Boswell was retained by the County of Passaic to provide engineering design, permitting, surveying, and construction management services for the rehabilitation of an existing duck pond and a 2-mile stretch of the Goffle Brook flowing through Goffle Brook Park in Hawthorne, New Jersey.

The banks of Goffle Brook displayed evidence of progressive erosion at numerous locations along the study area. Additionally, the brook’s flow had eroded the banks and exposed the root system of existing vegetation. Moreover, an on-stream duck pond was exhibiting degradation and ectophization due to siltation/sedimentation combined with an overabundance of resident waterfowl. Boswell worked closely with the NJDEP in terms of permitting and bioengineering. Due to the project’s size and scope the State required a Freshwater Wetland Individual Permit rather than a common general permit. Lastly, Boswell designed bioengineering bank stabilization methods to include:
• Live stakings
• Vegetated geogrid
• Vegetated gabion baskets
