Description of Proposed Action

The Project Sponsor, Holochuck Homes, LLC, proposes the construction of the Holochuck Homes Subdivision on a 111 acre project site which is located between Trumansburg Road (NYS Route 96) and Taughannock Boulevard (NYS Route 89) on the westerly slopes of Cayuga Lake.  The proposed development includes the construction of a cluster development of town houses consisting of 21 buildings, ranging from 2 to 6 single family units each.  A total of 106 privately owned, single-family, town house units are proposed.  The residential development will be concentrated on the west side of the property along Trumansburg Road.  The town house development will include the requisite residential roads, utilities, driveways and storm water management facilities. Upon completion, the development will include approximately 3,900 feet of roadways and associated public utility infrastructure dedicated to the Town of Ithaca.  The storm water detention facilities will be maintained by a Homeowners Association.

Approximately 75 acres occupying the eastern portion of the property consists of steeply sloping and forested terrain which will remain undeveloped.  This undeveloped portion of the property will be conveyed to the New York State Office of Parks, Recreation and Historic Preservation with the understanding that it will be maintained as undeveloped park land with pedestrian and hiking trails.  

Potential Significant Environmental Impacts

On December 18, 2007, The Town of Ithaca Planning Board as Lead Agency determined that the proposed action may have a significant impact on the environment and issued a Positive Declaration and Notice of Intent (NOI) to Prepare a Draft Environmental Impact Statement (DEIS).  As described in the Attachment to the Positive Declaration Form and NOI the proposed action may have potential significant impacts on the following:

1.       Physical Change to Project Site relating to construction on slopes in excess of 10 percent, disturbance of highly erodable soils, and physical disturbance of approximately 26 acres of undeveloped land that will continue for more than one year and may involve more than one phase or stage.

2.       Non-protected Body of Water relating to the potential disturbance of numerous intermittent steams which traverse the project site.

3.       Water Resources, Drainage and Surface Water Runoff relating to the creation of potable water demand in excess of 20,000 gallons per day and to potential storm water runoff impacts during and after construction.

4.       Wildlife and plants associated with the removal of approximately 26 acres of forest and meadows that serve as habitat for local wildlife and which may also contain important or locally scarce plant species.

5.       Aesthetic Resources relating to changes in the visual landscape as seen from Trumansburg Road and the shores of Cayuga Lake.

6.       Historic and Archeological Resources concerning proximity of nearby buildings that may be eligible for listing on the State and National Registers of Historic Places, and also concerning potential impacts on an area designated by the New York State Office of Parks and Historic Preservation  as sensitive  for archeological sites on the New York State Inventory. 

7.       Transportation relating to proximity of proposed access roads to existing intersections, impacts on the level of service of existing roads and intersections, implications for mass transit service (bus stop), need for highway modifications and traffic control devices, need for bicycle and pedestrian trails and linkages.

8.       Noise relating to potential construction related noise impacts to surrounding areas.

9.       Community Character relating to an increase in development density which will create additional demand for community services.

DEIS Format and Contents

The format and content of the DEIS for this project will be prepared in accordance with the provisions of 6 NYCRR 617.9(b).  The DEIS will assemble relevant and material facts, analyze significant adverse impacts and evaluate reasonable alternatives.  The DEIS will be clearly and concisely written in plain English that can be understood by the general public.  The DEIS will address the specific impact categories that have been identified through the Scoping Process. Detailed technical studies will be performed as necessary to identify and analyze the potentially significant environmental impacts.  These technical studies will be summarized and referenced in the body of the DEIS and also included as an Appendix to the document.

Narrative discussions will incorporate graphic illustrations such as tables, charts, and maps to describe the project, its location, the affected environment, potential impacts and mitigation measures.  Qualitative discussions will be supplemented with quantitative data where appropriate to thoroughly identify, describe and evaluate potential environmental impacts.  Full scale site and subdivision plans will accompany the DEIS as an appendix, with pertinent and appropriate drawings and figures reduced and incorporated into the body of the DEIS.

Following is the Project Sponsor’s proposed DEIS format and content to address all of the potential significant environmental impacts that have been identified through the scoping process.

III.               ENVIRONMENTAL SETTING, IMPACTS AND MITIGATION

This section will be structured to describe each component of the environment where potential impacts have been identified, describe the nature and magnitude of anticipated impacts at a level of detail that reflects the severity of the impacts and the reasonable likelihood of their occurrence, and the proposed mitigation measures to reduce these impacts as specifically detailed below. 

A.         Project Site

The proposed development will result in a physical change to the project site and will occur in areas with slopes as great as 15 percent and may involve disturbance of areas with highly erodable soils.  Construction activities may occur for more than one year and may involve multiple phases.  As such, appropriate interim and permanent measures will be taken to stabilize the impacted portions of the project site during, between and following periods of active construction. In order to properly address these concerns this section will include a discussion of the topography and soils of the project site, identify potential impacts and describe propose mitigation measures to reduce impacts.
