141-610: Rio Alamar or Arroyo de Alamar is a river mainly in northern Baja California , Mexico with a small portion in California , United States. The riparian corridor that is the Alamar has a wooded area home to: riparian, aquatic and migratory birds, abundant species of fish, and amphibians. The wildlife and natural vegetation in the Arroyo Alamar was historically a vital resource for fishing, bathing, and even drinking. The stream

282-497: A Consejo Nacional de Ciencia y Tecnología (Conacyt) investigator, a little under a million people were classified as "poor" in the state, up from 2008 when there were roughly 810,000. Exactly who these people are, whether locals, interstate or international migrants, was not explained. Baja California offers one of the best educational programs in the country, with high rankings in schooling and achievement. The state government provides education and qualification courses to increase

423-420: A 5.1-magnitude shaker at 4:14 am that was centered near El Centro . As of 6:31   am PDT on 5 April 2010, two people were confirmed dead. Baja California is subdivided into seven municipios (' municipalities '): Ensenada , Mexicali , Tecate , Tijuana , Rosarito , San Quintín and San Felipe . In Baja California, state elections are held every two years (every three years prior to 2019) for

564-638: A 7.2 M w   (on the moment magnitude scale ) magnitude northwest-trending strike-slip earthquake hit the Mexicali Valley , with its epicenter 26 km (16 mi) southwest of the city of Guadalupe Victoria, Baja California . The main shock was felt as far as the Los Angeles , Las Vegas , Phoenix and Tucson metropolitan areas , and in Yuma. At least a half-dozen aftershocks with magnitudes between 5.0 and 5.4 were reported, including

705-458: A PUD provides flexibility to create convenient ways for residents to access commercial and other amenities. In the US, residents of a PUD have an ongoing role in management of the development through a homeowner's association . Pattern zoning is a zoning technique in which a municipality provides licensed, pre-approved building designs, typically with an expedited permitting process. Pattern zoning

846-537: A bank trust property has the option to either remain within the trust or opt out of it and request the title in escritura . Mexico's early history involved foreign invasions and the loss of vast amounts of land; in fear of history being repeated, the Mexican constitution established the concept of the "Restricted Zone". In 1973, in order to bring in more foreign tourist investment, the Bank Trust of Fideicomiso

987-516: A combination of private and public planning. Other critics of zoning argue that zoning laws are a disincentive to provide housing which results in an increase in housing costs and a decrease in productive economic output. For example, A 2017 study showed that if all states deregulated their zoning laws only halfway to the level of Texas, a state known for low zoning regulations, their GDP would increase by 12 percent due to more productive workers and opportunity. Furthermore, critics note that it impedes

1128-593: A compact geographic area. The mixing of land uses is common throughout the world. Mixed-use zoning has particular relevance in the United States, where it is proposed as a remedy to the problems caused by widespread single-use zoning. Form-based or intensity zoning regulates not the type of land use, but the form that land use may take. For instance, form-based zoning in a dense area may insist on low setbacks, high density, and pedestrian accessibility. Form-based codes (FBCs) are designed to directly respond to

1269-404: A compatible group of uses are allowed to co-exist - or a combination of both single and mixed-use zones in one system. The main approaches include use-based, form-based, performance and incentive zoning. There are also several additional zoning provisions used in combination with the main approaches. Use-based or functional zoning systems can comprise single-use zones, mixed-use zones—where

1410-400: A compatible group of uses are allowed to co-exist —or a combination of both single- and mixed-use zones in one system. The primary purpose of single-use zoning is to geographically separate uses that are thought to be incompatible. In practice, zoning is also used to prevent new development from interfering with existing uses and/or to preserve the character of a community. Single-use zoning

1551-505: A free economy, as poor zoning restrictions hinder the more efficient usage of a given area. Even without zoning restrictions, a landfill, for example, would likely gravitate to cheaper land and not a residential area. Single-use zoning laws can get in the way of creative developments like mixed-use buildings and can even stop harmless activities like yard sales. The Houston example of non-zoning or private zoning with no restriction on particular land use but with other development code shows

1692-436: A given development may be granted. Zoning may specify a variety of outright and conditional uses of land. It may indicate the size and dimensions of lots that land may be subdivided into, or the form and scale of buildings. These guidelines are set in order to guide urban growth and development. Zoning is the most common regulatory urban planning method used by local governments in developed countries. Exceptions include

1833-407: A greater diversity of stakeholders also leads to better informed and shared agreements, actions, and outcomes. Increasing community participation in decision-making can also support effective policy implementation that leads to better environmental outcomes. A procedurally just approach for the region's urban and environmental governance has been at the forefront of environmental justice efforts. This

1974-456: A green corridor, and flood prevention and mitigation were urban-planning needs also included. These environmental services are crucial for sustaining water consumption of the settled communities within their 10.5 km section. Binational hydrological and hydrecological studies were conducted to analyze the importance of preservation and conservation of the Arroyo. High toxicity testing costs in

2115-584: A high degree of flexibility, but may be complex to administer. The more a proposed development takes advantage of incentive criteria, the more closely it has to be reviewed on a discretionary basis. The initial creation of the incentive structure in order to best serve planning priorities also may be challenging and often requires extensive ongoing revision to maintain balance between incentive magnitude and value given to developers. Incentive zoning may be most effective in communities with well-established standards and where demand for both land and for specific amenities

