But while I have written a bunch about parks and transportational access, I didn't think to include that as another topic in the series. The challenge is to ensure that as many parks as possible are accessible by transit. This, and other forms of accessibility, should be covered in a parks master plan.
Many of the signature parks operated by the National Park Service will sustain serious damage from climate change and managers will have to make hard choices about what elements of parks can survive and what will have to be abandoned ("Resist, accept, direct framework").

According to the Trust for Public Land (The Power of Parks to Address Climate Change, webpage, report) parks are good at greening.
- Eighty-five percent of cities are adapting parks and recreation facilities to address climate change
- Eighty percent are enlisting parks to counter urban heat
- Seventy-six percent are improving surfaces to reduce flooding and runoff from rains
- Twenty percent are actively managing parks and woodlands to sequester carbon dioxide, the main greenhouse gas responsible for climate change.
- Other cities are managing parks to reduce the risk of wildfire, restoring shorelines to absorb storm surges, and opting for renewable sources of energy.
- Cooling green space is not equitably distributed, however. Trust for Public Land analyzed the 100 most populous cities and found that the neighborhoods where most residents identify as people of color had access to an average of 43 percent less park acreage than predominantly white neighborhoods.
If 85% of cities are addressing parks and climate change, then my thesis that this is a gap in parks master planning practice is wrong. OTOH, it's a micro versus macro scale issue. And the reality is that the day to day operations requirements and the increased demand from the public for both more parks and more activities and facilities makes dealing with long term issues, like climate change, difficult.
- During heat waves now and in the future urban microclimates put human health at risk.
- Intercepting solar radiation is the most effective way to reduce the heat load on people.
- Reducing air temperature is the second most effective way to reduce heat loads
- Evidence-based climate-responsive design can make parks more thermally comfortable.
Elements of a Cultural Landscape Report, from the NPS brochure on Cultural Landscapes
Planning at the landscape scale for Sugar House Park: the cultural landscape. A way to tie the various planning approaches together is to use the cultural landscape planning framework, which looks at sites in a variety of ways.
For the purposes of Sugar House Park we should focus on the elements of land, vegetation, buildings, and history.

Parley's Creek and its watershed. In the 1800s, Salt Lake City got control of most of the water rights on nearby federal lands--the canyons--which are mostly controlled by the US Forest Service.
Water rights are controlled by Salt Lake City Public Utilities, which defines watersheds in terms of the production of culinary water, not the flow to the Great Salt Lake.
Parley's Creek and a pond are part of the Park, and part of the Jordan River watershed, which flows into the Great Salt Lake.
To SLCPU, the "watershed" ends at the mouth of the canyon and its water treatment plant. The Creek's contribution beyond the Canyon to "the general watershed" comes from water discharges into the Creek, but past the Canyon, much of the Creek derives from storm water. And these days we don't get a lot of rain.
Within the park the Creek is mostly daylighted, with a small section not, because it was contaminated when the site was a prison. The Creek Management Plan provides a number of recommendations for the Creek within the Park. But not much has been addressed since the plan was released in 2010!
As we gear up to do a new round of master planning, one element will be the Creek and pond.
The Park is implementing a wayfinding and interpretation signage system, so we have an opportunity to do some watershed interpretation.
On our list of things to do, we are organizing a kind of symposium of the area river and creek stakeholders so that we start moving on Creek issues. The state has the
Jordan River Commission, and the advocacy group, the
Seven Canyons Trust, works on creek daylighting issues throughout the County.
There are good models for better practice. Nearby Fairmont Park, run by the city, has done a lot with their portion of the Creek. Fairmont has springs, which feed
a fishing pond. Fitts Park in the City of South Salt Lake, which includes Mill Creek, has done nice stabilization work around their creek too.
Flooding/Flood control. In the 1980s, Salt Lake City experienced major flooding because higher than normal temperatures led to premature snow melt.
(Trent Nelson | The Salt Lake Tribune) High water levels in Salt Lake City's Sugar House Park on Wednesday, April 26, 2023.
As a result, Sugar House Park was rebuilt in part as a flood control structure. When snowmelt is high, Public Utilities will do water discharges so that the reservoirs don't overflow.
Water conservation. The park is a lot of grass and trees and we water it. I need to find out about the ability to use recycled water. I don't think Salt Lake City is set up for it.
Parks serve many people, therefore should remain a priority for water use, compared to other institutional users. But we need to be efficient. We are planning to add various monitoring sensors and upgrade the irrigation system ($1 million minimum) and other equipment to address this.
We need to collect and present information on water conservation and irrigation in our plans, on the website, etc.
Turf and plants. Grass uses a lot of water. Two years ago, Salt Lake City Public Utilities introduced
a turf blend that uses 30% less water ("
SLC's drought tolerant turf is such a hit, other communities in Utah want some," Utah NPR).
That's something to look at, but then we have a lot of grass we'd need to dig up. One option could be to convert some sections of the park to meadow.

