The purpose of this action is to give vendors the opportunity to resubmit a proposal due to ambiguity within the requirements. Specifically, these updates were made within the Sections L and M documents. One point of clarification is the total page count for the Volume II.

The SBPCD Fillable form (Attachment #7) shall be included in its entirety and it will not count towards the total page count. All fillable portions of the form shall be completed by the Offeror. Other than the fillable fields, completed by the Offeror, the form shall not be tailored or modified in any way. Finally, clarifying potential contradictory language within Section M. The language in Section M, Section 1, Paragraph 2, is amended to change the 'may' statement to a 'shall' to align with. language in Section M, Section 2.1.2. Any resubmission will supersede the original submitted proposal for consideration under this Request for Proposal. Therefore, any vendor who resubmits their proposal in light of this clarification must resubmit the entirety of their proposal, to include all volumes and/or attachments as described in Section L, for consideration.
