Description
Park areas, parking lots and road beds (to the top of the curb), and other open spaces used as temporary storage areas during large rain events to reduce downstream damage
Strengths
Existing facilities and open space can be readily modified to serve multiple uses (e.g., transportation or recreation) as well as stormwater management, without a significant increase in the capital, operational and management costs of the facility or park.
Weaknesses
The facility's or park's primary functions (transportation, parking, recreation) can be impaired during and immediately after a storm event. Residents may not desire the temporary flooding of the park or facility while it is serving a stormwater storage function.
