"~ SUBJECT: Follow-up eport
Ocean Outfall Lines at 7th and 10th Streets; A question was raised at the last commission
meeting about what the City intended to do with the remaining storm water outfall structures on
the beach at the 10th and 7th Street access points. These were originally designed to carry storm
water out of Atlantic Beach to the ocean. The drainage that fed into these outfall lines was
redirected as part of the recently completed Core City Project so that these areas would now
drain to the Selva Lagoon system and ultimately out to the intercoastal waterway. The
redirection of drainage waters away from the beach areas has been encouraged by the state for
several years. However, the outfall structures on the beach still remain. The designer of the
project, Neil Aikenhead, specifically left these structures in place with the idea that they would
be available for use incase of catastrophic rain events in the future. If such a rain event were to
occur, and the Selva Lagoon system could not handle the storm water, it would be possible to
temporarily unplug the old lines leading to the beach to help relieve those flooding conditions.
Staff s recommendation is to leave these structures in place, although steps can be taken to make
them less objectionable. The sand around these structures has eroded in the past because of the
flow out of the structures to the beach. Since these lines were rerouted, much of the sand that
was eroded has migrated back and the structures do not stick out as far as they did. If the sand is
not completely returned to its normal level by the time of the expected 2005 Renourishment
Project, then it can be filled in at that time. In the meantime, city staff will paint over the graffiti
that was recently painted on some of the structures.
State Law on Sneed Bumps; One question raised during a recent discussion about possible
installation of speed bumpslhumps along Plaza Drive was whether or not any state law exists that
would limit the city's authority to install speed bumps/humps along that street. This question has
been researched by the Police Department which was unable to find any state laws that restrict
the use of speed bumps/humps on city streets. There are numerous jurisdictions that implement
traffic calming devices of various sorts, including speed bumps/humps.
