This request invites qualified consultants to submit proposals for accomplishments of the items of work described below under Scope of Services. Proposals shall be prepared and submitted in accordance with the requirements described in this Request for Proposals (RFP). Once the firm is selected, a contract will be negotiated based on a mutually agreed upon scope of services. 2. Project Description: The City is completing an assessment of the Des Moines Downtown Levee Systems (DM-I, DM-II, and DM-III) relative to Federal Emergency Management Agency accreditation requirements (44 CFR 65.10). The City s consulting engineer for the assessment, Stantec Consulting Services Inc. (Stantec), issued a draft report titled Des Moines Downtown Levee Systems Assessment Overview dated March 19, 2015 that outlines a program of projects to both reduce flood risk and bring the levee systems into compliance with 44 CFR One component of the plan includes improvements to the stormwater pump stations along the DM-I, DM-II and DM-III levee systems. Stantec prepared the Des Moines Downtown Levees Stormwater Pump Station Assessment Report dated March 8, 2016 (available on the City s Professional Service RFPs website) that identified improvements necessary to meet FEMA criteria and reduce flood risk associated with the pump stations. This report identified the following pump stations needing replacement: A. E 1 st Street & E Market Street Stormwater Pump Station Most of the equipment for the existing E 1 st Street and E Market Street pump station is nearing the end of its functional lifespan. The extensive costs to repair several items, including structural cracking in the perimeter wall, and make operational improvements, all while keeping the pump station in service during the repairs, justify complete replacement of this pump station. There is potential real estate available immediately north of the existing pump station, pending no groundwater contamination exists on the site. This project includes replacement of the existing E 1 st Street and E Market Street pump station and performing storm sewer improvements along E. 4 th

2 Street. Attachment 2A and the Des Moines Downtown Levees Stormwater Pump Station Assessment Report contain more information on this project. B. SE 9 th Street Stormwater Pump Station The existing SE 9 th Street pump station has inadequate discharge elevation (3-feet lower than required for FEMA accreditation), lacks redundancy, has insufficient capacity, and needs several operational improvements and repairs. There is real estate available to construct a new pump station northwest of the existing pump station. This project includes replacement of the existing SE 9 th Street pump station. This project also includes upsizing the storm sewer trunk sewer along Maury Street between SE 11 th Street and SE 9 th Street. Attachment 2B and the Des Moines Downtown Levees Stormwater Pump Station Assessment Report contain more information on this project. C. SE 1 st Street & Van Buren Street / SE 4 th Street & Van Buren Street Stormwater Pump Stations The existing SE 1 st Street & Van Buren Street pump station has inadequate discharge elevation (7-feet lower than required for FEMA accreditation) and needs several operational improvements and repairs. The existing SE 4 th Street & Van Buren Street pump station needs some operational improvements and modeling indicates a great deal of upstream flooding. This project includes the following scope of improvements: Constructing a new pump station to replace the SE 1st & Van Buren and SE 4th & Van Buren pump stations. There potentially is real estate available to construct a new pump station at SE 3 rd Street & Van Buren Street. Converting the SE 1st & Van Buren pump station to a gravity drain. Installing a storm sewer trunk line between Scott Avenue and SE 3rd street. Decommissioning and converting the SE 4th & Van Buren pump station to a gravity drain. Installing a storm sewer discharge between SE 8th Street and Jackson Basin.

Proposals Not Confidential: Proposer Requests for Confidentiality Under Iowa Open Records Law, Chapter 22 of Iowa Code; Disclosure of Proposal Content: Under Chapter 22 of the Iowa Code, Examination of Public Records, all records of a governmental body are presumed to be public records, open to inspection by members of the public. Section 22.7 of the Iowa Code sets forth a number of exceptions to that general rule, establishing several categories of confidential records. Under this provision, confidential records are to be kept confidential, unless otherwise ordered by a court, by the lawful custodian of the records, or by another person duly authorized to release such information. Among the public records which are considered confidential under this Iowa Code provision, are the following: 3. Trade secrets which are recognized and protected as such by law. 6. Reports to governmental agencies which, if released, would give advantage to competitors and serve no public purpose. Under Chapter 22 of the Iowa Code, the City, as custodian of the proposal submitted in response to a Request for Proposals, may, but is not required, to keep portions of such proposals confidential under exceptions 3. and 6. (noted above). If a responding individual or company in good-faith reasonably determines that a portion or portions of its proposal constitute a trade secret, or should otherwise be kept confidential to avoid giving advantage to competitors, a confidentiality request may be submitted with the proposal identifying which portion or portions of the proposal or bid should be kept confidential and why. The burden will be on each individual proposer to make such confidentiality request and to justify application of a confidentiality exception to its proposal. The City will not under any circumstance consider the entire proposal to be a confidential record. If a request is thereafter made by a member of the public to examine a proposal including the portion or portions thereof for which a confidentiality request has been made, the City will so notify the proposer and will keep confidential that portion of the proposal covered by the confidentiality request,

7 pending action by the proposer requesting confidentiality to defend its request. In that notification, the proposer requesting confidentiality will be given not more than 5 calendar days within which to file suit in Polk County District Court seeking the entry of a declaratory order and/or injunction to protect and keep confidential such portion of its proposal. Absent such action by a proposer requesting confidentiality, and absent the entry of a court order declaring such portion or portions of the proposal confidential, the entire proposal will be released for public examination. Proposer shall be responsible for all costs relating to a declaratory judgment or injunctive action, including the payment of any damages assessed and attorney fees and litigation expenses awarded. If the process for selecting the best proposal includes two or more evaluation stages, in which proposals are evaluated at each stage and the field of competing proposals is reduced, all proposals submitted shall be kept confidential, pursuant to Section 22.7 of the Iowa Code, subsection 6 cited above, until completion of the final stage of the evaluation process in order to avoid giving advantage to competing proposers. Upon completion of the final stage in the evaluation process, all competing proposals shall be subject to disclosure; if not otherwise determined confidential as above provided. 21. Contract Compliance: All firms that submit proposals in response to this RFP agree to comply with the requirements of the City of Des Moines Contract Compliance Program, which is available from the City Engineer upon request or may be viewed at the following website: m(december%202012).pdf, and has been viewed by the Consultant.
