Subterranean basements and parking structures have been constructed in South Florida for decades, with some dating back to the 1960s. Geotechnical studies have shown that subterranean conditions are suitable for underground construction and proposed development at the site. Environmental impacts would be similar for the project with or without a subterranean component as both types of construction involve the same type of construction activities (i.e. deep foundation installation, dewatering, and excavations). The WMODA Team has taken great concern and expense to build the garage in this configuration. It is largely due to the concerns of the public to not have an unsightly parking structure intertwined with the residential building that this was undertaken.
Measures to Comply with Environmental Regulations: Below is a list of specific measures that will be taken to comply with applicable environmental requirements for subterranean parking work:
Erosion & Sediment Controls: Erosion and sediment controls will be installed around the site in accordance with the requirements of the Florida Department of Transportation (FDOT) and the Florida Department of Environmental Protection (FDEP), as designed by the licensed Civil Engineer of Record. These measures will be implemented prior to site disturbance and throughout excavation.
Dewatering Operations:
· All necessary permits will be obtained from relevant state and local authorities.
· Compliance will be maintained with rules and regulations enforced by the FDEP.
· The project will also comply with regulations set forth by the Southeast Florida Water Management District.
· Dewatering systems, including wellpoints, will filter discharge and sediment, and an additional filtration tank will provide secondary filtration before discharge.
· If necessary, groundwater monitoring systems and groundwater recharge systems may be employed, although this has not been recommended by subcontractors consulted for this project.
Additionally the following are a list of benefits from the proposed subterranean garage:
· Less stormwater runoff
· Control of liquid Pollution
· Control of solid waste
· More greenspace
· No obstruction of views
· No obstruction of sunlight
· Car noise abatement
· No contribution to heat islanding.
