Section 710.307 - Construction advertising(a) The grantee must manage real property acquired for a project until it is required for construction. Except for properties acquired under the early acquisition provisions of 23 CFR 710.501(e) , clearance of improvements can be scheduled during the acquisition phase of the project using sale/removal agreements, separate demolition contracts, or be included as a work item in the construction contract. The grantee shall develop ROW availability statements and certifications related to project acquisitions as described in 23 CFR 635.309 .(b) The FHWA-SDOT Stewardship/Oversight Agreement will specify SDOT responsibility for the review and approval of the ROW availability statements and certifications in accordance with applicable law. Generally, for non-National Highway System projects, the SDOT has full responsibility for determining that right-of-way is available for construction. For non-SDOT grantees, FHWA will be responsible for the review and approval.
