Introduction
SAN JACINTO HISTORIC DISTRICT<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> is an area with a rich history closely identifi ed with <strong>Texas</strong> independence<br />
and prosperity. The world’s tallest war memorial is located at the site of the Battle of <strong>San</strong> <strong>Jacinto</strong>, the pivotal<br />
event that concluded the <strong>Texas</strong> Revolution. The <strong>District</strong> includes the 25 mile Houston Ship Channel, is one of<br />
the world’s most infl uential energy corridors and trade ports. The Economic Alliance Houston Port Region,<br />
a non-profi t organization created in 1985, provides professional economic development services to the 16<br />
communities and other agencies in the <strong>District</strong>.<br />
The 280,000 acre <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> encompasses sixteen<br />
port region communities, the Port of Houston, and Harris County. The<br />
region is ranked fi rst in the United States in foreign waterborne tonnage<br />
and second in total tonnage and includes the third largest county in<br />
the United States, the country’s largest refi ning and petrochemical<br />
manufacturing industry, Barbours Cut and Bayport Cruise Terminals, the<br />
2,500 acre Armand Bayou Nature Center wildlife refuge and preserve, and<br />
the birth place of the State of <strong>Texas</strong>.<br />
The Economic Alliance has spearheaded an eff ort to identify the <strong>District</strong><br />
with a unifi ed character and theme that recognizes and highlights the<br />
history of the area, the vibrancy of the communities, and the region’s strong<br />
economic base. This eff ort has led to a number of initiatives, including<br />
Project Stars, a vision to use the industrial infrastructure and landscape<br />
of the <strong>District</strong> to celebrate and display these att ributes in interesting and<br />
exciting ways, such as EPICArt depictions of scenes from local historic<br />
events as massive outdoor murals.<br />
EPICArt on tank.<br />

The on-going implementation of the master plan for Project Stars will<br />
transform the region into one of the world’s most truly unique places, an<br />
area that marks its rich historical past while embracing the present and<br />
future. The goal of the plan is to celebrate the local heritage by identifying<br />
over 26 sites that shaped <strong>Texas</strong> History in a way that brings pride and<br />
beauty to the area.<br />
To further support the goals of the <strong>District</strong> and the Project Stars Initiative,<br />
the Economic Alliance has also sponsored and directed the development<br />
of this comprehensive set of corridor themes and site improvement<br />
standards, which are intended to complement and be used in conjunction<br />
with the Project Stars sites.<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Corridor Standards is a project of<br />
the Economic Alliance Houston Port Region’s Quality of Life Task Force,<br />
whose regional survey listed standards and beautifi cation as a primary<br />
goal for the <strong>District</strong>. The project Technial Advisory Committ ee and the<br />
eighteen project stakeholders guided the project through a year long<br />
process, which included a number of meetings and open houses to review<br />
the ideas presented and solicit input. These standards are intended to<br />
provide recommendations to maximize the value, performance, and<br />
aesthetic quality of capital and long-term operational expenditures<br />
for the public realm (primarily corridors) throughout the <strong>District</strong>. It<br />
includes example scenarios where improvements may be made, <strong>elements</strong><br />
and furnishings that evoke the history and culture of the <strong>District</strong>, and<br />
practices for <strong>design</strong> and implementation of improvements along the<br />
right-of-way. Public and private landowners are encouraged to refer to the<br />
recommendations of this document as a starting point for planning and<br />
<strong>design</strong>ing improvement projects in collaboration with relevant partners,<br />
agencies, and organizations.<br />

Project Stars locations within the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong>.
NATURAL HISTORY<br />
At the time of European settlement, the coastal province of the area between <strong>San</strong> <strong>Jacinto</strong> and the Gulf of<br />
Mexico was low, fl at, and vegetated by prairies of grasses, wildfl owers, and fl owering shrubs of indescribable<br />
beauty. The water table was at or near the surface in most places, but in some areas, where the land<br />
undulated to form low mounds, there grew groves of open-grown trees, mostly oaks, and a few pines.<br />
For the thousands of years prior to Western sett lement, this landscape was<br />
sustained as a beautiful, unique, and highly bio-diverse system through<br />
occasional grazing and regular fi res set by the native peoples. A few of<br />
the last remnants of this coastal vegetation still exist at the Armand Bayou<br />
Nature Center, in Pasadena, <strong>Texas</strong>.<br />
The water edges and estuaries along the <strong>San</strong> <strong>Jacinto</strong> and smaller drainages<br />
were treeless marshes crossed by numerous shallow, narrow, estuarine<br />
channels infl uenced by salt water tides, and fed by groundwater and 50<br />
to 60 inches of rain per year. These watery sloughs were the spawning<br />
areas of millions of fi sh that inhabited the western districts of the Gulf of<br />
Mexico. The marshes, prairies, and oak groves provided desirable home<br />
to countless birds, many of whom had wintered in the Yucatan and other<br />
subequatorial districts.<br />
The fl ora and fauna of the <strong>San</strong> <strong>Jacinto</strong> are among the more beautiful and<br />
singular of any province anywhere in the world. The extent to which the<br />
architecture, infrastructure, landscape, and other <strong>design</strong> <strong>elements</strong> support<br />
the integration of <strong>San</strong> <strong>Jacinto</strong>’s original assets and cultural history to<br />
enhance and celebrate the uniqueness of <strong>San</strong> <strong>Jacinto</strong> is the extent to which<br />
the area will be seen as unlike anywhere else on earth and truly special.<br />

CORRIDOR STANDARDS<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Corridor Standards are intended to guide the <strong>design</strong>, construction, and<br />
maintenance of all visible public landscapes within the <strong>District</strong>. This includes roadway corridors - freeways,<br />
main streets, and local roads. It also includes feature sites - community gateways, historic sites, EPICArt sites,<br />
and Project Stars locations. The Standards include <strong>elements</strong> that cities, the county, and private developers<br />
can refer to when planning new development, and a list of architectural, lighting, and landscaping themes<br />
that refl ect the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong>.<br />
The Corridor Standards were developed with a process specifi cally<br />
structured to tailor nationally-recognized, leading edge landscape and site<br />
development practices to local conditions, character, and qualities unique<br />
to the <strong>District</strong>. This process began with the identifi cation of stakeholders<br />
- representatives of the diverse backgrounds and interests of the people<br />
served by the public realm in the <strong>District</strong>. Workshop meetings, a narrated<br />
bus tour of prominent cultural and historic sites, listening sessions, and<br />
two open houses provided a two-way dialogue to help understand the<br />
context and priorities for the Standards, and to describe the potential<br />
long-term value created through the integration of restorative, sustainable<br />
materials and practices.<br />
Early in the process, a set of guiding First Principles were articulated,<br />
which identify the qualities and values of the <strong>District</strong> that the Standards<br />
are meant to support. Then, a draft set of guidelines were identifi ed,<br />
prioritized, and refi ned. Following review and discussion, a fi nal set of<br />
standards were described and illustrated. The diversity of the sixteen<br />
communities and other agencies in the <strong>District</strong> requires these corridor<br />
standards to provide an illustrative vision yet also create the opportunity<br />
for those entities to individualize community character.<br />
10 │ INTRODUCTION<br />
This document includes three primary components that, in combination,<br />
provide guidance to achieve the <strong>District</strong> goals.<br />
Design Scenarios<br />
A set of Design Scenarios intended to help illustrate the application of the<br />
standards in typical situations and contexts.<br />
Design Elements<br />
Design Elements refer to materials, pavements, plantings, furnishings,<br />

Sustainable, ecologically-based<br />
Landscapes and infrastructure within the corridor are developed<br />
using integrated green practices that support the health and vitality<br />
of the area.<br />
Cost effective, long-term value<br />
Design <strong>elements</strong> will provide economic value through the integration<br />
of sustainable practices and the analysis of both capital costs and longterm<br />
operations/maintenance costs.<br />
Enhanced image through integrated systems<br />
and creative applications of public art<br />
The perception and image of the area will draw interest, visitors, and<br />
investment through the creative integration of sustainable practices<br />
with public art that is beautiful, functional, and educational.<br />
Beautiful<br />
Public improvements and amenities that are made to be beautiful will<br />
be loved by the community, embraced, and sustained over time.<br />
Engaging, educational<br />
Public improvements and displays that provide lessons about the past,<br />
and demonstrations for the future, will engage people and generate<br />
interest in the area.<br />

Partnerships<br />
Collaboration and partnership with all of the key stakeholder groups<br />
and organizations in the area will ensure successful implementation<br />
of the standards.<br />
Authentic - true to the unique cultural<br />
and natural history of the <strong>District</strong><br />
Installations done with att ention to accuracy and authenticity will<br />
honor the past and carry the legacy forward to future generations.<br />
Sense of place and local pride - locally<br />
sourced, local craftsmen / artisans<br />
Pride and connection to the area through public amenities and<br />
infrastructure built with local materials and craftsmen, which helps<br />
support a vibrant local economy.<br />
Connections, multi-modal accessibility<br />
Public infrastructure that supports safe, convenient pedestrian and<br />
bicycle access will att ract greater investment and visitors, and will<br />
best serve the long-term interests of the community.<br />
10. Compatible with existing codes, guidelines, and policies<br />
Designs will be compatible with existing regulatory policies to the<br />
degree possible to ensure they are embraced by the municipalities<br />
and agencies within the <strong>District</strong>.<br />

HOW TO USE THIS GUIDE<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Corridor Standards are structured to be a tool to assist in the <strong>design</strong>,<br />
construction, and maintenance of culturally relevant, sustainable, and restorative landscapes, public<br />
amenities and furnishings, and other features throughout the <strong>District</strong>. This standards document includes a<br />
succinct set of <strong>design</strong> <strong>elements</strong> and best practices that cover planting/vegetation, pavement, lighting,<br />
and site amenities. Public and private landowners can turn to these standards to select specifi c vegetation<br />
and furnishings that will help maintain a consistent ‘look and feel’ throughout the <strong>Historic</strong> <strong>District</strong>, or they can<br />
use the standards to get a general idea of the desired character and identify similar <strong>design</strong> <strong>elements</strong>.<br />
The Corridor Standards are articulated in the three components of the<br />
document mentioned in the overview: Design Scenarios, Design Elements,<br />
and Best Practices. A user of this document can look at the Scenarios to see<br />
an example of the application of these standards in a similar context. For<br />
example, if one is <strong>design</strong>ing a community main street enhancement, they<br />
can look at the Main Streets scenario for an idea of how Design Elements<br />
can be integrated into a Main Street <strong>design</strong> concept. The user can look to<br />
the Design Elements to see the list of proposed materials and <strong>elements</strong>,<br />
and choose those that are relevant for that particular project. The user can<br />
also refer to the Best Practices for a particular element to bett er understand<br />
how to best integrate the <strong>elements</strong>, and what benefi ts they off er.<br />
Once a particular project has been conceived, the <strong>design</strong> process includes<br />
a number of steps that generally include site assessment, programming,<br />
conceptual <strong>design</strong>, budgeting, detailed <strong>design</strong> and engineering, bidding,<br />
construction, and post-construction maintenance. In order to achieve<br />
the qualities, performance, and value envisioned by these standards, the<br />
<strong>design</strong> process should include the following.<br />

