Connecting the Past with the Future

Repurposing Hoffman House, Reynolds House & Upper Landing for the 21st Century

Upper Landing is a link between the historic Dutch presence in the Hoffman House and modern Dutch Design of the laminated timber Bridge-Over-the-Falkill; and can become a link between Historical Industrial Activities and Sustainable Power Generation in the Fallkill; and between Young People's Education at the Children's Museum and Adult Education in Restoration Technologies at the Reynolds Eco-Innovation Center.

Upper Landing gives the City of Poughkeepsie a unique opportunity to participate in the increased tourism generatd by the Walkway Over the Hudson by providing facilities for bicycle rental, gifts and refreshments.

The Upper Landing Committee intends to work with local educational organizations such as Marist College, Vassar College and Dutchess Community College to plan exhibits and activities to highlight the area's industrial history, its early Dutch Roots, and the ecological significance of the Fallkill Creek and the Hudson River Estuary.

The Dutch designed laminated timber Bridge-Over-the-Fallkill will become a tourst destination in its own right with a viewing platform for observing activities on the Hudson and the Fallkill.

Solid Waste

Solid Waste Disposal Heirarchy
Heirarchy of Materials Management

20 years ago the New York State Legislature created the Resource Recovery Agencies throughout the Mid-Hudson Region.

These agencies have built and operated transfer stations, recycling facilities, a waste-to-energy plant and established hazardous waste disposal programs.

Counties must now submit acceptable Solid Waste Management Plans for their next 20 years of operation.

The DEC is requiring counties to increase their ability to reduce, reuse and recycle its waste following a plan called BEYOND WASTE.

It is time for local counties to take advantage of a recent Supreme Court ruling that gives them more control over the waste generated within County boundaries.

Preserving the Past

Waterlands Monitoring Plan
Waterlands Monitoring Plan

Each piece of property is unique. The parcel was half working farm, half forest. The owner wanted to preserve the farm as a going concern that could be operated by the Home Owner's Association. Building homes and septic systems in the woods would have destroyed the forest. Therefore, a small wastewater treatment facility was designed to serve the clustered subdivision. Extensive buffers were provided for the Federal Wetlands located on the property and each lot was carefully designed to preserve existing mature trees.

Anticipating the Future

Turtle Culvert
Turtle Culvert

Abundant wildlife congregating around wetlands and vernal pools are an asset to be featured, not feared. If migration paths from summer nesting to winter mud hibernating intersect with roads or driveways, culverts designed as wildlife corridors can be provided to enable humans and amphibians to co-exist.