2256-753: A lack of capacity-building efforts meant key missing community members went unrecognized as needed stakeholders in Arroyo decision-making process. Key impediments to community participation in governance have been: lack of time, knowledge, funding, political influence, and impact perceptions. Another structural barrier is the high opportunity costs faced by marginalized groups from the time-space constraints of meeting everyday needs. Environmental capacity building for local communities requires taking into consideration participation barriers and ensuring outreach strategies consult even those lacking cultural, social, and political capital. Meaningful consultation under bottom-up and procedurally just governance values local knowledge in

2397-568: A lack of clean water access, deteriorating water quality, soil contamination, and health hazards. Prioritizing the siting of maquiladoras over critical basic facilities in Tijuana's land use development has led to the environmental degradation for both ecosystems and residents. Besides maquiladoras, other constructions include: recycling centers, manufacturing plants, traffic routes, and other polluting industries. The affluent household and industrial waste that runs downhill disproportionately exposes

2538-644: A large Chinese community, as well as many Filipinos who arrived to the state during the eras of Spanish Philippines and American rule (1898–1946) in much of the 19th and 20th centuries. Tijuana and Ensenada were major ports of entry for East Asians entering the U.S. ever since the first Asian Americans were present in California. According to the 2020 Census, 1.71% of Baja California's population identified as Black, Afro-Mexican , or of African descent. Since 1960, large numbers of migrants from southern Mexican states have arrived to work in agriculture (especially

2679-512: A low-level marine fog near the coast. The fog occurs along any part of the Pacific coast of the state. The change of altitude towards the Sierra de Baja California creates an alpine climate in this region. Summers are cool, while winters can be cold with below freezing temperatures at night. It is common to see snow in the Sierra de Juárez, Sierra de San Pedro Mártir and in the valleys in between

2820-424: A menu of compliance options where a property developer can earn points or credits for limiting environmental impacts, including affordable housing units, or providing public amenities. In addition to the menu and points system, there may be additional discretionary criteria included in the review process. Performance zoning may be applied only to a specific type of development, such as housing, and may be combined with

2961-575: A more sedentary lifestyle. The Cocopa and Quechan of northeastern Baja California practiced agriculture in the floodplain of the lower Colorado River . Another group of people was the Guachimis, who came from the north and created much of the UNESCO World Heritage -recognized Sierra de Guadalupe cave paintings . Not much is known about them except that they lived in the area between 100   BC and 1300   AD. Europeans reached

3102-407: A new scientific rationality, the advent of mass production and complex manufacturing, and the subsequent onset of urbanisation. Industry leaving the home reshaped modern cities. The definition of home was tied to the definition of economy, which caused a much greater mixing of uses within the residential quarters of cities. Separation between uses is a feature of many planned cities designed before

3243-431: A number of sub-categories, for example, within the commercial category there may be separate districts for small retail, large retail, office use, lodging and others, while industrial may be subdivided into heavy manufacturing, light assembly and warehouse uses. Special districts may also be created for purposes like public facilities, recreational amenities, and green space. The application of single-use zoning has led to

3384-422: A property owner and a local government to rezone a property in exchange for a commitment from the developer. It typically involves loosening restrictions on how the property can be used. Contract zoning is controversial and sometimes prohibited because it deviates from the broader planning process and has been considered an illegal bargaining away of the government's police powers to enforce zoning. Fiscal zoning

3525-418: A quasi-judicial process that enables land uses that, because of their special nature, may be suitable only in certain locations, or when arranged or operated in a particular manner. Uses which might be disallowed under current zoning, such as a school or a community center, can be permitted via conditional-use permits. Contract zoning is a controversial practice in which there is a bilateral agreement between

3666-425: A reduction in lot sizes. The term planned unit development (PUD) can refer either to the regulatory process or to the development itself. A PUD groups multiple compatible land uses within a single unified development. A PUD can be residential, mixed-use, or a larger master-planned community. Rather than being governed by standard zoning ordinances, the developer negotiates terms with the local government. At best,

3807-600: A single space. Mixed-use zoning can be vertical, within a single building, or horizontal, involving multiple buildings. Planning and community activist Jane Jacobs wrote extensively on the connections between the separation of uses and the failure of urban renewal projects in New York City. She advocated dense mixed-use developments and walkable streets . In contrast to villages and towns, in which many residents know one another, and low-density outer suburbs that attract few visitors, cities and inner city areas have

3948-584: A space for participation, analysis of information, and coordination among the actors involved. Its objective was to reach a consensus on the project for the completion of the Arroyo el Alamar channeling, bringing together the efforts of all stakeholders. On December 10 the MTAA formally collaborated with CONAGUA and the Government of the State of Baja California. CONAGUA committed to providing 160 million pesos, while

4089-585: A strong focus on tariff-free export oriented manufacturing ( maquiladora ). As of 2005, 284,255 people are employed in the manufacturing sector. There are more than 900 companies operating under the federal Prosec program in Baja California. In 2021, Baja California generated 57,550 new jobs, about 15.2 jobs per 1000 inhabitants, making it the 5th highest in the country and the second highest of any border state behind Nuevo León (86,364 new jobs). The majority of these new jobs were generated in and around

