Site Visit: September 9, 2026 Date Issued: September 17, 2026

The following questions were received from prospective bidders at the optional site visit held on September 9, 2026 and by email during the question period, together with clarifications OPRHP is issuing on the RFQ. Answers are provided below and are issued as part of the RFQ record for FHB2026B.

Where an answer clarifies or expands on the original RFQ language, the answer below applies.

Treatment area, density, and mapping

1. The RFQ describes the 17-acre area as greater than 75% invasive shrub cover and the ~66-acre area as less than 10% cover, but the released map appeared to show the reverse. Which is which?

The 17.0-acre area is the high-density area. It has invasive shrub cover exceeding 75%. It is the treatment priority. The remaining 66.58 acres is the low-density area and has 10% invasive shrub cover.

The map and legend included in the originally released RFQ conveyed the two densities backwards. A corrected map is issued with this document (Figure 1), and the RFQ figure has been updated accordingly. The invasive-shrub percent-cover heat map is also provided (see Question 5).

2. How will crews know when they have exited the high-density area?

The high-density area is easy to recognize on the ground. The change from the dense shrub understory to nearly bare-ground open woodland is abrupt, so crews will be able to tell readily when they have moved out of the high-density area into the surrounding low-density area.

3. Does the high-density area follow a distinct vegetation zone?

Yes. The 17-acre high-density area corresponds to the distinct dense-shrub vegetation zone, which transitions abruptly to open, low-density woodland at its edge. The mapped boundary reflects that zone.

4. When was the pre-treatment survey conducted?

The pre-treatment survey and mapping were conducted in late summer 2025 (approximately August 2025).

5. Can the heat map be shared?

Yes. The invasive-shrub percent-cover heat map is being provided to all prospective bidders together with this question-and-answer document (Figure 2), so bidders can review documented shrub cover ronda.williamson@parks.ny.gov Highlight across the treatment area before quoting. The heat map is georeferenced; OPRHP will provide the georeferenced map to the winning bidder.

6. What are the typical site conditions within the project site? I.e. is it typically wet, what kind of slope is there, etc.

The site is composed of a hardwood forest ranging from flat to moderate slopes. The north edge of the site has a bluff edge, where the treatment area ends. The site is dry, with some seasonally wet areas that are only inundated in spring. This site is subject to lake effect snow, which may complicate access when present during the treatment period since the service road will not be plowed.

Target species and identification

7. Are the privets included?

Yes. Border privet (Ligustrum obtusifolium) is on the target species list and is included. Consistent with the RFQ, all target invasive woody shrubs, and any other non-native woody shrubs encountered within the mapped treatment areas, are to be cut and stump-treated.

8. A specific barberry on site appeared very small. Is it too small to cut?

Japanese barberry is a target species and is included. Whether a given plant is cut follows the stem-size guidance in Question 8: stems large enough to cut cleanly and cut-stump treat (roughly ½ inch in diameter or larger) should be cut and treated; a very small stem below about ½ inch does not need to be cut-stumped under this contract. So a very small barberry may be left, while barberry of treatable size should be cut and treated.

9. Will mock orange (Philadelphus coronarius) be added to the list of species to be treated?

Yes. Mock orange (Philadelphus coronarius) is a target species and is to be cut and stump-treated.

OPRHP is in the process of obtaining the FIFRA Section 2(ee) recommendation for Garlon 4 Ultra, the preferred triclopyr herbicide, to cover mock orange for this treatment. If you intend to use a different triclopyr product, you are responsible for confirming that your product carries all of the FIFRA Section 2(ee) recommendations necessary to treat every target species on this site, including mock orange, at your own expense.

Cutting and treatment methods

10. What is meant by “short stuff”? Is there a stem size too small to bother cutting, around ½ inch in diameter?

There is no maximum size limit; all larger material is to be cut and stump-treated. Very small stems are the exception. Cut-stump treatment does not reliably control stems under about ½ inch in diameter, and stems that small are difficult to cut cleanly with a brush saw, so they do not need to be cut-stumped under this contract. Park staff can address those separately. Focus the work on the stems that can be cut and treated effectively. Cut stumps as close to the ground as practical (ankle height or lower) and treat the full cut surface, consistent with the RFQ.

11. What is the average DBH of target species within the project area?

The average stem diameter of target shrubs in the treatment area is 1 inch.

Access and public safety

12. Can crews walk the high-density area edge along the bluff trail?

Yes, the bluff trail may be used to reach and work the edge of the high-density area. Use caution: as noted in the RFQ, the bluff edges are steep and may be unstable. All personnel must remain upslope of steep edges, maintain safe working distances from drop-offs, and follow the terrain-appropriate safety and fall-protection measures the contractor is responsible for providing. Coordinate access and routes with park staff in advance.

Post-treatment verification

13. When will the post-treatment survey be performed, and what does it check?

Post-treatment verification will be conducted by the Finger Lakes Regional Biologist, generally within one to two weeks after treatment is completed. The assessment confirms that the target shrubs have been cut and that indicator dye is present on the cut stump surfaces, which demonstrates each stump was treated. If the treated area is fully cut and every stump shows indicator dye, the work is considered complete. This is consistent with the RFQ, which requires indicator dye on all cut stumps and sets an expected performance standard of approximately an 80% reduction in target invasive shrub stem density.

Procurement and bid terms

14. Are there MWBE (Minority- and Women-Owned Business Enterprise) requirements for this procurement?

No. There are no MWBE participation goals established for this procurement.

15. Does prevailing wage apply? The released RFQ contained a prevailing-wage paragraph, but the “Not Applicable” box was checked.

Prevailing wage does not apply to this procurement; the “Not Applicable” selection is correct.