Trees/arboretum. Trees: serve as shade devices, are an equity issue, and provide environmental benefits ("‘Turn Off the Sunshine’: Why Shade Is a Mark of Privilege in Los Angeles" and "How Decades of Racist Housing Policy Left Neighborhoods Sweltering," New York Times)
Planting new trees is important but faces challenges because of heat and water (Landscaping for shade, US DOE, "How Much Can Forests Fight Climate Change? A Sensor in Space Has Answers.," New York Times, "What About the Trees? Trees as Nature-Based “Shade Sails”," American Journal of Public Health, Your tree planting companion, TEAGSAC Urban Forestry Department, Ireland, "Cities Are Good at Planting Trees. They’re Not So Good at Keeping Them," Walrus).
Tree planting as a city equity measure is an important priority of the Salt Lake Mayor.

Over the next year
we are looking to become accredited as an arboretum, which provides another opportunity for environmental interpretation, improve tree cover, do fundraising, etc.

Creating an arboretum within the park is an opportunity to develop some great guides, brochures, education programs, etc. for interpretation.
Unfortunately, as more organizations shift to digital presentation, there is no longer access to the often great materials produced in the past. The quality of today's brochures pale by comparison.
Plus, most state and local sites don't do a very good job of putting their documents online to begin with
One of my ideas is to develop an online database of such historical documents. The closest we have is the database of the National Park Service's online brochures for the parks, as well as other materials. NPS archives don't have everything, but remain an incredible resource.
Fauna/biodiversity. Participating in the Bridge Park initiative 10 years ago ("Revisiting the 11th Street Bridge Park project as an opportunity rather than a folly: a new revitalization agenda for East of the River, DC"), I was struck by how one of the design teams focused on providing food not just for people, but for flora and fauna in and along the Anacostia River.
Mowing grass too short can cut the tops off flowering plants, creating lawns that are inhospitable for pollinators seeking habitats in which to feed, rest and nest, experts say. Keeping your lawn neat and trim not only is resource-intensive but can also affect its overall health.

