• Project Background
• Construction Summary
• Monitoring Equipment Installation
• Monitoring Period
Data presented today represents the initial results of monitoring the
system for a brief period of time. As this is a pilot project, long-
term results and conclusions will be used to inform future projects,
and guide improved analyses and design practices.

Monitoring Season (7/23/14 - 11/18/14)
![Page 27: Initial Monitoring Results and Performanceuppersanpedropartnership.org/wp-content/uploads/2017/10/...•Project Background •Construction Summary •Monitoring Equipment Installation](https://reader033.fdocuments.net/reader033/viewer/2022052013/602aa789ce32730a5422d54e/html5/thumbnails/27.jpg)
• Average summer and late frontal storms = Wet Summer season
• Stormwater runoff was less than modeled:
• Lower intensity storms
• More upland and channel infiltration?
• System captured and recharged water:
• Detention Basin did not overflow primary outlet structure
• Upstream In-Channel Basins captured the majority of the flow
• All stormwater delivered to the system was captured
• Estimated capture of 36 acre-feet during the monitoring period
• Infiltration trenches and drywells filled and drained rapidly

• 5-7 years of continued monitoring are recommended to capture variability in precipitation:
• Additional data will improve understanding of:
• Rainfall/Runoff relationships
• Efficiency of basins, drywells and infiltration basins
• Groundwater response
• Funding Source Unknown
• Ballpark annual inspection & monitoring costs will be around $55K
• Potential cost savings if
County performs some tasks
