INSPECTION AND MAINTENANCE OF ALL AREAS IS THE RESPONSIBILITY OF THE CONTRACTOR UNTIL ACCEPTED BY THE GOVERNING MS4 OFFICE. INSPECTION AND MAINTENANCE OF BMP'S SHALL FOLLOW TIME TABLES SET FORTH IN THE MAINTENANCE AND OPERATIONS MANUAL. 4. STORMWATER QUALITY MEASURES TO BE IMPLEMENTED TO PREVENT OR MINIMIZE ADVERSE IMPACTS TO STREAM & RIPARIAN HABITATS. THE PROPOSED, TURF, AND LANDSCAPE PLANT MATERIAL WILL GENERATE VERY LITTLE IF ANY POLLUTANTS THAT COULD CAUSE HARM TO STREAM OR RIPARIAN. THE PROPOSED AQUASWIRL WILL CAPTURE FLOTABLE DEBRIS AS WELL AS SEDIMENT PROVIDING MORE THAN 80% TOTAL SUSPENDED SOLIDS REMOVAL. 5. AN OPERATION AND MAINTENANCE MANUAL FOR ALL POST-CONSTRUCTION STORMWATER QUALITY MEASURES: a. THE PROJECT INCLUDES THE CONSTRUCTION OF A NEW THREE-STORY BANK AND MULTI-TENANT COMMERCIAL BUILDING AS WELL AS ASSOCIATED PARKING, DRIVE AISLES, LOADING AREAS AND UTILITY SERVICE INFRASTRUCTURE. STORMWATER RUNOFF FROM THE DEVELOPED SITE WILL FOLLOW EXISTING DRAINAGE PATTERNS TO THE GREATEST EXTENT POSSIBLE. ALL PROPOSED ONSITE IMPERVIOUS SURFACES WILL DIRECT RUNOFF TO A DOWNSTREAM STORMWATER PIPE NETWORK, STORMWATER QUALITY MEASURES AND ULTIMATELY THE EXISTING STOMRWATER DETENTION POND TO THE WEST. THE PROPOSED DEVELOPMENT WILL LIMIT THE DISCHARGE TO THE EXISTING DOWNSTREAM PIPE NETWORK IN ACCORDANCE WITH THE APPROVED MASTER PLAN FOR THE SITE. SOME AREAS WILL BE SUBJECT TO DIRECT SHEET DRAIN RUNOFF BUT THOSE WILL BE LIMITED TO AREAS LESS THAN OR EQUAL TO THOSE CONTRIBUTING UNDER EXISTING CONDITIONS AND AREAS OF PERVIOUS SURFACE COVERAGE. AS REQUIRED BY SECTION 302.06(7) OF THE MANUAL, A SUMMARY OF PROPOSED RUNOFF/DISCHARGE IS PROVIDED HEREIN. b. OWNER OF BMP: TBD C/O TBD ADDRESS CITY, STATE ZIP CODE c. BMP OWNER ASSUMES ALL OPERATIONAL AND MAINTENANCE COSTS FOR BMP. d. BMP OWNER SHALL GRANT ACCESS TO THE CITY OF CARMEL TO MAINTAIN THE BMP AS NEEDED. 6.
