DETENTION SUMMARY POND OD-20
A DETENTION FACILITY HAS BEEN DESIGNED TO SERVE THE PROPOSED
SPEEDWAY I INDUSTRIAL PARK — BUILDINGS 2 8 3 DEVELOPMENT IN ORDER TO
CAPTURE THE STORMWA TER RUNOFF FROM DRAINAGE AREAS 'D—l', 'D-2c',
'D-2b' , 'D-3c' , 'D-3b' , 'D-3c' 8 'D-4 ' . AREAS 'D—l' , 'D-2c'
AND 'D-2b' ARE ROUTED THROUGH DETENTION POND 'D-2A ' AND DISCHARGE
TO POND 'D-2' THROUGH A 33' R.C.P. PIPE. AREAS 'D-3c' , 'D-3b' ,
'D-3c' 8 'D-4' WILL DRAIN DIRECTLY INTO DETENTION POND 'D-2' .
DETENTION POND 'D-2' WILL THEN OUTFALL ABOVE WSEL = 675.50 VIA
THREE (3) 24' R.C.P. PIPES.
THE DETENTION ANALYSIS WAS PERFORMED UTILIZING THE U.S. ARMY CORPS
OF ENGINEERS HEC—HMS v4.3 UNIT HYDROGRAPH COMPUTATION PROGRAM
USING SCS METHODOLOGY. A HYDROGRAPH WAS GENERATED FOR THE DRAINAGE
AREA BEING DETAINED AND THEN ROUTED THROUGH DETENTION POND 'D-2' .
THE /00—YEAR DISCHARGE FROM THE PROPOSED POND HAS BEEN CAL CUL A TED
TO BE 43.8 CFS. REFER TO THE FINAL ISWM FOR DETAILED CALCULATIONS AND
ANAL PSIS OF THE DOWNSTREAM SYSTEM CAPACITY.

DOEMION SUMMARY POND 'D-2A"
A DETENTION FACILITY HAS BEEN DESIGNED TO SERVE THE PROPOSED
SPEEDWAY l INDUSTRIAL PARK - BUILDINGS 2 8 3 DEVELOPMENT IN ORDER
TO CAPTURE THE STORMWATER RUNOFF FROM DRAINAGE AREAS 'D-l' ,
'D-2o' 8 'D-2b' . THESE AREAS WILL DRAIN TO DETENTION POND
'D-24 ' . DETENTION POND 'D-2A ' WILL THEN OUTFALL ABOVE
WSEL = 676.60 V14 ONE (l) 33' R.C.P. PIPE.
THE DETENTION ANAL YSIS WAS PERFORMED UTILIZING THE U.S. ARMY
CORPS OF ENGINEERS HEC-HMS v4.3 UNIT HYDROGRAPH COMPUTA TION
PROGRAM USING SCS METHODOLOGY. A HYDROGRAPH WAS GENERATED
FOR THE DRAINAGE AREA BEING DETAINED AND THEN ROUTED
THROUGH DETENTION POND 'D-2A ' .
THE IOO-YEAR DISCHARGE FROM THE PROPOSED POND HAS BEEN
CALCULATED TO BE 23.3 CFS. REFER TO THE FINAL ISWM FOR
DETAILED CALCULATIONS AND ANAL PSIS OF THE DOWNSTREAM
SYSTEM CAPACITY.

EXHIBIT B
Exhibit "C"
CITY OF FORT WORTH STORMWATER FACILITY
OPERATION AND MAINTENANCE PLAN
The only responsibility the City of Fort Worth has in the operation and
maintenance of this Facility is inspection.
General Maintenance Procedures
The structural and functional integrity of the Facility shall be maintained at all
times by removing and preventing drainage interference, obstructions, blockages,
or other adverse effects into, through, or out of the system.
Periodic silt removal shall occur when standing water conditions occur or the
pond's storage volume is reduced by more than 10%. Silt shall be removed and
the pond/basin returned to original lines and grades shown on the approved
engineering plans. In addition, corrective measures are required any time a basin
does not drain completely within 72 hours of cessation of inflow. NO STANDING
WATER IS ALLOWED in basins designed for dry detention purposes.
Accumulated litter, sediment, and debris shall be removed every 6 months or as
necessary to maintain proper operation of the basin. Disposal shall be in
accordance with federal, state and local regulations.
Detention facilities shall be mowed monthly between the months of April and
October or anytime vegetation exceeds 12-inches in height.
To prevent debris from entering and clogging the downstream storm sewer
system a wire mesh screen or similar screening device shall be installed over the
outlet until final acceptance.
4. PREVENTIVE MAINTENANCE/INSPECTION
• Visual inspections of all components will be conducted every 6 months.
• A log shall be kept of maintenance actions, and inspections. The log
should document the condition of the detention system's primary
components, mowing, and silt, litter and debris removal dates. Document
aeration of the basin bottoms and replanting to prevent the sealing of the
basin bottom.
• Written maintenance and repair records shall be maintained by the
party or parties signing the attached Agreement and shall be provided
to the City upon request.
