About this file
This is an Independent Cost Estimate (ICE) document prepared by the Orange County Transportation Authority (OCTA) for tree maintenance and pruning services. The procurement covers tree trimming, removal, stump grinding, and palm tree skinning services across OCTA properties, including new locations at the OC Streetcar and MSF facilities. The scope includes approximately 960 trees for trimming, 15 trees for removal and stump grinding, and 30 palm trees for skinning (600 linear feet). The contract term is two years with an option term date of October 1, 2025. The requisition number is R000690, and the contract replaces the expiring Agreement C-53855 (expiring March 31, 2026).
The total estimated cost for the two-year contract period is $210,600.00, calculated at an annual cost of $105,300.00 based on historical billing data under the existing agreement. Unit prices reflect $90 per tree for trimming, $300 per tree for removal and stump grinding, and $24 per linear foot for palm tree skinning. This is a prevailing wage contract, and the cost estimate is based on historical average billing rates from Agreement C-53855 covering approximately 760 trees, with additional estimated costs for approximately 200 new trees at the specified locations. The estimate was prepared by Christine Herrera, Contracts Analyst, and submitted to Contracts Administration & Materials Management (CAMM) for procurement processing.
