| | #1 NO EXISTING OR PROPOSED DRAINAGE IS SHOWN: |
| | TYPICAL SURFACE WATER CRITERIA: SFWMD, APPLICANTS TREAT |
| | FIRST INCH OF RUNOFF OR 2 1/2 TIMES THE IMPERVIOUS |
| | AREA, WHICH EVER IS GREATER. |
| | |
| | #2 PROVIDE PROPOSED PERVIOUS AND IMPERVIOUS |
| | CALCULATIONS. THESE FIGURES WILL BE USED TO UPDATE |
| | STORM WATER ACCOUNT. |
| | |
| | NOTE: 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; HOWEVER WE RECOGNIZE THAT THE FIRST FLUSH |
| | FROM THE IMPERVIOUS 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 YOUR CONSTRUCTION. |
| | ANY MODIFICATION SHALL INCORPORATE STORMWATER BMP?S |
| | SUFFICIENT TO DETAIN THE FIRST FLUSH FROM THE |
| | REFERENCED IMPERVIOUS 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. |
