 7 Donald Raitz: Septic repair on the property located at 157D Doyle Rd (Assessor's Map 57 Lot 10D) as depicted on the plan titled "Sanitary Repair Plan Prepared for Donald Raitz Property of Betty K Raitz, Trustee located at 157D Doyle Rd, Montville Ct prepared by Star Surveying, LLC dated July 6, 2020" This is a conditional approval. Each and every condition is an integral part of the Commission decision. Should any of the conditions, on appeal from this decision, be found to be void or of no legal effect then this conditional approval is likewise void. Should any of the conditions not be implemented by the applicant or his successors within the specified pelluit time period, then this conditional approval is void. Conditions of approval are:
