Frederick Street Stormwater Park Targets Rose Drive Flooding

A few inches of water separate dry homes from flooded ones near Rose Drive. Designers planned the new Frederick Street Stormwater Park, on 3.9 acres between First Street and Pine Street, to catch that water before it gets there. Once the money to build it is in place, crews could start work within a few months.

When the City applied to the state for help paying for this park, it called the neighborhood around Rose Drive “one of the more critical areas in the city.” In that application, the City wrote that residents there “deal with flooding on a regular basis” and that “Flood waters enter their homes causing damage to property.”

How Frederick Street Stormwater Park will work

The heart of the park will be a shallow, planted basin fed by the ditches along the surrounding streets. Stormwater spreads out across it and soaks into the ground, and the native plants the designers chose draw it up through their roots and pull nutrients out of it. When a storm brings more water than the park can hold, the rest flows on into the City’s existing storm drains, the way it does now.

As drawn now, the park would hold about 252,000 cubic feet of water, and the designers’ goal for the final plan is 364,000 cubic feet, about 2.7 million gallons. Margo Posten and Dennis McGrury, with the Grand Bay National Estuarine Research Reserve’s Coastal Training Program, lead the project, and Posten said ponding “will be limited and temporary and occur primarily during rain events and brief periods after a storm event.” She said the park, like a rain garden, is meant to drain within about 72 hours.

What it could mean for Rose Drive

Posten described what the park could mean for the families downstream.

“It is my hope that the stormwater park will capture surface water that typically flows into the Rose Drive neighborhood in order to provide some relief to that community. If it can collect 2 to 4 inches, as has been modeled, I think the residents will see an impact and hopefully a reduction in the frequency of flooding. Just a few inches can be the difference in homes being flooded.”

The soil and plants in the park also filter sediment and pollution out of the water that soaks in, so less of it reaches the Escatawpa River, where the area’s ditches and storm drains empty by way of Rhodes Bayou. Posten said that cleaner water will mean better habitat for the wildlife that lives in and along the river.

When work could start

The City of Moss Point has already purchased the land, and the designers have carried the plans 30 percent of the way to a final, buildable design. They will finish the plans in the next phase, once the money comes in, and Posten said when work can start “will depend on when the funding is received.” Once the money is in place, she said, “it will take just a few months to actually get started.”

The walking path, the lighting and the benches are in the budget and in the design. Playground equipment is the one piece the park’s funding cannot buy, and the project team is looking for another way to pay for it.

A park the neighbors helped design

Neighbors have shaped this park from the start, through a community advisory committee whose input, Posten said, helped create the current design. According to the project’s page on River City Flood Ready, residents asked for an accessible, safe walking path where older neighbors could get their exercise. They also wanted to see clear across the park, so the designers chose pond cypress and slash pine and left out the shrubs that block the view.

In the drawing, you can also see flowering meadows of native plants, a nature play area, an open lawn and parking along First Street, and the designers favored native meadow and evergreen trees so the park needs as little upkeep as possible. Posten said the team plans community meetings in the next phase and wants anyone who would like to help with the planting to join in. “This is their park and we want them to take ownership of it and to be involved,” she said.

A year of results from Kreole Elementary

You can already see this approach at work at Kreole Elementary School, where the Grand Bay reserve’s rain gardens and bioswale, a planted channel, catch runoff from nearby roads. McGrury and Jessica Woodall, also of the Coastal Training Program, have been monitoring sensors that log rain, water levels, soil moisture and water quality every 15 minutes since May 2025, and through July 2026 the system captured 80 storms and about 71 inches of rain. After a typical storm, the bioswale drained in about three and a half hours, and on May 28, 2026, when 4.8 inches of rain fell, it filled and drained the same day.

The water the bioswale held was also far cleaner than the water in the enclosed storm drains it connects to, with a small fraction of their dissolved solids. It carried about 6.7 milligrams of oxygen per liter, a healthy level for aquatic life, while the drains held almost none. Posten said early readings also point to the gardens removing nutrients, and her team hopes to share more results soon.
