Synthetic Turf Replacement Project at Tom Bates Regional Sports Complex 
(aka Gilman Fields in Berkeley, CA) 

Latest Update (May 17, 2017):  

The City of Berkeley has evaluated the replacement option concepts that were discussed during the community process. This evaluation has taken impact safety (G-Max Rating), human health & environmental risks, liability, durability and playability, and community feedback into consideration.  

The decision making process and City of Berkeley recommendation are documented in a memorandum from the Berkeley City Manager to the City Managers and Councilmember Representatives of the Five Member JPA Cities (Albany, Berkeley, El Cerrito, Emeryville, and Richmond), dated May 15, 2017 (see link below).  



At the upcoming JPA Meeting on Wednesday, May 24, 2017, a discussion will be held to determine next steps in order to keep the project schedule for completion by March 1, 2018.

Wednesday, May 24, 2017
5:30 p.m. to 6:30 p.m.
Cypress Room, 2180 Milvia Street, 1st Floor, Berkeley


The final community meeting on the turf replacement project was conducted on March 25, 2017.

The project team described the project decision making process, presented the selection criteria including impact safety (g-max), human risk assessment, durability, playability, costs, and design options consideration.  The project team also introduced the replacement option concepts at the meeting. These concepts were presented at the JPA Meeting on March 16, 2017 to provide the JPA Cities a preliminary look at the possible options. The replacement option concepts include:    

  1. Replacement In-Kind. Monofilament Turf, Crumb Rubber Infill, and no Shock Pad  
  2. In-Kind with Upgraded Carpet. Dual Blend (Monofilament and Silt Film) Turf, Crumb Rubber Infill, and no Shock Pad  
  3. Coated Crumb with Upgraded Carpet. Dual Blend Turf, Coated Crumb Rubber Infill, and no Shock Pad  
  4. Optimized. Dual Blend Turf, Cork Infill, and Shock Pad.  

The City of Berkeley project team is in the process of consolidating the public comments received, community feedback generated from these two community meetings, and the technical information developed by our consultants.  City of Berkeley will inform the JPA Cities of this consolidated data, and facilitate the decision making process for the JPA Cities to select the optimal option at the next JPA Meeting on Wednesday, May 24th, 2017.

On January 28, 2017, an informational community meeting was conducted to present to the public some of the commonly used infill materials. The City presented project goals, described the constraints that the project will need to overcome, gathered the attendees’ feedback, and identified the priorities that the attendees are most concerned with. 

The goal of the project is to replace the existing worn out artificial turf at the north and south soccer fields, mitigate subsurface drainage problems while meeting the key project constraints, addressing community concerns/priorities, and providing reasonable accommodation to the facility users yet delivering the project on time and on budget. 

The key project constraints include: safety of users, protection of the environment, durability, long term maintenance, initial and long term costs, and playability. 

Approximately eighteen member of the public attended this meeting. Their feedback were gathered by the project team, and the following community priorities were identified.  

  • A healthier, safer infill alternative to crumb rubber 
  • Assessment of life cycle costs 
  • Consider phased field development 
  • Cost is less of a priority than safety
