The following calculators can be used to estimate the effect of reducing various environmental impacts at and along the waterfront

• Water Pollutants - can be significantly reduced or eliminated
• Energy Savings - from solar systems may cut utility bills by half.
• Water Containment - new systems can recycle over 90% of boat wash down areas.
• Green Buildings - can save 30-50% of primary energy, 40% of water, 70% of solid waste.
