RE: Interlocal Agreement for FEMA Funded Stormwater Drainage Projects between the City of
Miami and Miami -Dade County (MDC).
Dear Mr. Espinosa:
Recently, your department completed the dredging of the Comfort Canal from a FEMA funded
stormwater drainage project. The estimated cost is $3,754,280 which required a 12.5% local matching
fund or $469,285.
Your department estimated. the City's. Cost Share. at 92% of the local matching fund or $431,742 in a
letter dated February 22, 2006. While we completely support this project and see the benefits in flood
protection, we do not agree upon the percentage of 92% that is shown on attachment "A" of your
package. We have consulted our drainage atlas and discovered that the basin boundary drawn in your
package does not match the existing site condition. Furthermore, other entities should have been included
in this table. The missing entities are MDX, FDOT-6, and Miami Dade County.
Our drainage approach within the City has been to maximize underground infiltration of our street runoff.
Direct discharge to canal or other body of water is kept to a minimum and avoided by approved alternate
drainage system. This Public Works policy effectively eliminated hundreds of acres from discharging
directly into the Comfort Canal. As a result, our estimate of the City's cost share is much less. We have
prepared a basin boundary map and a table reflecting the percentage by area of the major contributor to
the Comfort Canal. In this map you will notice all the major outfall areas to this Canal are owned either
by FDOT-6, MDX or Miami -Dade County. Our contribution to the tributary areas of the Comfort Canal
is estimated at 76%.
Please revisit the.estimate and forward any revisions at your earliest convenience.
