Revise for consistency. 2.3.1 Proposed Basin PR:1A Proposed basin PR:1A is comprised of the first floor entrance roof. The roof discharges to Pipe C1. The basin area totals 79 sf and is 100% impervious. Based on a flow path of 9.5 feet at a slope of 2%, the time of concentration is 5 minutes. The resulting 100-year flowrate is 0.011 cfs. PR:1A is collected and directed to a pervious paver system via Pipes C and A in order to provide WQCV. 2.3.1 Proposed Basin PR:1B Proposed basin PR:1B is comprised of the second and third floor stair and deck areas. The roof dis- charges to Pipe C2. The basin area totals 141 sf and is 100% impervious. Based on a flow path of 11.2 feet at a slope of 2%, the time of concentration is 5 minutes.

During the excavation process, material should not be left between the excavation face and the grout/micropile column. 4.4 The micropile wall designs are valid only for dry surface and subsurface conditions. If surface water or groundwater is encountered during excavation or installation, RJ Engineering should be notified immediately and the wall may be redesigned at the discretion of RJ Engineering. Surface and subsurface drainage from adjacent properties should not be discharged at the top or through the micropile wall. Saturated soils may result in materials piping out from between micropiles resulting in failure and/or excessive wall movements. 4.5 The design life on this micropile wall is 12 weeks. Design life is defined by the beginning of excavation to the construction of the foundation wall. If the duration of the project exceeds the 12 week duration, RJ Engineering shall be contacted to evaluate the performance of the system and determine if the design life can be extended. 4.6 RJ Engineering is not responsible for maintaining slope stability above and below the micropile wall during construction. 4.7 Existing utilities appear to be in conflict with proposed shoring wall location. Utility locations presented shall be field verified and exposed or abandoned prior to micropile wall installation. 4.8 RJ Engineering is not responsible for quality control, quality assurance, changed conditions or problems resulting from improper construction techniques. 4.9 RJ Engineering is not responsible for construction site safety. 4.10 RJ Engineering is not responsible for wall layout.
