The - Builder shall meet or exceed all mitigation commitments listed. The Department discourages creating RFP 11-10

11 additional exceptions and increasing the magnitude of the existing approved exceptions, and will not consider exceptions for modest benefits. The Department may consider further exceptions from standards or criteria on a case-by-case basis, at specific locations where the -Builder demonstrates that substantial benefit to the Department and the public would accrue from the recommendation. The -Builder shall obtain the Department s approval of any such changes to the standards or criteria. The -Builder shall fully and clearly document any changes from the standards and criteria and maintain a complete record of all such changes for the Department reference Exceptions to Mandatory Standards Mandatory standards use the word shall and are printed in bold face type in the HDM. The -Builder shall design all elements associated with mainline highway and other roadways in accordance with the criteria established in the Contract Documents Some design exceptions to the mandatory standards have already been approved by the Department and FHWA and are described in Table The -Builder shall submit additional or revised design exceptions to mandatory standards for their design for approval by the Department and the FHWA. The -Builder is discouraged from creating additional mandatory design exceptions, since there is no assurance that they will be approved by the Department or FHWA; however, elimination of existing design exceptions by the -Builder is encouraged. If the -Builder s design creates additional design exceptions or revises a previously approved exception, the -Builder must demonstrate on a case-bycase basis that substantial benefits to the Project and the public would result from the -Builder s recommendation. Any additional exceptions or revisions to previously approved exceptions requested by the -Builder will be subject to the Department and FHWA approval. The -Builder shall comply with the Exception Process as stated in Chapter 21 of the Project Development Procedures Manual (PDPM). The -Builder shall submit the request for design exception to the Department Headquarters Reviewer for review. If acceptable, the Reviewer then makes a recommendation to the Department Headquarters Coordinator for approval of the design exception. Once approved by the Coordinator, the Department will forward the exception request to FHWA for approval on the 13 controlling criteria if required (See Index of the HDM). This process could take approximately three to six months. The -Builder shall strive to enhance the geometric features of the Project and eliminate or minimize the design exceptions. The -Builder should be cautioned that merely eliminating design exceptions without regard to the impacts to the overall design may not be considered an enhancement or benefit to the project. Each improvement to the design exceptions, when taken as a whole, shall provide an overall benefit to the traveling public over the existing or proposed conditions. Table 11-1 presents nine Mandatory Exceptions that have been approved.

The proposed median between B Line and C Line from B Line Station to the end of the construction varies from 22 ft to 10 ft. The proposed mainline curves ( C and B Line) between SR 710 and Ocean Boulevard provide less than standard horizontal clearance Exceptions to Advisory Standards Advisory standards use the word should and are indicated by Underlining in the HDM. The -Builder shall design all the elements associated with mainline highway and other roadways in accordance with the criteria established in the Contract Documents. However, some advisory design exceptions have already been approved by the Department and are described in Table The -Builder shall submit additional or revised design exceptions for approval by the Department. The -Builder is discouraged from creating additional advisory design exceptions, since there is no assurance that they will be approved by the Department; however, elimination of existing design exceptions by the -Builder is encouraged. If the -Builder s design creates additional design exceptions or revises a previously approved exception, the -Builder must demonstrate on a case-by-case basis that substantial benefits to the Project and the public would result from the -Builder s recommendation.

13 Any additional exceptions requested by the -Builder will be subject to Department approval. The format and requirements of the Advisory Exceptions shall follow the format and requirements of the Mandatory Exceptions as stated in Chapter 21 of the PDPM with the exception that the Advisory Exceptions only need the Department s District approval. The Department Headquarters and FHWA approval are not necessary for an Advisory Exception. Upon receipt of the design exception request, the Department will review and if deemed acceptable, approve the request. This process could take approximately two to four months. The -Builder shall strive to enhance the geometric features of the Project and eliminate or minimize these design exceptions. The -Builder should be cautioned that merely eliminating design exceptions without regard to the impacts to the overall design may not be considered an enhancement or benefit to the project. Each improvement to these design exceptions, when taken as a whole, shall provide an overall benefit to the traveling public over the existing or proposed conditions.