4230-531: A system of use-based districts. Performance zoning is flexible, logical, and transparent while offering a form of accountability. These qualities are in contrast with the seemingly arbitrary nature of use-based zoning. Performance zoning can also fairly balance a region's environmental and housing needs across local jurisdictions. Performance zoning balances principles of markets and private property rights with environmental protection goals. However, performance zoning can be extremely difficult to implement due to

4371-404: A true agricultural center . The Cerro Prieto geothermal province is near Mexicali as well (this area is geologically part of a large pull apart basin ); it produces about 80% of the electricity consumed in the state and enough additional power to export to California. Laguna Salada , a saline lake below sea level lying between the rugged Sierra de Juárez and the Sierra de los Cucapah, is also in

4512-434: Is a broad term that consists of several alternatives to use-based zoning that incorporate information and communication technologies. There are a number of different techniques to accomplish smart zoning. Floating zones, cluster zoning, and planned unit developments (PUDs) are possible—even as the conventional use-based code exists —or the conventional code may be completely replaced by a smart performance or form-based code, as

4653-425: Is a controversial practice in which a small part of a larger zoning district is rezoned in a way that is not consistent with the community's broader planning process. While a jurisdiction can rezone even a single parcel of land in some cases, spot zoning is often disallowed when the change would conflict with the policies and objectives of existing land-use plans. Other factors that may be considered in these cases are

4794-507: Is a controversial practice in which local governments use land use regulation, including zoning, to encourage land uses that generate high tax revenue and exclude uses that place a high demand on public services. Environmental activists argue that putting everyday uses out of walking distance of each other leads to an increase in traffic, since people have to own cars in order to live a normal life where their basic human needs are met, and get in their cars and drive to meet their needs throughout

4935-531: Is a method in which a municipality or other tier of government divides land into "zones", each of which has a set of regulations for new development that differs from other zones. Zones may be defined for a single use (e.g. residential , industrial ), they may combine several compatible activities by use, or in the case of form-based zoning, the differing regulations may govern the density, size and shape of allowed buildings whatever their use. The planning rules for each zone determine whether planning permission for

The name of the fish genus Bajacalifornia is derived from the Baja California peninsula. In the main wildlife refuges on the peninsula of Baja California, Constitution 1857 National Park and Sierra de San Pedro Mártir National Park , several coniferous species can be found. The most abundant are Jeffrey pine, Pinus ponderosa , Pinus cembroides , Pinus quadrifolia , Pinus monophylla , Juniperus , Arctostaphylos pringlei subsp. drupacea , Artemisia ludoviciana and Adenostoma sparsifolium . Baja California shares many plant species with

5217-616: Is a zoning district that overlaps one or more zoning districts to address a particular concern or feature of that area, such as wetlands, historic buildings or transit-oriented development . Overlay zoning has the advantage of providing targeted regulation to address a specific issue, such as a natural hazard, without having to significantly rewrite an existing zoning ordinance. However, development of overlay zoning regulation often requires significant technical expertise. Transferable development rights, also known as transfer of development credits and transferable development units, are based on

It flows generally west for about 25 kilometres (16 mi) through the San Ysidro Mountains and the Tijuana urban area before joining with the Arroyo de las Palmas in central Tijuana, to form the Tijuana River . The Rio Alamar tributary makes up almost one third of

5781-493: Is high. However, hidden costs may still offset its benefits. Incentive zoning has also been criticized for increasing traffic, reducing natural light, and offering developers larger rewards than those reaped by the public. Additional zoning provisions exist that are not their own distinct types of zoning but seek to improve existing varieties through the incorporation of flexible practices and other elements such as information and communication technologies (ICTs). Smart zoning

During the 2021 Mexican legislative election , six of the eight federal deputies representing Baja California in the Mexican Chamber of Deputies were won by Morena candidates, with the other two being won by candidates of the Labor and Ecologist Green parties. The next legislative elections are scheduled for 2024 . Although the state is more European in ancestry, it has historically seen sizable East and Southeast Asian immigrant population. Mexicali has

6063-547: Is steadily growing. Baja California has developed a need to be self-sufficient in matters of technological and scientific innovation and to be less dependent on foreign countries. Current businesses demand new production processes as well as technology for the incubation of companies. The number of graduate degrees offered, including PhD programs, is 121. The state has 53 graduate schools. As of 2005, Baja California's economy represents 3.3% of Mexico's gross domestic product , or US$ 21.996 billion. Baja California's economy has

The mineral-rich mountain range extends southwards to the Gulf of California, where the western slope becomes wider, forming the Llanos del Berrendo on the border with Baja California Sur. The mountain ranges located in the center and southern part of

6345-450: Is the ability to create flexible zoning districts for smoother transitions between adjacent properties with different uses. Inclusionary zoning refers to policies to increase the number of housing units within a development that are affordable to low and middle-income households. These policies can be mandatory as part of performance zoning or based on voluntary incentives, such as allowing greater density of development. An overlay zone

6486-404: Is the largest natural resource issue of the state. Baja California's climate varies from Mediterranean to arid . The Mediterranean climate is found in the northwestern corner of the state, where the summers are dry and mild and the winters cool and rainy. This climate is observed in areas from Tijuana to San Quintín and nearby interior valleys. The cold oceanic California Current often creates

