The Solicitation cited in block 9A above, Newlands Project Irrigation Facility Surveys for Lahontan Basin Area Office (LBAO) is hereby amended.

Purpose: The purpose of this amendment is to provide answers to received questions.

Question 1. It doesn't seem to show distances on each segment; do you want just a T&M price for field locations?

Answer 1. The length of each segment is provided in the GIS shapefiles. We can also provide the lengths in a spreadsheet if needed.

We prefer to keep the contract at a firm-fixed price.

Question 2. Do you want/need County recordable maps prepared, "Records of Survey" or maps/exhibits for the recording of the easements. Those would usually be 8 1/2 x 11 or

11 x 17, a "Record of Survey" map would be 24 x

36.

Answer 2. Yes, we would like maps/exhibits prepared for County recordation.

Question 3. What is the approximate size of each of the facilities?

Answer 3. The length of each segment is provided in the GIS shapefiles. The width of each feature is located in the Irrigation

Facility Surveys spreadsheet. If needed, we can provide the length of each feature segment to the spreadsheet.

Question 4. Is it an entire drain system or just headwall structures?

Answer 4. The system is comprised of canals, ditches and drains.

Question 5. A lot of facilities were underwater in the past. Is the expectation to provide bathymetric surveys?

Answer 5. The canals are offline from approximately November 15th through March 15th and can be surveyed (in the ditch) during that time period.

Question 6. Does this requirement require all survey deliverables to be performed and/or stamped by a licensed Professional Land

Surveyor, or is there room within the scope for aerial mapping and drone-based survey support as part of the deliverables?

Answer 6. A drone would be beneficial for establishing centerline as long as corners are established to define where the easement starts and stops. Any survey maps/legal description must be stamped and signed by a licensed PLS.

Please note, the submission deadline for quotes remains unchanged and is set for May 14, 2026, at 11:00 AM Pacific Daylight Time.

The contractors must acknowledge this amendment by submitting a signed copy of the Standard

Form (SF)-30 along with the quote.
