Rengstorff Avenue Green Complete Street

A Council-directed project connecting safer transportation, green infrastructure, and a long-running CIP commitment.

Rengstorff Green Complete Streets entered Mountain View's five-year CIP through Council consensus in 2023. The adopted project combines protected bikeways and safety improvements with green stormwater infrastructure, street trees, and native pollinator landscaping.

A Caltrans SB-1 grant-funded study now evaluates the corridor, with preliminary design retained and increased to $2 million in the FY 2025-26 CIP.

Adopted / programmed

What Council programmed

The adopted Green Complete Street scope combines transportation safety and green infrastructure.

  • Class IV protected bikeways

    A bikeway that is physically separated from motor-vehicle traffic, rather than marked with paint alone. Separation can be provided by features such as curbs, posts, on-street parking, or a landscaped buffer.

  • Lane narrowing

    Reducing the width of vehicle travel lanes, typically to help manage traffic speeds and free up street width for bikeways, wider sidewalks, or landscaping.

  • Intersection improvements
  • Crossing improvements
  • Green stormwater infrastructure

    Landscape-based features, such as bioswales and planted medians, that capture and filter stormwater runoff rather than routing it directly into the storm-drain system.

  • Street trees
  • Native pollinator landscaping

    Plantings of locally native plant species selected to support bees, butterflies, and other pollinators.

What the grant is funding

The study is intended to enhance safety, incorporate green street elements, and improve multimodal access for people walking, bicycling, using public transit, and driving along the 1.7-mile Rengstorff corridor from El Camino Real to Leghorn Street.

Why Rengstorff qualified

  • Mountain View's High Injury Network
  • MTC's regional High Injury Network
  • AccessMV's identification of Rengstorff as the City's highest-priority corridor
  • Equity, mobility, walkability/bikeability, safety, sustainability, and consistency criteria
