No existing public storm system is located on site or adjacent to the site. Site is graded to provide positive drainage away from the building with the roof drains connected to the underground storm system. A series of curb inlets and catch basins collect the runoff from the site and discharge into the detention pond located on the West side of the property. The outfall of the pond is controlled by a weir structure. This structure has been designed to release the runoff for the 1yr, Syr, and 100yr storms at the pre -development allowable rates. The outfall discharges at the southwest corner of the property maintaining the pre -development drainage pattern. The drainage system consists of reinforced concrete pipes (RCP) inlets and manholes. PRE -DEVELOPMENT CONDITIONS The 6.42 Ac site drains towards the southwest corner of the property and consists of one drainage basin (A-1). An offsite area of approximately 2.24 Ac (OS-1, OS-2, OS-3) discharges onto this property thru a series of three (3) curb openings. The runoff from this area will be diverted to bypass the detention pond. Refer to C8.00 for details. POST -DEVELOPMENT CONDITIONS The post development conditions will mimic the pre -development conditions. The offsite area will remain mainly unchanged, and the runoff diverted through an earth swale and culvert around the pond. The main drainage basin (P-1) is diverted into the proposed storm water detention pond via storm system. A weir structures controls the release to maintain the pre -development rates. Refer to C9.00 for details. HYDROLOGIC DESIGN ANALYSIS The storm water analysis was performed in accordance with the City of Fort Worth iSWM Criterial Manual. The pond sizing calculations were developed using the modified rational method and the spreadsheet tool provided by the city. The rainfall intensities are based on iSWM Technical Manual for Tarrant County. The maximum allowable discharge rates for this property are as follows: Ql = 6.42 cfs; Q5 = 9.25 cfs; Qioo = 15.03 cfs Post -development and detention pond discharge rates: Ql = 6.42 cfs = 6.42 cfs (pre-dev) WSE, = 793.38' Q5 = 9.25 cfs = 9.25 cfs (pre-dev) WSE5 = 794.32' Qioo= 15.03 cfs = 15.03 cfs (pre-dev) WSEloo= 796.00' EL - 7!1 I \ \ !'CtlICIiR AIYoEIF IF �� 4RPO ED CAMEo0 IG; O o I., i oEL e79LT� SIDE YAMFNNRE C ACCESS RAMP IS MAI E / NEW YULT SLOE \ WIFALL SiRUCI1IRE.

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.
