Happy Valley Road: Pima Road to Alma School Road

Ardurra delivers roadway design services for approximately 2 miles of arterial roadway widening, creating complete street corridor improvements enhancing mobility, safety, and community connectivity. The project provides two through lanes in each direction, with advanced intersection design, multimodal facilities, and integrated stormwater management systems that support Scottsdale's sustainable transportation vision.

Working closely with city staff, the team developed two alternative geometric configurations for a multi-lane roundabout, ensuring conformance with design intent while minimizing right-of-way encroachments. Strategic coordination with adjacent regional drainage improvement projects created cohesive drainage infrastructure networks, maximizing community benefits and operational efficiency.

Key Project Components:

• Designed a 2-mile arterial roadway widening providing two through lanes in each direction with complete street improvements

• Engineered two multi-lane roundabouts, developing alternative geometric configurations, minimizing right-of-way impacts while meeting design standards

• Integrated multimodal facilities, including bike lanes, sidewalks, and multi-use paths, enhancing pedestrian and cyclist connectivity

• Designed raised median infrastructure, improving traffic safety and providing opportunities for aesthetic enhancements and landscaping

• Coordinated comprehensive utility systems, ensuring seamless integration with existing infrastructure and future development needs

• Developed regional and roadway hydrology with off-site drainage conveyance systems supporting comprehensive stormwater management

• Collaborated with adjacent project teams, creating a cohesive drainage infrastructure network, maximizing regional benefits and efficiency

The corridor improvements demonstrate an innovative complete-street design while supporting Scottsdale's commitment to sustainable transportation infrastructure. Strategic roundabout design and multimodal integration provide enhanced mobility options while creating lasting community assets that support economic development and improve quality of life.
