Novato Council to Review Hill Road Recreation Plan

The suggested first phase of work includes four pickleball courts, expanded parking with a lot along Hill Road and a synthetic turf field with spectator seating. All components would be accessible to the disabled.

The plan also calls for a half-mile lighted path.

Additional project phases would include the installation of bocce courts, playground equipment, a second synthetic turf field and more parking.

All fields would be multi-use and open for soccer, lacrosse, baseball and other recreational activities, said Vincent Lattanzio, principal and president of Carducci and Associates, of San Francisco.

With added synthetic turf, the proposal would reduce maintenance costs, officials said. It would also allow for recreational use of fields during winter months, when the city’s natural fields are typically closed to the public, [Novato Park and Recreation Director Pam] Shinault said.

“With synthetic turf, you expand use for three additional months in the winter,” she said. “You can use them when they’re raining. We close natural turf area for three months in the winter. We do that so the fields are not damaged in rain and the grass has a chance to rejuvenate.”

Contested Turf in San Francisco Bay Area Sports Field Design / Designing for Synthetic Turf Fields

Sports fields provide a surprisingly complex terrain for landscape architects. Multi-use athletic fields ground significant contemporary themes in landscape architecture’s professional and academic worlds: the duality of the natural and the artificial, ecology as the protagonist of a design, and the unsung role of maintenance. Conversations during their site design process can play into a cultural aversion to material artifice or into the aesthetic preference for an evergreen lawn inherited from England.

Benefits to Synthetic Turf Field Applications

The following land use, ecological, and athletic issues contribute to the growing use of synthetic turf:

- conflicting demands of natural turf for maintenance (which, like other biotic things, needs to breathe) and of a large population for play space in the expensive San Francisco Bay Area,
- shrinking maintenance budgets,
- creating a literal ‘even playing field,’ by avoiding soil’s lumpiness and grading for drainage, and
- growing public demand for low-water, drought-resilient landscapes.

Evolving Scientific Research and Site Design

But a synthetic turf sports field also raises emotionally-charged concern over its impact on the environment and on health and safety of athletes, especially children.

On public projects, landscape architects are caught in between those convinced synthetic turf is harmful and those convinced synthetic turf is safe, each citing different studies. Anticipating this challenge, Carducci Associates mediates between the diverse priorities of public field users, scientific findings, and clients. Bringing scientists, with expertise in the material components of synthetic turf and in research processes, into design and public processes helps.

Within the nuanced process of designing a synthetic turf field, infill has become one of the most controversial components. A granular material that works as a synthetic stand-in for soil, infill is often comprised of crumbled, recycled rubber tires. Crumb rubber has raised concerns nationally and locally, from a recent artificial turf installation at the Beach Chalet Fields in San Francisco’s Golden Gate Park, to a multi-agency federal initiative launched in February 2016 known as the Federal Research Action Plan on Recycled Tire Crumb Use on Playing Fields and Playgrounds. In June 2015, the California Environmental Protection Agency the Office of Environmental Health Hazard Assessment (OEHHA) committed under a contract with CalRecycle to conduct a new study on synthetic turf and potential human health impacts.

While crumb rubber is under scrutiny, user groups are calling for infill alternatives that contain materials like recycled athletic shoes, cork and coconut, or other synthetic materials. The Los Angeles Unified School District and the New York City Department of Parks and Recreation no longer use crumb rubber. In the greater San Francisco Bay Area, dozens of facilities (including schools, public parks, the Facebook Corporate Campus) have used infill alternatives fabricated with cork, organic fiber, recycled turf, sand and TPE (a plastic).

Carducci Associates’ Leadership in Sports Field Design

For community meetings, Carducci Associates has analyzed more than a dozen synthetic turf infill materials with its team of experts: Principals Bill Fee and Vince Lattanzio, Associate Principal Wesley Bexton, Senior Associate Alvin Tang, and Associate Philip Dinh (bios here). While comparing playability, cost, material components, and maintenance, alongside a timeline of political, funding, and construction processes, we record and respond to public questions and concerns. Attendees’ priorities at recent community meetings focus on long-term ecological, economic and health concerns:

1. Install a non-crumb rubber field that allows for healthy recreation.

2. Study the lifecycle costs of crumb rubber and alternatives, beyond capital cost, to address disposal and longevity.

3. Consider phasing strategies that permit for more expensive alternative infills.

4. Cost is less of a priority than health and safety.

The results of current federal and state studies on crumb rubber infill have yet to surface in part because the health impacts of exposure will be studied during the hottest months of 2017. While agencies, designers and athletes wait for the outcome, landscape architects should study and incorporate the research findings that are available on crumb rubber and alternative infills, and engage in outreach and discussion with athletes, coaches and families on their preferences for and experiences with synthetic turf fields and different infill.
