Inquiry #13: It is apparent that water pressure from adjacent mountain is forcing ground water up through the joints. A) Please confirm Caltrans believes joint seal will be effective and is feasible to install in this area. B) If Caltrans determines joint seal is required and feasible, best practices are to perform spall repair prior to sealing existing pavement. Please provide a method of payment if Caltrans will require spall repair prior to joint seal installation. C) Compression seal does not work in existing joints with wide or variable widths. Some of the existing, longitudinal joints on the project have wide separations. Please consider the use of asphalt or silicone sealant for the existing pavement.

Inquiry #19: Under Bid Items 28 Contractor-Supplied Biologist and 29 Natural Resource Protection Plan, regarding the protocol presence/absence survey for the Least Bell's Vireo: does this require the full protocol 8-site visits between April-July by a qualified biologist?
Inquiry submitted 12/04/2019
Response #1:No this does not require the full protocol. A preconstruction survey needs to be performed by the Contractor biologist
Response posted 12/05/2019
Response #2:Following our latest consultation with the US Fish & Wildlife Service, it has been determined that protocol surveys are required in order to determine presence/absence. Simply conducting one survey would not be to protocol and thus would not be accepted, which would thus require full time biological monitoring.
Upon completion of protocol surveys, if species is absent, further biological monitoring would not be required. If species is found, then buffer noted in special provision would be implemented.
This response overrides the prior one.

Inquiry #29: Regarding Bid Items 28 Contractor-Supplied Biologist and 29 Natural Resource Protection Plan, is the project under a Biological Opinion or does the biologist need to have their own permit for the species?

Response #1:Submitted for consideration
Response posted 12/11/2019
Response #2:Q. Regarding Bid Items 28 Contractor-Supplied Biologist and 29 Natural Resource Protection Plan, is the project under a Biological Opinion
A. The project is not under a biological opinion.
Q. or does the biologist need to have their own permit for the species?
A. The biologist would need to be permitted for presence absence surveys for Coastal California Gnatcatcher. The biologist would have to be well qualified for presence absence surveys for Least Bell's Vireo and permitted if they are found and nest monitoring is required.
The biologist should follow the USFWS presence/absence survey protocol
For Coastal California Gnatcatcher:
Coastal California gnatcatcher surveys shall be completed by permitted biologists if proposed projects contain coastal sage scrub, alluvial fan scrub, chaparral, or intermixed or adjacent areas of grassland and riparian habitats, and is located within the range of this species. The protocol should be followed for all surveys unless otherwise authorized by the Service in writing.
For Least Bell's Vireo:
Surveys should be conducted by a qualified biologist familiar with the songs, whisper songs, calls, scolds, and plumage characteristics of adult and juvenile vireos. These skills are essential to maximize the probability of detecting vireos and to avoid potentially harassing the species in occupied habitats.
A permit is not required for presence/absence surveys as long as current protocol is followed and tapes are not used.
A permit is required when conducting nest monitoring, using taped vocalizations to illicit responses during presence/absence surveys, or handling individuals. An individual must provide documentation of experience observing least Bell’s vireos in the wild (40 hours minimum), in a variety of localities (5 minimum)

Inquiry #31: Addendum 2 added specification 36-5.04 stating "The payment for Hot Mix Asphalt (Type A) Interlayer shall be paid as Hot Mix Asphalt (Type A)". Conversely, the description for the HMA interlayer as shown on the revised summary of quantity sheets still includes "(N)", indicating that it is a non-pay item.
Summary of Quantities plan sheet Q-6 indicates a total of 3,092 T of Hot Mix Asphalt (Type A) Interlayer and a total of 25,662 T of Hot Mix Asphalt (Type-A). If the above referenced specification is correct, the total quantity for bid item 390132 should be revised to 28,754 T.
