MR 7: Flow Control <br /> Flow control is provided in accordance with public works policy#2-11. This policy <br /> requires matching the existing conditions runoff rate. The modeling shows that 100' of <br /> equivalent length 3' diameter pipe is sufficient for this task. Three 60"manholes are <br /> shown on the plans,the equivalent volume is used to reduce the 100' that is shown in the <br /> modeling. <br /> MR 8: Wetlands Protection <br /> There are no wetlands on or in the vicinity of the project site. The site is located in a <br /> developed urban area. <br /> MR 9: Operation and Maintenance <br /> The building's maintenance staff will be charged with monitoring the function of the on- <br /> site drainage facilities. If the final drainage design includes elements for which the <br /> Department of Ecology has identified maintenance guidelines, an Operations& <br /> Maintenance Manual is placed in Appendix E. <br /> 1 <br /> I <br /> 1 <br /> I <br /> 1 <br /> p <br /> I <br /> I <br /> Hopeworks II DCI Engineers Page 6 <br /> Storm Drainage Report <br />
