- 2. Zoning • Zoning is the term used for designating permitted uses of certain parcels of land by local governments. • Zoning regulations typically divide a municipality (such as a city) into residential, commercial, and industrial zones.
- 3. Zoning • Land Zoning is the demarcation of geographic areas with specific combinations of properties or features used as per criteria only. • Land Zoning is the process of planning for land use by a locality to allocate certain kinds of structures in certain areas.
- 4. PURPOSE Theoretically, the primary purpose of zoning is to segregate uses that are thought to be incompatible. In practice, zoning is used to prevent new development from interfering with existing residents or businesses and to preserve the "character" of a community.
- 6. Importance of Zoning • Competition for diverse uses of land resources, the tremendous increase of population, natural and man-made hazards, economic opportunities and ecological hot spots call for distinctive and sustainable land management arrangement through the development of land use zoning in the country. • The Government of Bangladesh realizes this need and formulates different policies, strategies and planning documents making special reference to different coastal issues and its integrated management.
- 7. Outcomes of Zoning Task •Land use based upazilla-wise zoning maps for agriculture, fisheries, forestry, tourism, rural and urban settlements, industrial and commercial areas and other land uses for obtaining optimum economic benefits •Development of land resources database and land zoning information system •A detailed land zoning report covering all features and attributes of the project area
- 8. Outcomes of Zoning Task • Reports on community based information, social and environmental impact assessment • Comprehensive reports on char land and ecological critical areas of the project • Draft report on Land Zoning Law.
- 9. Objectives of land zoning • To ensure planning of proper utilization of land and soil potentials of particular area in order to maximum economic return. • To maintain bio-diversity in the area. • To grow awareness amongst planners, users, policy, makers and decision makers for rational utilization of land resources.
- 10. Zoning Parameters • To sustain land quality • Appropriate cropping pattern • Environmentally balanced • Scientifically sustainable • Economically viable • Socially acceptable, etc.
- 11. Purpose of Land Zoning Law • The purpose of the Zoning Law is the enforcement of the land zoning done. • Thus the law would also depend on how a parcel or parcels of land is categorized in the zoning map as, say for example, permitted, conditional or accessory etc. uses for a particular zone labeled with specific typology. • It is presumed that the law would have to follow even the Zoning codes and terminology used in preparing the Zoning map.
- 13. Micro Zones • Agricultural Zone • Fisheries Zone • Forest Zone • Urban Zone • Commercial and Industrial Zone • Char Land and Ecologically Critical Area • Haor-baor Areas • Barind Zone • Tourism and Historical Importance Areas • Forest Zone • Others

Editor's Notes
- The kind of features which are chosen and the interpretation of their different combinations depend on the purpose of the zoning exercise. The land zoning could be considered as one of the tools to help government in integrated planning and sustainable management of land resources of the country.

- The word is derived from the practice of designating permitted uses of land, based on mapped zones which separate one set of land uses from another.
- Zoning is a purely a state, county, city, or municipal affair. The land zoning should permit the following parameters:
- Agricultural: Agricultural zoning includes lands earmarked for production of crops, livestock and fisheries. Industrial: Industrial zoning is for manufacturing and warehousing operations. Residential: Residential zoning is for individual family units or groups. It includes single-family homes, duplexes, condominiums, trailer parks, and apartments. If the building you want to use for your business is zoned “residential” you will need to get a variance to use the property for business purposes. Commercial: Commercial property includes almost everything that is not residential, from offices to retail stores, to shopping malls and strip malls, to bars and nightclubs. Most professional offices are zoned commercial.
- Also known as "Building Block" zoning, Euclidean zoning is characterized by the segregation of land uses into specified geographic districts and dimensional standards stipulating limitations on the magnitude of development activity that is allowed to take place on lots within each type of district. Typical types of land-use districts in Euclidean zoning are: residential (single-family), residential (multi-family), commercial, and industrial. Uses within each district are usually heavily prescribed to exclude other types of uses (residential districts typically disallow commercial or industrial uses). Some "accessory" or "conditional" uses may be allowed in order to accommodate the needs of the primary uses. Dimensional standards apply to any structures built on lots within each zoning district, and typically, take the form of setbacks, height limits, minimum lot sizes, lot coverage limits, and other limitations on the building envelope. Euclidean zoning is preferred by many municipalities, due to its relative effectiveness, ease of implementation (one set of explicit, prescriptive rules), long-established legal precedent, and familiarity to planners and design professionals. Euclidean zoning has received heavy criticism, however, for its lack of flexibility and institutionalization of now-outdated planning theory. Separation of uses contributes to wasteful sprawl development, loss of open space, heavy infrastructure costs, and reliance on the automobile.
- Most modern zoning codes contain elements of the various approaches introduced above. They often employ traditional Euclidean zoning districts (especially in single-family residential areas) while applying performance zoning standards to more intensely-developed neighborhoods. They also tend to introduce incentive zoning to reduce parking and create affordable housing, while implementing form-based regulations in denser downtown areas. This modern practice of combining philosophies is often referred to as Hybrid zoning—an approach that identifies the best elements of each practice and integrates them into a new whole. Modular (or ‘Composite’) zoning is a specific type of hybrid zoning. It takes three fundamental components of development—use, form, and orientation—and mixes and matches them to create a wide variety of zoning districts.
- Like the previous techniques, Incentive zoning uses Euclidean zoning as a baseline. Yet to permit greater diversity and flexibility within those Euclidean zones, incentive zoning enables projects to exceed standard requirements if they provide some form of benefit to the local community. For example, in exchange for providing amenities (like parks, plazas, transit access, public art, or affordable housing), projects are usually allowed to build at higher densities or to greater building heights than are typically allowed. In many cases, this balancing act between development and community improvement occurs through a discretionary process that attempts to match the intensity of additional development to the scale and quality of the benefits provided. This can require significant staff time to determine.
- One of the newer interpretations of land-use planning, Form-Based zoning regulates development by focusing on the scale, design, and placement of buildings, paying particular attention to their relationship with the street (or other public spaces).
