Immediately adjacent to Wesley School lies an existing stormwater management system owned and maintained by the Village of Addison.  The system includes both overland and subsurface drainage improvements that convey stormwater from residential areas to the west.  This system then continues to through the school grounds to and ultimately to the Salt Creek.  The existing system was not functioning as intended and the school grounds were subject to frequent flood and standing water.   Trotter was retained by Village of Addison to evaluate the existing area and then design and perform construction engineering related duties for the proposed improvements.

Field inspections with the Village of Addison Public Works Department revealed that the existing stormwater management system was surcharging due to the collection sediment and construction debris.  Although this was able to reduce the frequency of overland flooding, the existing ditch was still a maintenance issue for the Village.  Trotter and Associates recommended the installation of a low maintenance vegetative swale.  This swale eliminated the existing over grown grass channel that continuously held water, and provided the Village with properly designed vegetated swale.  This low maintenance best management practice, coupled with rounded river stone, filters overland flow.

In order to not interrupt school activities the project was scheduled during the summer months, with all work completed prior the start of fall sessions.  The project was completed more than 40% under the allocated budget.
