North Natomas Regional Park: Bike Yard
Just how many bikes can you park comfortably in two automobile parking stalls? In the case of the newly installed Bike Corral at North Natomas Regional Park, about 24. Funding by the North Natomas Transmit Management Authority and the Sacramento Metropolitan Air Quality Management District allowed the conversion of two existing 9’x18’ parking stalls to increase bike parking at the 47-acre park (where Callander has also had a hand in designing a dog park and trail upgrades).

The new 10-rack “Bike Yard” plays off of existing color and materiality in the park. It is enclosed by pre-cast split rail fencing adorned with laser cut steel lettering. Diagonal concrete score joints demarcate potential future color banding to create horizontal interest. Several existing bike racks were relocated from other locations in the park into the corral to reduce cost and increase efficient use of a tight space.
With the added bike parking a new bike valet hub becomes available for numerous events that take place in the park whether it be a bike-in movie night or seasonal farmer’s market. Additionally, increasing the amount of available bike parking will hopefully aid in reducing car dependence that is prevalent in suburban neighborhoods and encourage more trips by bicycle leading to a more vibrant and healthy North Natomas!
The North Natomas TMA is now accepting grant applications for North Natomas businesses that want to install placemaking infrastructure that helps encourage pedestrian and bike traffic. More information can be found at the following link:

Field Trip : Connect and Sustain Action Groups
On a picturesque Tuesday in early May, members of the Live and Work, Recreate, and Connect Action Groups gathered together to learn about a brand new community development in San Mateo called Bay Meadows. Described as “a charming urban village…Bay Meadows combines the communal feeling of the suburbs with cultural aspects of the city.” With amenities ranging from urban gardening to bocce ball, to yoga in a park, we were eager to see for ourselves exactly what made Bay Meadows such a special development.
Briefly after gathering in Landing Green Park, our group got the chance to speak to a Bay Meadows representative about the current state of the development. She explained to us that Bay Meadows provides an array of single family homes that are either nestled within mixed-use development along Deleware Street (which is currently under construction) or overlooking one of Bay Meadow’s numerous parks. She also explained that she and others coordinate events like movies in Bay Meadows Park, Zumba classes, and social media giveaways.
We then took to touring the impressive development with a map in hand and a wide-eyed curiosity. Landing Green Park caught the eyes of our plant experts Pierre and Brenna in particular, and with good reason. The linear park’s plant palette skillfully mixed texture and color while still maintaining a drought tolerant status. Punctuated with a statement sculptural piece by Chuck Ginnever, it is easy to imagine a full day spent playing bocce ball, appreciating art, and taking a deep breath in the gardens of Landing Green Park, but alas we had plenty left to see.
Immediately after our Landing Green Park daydream we moseyed over to arguably the most remarkable piece of the Bay Meadows expanse, Persimmon Park. Flanked by cozy townhomes, Persimmon Park holds 99 gardening beds providing members of the community an opportunity to cultivate their green thumb. For those who are not quite as horticulturally savvy, there is a resident gardener who frequently provides insight and classes. Persimmon Park is more than just a space for gardening, though. An incredible 30’ community table and adjacent barbecues offer community members a unique dining opportunity; and with a nature play area anchoring Persimmon Park, it would not be a surprise if all children living in Bay Meadows quickly stopped being so finicky with their vegetables.
There is little doubt that Bay Meadows serves as an exciting precedent for comprehensive community developments throughout Northern California in the future. What makes Bay Meadows particularly interesting is the commitment to both thoughtful space and thoughtful programming. These principle’s serve as important reminders to the Callander team and to all Landscape Architects that our spaces serve as more than just beautiful backdrops, but also as an active space for people to live their lives.

Jess Jackson Sustainable Winery Facility Tour Part 1: Building Energy Efficiency
In late August 2015, the Callander Associates Sustainability Interest Group visited the Jess Jackson Sustainable Winery at UC Davis to learn more about the sustainable practices implemented there. The facility is self-sustainable in energy and water and “fully solar at peak load with a zero-carbon footprint,” making it a superb example of how these practices can be used in real-world situations. Dr. Roger Boulton, a winery-engineering expert and the Stephen Sinclair Scott Endowed Chair in Enology at UC Davis, walked the group through the overall processes and specific interventions for on-site energy production, energy efficiency in building design, capture and reuse of stormwater in the landscape, and carbon sequestration. His insight and expertise also illuminated several good practices in infrastructure design that contribute to project sustainability by reducing the amount of work that needs to be done and redone over the lifetime of the project.
The Jess Jackson Sustainable Winery Facility Tour can be broken down into three major categories of importance including building energy efficiency, water capture and reuse efficiency, and good practices in infrastructure design. This article will focus on the first category: energy efficiency in building design.
According to the UC Davis College of Agricultural and Environmental Sciences, the Jess Jackson Sustainable Winery is “expected to be the first building at any university to be certified [as] Net Zero Energy under the Living Building Challenge and [is] only the second such building in California.” It is a fully solar-powered facility, with solar panels on the roof of the winery and adjacent buildings producing twice as much energy as is consumed by the winery on a peak energy-use day. Future plans for new-generation solar panels and 2nd life lithium batteries will allow for improved efficiency and storage of surplus energy. Strategies to reduce overall energy use include:
- Solar tubes for lighting scatter light effectively on sunny days, reducing need for artificial lighting
- Heating and cooling of water is carefully managed and minimized
- Ice for cooling water is saved and topped off each day rather than making new ice every day
- Conservative engineering of water filtration system – water use for a winery peaks in fall but is minimal throughout the rest of the year, so water can be captured and filtered for storage from the beginning of the rainy season to the beginning of harvest. The pump size and energy demand are minimized by filtering water slowly over the whole year to meet fall’s peak demand.
Of particular interest are the innovative systems used for heating and cooling the winery, which drastically reduce energy demand. The building envelope is highly-insulated and is considered to be “tight,” having minimal leakage (additional technical information can be found here) and therefore maintaining cool temperatures even during Davis’s hot summers. The following passive cooling techniques are utilized to minimize energy use:
- Fans pull cool outside air into the bottom of the building at night, warm air flows out top windows (which open automatically)
- Cooling system turns on based on the change in the outside air temperature (when the nightly low temperature is reached) rather than based on time or on threshold temperature. This minimizes run time needed to achieve cooling.
- Vines and roof overhangs on east and west sides of the building shade the walls. Vines were chosen instead of trees so as not to shade the solar panels on the roof.
These strategies result in an approximately 4°F flux in internal building temperatures on a day with 40°F flux in outside temperatures! While many of the energy saving practices in the building design are impressive, stay tuned for Part 2 of the Sustainable Winery Facility Tour which will discuss water capture, reuse, and moreover water efficiency principles which can be applied to the landscape.
