(M&A) to submit a proposal to provide restoration, monitoring, and maintenance services for the Batiquitos Slope Enhancement project located adjacent and within your property limits. The following scope and attached cost proposal address the work to be done for conducting the Coastal Sage Scrub restoration, monitoring and reporting, as well as maintenance work as required. Task 1: On-Site Preparation In order to meet project objectives, on-site preparations must occur before planting begins. Due to the inclusion of several non-desirable species in the original hydroseed application, revegetation technicians would scrape the existing hydroseed layer and dispose of off-site. This would allow the seed within the new application of hydroseed to become established with minimal competition from less desirable species. Additionally, the seed mix in the new hydroseed slurry is a more accurate representation of native plant species located in adjacent areas. At this time exotic and non-native species would also be disposed of off-site. Technicians would then adjust existing irrigation heads to ensure full coverage for the newly planted site. t • '.. . i Task 2: Planting M&A would provide al] of the materials, labor and supervision needed to re-vegetate the site. Planting efforts should occur as soon as possible to take advantage of seasonal rains that would facilitate establishment of seedlings and container plants. Revegetation technicians would plant container species which would be followed by a hydroseeded application of a native seed mix within the disturbed area. Seed application rates would vary based on the presence of sage scrub vegetation adjacent to the disturbed area. The hydroseeded mix should be placed into a slurry with a soil binder to facilitate initial growth and deter granivorous birds, mammals, and insects from devouring the seed mix. The fiber mulch and M-Binder would also provide enhanced erosion control properties of the slope. The proposed slurry mix is as follows: 01/09/02 WED 11:46 FAX 858 560 7779 . -• 'Mr-Hernandez \\ '• !>•'„' lj\\ i|003 M&A# 02-003-01 January 9,2002 Product Wood Fiber Muich M-Binder Fertilizer (15- 15- 15) Lbs./Acrc 2,000 100 200 . .

Seed collected from coastal San Diego County locations is recommended to fulfill the above requirements. Task 3: Monitoring and Reporting The restoration site would include an annual 3 year post-construction monitoring program with monitoring periods occurring at 0, 32, 24, and' 36 months after successful installation of plant materials. The objectives of the monitoring program would be to document and report the status of the restoration effort, as well as provide direction of maintenance activities. Monitoring would involve the use of transect surveys, survival counts, and fixed station photo-documentation.

The cover arid composition of the vegetation at the time of each reporting interval would be analyzed relative to the following success milestones: Milestone 0 Month 12 Months 24 Months 36 Months Assessment Criteria Iliiscline information; no coverage criteria; ail planting . densities achieved. . . (00% survival of all container plants. Coastal Sage Scrub vegetation cover totals at least 20%. 8f)% overall survival of all container plants materials. 'Coastal Sage Scrub vegetation cover totals at least 30%. 100% survival of all plants achieving 12 month milestone. Coasta! Sage Scrub vegetation cover totals at least 40%. 100% survival of al! plants achieving 24 month milestone and/or 65% cover. Maintenance Action Plant densities brought up to meet requirements. If cover or survival criteria fail to achieve minimum standards, plant densities will be brought up to 100%of the initial planting densities. • . If cover or survival criteria tail to achieve minimum standards, plant densities will be brought up to 100% of the initial planting densities. If cover criteria is not. met, additional planting \yill be performed to bring all areas up to initial planting densities. Reports would include an assessment of completed and necessary maintenance actions that would promote habitat establishment. Monitoring reports would be submitted to the City of Carlsbad Planning Department and U.S. Fish and Wildlife Service, as required. In addition to scheduled monitoring visits, general qualitative assessments of the site will be conducted periodically to direct maintenance activities throughout the duration of the enhancement program. These assessments would occur at 30, 60, and 90 days after completion of the installation of plant materials to ensure proper establishment of plant materials. Qualitative assessments will continue to be made at quarterly increments for the duration of the monitoring program: Task 4: Maintenance Maintenance activities would include weed species eradication, removal of debris, and replacement of dead or damaged plant materials. Maintenance visits would be scheduled twice per month for the first six months, monthly for the second six months, then quarterly thereafter until the conclusion of the three-year period. Please review this scope and attached cost proposal and let me know how you wish to proceed. Timing is ideal for implementing the program to take advantage of winter rains. We are happy to have the opportunity to continue to assist you on this site and look forward to hearing from you with respect to this proposal.
