Steven Land Tillotson has been an advocate for sustainable and context-sensitive development and community revitalization in San Antonio and South Texas for over 3 decades.
On May 7, 2014, Tillotson presented Mapping the Cultural Landscape of San Antonio at Metro Health's Public Health & the Built Environment: Healthy Communities By Design conference.
ICT role in 21st century education and it's challenges.
Mapping the Cultural Landscape of San Antonio
1. Mapping the Cultural Landscape of San Antonio
The study of the process whereby an antecedent rural landscape translates
itself into urban form has hardly begun. And yet pre-urban land division may
well be the most fundamental determinant for the irregular city-forms of all
ages. The main problem is that it is very hard, when not actually impossible, to
reconstruct this initial landscape either through field work or documents.
Spiro Kostoff, The City Shaped
2. Cultural Landscape
What is it, and why should it be considered?
A cultural landscape is the result of the human imprint
on the natural realm, the natural landscape fashioned
by the hand of man.
The term originates from anthropological studies to
more fully understand and explain the contextual
relationships in social studies.

for architects?

Measure is intrinsic to the design, habitation, and representation of
land. It underlies the variety of ways land is traversed and
negotiated; it enables the spacing, marking, delineation, and
occupation of a given terrain; and it reflects the values and
judgments of the society that lives upon the land…Measure, then, is
as much a conceptual apparatus as it is a mode of representation,
facilitating events while constructing a particular world.

26. The Laws of the Indies regulated social,
political and economic life in the
American and Philippine Spanish
Colonies and provided the planning
precepts for the formation of
settlements and towns..
The laws were compiled several times,
most notably in 1680 under Charles II
in the Recopilación de las Leyes de los
Reynos de Indias (Compilation of the
Laws of the Kingdoms of the Indies).
The laws emphasized respect for native
populations.
LAWS OF THE INDIES

28. “…choose the province, county, and place which will be settled
taking into consideration the health of the area which will be
known from the abundance of old men or of young men of
good complexion, natural fitness and colour, and without
illness; and in the abundance of healthy animals of sufficient
size, and of healthy fruits and fields where no toxic or noxious
things are grown, but that it be of good climate, the sky clear
and benign, the air pure and soft, without impediment or
alterations and of good temperature, without excessive heat or
cold…and they should be in fertile areas with an abundance of
fruits and fields, of good land to plant and harvest, of
grasslands to grow livestock, of mountains and forests for
wood and building materials for homes and edifices, and of
good and plentiful water supply for drinking and irrigation.”

San Antonio’s
urban fabric is a

patterns that
overlay the natural
divide between hill
country and
prairie, resulting in
an episodic and
polymorphic city
form.

101. Laws of the Indies
Classical/Geomorphic Grid
17th century planning
precepts for Spanish
Colonial towns promoted a
uniform street grid with a
central plaza. This ideal
form is well adapted to the
course alignment of the
San Antonio River and San
Pedro Creek.
Spanish Land Grant
Metes & Bounds - Geomorphi
Boundaries establishing the
1733 Land Grant also
connected strategic point of
defense and access:
hilltops along the northern
boundaries and water
crossings along the
southern boundaries.
Aransas, Ogden, Jackson
Keller, Hillcrest, Acme and
Nogalitos mark the limits of
Villa San Fernando.
Terrain
Topography/Drainage
Open gravity flow irrigation
channels for agricultural and
domestic water were in use
for more than half of San
Antonio’s history. Their
courses became geometric
determinants in subsequent
urbanization. SAN ANTONIO CULTURAL LANDSCAPE
Acequia
Geomorphic –
Linear/Orthogonal
The geomorphographic
character is determined by
the geology, soils, flora,
climate, and resultant land
form.
102. Secularization of missions
Concepcion, San Jose, San
Juan and Espada resulted in
land grants with narrow
frontage on the San Antonio
River and extremely long side
boundaries oriented east/west.
Payments of land by the Republic
of Texas for military service
encouraged settlement north of
the 1733 Spanish Land Grant.
The parcel configuration is
aligned with the NE and NW
boundaries of the 1733 grant.

Township
Streets that follow the 1852
subdivision of the propios for
public auction. The majority
of the streets are oriented
true north; the west side grid
streets are slightly east of
north due to initial alignment
with San Pedro Creek.
Many Spanish Colonial
regional roads followed the
preexisting indigenous trail
network between strategic
destinations. The
convergence of these roads
emerged as radials
imbedded in the expanding
city.SAN ANTONIO CULTURAL LANDSCAPE

103. Drainage
Geomorphic Stream Bed
Hillside
Geomorphic
Closely related to Riparian
Streets, Hillside Streets are
associated more with steeper
grades remote from
significant streambeds.
Primary streets are parallel
with contours to provide
terracing and secondary
streets orthogonally traverse
the slope.
Railroad
Radial Pattern
Rail lines generally follow the
earlier Caminos Reales and
so approach the center in
radial pattern until squaring
up with the cardinal
alignment of downtown
streets.
Drainage pattern streets
are physiographically
similar to acequia pattern
streets as they are
designed to convey water,
but drainage streets are for
the confluence of runoff
rather than distribution of
irrigation, and a low-cost
stormwater solution for 20th
century subdivisions.
Expressway
Radial/Concentric Pattern
The primary State and US
Interstate highways are larger
scale successors to the
Caminos Reales and so are
radial in pattern at the regional
scale. Similar to most other
cities San Antonio has
circumferential loops for moving
and distributing large volumes
of traffic.