Committed Sponsorship<br />
The leadership behind the project must understand and embrace the<br />
value and benefi t off ered by these standards and commit to <strong>elements</strong><br />
needed to achieve them.<br />
Collaborative Team of Professionals<br />
Landscape architects, architects, engineers, transportation planners,<br />
horticulturists, ecologists, energy specialists, artisans, and other<br />
professional disciplines must be enlisted to collaborate with each<br />
other and the project leadership to evolve the <strong>design</strong> and integrate the<br />
various <strong>elements</strong> and opportunities presented by the project.<br />
Open, Interactive Design Process<br />
In order for the project to be well-received, loved, and cared for over<br />
time, it must meet the needs of the people it will serve. Inclusion of<br />
these stakeholders is essential. Identifying potential stakeholders<br />
and including them early in the <strong>design</strong> process greatly benefi ts the<br />
process and the outcome. The Economic Alliance has been working to<br />
raise awareness of this initiative. The planning process was open and<br />
inclusive; within the <strong>District</strong>, stakeholders and the Technical Advisory<br />
Committ ee included representatives of the following:<br />
La Porte<br />
Baytown<br />
Channelview<br />
BayTran<br />
Deer Park<br />

Port of Houston Authority<br />
Design Responsive to Local Conditions<br />
A thorough analysis and assessment of existing conditions and contexts<br />
is essential to a responsive, eff ective <strong>design</strong>. The analysis should be<br />
clearly documented and articulated as the basis of the <strong>design</strong>.<br />
5.<br />
Alignment with other Requirements<br />
A number of agencies have established protocols for project<br />
development. Of greatest importance, perhaps, is TxDOT’s Project<br />
Development Process Manual, which should be followed for work<br />
occurring on land owned and managed by TxDOT. The process<br />
is divided into several sub-processes including planning and<br />
programming, preliminary <strong>design</strong>, environmental, right-of-way and<br />
utilities, PS&E (Plans, Specifi cations, and Estimates), and lett ing.<br />
Complex projects may require all of these steps, while simpler ones<br />
may only need a few. In the context of the transportation corridor,<br />
the implementation of these Corridor Standards should prioritize the<br />
safety and security of the driver, cyclist, pedestrian, and other users<br />
through the application of TxDOT’s standards and requirements.<br />
TxDOT has embraced the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> and the<br />
First Principles of the Corridor Standards, and indicated they would<br />
embrace the <strong>design</strong> guidelines for future TxDOT projects within the<br />
<strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong>.<br />
There are other <strong>design</strong> tools that should be utilized to help provide<br />
more eff ective, successful, sustainable projects. Eff orts are underway<br />
to develop a nationwide voluntary rating system for sustainable site<br />
development. Texans can be proud that one of the three main partners<br />
in this eff ort is the Lady Bird Johnson Wildfl ower Center in Austin,<br />
<strong>Texas</strong>. Others include the American Society of Landscape Architects<br />
and the U.S. Botanic Garden. The Sustainable Sites Initiative, also<br />
known as SITES (www.sustainablesites.org), establishes benchmarks<br />
for achieving sustainability within nine categories: site selection, pre<strong>design</strong><br />
assessment and planning, water, soil and vegetation, materials<br />
selection, human health and well-being, construction, operations<br />
and maintenance, and monitoring and innovation. The initiative<br />
outlines <strong>design</strong> steps that may be missing from other established<br />
protocols, such as monitoring a site after construction to evaluate its<br />
performance. Projects within the district are encouraged to participate<br />
in this initiative where practical.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 13
Implementing the Corridor Standards<br />
Making the vision of a distinct <strong>Historic</strong> <strong>District</strong> a reality requires a strategic<br />
and conscientious action plan for short and long term priorities that relies<br />
on the collaborative involvement of public and private sector entities.<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Corridor Standards should be<br />
presented to the Mayor, Councils, and governing boards of the sixteen<br />
<strong>District</strong> communities, the Houston Ship Channel and its industries,<br />
TxDOT, the Port of Houston, Armand Bayou, the Houston Galveston Area<br />
Council, Councils of Governments, and Harris County, with a request for<br />
recognition, endorsement, and adoption of the standards. They should<br />
also be posted to community websites for wide public distribution. Each<br />
community should hold a public forum to present the standards to the<br />
community and to discuss the need for public and private eff orts for<br />
implementation when improvements are being considered within the<br />
corridors, gateways, and Project Stars sites. For example, Harris County<br />
Commissioner Sylvia Garcia holds several meetings with the communities<br />
located within Precinct Two where this could be accomplished.<br />
Each of the eff orts of recognition should be coordinated with local, state,<br />
and national press coverage that is carefully orchestrated with a public<br />
involvement plan. Press packages will allow information to be shared in<br />
an effi cient and consistent way and tell the story of how communities and<br />
their constituents can be part of this history-making eff ort.<br />
A <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Summit should be held in the fall with<br />
the goal of sharing information and preparing priorities and projects for<br />
the spring budget process. The Economic Alliance Houston Port Region<br />
could assist in facilitating the meeting.<br />
14 │ INTRODUCTION<br />
Communities should consider using the extensive Harris County<br />
Geographic Information System (GIS) mapping system to help prepare<br />
and map a three to fi ve year <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Capital<br />
Improvement Plan (CIP) project list. This list can be posted annually so<br />
that private sector partners are aware of implementation activities.<br />
Implementation will require the recognition of the standards and <strong>elements</strong><br />
and inclusion of standards in Capital Improvement Plans and annual<br />
budgets. Clearly, funding will be critical to realizing the collective <strong>District</strong><br />
vision. Individual jurisdictions have an assortment of tools available to<br />
incentivize private investment and improvements to the public realm.<br />
The deployment of strategic tax abatement, tax increment fi nancing,<br />
economic development agreements, and other public-private partnership<br />
instruments can be very eff ective as catalysts for voluntary participation.<br />
As local and regional agencies review funding requests from communities<br />
in the region, they can also make sure that the Corridor Standards are<br />
recognized as a part of the review. For example, the Houston Galveston<br />
Area Council (H-GAC) is now providing funding for Livable Centers,<br />
walkability, and other related programs, which are recommended in the<br />
Corridor Standards. Since the H-GAC funding cycle is three to six years,<br />
planning in advance could prepare the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong><br />
for federal or state funding using city funds as local match.<br />
See Appendix D <strong>Texas</strong> Toolbox for additional fi scal and regulatory tools<br />
for implementation.

Design Scenarios<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 15
DESIGN SCENARIOS<br />
This chapter presents conceptual Design Scenarios appropriate for a variety of corridor conditions found<br />
throughout the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> including freeways, farm to market roads, local roads, main<br />
streets, community gateways, and Project Stars sites. The graphics are intended to illustrate the application<br />
of the Design Elements (Chapter 3) and Best Practices (Chapter 4) to typical scenarios, including their<br />
spatial arrangement and orientation.<br />
Each scenario includes an aerial photograph and brief description of<br />
the existing site condition, contrasted with conceptual <strong>design</strong>s showing<br />
overhead (plan) view and street (section or profi le) view. Additional<br />
descriptions and details for incorporating sustainable, cultural, and<br />
historically relevant <strong>design</strong> <strong>elements</strong> into the corridor right-of-way<br />
are included in the chapters that follow, as well as in the appendices.<br />
These include planting lists, trees, iconography, and site amenities and<br />
furnishings such as fencing, benches, and street light fi xtures.<br />
Rather than present a prescriptive <strong>design</strong> solution for each location, these<br />
<strong>design</strong>s present a possible combination of Design Elements and Best<br />
Practices that would enhance the site with a common natural, cultural, and<br />
historic theme that characterizes the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong>.<br />
Green infrastructure <strong>elements</strong> have also been incorporated into the<br />
concepts, including bio-infi ltration, parkway rain gardens, and permeable<br />
pavement. Specifi c applications of the practices for development proposals<br />
should use the best arrangement and selection of <strong>elements</strong> for the<br />
particular development site as determined through a thorough analysis<br />
and assessment of the site and its context. All <strong>design</strong>s should also consider<br />
sight lines, distance, and safety of all users when placing landscaping and<br />
other above-ground improvements in the right-of-way.<br />

FREEWAY<br />
Planning and <strong>design</strong> along freeway corridors<br />
in the <strong>Historic</strong> <strong>District</strong> should be conducted<br />
following TxDOT standards and incorporate,<br />
as appropriate, the Design Elements and<br />
Best Practices presented here and detailed in<br />
subsequent chapters. Safe travel ways and<br />
clear sight lines are of primary importance and<br />
all <strong>design</strong> decisions should defer to the safety<br />
of the user. While Freeways are dominating<br />
features of the landscape, the impact of freeway<br />
traffi c and infrastructure on the surrounding<br />

environment and communities may be<br />
greatly reduced using appropriate <strong>design</strong> and<br />
engineering practices.<br />
•<br />
•<br />
Architectural screening, sound walls, and<br />
woodland buff ers can be used to att enuate<br />
the increased noise and visual impact<br />
caused by freeway traffi c.<br />
Natural landforms can help add natural<br />
visual interest and screen unsightly uses or<br />
features.<br />
•<br />
•<br />
Bio-infi ltration may be used to capture<br />
and treat stormwater runoff from Freeway<br />
associated pavements.<br />
Native landscapes, including ground cover,<br />
shrubs, and trees (woodland buff er), can be<br />
installed outside of sight triangles per TxDOT<br />
recommendations. A maintenance edge may<br />
be applied along areas where roadway safety<br />
and sight lines are a concern.<br />
The existing Freeway scenario site at IH-610 and<br />
Clinton Drive demonstrates landscape practices<br />
that are ineffi cient in energy and resource<br />
consumption, do not exemplify the culture and<br />
history of the <strong>District</strong>, and do little to enhance the<br />
visual interest of the corridor. Large expanses of<br />
turf grass require maintenance out of proportion<br />
to the ecological services provided and do not<br />
evoke a native coastal <strong>Texas</strong> landscape. Views<br />
from the freeway, particularly those of industrial<br />
uses, are contrary to the desired character and<br />
qualities of the <strong>District</strong>.

