COSCA is seeking proposals for the control of Russian thistle ( Salsola species) at four (4) work sites. Opportunistic treatment of other invasive non-native species is not anticipated, other than as noted in Task 3. Project sites are distributed throughout COSCA's open space system (Figure 1) and described in detail in the project scope of work. The extent of the treatment area at each location is illustrated in Figures 2 – 5. Treatment is to occur in the order that tasks are listed in the scope of work. Water is not available at any of the treatment locations so the contractor should plan accordingly. The selected entity for the project shall demonstrate prior experience with non-native plant management projects, shall be highly proficient in native and non-native plant identification, and shall possess a valid C-27 Landscape Contractor License from the state of California. Treatment methodology will entail spot application of herbicide. The contractor shall be licensed by the California Dept. of Pesticide Regulation (CDPR) as a Pest Control Operator, and the individual(s) applying the treatment shall possess a Qualified Applicator’s License or Certificate (QAL/C) from CDPR, or be under the direct supervision of a QAL/C. Tank mixes shall include a non-ionic surfactant (e.g., Agridex) and a photodegradable marking dye to facilitate visual confirmation of the extent of the application area by the applicator.

City of Thousand Oaks in Thousand Oaks, California is using this solicitation to procure consulting work. Public buyers typically advertise this kind of work as an Invitation for Bids (IFB), Request for Proposals (RFP), or Request for Qualifications (RFQ), depending on whether the selection is price-driven, qualifications-driven, or both.

Contracts of this type are usually awarded under the issuing agency's published procurement rules, with bid bond, performance bond, and reference requirements set in the solicitation documents. PublicBidSearch indexes this solicitation alongside other open bids in California so contractors and vendors can compare active opportunities by category, agency, or location without monitoring each procurement portal individually.
To submit a bid for this IFB, review the full solicitation documents for City of Thousand Oaks's exact scope of work, submission format, and any mandatory pre-bid meeting or site visit.
