Construction Monitoring Report for the Week of 20 April 2008 Dear Marci: Planning Systems is conducting ongoing monitoring of the construction activities associated with the grading for the Robertson Ranch West - Park Site and Habitat Corridor project to assure that all required biological mitigation measures are being implemented and performed correctly. This letter report documents the results of the construction monitoring activities and describes any issues that may be identified as a result of these monitoring activities. Planning Systems biologist Seth Schulberg is the primary construction monitor, with Greg Evans serving as back up if needed. Table I - Monitoring Schedule and Construction Activities Observed Date Time Monitor Construction Activity 25 Apr. 1400 -1600 S. Schulberg Grading has started for the El Camino Real Lane expansion Fill placement on the habitat corridor slope has started Head and wing-wall construction taking place for north desiltation basin outlet. Berm removed at mouth of El Camino Real Culvert in preparation for cleanout This grading was started for the El Camino Real lane expansion project, which will create the right-of-way for an additional northbound lane. As part of this activity the berm blocking the ECR culvert was removed to allow future cleanout of the culvert. Fill placement to reduce the slope of the habitat corridor continued. Construction started on the head-wall and wing-walls for the North desiltation basin discharge pipe. Weather did not affect construction activities this week. Planning Systems standard operating procedures for construction monitoring require keeping a written log of field notes with photo documentation as appropriate. Issues as they are identified and corrective actions as required are discussed with the owner's representative and the 1530 FARADAY AVENUE • SUITE 100 • CARLSBAD, CA 92008 • (760) 931-0780 • FAX (7160) 931-5744 • info@plamiingsystems.net construction site supervisor.

Planning Systems note that flow in the creek has.stopped. The only flow in the creek seems to be the intermittent presence of urban or landscape irrigation runoff from the project to the east. At this stage the majority of the natural habitat has been removed from the project site which will reduce the need for routine biological monitoring. During this, the fifteenth week of construction, Planning Systems conducted a single site visit to assure that construction activities are conducted per the requirements of the Monitoring, Mitigation and Reporting Program (MMRAP). No deviation from the MMRAP requirements was observed. Please feel free to call me (760) 931-0780 x 108 if you have any questions or require additional information.

Schulberg Grubbing continues along ECR where right-of-way for an additional lane is being created. This week vegetation removal and grubbing activities were initiated along the east side of the El Camino Real right-of-way as the initial step in the permitted ECR lane expansion phase of this project. Alluvium removal has been completed at the base of the habitat corridor slope. With removal of alluvium complete, placement of fill material can commence to reduce the slope of the habitat corridor. The temporary creek crossing used to grade the park site was removed and relocated east in the area where the permanent creek crossing will be constructed.

The temporary grade level crossing used to construct the park pad was removed and relocated to the east where it will provide access for the habitat grading, El Camino Real expansion and wetland restoration components of the project. . The new temporary crossing is in the area where the permanent crossing will be constructed.
