<br />lllld llcadl~rl1ic COll1rnlll\ilil'~ wdl be-
<br />available to-assist in defining contexts
<br />and in identif,y'ing sources of
<br />information. In other cases, however,
<br />development of historic contexts may
<br />occur in areas whose history or
<br />prehistory has not been extensively
<br />studied. In these situations, broad
<br />general historic contexts should be
<br />initially identified using available
<br />literature and expertise. with the
<br />expectation that the contexts will be
<br />revised and subdivided in the future as
<br />primary source research and field
<br />survey are conducted. It is also
<br />important to identify such sources of
<br />information as existing planning da la,
<br />which is needed to establish goals for
<br />identification, evaluation, and
<br />treatment. and to identify factors that
<br />will affect attainment of those goals.
<br />The same approach for obtaining
<br />information is not necessarily desirable
<br />for aU historic contexts. Information
<br />should not be gathered without first
<br />cons\dering its relative importance to
<br />the historic context. the cost and time
<br />invo'lved, and the expertise required to
<br />(,ht.lin it. In many c<J~cs. for example.
<br />published sources may be used in
<br />writing initial definitions of historic
<br />contexts; archival research or field work
<br />may be needed for subsequent activities.
<br />b. Assessing information: All
<br />information should be reviewed to
<br />identify bias in historic perspective,
<br />methodological approach, or area of
<br />coverage, For exampl~, field surveys for
<br />archeological sites may have ignored
<br />historic archelolgical sites, or county
<br />land use plans may have emphasized
<br />only development goals,
<br />
<br />3. Synthesize information
<br />
<br />The information collection and
<br />analysis results in a written narrative of
<br />the historic context. This narrative
<br />provides a detailed synthesis of the data
<br />that have been collected and analyzed.
<br />The narrative covers the history of the
<br />atea from the chosen perspective and
<br />identifies important patterns, events,
<br />persons or culfurnl values. In the
<br />process of identifying the important
<br />patterns, one should consider:
<br /><l. Trends in areA settlement and
<br />uevelopment, if relevant:
<br />b. Aesthetic and nrtistic valtlc~
<br />embodied in architecture. construction
<br />technology or craftsmanship:
<br />c. Research values or problems
<br />relevant to the historic context; social
<br />Rnd physical sciences and humanities:
<br />Bnd cultural interests of loc.al
<br />communities; and
<br />
<br />d. Intangible cultur.d values of ethnl~
<br />groups and native American peoples.
<br />
<br />4. Dt'fin/.' I'mpl'rfy tYliI's
<br />
<br />A projJl~rty type is Ii grouping of
<br />individual properties bused un shared
<br />physical or associative characteristics,
<br />Property types link the ideas
<br />incorporated in the theoretical historic
<br />context with actual historic pruperties
<br />that illustrate those ideas. Property
<br />types defined for each historic context
<br />should be directly related to the
<br />conceptual basis of the historic context.
<br />Property Iypes defined for the hi~toric
<br />context "Coal r-.lining in Northeastern
<br />Pennsylvania. 1860--1930" might include
<br />coal extraction and processing
<br />.complexes: railroad and canal
<br />transportation systems: ccmmercial
<br />districts; mine workers' housing;
<br />churches, social clubs and other
<br />community facilities reflecting the ethnic
<br />origins of workers: and residenct~s and
<br />other properties associated with mine
<br />owners and other industrialists.
<br />a. IdentIfy property types: The
<br />narrative should discuss the kinds of
<br />properties expected within the
<br />geographical limits of the context and
<br />group them into those properly types
<br />most llseful in rcpresCllting important
<br />historic trends.
<br />Generally. property types should be
<br />deEned after the historic context has
<br />been defIned, Property types in common
<br />usage ("Queen Anne houses," "mill
<br />buildings," or "stratified sites") should
<br />110t be adopted without firsl verifying
<br />their relevance to the historic contexts
<br />bein::l used.
<br />b. Characterize the ]o(:(Jlionof
<br />patterns of property types:
<br />Generalizations about where particular
<br />types of properties are likely to be found
<br />can serve as a guide for identification
<br />and treatment. Generalizations about
<br />the distribution of archeological
<br />propert.ies are frequently used. The
<br />distribution of other historic properties
<br />often can be estimated based on
<br />recognizable historical. environmental
<br />or culturul factors that determined their
<br />location, Locational patterns of property
<br />types should be based upon models that
<br />have on explicit theoretical or historical
<br />basis and cilh be tested in the field. The
<br />model may be the product of historical
<br />research and analY:Jis ("Prior to
<br />widespread use of stearn puwn. mills
<br />were located un rivers and streams uole
<br />to produce water power" or "plantiltion
<br />houses in the Mississippi nJack Delt
<br />were located on sandy clay knulls"). or
<br />it may result from sampling techniques.
<br />Often the results of statistically valid
<br />sample surveys can be used to describe
<br />the locationai patterns of a
<br />repre!lentative portion of prope~tie8
<br />
<br />44719
<br />
<br />belonging to a particular property type.
<br />Other surveys can also provide a basis
<br />for .';lJgRe~.lin1<': loeational piltlCrtl:l: if a
<br />div(:r;iity of histuric propertie:J was
<br />recorded and n variety of environmental
<br />zone:') was inspected, It i~ likely that the
<br />identification of lacational patterns will
<br />come from a combination of these
<br />sources. Expected or predicted
<br />IDeational pallerns of property types.
<br />should be developed with a provisiun
<br />maue for their verification.
<br />c. Churocferize the current condition
<br />of property types: The expected
<br />condition of property types should be
<br />evaluated to assist in the development
<br />of identification, evaluation and
<br />treatment strategies, and to help define
<br />physical integrity thresholds for various
<br />property types, The following should be
<br />assessed for each proIJf:~rty type:
<br />(1) Inherent characteristics of a
<br />property type that either contribute to or
<br />detract from its physical preservation,
<br />For example. a property type commonly
<br />constructed of fragile materials is more
<br />likely to be deteriorated than 8 property
<br />type constructed of durable materials-;
<br />structures whose historic function or
<br />design limits the potential for alterna.tive
<br />uses (water towers} are less likely to be
<br />reused than structures whose design
<br />allows a wider variety of other uses
<br />(commercial buildings or warehouses).
<br />(2J Aspects of the social and natural
<br />environment that may affect the
<br />preservation or visibility of the property
<br />lype. Fur example, cornrnunily values
<br />placed on certain types of properties
<br />(churches. historic cemeteries) may
<br />result in their maintenance while the
<br />need to reuse valuable materials may
<br />stimulate the disappearance of
<br />properties like abandoned houses and
<br />barns,
<br />H may be most efficient to estimate of
<br />the condition of property types based on
<br />professional knowledge of existing
<br />properties and field test the'le estimates
<br />using a small sample of properties
<br />representative of each type,
<br />
<br />5. IdentIfy information needs
<br />
<br />Filling gaps in information is an
<br />important element of the preservation
<br />plnn designed for each historic context.
<br />Statements of the information needed
<br />should be as specific as possible,
<br />focusin;.: on lhe information need(~d. the
<br />historic context lJnd property types it
<br />upplies to, ilml why the information is
<br />needed to perform identification, .
<br />evaluation, or treatment activities.
