These are five vacant lots totaling 3.92 acres, with an equipment rental lot sandwiched in between. This is prime Petaluma real estate that has been vacant for over 30 years.

This site is extremely well situated and is deemed a catalyst site whose redevelopment could revitalize the entire area. This property borders the bus Transit Mall on Copeland Street and the SMART train station at Copeland Landing. The Haystack properties are also bordered by several small retail and commercial businesses on Weller Street, which back up to the river, as well as a small City parklet (Cavanaugh Landing) which leads to the Turning Basin heading to downtown. The property is also across the street from the Petaluma River Park.

Haystack was formerly a railyard and is now considered a brownfield requiring some environmental remediation before it is developed. The land is owned by Pacifica Development, which proposed a four-story 182-unit housing project that also incorporated ground-floor commercial use, tenant amenities, parking, and private and public open spaces. The project received Planning Department entitlement in 2019 but has since been stalled due to financial infeasibility.
