Public Works and Environmental Services Alert:
The Ravenwood Park neighborhood was developed in the 1950s-60s, before the establishment of modern stormwater management regulations, making it subject to drainage issues. Residences in the neighborhood have experienced recurring flooding in recent years. Stormwater management in the neighborhood is subject to potential impacts from climate change and ongoing redevelopment. The study was initiated by the County to analyze these challenges.
The study will utilize PCSWMM one-dimensional and two-dimensional integrated modeling to simulate conditions in the watershed. Various scenarios will be modeled in order to gain a thorough understanding of the stormwater management challenges facing the community.
Goals of the study include:
Analyze existing conditions.
A variety of storm intensities will be modeled to assess their impact on existing stormwater management in the neighborhood. A sensitivity analysis will be performed to determine the least intense design storm that causes structural flooding for all residences in the study area.
Assess potential development impacts.
A pending development scenario will be modeled, incorporating any planned developments in the neighborhood. A maximum potential development scenario will also be modeled.
Assess the impacts of climate change.
The study seeks to understand the impact of projected precipitation increases on stormwater management in the neighborhood. All existing and future condition model scenarios will be run with both current and climate-change adjusted rainfall.
Identify strategic stormwater management solutions to mitigate flooding.
The study will produce a conceptual suite of potential solutions based on model results of both existing and projected future conditions.
The study area encompasses the Ravenwood Park neighborhood and surrounding areas.
The project is in the study phase. Model calibration and existing conditions modeling have been completed. Pending and maximum potential development modeling are underway.
