Alternative Urban Areawide Review (AUAR) The site is not within the 2005 I-35E Corridor AUAR; therefore, no mitigation is required. Traffic Study A Traffic Study was prepared by Spack Solutions on December 6, 2019. The study was based on a concept plan with 74 single family homes. Based on ITE standards and local data collected by Spack Solutions, the development is forecasted to generate approximately 685 new trips per day with 50 new trips in the a.m. peak hours (7-8am) and 65 trips in the p.m. peak hours (4:30-5:30pm). Traffic impacts are analyzed in terms of volume and capacity. Volume quantifies how many vehicles are using the road and capacity quantifies the number of vehicles the road can accommodate.

Nadeau Acres will generate approximately 685 new trips per day. These new trips added to the existing daily trips are significantly less than the 2040 forecasted daily volumes. Traffic Capacity A ratio of volume to capacity is used to analyze traffic congestion. A road with a volume to capacity ratio of 1.0 means the traffic volume is nearly equal to the traffic capacity and will feel congested to motorists. Per the traffic study, three (3) sections of roadways (20th Ave north of Birch St, 201h Ave south of Birch St and Birch St) were analyzed under Existing, 2024 No -Build and 2024 Build scenarios. No volume to capacity ratio exceeded 0.45. None of study roadways are expected to exceed their daily capacities. 12
