Answer:
There have been several ideas and suggestions about how we should deal with the detention basin. It is our main expense. It is not a small piece of property, and it does take some effort to maintain. We have been researching these suggestions to see if there are any changes that would make sense for our situation. Here is what we have learned.
The current landscape of the detention basin was approved by Provo City when the neighborhood was being developed. Any changes to the landscape of the detention basin need to be approved by the city. Provo City has very specific requirements for what needs to be included in the landscape design of a detention basin. This includes grass, trees and shrubs (see below). Grass is the main element that allows the detention basin to function, because grass is vegetation that anchors down the soil while allowing water to flow into the ground and the drains.
One idea has been to convert the land into a community garden. We have discussed this option with Thomas McKenna who oversees Provo City parks and open space areas. He explained that community gardens are not on the approved list of landscape designs for detention basins and a garden would not be approved because it would not allow the storm water drains to work properly. The debris that would run off from rainfall in a garden would be problematic and counterproductive.
Another suggestion has been to xeriscape the land. Xeriscaping is a landscape style which aims to minimize water usage by covering the ground with native and drought tolerant plants. It is doubtful that such a landscape would be approved by the city, as it is not listed in their requirements for detention basins in the city code. If we were somehow able to obtain approval for a xeriscape design for the detention basin from the city, it would mean a substantial cost to completely re-work the land in that manner.
Some have asked why we need to keep watering and mowing the grass in the detention basin; perhaps we should just let it die out. The board has spoken with three city planners who all stated that if we were to stop maintaining the detention basin, we would all face penalties, both as a group and as individual lot owners. Those penalties would include fines and liens on each lot in the neighborhood.
This is what the city code specifies for detention basins:
City Code 15.20
(d) Detention/retention basins and ponds shall be landscaped where possible. Such landscaping may include shade and ornamental trees, evergreens, shrubbery, hedges, turf and ground cover.
14.49C.140. Detention Basin - Wetlands Mitigation.

Approval from the City shall be required prior to the change of use or modification of such common areas. A detention basin/wetlands mitigation area related hydraulic features shall be the responsibility of the City. (Enacted 2007-26)
15.20.150. Enforcement.
