UDC Section 8.7.3.C.3.b(3) allows an FLD to be developed with a density increase if the project includes preservation of a historical
, structure, or landmark or if the project leads to preservation or scientific study and documentation of a historical
, structure, or landmark. To qualify for the Maximum Density Option, an archaeological study is required to determine the potential for designation as a prehistoric or historic
or structure.
In the study, the following steps must be completed for each individual
within the project, unless determined unnecessary as outlined within this criterion. The information contained in these steps will include: the extent of such
or structures; the extent of data collection on each
; and the potential for preservation of each
, including methods or plans for such preservation. This criterion is considered satisfied upon
by the city of a report, completed by a qualified archaeologist, which provides evaluation of all steps.
The steps in an archaeological study are as follows:
Step 1. A preliminary study to determine the presence of prehistoric or historic
. This is accomplished by a thorough walk-through survey of the project
prior to any disturbance. The result of this step is an evaluation of the potential for prehistoric or historic
within the project
, according to Step 2.
Step 2. A testing of possible
identified during the preliminary and
studies. This is usually accomplished by a more detailed survey, with collection of surface artifacts; digging of test pits in possible
; or trenching to determine the depth of a
, the approximate number of features in the
, and more specific identification of the extent of the
. The result of this step is a more detailed evaluation of
potential in terms of area extent, possible age, complexity (such as multiple occupations), and number of features (such as the number of pit houses, extramural features, storage houses, or ball courts in Hohokam villages).
Step 3.

is done within the context of a scientific research design or plan and prior to destruction of the
for development. The research design or plan specifies questions to be answered by the excavating, lists methods of getting answers (including the percent of the
to be excavated), and gives special techniques to be used (such as radio carbon dating, pollen analysis, dendrochronology, etc.). The result of this step is a report on the
, an analysis of the material collected, and a synthesis of results into scientific literature or prehistoric reconstruction.
If a
or structure is identified by the archaeological study as being of significant magnitude and meeting the eligibility criteria for the National Register of Historic Places, it is to be preserved. Preservation may be pursued in a number of ways, such as, but not limited to: incorporation into the project design as common area; dedication as a conservation easement to the appropriate governmental or nonprofit agency; offer of sale, at appraised value, to the appropriate governmental agency; or dedication at nominal cost to the appropriate governmental agency. Such dedicated property may be used to calculate densities.
