Project Details: Two hundred and twenty-one condominium homes, driveways, streets, parking areas, sidewalks, a recreational area, a pool, a commercial area, and a community center are part of the Lake Point project. The site’s topography included a ridge line which divided the site into east and west portions. Stormwater treatment for pollution control was being managed by local bio filtration areas. StormTrap vaults were utilized to address flow control (hydromodification) and peak flow attenuation prior to discharging flows from the site.
Challenge: The challenges for this site was the minimal amount of available open space to place a water storage unit as well as vertical constraints of being able to tie into the existing downstream storm drain system.
Solution: Stormtrap DoubleTrap was chosen due to it being the most efficient design in both cost and area impacted. A rectangular basin was installed in the east side of the site and a triangular vault was installed in the west. Stormtrap met the volume capacities and site`s requirements, fitting in a non-rectangular-shaped storage footprint.
“Back and forth coordination with StormTrap has evolved into a productive and efficient working relationship stemming from this project” Alisa Vialpando, Consulting Engineer for Hunsaker & Associates.
