This scope of service will be performed under an amendment to the Work Order issued in accordance with the Professional Service Agreement No. 8497 for Stormwater Consulting Engineering Services, dated September 25, 2017. This scope of work is Amendment 1 to Work Order Number: TRB-2020-01. The Professional’s services for the project are detailed hereinafter. Project Objective: Update the alternatives analysis and selected plan for the Canal Importation Basin Master Plan including the Manchester Scarborough flow path. It is understood that the City will designate Mr. Theodore Bender as the City’s Project Manager (City’s PM). Mr. Theodore Bender will be the City’s primary point of contact with respect to the work performed under this AGREEMENT, with authority to transmit instructions, receive information, and interpret and define City policies and decisions relative to elements pertinent to the work covered by this AGREEMENT. The Canal Importation Basin is a five square mile basin located in west-central Fort Collins with three major irrigation canals traversing the basin from north to south (Pleasant Valley and Lake Canal, New Mercer Ditch, and Larimer County Canal No. 2). The canals intercept runoff within the basin and transport it out of the basin and also spill runoff into the basin where the canals are capacity limited. The Canal Importation Basin has a long history of flooding including storm events in 1938, 1975, 1992, and 1997. The most recent drainage basin master plan for the Canal Importation Basin was completed in 2001 with updates to the hydraulics and hydrology completed in 2014. There are five primary flow paths within the Canal Importation Basin conveying flows from west to east to the Old Town Basin and Spring Creek Basin: 1. Mulberry Street Flow Path 2. Plum Street Channel 3. Clearview Channel 4. Canal Importation Channel 5. Elizabeth Street Channel The scope of work for this master plan update is to update the Alternatives Analysis and Conceptual Design using the 2014 updates to the hydraulics and hydrology, account for any constructed improvements, consider current design practices, and evaluate the basin in a more holistic approach including parks, trails, nature areas, and water quality opportunities. DocuSign Envelope ID: FC2CB7DE-59A3-4126-B6CF-376917FBABB2 PAGE 2 OF 6 Figure 1: Canal Importation Basin The Manchester Scarborough flow path was not included in the 2014 hydrologic or hydraulic updates for the Canal Importation Basin, and was not included in the scope of work contracted as Work Order Number: TRB-2020-01. This amendment adds alternatives analysis and development of a selected plan for the Manchester Scarborough flow path. Task 1 – Project Management and Meetings Professional’s Project Manager (Professional’s PM) will manage the scope, schedule, and budget, and keep the City’s PM informed throughout the project. Professional’s PM will prepare and submit monthly an invoice for services performed and a brief status report. The report will include a narrative description of progress to-date, actual costs for each Task, estimates of percent complete, and potential cost variances. The following subtasks are also included in this task. • Work Order Number: TRB-2020-01 included a total of 7 monthly meetings. This amendment adds one additional monthly meeting. It was also assumed that the project would be completed over a 6 month period. This amendment adds 5 months to the overall schedule for a total of 11 months. • Project coordination with subcontractors. Deliverables: • Monthly invoice and status report. • Prepare and submit brief meeting minutes that summarize key decisions and action items in electronic format. Develop a log of key decisions and action items. Assumptions: • Project coordination meetings will be held virtually. • It is assumed that the project will be completed by December 31, 2020. Task 2 – Data Collection and Review Professional will review data provided by the City for the Manchester Scarborough flow path including, but not limited to the following documents: DocuSign Envelope ID: FC2CB7DE-59A3-4126-B6CF-376917FBABB2 PAGE 3 OF 6 • Canal Importation Basin Master Drainage Plan, Anderson Consulting Engineers, Inc., 2001. • West Vine Unsteady Canal HEC-RAS Model. • City of Fort Collins GIS Data including parcels, right-of-way, and utilities. • Existing LiDAR topography. • City of Fort Collins Trail Master Plan. • City of Fort Collins Nature in the City Program. Professional will also perform a site visit to review the current site conditions, the improvements proposed in the current drainage master plan, and evaluate opportunities for enhancements to the basin including water quality, open space and natural areas, parks, trails, and habitat. Deliverables: • There are no deliverables associated with this task. Assumptions: • Existing conditions hydrologic modeling has been completed and is not required for this alternatives analysis. Task 3 – Review of Current Hydrologic Model and Canal HEC-RAS Model Professional will perform a due diligence review of the current hydrologic model and the unsteady HEC-RAS model for the PV&L Canal. Professional will coordinate any suggested revisions with the City and revise the models, as necessary. Per coordination with City staff, Professional will add existing storm pipes 24” in diameter and larger to the existing conditions hydrologic model. Professional will also sub divide existing basins to approximately 25 to 30 acres in size. This revised model will be the baseline model for the alternatives analysis. Deliverables: • Update to Technical Memorandum summarizing any changes to the current hydrologic model. • Revised hydrologic model including existing storm drains 24” in diameter and larger and sub divided basins. Assumptions: • The Hydrologic and Hydraulic Model Review Summary dated June 18, 2020 will be updated to include discussion related to the Manchester Scarborough flow path. • The existing 2017 City of Fort Collins rain on grid analysis will be used to locate basin design points when sub dividing the basins. Task 4 – Alternatives Analysis For the Manchester Scarborough flow path, Professional will utilize the previously completed Master Drainage Plan and updates to the Master Drainage Plan, information collected through site visits, and information collected through coordination with the City to develop alternative drainageway plans in GIS to address problem areas within the basin. Problem areas include flooding issues (structures, major roads, and critical facilities), undersized infrastructure, channel or bank instability for open channels, interaction between drainage features and the canals within the basin, DocuSign Envelope ID: FC2CB7DE-59A3-4126-B6CF-376917FBABB2 PAGE 4 OF 6 and ecological issues. The alternatives analysis will also include opportunities for water quality enhancement along the flow path. The alternative improvements will focus on new storm sewer pipe systems, the existing detention pond upstream of Taft Hill Road, and the existing detention pond west of the PV&L Canal. Professional will also perform the following tasks: • Identify problem areas for the 100-year flood event. • Evaluate up to two alternatives for the Manchester Scarborough flow path. The two alternatives are assumed to be a detention option and a conveyance option. The detention option will focus on maximizing detention along the flow path. The conveyance option will focus on increasing the conveyance capacity of open channel and pipe systems with no or limited detention. • Develop alternative hydrologic models to model the alternative improvements. • Evaluate water quality opportunities within the basin including those identified as part of the 2001 master plan. • Develop a recommended plan for review by the City PM and other City staff. • Determine sizing for proposed improvements including pipes and detention and water quality facilities. • Determine right-of-way required for each alternative.
