Background

The Delaware Addition Planned Development is a long-term, three-phase proposal to build housing, shops and industrial space on about 20 acres west of Swift Street in Santa Cruz. Phase II of the project is about 3.4 acres. 

The Santa Cruz City Council first approved planned development on the land in 2008.

Developer

The Santa Cruz-based Redtree Partners LP is the developer. RTP Delaware Avenue LLC is the development firm created for the project.

  • Affordable units: Seven low-income and 12 moderate-income units.
  • Height: Three four-story residential buildings, one two-story building with a leasing office and a fitness center and one single-story building with shops.
