Landmarks are not frozen in time. They are not like prehistoric insects preserved in fossilized amber. They are living and their heritage is nurtured by community commitment and individual involvement.
In 2014 Observatory Park was dedicated to the people of Ukiah. From that day forward a commitment was made to preserve the Ukiah Latitude Observatory and for the park to become part of Ukiah’s living heritage.
Be a part of the heritage and come enjoy this unique park located at the 400 block of Observatory and Luce Avenues.
The International Latitude Observatories were a system of (originally) six observatories located near the parallel of 39° 08′ north latitude. They were used to measure the variation in latitude that occurs as a result of the “wobble” of the Earth on its polar axis.
United States Coast and Geodetic Survey joined the International Polar Motion Service program in 1897 to study the precession, or “wobble” of the Earth’s axis, and its effect on measures of latitude. Six separate observatories were created along the parallel 39° 08′ north latitude. The alignment of all six stations along the parallel helped the observatories to perform uniform data analysis.
Economic difficulties and war caused the closings of some of the original stations, though a newer station was created in Uzbekistan after World War I. The various stations continued to function until advances in computer technology and satellite observations rendered them obsolete in 1982. The data collected by the observatories over the years still has use to scientists, and has been applied to studies of polar motion, the physical properties of the Earth, climatology and satellite tracking and navigation.
The small size of the building (12 feet square) and the esoteric character of the work that took place within speak modestly of the international importance of the landmark. The research provided all data used in polar motion studies for decades, and fostered international cooperation which transcended the differences between man during times of war and international strain.
The city acquired the property in 1991 but the observatory and adjoining land was closed to the public until March 2014. A $54,000 grant from the California Land and Water Conservation Fund, along with matching funds from the City of Ukiah, made the improvements necessary to reopen the park.
A large heritage Valley Oak anchors the north end of the park. Spreading before it is a large grassy field providing an unobstructed view of the iconic tree.
Ukiah’s first Pétanque court was completed in 2010 for the game of boules, or balls, closely related to bocce by the Redwood Empire Boules Club.
A peace pole, dedicated to Erica Enzer, an international peace activist and former member of the Ukiah War Resistor’s League is located adjacent to the Grove of Nations (trees representing each of the regions where the latitude observatories were located).
The park has had improvements made before its public opening, including the restoration of the historic observatory and a labyrinth (pictured at left) installed in 2005.
The former observer’s residence has been used by Ukiah Unified School District since 2011 for the Community Transition Program which assists special needs students aged 18 to 22.

Observatory Park is the home of the Ukiah Latitude Observatory, one of five international latitude observatories around the world operated from 1899 to 1982. The City of Ukiah offers several events associated with this unique park:
There is no charge for these events. Reservations are required and young children are welcome with a supervising adult. If you have questions, are interested in upcoming lectures, would like to schedule a tour, or are interested in finding out about the public viewing nights, call (707) 463-6231
The Planet Walk at Observatory Park is a scale model of the solar system designed to fit within the boundaries of the walking path inside the park. Most people know that the planets orbit the Sun, but it is difficult to visualize just how small the planets are compared to the immensity of the Sun. It is equally difficult to imagine the vast empty spaces between the planets.
The Planet Walk is designed to give you a first-hand experience of the distance between the planets in a walkable scale. To accomplish this, the solar system is shrunk down so that the Sun is roughly the size of a lemon. This will make the Planet Walk small enough to include all eight planets and Pluto, because even though Pluto has been reclassified as a “dwarf planet”, we did not want to leave it out.
To begin the Planet Walk, you will start at the sign representing the Sun on the north end (Luce Avenue side) of the walking path at Observatory Park. Follow the path counterclockwise to find markers representing each of the solar system’s planets. Each planet marker tells you approximately how many miles apart the planets are and the distance to scale.
The benefit of this project is a new community educational resource. The Planet Walk can be used for school field trips, giving a lot of kids a chance to walk past the planet markers and learn about the solar system, and it will also be a fun activity for any park user that is interested in the solar system.
To make your own walkable solar system use this free calculator from the Exploratorium. https://www.exploratorium.edu/explore/solar-system/activity/build-model

Water-Efficiency, Treatment, and Storm Water Improvements
Wastewater Treatment Plant
The City of Ukiah has made significant investments to build conservation into the structure of our operations. A critical component of our structural conservation has been our state-of-the-art wastewater treatment plant. This plant has allowed us to reduce overall water use, reduce discharges to the river, and enhance the supply of sustainable, reliable water resources. The treatment plant also relies on LED lighting and Variable Frequency Drive (VFD) motors, which greatly increase energy efficiency.
Ukiah secured a grant from the State Water Resources Control Board to cover about a third of the cost of the recycled water system and secured another grant from CalRecycle to filter storm water before it is discharged to the river.
Learn more about the wastewater treatment plant.
