| 2013-12-13 11:28:08 | ABSENCE OF STORM WATER |
| | IN MANY PARTS OF THE CITY THE ABSENCE OF ANY STORMWATER |
| | BMP (STORMWATER BEST MANAGEMENT PRACTICES) IN SITES |
| | ALLOWS THE BOTH THE WATER VOLUME AND |
| | CONTAMINANT/POLLUTANT LOAD TO ENTER OUR SYSTEM |
| | UNTREATED. WHILE WE BELIEVE OUR EXISTING SYSTEM IS |
| | SUFFICIENT TO SERVICE THE STORMWATER VOLUME FOR YOUR |
| | PROPOSED USE, WE RECOGNIZE THAT THE FIRST FLUSH FROM |
| | THE PARKING AREA CONTAINS 90% OF THE |
| | CONTAMINANT/POLLUTANT LOAD FROM RAIN EVENTS AND THIS |
| | LOADING IS TRANSFERRED TO THE CITY?S STORMWATER SYSTEM. |
| | |
| | ACCORDINGLY, THE CITY HAS THE AUTHORITY TO IMPOSE |
| | STORMWATER BMP?S ON THE ENTIRE SITE WITH OR WITHOUT THE |
| | PROGRESSION OF THE PROPOSED WORK. HOWEVER, IN |
| | CONSIDERATION OF THE SCOPE OF THE PROPOSED |
| | IMPROVEMENTS, THE CITY HAS THE AUTHORITY TO THROTTLE |
| | IMPLEMENTATION OF BMP?S. IN THIS CASE, OUR |
| | RECOMMENDATION IS THAT YOU AS THE PROPERTY OWNER SHALL |
| | DESIGN AND MODIFY THE EXISTING STORMWATER |
| | INFRASTRUCTURE SERVING THE EXISTING PAVED AREA THAT HAS |
| | BEEN IDENTIFIED BY THE PLANNING AND ZONING DEPARTMENT |
| | AS REQUIRED SUPPORTING THE PARKING USE. |
| | |
| | ANY MODIFICATION SHALL INCORPORATE STORMWATER BMP?S |
| | SUFFICIENT TO DETAIN THE FIRST FLUSH FROM THE |
| | REFERENCED PAVED AREA. OWNER MAY PROPOSE AN ISOLATED |
| | SYSTEM THAT DETAINS AND PERCOLATES. PLEASE REFER TO THE |
| | SOUTH FLORIDA WATER MANAGEMENT DISTRICT MANUAL, IT?S A |
| | GOOD GUIDE TO SEE THE OPTIONS THAT MAY WORK WITH YOUR |
| | SITE. PLEASE LOOK AT THE OPTIONS FOR NONSTRUCTURAL |
| | BMP'S AND STRUCTURAL BMP'S. WE BELIEVE ANY OF THESE |
| | MODIFICATIONS REFLECT REASONABLE IMPROVEMENTS TO THE |
| | EXISTING CONDITIONS AND ARE CONSISTENT WITH PRACTICES |
| | OF BOTH THE CITY AND SOUTH FLORIDAWATER MANAGEMENT |
| | DISTRICT. |

| | |
| | OTHER OPTIONS TO MAINTAIN THE INTEGRITY OF THE PAVED |
| | AREA WOULD BE TO SEALCOAT AND RESTRIPE; HOWEVER YOU |
| | MUST CONVERSE WITH PLANNING AND ZONING DEPARTMENT AS TO |
| | THE USE OF SUCH SITE. |
| | |
| | THE CITY'S NPDES MS4 PERMIT AUTHORIZES THE CITY TO |
| | DISCHARGE STORMWATERS TO WATERS OF THE STATE IN |
| | ACCORDANCE WITH THE STORMWATER MANAGEMENT PROGRAMS |
| | (SWMP). THE SWMP INCLUDES POLLUTION PREVENTION |
| | MEASURES, TREATMENT OR REMOVAL TECHNIQUES AND OTHER |
| | APPROPRIATE MEANS TO CONTROL THE QUALITY OF STORMWATER |
| | DISCHARGED FROM THE MS4. ONE COMPONENT OF THE SWMP IS |
| | TO REDUCE THE DISCHARGE OF POLLUTANTS IN STORMWATER |
| | FROM REDEVELOPED AREAS CONSISTENT WITH THE SFWMD ERP |
| | REQUIREMENTS. |
| | |
| | RE-DEVELOPMENT PROJECTS ARE TO PROVIDE THE MINIMUM |
| | WATER QUALITY TREATMENT FOR THE GREATER OF 1" OF RUNOFF |
| | OR 2.5" TIMES PERCENT OF IMPERVIOUSNESS. THESE |
| | CALCULATIONS WILL BE REQUIRED WITH YOUR PLAN |
| | SUBMITTALS. |
| | |
| | THANK YOU FOR YOUR ATTENTION! |