Design Elements
DESIGN ELEMENTS<br />
Design Elements refer to materials, amenities, and details that refl ect local spirit, culture, history, and character.<br />
This section includes recommendations for various <strong>elements</strong> covered by the standards including pavements,<br />
plantings, and street furnishings that are intended to emulate the natural and cultural character of <strong>Texas</strong><br />
and the <strong>Historic</strong> <strong>District</strong>. As such, Design Elements should incorporate characteristics from the surrounding<br />
<strong>District</strong> context (form, color, materials, natural history, texture, and pattern) in the <strong>design</strong> and location of<br />
these Design Elements across the landscape.<br />
The Design Elements are presented here as options to be used where<br />
feasible and appropriate rather than as mandatory components of every<br />
community and corridor. As such, the Elements represent the style and<br />
character that such amenities should emulate. They are not intended to<br />
remove <strong>design</strong> fl exibility but to suggest the style and character being<br />
targeted in the <strong>District</strong>. In some cases the details and diagrams presented<br />
here are conceptual and do not represent specifi c products off ered in the<br />
marketplace. In other cases, specifi c products have been presented as<br />
examples of the general desired character and style and do not represent<br />
an endorsement or preference for a particular vendor or product.<br />
While these practices require creative and open-minded thinking on the<br />
part of the partners, communities, and developers working within the<br />
<strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong>, they can be <strong>design</strong>ed into not only the<br />
corridors for which they were selected but into almost any development<br />
area. However, it is essential that the Design Elements are examined<br />
individually and in combination so that an appropriate and representative<br />
aesthetic results from the <strong>design</strong> process. All <strong>design</strong>s should also consider<br />
sight lines, distance, and safety of all users when placing landscaping and<br />
other above-ground improvements in the right-of-way.<br />

they will also require supplemental irrigation. Consult your local nursery for other species adapted to the<br />
<strong>District</strong>. As with all landscaping, consider vegetation that is appropriate to local conditions and standards,<br />
such as allowing planting to occur with pipeline easements, and require long term management plans to<br />
increase the chances of planting success. Prescribed burning is the best vegetation management option<br />
for native or adapted species, but this will not be possible in all areas.<br />

REGIONAL PROJECT STARS MONUMENT<br />
■<br />
■<br />
■<br />
The largest of the Project Stars monuments is intended to be used along<br />
the sides of freeways and integrated into bridges.<br />
The regional monuments are 77 feet tall and constructed of a base with<br />
cast stone and brick veneers. A three-dimensional star is held aloft by<br />
four metal columns.<br />
Estimated Installed Cost: $2,242,500.00<br />

IMAGE: HARRIS CO PRECENT 2 PROJECT STARS: ICON DESIGN & GUIDELINES<br />
Iconography should be applied in a context-sensitive manner throughout the <strong>San</strong><br />
<strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> to provide clear wayfi nding and branding. Specifi cally,<br />
these monuments should be installed at Project Stars sites. Iconic monumentation, art<br />
and signage may be used to establish focal points along corridors and at signifi cant<br />
thresholds to reinforce the overall importance and legacy of <strong>San</strong> <strong>Jacinto</strong>. The <strong>Texas</strong> Star is<br />
the primary icon and can be incorporated into many of the Design Elements presented<br />
in this chapter. A fi ve-pointed star should be used in two-dimensional applications, and<br />
a nine-pointed star should be used in three-dimensional applications.<br />

ICONOGRAPHY<br />
ICONS<br />
■ The fi ve-pointed lone star, and the colors red, white, and blue, make up<br />
the <strong>Texas</strong> State fl ag and are the most iconic images in <strong>Texas</strong>.<br />
■ The fl ag most commonly associated with the Batt le of <strong>San</strong> <strong>Jacinto</strong> was<br />
presented by the ladies of Newport, Kentucky to Sherman’s Newport<br />
Volunteers. It depicts Lady Liberty holding a spear and a banner that<br />
reads “Liberty or Death.”<br />
■ The song “The Yellow Rose of <strong>Texas</strong>” refers to a woman named Emily D.<br />
West who was seized by Mexican forces and supposedly seduced General<br />
<strong>San</strong>ta Anna. Because she was mulatt o the song’s writers referred to her<br />
as a “yellow rose”. The legend credits her with distracting <strong>San</strong>ta Anna<br />
during the Batt le of <strong>San</strong> <strong>Jacinto</strong>, which allowed General Sam Houston’s<br />
forces to catch the Mexican forces off guard.<br />
The images below depict the symbols most closely associated with the <strong>District</strong>. Every<br />
attempt should be made to reference these symbols in the built features within the corridors.<br />
The fi ve-pointed star is the most important of these symbols and should be given<br />
priority when incorporating them into a <strong>design</strong> element.<br />

LIGHTING<br />
Street Light (20’-35’ height)<br />
■ Taller poles have extended arms which allow the light source to be positioned<br />
over the roadway. Refl ectors in the luminaire direct light downward.<br />
■ The taller height of the pole allows the fi xtures to be spaced further apart.<br />
■ The decorative arm and teardrop luminaire replace the conventional ‘cobrahead’<br />
fi xture for a look that is distinctive to the <strong>District</strong>.<br />
■ Arms for mounting banners and fl ags should be provided.<br />
■ A custom emblem should be incorporated into the banner arm and light pole<br />
base.<br />
■ Consider LED for energy effi ciency and light quality / color rendition in<br />
selection of luminaires and light sources.<br />
■ Hurricane wind stresses should be considered in <strong>design</strong> of pole and footing.<br />
Recommended Manufacturer/Model<br />
■ Holophane/Tear Drop series (CenterPoint Standard)<br />
■ Rolled Steel Shaft and Washington Style Aluminum Base (CenterPoint ‘River<br />
Oaks’ Standard)<br />
■ Color: Black<br />
■ Estimated Installed Cost: ~$6000 (c.2010)<br />
■ Fiscal Note from CenterPoint Energy: unit prices per installation are diffi cult<br />
to estimate due to <strong>design</strong> (luminaire, pole, watt age, system voltage) and<br />
location (residential, collector, thoroughfare, open ditch, curb / gutt er, etc.).<br />
■ Installation Note from CenterPoint Energy: construction credits are available<br />
for new lighting installation. Retrofi ts (removing old and installing new<br />
lighting) require the requestor to pay full labor and material costs.<br />
■ CenterPoint Energy creates lighting solutions in accordance with IES<br />
(Illumination Engineering Society of North America) recommendations and<br />
according to the road type, characteristic, width, and surface. State highways<br />
and freeways are generally lighted by TxDOT. Street lighting on farm-tomarket<br />
roads may or may not be provided through CenterPoint Energy.<br />
Due to recent changes at TxDOT, CenterPoint Energy only provides new<br />
overhead street lighting on TxDOT right-of-way projects (overhead street<br />
lights mounted on wood poles). Existing TxDOT underground street lighting<br />
(street lights served by underground conductors and mounted on steel poles)<br />
will be owned, operated and maintained by CenterPoint, however, they can<br />
not be relocated, modifi ed or converted to a new pole or light type.<br />
64 │ DESIGN ELEMENTS<br />
Light poles and lighting fi xtures can be the most visible features in a streetscape. The<br />
selections for these <strong>elements</strong> should reinforce the historic qualities of the <strong>District</strong> with<br />
their style and ornamentation. Designers should coordinate their plans with CenterPoint<br />
Energy, which works with communities to select and fund the installation of lighting.<br />
Communities should also consider fi xtures and solar panel strategies to reduce energy<br />
consumption. According to CenterPoint Energy, three new Holophane post top decorative<br />
fi xtures which are Dark Sky compliant will soon be available.
LIGHTING<br />
Pedestrian Light (12’-15’ height)<br />
■ The shorter pole provides a bett er scale for spaces with frequent pedestrian<br />
traffi c.<br />
■ Shorter poles will typically require more frequent spacing.<br />
■ The short pole and post-top light confi guration provides improved<br />

PAVERS<br />
Clay brick pavers Ironspot<br />
Clay Brick Pavers<br />
■ Once fi red, clay is one of the longest lasting paving materials available.<br />
■ Clay pavers are created by either pressing the clay into molds, or by<br />
extruding the clay through a die and wire-cutt ing them to size. Wire<br />
cut pavers often have a higher coeffi cient of friction which is good for a<br />
walking surface, but molded pavers may off er more textural options.<br />
■ Clay pavers can either be sand-set onto a gravel sub-base for a fl exible<br />
pavement, or mortar-set onto a concrete sub-base for a rigid one.<br />
■ A herringbone patt ern distributes wheel loads the best and should be<br />
used for vehicular areas.<br />

66 │ DESIGN ELEMENTS<br />
Poured-in-place concrete ($5/sf) and hot-mixed asphalt ($2.5/sf) are the most commonly used surfacing types due to very low<br />
initial installation cost. These two surface types continue to be used for many applications. However, individual unit pavers are a<br />
good alternative to these traditional materials in applications where aesthetics, stormwater infi ltration, and long-term durability are<br />
important. When set into a sand base, the unit pavers create a fl exible surface capable of handling shifting subgrade conditions<br />
without cracking. The primary paver materials are clay or precast concrete, and a variety of shapes and colors are available. Pavers<br />
also provide a much more fl exible material as it relates to integrating creativity and artistry into the paved surface, whether through<br />
<strong>design</strong>, orientation or color. The <strong>Texas</strong> star, a natural landscape mosaic, and historic scenes can be created using pavers.<br />

Permeable Unit Pavers<br />
■ Permeable unit pavers are available in clay and precast concrete and<br />
provide the best infi ltration rates of all permeable paving systems.<br />
■ Infi ltration occurs in the joints between individual units. An open-graded<br />
gravel is required for the sub-base.<br />
■ Narrow jointed pavers should be used for areas with high pedestrian<br />
traffi c to minimize confl icts with high heels and canes.<br />
■ Larger jointed pavers should be used for vehicular areas where increased<br />
infi ltration rates will be helpful.<br />
■ L-shaped, or other interlocking paver type should be used for vehicular<br />
areas where heavy wheel loads and turning movements will need to be<br />
resisted.<br />

