COMCOR 49.28.01 Context Sensitive Road Design Standards
APPLICABILITY: This new regulation applies to all projects except as follows:
   1.   All capital projects already included in the Adopted CIP FY 09-14, except those projects listed in Facility Planning Transportation, are exempt from these regulations. Projects listed in Facility Planning Transportation which have completed Facility Planning Phase I including review of the project prospectus by the Council Transportation and Environment Committee by the date of adoption of these regulations are also exempt from these regulations, except that they shall comply with the Stormwater Management provisions of these regulations.
   2.   Development Projects - All development projects that have received preliminary plan approval by the date of adoption of these regulations are exempt from these regulations.
   3.   These Standards together with those existing design standards maintained by the DOT (Standards 100.01 - 811.01) are available for use until such time as the existing design standards are reviewed for applicability and either retained or eliminated. DOT will review the existing design standards for applicability within 12 months of the adoptions of these regulations to determine which standards should remain in place and which elements of the existing standards should be incorporated into the new standards. Additionally, details such as paving sections and general notes will be updated. A new Executive Regulation will then be submitted identifying which of the existing standards are to be eliminated.
