6 options explored by Clarendon Hills in the event of future flooding
CLARENDON HILLS – A year after the 2013 spring storms and subsequent floods struck the community and its residents, the Clarendon Hills Village Board, administration and staff continue to explore various concepts to alleviate any future flooding that could occur.
The following six plans cover the details, cost and timetable of each preventative measure discussed by the village.
1.) Local property acquisition
What: The Village of Clarendon Hills suggested purchasing and re-purposing privately owned properties that are most susceptible to flooding.
Cost: Varies, but tends to be expensive because of the home values in Clarendon Hills.
Status: This option was determined not to be cost effective; also, officials found that no properties would be eligible for federal funding, according to the village.
2.) Storm water ordinance
What: The Village of Clarendon Hills would strengthen the existing storm water standards in place.
Cost: Engineering and development is estimated at $3,800.
Status: A new storm water ordinance will be discussed later in the spring.
3.) Upgrade pumping station at Chestnut Alley
What: Under this concept, the village would pay for upgrades to the pumping station located at Chestnut Alley.
Cost: About $350,000
Status: This plan was determined not to be cost effective given the “small benefit” for the slated costs, according to the village.
4.) Creation of additional storm water detention
What: The village would explore the creation, or the improvement of, storm water detention facilities, of which several options were explored.
• $19 million – underground water storage facility at Park Avenue
• $5 million – major Hosek Park detention expansion
• $1.3 million – minor Hosek Park detention expansion
• $11.3 million – Dallas Street detention basin improvements
• $8 million – Metra lot underground stormwater basin
Status: None of the proposed upgrades were determined to be cost effective at this time.
5.) Monthly storm water fee
What: A fee would be introduced as a monthly charge on resident water bills to fund storm water improvements.
Cost: Varies, and would depend on the annual projects completed.
Status: The Village Board chose not to move forward with the fee.
6.) Deep root detention pond plantings
What: Plantings in the village detention ponds would allow the spaces to hold more water in the event of future flooding.
Status: The public works department is continuing to explore this option.
More updates on all projects will be made available from the village in the coming months.