LANDSCAPE<br />
Landscape is the fi rst section of these Best<br />
Practices because natural <strong>elements</strong> provide<br />
the foundation around which all other<br />
features are <strong>design</strong>ed. These natural <strong>elements</strong><br />
include hydrologic and geologic conditions<br />
as well as biological features such as plants<br />
and animals.<br />
The Best Practices in this section seek to restore<br />
a balance between the built environment<br />
and the natural features within it. When this<br />
balance is achieved, natural features can be<br />
a resource and an amenity to urban spaces.<br />
In all cases, however, it is critical to consider<br />
the safety and security of people, such as the<br />
preservation of sight distance, sight lines, and<br />
view triangles at intersections, medians, and<br />
other areas along corridors where visibility is<br />
paramount.<br />
These landscape practices address important<br />
system-level concepts such as plant<br />
selection, water conservation, and long-term<br />
maintenance.<br />
Best Practices for trees are given special<br />
att ention because no other landscape feature<br />
has the ability to transform the urban<br />
environment in the way that trees can. The<br />
practices here describe a few of the important<br />
roles that trees can play in urban spaces.<br />
Requirements for properly integrating and<br />
protecting trees are also presented.<br />
Ground-level vegetation also has an important<br />
role to play in the urban environment. The<br />
practices here demonstrate a few of their<br />
benefi ts.<br />
LA IN LI CI AM<br />
Landscapes are often thought of as the green “stuff” that fi lls the voids in our built environment. Through<br />
careful planning and <strong>design</strong>, landscapes can be more than a beautiful backdrop. When properly integrated,<br />
soils can remove pollutants from runoff, rainfall can be harvested for reuse, and plants can literally breathe<br />
life back into desolate urban spaces, reactivate the landscape, and provide a more cultural and historically<br />
relevant setting for the <strong>District</strong>.<br />
Consideration should also be given to high<br />
winds and hurricane conditions, which tend<br />
to uproot shallow-rooted trees.<br />
Recommended Suggested Strategies and<br />
supplemental information are also provided<br />

Design landscape planting materials, beds, and vegetation<br />
for multiple benefi ts.<br />
Conventional landscaping tends to serve a<br />
single purpose: to provide aesthetic amenities<br />
to the roadside. Landscapes, however, can<br />
and should be planned and <strong>design</strong>ed to serve<br />
multiple purposes including aesthetics, a<br />
sense of place, stormwater management, and<br />
shading. Landscaped areas that break up large<br />
areas of paved surfaces and provide cooling<br />
shade can help reduce the heat island eff ect<br />
in communities and along roadways. If the<br />
areas are not within two miles of an airport,<br />
landscaping can also provide wildlife habitat<br />
that may include nesting sites, food, cover,<br />
and shelter for wading birds, songbirds,<br />
mammals, and other animals.<br />

Roadside native plantings evoke a historic landscape.<br />
Native and adaptive landscapes can be attractive and require less<br />
maintenance than conventional turf grass.<br />
Natural vegetation and edges are more benefi cial to environmental<br />
resources.<br />
IMAGE: CONSERVATION DESIGN FORUM IMAGE: CONSERVATION DESIGN FORUM IMAGE: CONSERVATION DESIGN FORUM<br />
Plants native to the biological region<br />
(‘bioregion’) should be maintained or<br />
restored within the <strong>District</strong> to promote a<br />
regional identity and sense of place. Many<br />
native plants will only thrive as part of an<br />
ecological system that is managed to replicate<br />
the natural conditions the plants need,<br />
such as annual controlled burning, invasive<br />
species removal, and a stable hydrology.<br />
Native vegetation will also require diff erent,<br />
less intensive and generally less expensive<br />
maintenance practices than conventional<br />
plantings with exotic species.<br />
Plant material should be allowed to grow<br />
and develop in a natural, organic state in<br />
terms of shape, size and character where<br />
natural character will not compromise safety<br />
and security. Once established the general<br />
maintenance that should be performed<br />
should be limited to:<br />

Promote a sense of place by planting native and adapted, low<br />
input vegetation as part of the overall landscape and site plan.<br />
Minor pruning for visual and physical<br />
safety at drives, crossings, and trail and<br />
pathway clearances.<br />
Regular monthly trash pickup.<br />
Distressed and dead plants should be<br />
allowed to decay naturally in certain<br />
naturalized landscapes, except where<br />
safety and security may be compromised.<br />
Plant replacement should take place<br />
only as a means to mitigate disturbances<br />
or density loss due to pollution or other<br />
natural or man-made causes.<br />

Whether planting along roads, highways,<br />
or parks, a successful strategy for planting<br />
native and adaptive plants requires the<br />
proper preparation of a planting bed with<br />
appropriate soils that allow roots easy access<br />
to oxygen, nutrients, water, and room to<br />
spread and expand. Other recommendations<br />
include:<br />
■<br />
LA IN LI CI AM<br />
Prepare, install, and maintain planting beds using appropriate<br />
practices to maximize success of landscape plantings.<br />
A minimum of 12” of amended topsoil<br />
containing a mix of sand and organic<br />
matt er can optimize plant growth. Check<br />
soil nutrient and pH levels before adding<br />
mineral or nutrient amendments.<br />
84 │ BEST PRACTICES<br />
■<br />
■<br />
Provide trees with a clear, permeable<br />
surface area. Where possible, an area equal<br />
to the size of the expected tree canopy is<br />
desired. In an urban context, ensure that<br />
the clear tree planting area is a minimum<br />
6’ wide by 6’ deep continuous trench of<br />
planting soil.<br />
Where rooting area is limited, such as<br />
in parkways or planters, use strategies<br />
such as connected planting beds, rooting<br />
breakouts under parking, or walkways<br />
suspended on root-permeable soils<br />
(structural soil) to extend rooting space,<br />
provide air and water to the tree, and<br />
increase plant vigor.<br />
Appropriately <strong>design</strong>ed planting beds will enhance success of vegetation.<br />
Properly constructed and maintained beds will result in fl ourishing<br />
landscapes.<br />
Planting beds can be as broad as the context allows and <strong>design</strong>ed to<br />
compliment the surrounding built environment.<br />

Plant both native and adapted species derived from regional stocks<br />

Plants should be selected based on their ability<br />
to grow well in the local climate and withstand<br />
harsh roadside conditions. They should<br />
also have low maintenance requirements<br />
(minimal mowing, supplemental watering,<br />
and inputs of fertilizers, herbicides and<br />
pesticides.) Specify native and adapted plant<br />
and tree species appropriate to the specifi c<br />
site, att ributes, and microclimatic conditions<br />
rather than exotic, non-native species (refer<br />
to the Design Elements for plant and tree<br />
lists). These species contribute to biodiversity,<br />
habitat, water quality, and aesthetic objectives<br />
for the <strong>San</strong> <strong>Jacinto</strong> <strong>District</strong>. Non-native<br />
species or species native to other regions of<br />
North America may be included for their<br />
ornamental or functional qualities; however,<br />
avoid invasive or overly aggressive species<br />
that tend to crowd out native species and<br />
eventually dominate planting beds.<br />

of grass, sedge, rush, and forbs derived<br />
from parent generations that originated<br />

Select plants adjacent to paved surfaces<br />
according to anticipated stressors such<br />
as soil compaction, heat and drought<br />
conditions, strong winds, shade, minimal<br />
water infi ltration, and polluted soils and<br />
rain water runoff .<br />
Select plant species based in part on low<br />

The successful establishment of native<br />
and adapted species requires a burning<br />
management regimen that stimulates the<br />
growth of these and other desirable species<br />
while reducing the survival of non-natives<br />
and invasive species that can overtake a<br />
planting area. Burn management returns the<br />
carbon stored in the plant cells to the ground,<br />
and primarily releases water vapor and<br />
carbon dioxide to the atmosphere. As such,<br />
burning is a bett er practice for improving air<br />
quality as it releases much less carbon and<br />
pollutants than does the regular mowing<br />
regime practiced along most roadways.<br />
The use of native and adaptive species<br />
and burn management regimen should be<br />

INFRASTRUCTURE<br />
LA IN LI CI AM<br />
Our habitation requires a network of support infrastructure – roads, energy, communications, water<br />
management, waste management, etc. When these networks are <strong>design</strong>ed separately for a single purpose<br />
the result is often redundancy and waste. Where feasible and practical, infrastructure should achieve<br />
multiple benefi ts and support the function and aesthetics of the surrounding landscape.<br />
The infrastructure of the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong><br />
<strong>Historic</strong> <strong>District</strong> includes a network of paved<br />
surfaces, systems for handling stormwater<br />
runoff , and the utilities that provide people<br />
with potable water, power, and other<br />
services.<br />
Infrastructure does not need to be ugly. It is<br />
also not necessary to pollute the environment<br />
and disrupt natural systems to achieve the<br />
benefi ts that infrastructure provides. The Best<br />
Practices in this section provide <strong>design</strong>ers<br />
with a number of tactics to minimize<br />
environmental impacts and achieve multiple<br />
benefi ts from the everyday infrastructure<br />
around us.<br />
Sculpting the ground plane is often necessary<br />
to build roads and structures, but it can also<br />
disrupt hydrology, destroy soil structure, and<br />
make development appear incongruous with<br />
the surrounding landscape. Landform Best<br />
Practices suggest how grading activities can<br />
make a positive contribution to the <strong>District</strong>.<br />
Paved surfaces are impervious and therefore<br />
shed excess stormwater runoff into our<br />
streams and waterways. They also discharge<br />
pollutants such as fi ne sediments and oils,<br />
and can contribute to urban heat island<br />
eff ects when darker surfaces are used. Paving<br />
practices highlight these issues and establish<br />
strategies for addressing them.<br />
Water Best Practices illustrate measures that<br />
can be employed to minimize detrimental<br />
eff ects when stormwater is discharged from<br />
impervious surfaces.<br />
Utility Best Practices seek to reconcile the<br />
spatial requirements for above and belowground<br />
utilities with the aesthetic goals for<br />
<strong>District</strong> corridors.<br />
Decisions for <strong>design</strong>ing, locating, and<br />
installing utilities and infrastructure should<br />

LIGHTING<br />
Street lights are the most visible lighting<br />
feature in the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong><br />
and account for the majority of applications.<br />
Street lights can be characterized by the type<br />
of road they are illuminating. Generally,<br />
corridors with higher travel speeds are lit<br />
by taller and more widely spaced lighting<br />
fi xtures.<br />
What is appropriate for a driver in a car,<br />
however, is not always good for a pedestrian<br />
on a sidewalk or a cyclist. Streets that<br />
have important pedestrian environments<br />
have a diff erent set of lighting needs to be<br />
accommodated. Retail areas with storefronts<br />
also benefi t from a unique distribution of<br />
light.<br />
Light can provide visual interest in the<br />
landscape as well. For many visitors to the<br />
<strong>District</strong>, one of the most striking views is<br />
created by the multitude of individual lights<br />
that adorn the oil refi neries and chemical<br />
plants. What can appear to be a blighted<br />
industrial landscape during the day is<br />
transformed into an ethereal visual spectacle<br />
at night. With the addition of artistic lighting<br />
displays, industrial areas could become<br />
unlikely tourist att ractions.<br />
All of these needs and opportunities should<br />
be balanced with the hazards of energy<br />
waste and light pollution. The following best<br />
practices provide a few measures that will<br />
help to achieve this goal.<br />
LA IN LI CI AM<br />
By some estimates, street lighting accounts for approximately 40% of a typical American city’s electrical<br />
use. And while there is little doubt that lights are critical for making urban areas safe, there is a shifting public<br />
awareness to the issues of energy consumption and light pollution.<br />

