1 Thornton Water Project Larimer County Route Study and Project Update September 12, 2017

2 Purpose of Meeting Provide information on the Thornton Water Project Present the results of the pipeline routing study Get input and answer questions from communities

3 Odds and Ends Food and drink are available enjoy! Please save questions for the discussion after the brief presentation Allow time to review Project boards and talk one-on-one with our Project staff Sign up for Project updates if you are not already

4 Refresher Building a water pipeline from WSSC Reservoir #4 to Thornton to use the water the city has owned for over 30 yrs. Purpose: Provide supply for Thornton s future Provide quality water to Thornton s residents Additional, diverse source to maintain drought resiliency Water available by 2025

5 Outreach to Date Public meetings (2 in Larimer Co, not including tonight) Small group meetings with HOAs, neighborhoods, residents Consultations with governmental agencies including Fort Collins, Larimer County, CSU, CDOT, etc. One-on-one phone calls with homeowners

6 Input Received Open House and HOA input: Look at alternative routes, including use of County roads, WSSC property Project Team spent the summer identifying and evaluating potential alternative routes, and talking to County staff Additional route alternatives necessitated informing additional areas

7 Meeting Notification Area

8 Location/Route Selection Identify potential routes Evaluate routes against criteria Properties Environment Traffic Noise/Vibration Cost

9 Potential Route Segments

10 Route Identification Select equivalent Segments with lower community impact All Alternatives withdraw from WSSC Reservoir #4 Comparable effect on WSSC reservoirs Consistent with Project requirements Use WSSC property where available Use County Road Rights of Way where appropriate

11 Looked at Ten Potential Routes Three North routes that go north of Eagle Lakes subdivision and then east on County Road 56 Two West routes that go to the west side of WSSC #4 and connect to North routes

12 Potential Routes (Cont.) One Central route that goes east through Eagle Lake and Woody Creek areas and then east along Evans/Bold Venture/Grey Rockroad alignment Four South routes that go east from WSSC #4 along Douglas Road; two in the roadway, two outside the right of way

13 North 1 Main pump station east of WSSC #3 Smaller pump station south of WSSC #3 dam First portion of route on WSSC property Use CR 56

14 North 2 Pump station south of WSSC #3 dam Pipeline route north of Eagle Lake area Use CR 56

15 North 3 Pump station east of WSSC #3 Pipeline route north of Eagle Lake area Use CR 56

16 Central Pump station south of WSSC #4 dam First portion of route though Eagle Lake, Woody Creek areas Along Evans/Bold Venture/Grey Rock road alignment Use Thornton property to CR 56

17 West 1 Pump station on WSSC Kluver Reservoir property Pipeline route between WSSC #3 and #4 Pipeline route north of Eagle Lake area Use CR 56

18 West 2 Pump station south of WSSC #4 dam Pipeline route in Val Vista Dr, then between WSSC #3 and #4 Pipeline route north of Eagle Lake area Use CR 56

19 South 1 Pump station between WSSC #4 dam and Douglas Rd. Pipeline outside Douglas Road to Turnberry Use Thornton property to CR 56

20 South 2 Pump station between WSSC #4 dam and Douglas Rd. Pipeline in Douglas Road to Turnberry Use Thornton property to CR 56

21 South 3 Pump station between WSSC #4 dam and Douglas Rd. Pipeline outside Douglas Road to ½ mile east of Hwy 1 North to Grey Rock/Bold Venture road alignment Use Thornton Property to CR 56

22 South 4 Pump station between WSSC #4 dam and Douglas Rd. Pipeline in Douglas Road to ½ mile east of Hwy 1 North to Grey Rock/Bold Venture road alignment Use Thornton Property to CR 56

23 Evaluation Criteria Considerations from Operations Residential Pump Station Visual/Noise/Vibration TWP Operations Considerations from Construction Traffic Environmental Opportunity for coordinated projects

