Memo Providing Cost Estimate for the Temporary Re-Establishment of Three Outdoor Natural Ice Rinks at Burns Park, Allmendinger Park, and Northside Park
Memorandum
Resolution R-15-081, passed on 3/16/2015 requested that the City prepare a cost estimate for outdoor ice rinks at Burns, Allmendinger, and Northside Parks.
The last two winters have had prolonged stretches of cold weather that could support outdoor natural ice rinks. In general the following weather conditions are desirable to establish and sustain a natural ice rink: an initial spell of cold weather that establishes a layer of frost in the ground, followed by weather where daytime high temperatures do not exceed 32 degrees Fahrenheit.
The following assumptions form the basis of the cost estimate:
* Rink size of 12,800 square feet (64' x 200)
* 4" ice depth established (less of a base puts the rink at greater risk of being totally lost during a warm stretch - Buhr, which has a cooled sub-floor establishes a 2" ice depth)
* 10 - 14 days to establish the rink (The process for establishing a rink is time consuming and is best done at night when the sun is down. This is the process followed at Buhr. Thin layers of water need to be applied over time or significant cracking will occur. The colder the night the quicker the process can go as the ice will set more rapidly)
* Daily maintenance once the rinks are established, including brooming/snow removal/adding water/repairing ice damage when possible, and cleaning/open/closing shelters
* Rinks maintained for 45 days after their establishment
* Warming shelters open at Burns and Allmendinger from midday to early evening (Northside shelter presently used by Community Action Network for social services)
* Utility costs for water to establish and maintain rinks and increased gas and electric at shelters factored in
* Two cost estimates are provided. One assumes the rink perimeter is made of snow, and the other assumes a...