Provide lighting which promotes a feeling of<br />
safety and comfort at night with consistent<br />
illumination and without excessive light<br />
levels or glare. Ensure that light corners,<br />
pockets, out of the way spaces and areas<br />
that are not visually accessible from streets<br />
or windows are well lighted to enhance<br />
security. Consider motion sensor lighting<br />
where possible to enhance security while<br />
minimizing lighting spaces when it is rarely<br />
needed.<br />
[<br />
Suggested Strategy:<br />
]<br />
Directional + Full Cutoff Lighting<br />
(Appendix A)<br />
110 │ BEST PRACTICES<br />
Properly aim lights and strategically place<br />
shade trees and plants to help prevent<br />
unwanted glare into adjacent properties<br />
and natural areas (light trespass), limit sky<br />
glow (light pollution), and match the proper<br />
brightness with the application. Protect<br />
the night sky by directing illumination<br />
downward onto the ground or target and<br />
away from observes via shielded or full cutoff<br />
(FCO) lamp housings. Use low-refl ectance<br />
surfaces to reduce glare and luster. When<br />
lighting signs and plantings, use low-angle<br />
spotlights that are low intensity, shielded,<br />
and directed down and away from adjacent<br />
properties and streets.<br />
Pedestrian lighting is imperative for safety..<br />

Make effi cient use of energy for lighting applications.<br />
Minimize lighting by illuminating only areas<br />
as required for safety and comfort. Encourage<br />
the use of high-effi ciency lighting to reduce<br />
energy consumption and increase lamp<br />
longevity, such as with advanced LED warm<br />
light technology. When security lighting is<br />
not required, lighting should use motion<br />
sensors or daylight sensors to turn off or<br />
be automatically controlled to turn off after<br />
curfew hours, which will help reduce night<br />
sky illumination and conserve energy.<br />
Where practical, direct lighting to surfaces<br />
that will refl ect diff used lighting into wide<br />
areas to improve illumination and reduce<br />
LA IN LI CI AM<br />
the number of fi xtures and amount of lighting<br />
(and energy) used. This technique is especially<br />
eff ective at illuminating spaces under canopies,<br />
or other overhangs. Refl ective-type lighting<br />
fi xtures can reduce or eliminate glare and<br />
increase light dispersal. Care must be taken<br />
to balance the benefi ts of diff used, scatt ered<br />
light with the detriments of night sky light<br />
pollution. Use high effi ciency (metal halide or<br />
high pressure sodium lamps) or alternatively<br />

CIRCULATION<br />
Pedestrians and bicyclists require many<br />
of the same things that drivers of vehicles<br />
do in order to navigate through the cities<br />
and region. Both rely upon fl at, dedicated<br />
travel routes that are properly marked. But<br />
pedestrians and bicyclists are uniquely<br />
vulnerable on congested urban streets and<br />
require additional safety considerations.<br />
By providing adequate space for walking<br />
and off ering <strong>design</strong>ated bicycle lanes, streets<br />
can be made truly livable. The following Best<br />
Practices address strategies for crosswalks,<br />
sidewalks, and bicycle routes and facilities.<br />
LA IN LI CI AM<br />
In order to create environments that support walkable neighborhoods and thriving downtowns, <strong>design</strong>ers<br />
must put as much thought into the <strong>design</strong> of the sidewalk and travelways for the pedestrian as they put into<br />

Improve pedestrian safety at vehicle crossings.<br />
Pedestrian crosswalks and routes at vehicle<br />
crossings should be delineated with a<br />
contrasting surface material or other <strong>elements</strong><br />
to distinguish walking areas and to alert and<br />
caution drivers. Suggested practices include<br />
detectable warning surfaces, directional<br />
textures, warning signs or lights, audible<br />
signals, or paint markings. A change in<br />
paving material or color can also indicate<br />
a change in conditions, such as modular<br />
pavers, integrated color concrete or asphalt,<br />
or stamped concrete or asphalt. As suggested<br />
in other Best Practices, permeable pavements<br />
are encouraged. Also consider using bollards<br />
or other separation devices at pedestrian<br />
crossings, such as on medians or islands<br />
within long pedestrian crossings, to increase<br />
the visibility of the crossing location and<br />
improve pedestrian safety.<br />

Provide curb bulb outs or corner curb extensions with landscaped<br />
stormwater planters at gateway and main street corners.<br />
Curb extensions can eff ectively narrow the<br />
street at pedestrian crossings by shortening<br />
the crossing distance, improve the ability<br />
of pedestrians and motorists to see each<br />
other, and reduce the time pedestrians are<br />
in the roadway. Curb bulb outs can also<br />
be used to promote traffi c calming, which<br />
increases pedestrian safety. These features<br />
can also expand the landscape, amenities,<br />
and walkable zone. As a distinguishing<br />
characteristic, the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong><br />

walking as part of a healthier lifestyle.<br />
Destinations include transit stops, places of<br />
employment, parks and open space, recreation<br />
facilities, schools, churches, temples and<br />

be clear of all vertical obstructions, such<br />
as utility boxes, fi re hydrants, and other<br />
<strong>elements</strong>. Relocation of existing utilities may<br />
be required to meet safety considerations. All<br />

Where moderate bicycle traffi c is expected,<br />
and permitt ed, provide signage along the<br />
road to identify it as a shared roadway. Shared<br />
roadways should be the preferred route for<br />
bicyclists between two regional destinations.<br />
Traffi c control devices along shared roadways<br />
should be adjusted to give greater priority to<br />
bicyclists, as opposed to alternative streets.<br />
Care should be given to select pavement<br />
materials and utility structures (i.e. drainage<br />

roadways may also have larger curb-side<br />
lanes to accommodate bicyclists, though<br />
AASHTO does not recommend traffi c lanes<br />
over 14 feet wide. Shared roadways should<br />
not be located on streets with diagonal (headin)<br />

Dedicated bike lanes can be provided where<br />
frequent bicycle traffi c is expected. Striped<br />
bike lanes create an environment where<br />
bicycle and vehicle movements are more<br />
predictable. They also make it less likely that<br />
motorists will stray into the path of a bicyclist.<br />
Bike lanes should be one-way facilities and<br />
should carry bike traffi c in the same direction<br />
as the adjacent motor vehicle traffi c. (Consult<br />
AASHTO’s Guide for the development of<br />
bicycle facilities.)<br />
Bike racks should be located in downtown<br />

AMENITIES<br />
Wayfi nding and interpretive signage<br />
are important amenities in a streetscape<br />
environment. Wayfi nding signage that is<br />
tailored to pedestrians can supplement<br />
existing street signs which are usually<br />
<strong>design</strong>ed for motorists. Custom wayfi nding<br />
signage can link together distant sites and<br />
reinforce a regional identity in a way that<br />
standard street signs can’t. Once visitors<br />
have arrived at a site, interpretive signage<br />
can be used to identify and describe specifi c<br />
features. Furnishings such as benches and<br />
drinking fountains also encourage pedestrian<br />
travel through a corridor.<br />
Cultural amenities are what will truly<br />
distinguish the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong><br />
<strong>District</strong> from other places in the Houston<br />
metropolitan area. Public art that draws<br />
upon the primary cultural, industrial, and<br />
environmental themes of the <strong>District</strong> will<br />
help to create unique environments. Art<br />
installations will also broaden the appeal<br />
of the district to a wider group of visitors.<br />
Artistic contributions can be solicited from<br />
youths and other groups that are often<br />
disenfranchised.<br />

APPENDIX A - STRATEGIES<br />
The <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> Corridor Standards includes 39 Best Practices for Landscape,<br />
Infrastructure, Lighting, Circulation, and Amenities. Some of these practices refer to a particular “Suggested<br />
Strategy” intended to provide implementation guidance including how and why a particular strategy is<br />
important. These and other strategies are included in this Appendix. Information presented includes a<br />
defi nition of the strategy, applicability, benefi ts, and maintenance, <strong>design</strong>, and cost considerations.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 133
Native Landscape Systems<br />
Defi nition<br />
Establishment of native vegetation in<br />
landscaped areas and often as a component of<br />
other stormwater best management practices<br />
such as fi lter strips, bioretention features, and<br />
green roofs. Deep root systems (3 to 10 feet<br />
or more) help fi lter and absorb rainwater. A<br />
fi lter strip is an area with dense, preferably<br />
native vegetative cover (they can also be<br />
planted with turf grass) that is used to slow,<br />
fi lter, and absorb runoff from impervious<br />
areas. Use native plant and tree species that<br />
are adapted to urban applications.<br />
Applicability<br />
Native landscapes are appropriate for nearly<br />
all new and retrofi t landscapes on individual<br />
lots and <strong>District</strong>-wide. Native landscapes can<br />
be used for rainwater management practices,<br />
parks, green roofs, residential courtyards,<br />
and gardens.<br />

Maintenance Considerations<br />
Natural landscaping requires less irrigation,<br />
mowing, fertilizers, and pesticides than<br />
conventional landscapes. Annual mowing<br />
or controlled burning are appropriate for<br />
natural landscapes. Initial watering and<br />
herbiciding may be necessary in the fi rst 2-3<br />
years after planting, but once established (3-4<br />
years) these needs are greatly diminished.<br />
Cost Considerations<br />
Costs vary from project to project depending<br />
on area, plant selection, and <strong>design</strong><br />
features. In general, native landscapes cost<br />
approximately $3000 to $6000 per acre to<br />
install, compared to $7500 to $15,000 for<br />
conventional turf. These costs consider fi rst<br />
establishment costs, such as mowing and<br />
watering, and refl ect planting seed as opposed<br />
to native plant plugs. Maintenance costs after<br />
establishment are on average between $1600<br />
and $1800 per acre for native landscapes,<br />
compared to $5500 to $6500 for turf grass.<br />
Maintenance costs for native landscapes are<br />
slightly less than turf for the fi rst fi ve years,<br />
and signifi cantly less thereafter, when annual<br />
burning or other control method is the only<br />
maintenance needed.<br />
Design Considerations<br />
■<br />
■<br />
■<br />
■<br />
■<br />
Design should be tailored to site<br />
characteristics including topography,<br />
soils, drainage, and solar exposure.<br />
Some local “weed” ordinances may need<br />
to be amended to allow native and taller<br />
vegetation.<br />
Plant diversity and health is maximized<br />
by annual burning. Plots may be mowed<br />
and then burned to prevent spread of fi re<br />
on small sites.<br />
On compacted or disturbed soils,<br />
amendment may be necessary to increase<br />
organic content, improving success of<br />
plant establishment. Good soil preparation<br />
vastly improves the appearance and vigor<br />
of plantings in the fi rst season.<br />
Filter strips must be sized and <strong>design</strong>ed to<br />
account for drainage area, slope and soils.<br />
The highest eff ectiveness is achieved for<br />
small (1 or 2 year) storm events when the<br />
drainage area is not greater than 4 or 5<br />
times the area of the fi lter strip.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 135
Rainwater Harvesting & Reuse<br />
Defi nition<br />
Downspouts from roof runoff , which are<br />
typically routed to the municipal sewer<br />
system, can be directed into a vessel specially<br />
<strong>design</strong>ed to capture and temporarily store<br />
rainwater for various uses, including<br />
greywater reuse and landscape irrigation.<br />
Applicability<br />
Rain collectors and cisterns can be used at a<br />
variety of scales on new and retrofi t buildings.<br />
The area and confi guration of the roof, as<br />
well as the desired volume of collected<br />
water, will determine the size and location<br />
of the vessels. As the cost of potable water<br />
rises, and as the availability of groundwater<br />
sources decreases, collecting and using this<br />
‘free’ water becomes an economic necessity,<br />
both on an individual and a regional scale.<br />

