STAFF REPORT TO:Mayor Keis and Members of the City Council FROM:Bill Dircks, Public Works Director DATE:September 9, 2020 RE:Veterans Memorial Park Upgrades ACTION TO BE CONSIDERED: Motion to approve the installation of polymeric sand between the pavers at the park along with the repair of a section of pavers by Southview Design in the amount of $6,695.97 as well as approving funds for refurbishing the bubbler setup in the lower portion of the memorial. BACKGROUND: Polymeric Sand Controlling weeds growing in the sand joints of the paver sections of Veterans Memorial Park is an ongoing maintenance concern that takes up staff time and can be costly if weed control spray is used. An alternative to sand joints is a product called polymeric sand. Polymeric sand sets up similar to concrete when it is placed, which limits weed and moss growth considerably. The one drawback to placing polymeric sand at Veterans Memorial Park is the difficulty in removing it when replacing pavers. In the formative years of the park there were quite a few paver purchases and staff was replacing a handful of pavers each year. Sales have slowed dramatically (there have been no sales in 2020) so the prospect of adding polymeric and is much more viable. Replacing a paver here and there will be manageable. Quotes were obtained from two companies for the work. Peterson Companies quoted $6,100 to do the work and Southview Design quoted $5,931.91. Southview also offered to repair a section of pavers that has fallen out of place for an additional $764.06. Bubblers The original bubbler system included five self-contained, independent systems to operate each bubbler. The pumps were cheap and needed to be replaced every year, the five independent electrical outlets were problematic, and water would often overtop the basins for each bubbler and flood out of the limestone wall. Staff has been researching ways to install a more robust system that only requires one pump and one electrical outlet. There is a pump that costs $250 and has the necessary power to serve all five bubblers. A special manifold for less than $100 will be used that has five individual valves to control each bubbler so that similar bubbling water heights can be maintained. The main cost will be in forming one continuous basin to serve all of the bubblers. Concrete is a possible solution but will also be more expensive. Staff is still researching other possibilities such as a resin trough or a simple pond liner. A grate will also be needed along with decorative rock and a faux rock to hide an access hatch. The total project cost should be in the neighborhood of $5,000 depending on the type of basin selected.
