into a concrete lined ditch leading directly to the overflow gully

near the Air Force Academy boundary, From here, the flow follows

this overflow gully to Monument Creek. For reasons to be dis-

cussed under the section on special problems, this box structure

is too small to carry the lOO-year flow,

Numerous smaller sewer systems and

culverts exist in tpe western portion of the basin, The storm

sewer systems are listed in the Appendices E & F and will not be

described in detail here. In general, the sytems constructed in

the recent subdivisions (mostly within the City Limits at this time)

are adequate in size and drain their areas reasonably well. A few

additions and changes are proposed herein, but in general, the newer

areas appear to be properly drained according to the City criteria

for drainage,

Drainage in the older subdivisions

is somewhat erratic, These subdivisions were designed with road-

side ditches, for the most part, with culverts placed at road inter-

sections and numerous low, swampy areas used for flood storage.

This system tends to channel flow into the low areas and has been

almost completely inadequate.

Some more extensive drainage systems

exist, primarily in the Brookwood area. We could not determine

when these were placed, The distribution of these systems would

indicate that they were constructed in response to drainage problems

in the past. These systems appear to fit the City drainage criteria

insofar as pipe size is concerned, Inlet capacity is inadequate,

however.