Reduces annual runoff volumes fl ows into<br />
the sewer system and streams and rivers,<br />
which can also help reduce downstream<br />
fl ooding.<br />
Conserves water for reuse (e.g. irrigation<br />
of lawns and gardens).<br />
Collected water can be used to irrigate<br />
landscapes or for some internal building<br />
uses such as toilet fl ushing, or it can be<br />
released into the sewer system between<br />
storm events.<br />
A mesh fi lter or screen can be inserted at<br />
the top of the collector to prevent leaves<br />
and other debris from entering.<br />
One inch of rainfall over 1,000 square feet<br />
of roof area is equivalent to 625 gallons of<br />
rainwater.<br />
Rain collectors can be used in combination<br />
with bioretention, green roofs, and other<br />
practices to increase stormwater benefi ts.<br />
Larger cisterns in some sett ings may be<br />
used to provide greywater for use in toilet<br />
fl ushing and other non-potable uses.<br />

Occasional draining and cleaning may<br />
also be necessary to remove debris, such<br />
as leaves, that may fall into the vessel.<br />
Draining and cleaning will also prevent<br />
stagnation and buildup of algae.<br />
Rain collectors should be sealed during<br />

breeding.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 137
Urban Tree Protection Measures<br />
Defi nition<br />
One of the biggest obstacles to growing<br />
healthy trees in urban environments is soil<br />
compaction. In parkway areas, compaction<br />
can result from frequent foot traffi c and<br />
from the installation of adjacent curbs and<br />
sidewalks. When soils are compacted they<br />
prevent water and air from reaching the<br />
tree’s roots. Urban trees can be protected in<br />
several ways. Concrete curbs and railings<br />
can be installed around tree planters to<br />
discourage foot traffi c. Where space is tight,<br />
trees can be installed in pits with steel tree<br />
grates. Subgrade conditions can be improved<br />
through the use of root paths and structural<br />
soil.<br />
Applicability<br />
Street trees should only be located after a<br />
close examination of existing utilities (above<br />
and below ground), buildings, and traffi c<br />
concerns. Existing parkway planters can be<br />
retrofi tt ed with concrete curbs or railings to<br />

Tree grates can also be used where a heavy<br />
fl ow of pedestrian traffi c is expected along<br />
the curb line (i.e. on-street parking locations).<br />
Where the construction of new sidewalks<br />

Design & Maintenance Considerations<br />
■<br />
■<br />
■<br />
■<br />
■<br />
■<br />
■<br />
Parkway planter curbs should provide<br />
enough space between them for<br />
pedestrians to access the street edge.<br />
Ornamental steel railings will require<br />
frequent painting to protect them from<br />
rusting. Aluminum railings should not be<br />
used in high impact areas, or in areas with<br />
signifi cant salt spray.<br />
In soils with low permeability, drainage<br />
needs to be provided at the bott om of tree<br />
pits to prevent saturated conditions.<br />
In urban areas, wire mesh may need to<br />
be installed within a tree pit to prevent<br />
rodents from nesting.<br />
Root paths and structural soil may be<br />
used to connect parkway tree planters to<br />
each other, or to green spaces on private<br />
property.<br />
Root paths should be spaced four feet<br />
apart in a radial fashion to connect each<br />
tree to the adjacent green space.<br />
The Urban Horticulture Institute at Cornell<br />
University has detailed specifi cations for<br />
structural soil. Care should be taken to<br />
specify similar performance parameters.<br />

Costs range from $14 to $18 for each lineal<br />
foot of poured concrete curb and $50 to<br />
$80 per lineal foot for an ornamental steel<br />
railing installed.<br />
Tree grates require a poured concrete curb<br />
to support their steel frame. The curb will<br />

Cast iron tree grates cost $15 to $25 per<br />
square foot.<br />
Costs for root paths will range from $8 to<br />

Depending on the product specifi ed and<br />
the proximity to the aggregate source,<br />
structural soil will range from $50 to $80<br />
per cubic yard installed.<br />

Porous Pavements<br />
Defi nition<br />
Porous paving materials or paver units with<br />
porous joints allow transmission of water<br />
to an aggregate base, reducing runoff rates<br />
and improving water quality. Runoff is<br />
temporarily stored in the base and slowly<br />
evaporated and released to storm sewers.<br />
When porous paving systems are installed<br />
over permeable soils, runoff volumes can be<br />
reduced. Porous unit pavers are a common<br />
type of porous pavement system that contain<br />
openings fi lled with gravel or rock chips.<br />
Porous concrete, and asphalt contain larger<br />
than typical aggregates and pore spaces to<br />
allow water percolation, but are less common.<br />
Variations on gravel pavements are a third<br />
type of permeable practice.<br />
Applicability<br />
Porous pavement is appropriate for new<br />
and retrofi t projects on existing streets, full<br />
and temporary (overfl ow and special event)<br />
parking lots, alleys, sidewalks, utility and<br />
access roads, emergency access lanes, fi re<br />
lanes, and driveways. Porous pavements are<br />

Cost Considerations<br />
Installation costs can be 1.5 - 2 times greater<br />
than conventional concrete, but may require<br />
less frequent replacement. The runoff<br />
reduction capacity of permeable paving can<br />
reduce the cost of stormwater engineering<br />

Subgrade should be graded at minimum<br />
1% slope to allow drainage.<br />
Impermeable geotextiles should be used<br />
between base and subgrade to prevent<br />
infi ltration where contaminated subgrade<br />
soils are present.<br />
Underdrains should be placed at edge<br />
of pavement to provide drainage as<br />

Bioretention Practices<br />
Defi nition<br />
Rain gardens, tree wells, and planter boxes<br />
can be <strong>design</strong>ed as vegetated stormwater<br />
bioretention features that convey, retain,<br />
cool, and cleanse stormwater before being<br />
discharged to sewer systems. They are<br />
installed in parkways, medians, and parking<br />
lot islands, and along the sides of buildings<br />
to capture roof runoff . These practices are<br />
typically <strong>design</strong>ed to allow stormwater to<br />
pond slightly and infi ltrate into the ground,<br />
or to be absorbed and evaporated into the<br />
atmosphere by vegetation. Impermeable<br />
liners should be used to prevent water from<br />
infi ltrating into the underlying soils where<br />
contaminated soils are present. Excess water<br />
is collected by a drain and discharged to<br />
storm sewers.<br />
Applicability<br />
Bioretention practices are appropriate for<br />
most new and retrofi t projects on individual<br />
lots and rights-of-way to accept runoff from<br />
roof downspouts, streets, driveways, alleys,<br />
sidewalks, and parking lots.<br />

Impermeable liners should be installed<br />
to prevent infi ltration of stormwater into<br />
underlying soils where contaminated<br />
soils are present, or where rain gardens<br />
are immediately adjacent to buildings<br />

A gravel trench with underdrain should<br />
be used to allow excess fl ow to drain into<br />
storm sewer system.<br />

Lighting Effi ciency & Pollution Control Methods<br />
Defi nition<br />
Exterior lighting systems can improve the<br />
safety of pedestrian and vehicular circulation,<br />
aid surveillance and increase perceptions of<br />
safety, and enhance retail environments. The<br />
most common type of exterior fi xture is the<br />
street light, which is available in a variety<br />
of pole heights and luminaire shapes to suit<br />
both street and pedestrian uses.<br />
By some estimates, street lights account for<br />
approximately 40% of a typical city’s electrical<br />
consumption. For this reason, energy<br />
effi ciency is an important objective for most<br />
lighting <strong>design</strong>s. Designs that greatly exceed<br />
minimum illumination standards may be<br />
wasting energy. The choice of lamp type also<br />
aff ects the amount of energy needed (watt s) to<br />
produce the required illumination (lumens).<br />
Light-emitt ing diode (LED) technologies<br />
are emerging that promise to provide<br />
more lumens per watt of energy consumed<br />
than other lamp types. LED’s also off er the<br />
advantages of a long lamp life, good color<br />
rendering, and improved directional control.<br />
144 │ APPENDICES<br />
Improperly <strong>design</strong>ed lighting systems<br />
can also contribute to light pollution. The<br />
International Darksky Association and its<br />
local <strong>Texas</strong> affi liate (www.darksky.org and<br />
www.texasida.org) describe Light Pollution<br />
as “any adverse eff ect of artifi cial light<br />
including sky glow, glare, light trespass,<br />
light clutt er, decreased visibility at night, and<br />
energy waste.” Upward facing light fi xtures<br />
are one of the primary contributors to light<br />
pollution. To address this issue, the American<br />
National Standard Practice for Roadway<br />
Lighting identifi es four classifi cations of<br />
luminaires: Noncutoff , Seimcutoff , Cutoff ,<br />
and Full Cutoff . They each allow a decreasing<br />
intensity of light (as measured in candelas<br />
per 1000 lamp lumens) above 80 degrees and<br />
above 90 degrees (from vertical). A full cutoff<br />
luminaire permits no light to leave the fi xture<br />
above 90 degrees and is the only fi xture type<br />
that does not directly contribute to light<br />
pollution.<br />

for roadway, pedestrian walkway, and<br />
bikeway lighting needs. It sets minimum<br />
horizontal light levels (on pavements) and<br />
vertical light levels (on building faces) for<br />
each classifi cation with the goal of mitigating<br />
confl icts between people and cars.<br />
Benefi ts<br />

