Planning Policy Guidance 16: Archaeology and Planning commonly abbreviated as PPG 16, was a document produced by the UK Government to advise local planning authorities in England and Wales on the treatment of archaeology within the planning process. It was introduced in November 1990 following public outcry after a number of high-profile scandals such as the threatened destruction of the Rose Theatre in London by developers. It replaced the earlier Circular 8/87 which was criticized for being ill-focused in both practical and geographical terms. On 23 March 2010 the Government published 'Planning Policy Statement 5:Planning and the Historic Environment' [1] replacing and cancelling PPG16 and PPG15 which had dealt with the rest of the historic environment.
The document advised that archaeological remains are a finite and irreplaceable resource and that their presence should be a material consideration in applications for new development. It accepted that development will affect archaeological deposits and that this effect must be mitigated. PPG 16 stressed the importance of the evaluation of a site for its archaeological potential in advance of development in order to inform future management decisions. This evaluation may involve non intrusive methods such as a desk-based study or archaeological geophysics and/or a more direct method such as trial trenching.
Following the results of the initial evaluation, PPG 16 offered two solutions for preserving any significant archaeological deposits found to be on a development site. The first, and explicitly preferred, method involves preservation in situ whereby the archaeology is left untouched beneath a new development through methods such as adaptation of foundation design and architectural layout of the proposed new development, or by raising the level of the development with made ground so that its foundations do not reach the archaeological horizon. Where nationally important remains are encountered this method of preservation is strongly preferred.
If preservation in situ is not feasible then PPG 16 permitted preservation by record. This method involves archaeological fieldwork to excavate and record finds and features (thereby destroying them). This may involve a full excavation, further trenching in specific areas or an archaeological watching brief which involves an archaeologist monitoring groundworks for the new development and recording any finds or features revealed as construction continue.
All forms of archaeological investigation undertaken through PPG 16 are funded by the developer through an extension of the Polluter Pays principle, although this is not made explicit in the document itself. The work is intended to be undertaken in advance of any planning consent being granted but often happens to satisfy a planning condition placed on an application for development, that is once the principle of development on the land has already been established.
Because of the potential for destruction of significant remains, PPG 16 prefers evaluation to take place in advance of any planning decision being made. A developer tenders for the work to be done and chooses an archaeological organization to retain. The work is monitored by a curator, normally the County Archaeologist, who is nominated by the local planning authority as an adviser and who also identifies sites where archaeology might be threatened by development. Following submission of a satisfactory site report and demonstration that a site's archaeological potential has been properly safeguarded and/or recorded, the curator will usually advise that development can continue.
Curators maintain a Historic Environment Record or HER, a database of known archaeological sites which is often used to inform decisions on archaeological potential. Areas of archaeological potential are often drawn on GIS maps which can indicate any potentially damaging development automatically.
PPG 16 has resulted in an explosion in archaeological fieldwork in the UK. Developer funding has led to dozens of archaeological organizations competing for work along with archaeological consultants working for developers to oversee projects. This has contributed to the growing professionalization of archaeology from its more ad hoc earlier incarnation as Rescue archaeology. Also, a wider variety of archaeological methods are now employed including surveys of large areas for the purposes of Historic Landscape Characterisation, deposit models and the production of regional archaeological research agendas.
Critics of PPG 16 argue that the commercialization of UK archaeology has resulted in more work of lower quality being undertaken, and that a shortage of county archaeologists to monitor this work allows consultants to exploit the situation. In recent years prices have been driven down by competing consultants who have unethical arrangements with archaeological contractors, who rather than performing the same job for a lower cost (as in true competitive tendering) are able to do a worse job. The increased volume of work has led to a backlog of unpublished site reports and homeless site archives awaiting resolution. The competition for work amongst archaeologists, and the fact that the developers funding them see no real use for their final product, also tends to drive prices down meaning that wages and conditions for archaeologists in the UK are generally far below the national average for equivalent professions with comparable levels of education. The irony is that the cost of this unworthy body of work, known as "grey archaeology", borne by the construction industry benefits nobody but the consultants who have something to "mitigate" on behalf of their clients in the construction industry.