The Todos Santos islands and Coronado Islands are located off the coasts of Ensenada and Tijuana, respectively. All of the islands in the Gulf of California on the Baja California side belong to the municipality of Mexicali. Baja California obtains much of its water from the Colorado River. Historically,

6768-428: Is used to reduce barriers to housing development, create more affordable housing, reduce burdens on permit-review staff, and create quality housing designs within a certain neighborhood or jurisdiction. Pattern zoning may also be used to promote certain building types such as missing middle housing and affordable small-scale commercial properties. In some cases, a municipality purchases design patterns and constructs

6909-741: Is where only one kind of use is allowed per zone, or district. It is also known as exclusionary zoning or, in the United States, as Euclidean zoning because of a court case in Euclid, Ohio , Village of Euclid, Ohio v. Ambler Realty Co. 272 U.S. 365 (1926), which established its constitutionality. It has been the dominant system of zoning in North America, especially the United States , since its first implementation. Commonly defined single-use districts include: residential, commercial, and industrial. Each category can have

The fauna in

7473-633: The New Urbanism movement. To accommodate the New Urbanist vision of walkable communities combining cafés , restaurants , offices and residential development in a single area, mixed-use zones have been created within some zoning systems. These still use the basic regulatory mechanisms of zoning, excluding incompatible uses such as heavy industry or sewage farms , while allowing compatible uses such as residential, commercial and retail activities so that people can live, work and socialise within

7614-525: The Republic of Baja California . The Mexican government forced his retreat after several months. When liberal army general Porfirio Díaz came to power in 1876, he embarked on a major program to develop and modernize Mexico. Baja California encompasses a territory within the Californias region of North America, which exhibits diverse geography for a relatively small area. The Peninsular ranges of

7755-616: The Roman Catholic Church retained too much power in the post-independence period and sought to undermine it by mandating the secularization of missions in 1833. In the aftermath of the Mexican American War (1846–1848) and the Treaty of Guadalupe Hidalgo , the United States gained sovereignty over territory previously held first by New Spain and then Mexico, most of which was sparsely settled. Alta California

7896-545: The United Kingdom and the City of Houston , Texas . Most zoning systems have a procedure for granting variances (exceptions to the zoning rules), usually because of some perceived hardship caused by the particular nature of the property in question. The origins of zoning districts can be traced back to antiquity . The ancient walled city was the predecessor for classifying and regulating land, based on use. Outside

An estimated 200,000+ American expatriates live in the state, especially in coastal resort towns such as Ensenada, known for affordable homes purchased by retirees who continue to hold U.S. citizenship. San Felipe, Rosarito and Tijuana also have a large American population (second largest in Mexico after Mexico City), particularly for their cheaper housing and proximity to San Diego. Some 60,000 Oaxacans live in Baja California. Some 40% of them lack proper birth certificates. According to

11139-634: The ability of those that wish to provide charitable housing from doing so. For example, in 2022, Gloversville's Free Methodist Church in New York wished to provide 40 beds for the homeless population in -4 degree weather and were inhibited from doing so. Corruption is a challenge for zoning. Some have argued that zoning laws increase economic inequality . Empirical effectiveness estimates show some zoning approaches can contribute to housing crisis . The legal framework for land use zoning in Australia

11280-550: The advent of zoning. A notable example is Adelaide in South Australia , whose city centre, along with the suburb of North Adelaide , is surrounded on all sides by a park, the Adelaide Park Lands . The park was designed by Colonel William Light in 1836 in order to physically separate the city centre from its suburbs. Low density residential areas surround the park, providing a pleasant walk between work in

11421-674: The applicable procedures. A total of twenty meetings, both online and in-person, were conducted throughout 2020–2021. Civil society organizations, members from the H.XVIII Tijuana City Council, the Environmental Protection Department, and IMPLAN were involved to coordinate and facilitate the management of various aspects related to the declaration. 32°30′56″N 116°58′22″W  /  32.5156°N 116.9729°W  / 32.5156; -116.9729 Baja California The state has an estimated population of 3,769,020 as of 2020, significantly higher than

11562-408: The area for environmental protection and restoration. This highlighted the sense of ownership among citizens and shed light on the necessity and significance of preserving spaces and ecosystems. On November 23, 2014, as a follow-up to the collaborative meetings between the government and society, the formal establishment of the "Mesa Técnica del Arroyo Alamar (MTAA)" took place. This platform served as

11703-405: The area when the agreement was annulled. Supported on such events the project "Sustainable Architecture of Arroyo Alamar, Tijuana, Baja California, Mexico'" (2005) proposed a conceptual design of a linear park. The SCERP linear park proposal sought to mitigate flooding risks, protect the stream's aquifer recharge processes, and reduce environmental impacts to the riparian and inhabited landscape. By

11844-568: The borders and coasts of Mexico by way of a trust handled through a Mexican bank (Fideicomiso). This trust assures to the buyer all the rights and privileges of ownership, and it can be sold, inherited, leased, or transferred at any time. Since 1994, the Foreign Investment Law stipulates that the Fideicomiso must be to a 50-year term , with the option to petition for a 50-year renewal at any time. Any Mexican citizen buying

11985-636: The case in London or New York. The construction of the Montparnasse Tower in 1973 led to an outcry. As a result, two years after its completion the construction of buildings over seven storeys high in the city centre was banned. Performance zoning, also known as flexible or impact zoning or effects-based planning, was first advocated by Lane Kendig in 1973. It uses performance-based or goal-oriented criteria to establish review parameters for proposed development projects. Performance zoning may use