■<br />
■<br />

■<br />
Full cutoff fi xtures eliminate direct<br />
contribution to light pollution, light<br />
trespass onto adjacent properties, and<br />
problems with glare.<br />
LED lamps have demonstrated reduced<br />
energy costs of 35-60% compared to<br />
standard high pressure sodium fi xtures.<br />
The life expectancy of LED lamps can<br />
range from 40,000 to 60,000 hours<br />
compared with an average life expectancy<br />
of 24,000 hours for high pressure sodium<br />
and 12,000 hours for pulse start metal<br />
halide lamps.<br />
LED lamps produce whiter appearing<br />
light than high pressure sodium.<br />
LED lamps distribute their light in a more<br />
controlled fashion than other lamps which<br />
can reduce light trespassing issues.<br />
Design & Maintenance Considerations<br />
■<br />
■<br />
■<br />
■<br />
Install full cutoff fi xtures without any<br />
uptilt by installing the fi xture on a rigid<br />
mounting arm without an adjustable<br />
knuckle or slipfi tt er.<br />
Full cutoff lighting may require additional<br />
poles and fi xtures overall since the<br />
individual fi xtures do not allow as much<br />
light to be dispersed at shallow angles.<br />
LED lamps are more likely to produce<br />
glare than other lamps. Design to stay<br />
within recommended guidelines for<br />
uniformity ratios (defi ned as average light<br />
level over minimum light level).<br />
The total amount of light (lumens) emitt ed<br />
by LED lamps is often less than other<br />
lamps. This may limit their use in high<br />
volume roadway applications.<br />
Cost Considerations<br />
■<br />
■<br />
Full cutoff lighting can cost as much as<br />
25% more than other types of lighting.<br />
This is directly related to the need for<br />
additional poles and fi xtures because<br />
light does not get distributed as far with<br />
full cutoff fi xtures. The individual fi xtures<br />
cost approximately the same from the<br />
manufacturer as other fi xture types do.<br />
LED lamp fi xtures can cost 10-50% more<br />
than their HPS counterparts.<br />

Traffi c Calming Measures<br />
Defi nition<br />
Traffi c calming measures such as tightened<br />
curb radii at intersections, crosswalk<br />
markings, and curb extensions reduce the<br />
potential for confl icts between people and<br />
vehicles in urban street environments. By<br />
decreasing the radius of curbs at intersections<br />
the length of crosswalks can be reduced and<br />
right turning vehicles can be forced to reduce<br />
their speed through the turn. Crosswalk<br />
markings direct the fl ow of pedestrian traffi c<br />
at intersections and make approaching<br />
drivers aware of pedestrians. Curb extensions<br />
(also known as bulb outs, or neck downs) are<br />
areas of the parkway that extend out into<br />
the road area. These occur at intersections,<br />
or mid-block crossings where they serve to<br />
reduce the crosswalk distance and enhance<br />
the pedestrian environment.<br />

■<br />
■<br />
■<br />
The radii selected for intersection corners<br />
should accommodate the largest vehicle<br />
type that will frequently turn the corner.<br />
This principle assumes that the occasional<br />
large vehicle can encroach into the<br />
opposing travel lane, or mount the curb.<br />
A minimum marking treatment should<br />
consist of high contrast painted lines in<br />
accordance with the most recent edition<br />
of the Federal Highway Administration’s<br />
Manual on Uniform Traffi c Control<br />
Devices. See (htt p://mutcd.fh wa.dot.gov/)<br />
A bett er marking treatment will integrate<br />
a separate paving material within the<br />
crosswalk area that visibly contrasts with<br />
the road surface. This approach will be<br />
more durable and last longer than painted<br />
lines which will wear away.<br />
The <strong>design</strong> of curb extensions should<br />
respect street drainage patt erns so that<br />
rain water runoff does not collect behind<br />
them.<br />
The use of curb extensions should be<br />
limited to situations where on-street<br />
parking exists.<br />

Universal Design<br />
Defi nition<br />
Universal Design involves an approach<br />
to the <strong>design</strong> and engineering of the built<br />
environment that seeks to remove as<br />
many barriers as possible for people with<br />
disabilities. Individuals are often prevented<br />
or discouraged from accessing public<br />
spaces because of visual, mobility, hearing,<br />
and learning impairments. The thoughtful<br />
application of measures to improve<br />
accessibility can remove these barriers.<br />
Not all individuals with a visual impairment<br />
are completely blind. In the United States,<br />
nearly half have limited vision. Most of these<br />
people have some memory of how the urban<br />
environment is constructed since 96% of<br />
visually impaired people in the United States<br />
developed their disability during adulthood.<br />
The Typhlo cane is the primary means by<br />
which visually-impaired people navigate<br />
the urban environment. Using the cane,<br />
individuals can locate the edges of walks and<br />
identify tactile warning strips that warn them<br />
of hazardous areas.<br />
148 │ APPENDICES<br />
Many of the people with a mobility<br />
impairment are elderly. These individuals<br />
require frequent places to sit, smooth surfaces<br />
to walk on, and handrails to navigate stairs<br />
and ramps. Ramps are probably the most<br />
visible of all accessibility measures. They are<br />
critical for providing an accessible route for<br />
people using wheelchairs.<br />
Visual cues that rely on universal <strong>design</strong><br />
symbols can assist people with hearing and<br />
learning impairments.<br />
Applicability<br />
The Americans with Disabilities Act<br />
Accessibility Guidelines (1991) establishes<br />
minimum accessibility standards for public<br />

in price between $500 and $2000 installed.<br />
Consumers should expect to pay 10-15%<br />
more for models with arm rests and<br />

Constructing a ramp can cost between<br />
$100 and $300 per lineal foot, depending<br />
upon materials and site issues.<br />
Design & Maintenance Considerations<br />
■<br />
■<br />
■<br />
■<br />
■<br />
■<br />
■<br />
Typhlo canes won’t detect objects above<br />
waist height, so <strong>design</strong>ers should eliminate<br />
projections into public walkways above<br />
27 inches in height.<br />
Tactile warning strips with truncated<br />
domes are required wherever pedestrian<br />
traffi c enters a vehicular-use area. This is<br />
usually a crosswalk at a public street, but<br />
can also be a service yard, alley, or parking<br />
lot. Tactile warnings must be a contrasting<br />
color to the adjacent pavement.<br />
Tactile warning strips are recommended<br />
at the tops of stairs - a common treatment<br />
uses recessed parallel grooves.<br />
Cross slopes on accessible routes should<br />
not exceed 2%.<br />
Avoid tactile warnings that are stamped<br />

Community Art & Local Craftsmanship<br />
Defi nition<br />
The public realm is greatly enhanced when<br />
art and craftsmanship are integrated into the<br />
<strong>design</strong> of the street environment. The <strong>San</strong><br />
<strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> is fortunate<br />
to have a rich cultural and environmental<br />
legacy that local artisans and craftsmen<br />
can draw upon. Art installations such as<br />
murals, frescoes, mosaics, and sculpture<br />
can be added to existing outdoor spaces in<br />
the district. These types of installations are<br />
generally created for the sake of the art itself.<br />
When new places are constructed, there is<br />
also an opportunity to integrate functional<br />
<strong>design</strong> <strong>elements</strong> using local craftsmen. These<br />
can include pavement treatments, wrought<br />
iron creations, fountain <strong>elements</strong>, landforms,<br />
lighting displays, stonework, and detailed<br />
carpentry.<br />
Applicability<br />
From a cultural perspective, the most<br />
signifi cant event in the <strong>District</strong>’s history<br />
is the batt le of <strong>San</strong> <strong>Jacinto</strong> that created the<br />
Republic of <strong>Texas</strong> and eventually led to the<br />
150 │ APPENDICES<br />
annexation of <strong>Texas</strong> by the United States. The<br />
district also has a strong industrial legacy as<br />
a major shipping port and petrochemical<br />
center. The region’s natural history is also<br />
signifi cant with its unique mix of coastal<br />
tallgrass prairie, mixed hardwood forest, and<br />
estuarine bayous. Art installations and work<br />
by local craftsmen should draw upon these<br />
primary themes in order to distinguish the<br />
unique qualities of the <strong>District</strong>.<br />

Design & Maintenance Considerations<br />
■<br />
■<br />
■<br />
■<br />
■<br />
■<br />
Space should be made available in new<br />
streetscape <strong>design</strong>s to accommodate<br />
future art installations.<br />
Installations can be coordinated with<br />
existing local art initiatives to leverage<br />
their impact.<br />
Work in a public right-of-way or on public<br />
land is subject to conditions set forth by<br />
local, state, and federal requirements. A<br />
permit for erecting a piece of art or <strong>design</strong><br />
element may be required.<br />
Art installations should elevate the<br />
awareness of visitors to the unique<br />
qualities of the <strong>District</strong> and to current<br />
cultural issues.<br />
Installations that intentionally off end or<br />
are obscene should be avoided and may<br />
be prohibited under local, or state laws.<br />
Permanent installations should be<br />
constructed of lasting materials that can<br />
withstand abuse.<br />
■<br />
■<br />
■<br />
■<br />
Temporary installations should have a<br />
fund available to cover the cost of their<br />
removal.<br />
Art installations should be identifi ed by<br />
signage that includes the name of the<br />
installation, the date erected, and the<br />
artist’s name.<br />
Installations should not impede pedestrian<br />
or vehicular traffi c.<br />
Install art in public view, such as schools,<br />
colleges, public plazas, and other campustype<br />
environments.<br />
Cost Considerations<br />
■<br />
■<br />
The cost for an art installation or<br />
functional <strong>design</strong> element can vary greatly<br />
depending upon the nature of the work<br />
and the prominence of the artist.<br />
Local community groups and students<br />
are a great resource for low-cost art<br />
installations.<br />

