• Units will share gardens where people can grow their own produce.

• Solar panels for electricity and heating water.

• Permeable pavers to let water seep into the ground (so it doesn't run into the nearby St. Croix River).

• Energy-efficient Andersen windows.

• Electric car photovoltaic recharging station at a community center.

• Rainwater will be used for community gardens and for the geothermal loop fields.
