Abdirahman Buul

Environmental Project Manager

Abdirahman Buul believes sustainability is essential for true progress to be made. He was born
in San Diego just 2 years after his parents came to America as refugees from Somalia. Growing
up in San Diego and witnessing our city’s evolution is what pushed him towards studying
sustainability, and to discover ways to benefit his community. He attended San Diego State
University, which presented him with several opportunities, one of the most notable being that
he was on a team called the SOULA Project that designed, constructed, and operated a
hydroponic greenhouse on campus which is still being used today. After graduating from SDSU
in 2018 he began his career journey. He was hired as an outdoor sustainability educator at
Olivewood Gardens and Learning Center. As an outdoor sustainability educator, he ran daily
workshops to various groups that ranged from school kids to adults on ways to lead more

sustainable lives. After Olivewood he was able to utilize the geographical information systems
knowledge he acquired at SDSU to excel at Asplundh Construction & Engineering working as
an electrical designer with San Diego Gas & Electric. His journey then led him to Groundwork
San Diego - Chollas Creek in 2020.

“If it’s not equitable, it’s not sustainable”

Since equity is one of the pillars of sustainability, can we truly say a city is moving towards a
more sustainable future if its neighborhoods aren’t treated equitably? There is no simple
solution to this answer but all real solutions have one similarity, they must begin and end with
the community. As the environmental project manager, Abdirahman aims to activate the voices
of those communities which aren’t usually heard, foster relationships that benefit the people,
and be a part of the change we wish to see in our neighborhoods. This is what makes him such
an integral part of the Groundworks climate-safe neighborhoods effort.

To improve the environment, economy and quality of life for residents in the Chollas Creek Watershed through new approaches to community and educational development

To link energy, economic, and health equity with environmental justice by improving water quality; developing alternative forms of energy and economy; and increasing the capacity of low-income communities to lead climate action

Groundwork San Diego-Chollas Creek was founded in 2007 at the request of the City of San Diego to lead the master plan for the Chollas Creek Watershed. Initial funding came from the Environmental Protection Agency and the California Endowment in recognition of the role the environment plays in the well-being of low-income citizens. The master plan, entitled the Chollas Creek Enhancement Program, was developed through extensive stakeholder collaboration that represented neighborhoods, community planning groups, nonprofits, and faith-based institutions across the watershed. Its vision was to recover the pre-urbanization beauty of the natural resources of the region through education, advocacy, and compelling environmental design. To this end, Groundwork as generated over $10 million in government and philanthropic funding and engaged thousands of volunteers and stakeholders.
