Inadequacies in portions of the City's stormwater conveyance system cause some street flooding for brief periods after heavy rainfall. The City has identified problem locations and has underway an ongoing program of improvements. In planning to alleviate flooding, the City is addressing the dual considerations of stormwater removal and improvement of estuarine water quality by retrofitting existing systems and implementing best management practices in cooperation with the St. Johns River Water Management District. Estuarine Pollution The principal source of estuarine pollution originating within the City is "first-flush" of organic and metallic materials from streets and parking areas and nutrients and pesticides from residential landscapes entering the City's stormwater drainage system. These then discharge into finger canals, which flow into the Grand Canal. Improvement of estuarine pollution resulting from stormwater outfalls is a concern of the City and the St. Johns River Water Management District. The City has adopted on-site stormwater regulations for private development activities. In addition, siltation is an important source of pollution. This information is elaborated on in the Infrastructure Element of the Plan. Regulations currently in place and limited opportunities for future land development within the City (primarily residential uses) will eliminate any significant potential for increases in estuarine pollution. Well-water Discharge Well-water discharge contributes to the City's drainage. Well water empties into finger canals from a few remaining antiquated water-to-air air conditioner units. State law requires that water withdrawn from the Floridan Aquifer for heat exchange purposes be injected back into the Aquifer through a separate well, and City ordinances prohibit direct discharge of well water into the City's stormwater drainage system. To the degree that these laws and ordinances are enforced, well water discharge will occur only as sheet flow across lawns from shallow wells. As best as is known, the City has no problem with well water discharges into the City's stormwater system. In addition to flow from wells serving water-to-air air conditioners, well water used to irrigate lawns that does not evaporate or is not transpired by plants into the atmosphere enters the surficial aquifer at the water table. Water from free-flowing wells tapping the artesian Upper Floridan Aquifer that have failed below the surface of the ground (normally due to the iron well casing corroding through due to sulfuric acid in the well water (from dissolved sulfur dioxide)) also enters the surficial aquifer. This water then flows down-gradient until it encounters the bank of an open water body. With the network of drainage canals in the City draining into the Grand Canal in the western portion of the City, the groundwater almost inevitably seeps into the canals. This below-grade flow may be substantially more than the sheet flow and point discharges from pipes. Statistical analysis of ionic ratios in water samples collected at stormwater outfalls in the City in 1999 suggests that about 40% of the water in those samples had originated in the Upper Floridan Aquifer. Statistical analysis of the discharge from the DeSoto drainage basin versus rainfall for 2½ months in late 2001 suggests about one third of the water leaving that drainage basin at that time did not come from rain. Since the amount of potable Melbourne water discharged outside homes is negligible, this leaves water from wells as the likely source of this extra flow. These analyses are preliminary and do not constitute Coastal Management/Conservation Element Data and Analysis 5-8
conclusive evidence of large amounts of artesian water in the City’s stormwater system. However, they point in that direction and, if considered important, suggest further, more precise, analyses are necessary. Groundwater Resources The top of the Floridan aquifer, the deep water artesian aquifer underlying Satellite Beach, locally occurs at 200 to 250 feet below mean sea level (MSL). Over pumping of the aquifer has resulted in local seawater intrusion. Otherwise, the aquifer provides water with a salinity of about 5,000 parts per million in Satellite Beach - useable for irrigation, but exceeding Federal standards of no more than 250 parts per million salinity for potable water. Confined under the impervious Hawthorn Formation, the water in the Floridan Aquifer is artesian; it will rise above the surface of the ground in a tightly cased well. As such, there is no recharge of the Floridan Aquifer in the City; that occurs in western Orange and Lake Counties where the rock formations containing it lie near the surface without overlying impervious formations. The surficial aquifer is a non-artesian source of groundwater, recharged directly by infiltration of water from the ground surface. The quality of water drawn from the shallow aquifer depends on the source of recharge water and minerals in the soil. Water from the surficial aquifer underlying Satellite Beach often contains iron and sulfur. Due to this fact, the surficial aquifer is used only for shallow well irrigation systems. Natural Environment Satellite Beach is part of an intricate and delicate system--the coastal barrier island. This area naturally serves as the mainland's first line of defense against storms. Barrier islands are naturallyformed dynamic features which act as a buffer system between the ocean and the mainland. They absorb the impacts of storms, which reshape their geography and topography in response to natural conditions. Therefore, they are particularly vulnerable to strong winds, flooding, and erosion. Furthermore, the barrier island has unique environmental features. Due to the moderating influence of surrounding water bodies, the climate on the barrier island supports tropical species of plants normally found far to the south. Brevard County's barrier island to, approximately, Cape Canaveral, constitutes the northernmost limit of the range of many of these plant species. At the same time, the infrequency and mildness of freezes in the Central Florida region serves to define the southern limit of many plants found in temperate zones. Thus, the barrier island in the vicinity of Satellite Beach represents a unique climatological region which sustains unique habitats characterized by mixed tropical and temperate plant species, in addition to a significant number of endemic species only found in the local region. In order to protect coastal resources and critical habitat within the City, it is necessary to encourage the preservation and restoration of native vegetation, and to discourage the placement or maintenance of noxious plant species. The City has no programs which directly involve residents in preserving or restoring native habitats on their property. However, the City is involved with several projects Coastal Management/Conservation Element Data and Analysis 5-9
