|Home Building and the Chesapeake Bay|
The Home Builders Association of Maryland has developed a pocket card on behalf of the home builder associations in Maryland for members' reference when discussing the health of the Chesapeake Bay.
As you can see from the following data, residential construction does, indeed, have an impact on water quality in the Chesapeake Bay and its tributaries. However, any reasonable person can also see that its impact, while not insignificant, plays a very minimal role in contributing pollutants to our water bodies.
For copies of the card, please contact HBAM at 410-265-7400 or email Kristin Hogle.
