What is a Zoning Ordinance?

The zoning plan refers to the further arrangement of land use, population distribution, public facilities, and the allocation of urban infrastructure based on the overall urban planning. After the urban master plan is completed, large and medium-sized cities can compile zoning plans as needed. The zoning plans should be carried out simultaneously in the urban area. The zoning should be coordinated in a timely manner during the compilation process. The boundaries of the zoning area should be determined according to the group layout of the overall plan, combined with the administrative divisions such as urban districts and streets, and natural features such as rivers and roads.

After the urban master plan is completed, large and medium-sized cities can prepare zoning plans as needed. Small cities generally do not need to prepare zoning plans. The task of zoning planning is to make further planning arrangements for urban land use, population distribution, and the allocation of public facilities and infrastructure on the basis of the overall plan to provide a basis for detailed planning and planning management. Therefore, zoning planning plays a role as a link between the master plan and the detailed plan. In addition to meeting the specific requirements for planning, its specific requirements can be increased or deepened depending on the specific conditions of each city. ^[1]

The zoning plan should include the following:

(1) The principle stipulates the land use nature, residential population distribution, construction and land use capacity control indicators within the zone;

(2) determining the distribution of public facilities at the city, district, and residential level and their land use ranges;

(3) Determine the red line positions, sections, control point coordinates and elevations of the city's major and minor arterial roads, determine the direction and width of the branch roads, and the locations and control areas of major intersections, squares, and parking lots;

(4) Determine the green space system, the water surface of rivers and lakes, the corridors of high-voltage power supply lines, external transportation facilities, land boundaries of scenic spots, and the locations and control areas of major intersections, squares, and parking lots;

(5) Determine the location, orientation, pipe diameter, service scope, and location and land use scope of major engineering facilities.

The results of urban zoning planning include planning documents and drawings. The planning documents include planning texts and attachments, planning instructions and basic information and income attachments. The drawings mainly include: planning zoning map, zoning status map, zoning land use planning map, various professional planning maps, and the scale of the drawings is 1/5000.

Contents of the zoning plan text

(1) General principles: The basis and principles for planning.

(2) The principle of zoning land use and the division of different use nature lots.

(3) Control indicators such as population capacity, building height, and plot ratio within each zone are listed in the land use balance sheet.

(4) The planned red line position of roads (including the main and secondary arterial roads) and the coordinates and elevations of control points.

(5) Requirements for the protection and management of green areas, rivers and lakes, high-pressure corridors, cultural relics and historical sites.

(6) Planning requirements for engineering pipeline networks and major municipal utilities. ^[2]

Zoning plan drawing

(I) Plan the location map

The scale is not limited and represents the location of each district in the city.

(II) Current Situation of Districts

The drawing scale is 1/5000 and the content is:

1. The current status of land use is classified and plotted. The depth is mainly based on the medium category in the "Urban Land Classification and Planning and Construction Land Standard", supplemented by small categories.

2. City-level, district-level and residential district-level central location and scope;

3. Important place names, street names, and main unit names.

(Three) the land use planning map

The drawing scale is 1/5000 and the content is:

1. The planned boundaries of various types of land, the depth is the same as the current situation map;

2. The planned location and area of the city-level, district-level and residential district-level centers;

3. Green areas, rivers and lakes, high-pressure corridors, cultural relics and historic sites, land use boundaries and protected areas;

4. Important place names and street names.

(IV) Capacity planning plan for district buildings

Indicate control indicators such as building height and floor area ratio, and zoning boundaries;

(V) Road Plaza Planning Plan

1. Plan the directions, red lines, and sections of the main and secondary arterial roads and branches, the coordinates and elevations of the main control points;

2. Main road intersection forms and land use ranges;

3. The location of the main square, the parking lot and the scope of land use.

(6) Planning drawings of various engineering pipeline networks

According to the needs, the status, planned pipeline location, direction, diameter, and service scope of the project are divided into majors, and the location and land use scope of major engineering facilities are indicated.