PPG 16 was only guidance to planners and did not have the full force of law. Its precepts could only be enforced through the Town and Country Planning Act and ultimate decisions on its implementation rested with the Secretary of State. However, without full legal status it lacked the power and reach of measures safeguarding similar environmental issues which are enshrined in law, such as those concerning endangered species.
Theoretically, the philosophical approach of PPG 16 was strongly based on processualism, especially following the publication of the de facto guidance manual for UK developer-led archaeology, English Heritage's Management of Archaeological Projects (1991), popularly known as MAP 2. This stressed the importance of evaluation, documentation and decision-making at each stage of a project based on empirical evidence and valid hypotheses. From 2006 MAP2 was replaced by a more generic project management approach for the sector "Management of Research Projects in the Historic Environment" (MoRPHE) with a specific guidance "Project Planning Note 3" (MoRPHE PPN3) covering archaeological excavation. MoRPHE PPN3 retained the staged approach, with evaluation as a quality assessment technique that was applicable at any stage during an investigation.
A similar, though less stringent, guideline to PPG 16 exists for historic buildings and the wider historic environment called PPG 15. As of 2004 both documents are proposed to be combined into a single piece of guidance called a Planning Policy Statement.
In the broadest sense, cultural resource management (CRM) is the vocation and practice of managing heritage assets, and other cultural resources such as contemporary art. It incorporates Cultural Heritage Management which is concerned with traditional and historic culture. It also delves into the material culture of archaeology. Cultural resource management encompasses current culture, including progressive and innovative culture, such as urban culture, rather than simply preserving and presenting traditional forms of culture.
Rescue archaeology, sometimes called commercial archaeology, preventive archaeology, salvage archaeology, contract archaeology, developer-funded archaeology or compliance archaeology, is state-sanctioned, archaeological survey and excavation carried out in advance of construction or other land development. Other causes for salvage digs can be looting and illegal construction. One effect of rescue archaeology is that it diverts resources and impacts pre-planned archaeological work.
Each county or unitary authority in the United Kingdom maintains a sites and monuments record or SMR, consisting of a list of known archaeological sites. Many SMRs are now developing into much broader historic environment records (HERs), including information on historic buildings and designed landscapes. Each record lists the location, type and period of site, along with a brief description and information on the location of more detailed sources of information such as site reports. This information is most commonly used to help inform decisions on the likelihood of new development affecting archaeological deposits. Government guidance requires local authorities to consider archaeology a material consideration in determining planning applications and the SMR aids this consideration.
Trial trenching is a rapid and relatively inexpensive method of archaeological evaluation used to estimate the archaeological potential of a site.
In British archaeology a watching brief is a method of preserving archaeological remains by record in the face of development threat. An archaeologist is employed by the developer to monitor the excavation of foundation and service trenches, landscaping and any other intrusive work the developer undertakes to give the archaeologist sufficient time to identify and record any archaeological finds and features; however, the arrangement is rarely satisfactory for either party.
The National Historic Preservation Act is legislation intended to preserve historic and archaeological sites in the United States of America. The act created the National Register of Historic Places, the list of National Historic Landmarks, and the State Historic Preservation Offices.
In archaeology, survey or field survey is a type of field research by which archaeologists search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area. Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) intrusive or non-intrusive, depending on the needs of the survey team and; (b) extensive or intensive, depending on the types of research questions being asked of the landscape in question. Surveys can be a practical way to decide whether or not to carry out an excavation, but may also be ends in themselves, as they produce important information about past human activities in a regional context.
Archaeological ethics refers to the moral issues raised through the study of the material past. It is a branch of the philosophy of archaeology. This article will touch on human remains, the preservation and laws protecting remains and cultural items, issues around the globe, as well as preservation and ethnoarchaeology.
