Environmental Activities FAQ

 

This fact sheet has been prepared by 1919 Crew, LLC (1919 Crew) to provide an update on environmental work at 1919 Market Street, Oakland, California (site).  1919 Crew has a voluntary cleanup agreement with the Alameda County Department of Environmental Health (ACDEH) to investigate and cleanup contamination found from historic site operations, prior to redeveloping the site into residential housing.  All environmental work is approved and overseen by ACDEH.   

 

Who owns the site and what is currently there?

1919 Crew is the property owner.  The site is vacant and fenced and consists of a partially demolished warehouse that was previously used as a live/work space.

 

What is the planned development for the site?

1919 plans to redevelop the site into 63-units of residential housing with common spaces.  The outer walls of the former warehouse that remain will be incorporated into the new development.  Property redevelopment will not begin until the ACDEH determines environmental issues at the site have been resolved and the site is cleaned up to allow for residential redevelopment.

 

What were the former operations at the site and associated environmental issues?

The site was used as a Greyhound bus fueling station, repair facility and auto paint shop from 1951 to 1960.  Since 1960, the site was used as a warehouse for various commercial uses including plumbing and mechanical contracting. In 2001, the site was converted into live-work units and tenants resided on-site until early 2016.

 

In the 1990s, two former underground storage tanks that held petroleum were removed under County oversight. In 1999, the County issued a no further action letter for this work closing the case; however, the letter stated further environmental work may be needed should the site be redeveloped.

 

In 2016, with County oversight, the 1919 Crew conducted environmental investigations which found volatile organic compounds (VOCs) in soil and soil vapor (air in between soil particles).  The VOC’s are likely from solvents that were used during past bus repair and fueling operations.  Under some circumstances, VOC’s can move through soil and cracks in a buildings foundation, potentially impacting the quality of indoor air. This process is called vapor intrusion.

 

What are the next steps?

There are several steps that remain in the environmental process:  

  • Additional samples in on- and off-site areas will be collected to clearly define the extent of contamination

  • A soil vapor extraction (SVE) pilot test will be conducted to determine the effectiveness of this cleanup technology to remove VOCs from soil

  • A mitigation system will be designed for the warehouse that includes sealing the future building slab with a vapor barrier and installing an active venting system below the slab to prevent soil gas from entering the building

 

What is the project schedule?

We will submit workplans for the additional work to the County in DATE and anticipate conducting soil sampling field work and the SVE test in DATE.

 

When will construction of the residential housing start?

Construction of the new building will not begin until the ACDEH determines environmental issues at the site have been addressed in a manner that supports residential redevelopment.

 

Did the former warehouse contain asbestos?

Yes.  A through assessment of the warehouse was conducted to identify all asbestos containing material.  All asbestos containing material was abated and disposed of in accordance with California regulations and a report documenting this was submitted to OSHA. This work was done prior to warehouse demolition work.

 

Will you continue to communicate with us?

Yes.  We will issue work notices in advance of any field work and have set up a website that provides up-to-date information.
