Highland Park, New Jersey, is a charming borough nestled between New Brunswick and Edison, offering a mix of urban and suburban landscapes. However, like many communities in the state, it is not immune to the risks of flooding, particularly during heavy rainfalls or storms. For residents and property owners, mitigating the risks of flooding is crucial to protect homes, infrastructure, and the overall quality of life.

When it comes to flood mitigation in Highland Park, there are many strategies available. Yet, the single best strategy to reduce flooding risks and minimize damage is the implementation of Green Infrastructure (GI).



Why Green Infrastructure?


Green infrastructure refers to natural or semi-natural systems that manage stormwater and help absorb rainfall before it has the chance to cause flooding or run off into streets, sewers, and waterways. Unlike traditional, hard infrastructure solutions (like large stormwater pipes or concrete barriers), green infrastructure uses natural processes to reduce flooding while providing environmental, social, and economic benefits.

For Highland Park, with its mix of urban development and green spaces, green infrastructure presents an ideal solution. It can be customized to fit the borough’s unique needs and landscape.

What Are the Key Components of Green Infrastructure?


Green infrastructure can take many forms, but the most effective strategies for flooding mitigation in Highland Park include:

1. Rain Gardens and Bioswales


Rain gardens and bioswales are shallow, vegetated depressions that allow rainwater to soak into the ground rather than run off into storm drains. These systems help reduce runoff, improve water quality, and prevent flooding in neighborhoods. Highland Park’s residential areas, particularly those near the Raritan River or other flood-prone areas, could greatly benefit from the installation of these systems.

  • How it works: Rainwater is collected in the garden or bioswale, where it slowly infiltrates the soil. This reduces the volume of water that would otherwise enter stormwater drains or flood low-lying areas.

  • Benefits: They are low-maintenance, aesthetically pleasing, and can even support native plants, which help improve local biodiversity.


2. Permeable Pavement


In urban areas like Highland Park, a significant amount of surface area is covered with impermeable surfaces like concrete, asphalt, and rooftops. These materials prevent water from soaking into the ground, contributing to stormwater runoff and increasing flood risks. Installing permeable pavement—whether on driveways, parking lots, or walkways—allows water to pass through the surface and seep into the soil below.

  • How it works: Permeable surfaces are designed with gaps or porous materials, allowing rainwater to be absorbed rather than flowing into drainage systems.

  • Benefits: This solution reduces runoff, helps recharge groundwater, and can prevent localized flooding during storms.


3. Green Roofs


Green roofs—rooftop gardens—are an increasingly popular option for managing stormwater in urban settings. They absorb rainwater, provide insulation for buildings, and can be a part of Highland Park’s broader flood mitigation strategy, especially for commercial buildings or apartment complexes with flat roofs.

  • How it works: Green roofs consist of vegetation planted over a waterproof membrane. These plants help capture rainwater, slowing its release and promoting evaporation.

  • Benefits: Green roofs reduce the strain on the local stormwater system, contribute to energy savings, and enhance the aesthetic value of buildings.


4. Urban Wetlands and Riparian Buffers


Highland Park is located near the Raritan River, and urban wetlands or riparian buffers along the riverbanks can serve as valuable flood mitigation tools. These natural areas help absorb excess rainwater and protect against erosion. By creating or restoring wetlands, the community can improve water quality while preventing flooding during heavy rainfall.

  • How it works: Wetlands absorb large amounts of water, while riparian buffers—vegetated areas along rivers and streams—reduce runoff and filter pollutants.

  • Benefits: These systems can help to manage large volumes of water, reduce flood risk, and enhance biodiversity.


5. Tree Canopy Expansion


Trees play a crucial role in flood mitigation by slowing down rainfall, absorbing water, and reducing stormwater runoff. Highland Park’s urban forest and street tree canopy can be expanded to provide more natural water management.

  • How it works: Trees intercept rainwater with their leaves, slowing the rate at which it hits the ground and allowing it to infiltrate into the soil. Their roots also help absorb excess water.

  • Benefits: Expanding tree canopy reduces the volume of stormwater runoff, lowers urban heat islands, and beautifies the community.


Why This Strategy Works for Highland Park



  1. Cost-Effectiveness: Green infrastructure can be more affordable than traditional stormwater management systems like tunnels or dams. While initial implementation may require some investment, the long-term benefits—such as reduced flooding, improved property values, and lower maintenance costs—make it a wise choice for communities like Highland Park.

  2. Environmental Benefits: Green infrastructure reduces the "urban heat island" effect, improves air quality, and provides habitat for wildlife. Additionally, it can help filter pollutants from stormwater before they enter local water sources like the Raritan River.

  3. Community Well-being: Beyond flood mitigation, green infrastructure solutions—such as parks, green roofs, and street trees—create spaces for recreation, promote mental health, and increase the overall livability of Highland Park. Green spaces make the community more resilient to climate change and can also foster stronger social connections.

  4. Scalability and Flexibility: Green infrastructure can be implemented at various scales, from small residential rain gardens to large public park systems. This makes it highly adaptable to different areas of Highland Park, whether in dense urban zones or more suburban areas.


Implementing Green Infrastructure in Highland Park


For Highland Park to fully benefit from green infrastructure, local government, businesses, and residents must work together. The borough’s planning departments can support green infrastructure initiatives by updating zoning laws and offering incentives for businesses and homeowners to adopt sustainable stormwater solutions.

Additionally, public outreach campaigns and education programs can raise awareness about the importance of managing stormwater and encourage individual action. Homeowners and property developers can also contribute by incorporating green infrastructure into their building projects.

Conclusion


Flooding in Highland Park, NJ, is a real concern, but it’s a challenge that can be managed with smart, sustainable solutions. The single best strategy for flooding mitigation in the borough is the implementation of green infrastructure. By embracing natural systems like rain gardens, permeable pavements, green roofs, and urban wetlands, Highland Park can reduce flood risks, enhance its natural environment, and create a more resilient community.

By acting now, residents and officials in Highland Park can build a future where floodwaters no longer pose a serious threat to the community’s safety, economy, and quality of life.