12126-450: The channel of the Arroyo stream. Civil protection authorities have now classified the Alamar as susceptible to flooding due to mud flow and fast avenues. CONAGUA proceeded to request an agreement with the municipality that granted the federal agency the custody, conservation and maintenance over the administration of the channel and federal zone of the Arroyo Alamar. The state government would later monitor urban infrastructure work related to

12267-432: The cities of Tijuana , Mexicali , Ensenada , Playas de Rosarito , and Tecate . Industries that experienced the highest degree of growth in 2021 include transformative industries , transport and communication , commerce , and construction . As of November 2021, Baja California has the highest employment rate of any state in northern Mexico , with a rate of 96.7%. As of September 2021, Baja California receives

12408-482: The city of Miami did in 2019. The incorporation of ICTs to measure metrics such as walkability , and the flexibility and adaptability that smart zoning can provide, have been cited as advantages of smart zoning over "non-smart" performance or form-based codes. Floating zones describe a zoning district's characteristics and codify requirements for its establishment, but its location remains unspecified until conditions exist to implement that type of zoning district. When

12549-460: The city walls were the undesirable functions, which were usually based on noise and smell. The space between the walls is where unsanitary and dangerous activities occurred such as butchering, waste disposal, and brick-firing. Within the walls were civic and religious places, and where the majority of people lived. Beyond distinguishing between urban and non-urban land, most ancient cities further classified land types and uses inside their walls. This

12690-519: The city within and the family homes outside. Sir Ebenezer Howard , founder of the garden city movement , cited Adelaide as an example of how green open space could be used to prevent cities from expanding beyond their boundaries and coalescing. His design for an ideal city, published in his 1902 book Garden Cities of To-morrow , envisaged separate concentric rings of public buildings, parks, retail space, residential areas and industrial areas, all surrounded by open space and farmland. All retail activity

12831-456: The community's desired character and intensity of development. The French planning system is mostly form-based; zones in French cities generally allow many types of uses. The city of Paris has used its zoning system to concentrate high-density office buildings in the district of La Défense rather than allow heritage buildings across the city to be demolished to make way for them, as is often

12972-634: The complexity of preparing an impact study for each project, and can require the supervising authority to exercise a lot of discretion. Performance zoning has not been adopted widely in the US. Incentive zoning allows property developers to develop land more intensively, such as with greater density or taller buildings, in exchange for providing some public benefits, such as environmental amenities or affordable housing units. The public benefits most often incentivised by US cities are "mixed-use development, open space conservation, walkability, affordable housing, and public parks." Incentive zoning allows for

13113-427: The concept that with land ownership comes the right of use of land, or land development . These land-based development rights can, in some jurisdictions, be used, unused, sold, or otherwise transferred by the owner of a parcel. These are typically used to transfer development rights from rural areas (sending sites) to urban areas (receiving sites) with more demand and infrastructure to support development. Spot zoning

13254-403: The concrete channelization has ensued under the claims of reduced flooding and deterring illegal development along the river. The Arroyo Alamar experienced additional money-oriented land access struggles when concrete channelization replaced the prior eco-channelization plan. Government land in the Arroyo became invaded and resold under the claim of viable real estate development when the riverbed

13395-698: The context of inadequate social service allocations made such transborder collaborations critical. Some studies include: “Flood Hydrology of the Binational Cottonwood Creek-Arroyo Alamar, California and Baja California” (2001) and "Hydroecological Characterization of Arroyo Alamar, Tijuana, Baja California, Mexico" (2004) carried out by the Southwest Consortium for Environmental Research and Policy (SCERP) and “The Alamar River Corridor; an Urban River Park Oasis in Tijuana, Baja California, México”(2001) carried out by

13536-514: The criteria for implementation of a floating zone are met, the floating zone ceases "to float" and its location is established by a zoning amendment. Cluster zoning permits residential uses to be clustered more closely together than normally allowed, thereby leaving substantial land area to be devoted to open space. Cluster zoning has been favored for its preservation of open space and reduction in construction and utility costs via consolidation, although existing residents may often disapprove due to

13677-538: The day. Single-use zoning and urban sprawl have also been criticized as making work–family balance more difficult to achieve, as greater distances need to be covered in order to integrate the different life domains. These issues are especially acute in the United States, with its high level of car usage combined with insufficient or poorly maintained urban rail and metro systems. Some economists claim that zoning laws work against economic efficiency, reduce responsiveness to consumer demands and hinder development in

13818-555: The declaration of the conservation area of the Alamar stream. During 2020, the Colectivo Salud y Justicia Ambiental A.C. organized meetings and conducted field trips in the stream area, engaging with Councilors and directors from IMPLAN and the Municipal Directorate for Environmental Protection. In October 2020, a working technical group was established through IMPLAN to advance the declaration process and ensure its completion, approval, and subsequent publication following

13959-452: The deliberation processes that impact their environment. Actively promoting authentic and inclusive dialogue ensures the material and ideological foundations of a project, such as direction, scope, or operations, can be traced back to the influence of community input. The built-in accountability process of procedural just approaches to governance closes participation gaps and recognizes local concerns and priorities. Creating policy solutions with

