In addition, the surface of any ~""" dock, sundeck, or floor of any boathouse, gazebo, etc. shall not be more than two (2) feet above the elevations specified in Section (4)(e). (6) In order that all docks or boathouses be utilized only for boating or other "" recreational activities and not as living space, there shall be no bathrooms or cooking facilities permitted in them, nor as an improvement to the existing boathouse.

The following standards shall apply to all construction on lake front, marsh front, canal front or stream front lots: (1) Intracoastal, lake front, marsh front, canal front and stream front lots shall be developed to maximize the amount of natural rainfall which is percolated into the soil and to minimize direct overland runoff into the water. With the exception of boathouses, docks or other over-water construction, stormwater runoff from structures and other impervious surfaces shall be directed into on-site retention swales and percolation of the first one inch of runoff. Properties being developed or redeveloped shall eliminate any direct piped discharges of stormwater into the water, so that this runoff is directed to the on-site retention and percolation areas. The city staff may require, as conditions necessitate, the submission of soil and water table information, topographic detail, drainage calculations and professionally designed plans so as to insure these requirements are met. All stormwater retention compliance shall prioritize the preservation of existing trees and the impacts of fill or excavation on tree root systems shall be minimized. (2) No intracoastal, lake front, marsh front, canal front or stream front lot owner shall grade the lot in such a way as to interfere with the natural drainage of adjoining lots or in a way that diverts drainage from their lot onto adjoining lots. The city staff may require, as conditions necessitate, the construction of physical features, grading, swaling and piping of roof gutters so as to insure that runoff on a lot does not negatively impact adjoining lots.
