ITB #S63500-00006127

Mt Richmond Oak Habitat Improvement Project

Q. 1: it states a rubber-tired skid steer. Is a rubber tracked skid steer viable as an alternative?

2: on page 18 it says 284 acres, can I assume this is a typo and supposed to be 20 acres of opening up and 28 acres to be sprayed?

A. 1. A rubber tracked skid steer is actually preferred for better traction on the 20.6-acre project area.

2. Yes, I believe that to be an error. 284 acres is the total acreage for the entire property. 20.6 acres will be opened up and 28 acres are to be sprayed.

Q. 1. a. Could a pre-bid visit be arranged? When? Sere below.

b. If not pre-bid visit, do you have pictures of the site's listed in the scope of work?

2. Once the project is started is there a max number of days allowed on property to complete? See below.

3. Attachment D - Mandatory Bid Proposal form; due date says March 16th? Will you be updating this form to March 28th and submitting an addendum? Yes

4. Attachment D - Item No. 1 The Approx Quantity includes the entire property.

a. Could the scope of work potentially Increase? If so, how long would the contractor be required to honor quoted price? NO

b. Mastication(20.6 acres) and Spraying(28 acres) are identified as 2 separate projects. However, you are asking for a combined price per acre rather than separately? See reply below.

5. Will there be a Bid Bond required? NO

a. Liquidated damages? NO

b. Maintenance? NO

6. Will there be a Performance Bond required? NO

7. Do you have GPS coordinates for the areas shown on the map? See below.

A. 1. a. Could a pre-bid visit be arranged? When? We prefer not to host a site visit.

b. If not pre-bid visit, do you have pictures of the site's listed in the scope of work? I have included pictures below.

2. Once the project is started is there a max number of days allowed on property to complete? There is no max, but the project must be completed by June 30th.

7. Do you have GPS coordinates for the areas shown on the map? These may not be the exact areas, but very close to them. 45.394787, -123.253925, 45.393310, -123.255406

8. Will there be access to a water source for the purpose of filling the spray tank mounted on the quad? We prefer the contractor supply their own water.

Q. Do you have the EPA Registration number for the Stinger herbicide( active ingredients aminopyralid and metsulfuron-methyl) required for the project? We have only been able to find one Stinger herbicide with an EPA Registration number of 62719-73 but the active ingredient is Clopyralid.

A. Here's the EPA number (EPA Reg. No. 62719-73) and attached label. The contractor is correct that the only active ingredient in Stinger is Clopyralid. This is the chemical we would want to use since it doesn't harm most native broadleaf plants.

I believe ingredients aminopyralid and metsulfuron-methyl were listed in the application by mistake as these are the active ingredients for a chemical named opensight (EPA Reg. No. 62719-597) that harms all broadleaf plants.

Q .It appears from the project description that there is only about 48 acres of treatment area some masticating and some spraying, but in the Attachment D price proposal the listed number is 284 acres with no price differentiation between spraying or masticating. Can you please clarify?

A. The whole property is 284 acres; however, the treatment area is about 48 acres. We would like one price for the 48 acres that includes both spraying and masticating.

Below is some language directly from the label. Note: This is not a CRP site, but this is most applicable to site.

" Conservation Reserve Program (CRP) for Seeding to Permanent Grasses Only Do not use Stinger if legumes or bentgrass are a desired cover during CRP. Conditions of plant stress, such as drought, will increase potential for injury to grasses at all stages of growth. Do not apply to newly seeded areas until grass is established. Application Timing: Apply Stinger when perennial grasses are well established as indicated by vigorous growth and development of tillers and secondary roots. At this stage, most perennial grasses have shown adequate tolerance to Stinger. For optimum results, apply prior to the flowering stage (still in the bud stage). 11 Specimen Label Revised 12-13-22 Application Rate: For control of actively growing weeds, such as Canada thistle, knapweed (spotted, diffuse, and Russian), and musk thistle, apply 2/3 to 1 1/3 pints of Stinger per acre after the majority of basal leaves have emerged up to bud stage. For control of musk thistle rosettes, volunteer sunflower, and wild buckwheat, apply 2/3 pint of Stinger per acre. For best results, use in 10 gallons or more of water per acre by ground. Increasing the application rate increases the risk of injury. "

Q 1. What is the application rate of Stinger per acre?

A From my experience 1 pint per acre is sufficient. In the past we have had success treating with as little as 2/3 pint per acre.

2. Is on-site water available?

Yes, but it's preferred that the contractor supply their own water source.

3. Riparian is mentioned in the ITB. Is there a confirmed riparian on site?

No streams are present in the treatment areas but there are some springs and wet draws that may need to be avoided.

4. Avoiding steep terrain is also mentioned. Terrain would determine which piece of spraying equipment is used.

Majority of each unit is sloped. An atv will be needed.

Are we able to schedule a walkthrough of the property (prior to March 22) to get a better idea of the project for bidding and equipment options?

5. If not, will the homeowner provide additional photos?

Unit 4

Unit 5

Note: Unit 4 is a past photo that shows the site has been mowed. Neither unit was mowed in 2022.
