1. City of Redlands Redlands Boulevard/Alabama Street/ Colton Avenue Revision to Intersection Improvement Plans January 17, 2012

2. What ’ s the Problem? N-S lanes are offset by 22 feet through the Alabama St./ Redlands Blvd. intersection. Traffic demands exceed the capacity of the intersection during peak hours. Unorthodox merge/intersection of Colton Ave. / Redlands Blvd.

3. Traffic Pattern Terminology “LOS” – Level of Service (Capacity vs. Demand) Ranges from A to F LOS “A” – Free Flowing Traffic LOS “C” – Occasional Traffic Restrictions LOS “F” – Jammed Traffic Condition

4. Solutions Improve the intersection geometry of Redlands Boulevard/Alabama Street (removes 22-foot offset). Improves vehicle traffic flow through intersections from a LOS “F” to LOS “C”. Create a signalized T-intersection for Colton Avenue/Redlands Boulevard.

5. Solutions (cont.) Incorporate value engineering to reduce property acquisition and construction costs. Proposed improvements be constructed as single phase, instead of multiple phases.

10. Comparison - overhead view Value Engineered Design

11. By reducing a single South-bound lane a significant portion new ROW from the northeast corner will no longer be necessary. LOS will remain at “C” for peak hours until year 2025 rather than 2027. Value Engineering

12. Property Acquisition Reduction Implementing Value Engineering

13. Colton Ave./ Redlands Blvd. And Alabama St./ Redlands Blvd. Intersections Ultimate Design* Value Engineering Design** Cost Savings To t al $ 9,911,233$ 8,659,447$1,251,786 Estimated Cost and Time Savings 3 years reduction in time until construction *5 lanes for all approaches at Alabama/ Redlands Blvd. **4 lanes for south-bound approach at Alabama/ Redlands Blvd.

14. Authorize staff to proceed forward with the Value Engineered Design for the Redlands / Alabama / Colton intersection improvement project (LOS “C” - 2025). Authorize engineering service amendment with Parsons Brinckerhoff to prepare revised plans and specifications to implement the Proposed Value Engineered Design. Recommendation
