Abstract/Summary
This senior project focused on planning, designing, and constructing drainage and pedestrian access improvements at City Farms SLO, a nonprofit in San Luis Obispo that promotes sustainable agriculture and youth education. Prior to construction, the site experienced significant stormwater pooling and erosion in a central area of the farm, making daily operations and visitor access difficult during wet weather. The team excavated an 80-foot trench drain with appropriate slopes, installed a 15-foot corrugated HDPE culvert with proper bedding and backfill, built a seven-foot pedestrian bridge over the trench, and created a 17-foot gravel pathway connecting the bridge to an existing deck. These upgrades effectively mitigated stormwater pooling and erosion while enhancing safe pedestrian access for visitors and program participants. Total costs were approximately $2,000, with much of the material secured through donor outreach, delivering immediate benefits including reduced maintenance and improved site usability. Key lessons included the importance of contingency planning for unexpected soil conditions and weather delays, the value of teamwork in managing physical demands, and the benefit of pursuing outside funding. Clear stakeholder communication proved essential in aligning expectations throughout the entire process.