14100-452: The distinctive form of many cities in the United States , Canada , Australia , and New Zealand , in which a very dense urban core , often containing skyscrapers , is surrounded by low density residential suburbs , characterised by large gardens and leafy streets . Some metropolitan areas such as Minneapolis–Saint Paul and Sydney have several such cores. Mixed-use zoning combines residential, commercial, office, and public uses into

14241-482: The environmental category of the identified strategies. MPLAN was then charged to carry out an Environmental Impact Study for the nearly ratified eco-friendly channelization design.The Arroyo restoration project with sustainable river architecture was finally signed off by municipal subcommittees in 2009. The project had planned restoration, recreation spaces, and permeable side walls and bottoms well-suited for natural filtration. Such sustainable urban development process in

14382-873: The fall of 2007 the Otay Mesa Binational Corridor Strategic Plan was drawn up and approved by the San Diego Association Board of Directors and the XVIII City Council of the City of Tijuana. Uniting the ''"Binational Vision of the Basin of the Tijuana River" and the Border 2012 programs for the creation of conservation areas particularly in the Arroyo Alamar were established recommendations within

14523-539: The first overland exploration of the northwestern portion of the state. The Dominicans took over management of the Baja California missions from the Franciscans in 1773. They established a chain of new missions among the northern Cochimí and western Yumans, first on the coast and subsequently inland, extending from El Rosario (1774) to Descanso (1817), just south of Tijuana below the Palóu Line . In 1804,

14664-554: The flood plain has also induced binational collaborations due to the close proximity of the Arroyo to the United States. The pollution and the environmental injustices that threaten the Rio Alamar are a result of many long-standing and deep-rooted factors including: transnational and national policies, prioritizing profit-based land use processes, industrial pollution, underdeveloped urban infrastructure in Tijuana, exponential population growth and migration, and stark division created by

14805-713: The larger bi-national Tijuana River Watershed that spans approximately 1,750 square miles and impacts the lives of more than 1.4 million people. The major tributary as part of the Tijuana River Estuary has been deemed one of the 21 wetlands of international importance by the RAMSAR Convention. The Rio Alamar and the Tijuana River's Watershed is threatened by pollution and is the site of active rehabilitation and environmental justice efforts that are combined with urban planning in this region.   The lack of proper planning and regulation that contaminated

14946-560: The major wine-producing area in Mexico. To the east of the mountain range, the Sonoran Desert dominates the landscape. In the south, the weather becomes drier and gives way to the Vizcaíno Desert . The state is also home to numerous islands off both of its shores. Baja California is also home to Guadalupe Island , the westernmost point of Mexico. The Coronado Islands , Todos Santos islands , and Cedros Island are also on

15087-478: The more expensive eco-friendly Arroyo project were also removed. Concrete channelization alone risks habitat destruction, species endangerment, loss of surface and groundwater, increased erosion, magnified pollution concentrations, and aggravated local flood events.  The concrete channelization approach for developing urban planning in the Arroyo instead made more money for the city and state. Against environmental, binational, and community wishes eco-channelization

15228-587: The north, including the Kiliwa , Paipai , Kumeyaay , Cocopa , and Quechan . These peoples were diverse in their adaptations to the region. The Cochimí of the peninsula's Central Desert were generalized hunter-gatherers who moved frequently; however, the Cochimí on Cedros Island off the west coast developed a strong maritime economy. The Kiliwa, Paipai, and Kumeyaay in the better-watered northwest were also hunter-gatherers, but that region supported denser populations and

15369-430: The parks include a large number of mammals, primarily mule deer , bighorn sheep , cougars , bobcats , ringtail cats , coyotes , rabbits , squirrels and more than 30 species of bats . The park is also home to many avian species like bald eagles , golden eagles , falcons , woodpeckers , black vultures , crows , and several species of Sittidae and duck . At 3:40:41 pm PDT on Easter Sunday, 4 April 2010,

15510-427: The physical structure of a community in order to create more walkable and adaptable environments. Form-based zoning codes have five main elements: a regulating plan, public standards, building standards, and precise definitions of technical terms. Form-based codes recognize the interrelated nature of all components of land-use planning—zoning, subdivision, and public works—and integrate them to define districts based on

15651-485: The positions of state governor , 25 state deputies of the Congress of Baja California , and 5 municipal mayors. Of the 25 state deputies, 17 are elected by relative majority in each of the electoral districts, while another 8 are elected by proportional representation. The 17 deputies elected by relative majority may be re-elected for up to four consecutive terms, while the other 8 deputies can only serve one term. During

15792-472: The present state of Baja California in 1539, when Francisco de Ulloa reconnoitered its east coast on the Gulf of California and explored the peninsula's west coast at least as far north as Cedros Island. Hernando de Alarcón returned to the east coast and ascended the lower Colorado River in 1540, and Juan Rodríguez Cabrillo (or João Rodrigues Cabrilho (in Portuguese) ) completed the reconnaissance of

15933-423: The problem of maintaining order between strangers. This order is maintained when, throughout the day and evening, there are sufficient people present with eyes on the street . This can be accomplished in successful urban districts that have a great diversity of uses, creating interest and attracting visitors. Jacobs' writings, along with increasing concerns about urban sprawl, are often credited with inspiring

