The land scape plan,the retaining wall site plan and the grading plan do not match. The grading plan depicts <br /> two long retaining walls. The landscape plan depicts two short walls. The Site plan from Civil Design depicts 1 <br /> long wall and 2 short walls. All three plans should reflect the same retaining walls. <br /> Please also note that Bob Bean completed a review of the raingarden and provided that input back to Mike. Copied <br /> below. <br /> Mike, <br /> 1 have completed review of the information submitted. Following are my comments for your consideration: <br /> 1. The rain garden has been adequately sized to maintain proposed peak runoff rates below existing <br /> conditions and retain a volume on site equal to 1" over the new impervious surfaces. <br /> 2. The rain garden should not be constructed until the upstream areas have been permanently stabilized. <br /> 3. The installation of the rain garden should be inspected by the City to ensure it is constructed as <br /> proposed. <br /> 4. A record survey of the rain garden should be provided after it is completed to ensure adequate volume <br /> is provided to meet requirements. <br /> If you have any questions or comments, please contact me to discuss. <br /> Thanks, <br /> Robert E.
