RETAIN. www.Faschcomp(inV.com com May 20, 2024 Re: Wall Maintenance PWI - Fort Worth These walls are designed and constructed in accordance with the wall plans and specifications and will perform as long-term retaining wall structures. Please refer to the notes on the engineered drawing that state: "Structural design herein represents a finished structure. It will be the responsibility of Arco to protect the walls from damage by other construction activities and from inclement weather. Our experience is that there are several ways that retaining walls can be damaged during construction and after completion. We recommend you review the following potentially harmful situations with your onsite personnel to take necessary actions to prevent them from occurring. Arco should protect and maintain the retaining walls from damage during the remainder of construction of the project. The following are potential issues that can occur if proper steps are not taken to protect the walls. • Heavy equipment shall not operate within ten feet of the rear of the wall. • Erosion protection shall be provided before, during, and after construction to protect washout of footing and rear of wall/grid until curbs and paving are in and vegetation is established. • Storm water shall be managed such that no water is directed at the back or front of the wall, especially before the storm sewer system is fully operational. • No utilities shall be installed within the grid zone without approval from the engineer • No excavations shall be made within five feet of the bottom of wall and should not be deeper than 1:1 from the toe of wall. For example, if the grade in front of the wall is relatively flat, then excavation five foot from wall face should not be deeper than five feet (please contact us for further explanation if needed) • Fence installers shall take care to not damage the fabric or geogrids or move the wall during their operations. There shall never be an auger used to penetrate geogrid or filter fabric for fencing or any other reason. • Curb excavation shall not cut through the filter fabric or geogrids without written approval of the wall engineer. • Paving operations shall work in a manner to not exceed the ultimate design surcharge loading or move or damage the wall. • Remove plants growing on or near the walls because roots can penetrate and destabilize the structure. • Keep the area around the wall clear of grass and weeds to prevent root damage and ensure good visibility for inspections. • Fill small cracks with appropriate sealant to prevent water infiltration. • Consult a professional for significant cracks as they might indicate structural issues. • Ensure that drainage pipes and weep holes are clear of debris and functioning properly to prevent water pressure build-up behind the wall. • Direct surface runoff away from the retaining wall using gutters, downspouts, and proper grading. • Maintain a consistent water level in the pond to prevent undue pressure on the retaining wall. • Regular professional assessments are also recommended to ensure the wall's stability and longevity. ROSCH will be happy to facilitate an on -site meeting between your and ROSCH's field staff to answer any questions. Respectfully Submitted, Rosch Southwest, LLC Richard Jen ins,P.E.

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.
