APPOINTMENTS 7:15 PI1 —Title V variance — 36 Wilson Grove. Glen Harrington stated that the proposed design plans have been submitted for the septic repair at 36 Wilsons Grove. The property only contains 3,376 square feet of land so the main variances are setback related. As part of the technical review, Mr. Harrington recommended that the-soil Absorption System have a deeper effective depth so it would have more storage capacity. The plan was originally designed with lover profile plastic chambers, but they only have a three inch effective depth. Mr. Harrington suggested a 1' drop to'groundwater, from 5'to 4' under maximum feasible compliance, as he felt this would be a better design where the other system would not have enough storage. Matt Tavares of BSS Design, representing 36 Wilsons Grove, introduced himself to the Board. Mr. Tavares commented that there are no added bedrooms, and the property will remain as a -bedroom system. The existing septic system failed due to a septic inspection for the purpose of a property transfer. The proposed site will contain a 1500-gallon septic tank, a D135 distribution box, 16 high capacity H- o infiltrators, and an impervious 40 rail barrier between the house and the septic system. Mr. Tavares is requesting six variances: 1. An 8' variance from the south abutter to the proposed septic tank. An ' variance from the southern abutter to the proposed Soil Absorption Systema 3. A. 15' variance from the existing house to the proposed Soil Absorption system. 4. A 1' variance from the existing bulkhead to the proposed Soil Absorption System. 5. A 5' variance from the existing house to the proposed soil Absorption system in the back yard. 6. A ' variance from the northwest abutter to the soil Absorption System in the back yard. 1r. Tavares provided Mr. Harrington with the certified green cards that were returned by-the abutters. Mr. Harrington requested that the variance for the I' drop to groundwater, from b' to 4 , be indicated on the plan. Brian Baumgaertel commented that he would like to see a liner on the abutting south side to prevent gas migration particularly if there is a full basement since the o' requirement to a cellar gall cannot be met. Mr. Harrington stated that there is a cesspool on the abutting property and would not be impacted by the septic tank. Mr. Harrington would prefer not to incase the entire leaching with the liner because it prevents the effective use. Gerhard Wagner and Elizabeth Wagner of 40 Wilsons Grove, the abutters on the south side, introduced themselves to the Board. Mr. Wagner remarked that he does not have a cesspool but a 1500-gallon septic tank with a leaching field.
