Parent Power & �Green Schoolyards
LAUSD owns over 6,400 acres, the largest landowner in Los Angeles County.
The majority of these schoolyards are covered
in asphalt without any tree cover for shade.
Schoolyards are often the hottest location in �every neighborhood because they have little shade �and so many hot surfaces.

Asphalt in particular raises the air temperature because it not only �holds on to heat but it covers most of the surface area at each school.
+48 degree temperature difference

July 21st at 11:03 AM�Alta Loma Elementary School
+ 39 degree temperature difference
When the air temperature is raised due to human-created reasons, it is known as the heat island effect.
This means that if your
neighborhood has a lot of asphalt, it can be up to 20 degrees hotter
than a neighborhood that has less asphalt.
Asphalt changes the local climate.
Redlining Map of Los Angeles 1939
The urban heat island effect is disportionately worse in areas that experienced redlining. Redlining was the discriminatory practice of giving neighborhoods a grade, depending on their perceived ability to pay back loans, such as mortgages. Communities of color were usually given a grade D which was the color red in the map. This redlining also deterred government investment in parks and trees therefore reducing the value of land and often attracting heavy polluting industries.

These two maps reveal the correlation between areas �that have been redlined and higher temperatures.

Extreme heat exacerbates chronic illness
LATIMES 2021
"Heat affects the heart, it affects the lungs, it affects the kidneys, it affects your fluid balance. It can make diabetes worse; it can make psychiatric disorders worse."

200 schools in LAUSD do not have a single tree.
�Highlands Council of PTAs schools
Historically, trees have been planted around the perimeter, not directly on campus.
It IS possible for schools to look �& feel different
than they do now.

Planting trees can reduce the air temperature by 9 degrees
Capturing stormwater helps replenish groundwater and makes L.A. more drought resilient
Planting native plants invites pollinators and birds who keep our ecosystem in balance, which regulates our weather patterns
Dynamic outdoor learning allows students to experience their local environment first hand
Non-competitive play alternatives give kids more options at recess and after school

How can YOU as a
parent get involved?
Support UTLA in their effort to include �Climate Justice Demands �in their new contract!
How to advocate for green schoolyards at your school:
Campus assessment for low-hanging-fruit improvements: �
For larger improvements:
�- Eligible projects include depaving and planting trees, creating a garden area
�- Eligible schools need to capture a certain amount of water or partner with
schools to capture water as a network of schools
- Funding prioritizes nature-based solutions such as replacing pavement with
stormwater infrastructure such as bioswales, rain gardens, and cisterns and
creating a collaborative process with the community�
�-This initiative will work to increase tree canopy on public school grounds to shade and
protect PK-12 students from extreme heat and rising temperatures due to climate
change.
