III. KINGGULCH

1. From 15th Street Upstream

a. Minimal Channel Work. Some erosion protective works would
be constructed to protect homes and minimize debris trans-
port downstream.

b. Channel Rectification. Proper channel cross section would
be established which would include disruption of certain
home arrangements.

2. 15th to 17th Streets

An open channel would be established with wide top width and a
small sediment trap.

3. 17th to Outfall Poi nt

a. Construct underground conduit to Skunk Creek down King
Street.

b. Construct underground conduit east on King Street to 18th
Street and then to Bluebell Canyon Creek to the north.

IV. SKUNK CREEK

1. E.S.S.A. Land and Cemetery

A series of sediment detention ground level ponds with flood hydro-
graph detention capability would be constructed downstream from
Kohler Reservoir. The ponds would be landscaped to provide a park-
like appearance. Opportunity exists here for gravel sales and the
"synergistic" approach to solid waste disposal in the event that
the Federal government was willing to cooperate.

A channel would be excavated to carry the 100 year flow down to
the cemetery land In a slow manner. Bermlng would be used as needed
to provide additional protection to the E.S.S.A. labs, such pro-
tection approaching that for the maximum probable flood occurrence,
if found to be reasonable.

Crossing of the cemetery is fraught with land problems, and because
of that, a containment approach would be utilized whereby berms
would be built at the perimeter where needed to guide the water to
the proper downstream outlet at 22nd and King Avenue. Within the
cemetery, water would be allowed to spread freely.
