There are in excess of 700 trees on the 178acres. Acombinationoftheseveredroughtexperiencedin HoustonintheSummerof2011andtheinoperableirrigation system resulted in some tree loss. The proposed project improvements,oncecompleted,maypreserveupto42%of the existing mature and native trees especially along the outer edges.
