Lakewood Lake #1 & #2 Update
Dam safety inspections by AR Natural Resources Commission completed in 2015 found the need for repairs to both Lakewood dams #1 and #2 in order to meet the Dam Safety requirements for high-hazard dams.
Over many years of aging, dams #1 and #2 have served their purpose well but are in need of immediate repairs. Both dams are leaking. The slope of the dams are entirely too steep and we are hauling in proper material to meet the 3-to-1 slope required by AR Natural Resources, City Engineers and other dam consultants. The trees on both sides of the dams are also a problem. The tree roots extend deep into the ground under the dams. The roots provide an avenue for water to flow through the dams. As trees die, especially on the front side of the dams, they leave a void, allowing water to accumulate, erode and break down the integrity of the dams.
It took several months in the pre-planning stages of the project for engineers and other specialists to determine the extent of damage and design a plan for repair. Core drilling and sampling was performed to help determine the depth and extent of damage to the dams. Surveying and clearing the dams was also performed in order to better determine the extent of repair. We had to install a new drain system for Lake #1 in order to drain and remove standing water off of the toe of the dam. We added extra drains for adequate draining on Lake #1. Drains were extended for dam #2.
Our dams provide many benefits to Lakewood residents and visitors. The most important benefit is serving as a water reservoir for everyone from the toe of dam #1 all the way to the Arkansas River. Without our dams, areas and homes below Lake #1 dam could experience flooding from excessive rain. Our dams support Natural wildlife which include ducks, geese, and fish which are managed by marine biologists and other specialists. There is much more to our lakes than their natural beauty.
The LRID Board approved the dam rebuilding projects in order to maintain the highest level of safety to residents and visitors to North Little Rock.
Once the testing and clearing phase was complete, the planning phase to rebuild the dams began.
Finding proper materials for both dams was a very difficult task. At our contractors recommendation, we dug material out of the upper end of lake #1 and hauled it to both dams for dirt work. This material was compacted to proper specifications in order to meet the engineering guidelines. Using material from the upper end of lake #1 will make the upper end much deeper, will reduce shallow stagnant water and save us substantial costs in hauling in compactable materials for the dams.
Both renovation projects will total an estimated $732,209.65. We would like to thank the City of North Little Rock for partnering with us for $100,000.00 on dam #1 and $138,000.00 on dam #2.
We are very pleased with the quality of work that our contractor, SITEWORKONE, has provided. We have recently had an inspection by AR Natural Resources Commission and both dams passed their inspections.
We anticipate completing our dam projects soon. We appreciate your patience during our dam restoration process. Please call Ken Sullivan at LPOA for additional details or questions at (501) 753-4937.
