Stevenson Creek Presentation:
Mr. Hunsicker provided an overview of the Stevenson's Creek Project
to the committee to provide flood protection to residents in the
Stevenson Creek watershed. The city is required by federal
regulation to protect water quality. To accomplish the mission of
flood protection, the city has elected to increase the stormwater
capaci ty of Stevenson Creek, as a means of reducing property
flooding. Mr. Hunsicker stated that Phase I of Stevenson Creek
has been permitted by Environmental Regulatory Agencies, and
therefore, would also protect water quality. plans are now being
considered by local contractors.
Mr. Baker was then introduced and presented a chart of the entire
watershed of Stevenson Creek, including construction of Phases I
and II. He discussed the removal of sediment by means of a
sediment trap. Mr. Baker stated that it will ultimately be an
15"";'-.

environmental enhancement once the pro ject is completed. The
mitigation of disturbed wetlands was discussed due to the
construction of Phase I. The mitigation will be constructed in the
Clearwater Country Club golf course. Mr. Baker also explained that
re-channeling leads to greater storrnwa ter velocities. Higher
velocities cause serious erosion, therefore the need for additional
hardlining. Mr. Baker indicated that where hardlining is not
necessary, natural wide earthen sections would be used. Mr. Baker
discussed at length the location of the proposed channel and the
new drainage structure improvements.
Discussion ensued regarding Mr. Foley's Stevenson Creek "Natural
Plan" and the drainage cri teria used to model Stevenson Creek
hydrology.
Stevenson Creek Sub-Committee Report
Mr. Foley presented and discussed recommendations for City
Commission consideration in reference to Stevenson Creek
(Attachment A). These comments were recognized as Mr. Foley's
comnlents and were not necessarily the comment of the Subcommittee.
Mr. Mazur discussed and elaborated on the memorandum submitted to
the Committee members by the Stevenson Creek Subcommittee
(Attachment B), in which 5 recommendations were listed. These
recommendations included:
1. Verify that proposed engineering solution properly
accounted for blocked culverts (at Cleveland Street,
Pierce Street, Franklin Street, Court Street, Druid
Street and Jeffords Street) that, which from all
indication may have existed for the calibration event.
2. The "natural plans" (per Tom Reese letter of ,1991)
positive affect on existing flooding conditions has never
been determined since the intent of the "natural plan"
was to reduce structural solutions to the maximum extent
practicable in support of features to return and enhance
the natural functions of the creek.
3. Modify the current "City Plan" to utilize Glen Oaks to
the maximum extent possible for water quality, quantity
and environmental benefits.
4 . Determine whether the purchase of flood damaged homes
upstream of Belleview Boulevard is more economical than
the current "City Planll in that vicinity.
5. Stevenson Creek should receive the highest priority for
implementation of a comprehensive watershed plan in
accordance with NPDES guidelines and comprehensive Plan
Policies 16.2.8 and 17.1.5.

committee being left off - decided to defer it tl'1is meeting and approve these minutes r
B. no modifications
II A. 1. Distributed list of current stormwater retention ponds, both in working and non-
working order. Terry Finch addressed the committee and will look into getting us
better descriptions of the ponds.
2. Stormwater utility was adopted on Dec. 20
B. Legislative Watch List was passed out, and Mr. lVIiller discussed a few items.
Stormwater was also discussed. Mr Miller will pull together a description of what a
.. good stormwater system is (easily maintainable and what functions best); Terry
Finch has a good brochure being printed she can bring; well head protection a topic
to be discussedat a later meeting; Mr. Mazur Vlill bring someonein to talk about
pond design; Mr. Hunsicker informed us that every site plan that comes in for the
city has to have storlnwater facilities.

according to the 6 main programs listed above. A motion was made to accept this
list.
