Walnut Hill Park Drainage Improvements
New Britain, Connecticut
Walnut Hill Park encompasses over 85 acres and is designated as a Historic District on the National Register of Historic Places. The park is an Olmsted design and it is required that all improvements be developed with sensitivity to the park design, history, character and uses.
As part of this project, any proposed changes to Walnut Hill Park were reviewed for consistency with the National Registry to ensure that any historical resources were being preserved.
BETA was selected to provide site/civil design services to correct severe drainage problems in Walnut Hill Park located in the City of New Britain. The existing drainage system serving the park was undersized and had several areas where storm drainage piping had collapsed. This caused the existing recreational fields to be wet and unusable for a significant number of days during the year. In addition, the downstream drainage system outside of the park area was not sufficient to accept stormwater runoff from the park.
The City also requested that the existing recreational facilities be expanded and brought up to current design standards to meet the needs of the present demands on these facilities.
The scope of work included a hydrologic/hydraulic analysis of various areas within the park and three off site drainage systems including proposed improvements, drainage improvements along the eastern property line to eliminate impacts to private property owners, layout, grading and drainage improvements in the playing field area including the addition of a soccer field, drainage improvements near the maintenance garage and design of a storm water detention system north of Hart Street to stormwater flow to the existing downstream drainage systems. Also, irrigation was provided for all of the proposed facilities.
BETA was also retained to provide construction administration services during the construction of the project.