16074-513: The properties themselves while in other cases the municipality offers the patterns for private development. A hybrid zoning code combines two or more approaches, often use-based and form-based zoning. Hybrid zoning can be used to introduce form and design considerations into an existing community's zoning without completely rewriting the zoning ordinance. Composite zoning is a particular type of hybrid zoning that combines use, form, and site design components: An advantage of composite zoning

16215-522: The recognized area in the stream for riparian forest conservation purposes.Throughout 2018 and early 2019, the Colectivo Salud y Justicia Civil Association Environmental A.C. (formerly known as the Chilpancingo pro Justicia Ambiental collective) continued their efforts from previous work and studies. They held meetings with the Directors of IMPLAN to secure the required support for the preparation of

16356-459: The recorded cases of lupus, anencephaly, and gastrointestinal disorders in the Arroyo region that resulted from industrial contamination and a lack of basic services. Alleviating the environmental and social grievances of affected communities in the Arroyo requires community participation and procedural justice in the region's environmental governance. As such, having a 'place at the table' of the decision-making processes of IMPLAN's management plan for

16497-437: The resources of the nation-state, and exacerbated socio-economic disparities. As a result, the overburdened structures of environmental and social governance of the region did not have the mechanisms for enforcing sufficient outreach to its disadvantaged communities. The programmatic scope of Tijuana's municipality has frequently been unable to create meaningful relationships with marginalized populations. Minimal participation from

16638-596: The river drained into the Colorado River Delta and then flowed into the Gulf of California, but due to large demands for water in the American Southwest , less water now reaches the Gulf. The Tijuana metropolitan area also relies on the Tijuana River as a source of water. Much of rural Baja California depends predominantly on wells, a few dams and even oases. Tijuana also purchases water from San Diego County's Otay Water District. Potable water

16779-473: The site of active environmental justice, conservation, and land use community development planning efforts for nearly two decades. Various neighborhoods located within the Arroyo Alamar united with representatives from Tijuana's Human Rights office in November 2005 to advocate for the health risks of inhabitants associated with environmental contamination of the stream. The citizen movement brought attention to

16920-621: The size of the parcel, the zoning categories involved, how adjacent properties are zoned and used, and expected benefits and harms to the landowner, neighbors, and community. Conditional zoning is a legislative process in which site-specific standards and conditions become part of the zoning ordinance at the request of the property owner. The conditions may be more or less restrictive than the standard zoning. Conditional zoning can be considered spot zoning and can be challenged on those grounds. Conditional zoning should not be confused with conditional-use permits (also called special-use permits ),

17061-542: The sparsely populated Baja California Sur to the south, and similar to San Diego County, California , and Imperial County, California to its north. Over 75% of the population lives in Mexicali (the state's capital city), Ensenada , or Tijuana (the state's largest city). Other important cities include San Felipe , Rosarito , and Tecate . Baja California is the 12th-largest state by area in Mexico. Its geography ranges from beaches to forests and deserts. The backbone of

17202-548: The state include the Sierra de La Asamblea , Sierra de Calamajué, Sierra de San Luis and the Sierra de San Borja . Temperate winds from the Pacific Ocean and the cold California Current make the climate along the northwestern coast pleasant year-round. As a result of the state's location on the California Current, rains from the north barely reach the peninsula, thus leaving southern areas drier. South of

17343-471: The state is the Sierra de Baja California, where Picacho del Diablo , the highest point of the peninsula, is located. This mountain range effectively divides the weather patterns in the state. In the northwest, the weather is semi-dry and Mediterranean . In the narrow center, the weather changes to be more humid due to altitude. It is in this area where a few valleys can be found, such as the Valle de Guadalupe ,

17484-506: The state of Baja California. Jesuit missions were subsequently established among the Cochimí at Santa Gertrudis (1752), San Borja (1762), and Santa María (1767). After the expulsion of the Jesuits in 1768, the short-lived Franciscan administration (1768–1773) resulted in one new mission at San Fernando Velicatá . More importantly, the 1769 expedition to settle Alta California under Gaspar de Portolà and Junípero Serra resulted in

17625-538: The suspension of the works of channeling the Alamar stream in 2012. This request, in joint with inhabitants of the area, was a search of a more environmentally friendly and sustainable alternative. Condition failures led to the suspension of the Third Stage modification work of the concrete channelization of the Arroyo that same year. From that point onward, binational and local collaborations developed an integrated approach to governance in IMPLAN's resource management plan for

17766-477: The third highest amount of foreign direct investment of any state in Mexico, constituting about 7.7% of the national total and behind only Nuevo León (7.7%) and Mexico City (16.5%). About 81.4% of Baja California's foreign domestic investment comes from the United States , of which 50.3% comes from the construction of natural gas pipelines and 8.2% comes car and truck manufacturing. The Foreign Investment Law of 1973 allows foreigners to purchase land within

17907-486: The two ranges from December to April. Due to orographic effects, precipitation is much higher in the mountains of northern Baja California than on the western coastal plain or eastern desert plain. Pine, cedar and fir forests are found in the mountains. The east side of the mountains produces a rain shadow , creating an extremely arid environment. The Sonoran Desert region of Baja California experiences hot summers and nearly frostless mild winters. The Mexicali Valley (which