Cultural heritage management (CHM) is the vocation and practice of managing cultural heritage. It is a branch of cultural resources management (CRM), although it also draws on the practices of cultural conservation, restoration, museology, archaeology, history and architecture. While the term cultural heritage is generally used in Europe, in the USA the term cultural resources is in more general use specifically referring to cultural heritage resources.
In the United Kingdom, Planning Policy Guidance Notes (PPG) were statements of the Government's national policy and principles towards certain aspects of the town planning framework.
The Valletta Treaty (formally the European Convention on the Protection of the Archaeological Heritage (Revised), also known as the Malta Convention) is a multilateral treaty of the Council of Europe. The 1992 treaty aims to protect the European archaeological heritage "as a source of European collective memory and as an instrument for historical and scientific study". All remains and objects and any other traces of humankind from past times are considered to be elements of the archaeological heritage. The archaeological heritage shall include structures, constructions, groups of buildings, developed sites, moveable objects, monuments of other kinds as well as their context, whether situated on land or under water." (Art. 1)
Historic England is an executive non-departmental public body of the British Government sponsored by the Department for Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic parks and gardens and by advising central and local government.
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology, history or geography.
The Glamorgan-Gwent Archaeological Trust is an Archaeological Trust organisation established in 1975 as part of the Welsh Archaeological Trusts.
The Department of Archaeology and Historic Preservation (DAHP) is an independent government agency in Washington state which serves several functions, including regulatory functions. The agency inventories and regulates archaeological sites; houses Washington's State Historic Preservation Officer, State Archaeologist, State Architectural Historian and State Physical Anthropologist; maintains the Washington Heritage Register and Heritage Barn Register; provides expertise on environmental impacts to cultural resources; administers historic preservation grants for heritage barns and historic county courthouses; encourages historic preservation through local governments; provides technical assistance for historic rehabilitation and using historic preservation tax credits; and maintains extensive GIS databases to catalog the state's historic and prehistoric cultural resources.
The Underwater Archaeology Branch (UAB) of the Naval History & Heritage Command (NHHC) is a unit of the United States Department of the Navy. It was formally founded in 1996 as a consequence of the emerging need to manage, study, conserve, and curate the U.S. Navy's submerged cultural resources.
Registered battlefields in the UK are battlefields recognised as having specific historic or cultural significance. They are recognised as such by conservationist organisations for a variety of reasons, including protecting them from development that may threaten historic buildings, items, or topography. The history relating to them is often hard to unravel, as there is often little to see above ground and the historical record is often biased in favour of the victors. The UK has many historic battlefield sites, some of which have legal protection through heritage protection legislation whilst others are protected through landscape legislation. More recently, some archaeologists prefer the term "site of conflict" to "battlefield", because of the difficulty in defining the geographical extent of a site.
Archaeology and conservation of cultural resources in Ontario fall under the Ministry of Tourism, Culture and Sport. The Province of Ontario has created Acts to insure the protection archaeological and cultural resources. Acts such as the Ontario Heritage Act and Environmental Assessment Act provide the major legal documents that protect heritage and cultural resources. Additionally, Acts such as the Planning Act, the Aggregate Resource Act and the Ontario Cemeteries Act are also implemented when specific triggers occur during archaeological assessments.
The National Planning Policy Framework (NPPF) is a land-use planning policy in England. It was originally published by the UK's Department of Communities and Local Government in March 2012, consolidating over two dozen previously issued documents called Planning Policy Statements (PPS) and Planning Policy Guidance Notes (PPG) for use in England. It has since been revised in 2018, 2019 and 2021.
The conservation and restoration of archaeological sites is the collaborative effort between archaeologists, conservators, and visitors to preserve an archaeological site, and if deemed appropriate, to restore it to its previous state. Considerations about aesthetic, historic, scientific, religious, symbolic, educational, economic, and ecological values all need to be assessed prior to deciding the methods of conservation or needs for restoration. The process of archaeology is essentially destructive, as excavation permanently changes the nature and context of the site and the associated information. Therefore, archaeologists and conservators have an ethical responsibility to care for and conserve the sites they put at risk.
