PRE-DEVELOPMENT SITE INFORMATION This 0.9 acre piece was previously developed and was occupied by one single family home as well as a triplex residential unit until 2016. The property drained to the public infrastructure along Ahern Street and East Coast Drive. Due to its proximity to the ocean, we have noted through site visits that the soil is very sandy with a low groundwater table. POST-DEVELOPMENT SITE INFORMATION This project will bring 4 townhome buildings with pervious parking and paver courtyards. All stormwater runoff will be collected and taken to two dry swales along the northside of the project. The ponds have been sized to provide treatment to dry retention standards of the F.A.C. and attenuate the 25 year 24 hour and mean annual storm events. Due to the total size of the project (0.90 acres) and with an impervious area less than 2 acres, this permit is being processes as a 10/2 Self Certification through the FDEP webs ite. Maintenance The applicant will be responsible for all maintenance.
