Westchester County Executive Rob Astorino has sent down a bond act to pay for the restoration of more than three acres of wetlands and river banks to help ameliorate the flooding problem on the Bronx River in Greenburgh, he announced today.
The work would be done north of Fisher Lane and east of the Bronx River Parkway. It is one of seven planned flooding projects along the river and the Sound Shore estimated to cost $9 million.
“It is important that we target achievable projects in problem areas in order to reduce and prevent future flooding,” Astorino said in a statement. “The causes of flooding in this county are a result of many complex factors that cannot be fixed overnight or without significant capital investments beyond the means of the county. But the county can and must continue to do whatever it can on its own to address this problem.”
The project includes removing invasive plants, replacing culverts, regrading and stabilizing the river banks and planting native vegetation.

The county statement describes the other projects:
Last year, four of the seven capital projects targeted by the Astorino administration for funding were along the Bronx River. The three other Bronx River projects include:
• Mount Vernon/Yonkers: Oak Street pump station rehabilitation. Cost estimate $450,000 to $500,000; construction is underway and will be completed by late summer/early fall.
• Yonkers/Eastchester/Scarsdale: Bronx River channel re-alignment and bank stabilization at Garth Woods. Cost estimate $1 million; design to commence later this year.
• Eastchester/Yonkers: Harney Road vicinity stream bank stabilization and channel modification. Cost estimate to be determined; design to commence later this year.
Two additional projects were identified by local municipalities as priority flood-mitigation projects and were proposed to the county for implementation with a local commitment to fund at least 50 percent of the total cost. The county will fund the balance. They are:
• Larchmont: Drainage improvements along Pine Brook at the Boston Post Road (Route 1) crossing. Cost estimate to county $2.3 million; awaiting a revised cost estimate from village.
• New Rochelle: Hutchinson River culvert replacement. Cost estimate to county $2.5 million; awaiting word from the city as to how and when they want to proceed on design as well as the municipalities that will participate (Scarsdale and Eastchester).
Lastly, the county proposed the replacement of a sewer line on Anita Lane in Mamaroneck. The removal of the center support structure currently in the river will contribute to flood mitigation. Cost estimate is $2 million; design is expected to begin in the third quarter of 2013.
