Attention: Mr. Ralph White, Clerk
Gentlemen:
Cow Key Channel Bridge, D.O.T. No. 900075,
. Monroe County, D.E.R. No. 44-37-3681
A biological survey of the above referenced project has been
performed by our staff, and the following comments are provided:
The applicant proposes to replace an existing
deteriorated section of bridge with a concrete
structure supported on 40 vertical pilings. A
relatively small amount (approximately 120 cubic
yards) of fill material is to be placed below mean
high water for the bridge approaches. Approximately
110 cu. yds. of material are to be dredged in
setting the pilings.
The subject bridge spans Cow Key Channel and connects
Stock Island with Key West. The upland and slope substrate
consist primarily of coral rock fill. Submerged bottoms
consist of a deep layer of fine sand and silt over cap
rock. This is vegetated by filamentous green algae
and scattered turtle grass. Shoreline vegetation along
the southeast embankment includes red, white and black
mangroves, railroad vine, glasswort, and sea purslane.
The northwest embankment has been cleared. On the
southwest embankment shoreline vegetation is sparse,
while some turtle grass and filamentous green algae
are found below mean high water.

The proposed project should have minimal adverse
effects provided the following conditions are
incorporated:
1. Removal of the existing structure should
entail no filling or other disturbance of
adjacent vegetation.
2. Adequate turbidity controls should be utilized
during filling and drilling activities.
3. Fringe vegetation disrupted by project
construction should be replaced to stabilize
slope and provide shoreline buffer.
4. Surface runoff should be directed to the
upland to allow filtration by percolation.
