AN OPERATION AND MAINTENANCE MANUAL FOR ALL POST-CONSTRUCTION STORMWATER QUALITY MEASURES: a. THE PROJECT INCLUDES THE CONSTRUCTION OF AN ADDITION TO AN EXISTING SINGLE-STORY COMMERCIAL/RETIAL BUILDING AS WELL AS ASSOCIATED PARKING AND UTILITY SERVICE INFRASTRUCTURE. STORMWATER RUNOFF FROM THE DEVELOPED SITE WILL FOLLOW EXISTING DRAINAGE PATTERNS TO THE GREATEST EXTENT POSSIBLE AND IN ACCORDANCE WITH THE MASTERPLAN PARAMETERS AS PREVIOUSLY APPROVED BY THE CITY OF CARMEL. ALL PROPOSED ONSITE IMPERVIOUS SURFACES WILL DIRECT RUNOFF TO A DOWNSTREAM STORMWATER PIPE NETWORK AND ULTIMATELY THE EXISTING STORMWATER DETENTION POND TO THE EAST. THE PROPOSED DEVELOPMENT WILL LIMIT THE DISCHARGE TO THE EXISTING DOWNSTREAM PIPE NETWORK IN ACCORDANCE WITH THE APPROVED MASTER PLAN FOR THE SITE. AS REQUIRED BY SECTION 302.06(7) OF THE MANUAL, A SUMMARY OF PROPOSED RUNOFF/DISCHARGE IS PROVIDED HEREIN. b. OWNER OF BMP: N/A 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. PLEASE SEE THE O&M MANUAL FOR SPECIFICATIONS , DETAILS, AND INSPECTION REPORT REQUIREMENTS RELATED TO THIS PROJECT.
