Raise the Roof Campaign

One key structural result of the historic April 18, 2016 Tax-Day floods, was the loss of a wooden footbridge connecting Story Lake Garden to the rest of Mercer. Harris County Precinct 4 will replace the old bridge this summer, and we are raising money to build a roof over it to make it a true gateway to Storey Lake.
