ALL STlmy REACHES

Major Drainageway Planning
for
Tucker Gulch and Kenneys Run

I. Where land is subject to development or redp.velopment, the development

should follow master plan recommendations and be in accordance with

SELECTED PHASE B PLAN
(April 1983)

floodplain regulations.

GENERAL

2. Show the improvements recommended in the Phase A report dated January,
1983 and all the necessary plan, profile and detail information needed to
insure the recommended improvements will function hydraulically and
hydrologicly as intended.

The Phase B report and preliminary design shall be based on the selected
plan that includes the following:
1. Recommendation in the plan to enforce the 100-year floodplain regulation.
2. A discussion that clearly points out the need for regulating a residual
IOO-year floodplain that may remain after the plan is implemented. Also
point out that the existing 100-year floodplain has to be regulated until
it is modified by physical changes to the existing drainageway facilities.

Appendix A prepared by Ben Urbonas, UDFCD, and received by Muller Engineering
Company.

Planning for, or anticipating such changes does not justify regulating

anything other than the floodplain defined using existing channel

conditions.

3. Encouragement to purchase flood insurance.
4. A provision for an adequate maintenance access to all drainageway reaches.
Any separate maintenance trail should have a minimum flat surface width of

10 feet.

5. A provision for adequate erosion control for all channel improvements and

structures.

6. Recommend that new development in the watershed provide on-site erosion
control during construction to limit the amount of silt and earth washed
into the drainageway during frequently occurring runoff events.

7. Caution that improvements be generally prioritized to complete the

downstream facilities first and then proceed upstream to each successive
reach with the exception of upstream detention facilities. These, if
deemed appropriate, may be prioritized for early implementation.
