10 Suggestions Given to Reduce Rahway River Runoff

The Rahway River Watershew Storm Water Mangement Conference in Millburn educated officials from townships affected by the river.

Storm water management experts proposed 10 regional practices to deal with water infiltration for the 24 municipalities affected by the Rahway River watershed, in Thursday evening's conference.

The watershed spans three counties — including Union.

Millburn Mayor Sandra Haimoff welcomed other township officials to the Millburn Library, saying they could prevent overflow of the Rahway River by working together.

The Rahway River Watershed Storm Water Management Conference educated township officials with presentations from Sandy Batty, executive director of the Association of New Jersey Enviromental Commission and Dr. Chris Obropta, Dr. Amy Rowe and Michel Bakacs from Rutgers. 

The Rutgers' presentations gave possible small steps townships could take to lower storm water runoff, such as rain gardens, green car washes, rain barrels or permeable pavements. These solutions have already been implemented in Clark and Maplewood with a $500,000 grant from the Department of Enviromental Protection.

Obropta discouraged larger solutions that could take 10 to 20 years to complete. He used a resevoir in South Mountain Reservation as an example, saying residents would need their congress persons to lobby for money to support it. 

The plan he suggested and simulated numbers would only need 25 percent of residents to participate in green technology solutions, but it could reduce runoff by 16 percent in a large storm. It would also only cost $38,000.

Batty's presentation detailed state regulations that townships should be following. "You can be stricter than state regulations," she encouraged.

Aftering presenting the 10 actions, a Cranford township official asked Obropta what is missing from the list.

Obropta responded, "What's really missing here is a plan. I think by having a plan, prioritizing and getting partners will help."

The recomended actions presented were:

  1. 10 percent reduction of runoff on municipal and school facilities by 2015.
  2. Mandatory training for planning and zoning boards members on storm water management regulations.
  3. Establish Rahway Tier Watershed Storm Water Adivsory Board to allow townships to attract grants from DEP.
  4. Amend ordinances on additions or any impervious sufaces added by homeowners that are 250 square-feet.
  5. Sponsor three demonstrations of green technology projects in the upstream of the Rahway River.
  6. Develop a program of best practices for public and planning and zoning boards.
  7. Distribute 5,000 rain barrels. Suggested to provide rebates instead of just giving away.
  8. Plant 10,000 trees outside floodway that will survive by 2016.
  9. Ask 10 largest property owners to adopt green technology to reduce runoff by 10 percent.
  10. Develop a regional open space program geared toward flood control.

I attended last night's session and can say that the explanation of things like pourous pavement, the use of swales and vegetative barriers and trees turned on many lights in the room about inexpensive alternatives to channeling storm water into the river. Cranford needs to prominently lead in this area because every step we can induce upstream towns to take benefits us as well. The Regional Mayor's Watershed Commission has led to the identification of substantial water detention opportunities in South Mountain Reservation and Lenape Park, more than we could have hoped for. Because of the sensitive nature of these sites we need to get out in front of the environmental issues by moving now to more seriously embrace green, "low hanging fruit" alternatives wherever feasible.
