Engineering Review

The Engineering Division reviews proposed development plans to ensure that stormwater is managed according to code requirements, both during and following construction. The Engineers promote "best management practices" (BMPs) that manage stormwater for both water quality and quantity.

From the earliest stages of site design, stormwater management must be a key consideration. By identifying those parts of the site best suited for dealing with stormwater in a natural way, Conservation Design elements can be applied. This is the first step to "Green" site management and to intelligent sustainable development.
