Section 710.403 - Management(a) As provided in § 710.201(h) , FHWA and SDOT may use their Stewardship/Oversight Agreement to enter into a written agreement establishing which approvals the SDOT may make on behalf of FHWA, provided FHWA may not assign to the SDOT the decision to allow any ROW use agreement or any disposal on or within the approved ROW limits of the Interstate, including any change in access control. The assignment agreement provisions in § 710.201(h) and this paragraph do not apply to non-SDOT grantees.(b) The grantee must ensure that all real property interests within the approved ROW limits or other project limits of a facility that has been funded under title 23 are devoted exclusively to the purposes of that facility and the facility is preserved free of all other public or private alternative uses, unless such non-highway alternative uses are permitted by Federal law (including regulations) or the FHWA. An alternative use, whether temporary under § 710.405 or permanent as provided in § 710.409 , must be in the public interest, consistent with the continued operation, maintenance, and safety of the facility, and such use must not impair the highway or interfere with the free and safe flow of traffic (see also 23 CFR 1.23 ). Park and Ride lots are exempted from the provisions of this part. Park and Ride lots requirements are found 23 U.S.C. 137 and 23 CFR 810.106 .(c) Grantees shall specify procedures in their approved ROW manual or RAMP for determining when a real property interest is excess real property and may be disposed of in accordance with this part. These procedures must provide for coordination among relevant State organizational units that may be interested in the proposed use or disposal of the real property. Grantees also shall specify procedures in their ROW manual or RAMP for determining when a real property interest is excess and when a real property interest may be made available under a ROW use agreement for an alternative use that satisfies the requirements described in paragraph (b) of this section.(d) Disposal actions and ROW use agreements, including leasing actions, are subject to 23 CFR part 771.(e) Current fair market value must be charged for the use or disposal of all real property interests if those real property interests were obtained with title 23, United States Code, funding except as provided in paragraphs (e)(1) through (6) of this section. The term fair market value as used for acquisition and disposal purposes is as defined by State statute and/or State court decisions. Exceptions to the requirement for charging fair market value must be submitted to FHWA in writing and may be approved by FHWA in the following situations:(1) When the grantee shows that an exception is in the overall public interest based on social, environmental, or economic benefits, or is for a nonproprietary governmental use. The grantee's ROW manual or RAMP must include criteria for evaluating disposals at less than fair market value, and a method for ensuring the public will receive the benefit used to justify the less than fair market value disposal.(2) Use by public utilities in accordance with 23 CFR part 645.(3) Use by railroads in accordance with 23 CFR part 646.(4) Use for bikeways and pedestrian walkways in accordance with 23 CFR part 652.(5) Uses under 23 U.S.C. 142(f) , Public Transportation. Lands and ROWs of a highway constructed using Federal-aid highway funds may be made available without charge to a publicly owned mass transit authority for public transit purposes whenever the public interest will be served, and where this can be accomplished without impairing automotive safety or future highway improvements.(6) Use for other transportation projects eligible for assistance under title 23 of the United States Code, provided that a concession agreement, as defined in § 710.703 , shall not constitute a transportation project exempt from fair market value requirements.(f) The Federal share of net income from the use or disposal of real property interests obtained with title 23 funds shall be used by the grantee for activities eligible for funding under title 23. Where project income derived from the use or disposal of real property interests is used for subsequent title 23-eligible projects, the funds are not considered Federal financial assistance and use of the income does not cause title 23 requirements to apply.