24 Evaluation Criteria Summary for Larimer County Pipeline Routing Study Criterion Method of Measurement Data Source Considerations From Operations Residential Estimated number of homes within the 500 foot wide strip where pipeline is located within an easement (does not include pipe in ROW, WSSC or Thornton owned property). National Agricultural Imagery Program 2015 and Google Imagery 2016 Pump Station Visual/Noise/ Vibration Visual: Estimated number of homes within ½ mile of pump station with probable line of sight. Noise and Vibration: Estimated number of homes within 250 feet of pump station score 3, within feet score 2, within 501 1,000 feet score 1. National Agricultural Imagery Program 2015 and Google Imagery 2016 TWP Operations Estimated length of road within a residential area required to drive to access pump station plus length of easement on private property. Considerations From Construction Activities Traffic Estimated number of construction days within ROW multiplied by average daily traffic volume. Estimated number of construction days adjacent to ROW multiplied by 25% of the average daily traffic volume. National Agricultural Imagery Program 2015 and Google Imagery 2016 Traffic count information from Larimer County Road Information Locator GIS; Estimated per ITE Trip Generator Manual Environmental Coordinated Projects Opportunity Estimated areas crossed identified as riparian and/or populated with trees. Shared length of possible coordinated projects to minimize community impacts Riparian data from the Colorado Natural Heritage Program GIS information and National Agricultural Imagery Program 2015 and Google Imagery 2016 Discussions with Larimer County and Northern Water

25 Routing Study Results

26 Preferred Route South 2

27 Preferred Route South 2 In Douglas Road from Bayshore Rd to Turnberry Rd, then on Thornton property Minimizes number of private properties crossed Potential cooperative project with Larimer County, others efficient use of taxpayer dollars

28 POTENTIAL PIPELINE ROUTES IN ROAD RIGHT-OF-WAY

29 Roadways & Utilities Public Utilities are Commonly Located in Roadway Rights-of-Way Underground (water, sewer, natural gas) Above ground (electric, etc.) Thornton Pipeline Alternatives Consider Various Right-of-Way Segments Various Subdivision Roads CR 56 CR 54 Douglas Road

30 Pipeline Route» Thornton s analysis indicates South 2 Route to be Preferred Route» South 2 - Locates the pipeline within Douglas Road (CR 54) right-of-way» From Bayshore Road to Turnberry Road» Turns North onto Thornton Property

31 Current Conditions Douglas Road» Needs Maintenance» Pavement Condition Index (0 100 scale)» CR 54 west of SH 1 PCI = 65» CR 54 east of SH 1 PCI = 51

32 Current Conditions Douglas Road» CR 54 an overlay candidate» When you overlay a roadway, current width and geometry remains relatively unchanged for the foreseeable future

33 Improvement Needs Douglas Road» Traffic signal at Douglas / State Highway 1» Address intersection safety and capacity» Grant funds 2020 design / 2021 construction» Trying to get this advanced in time» Shoulders to support bicyclists, etc.» Turn lanes for both safety and capacity» Neighborhood street intersections» Driveways

34 Transportation Master Plan

35 Reconstruct Douglas Road Shields to Hwy 1

36 Considerations» Routing through public right-of-way versus easements through private property» Is there an opportunity to leverage funding and make transportation improvements that address both current and future needs?» Schedule / Timing» Duration of Construction

37 Other Potential Project Coordination Local Utilities Coordination to replace aging infrastructure Northern Water s NISP Pipeline Continue discussions

38 Next Steps Finalize TWP 1041 permit application and deliver draft to Larimer County Planning for pre-completeness review Revise application if needed and submit final application Larimer County 1041 Permit process including: Planning Commission Hearings Board of County Commissioner Hearings

39 Permit Application Corridor The 1041 Permit application will include a 500 ft. wide corridor along Douglas Rd.

40 Permitting after ROW Acquisition In Weld County
