The ponding probably does not pose any problem, because the water
does dry out after a few days, making the lawn area usable, but several
solutions are available to correct the periodic ponding. Installation of a
catch basin, as shown in Figure 14.17-B, is one solution, probably a costly
one. Bringing in topsoil to raise the area so that water can flow to a more
desirable location is another possibility. Most likely, nothing will be done
because of the costs involved in correcting a situation that is a tempo-
rary nuisance, one that students and the university groundskeepers can
live with, at least for the time being.
In many cases it is not possible to
manipulate the topography to sheet-
drain water to another location. In those
instances, installation of one or more catch
basins would ensure that storm water is
dispersed to another location to reduce
flooding or unwanted detention of surface
water around the building. Figure 14.18
