DRYCO built a cast-in-place concrete amphitheater and integrated retaining walls on a steep Oakland hillside, turning an unused slope into a durable gathering space.
Project Overview
The customer wanted tiered seating and safe access on a challenging, sloped site with long-term stability in mind. DRYCO’s concrete crews handled everything from initial grading through final seat walls and stairs, delivering a clean, modern amphitheater that ties into the surrounding landscape.
Scope of Work
- Site grading and excavation for stepped amphitheater layout
- Installation of grade beams and structural reinforcement
- Cast-in-place concrete seat walls and risers
- Concrete stairs and landings for multiple access points
- Drainage piping, subgrade prep, and engineered backfill
- Cast-in-place retaining walls to stabilize the hillside
Challenges & Solutions

FAQ
What was the main challenge when working on the hillside amphitheater?
The main challenge was the steep slope, which required careful grading, shoring, and precise concrete pouring to ensure safety and stability.
How does the slope affect concrete work on a hillside amphitheater?
A steep slope requires site grading, stabilization, and custom formwork to ensure structural integrity and safe access points.
How did DRYCO stabilize the hillside for the amphitheater?
DRYCO used cast-in-place retaining walls, custom formwork, and engineered backfill to stabilize the hillside and prevent erosion.
How do weather and site conditions influence when concrete can be poured?
Temperature and moisture are key. If it’s too hot or too cold, the curing process, whereby concrete gains strength, can be compromised. Also, on sloped or uneven terrain, site preparation, drainage considerations, and ground stabilization become more important. All these various factors influence whether concrete pouring should proceed.
How can I ensure the durability of my concrete project?
To ensure durability, use quality concrete materials, proper concrete pouring techniques, and allow for adequate curing time. Regular maintenance and ensuring proper drainage, also helps extend the lifespan of your project.
