The surrounding lawn area at Hamilton Park was replaced with bio swales and grass areas to reduce the City’s water usage and improve stormwater management. Bio swales are designed to collect rainwater, soak it in the ground and filter out any pollution. The bio swales installed are a type of groundcover that suppresses weeds and grows low to the ground floor. Bioswales are a great tool for stormwater management because they improve rainwater quality and reduce runoff. Native bioswale species are adapted to being dormant outside of the rainy season and can survive until rainwater is available again.
