Natural Treatment Site: Port Culver

Natural Treatment Site: Port Culver

 

Port Culver NTS siteThe Port Culver NTS basin is located just southeast of the corner of Culver and Portola Parkway.  Port Culver has yet to receive sufficient flows to warrant regular water quality monitoring. The site remains one of the driest NTS basins, and its established vegetation is on the drier side.  The primary surrounding land uses are mostly agriculture at the present time. 

It is anticipated that as future development fills in the surrounding watershed, enough dry weather flow can be sustained to allow a regular monitoring program. 

 

 

 

 Location & Size

ocation: 4201.75 Portola Parkway, Irvine
Size: 2.1 acres
Tributary Watershed: 243 acres
Status: On line, June 2008

 Biological Values


TThe site maintains below average biological values, as it is receives so little dry weather flows of water.  The surrounding land uses are primarily agriculture, however, across Portola Parkway, dense urban development is present.  The site may need to be re-seeded with wetland vegetation if future flows warrant monitoring, as little of the original wetland vegetation has survived. Additional wildlife observations are planned for the future. No bird species were observed as breeding on the site.

 Maintenance


Routine Maintenance Activities:

    • TruGreen LandCare provides routine irrigation and landscape maintenance services at the site. Additional work such as mulch replacement, irrigation repairs, aquatic herbicide application, aquatic vegetation removal, and sediment removal were performed throughout the year.
    • System operations staff performed weekly site inspection, water quality monitoring, and landscape and irrigation maintenance review.

Major Repairs: None during this fiscal year
Major Improvements: None during this fiscal year
