Description: The Lower Santa Ana River Reach 5, 6 & 8 Landscape and Erosion Control project included four (4) basic features:
1st: Clear and Grub Approximately 8 miles, 4.5 million square feet, of existing river front park, debris removal, brush and ground cover clearing, tree trimming and removal, mulching and recycling.
2nd: Cap and abandon old irrigation systems. Correct and upgrade existing irrigation systems. New installation of over 1.5-miles of new 3” mainline, 15,000 lineal feet of lateral line with over 15,000 new sprinkler heads were included, as well as the construction of new concrete v-ditches, reinforced concrete structures, metal and wood fence, electrical feeds, controller and hot-tap water points of connection.
3rd: New landscaping includes planting and maintaining over 15,000 new plants, 1,000,000 square feet of hydro-seed areas, installation of 10,000 tons of decomposed granite over and along 15 miles of hiking, biking and equestrian trails.
4th: Erosion control, as part of the Storm water prevention Plan. CJW is installing 14,000 tons of 12”-24” Rip Rap landscape stone for both aesthetics & erosion control on the slope portions of the park and over 100 large ornamental stones will be positioned for aesthetics and focal points throughout the project. Approximately 10,000 cubic yards of recycled “green waste” mulch will be spread over two (2) million square foot.
Outstanding CCASS Evaluation from Owner
Challenges: After a third party investigation was conducted, it was determined that the stone called out in the specifications would not best meet the needs of this project. Thus, CJW located and submitted for approval a different more expensive, but better quality of stone to support this project. The rock was hard to find, but was given to the USACE at no additional cost and was placed within the timeframe allocated for project completion. Additionally, this project was successfully completed during the second wettest seasons ever recorded.
