DC has invested tens of millions of dollars building new - and renovating old - outdoor aquatic facilities. For hundreds of thousands full-time working parents, students and all others who want to visit a pool to cool down during hot summer weekends, the noon start time makes it difficult, if not impossible, for many to enjoy the facilities. Shade is limited at most all pools and opening just as the sun is at its peak makes it dangerous for the elderly, toddlers and anyone trying to avoid intense sun. By 1pm, the facilities become over-crowded, even dangerous, for younger kids.
Opening the facilities at 10am allows time to enjoy the pool before the noontime sun, it gives older citizens, younger children, parents and other early risers to use facilities before the crowds arrive. Finally, and maybe most importantly, it is a good way to spend a small portion of the budget surplus, giving taxpayers of DC the opportunity to use facilities built with tax revenue.
