Respectfully submitted, Cathy Burrage Recording Secretary I -3 COUNCIL COMMUNICATION Date Agenda Item Subject June 1, 2015 B ig Dry Creek Diversion INITIATED BY Utilities Department STAFF SOURCE Stewart Fonda , Director of Util ities COUNCIL GOAL AND PREVIOUS COUNCIL ACTION None RECOMMENDED ACTION The Englewood Water and Sewer Board , at their April 14 , 2015 meeting , recommended Council approval , by Ord inance , of the contract w ith Mclaughlin Whitewater Design Group. BACKGROUND, ANALYSIS, AND ALTERNATIVES IDENTIFIED Big Dry Creek discharges into the S. Platte River about 300 yards above the wate r intake at the Union Ave . Pump Station . The Big Dry Creek project would give the option of allowing water to bypass the intake structure. This bypass would alleviate hardness issues during low flow periods in the river. A structure for this purpose had existed but was destroyed during the 1965 flood. The proposed contract authorizes Mclaughlin Whitewater Design Group to perform Alternative Analysis, Preliminary Des ign and Spec ial Services. The Special Services include base mapping and support during the preliminary permitting process with the U .S . Army Corp of Engineers. FINANCIAL IMPACT The contract amount is $78 ,435 .00. The full contract amount will be funded from the $600 ,000 received from the Denver Water Boa rd Settlement. The settlement st ipulates that the funds be dedicated to alleviating water hardness at the Allen Water Treatment Plant.

City of Englewood Utilities Department 1000 Englewood Parkway Englewood, CO 80110 RE: Professional Services Proposal Big Dry Creek Diversion Replacement -Englewood Colorado Dear Mr. Brennan: Mclaughlin Whitewater Design Group (MWDG}, a Division of Merrick & Company, is submitting this scope of work and budget to complete professional services for the above referenced project . The work will include Alternatives Analysis, Preliminary Design and Special Services. MWDG is proposing to team with ERO (permitti ng} and Aztec Survey (mapping}. BACKGROUND A major flood in 1965 caused w ide-spread damage along the South Platte River. Englewood 's diversion structure at the confluence of Big Dry Creek and South Platte River was destroyed . MWDG met with you and Dave Coffman on site on February 10t h to discuss the replacement of the diversion. Project purpose and objectives discussed: • Purpose: Improve raw water quality at Englewood's primary drinking water intake on the South Platte River at Union Avenue. Water quality, particularly Hardness, in Big Dry Creek is poor creating treatment issues. • Objective: Divert flows from Big Dry Creek (approximately 5 cfs} year-round and discharge below primary drinking water intake at Union Avenue . Additional items discussed included: • The City has contact the USACE regarding CWA 404 permitting. The USACE indicated that a permit will likely be required and suggested the City work with a permitting specialist . • Flood Conveyance -FEMA Flood Hazard Zones have been mapped on Big Dry Creek. MWDG anticipates that the proposed project will need to meet "no-rise" criteria. MeLoughlin Whitewater Design Group. 2420 Alc ott St re e t. De nv er.

