As the Bahamas enters its extended rainy season, the Ministry of Works has ramped up proactive drainage maintenance efforts across flood-vulnerable zones of New Providence, while highlighting a host of structural and human-caused factors that are worsening recurrent flooding across the island.
Francis Clarke, a senior highway engineer overseeing the ministry’s road maintenance and construction division, outlined that his department pre-deploys work teams ahead of both the annual rainy season and Atlantic hurricane season to clear clogged drainage networks in areas with a long history of flooding. High-priority locations repeatedly targeted for these upkeep efforts include downtown Bay Street, York Street, and the residential community of Pinewood Gardens. Clarke emphasized that drain maintenance is a year-round priority for the department, rather than a seasonal reactive measure. Residents who encounter persistent flooding in their neighborhoods are encouraged to report issues via the department’s dedicated public hotline for rapid assessment.
For Pinewood Gardens, which faces frequent flood disruptions, the ministry has launched a data collection initiative to inform a long-term flood mitigation project. Ordered lift stations, a core component of the upgraded drainage system, have not yet cleared customs and arrived in the country. Under the project’s design-build contract, the lead contractor is currently gathering detailed hydrogeological data to finalize engineering blueprints. In the interim, maintenance crews continue regular cleaning and upkeep of existing drainage assets in Pinewood Gardens and adjacent flood-prone areas to reduce temporary flood risk.
Clarke also shared an update on ongoing infrastructure work in Coral Harbour, where sidewalk rehabilitation is progressing alongside drainage system upgrades. Like the lift stations for Pinewood Gardens, new mechanical pumps required for the Coral Harbour project are still awaiting shipment to the island. Clarke noted that Coral Harbour saw significant flooding during this year’s rainy season after private actors dumped two large loads of construction fill in natural drainage corridors, blocking water flow and forcing excess runoff onto surrounding roads and properties. While the project has faced minor delays, Clarke confirmed full construction will resume imminently. Once completed, the upgraded Coral Harbour drainage system will use mechanical pumps to move excess stormwater from detention ponds into the nearby canal, and a dedicated long-term maintenance program will be put in place to keep the pumps fully operational during storm events.
Beyond these two high-profile project sites, Clarke drew attention to systemic challenges facing New Providence’s entire flood management network. Many existing drainage lines were installed decades ago, he explained, and were never engineered to meet modern hydrological standards that account for increased urban development and shifting rainfall patterns linked to climate change. While the current network is sufficient to handle baseline runoff from public roadways, heavy storms frequently wash large volumes of debris into drains, causing clogs that reduce system capacity. Clarke partially attributed this debris buildup to uncovered trucks hauling construction aggregate and other materials from unpaved access roads to paved public corridors, with loose material spilling out onto roads to be washed into drains during downpours.
Unregulated private development is another major contributor to systemic flooding, Clarke stressed. Under the Bahamas’ Control Act, private property owners are required to manage stormwater runoff generated on their own land. However, many private commercial parking lots and new residential developments route their excess runoff directly onto public roadways, overloading the public drainage network that was only designed to handle runoff from the road right-of-way itself.
“Our public drainage infrastructure is sized to handle the exact footprint of the roadway. When additional runoff from private developed properties pours into the system, it pushes the network past its capacity, and that leads to widespread flooding,” Clarke said.
He added that the steady conversion of natural wetlands for new development has also eroded New Providence’s natural flood defenses, as wetlands act as natural sponges and provide unobstructed pathways for stormwater to drain from inland areas to the ocean. The combination of outdated infrastructure, unregulated private development runoff, wetland loss, and growing urban density continues to create persistent flood management challenges for the entire island of New Providence, he concluded.