18048-469: The urban and environmental management in the Arroyo and beyond characterizes three elements: participation of citizens and organized society, coordination between three levels of government, and sectors that impact the project. The implementation of free-trade agreements within NAFTA created a new strained the intricate dynamics of environmental governance that influence the Arroyo, exerted additional pressure on

18189-512: The urban planning processes of the Arroyo has demonstrated to be a valuable contribution to the domains of environmental justice. An increase of citizen support and political will additionally promotes reconciling the socioeconomic role and relationship of the Arroyo Alamar to urban society. This is significant for creating short and long term environmental justice solutions to protect community health, enhance quality of life, upgrade urban infrastructure, and mitigate impacts from industrial processes in

18330-420: The vicinity of Mexicali. The state government has recently been considering plans to revive Laguna Salada. The highest mountain in the Sierra de los Cucapah is Cerro del Centinela or Mount Signal . The Cucapah are the primary indigenous people from the mountains north to Yuma, Arizona . There are numerous islands on the Pacific shore. Guadalupe Island is located in the extreme west of the state's boundaries and

18471-528: The west coast in 1542. Sebastián Vizcaíno again surveyed the west coast in 1602, but outside visitors during the following century were few. The Jesuits founded a permanent mission colony on the peninsula at Loreto in 1697. During the following decades, they gradually extended their sway throughout the present state of Baja California Sur. In 1751–1753, the Croatian Jesuit mission-explorer Ferdinand Konščak made overland explorations northward into

18612-462: The wooded area between the Arroyo Alamar and the Otay industrial park still work at the maquiladoras and report runoff contamination crossing the streets. Along with ecological damage, the population of this region suffers from environmental health risks and inadequate infrastructure and social services. Industrial outputs of wastewater and air smog that jeopardized the river and its watershed also prompted

18753-809: The workforce standards, such as school–enterprise linkage programs which help the development of a labor force according to the needs of the industry. 91.60% of the population from six to fourteen years of age attend elementary school. 61.95% of the population over fifteen years of age attends or has already graduated from high school. Public school is available in all levels from kindergarten to university. The state has 32 universities offering 103 professional degrees. These universities have 19 research and development centers for basic and applied investigation in advanced projects related to biotechnology, physics, oceanography, computer science, digital geothermal technology, astronomy, aerospace, electrical engineering and clean energy, among others. At this educational level, supply

18894-421: The zoning decisions. Connections between residents and IMPLAN government representatives were also established with the normative and epistemological contributions of local concerns and priorities. In such case the fusing of government-citizen relationships and knowledge exchange proved to empower community confidence, favorable land use decisions, and the protection of health and nature. Community participation in

19035-628: Was abandoned and concrete construction began in 2011. CONAGUA tendered 550 million pesos [over $ 4.1 million] to a consortium of construction companies for the concrete channelization with full consent of the Baja California governments. The choice of contractor in the deal was met with protest since the Baja-based company called Ark of the Pacific had pending lawsuits in regards to work quality and defects.  CONAGUA has also been criticized for obscuring local resident and concerns and restricting local and state influence on federal policy. Two-thirds of

19176-594: Was created, thus allowing non-Mexicans to own land without any constitutional amendment necessary. Since the law went into effect, it has undergone many modifications in order to make purchasing land in Mexico a safer investment. Newspapers of Baja California include El Centinela , El informador de Baja California , El Mexicano (edición Tijuana) , El Mexicano Segunda Edición , El Sol de Tijuana , El Vigía , Esto de las Californias , Frontera , La Crónica de Baja California , La Voz de la Frontera , and Semanario Zeta . Zoning In urban planning , zoning

19317-451: Was filled with trash. Investors and developers dumped and paid for trash load dumping since it sanctioned the land ownership claims.  The profitable business further contaminated the environment and made city-approved rehabilitation efforts more difficult. A superhighway along the channel with alleged economic opportunity and improved infrastructure is also expected to increase land value by 20-fold when developed. The Alamar Zone has been

19458-493: Was incorporated into the U.S., and during the California Gold Rush , quickly gained enough population to be admitted to the union as a state. Baja California gains control of where is now the cities of Tijuana , Mexicali , and Tecate from Alta California after the treaty and remained under Mexican control. In 1853, soldier of fortune ( mercenary ) William Walker captured La Paz , declaring himself president of

19599-786: Was practiced in many regions of the world – for example, in China during the Zhou Dynasty (1046 – 256 BC), in India during the Vedic Era (1500 – 500 BC), and in the military camps that spread throughout the Roman Empire (31 BC – 476 AD). Throughout the Age of Enlightenment and Industrial Revolution , cultural and socio-economic shifts led to the rapid increase in the enforcement and invention of urban regulations. The shifts were informed by

19740-474: Was supported in the government guidelines. The municipality of Tijuana became further alert about the Arroyo due to the recorded heavy rainfall in February 2004 . Civil protection authorities have now classified the Alamar as susceptible to flooding due to mud flow and fast avenues. Inter-institutional coordination of Civil Protection was necessary for evicting the more than 250 threatened families residing within

19881-523: Was to be conducted within a single glass-roofed building, an early concept for the modern shopping centre inspired by the Crystal Palace . However, these planned or ideal cities were static designs embodied in a single masterplan . What was lacking was a regulatory mechanism to allow the city to develop over time, setting guidelines to developers and private citizens over what could be built where. The first modern zoning systems were applied in
