The Parkville Board of Aldermen on Tuesday voted to begin the process of fixing some of the damage caused from a flash flooding event on Wednesday, July 2.
The storm caused damage from the small stream, which starts at the Parkville Commons and travels south along Walnut and West Streets before meeting with Rush Creek and flowing into the Missouri River.
According to Jay Norco, city engineer, the storm that caused the flooding was well above even a 500-year storm event predicted for the Kansas City area. The storm caused seven inches of rain to fall in three hours.
The storm caused damage to a number of culverts under roadways and driveways as well as flooding in some homes and damage to property.
The city voted to approve an agreement for engineering services to replace the Elm Street and 11th Street culvert. The agreement is for no more than $9,300 in engineering services to design the new culvert and road with Harrington and Cortelyou.
According to Dan Koch, director of public works, the culvert sustained damage during the flash flood and will need to be replaced. He assured the board that the culvert was checked and though it sustained damage, the road above is usable.
Koch estimated the cost to replace the culvert might be between $100,000 and $150,000. Koch said that since the cost is not budgeted, the project would probably wait to be included in next year's budget.
The cost for the engineering services is not budgeted and therefore came out of the city's emergency fund.
The board also heard reports from several citizens who said they received damage to their properties in the flash flood.
Virginia Ground and Jim Horton both spoke to the board about damage to their properties.
Ground described a number of old trees along the creek, which had fallen into the creek and blamed recent construction upstream including a new housing development west of Bell Road.
Ground asked for the city to pay for the clean up of the trees in the creek and the other debris washed down by the flash flood.
Horton described the damage along his driveway and blamed it on undersized culverts, which block the flow of the stream under his and other driveways. He asked that the city replace the culvert to prevent the flood from happening again.
Koch told the board that the city usually does not replace culverts along private driveways that are not in the public right of way.
Norco said that the driveway was constructed before there were any guidelines for sizing of culverts to handle rainfall. The current driveway has one 48-inch culvert and Norco said today the driveway would be required to have three 48-inch culverts.
In other business, the board also received a credit for savings associated with the Brink Myers Road Improvements. The city is receiving a credit for $9,880.84 because some materials were purchased by the city instead of though the construction contract and because of landscaping done by neighboring property owners.
The board approved an increase in the limit to purchase waterline materials associated with the Brink-Myers Road Improvement project.
The increase raises the limit from $96,000 originally to a new cap of $101,000 because there were items the water district staff forgot to include in the original bill.
The city will now purchase additional isolation valves to place along the water line to keep from having to clean out the water line each time a new home or business is connected to the waterline.
