Engineering

The majority of ponds and greenways are mowed on a cycle of two times a year, to once every other year as needed. The purpose of mowing stormwater land is not to maintain these areas as turf (as City Parks are mowed), but to maintain access, cut back woody plant growth or promote desirable vegetation. Engineering strives to balance the need to mow with wildlife, recreational and aesthetic uses of the land.

Woody plants, trees and shrubs, if not planted in an appropriate spot on ponds and greenways, can shade out ground-layer plants and open soil up to erosion. 

Tree roots can damage stormwater pipes, and prevent access by Engineering vehicles and equipment to stormwater infrastructure.

Sometimes, poorly-functioning greenways and ponds need to be reconstructed or updated. During reconstruction, it may be necessary to remove trees in order to regrade the land or allow access to vehicles and equipment. Wherever possible, construction is done without disturbing high-quality trees like oaks, hickories, and other hardwoods.
