Explanation

 

1. BACKGROUND: The City of Columbus Division of Sewerage and Drainage (DOSD) initiated the Plum Ridge Integrated Solutions (CIP 650870-158191) and Plum Ridge Storm Sewer Improvements Project (CIP 611714-100000) to perform the investigation, evaluation, formulation and design work necessary to prepare construction documents for: mitigation of stormwater flooding by improving the existing stormwater system within the project area(s) and the use of integrated solutions to improve water quantity and water quality within the project area(s).  This work performed under phase 1 will be in preparation of the future remediation of inflow and infiltration (I/I) within the project area(s).  

 

2. PROCUREMENT: The Department of Public Utilities advertised a Request for Proposals (RFP’s) on August 29, 2019 through September 27, 2019 pursuant to the overall requirements of City Code Section 329 in order to solicit proposals for the project. Five (5) proposals were received and reviewed, and it was determined that Evans Mechwart Hambleton & Tilton Inc. dba EMH&T best meets the needs of the Department of Public Utilities.

3.   SUMMARY OF TASKS:  The scope of work for this project includes condition assessment and cleaning of the existing storm sewers and performing inspections of all storm manholes within the project limits to assist in the development of an accurate stormwater hydraulic model, and to assess the structural integrity of the existing storm sewer system prior to evaluating any potential integrated solutions necessary to accomplish the objectives of Blueprint Columbus.

 

The scope of work shall also include the use of the aforementioned stormwater hydraulic model to determine the hydraulic performance of the existing storm sewer system, and to evaluate potential improvements to this system through replacement of existing infrastructure or the installation of new facilities prior to evaluating any potential integrated solutions necessary to accomplish the objectives of Blueprint Columbus.

 

The scope of work shall also include performing all requisite investigation, evaluation, formulation and design work to prepare construction documents for the remediation of inflow and infiltration (I/I),  and the improvement of water quantity and water quality within the project area(s) using integrated solutions.  The City envisions that the Blueprint Columbus integrated solutions approach shall focus on removing sufficient amounts of I/I and providing positive treatment of stormwater with green infrastructure prior to its discharge into storm sewers and/or receiving water bodies.  It is the objective of the City to mitigate overflows of the area’s designed sanitary relief structures (DSRs) to the 10-year level of service.  All extensive computer-based modeling required to evaluate this criteria in the sanitary system shall be performed by the City and not be a part of the scope of these services. In order to determine water-quality and quantity benefits to the City’s MS4 discharges, stormwater modeling services shall be performed as a task under these contracts.

 

 

4.   MULTI-YEAR CONTRACT: The Department anticipates requesting additional future modifications to this contract.

 

5.  PROJECT TIMELINE: This project is planned for approximately five (5) years, completing in December 2025.

 

6.   Contract Compliance No.:  31-0685594 | MAJ | 1/19/2020 | Vendor#: 004214

 

7.   Emergency Designation:  Emergency legislation is not requested at this time.

 

8. Economic Impact: The City has embarked upon its approved Wet-Weather Management Plan (WWMP).  Currently, that plan is almost entirely comprised of a series of treatment plant capacity upgrades, storage tanks, tunnels, and other piping system augmentations; collectively known as “gray” infrastructure.  After approval of the WWMP,  the use of more renewable, sustainable, and environmentally friendly systems, commonly referred to as “green” infrastructure, has been recognized and implemented in many communities as a potential solution to many of the elements associated with consent order requirements.

 

It is anticipated there will be a greater impact to both economic impact and advantages by implementing a group of smaller projects which would be conducive for competition with local suppliers and vendors as opposed to the large scale, previously devised, WWMP projects. 

 

Community and Outreach for the project will be conducted by the City, the selected consultant and the Public Outreach Consultant, RAMA Consulting, which is currently under contract for this work. 

 

9.   Fiscal Impact: A transfer within and expenditure of up to $211,691.94 from the Storm Sewer Bond Fund 6204 is necessary; an expenditure of up to $583,163.68 from the Sanitary Sewer General Obligation Bond Fund 6109 is needed; and an amendment to the 2019 Capital Improvement Budget is necessary to provide sufficient authority.
