TRAFFIC & PARKING IMPACT LETTER - DRAFT ANOKA RAMSEY ATHLETI C ASSOCIATION DOME INTERSECTION ANALYSIS AND RECOMMENDATIONS According to the completed traffic modeling, the new traffic generated as a result of the proposed facility will increase vehicle traffic volumes to varying degrees at the studied intersections: INTERSECTION 1 • Will operate at a LOS B for all No Build and Build scenarios. • The proposed traffic will increase the intersection delay in 2024 Opening by 1.5 seconds compared to the No Build scenario without modifying the signal timing. Cycle length is estimated to be 70 seconds. • The intersection signal timing was optimized for the 2027 Full Build and 2034 Future scenarios from the No Build scenarios. This resulted in a reduction of the intersection delay of 3.1-3.6 seconds from the No Build scenarios. A 70-second cycle length. • It is recommended to evaluate the existing access within the eastbound left -turn -lane taper of Intersection 1 to reduce conflict and delay. The potential improvements to Ferret Street Northwest are recommended to explore circulation improvements within The COR. • Intersection utilization is not changed from No Build to Build scenarios. INTERSECTION 2 • Will operate at a LOS A for all No Build and Build scenarios. • Currently the intersection is not signed with all approaches moving freely. With the low traffic volumes, the intersection is anticipated to minorly be impacted as traffic continues to grow. Per MUTCD, unsignalized intersections in a signalized area should not be uncontrolled. It is recommended that with future improvements, the westbound approach equipped with a stop sign. All build scenarios are modeled with this modification. Note that if improvements are made to Ferret Street Northwest, the operations of this intersection will be impacted. • Delay increases for the overall intersection by 4.7 to 5.1 seconds compared to the No Build scenarios. • Intersection utilization is not changed from No Build to Build scenarios.
