San Jose Overfelt Gardens Master Plan - Community meeting and Survey

The City of San José is undertaking a master planning project to reinvigorate and revitalize the Overfelt Gardens. Overfelt Gardens is a lovely nature park in great need for TLC. Please consider responding to this short survey, and ask the city to invest in restoring and expanding the native plant gardens.

You may also participate in the Overfelt Gardens Park Master Plan Community Meeting #2 on Thursday, May 20 from 6:30 - 8:00 p.m. via Zoom.


San Jose Light Tower

Recently, San Jose City Council advanced the Urban Confluence project. The City, led by Council Member Davis, provided some direction to ensure that the project is not a financial burden to the City, ask that the design be done to the “highest environmental excellence standards” to avoid rather than mitigate negative environmental impacts, and call for citywide outreach.

San Jose residents, please email Deputy Director Nicolle Burnham at nicolle.burnham@sanjoseca.gov to ask for an impartial, citywide survey that provides arguments for and against the project to guarantee that our community is informed and engaged with the process.

Say No to Light Pollution in San Jose

What is happening:


The San Jose Light Tower Corporation (AKA Urban Confluence Silicon Valley) selected an illuminated structure made out of 500 20-story white rods to be “gifted” to San Jose and placed in Arena Green park in downtown. This 150 million dollar structure, intended to be an icon, will cast devastating amounts of light pollution city wide and draw birds to their death, at the confluence of the Guadalupe River and Los Gatos Creek. San Jose leaders crave the recognition that iconic structures can bring, but should our City become famous for environmental degradation and light pollution?


Why is this important:

Light pollution is no trivial matter. It disrupts biological functions in all living things, and harms ecosystems, wildlife and human health.

This 200 foot tall light generating structure will shine across the City, spill light into the confluence of waterways on the valley floor, and will be visible all the way to Mt. Hamilton and Mt. Umunhum. This light will keep residents up at night, disorient and harm birds and wildlife, and pollute our view of the night sky. It could interfere with the research function of the world-famous Lick Observatory. It can distract pilots as they land at the nearby airport.

What can you do?


Please call or write to Mayor Liccardo and San Jose City Council and tell them that you are a San Jose resident who is opposed to the light tower project (see contacts and links below).

  • The wrong structure - An imposing 200-ft tall, massive, illuminated structure will generate unacceptable, city wide, light pollution. This structure generates light pollution intentionally, by design, making it impossible to shield and protect residents, waterways, wildlife, and the dark sky from harm.

  • In the wrong place - Arena Green Park is the confluence of two important waterways, and two riparian corridors. It is also an important community gathering place. This Project would dominate our public space and harm our riparian ecosystems, birds, fish beavers, and wildlife by lighting up this sensitive environment.

  • At the wrong time - As the human and economic losses of the pandemic continue to haunt our community, San Jose should encourage investment in what people need and want - not in top-down projects.

  • The wrong symbol for San Jose - The illuminated white light rods of this structure are intended to represent Silicon Valley Tech companies. Our diverse community is not represented in this monolithic white structure that can harm us with light pollution. The promoters showed little interest in diversity, equity or inclusion.

  • Let’s help our community instead - The City should instead direct philanthropy to an environmentally sensitive project that improves our lives and represents San Jose’s culture and community.

Opinion: Why San Jose should reconsider Urban Confluence project

By SHANI KLEINHAUS and KATJA IRVIN

The Urban Confluence project proposes a $150-million modern resurrection of the San Jose light tower. While this might seem attractive to some, San Jose leaders should recognize the harm that a 200-foot illuminated structure will cause to the environment and to residents. Science tells us that light pollution generators should be perceived as any other source of contamination due to pervasive and devastating effects on health and nature. Regressive projects such as this should be a thing of the past.

Death sentence to birds (and aircraft). Light pollution is emerging as a novel global threat to ecosystems, with widespread biological harm similar in scope to climate change. Among the victims of over-lighting are birds. Their migratory behavior is altered by light. Birds’ attraction to light should not come as a surprise to San Jose. Historical records show that birds were drawn to the original light tower: “Birds and insects came in violent contact with the tower and the electric wires and fell to the ground below dead” and locals “made money selling birds that collided with the tower to local restaurants.” Why recreate this horrific scene? Furthermore, airports discourage Illuminated attractions because interactions between birds and aircraft can be fatal to both. Is it wise to attract flocks of nocturnal migratory birds to the edge of the Airport Safety Zone?

Dark creek corridors are essential for wildlife. At the confluence of the Guadalupe River and Los Gatos Creek, Arena Green Park is a remnant of times where creek side ecosystems thrived. Despite the stresses of urban life in contemporary days, these creeks still support threatened fish species, migratory birds and the occasional beaver. All depend on darkness in their lives. Increased ambient light here will interfere with animal movement and with wildlife’s daily and seasonal behavior. Why rob our wildlife of their habitat?

Residents value nature in parks. Pre-COVID-19 surveys show that San Jose residents prioritize access to the wild even in the city’s core. Residents want clean, maintained parklands and ecologically viable creek corridors. Monuments and tourist attractions ranked lowest on the list. Why not give San Jose residents a butterfly garden, a clean creek and shaded park? Acknowledge the public’s post-pandemic hopes and aspirations and ask what residents value most?

Art is in the eye of the beholder. One cannot ignore a 200-foot illuminated structure on the valley floor. San Jose leaders can expect many people to have a strong aversion to it. It will dominate San Jose’s night sky and, like electronic billboards viewed at a similar distance, the view from the hills will be a blob of light pollution. Similar to the Los Angeles “Reef” project, which is visible from a great distance day and night. Resident’s dismay and complaints are sure to follow. Why increase public anxiety and consternation?

The pandemic sharpened our senses and helped us appreciate the value of nature, of birdsong, of dark starry nights and the beauty of the Milky Way. Why would San Jose willfully select an icon that obscures the sky and symbolizes a legacy of dead birds and enduring environmental harm? An illuminated tower anywhere in the city will be harmful to our environment and should not be promoted in the 21st century. It is time for San Jose to reconsider this project, and, hopefully, direct philanthropy in the city to better causes.
