Streetlight Outages

The following streetlights are out of order due to failed underground wiring:
1) East side of Lexington West, behind 6638 Lexington South
2) East side of Regent, across from 50011 Regent
3) Northwest corner of Watling and Lexington South
4) Southwest corner of Watling and Lexington North

Some of these failures are due to the underground wiring being cut by construction crews back in 2004-2010.  They were repaired with splices which over time became corroded by moisture, which then caused them to eventually short out. Other failures might be the result of more recent construction activity.

The underground electrical lines for the streetlights do not appear on the MISSDIG drawings, so the contractors are not responsible for the damage.  Therefore, it is up to the Association to repair and replace the failed underground wiring.  Since it is very difficult to find the location of the break, a new underground line must be installed between the streetlight and the electrical meter, which can be anywhere from 100 to 500 feet away. The Board of Directors will have new wiring installed for each streetlight once the risk of damage from new construction in the vicinity has subsided.

Storm Sewer Repairs

The heavy rains we had on August 11, 2014 (post with photos) caused two sinkholes to develop on our property.  The sinkholes resulted from breaks in the underground storm sewer pipe that had gone undetected until then.

What happened that day is that the retention basin filled up from the 5.1 inches of rain we received that day, causing the water to back up into the storm sewers and catch basins.  By 9:00 p.m. some streets were covered from curb to curb with standing water that had no place to go until the retention basin eventually drained down later that night.  In the meantime, the backed-up storm water escaped from the breaks in the two buried pipes and as the water receded, it sucked the surrounding sand into the pipe, causing a small sinkhole behind 49995-50011 Regent and a much larger sinkhole between 49992-50008 Watling.

The Association hired a contractor who managed to get the storm sewer pipe at the smaller sinkhole repaired later in the fall of 2014.  However they found that the pipe at the larger sinkhole was much deeper and after an initial attempt had to be abandoned, they brought in heavy equipment last week to make the repairs.

In both cases, it's believed that the breaks in the plastic storm sewer pipe were caused by construction debris that was dropped directly onto the pipe during the backfilling of the storm sewer trench in 2004.

Landscaping repairs at the smaller sinkhole have already been made and the Board of Directors intends to have the landscaping repaired at the Watling sinkhole sometime after Labor Day.

Below are photos of the Watling sinkhole repairs that were made on Aug. 13, 2015.

The excavator had to dig a hole about 7 ft. deep and 12 ft. wide to expose and repair the broken storm sewer pipe.

The worker's foot is next to the break in the storm sewer pipe.

The broken section was cut out and replaced with a new section of 12 in. diameter pipe.

Roadway Maintenance

Workers finished the last of the asphalt paving at
around 10:30 a.m. on Aug. 4th.

The Association's Board of Directors recently contracted to have two catch basins rebuilt and approximately 220 feet of access drive replaced in front of 6915-6979 North Central Park.  This work took place over the past two weeks and was completed today. 

The asphalt needs to harden for three days before it will be safe to drive upon. In the meantime, affected residents may park along the north side of the North Central Park roadway.
