Linda Pennington | City Heights Community Organizer

Linda Pennington came on board as the City Heights Community Organizer in June 2012 with 30 years of experience organizing cleanups in the City Heights Community. With a Bachelor of Science Degree in Art Education including majors in art and education from the University of Houston and two years’ experience teaching high school art, Linda’s background positioned her to lead her community to make improvements in the neighborhood environment. Her first foray into the canyon work was her own canyon rim property in the Azalea Park Neighborhood in 1981. Initially, fire safety issues led her to organize Project CLEAN and lead neighbors to clean hazardous brush and debris from area canyons. Project CLEAN also took on graffiti, transient camps and advocating for community improvements. She began contracting with Community HousingWorks in 2006 to be the Project Manager for two FaceLift events per year where volunteers converge on a City Heights block and clean up, landscape and paint a dozen homes in one day. The City Heights scene has also offered many opportunities over the years to lead the community to acquire public art including the colorful Euclid Tower enhancements, art incorporated into the City Heights Weingart Library, carved wood Azalea Park street signs and numerous murals. Project CLEAN has been a major canyon partner to San Diego Canyonlands for several years. As the SDCL City Heights Community Organizer, Pennington will be able to continue her life work of improving City Heights and protecting City Heights’ urban canyons.
