The Planning Board and District Council may establish administrative procedures to implement the provisions of this Part. The procedures shall not conflict with the provisions of this Part or the Regional District Act.

Effective on: 1/1/1901

1. (a)
   Any plans which were adopted or approved in accordance with the legally prescribed procedures in effect at the time of the action shall remain effective until superseded or amended in accordance with the provisions of this Part.
2. (b)
   Any plan or plan amendment adopted by the Commission or Planning Board after July 1, 1974, shall not have legal effect until approved by the District Council, except as provided for in Section 27-259.

Effective on: 1/1/1901

1. (a)
   When Functional Master Plans (and amendments thereof) and General Plan amendments are approved after the adoption and approval of Area Master Plans, the Area Master Plans shall be amended only to the extent specified by the District Council in the resolution of approval. Any Area Master Plan or Functional Master Plan (or amendment) shall be an amendment of the General Plan unless otherwise stated by the District Council.
2. (b)
   The General Plan designates Centers, Corridors, and Corridor Nodes where growth is specifically targeted to capitalize on existing infrastructure by locating homes, jobs, and shopping close to transit services. Centers, Corridors, and Corridor Nodes are intended for a mix of higher intensity nonresidential and residential uses that are consistent with existing or planned investments in the public infrastructure, and should be served by multimodal transportation networks including transit services (rail or bus) and bicycle, pedestrian, and trail facilities.

   1. (1)
      Centers are designated as focal points for increased efforts to concentrate development that can take advantage of existing or future investments in high-capacity mass transit services. There are three levels of Centers: Metropolitan, Regional, and Community, categorized on the basis of existing or anticipated components and characteristics such as the presence of large government service or major employment centers, high-intensity commercial uses, high-density residential development, or public services and facilities. Mixed-use and transit-oriented development concepts are equally important for future planning and development of these Centers.
   2. (2)
      Corridors are established along key transportation routes where development and redevelopment of higher intensity residential and nonresidential mixed uses may be appropriate. Compatibility of higher intensity development along Corridors with existing communities is essential, requiring close attention to be paid to design and land use relationships within and surrounding each project. Corridors are defined by segments within each General Plan policy tier. Developed Tier Corridors generally contain a higher intensity of residential and nonresidential land uses and a greater mix of uses that are regional in scope. Developing Tier Corridors generally contain less intense residential and nonresidential land uses than Developed Tier Corridors, with a mix of uses that are more community-oriented in scope. No Corridor extends into the Rural Tier.
   3. (3)
      Corridor Nodes are designated locations along Corridors where the majority of development and redevelopment opportunities recommended for Corridors should occur. Corridor Nodes may consist of local centers or other appropriate locations within one-quarter mile of major intersections or major transit stops along the Corridor, and should be developed in concert with existing and planned investments in public infrastructure. The General Plan designates several limited access highways as Corridors in the Developed and Developing Tiers. These limited access highway Corridors constitute Corridor Nodes extending one-quarter mile from designated interchanges.
3. (c)
   Any Area Master Plan or Sector Plan may designate, delete, or amend Centers, Corridors, and Corridor Nodes. These actions constitute amendments to the General Plan unless otherwise stated by the District Council.
4. (d)
   Centers, Corridors, and Corridor Nodes may not be designated by individual application through the Zoning Map Amendment process or through the Development District Overlay Zone or Transit District Overlay Zone amendment procedures specified in Sections 27-548.26(b)(1) and 27-548.09.01(b)(1).

In addition, the preliminary plan shall be referred to the Prince George's County Health Department to collaborate with planning staff for a health impact assessment review identifying the potential effects on the health of the population, and the distribution of those effects within the population, as well as recommendations for design components to increase positive health outcomes and minimize adverse health outcomes on the community.
   2. (2)

   3. (3)
