ITEM: Public Hearing
Appl. #01-12P, Deming Hill Estates, southerly of Deming Street and northerly of Northern Hill Drive, Residential AA-30 zone
Mr. Peter DeMallie from Design Professionals came before the Commission to represent this application. He explained that the whole project consists of 97-lots and are split into six sections. Sections 1-5 have all been approved and are under construction. Section six consists of 28 acres with 24-lots. The impacts to the wetland are approximately 3,000 square feet. There is also approximately 22,000 square feet of disturbance to the 80’ upland review area. The disturbance to the upland review area consists of 1) sanitary sewer line; 2) construction of a driveway; and 3) utilities on lot #55. All comments by Town staff have been responded to, and plans have been resubmitted.
Ms. Karen Isherwood, a Project Engineer with Design Professionals came before the Commission to address the engineering aspects of the plans. Ms. Isherwood explained that this proposal would be the final phase of Deming Hill Estates subdivision. Section 6A involves the creation of 14 building lots and section 6B consists of 10. There will be an increase in impervious coverage, as required by the Town. The grading has been kept to a minimum in order to reduce any impacts. The landscaping plan has been changed and the seeding schedule within the sedimentation basins, have been revised. Details to the catch basin structures have been revised in order to provide a minimum of 4’ deep sumps. All 24-lots will be served by public water and public sanitary sewers.
The existing sedimentation basin was analyzed to see if it could detain the increase of this site. With minor improvements it was found capable of handling the increase. The sedimentation basin is going to receive run-off from the proposed 19 catch basins. The shape has been redesigned and includes three earthen berms to channel the flow through the bottom of the basin which will increase travel time in the basin and therefore enhance the water quality. The detention basin is designed to be a wet bottom basin. As the water level increases over six inches, it is designed to discharge at the end of the basin and disburse overland into the detention area within the wetlands. The only permanent disturbance within the wetlands, are the two manhole structures and associated pipe.
A cross-country sanitary sewer is proposed to be installed under the existing cart path in order to minimize wetlands impact. Improvements to the detention basin and the installation of the sewer line will be done at the same time in order to limit wetlands disturbance.
Mr. Ed Pawlak a Soil Scientist with Connecticut Ecosystems came before the Commission and spoke of the different habitat he had found on site. Mr. Pawlak also told Commission members that he felt the existing basin should be classified as an enhancement of the wetland conditions and the proposed basin would be classified as a creation of wetlands. The recommended plantings would be classified as a restoration of the disturbed wetlands.
Answering questions from the Commission, Mr. Pawlak explained that plantings will be planted in the existing basin, as well as the proposed basin. The applicant has agreed to donate land for open space to the Town, which will have posted markers.
Commission members discussed the existing basin, feeling that some type of screening (shrubs) should be planted to ensure isolation.
It was suggested that roof runoff from the houses be placed back into the wetlands.