Converting Water Fixtures
As the City modernizes its buildings, we are replacing traditional toilets and sink faucets with low flow fixtures, significantly reducing the amount of water used in our facilities.
Using Recycled Water for Outdoor Irrigation
The City is using recycled water at the Ukiah Sports Complex, at Oak Manor Elementary, and Oak Manor Park, keeping our fields and parks green while also promoting responsible and sustainable use of our water resources; additional expansion of the recycled water program is underway. Learn more about the Recycled Water Project.
Reducing Vehicle Miles Traveled
Bike Lanes
There are currently approximately 11.2 miles of class II bike lanes in the City of Ukiah. The City is in the design process and intends to expand the distance of bike lanes to 3.8 miles, which will be a total of approximately 15 miles.
Expanding the Great Redwood Trail – Ukiah
With broad public support, the City has been very active in developing the Great Redwood Trail within the City limits. The existing 2 miles of class I multi-purpose pathways provides a safe and efficient corridor for bicycle and pedestrian traffic to access major employment centers, services, shopping, residential areas, and the future Mendocino County Courthouse, as well as connectivity to other bicycle routes throughout the City. The fourth phase of this trail will add an additional mile and complete the trail within the City limits from north to south. Learn more about the trail.
Our Electric Utility
Learn more about the Electric Utility as well as few simple things you can do at your home and at work to reduce your own energy costs.
Parks and Recreation
The City secured an Urban Greening Grant from the California Natural Resources Agency, which is part of California Climate Investments, a statewide initiative that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment. This $1.78 million grant was awarded in 2017 and used to support the build-out of the Rail Trail.
At the direction of the City Council, the City of Ukiah Paths, Open Space and Creeks Commission prepared a document establishing the policies and procedures for the City crews and other agencies and organizations to follow when performing creek maintenance and garbage and rubbish removal. Learn more.
In partnership with the Community Foundation of Mendocino County and the ReLeaf program, the Parks team has set a goal of planting 50 trees per year. An emphasis on planting trees that provide street shade will expand the benefit of the City’s urban forest.
Environmentally Friendly Land Use Policies
The City is in the process of updating its General Plan. Included in the proposed 2040 General Plan are new policies prioritizing complete streets, the development and implementation of a Climate Action Plan, preservation of agricultural lands and open space, and other climate friendly policies and goals. Additionally, Ukiah has created a Green Building Toolkit to actively promote energy efficiency upgrades for homeowners and contractors.
Increasing Recycling and Reducing Organic Waste
Transition to Cloud Computing
Our Hybrid Fleet and Clean Equipment
Well ahead of state goals, the City of Ukiah is replacing gas and diesel-powered vehicles and equipment with hybrid vehicles and Tier 4, California Air Resources Board compliant equipment. Ukiah Police have deployed an electric vehicle and all City vehicles that travel out of town are certified hybrid vehicles.
Ukiah has always been forward-looking with regard to electric vehicles. We have had electric vehicle (EV) charging stations since the 1980’s. Currently, the City has public EV charging at the public parking lot on Oak and Standley Streets.
The City has also invested heavily in retiring outdated diesel equipment and replace generators, mowers, and tractors and other equipment used by public works and parks maintenance teams with vehicles that are compliant with new emission requirements from the California Air Resources Control Board.
Lighting Upgrades at City Facilities
City facilities have transitioned to energy efficient LED lighting, which are estimated to consume 75% less energy and last 25 times longer than traditional incandescent lighting. These changes resulted in significant cost savings for the city.
The facilities that have made this conversion include the Ukiah Valley Conference Center, the Grace Hudson Museum, City Hall, the Water Treatment Facility, and more.
Storm Drains and Your Home
Protecting Our Emissions Savings by Preventing Fires
We have also streamlined how our fire response teams are structured to ensure full funding, adequate resources, and available equipment.
Ukiah Valley Fire District Annexation
In November 2021, the Ukiah Valley Fire Protection District increased its service territory to include the City of Ukiah within its boundaries, creating a unified district that serves the entire Ukiah Valley. This annexation of service territory resolved a funding discrepancy, establishing an additional $900,000 to $1 million in annual revenue necessary to meet the growing needs of our region. This has included:
Converting to Solar Energy
To reduce our reliance on the electrical grid, the City of Ukiah has identified city buildings ideal for solar installation. To date, the City has installed 40 Photovoltaic (Solar) panels at the Civic Center, saving the City approximately $26,061 and reducing our carbon footprint by 42.6 metric ton over 17 years.
Additionally, the water re-circulation system that heats the Ukiah Municipal Swimming Pool is 100% solar powered.
The City continues to pursue funding opportunities to outfit additional municipal facilities with solar. The City is currently involved with adding 123 kW of solar system at Anton Stadium parking lot. This solar system will help reduce our carbon footprint by approximately 62 metric ton yearly. We have also implemented automation for heating and cooling of City facilities to reduce power use during peak times.
