Ravenwood Park Neighborhood Stormwater Improvement Project Study

Project Number: SD-000032-087

Project Update: October 1, 2024

The project is in the study phase. Model calibration has been completed and existing conditions modeling is underway.

A NSIPS Community Kickoff Meeting was held on July 1, 2024. The meeting slides have been uploaded to this page. 


Project Background

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.

Project Description

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:

  1. 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.
     

  2. 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.
     

  3. 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.
     

  4. 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.

Project Location

The study area encompasses the Ravenwood Park neighborhood and surrounding areas.

Project Phase

The project is in the study phase. Model calibration has been completed and existing conditions modeling is underway.

Timeline

The study is scheduled to be completed in Summer 2025.

What to Expect

No field work is anticipated at this time.

Project Cost and Funding Source

The Ravenwood Park Neighborhood Stormwater Improvement Project Study is funded for $330,000. Funding for implementation of solutions is dependent upon future budget availability and allocations. Stormwater projects are funded through the county Stormwater Service District.

Presentation to the Community

As the project advances through the modeling phases, community meetings will be scheduled to update neighborhood residents on the study progress and share findings. Meetings will be scheduled upon completion of existing conditions modeling, strategic stormwater management solution development, and overall study completion.
