1. Environmental Assessment Public Information Meeting – September 2010 Realignment of a Portion of a Utah Lake Drainage Basin Water Delivery System (ULS) Pipeline through Provo and Orem

2. What is NEPA? National Environmental Policy Act (NEPA) of 1969 Requires that any project using federal funds must be environmentally and sociologically reviewed – Provides detailed project description – Describes multiple alternatives – Discusses existing environmental and sociological setting – Evaluates impacts on resources

3. 2004 Plan Utah Lake System Proposed Action

4. Environmental Assessment (EA) Process for Provo Realignment

5. Project History The ULS EIS was completed in September 2004. The No Action Alternative in the current EA was the preferred alternative in the EIS.

6. Current Project Process Value Engineering Study Workshop completed in December 2009 with the following recommendations – 1) Avoid the geological slide area hazards along 1450 East and Foothill Drive. – 2) Minimize the length of pipeline in 900 East and avoid the reach south of University Parkway if possible. – 3) Reduce costs by using the shortest alignment that avoids (1) and (2) concerns. – 4) Alignments evaluated in this EA are a combination of alignments recommended in the VE Study Report.

7. No Action Alignment/Geological Hazards

8. Purpose and Need Have not changed from those stated in the ULS EIS. However, the proposed realignment would: – Avoid active and historical landslides – Reduce the risk associated with geologic faults – Shorten the overall pipeline length

9. Alternative Alignments

10. Key Resources Applicable to entire alignment Specifically discussed South of 2200 North – Geologic Hazards – Traffic – Utilities – Schools and Residences

11. Alternative 1 Geologic Hazards Avoids Wasatch Fault and associated splays Geologic conditions may include liquefiable soils. Mitigation measures would be incorporated into final design and construction planning. Traffic Seven Peaks Blvd, 700 N. and 2200 N. could be closed with local access only. 900 E could be restricted to one lane in each direction. 2320 N., 700 E, and 2270 N. (Opt A) would be closed with local access only. University Ave maintain current number of lanes. Utilities 700 N. has moderate utility congestion. 900 E and 2200 N have moderate to heavy congestion Electrical transmission line may need to be relocated along 900 E. Major storm drain crossings required along 900 E at 820 N and 900 N. University Ave has minimal utility congestion. Overhead utilities include power, high-voltage power, and communication lines. Schools & Residence 3 schools (Wasatch Elementary, Rock Canyon Elementary and Centennial Middle) Brigham Young University (BYU) Impacts residential homes that front the alignment primarily along 700 N and 2200 N. The majority of the alignment is located in major collector and arterial streets (900 East and University Ave)

12. Alternative 2 Geologic Hazards Avoids the Wasatch Fault and associated splays Geologic conditions include liquefiable soils. Mitigation measures would be incorporated into final design and construction planning. Traffic Residential streets south of 4525 N would be closed with local access only. 900 E could be restricted to one lane in each direction 4525 N between Canyon Rd and University Ave would be reduced to 1 lane with flagger or automatic traffic signal. Current number of lanes would be maintained in University Avenue. Utilities 1200 E and Cherry Ln have moderate utility congestion. 2-inch gas line and short reaches of 4- and 6-inch water lines would likely be relocated. Timpview Dr and 4525 N have moderate to significant utility congestion. During construction 2-inch gas line and sections of storm drain would be relocated at Timpview Dr, portions of 15-in irrigation line would be relocated at 4525 N. University Ave has minimal utility congestion. Overhead utilities. Approx. 85% of alignment, has 10- and 6-inch parallel sewers on both sides of street (no sewer lateral crossings) Schools & Residence 3 schools (Rock Canyon Elementary, Timpview High, and Edgemont Elementary) Impacts residential homes along 1200 E, Apple Ave, Cherry Ln, Timpview Dr, and sections of 4525 N. Option alignments primarily located in residential streets.

13. Alternative 3 Geologic Hazards Crosses landslide shown on USGS map (Baker, 1964). Alignment crosses ~1,200-ft length of landslide. Specific geotechnical investigation and design measures would be required to ensure stable final slope configuration Wasatch Fault appears to cross 1450 E alignment 4 or 5 times. Faults not located with detail or accuracy. Trenching studies would be needed to identify fault locations (Golder, 2010). Golder Assoc evaluated the No Action/ Alt 3 in vicinity of 1450 E. Found pipeline construction on 1450 E presents least favorable alternative for pipeline integrity; potential geologic hazards (Golder, 2010). RB&G Engineering performed a geologic hazards analysis in May 2010. Hazard analysis supports Golder findings. Traffic Traffic considerations for Seven Peaks Blvd, 1450 E, 2200 N, 2320 N, and University Ave discussed in Alt 1. Descriptions would also apply to Alt 3 alignment. N Temple Dr (1450 E to1200 E) closed with local access. 1200 E to 900 E, would have 2 traffic lanes. Utilities Utility relocation and avoidance procedures along Seven Peaks Blvd and 1450 E are described in the ULS EIS. 1450 E and N Temple Dr have moderate utility congestion. 1450 E contains parallel 8- and 16-inch water lines which restrict the width of corridor for the pipeline. Utility congestion along 2200 N, 2320 N, Canyon Rd, and University Ave is discussed under Alt 1 Schools & Residence 2 schools (Rock Canyon Elementary and Centennial Middle) Residential homes located along 1450 E, N Temple, and 2200 N.
