Technical Questions and Answers #1 Request for Qualifications – Cody Storm Drainage Master Plan and Rate Setting Study November 15, 2022 Question: There have been general questions about the interaction of the City’s storm drainage system and local irrigation canal and ditch facilities—and if analysis of this interaction will be part of the Master Plan surface flow modeling. Answer: There is known interaction and connectivity between the City’s storm drainage system and irrigation facilities including canals and ditches, and the Storm Drainage Master Plan modeling will be a tool to better understand this connectivity. It is anticipated that Phase 1 of the project will include meetings with City of Cody, Cody Canal and Irrigation District (CCID), and consultant staff to: 1) identify and investigate problem areas where significant amounts of storm runoff enter the CCID facilities; and 2) identify areas where storm runoff contributes to and/or causes overtopping of CCID canals and ditches during rainfall events. It is also anticipated that later phases of the project (specifically surface flow modeling) will include work to quantify the impacts of storm runoff on CCID facilities, as well as possible improvements to the storm drainage system that will minimize and reduce the amount of storm runoff entering the CCID facilities.
