Who were the site visit attendees?

With another contractor working on the same street how will it be determined who is responsible for damage to the street?

Access to the site will be limited prior to the completion of the levee project, also removal of the trees will largely be completed by the levee contractor, therefore it is assumed that damage to the road will be the responsibility of the levee construction contractor. At the end of the levee contract the road will be repaired by the levee contractor and further damage would be the responsiblity of the revegetation contractor. This has been clarified in the PWS in section 9.c.x.

There is a disproportionate amount of Hordeum seed for Seed Mix C per Attachment D compared to Table A1 ‐ Attachment G. Please confirm the correct seed rates for

Seed Mix C.

Response: Seed mix C shown in Attachment D was incorrect and is corrected in the amendment. Also, Attachment G has been revised to clarify that the quantities of seed shown for each zone have been compensated to account for the portion of the zone taken up by the plant rows which are not seeded (about 4 feet of each 30ft row is not seeded.