... creating a
pollinator lawn will take a bit more thought than just letting grass grow freely, experts say.
“If you have a traditional lawn, letting the grass grow to a foot tall or whatever it would be at the end of May is no value whatsoever,” says Susan Carpenter, native plant garden curator at the University of Wisconsin-Madison Arboretum. Grass that long could be harmful to lawn health and become a mowing nightmare.
To expand fauna diversity, perhaps we should install bat houses and beehives. We do have a community garden, and are looking to create another.
Of the entire park, only a small section along the Creek is "more wild."
Mows to Meadow Project in Philadelphia's Fairmount Park is converting some grass areas to meadows planted with native plants.
We may wish to stop mowing some parts of the park to increase opportunities for fauna ("
Meadow Developing in Flagstaff Park to Restore Habitat," Cambridge, Massachusetts).
The south side of the park abuts the I-80 freeway so it's very noisy.
Long term, we could deal with UDOT to increase plantings on the abutting embankment to support fauna (Roadside Best Management Practices that Benefit Pollinators, FHWA) and reduce noise (that section of freeway used to be part of the park).
How much do we manage the park for people and for fauna is a question definitely not posed by the existing master plan.
Ducks and dogs as disease vectors. Sadly, because of the pond, the park has a hell of a lot of ducks.
Which end up contributing e. coli to the Jordan River watershed, which in turn flows into the Great Salt Lake.
Who knew e. coli could be a park management issue.
Errant dog owners who don't clean up after their pets are big contributors too.
Plus people feed inappropriate food like bread to the ducks. We have signs up, but it doesn't matter.
Transportation demand management. Despite all the media coverage about how environmentally-conscious Utah is, the fact is that the predominate land use and transportation planning paradigm is sprawl. While there is a transit system that is decent for what it is, but most everyone drives.
Motor vehicles significantly contribute to the air quality problem. A lot of patrons come to the park by car. Can we reduce our park's contribution to the problem by working to improve biking and transit options for getting to the park?
Klyde Warren Park over Woodall Rodgers Freeway, Dallas (History).Noise/Freeway decking/capping. To deal with aesthetics, noise, and opportunity, I have a crazy idea to deck/cap the freeway section like Klyde Warren Park in Dallas or the Big Dig in Boston.
Many cities are pursuing such projects ("Philly’s other big I-95 project to start: A cap with an 11.5-acre waterfront park, South St. pedestrian bridge," Philadelphia Inquirer, "Feds grant $450 million toward I-5 freeway caps in North Portland’s Albina district," Portland Oregonian," "Interstate 5 in Downtown Seattle: Put a Lid on It?," Seattle Met).
Because the section next to the park (it was part of the park before the freeway was built) is so big--40 acres--it presents better opportunities compared to most other cities. It would cost hundreds of millions and take at least a decade to plan and build.
Climate change effects on park visitors
Hubert H. Humphrey Memorial Park, Pacoima, California. Thermal radar shows the differences in heat on a basketball court after reflective paint coatings were applied.
Sun and heat. Parks need to acknowledge heat and climate as issues that can suppress park use. For example, brutal heat in July and August means kids probably stay inside.
We have an open basketball court at Sugar House Park, and last summer I went up to some teens and asked them questions about what they thought about the amenities.
They mentioned shade was an issue commenting how they liked the trees that were there. I came back with suggestions like an additional (perhaps temporary) small shade structure, misters, and adding more trees as shade devices--we can take out a bit of asphalt and add trees. They also mentioned their desire for a water bottle filler at the nearby restrooms.
Shade screens and misters. A park in South Salt Lake, Fitts Park, has a shade screen over their playground, and it makes a significant different in heat between shade and sun. Surprisingly, shade screens are few and far between.
Phoenix and some other cities have developed community shade plans with parks and open spaces being key to responding to the challenges presented.

Playground equipment gets super hot in the sun. The Washington Post had a great article, "Kids getting burned on swings and slides? Here’s how to fix it," about research on heat and playgrounds.
-- Guide to Climate Friendly Playgrounds, Western Sydney University
-- "Outdoor playgrounds and climate change: Importance of surface materials and shade to extend play time and prevent burn injuries," Building and Environment (2022)
Shade screens can make a 20° or more difference between shade and direct sunlight.
Hydration. An issue. Should we have more water stations? It turns out over 80% of the park's budget is spent on utilities including "culinary water."

Climate change as an opportunity for civic engagement within parks and parks systemsSustainability education. Dealing with climate change as it effects a local park is the opportunity for teaching and learning about the environment.
Repositioning environmental issues around sustainability leads to renewed interest and innovative approaches to issues.
When I worked in Baltimore County in 2009/2010, I was struck by the rise in interest and involvement in sustainability. At the time many communities were creating sustainability plans, colleges and universities and other institutions renewed their environmental initiatives around sustainability, communities like Baltimore created sustainability commissions. There was definitely a participation boost.
We can categorize participation as external or internal:
- External: "ambassador" programs that engage with patrons, treating the park campus as an outdoor classroom and holding workshops for students, events like Montgomery County's GreenFest
- Internal: planting trees, doing park clean ups, conducting citizen science projects like measuring water quality in Parley's Creek
Sugar House Park has a "Garden Center," that has been under-active. We can reposition it around Gardening and the Environment, add a slew of activities and programs, making it a leading node within a network of top notch outdoor education centers in the Salt Lake Valley.
