A. The local planning commission shall prepare and recommend a comprehensive plan for the physical development of the territory within its jurisdiction and every governing body shall adopt a comprehensive plan for the territory under its jurisdiction.
In the preparation of a comprehensive plan, the commission shall make careful and comprehensive surveys and studies of the existing conditions and trends of growth, and of the probable future requirements of its territory and inhabitants. The comprehensive plan shall be made with the purpose of guiding and accomplishing a coordinated, adjusted, and harmonious development of the territory that will, in accordance with present and probable future needs and resources, best promote the health, safety, morals, order, convenience, prosperity, and general welfare of the inhabitants, including the elderly and persons with disabilities.
The comprehensive plan shall be general in nature, in that it shall designate the general or approximate location, character, and extent of each feature, including any road improvement and any transportation improvement, shown on the plan and shall indicate where existing lands or facilities are proposed to be extended, widened, removed, relocated, vacated, narrowed, abandoned, or changed in use as the case may be.
B. 1. As part of the comprehensive plan, each locality shall develop a transportation plan that designates a system of transportation infrastructure needs and recommendations that include the designation of new and expanded transportation facilities and that support the planned development of the territory covered by the plan and shall include, as appropriate, roadways, bicycle accommodations, pedestrian accommodations, railways, bridges, waterways, airports, ports, freight corridors, and public transportation facilities. The plan shall recognize and differentiate among a hierarchy of roads such as expressways, arterials, and collectors. In developing the plan, the locality shall take into consideration how to align transportation infrastructure and facilities with affordable, accessible housing and community services that are located within the territory to facilitate community integration of the elderly and persons with disabilities. The Department of Transportation shall, upon request, provide localities with technical assistance in preparing such transportation plan.
2. The transportation plan shall include a map that shows road and transportation improvements, including the cost estimates of such road and transportation improvements from the Department of Transportation, taking into account the current and future needs of residents in the locality while considering the current and future needs of the planning district within which the locality is situated.
3. The transportation plan and any amendment to such plan pursuant to § 15.2-2229 shall be consistent with the Commonwealth Transportation Board's Statewide Transportation Plan developed pursuant to § 33.2-353, the Six-Year Improvement Program adopted pursuant to subsection B of § 33.2-214, and the location of routes to be followed by roads comprising systems of state highways pursuant to subsection A of § 33.2-208. The locality shall consult with the Department of Transportation to assure such consistency is achieved. The transportation plan need reflect only those changes in the annual update of the Six-Year Improvement Program that are deemed to be significant, new, expanded, or relocated roadways.
4. Prior to the adoption of the transportation plan or any amendment to such plan, the locality shall submit such plan or amendment to the Department of Transportation for review and comment. The Department of Transportation shall conduct its review and provide written comments to the locality on the consistency of the transportation plan or any amendment to the provisions of subdivision 1. The Department of Transportation shall provide such written comments to the locality within 90 days of receipt of the plan or amendment, or such other shorter period of time as may be otherwise agreed upon by the Department of Transportation and the locality.
5. The locality shall submit a copy of the adopted transportation plan or any amendment to such plan to the Department of Transportation for informational purposes. If the Department of Transportation determines that such plan or amendment is not consistent with the provisions of subdivision 1, the Department of Transportation shall notify the Commonwealth Transportation Board so that the Board may take appropriate action in accordance with subsection F of § 33.2-214.
6. If the adopted transportation plan designates corridors planned to be served by mass transit, as defined in § 33.2-100, a portion of its allocation from (i) the Northern Virginia Transportation Authority distribution specified in subdivision B 1 of § 33.2-2510, (ii) the commercial and industrial real property tax revenue specified in § 58.1-3221.3, and (iii) the secondary system road construction program, as described in Article 5 (§ 33.2-351 et seq.) of Chapter 3 of Title 33.2, may be used for the purpose of utility undergrounding in the planned corridor, if the locality matches 100 percent of the state allocation.
7. Each locality's amendments to its transportation plan shall be made on or before its ongoing scheduled date for updating its transportation plan.
C. The comprehensive plan, with the accompanying maps, plats, charts, and descriptive matter, shall show the locality's long-range recommendations for the general development of the territory covered by the plan. It may include:
1. The designation of areas for various types of public and private development and use, such as residential, including age-restricted housing, tiny homes, or accessory dwelling units; business; industrial; agricultural; mineral resources; conservation; active and passive recreation; public service; and flood plain and drainage.
