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.
UDC Section 8.7.3.C.3.b(8) allows an FLD to use the Maximum Density Option if the project is designed and located to comply with the requirements listed below. The requirements are grouped into three categories:
, siting, and design. These three categories list a total of 31 criteria. Projects meeting a minimum of 20 criteria of the 31 comply with the requirements of this provision.
The Green Building Maximum Density Option requirements may not be modified through the Technical Standard Modification Request process. A request to deviate or waive a Green Building Maximum Density Option requirement must be submitted to the Board of Adjustment for

A. The project boundary is within one-fourth mile of an existing bus line.
B. The project is located in a low water-lift zone (below an elevation of 2,700 feet).
C. The project qualifies as urban infill, e.g., there is an existing R-1 subdivision or more intense development within one-fourth mile of the project boundaries on all sides.
D. The project is located within 1,000 feet of existing water, electric, and natural gas distribution lines of sufficient capacity to serve the project.
E. The project is a mixed commercial and residential use, either designed as a consolidated project or by its relation to adjacent commercial projects.
F. The project is located within one mile of the University of Arizona or the Downtown District.
G. The project is located within 2,000 feet of:
1. An existing neighborhood shopping center;
2. Property for which a final or conditional ordinance has been adopted rezoning the property for such use; or,
3. Property for which a building permit has been issued, and is still current, for the construction of such use.
H. The project is located within 4,000 feet of:
1. An existing regional shopping center;
2. Property for which a final or conditional ordinance has been adopted rezoning the property for such use; or,
3. Property for which a building permit has been issued, and is still current, for the construction of such use.
I. The project is located within 3,500 feet of an existing or reserved neighborhood park, regional park, or other public recreational or community facility.
J. The project is located within 1,000 feet of a school which meets all the requirements of the compulsory education laws of the State of Arizona.
K. The project boundary is 30% or more contiguous to an existing R-1 subdivision or more intense development.
L. The project is located within 3,000 feet of a major employment center.
M. The project is located within one-half mile of a public bikeway,
, or bike path and incorporates pathways which connects to these.
A. Buildings are designed with windows oriented to provide at least five hours of solar access on December 21 between the hours of 9:00 a.m. and 4:00 p.m.
B. Buildings are designed to provide complete shade to all windows on June 21. On new construction,
devices which require manual operation to accomplish the
do not qualify as building design that provides shade.
C. Building design and deciduous landscaping at maturity are integrated into the project to provide shade to 80% of the east and west facing walls on June 21. On new construction, landscaping alone does not satisfy this criterion.
D. Paved areas, such as sidewalks and parking areas, are shaded with deciduous shade trees or architectural
elements, such as trellises, roofs, etc. Principal sidewalks are those which provide access from parking to each unit and from each unit to all common areas. Shade trees in a parking area are to be within a protected landscaped area with a minimum width of five feet and at a ratio of two trees for every 3,000 square feet of parking area.
E. Eighty percent of all buildings are located and constructed to provide at least five hours of solar access to three-fourths the height of the south wall on December 21. This requirement must take into account walls and vegetation which could block solar access.
F. Eighty percent of the buildings within the project are positioned with the longer axis, if any, oriented within 22 degrees of a true east/west direction.
A. At least 80% of the dwelling units are constructed with common walls.
B. All buildings are earth sheltered, partially protected by earth berms, or built into an existing hillside or
.
C. All buildings are constructed with insulation at foundations and floor slabs at
.
D. All building envelopes have an overall average thermal resistance value (R value) of 24 or greater.
E. Buildings have windows that can be opened and which are oriented between 20 and 70 degrees of prevailing diurnal wind patterns to provide natural through ventilation. The windows are to be double glazed and spaced at least three feet apart.
F. Individual units feature a minimum area of glass, to be less than 10% of the exterior wall area.
G. At least 80% of the residential buildings do not have windows on the east facade.
H. At least 80% of the residential buildings do not have windows on the west facade.
I. The residential buildings include overhangs on the south facade to provide

K. At least 80% of the dwelling units are designed to provide a private unroofed outdoor space for sleeping, such as a rooftop deck or sun porch.
L. At least 80% of all buildings are constructed with light-colored roofs and walls.
