    Description

    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.

    Background

    The Conejo Open Space Conservation Agency (COSCA) is a joint-powers agency formed in 1977 representing a partnership between the City of Thousand Oaks (City) and the Conejo Recreation and Parks District (CRPD) for the protection and stewardship of public open space land and trails. An integral part of COSCA’s mission is the stewardship and restoration of vital wildlife habitats and the preservation of biodiversity. Invasive plant species are a threat to ecological processes, native plant communities, and the persistence of native species. COSCA actively manages invasive species to promote the ecological functions of open space.

    • Project Background Information and Purpose

      Purpose:

      The scope of work outlined below is designed to accomplish the purpose of this RFP, namely to remove specific, targeted, plant species from the 4 project sites described in the scope of work using the prescribed methods and timing. There will not be a pre-bid job walk, however all project locations are open to the public. Prospective bidders may access these sites independently on-foot to confirm the scope of work.

      Prepare a proposal that addresses all tasks as outlined below to accomplish the same. Develop a timeline that describes the process and key milestones for completing the project on time and within budget. COSCA estimates the project will take less than 3 weeks from issuance of notice to proceed.

    • Scope of Work

      TASK 1:  Labisco Hill.  

      The target species is present in moderate densities throughout the treatment area, which was last treated in 2024.  Current work will consist of a continuation of site-wide treatment.  Foot access is available from the northern terminus of Dover Avenue.  The treatment area is illustrated in Figure 2.

      Methodology: Foliar application of triclopyr (e.g., Garlon).  Plants vary in size from small seedlings to individuals approaching maturity. 

      Deliverables:  Digital sketch of treated area extents.

       

      TASK 2:  Lang Ranch.

      The target species is present in scattered small patches throughout the treatment area, which was last treated in 2024.  The extent of the treatment area is based on aerial imagery and limited site reconnaissance.  Actual field conditions may vary slightly from the illustration in Figure 3.  Vehicular access is available from the Autumn Ridge trailhead at the northern terminus of Westlake Blvd.  Parking for one vehicle is available near the apex of the treatment location.

      Methodology:  Russian thistle - foliar application of triclopyr (e.g., Garlon).  Plants vary in size from small seedlings to individuals approaching maturity.

      Tree tobacco – cut stump application of triclopyr (e.g., Garlon).  Plants are generally large shrubs.  Biomass may be left on site to decompose.

      Deliverables:  Digital sketch of treated area extents.

       

      TASK 4:  Woodridge. 

      The target species is present in scattered small patches throughout the treatment area, which was last treated in 2024.  The extent of the treatment area is based on aerial imagery and limited site reconnaissance.  Actual field conditions may vary slightly from the illustration in Figure 5.  Foot access is available from Sunset Hills Blvd., via the Woodridge Loop trailhead.

In case of failure of the Successful Proposer to execute and return the contract and all required documents within the time allowed, the City may, at its option, consider that the Proposer has abandoned the contract, in which case the Proposal Security Bond, if one was required, shall be forfeited by the Proposer and become the property of COSCA.

    • Testing

      After delivery, random samples may be submitted to a commercial laboratory, or other inspection City, for testing to determine if they conform to the specifications. In cases where tests indicate the samples do not meet specifications, the cost of the testing shall be borne by the contractor. When tests indicate the materials do not meet specifications, the City reserves the right to cancel the award and purchase the goods in the open market at the expense of the Proposer.

    • Conflict Of Interest

      Proposer covenants that it presently has no interest, and shall not acquire any interest, direct or indirect, financial or otherwise, which would conflict in any manner or degree with the performance of the services hereunder.

    • Prevailing Wage and Apprenticeship

      The work described herein may be a “public work”, as defined in Labor Code Section 1771, thus obligating Contractor/Consultant and subcontractor to pay prevailing wages under the California Labor Code. Contractor/Consultant and subcontractor agrees to indemnify, defend and hold City harmless from any claim that prevailing wages should have been paid, and shall be liable for the payment of the same and any penalties thereon. It is the responsibility of the Proposer to be familiar with the California Labor Code, and failure or neglect of the Proposer to understand the California Labor Code shall in no way relieve him from any obligations. 

      Labor Code section 1777.5 requires the use of qualified apprentices by all trades, regardless of the dollar amount of their portion of the work, on public works contracts over $30,000. Apprentices shall be used at no less than the ratio required by law, and shall be paid at the prevailing wage for apprentices in the trade for which they are registered. It is Contractor/Consultant’s sole responsibility to ensure that they and their subcontractors comply with the specific requirements of section 1777.5.

      Successful Proposer shall fully warrant all materials and equipment furnished under the terms of this contract, against poor and inferior quality, for a period of not less than one (1) year from date of the final acceptance by the City.

      If a Proposal contains confidential information protected by a statutory exemption, a Proposer may clearly label that part of the Proposal as "CONFIDENTIAL" and list the statute which exempts the information from disclosure. The “CONFIDENTIAL” part of the Proposal shall be uploaded in the Vendor Questionnaire section, separate from the rest of the Proposal. If no part of the Proposal is segregated and marked confidential, the absence of such designation or marking shall constitute a complete waiver of all claims for damages caused by any release of the information.

During that time, it will be the duty of the Proposer to obtain a protective order of its labeled information. Failure to so act in that time shall constitute a complete waiver.

      If specific parts of the Proposal are claimed to be exempt by statute and if the Proposer obtains a protective order from a court of law, the City will withhold only those portions that are protected and disclose the remainder as required under the California Public Records Act.

      A Proposal labeled in its entirety as “CONFIDENTIAL” will be considered non-responsive and will not be considered.