MWDG suggests that UDFCD be approached for possible partnering and integration of master plan improvements with diversion work. • Hardness not from an iden tified po i nt source -likely from soil exfiltration throughout basin and urbani zation. • There are no water users b etween the confluence and proposed d ischa rge locatio n besides Eng lewood . SCOPE Professional services scope of work has been divided into Special Services and Preliminary Design. Special Services Task 1: Permitting Support MWDG and design team {ERO) will provide the City support during the preliminary permitting process for the following permits during this phase of work: • CWA Section 404 -MWDG will support ERO's {subconsultant to MWDG) 404 permitting effort by providing project information, such as narratives of project purpose and improvements, sketches, and assistance with in itial consult with USACE. Initial meetings will be held with the USACE. A permitting strategy will be developed based on information gathered and consult with USACE. Final permitting including formal applications would be completed in a future phase {Final Design). Specific tasks that will be completed for CWA permitting are as follows: o Wetland Delineation o Endangered Species Act Compliance o Meetings with Regulators o Prepare Pre-construction Notification to the USACE o Prepare Hydrologic Depletions Analysis o Project Coordination • Floodplain -MWDG will coordinate with the City's Floodplain administrator Allen White to determine required permitting and analysis. Refer to Attachment C for the detai led permitting tasks and del iverables for the CWA 404 perm it {ERO 's scope). Deliverables : 1. Coordinate, prepare for, and attend one meeting with USA CE w/ meeting notes. 2-3 2. Support Documents 404 Permits (for ERO) -project descriptions, write-ups, sketches, assistance with initial consult with USACE 3. See Attachment Cfor additional CWA 404 deliverables . 4. Coordinate, prepare for, and attend one meeting with Englewood Floodplain Administrator w/ meeting notes. Task 2: Stakeholder/Owner Engagement It appears there are three primary Owners/Stakeholders in the project area -South Suburban Parks and Recreation District (trail/bridge at Big Dry Creek), Colorado Water Conservation Board (River Owner), and Urban Drainage and Flood Control District MWDG would coordinate and attend three meetings with these entities to present the proposed project. Meeting objectives would include identifying partnering opportunities, ownership/easements, and any project requirements. Deliverables: 1. Attendance at three {3} Stakeholder/Owner meetings. 2. Meeting materials (e.g. Power Point presentations, sketch/drawings) 3. Meeting notes Task 3: Base Mapping MWDG will complete topographic and bathymetric survey for the creek bottom, banks, and top of banks from the confluence with South Platte River to east side of Sante Fe Boulevard. Detailed ground survey will be conducted in diversion area. Cross sections at approximately 200 foot intervals will be surveyed along the creek upstream of the project area for flood and hydraulic analysis. MWDG completed survey work as part of the River Run Park project. Mapping from that project will be combined with new mapping for a complete base map for the project. Control points will be set . A private utility locate service will be h i red to "paint" existing utilities for survey. Englewood to provide MWDG any available utility information in the project area. Potholing of utilities will be completed by the City as needed based on preferred alternative. Property ownership and easement research will be conducted by a title search with limited field survey work to delineate approximate property lines and easements for design purposes . In areas where research indicates property lines are close to improvements or construction access will be needed additional field work may be added by the City to more accurately locate property lines. Easements and property lines will be added to base mapping. Deliverables: -Site Base Map w/ Property Lines & Easements (approximate) 2 -'-/ Preliminary Design Phase Two concept alternatives will be developed for the diversion and conveyance systems. Preliminary design will be completed for the City selected alternative . The following tasks will be completed for this phase Task 4: Coordination Meetings Conduct meetings with City of Englewood during preliminary design phase for coordination and review. Meetings will focus on project requirements, operations, proposed designs, utility conflicts, permitting and approval processes . Deliverables : 1. Conduct three {3} meetings 2. Meeting Agendas & Minutes Task 5: Flood Analysis The project requires a flood submittal and analyses. Proposed improvements that could affect flood conveyance including diversion and intake structure will be analyzed . One dimensional hydraulic modeling will be performed using HEC-RAS software. A Flood Insurance Study has been completed by FEMA along Big Dry Creek. It is assumed that the City has the Effective FEMA HEC-RAS model in electronic form and that no significant changes within the reach have been made since the effective date (i.e. Existing and Corrected Effective Models are the same). MWDG will perform the flood analysis using this model. Deliverables: 1. Flood Analysis including a no -rise certification per FEMA requirements . A CLOMR or LOMR is not included. Task 6: Diversion Hydraulic Analysis The hydraulic analysis will entail closed conduit hydraulics of the diversion piping, analysis of the intake and bar rack. This will establish the required control section elevations. The low-flow hydraulics of the main channel structure including low flow notch and control section will then be conducted. Deliverables: 1 . None (analysis summary and results included in Task 8} Task 7: Alternative Concepts It is anticipated that the general layout and alignment of the drop structure and pipeline will present no significant alternates or options. These will be developed to a schematic z -S level in this Task to support the development/selection of the intake design. Two alternatives are anticipated for the intake -a side spill with fixed crest control and an intake with an inline gate or adjustable cres t control. Deliverables: Concept Drawings (Hardcopies {3}, Electronic files (PDFs)) -Total Estimated Sheets:~ -Diversion & Intake Plans: 2 -Plan & Profiles: 1 Task 8: Preliminary Design The alternative selected by the City will be further developed to a preliminary design level. The designs will integrate with improvements currently being planned along this reach by MWDG. The drawings will be created in AutoCAD using MWDG's standard format. A technical memorandum will be written and include the basis of design, recommendations for final design, and an opinion of probable cost . Deliverables: 1. Preliminary Drawings {Hardcopies (3), Electronic files (PDFs}) -Total Estimated Sheets:~ -Diversion & Intake Plan: 1 -Plan & Profile: 1 -Detail Sheets: 1 2 . Engineer's Opinion of Probable Costs 3.

The proposed project will require impacts to wetlands and other waters of the U.S along Big Dry Creek. Based on preliminary project information, it is likely Section 404 of the Clean Water Act authorization from the U.S. Army Corps of Engineers (Corps) is required. ERO will perfom1 the following tasks to assist the Client with Section 404 pem1itting. Task 1: Wetland Delineation ERO Resources will evaluate the overlook project area for wetlands or other potential waters of the U.S. Areas \\·ith wetland indicator species will be investigated for soil and hydrologic indicators . Wetlands will be delineated following the methods in the revised online version of Corps· Wetland Delineation Manual (1987) and appropriate regional supplement. Open water and channels will be dctemiined based on the presence of an ordinary high water mark as defined in 33 CFR Part 328. The boundaries of wetlands, open water, and channels will be mapped to sub-meter accuracy by ERO using a Global Positioning System (GPS). or, when appropriate, boundaries will be mapped onto an appropriately-scaled aerial photograph . ERO will incorporate the wetland boundaries into project base mapping provided by the Client and will send the Client a revised base mapping file that includes a layer with the boundaries of wetlands, open water, and channels.