APPENDIX B - NATURAL HISTORY<br />
Appendix B presents a summary description of the vegetation of the coastal prairie province of the <strong>San</strong><br />
<strong>Jacinto</strong> River, as well as lists of native species and horticultural species, the latter being those that can<br />
thrive in local climatic conditions and do not spread invasively.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 153
VEGETATION OF THE COASTAL PRAIRIE PROVINCE OF THE SAN JACINTO RIVER<br />
At the time of European sett lement, the coastal province of the area<br />
between <strong>San</strong> <strong>Jacinto</strong> and the Gulf of Mexico was low, fl at, and everywhere<br />
vegetated by prairie. The water table was at or near the surface in most<br />
places, but in some areas, where the land undulated to form low mounds,<br />
there grew copses of open-grown trees, mostly oaks, a few pines. A<br />
few of the last remnants of this coastal vegetation is still extant at the<br />
Armand Bayou Nature Center, in Pasadena, <strong>Texas</strong>. For the thousands<br />
of years prior to Western sett lement, this vegetation was sustained at a<br />
fecund, maximum biodiversity by occasional grazing and regular fi res set<br />
by the native peoples. Overgrazing, fi re suppression, and various forms<br />
of development have all but obliterated the once beautiful and unique<br />
landscape of this area. Although there is some burning at the Armand<br />
Bayou preserve, if it’s combustible tracts were burned annually, it would<br />
represent the <strong>San</strong> <strong>Jacinto</strong> area as among the more fecund, unique, and<br />
beautiful landscapes of the coastal plain of the Gulf of Mexico.<br />
The verges with the estuaries along the <strong>San</strong> <strong>Jacinto</strong> and smaller drainages<br />
were treeless marshes, infi nitely enervated by shallow, narrow, estuarine<br />
channels. Those wetlands most dramatically infl uenced by salt-water<br />
tides are characterized by fringes or fl ats of Smooth Cordgrass (Spartina<br />
alternifl ora) and or Black Rush (Juncus roemerianus). Tule (Typha domingensis)<br />
is the common catt ail. On the more subtle rises more under the infl uence<br />
of fresh water fl owages from the hinterland are formed brackish marshes<br />
and wet meadows of Marsh-hay Cordgrass (Spartina patens), along with<br />
scatt erings of grasses and rushes such as Saltgrass (Distichlis spicata),<br />
Sea Club Rush (Bulboschoenus robustus), Sword Grass (Schoenoplectus<br />
americanus), California Bulrush (Schoenoplectus californicus), Needlerush<br />
(Juncus eff usus) and Seashore Paspalum (Paspalum vaginatum). Such<br />
marshes are punctuated with the yellow fl owers of the low subshrub, Sea<br />
Oxeye Daisy (Borrichia frutescens) or the purple-fl owerd Seaside Gerardia<br />
(Agalinis maritima). Gulf cordgrass (Spartina spartinae) is also widespread<br />
in the coastal prairies, most usually situated on the interfaces between the<br />
marshes and the low rises. Typical of the area is the shrub or small tree,<br />
Sea Myrtle (Baccharis halimifolia) and the bushy perennial Marsh Elder (Iva<br />
frutescens). The tidal fl ats are characterized by curious succulents such<br />
as the glassworts (Salicornia bigeelovii and Salicornia virginica), along with<br />
Vidrillos (Batis maritima).<br />
154 │ APPENDICES<br />
These watery sloughs were the spawning areas of the countless millions<br />
of fi sh that inhabited the western districts of the Gulf of Mexico. The<br />
marshes, prairies, and oak groves were the much sought-after growingseason<br />
homes of countless birds, many of whom had wintered in the<br />
Yucatan and other subequatorial districts.<br />
Most of the province was overlain by prairies dominated by warm-season<br />
grasses and wildfl owers, which passed gradually into the estuarine<br />
marshes. Wildfl owers and perennial grasses and sedges of the area were<br />
numerous and profuse throughout the prairies. In those areas that received<br />
regular fi re along with light grazing there were as many as twenty or more<br />
diff erent fl owering species in just a few square feet of area---each such<br />
small area unique in composition even from those nearby. The beauty of<br />
the warp and weft of life was indescribable. Many of these fl owering plants<br />
are of ornamental quality and a few are available in local nurseries. The<br />
U. S. Fish and Wildlife Service and U. S. Geological Survey have described<br />
these coastal prairies most beautifully in an article entitled, Paraise Lost.<br />
[htt p://library.fws.gov/pubs/paradise_lost.pdf]<br />
ECOLOGICAL RESTORATION<br />
<strong>Historic</strong>ally, there were probably 700-800 vascular plant species native to<br />
the <strong>San</strong> <strong>Jacinto</strong> area. If an ecological restoration were to be att empted as<br />
a landscape feature, it is from among these species that the restoration<br />
should consist. Most will not be available in the nursery trade, so the seed<br />
will have to be secured from the few local remnants, in consilience with a<br />
seed-collecting protocol as presented by the sponsor of the remnant. Most<br />
perennial beds have plants in drifts on 12-24” centers. Most of the native<br />
perennials are interdependent on from 10-30 diff erent species per quartermeter<br />
square, along with an array of insects and soil fungi. Consequently,<br />
many of these species will not last even fi ve years as perennial plantings in<br />
urban and suburban contexts. Insofar as management and maintenance is<br />
concerned, there can be no successful natural restoration without the use<br />
of regular applied landscape fi res.

The fl ora and fauna of the <strong>San</strong> <strong>Jacinto</strong> are among the more beautiful and<br />
singular as in any province anywhere in the world. The extent to which<br />
the architecture, infrastructural approaches, and landscape contexts<br />
support the integration of <strong>San</strong> <strong>Jacinto</strong>’s aboriginal assets and cultural<br />
history involve in our made or contrived landscape programs is the extent<br />
to which the area will be seen as unlike anywhere else on earth---truly<br />
special with its endowed gifts. As with architecture, the extent to which<br />
our choices include the hum-drum default plantings and commondityscale<br />
maintenance so ubiquitous across the southern United States is<br />
the extent to which <strong>San</strong> <strong>Jacinto</strong> will be in competition with other areas<br />
across the country that have made similar expedient choices, its identity<br />
sublimated to render it invisible.<br />
HORTICULTURAL PLANTS NATIVE TO SAN JACINTO<br />
With respect to the inclusion of trees in landscape plantings, a number of<br />
those native to the <strong>San</strong> <strong>Jacinto</strong> area are suitable as street trees, parkway<br />
trees, or trees in parking lots, provided there is enough room suffi cient<br />
square-footage of soil for lateral root growth and they are planted in<br />
contexts that will be out of the way of trampling. Larger trees will require<br />
a substantially greater unpaved, uncompacted, well-stewarded soil than<br />
would smaller trees.<br />
From among the canopy trees, perhaps the ten more evocative of <strong>San</strong><br />
<strong>Jacinto</strong>, tolerant of a variety of conditions, and relatively free of common<br />
diseases are Carya illinoensis, Juglans nigra, Magnolia grandifl ora, Pinus<br />
taeda, Quercus alba, Quercus lyrata, Quercus macrocarpa, Quercus michauxii,<br />
Quercus shumardii, and Taxodium distichum.<br />
160 │ APPENDICES<br />
One might consider the top ten smaller trees of <strong>San</strong> <strong>Jacinto</strong> to include Betula<br />
nigra, Chionanthus virginicus, Cornus fl orida, Crataegus marshallii, Ehretia<br />
anacua, Ilex opaca, Persea borbonia, Sapindus saponaria, Sassafras albidum, and<br />
Vaccinium arboreum.<br />
HORTICULTURAL PLANTS NATIVE TO TEXAS, BUT NOT SAN JACINTO<br />
The nearby city of Houston considers a number of <strong>Texas</strong> canopy trees<br />
as suitable for planting locally along parkways and in parking lots. A<br />
preponderance of their use can evoke <strong>Texas</strong>, but will dampen the<br />
opportunity to enhance and celebrate the uniqueness of <strong>San</strong> <strong>Jacinto</strong>.<br />

include the following. In some cases, these species are more suited to<br />
cultivation in harsh or casually <strong>design</strong>ed and maintained contexts, which<br />
also means that such areas will hardly be evocative of or emblematic of<br />
<strong>San</strong> <strong>Jacinto</strong>, more evocative of a value system that places litt le interest on<br />

The turf grasses, Bermuda Grass (Cynodon dactylon) and Bahia (Paspalum<br />
notatum) do not require anywhere near so much water as St. Augustine<br />
Grass (Stenotaphrum secundatum), and are more able to sustain a traditional<br />
weft than Zoysia (Zoysia japonica). For a litt le fuller, less mowed look in<br />
semi-shade, Sheep’s Fescue (Festuca ovina) is available. In areas with full<br />
sun and dry soil, Buff alo Grass (Buchloe dactyloides) can be nursed into a<br />
fi ne full weft that requires no irrigation; it is native to <strong>Texas</strong>, and possibly<br />
grew in the <strong>San</strong> <strong>Jacinto</strong> area at one time.<br />
The southern tip of <strong>Texas</strong>, near the mouth of the Rio Grande could be<br />
construed as subtropical insofar as plant hardiness. <strong>San</strong> <strong>Jacinto</strong> is<br />
unambiguously situated in the northern districts of Zone 9, which can<br />
be characterized as humid-south temperate. If, however, there is an<br />
interest to create a tropical sett ing with trees, but litt le interest in winter<br />
greenhouse storage and heavy watering, there are a few trees that can give<br />
the impression of the topics, at least in the minds of those who have never<br />
been there. Perhaps the more evocative of such trees hardy in the <strong>San</strong><br />
<strong>Jacinto</strong> province are characterized by the palms and fl owering trees with<br />
broad, evergreen leaves or fern-like leaves with showy fl owers. With lots<br />
of room for argument, a “top 10” list might include the following: Pindo<br />
Palm (Butia capitata), Mexican Olive (Cordia boissieri), Southern Magnolia<br />
(Magnolia grandifl ora), Avacado Tree (Persea americana), Mexican Palm<br />
(Sabal mexicana), <strong>Texas</strong> Palm (Sabal texana), African Tuliptree (Spathodia<br />
campanulata), Queen Palm (Syagrus romanzoffi ana), and Tamarind<br />
(Tamarindus indica).<br />

SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 169
APPENDIX D - TEXAS TOOLBOX<br />
Appendix D presents economic development tools for <strong>Texas</strong> communities. Assembled by Knudson, LP.<br />
Due to the sheer magnitude of the 280,000 acre <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong><br />
<strong>District</strong>, one size cannot fi t all when it comes to implementating these<br />
standards. It is critical that each community and organization undertaking<br />
projects identify implementation tools that will best work with community<br />
policies and that can leverage tax dollars and funding from other sources.<br />
Proactive roles in adopting an economic development plan may include<br />
the use of current enabling legislation that allows the county and cities to<br />
use the tools presented here individually or, in the event that one tool is<br />
insuffi cient to carry out the expectations of the public, in combination.<br />
Economic incentives can be off ered to help fund private sector<br />
development while helping to achieve the public vision. These ‘publicprivate<br />
partnerships’ should include transparency in sharing development<br />
proforma and budgets with all parties. Other partnerships include<br />
public to public partnerships, county to city partnerships, Economic<br />
Development Corporation to city partnerships, as well as other agency<br />
public to public partnerships that can strengthen initiatives, reduce<br />
risk, and help implement a common vision.<br />
A wide range of tools and economic incentives provide opportunities<br />
that can create fi nancing for beautifi cation and revitalization. However,<br />
implementors should always consider the market forces critical to any<br />
redevelopment strategy, as these incentives are meant to supplement<br />
local funding and fi nancing.<br />
SAN JACINTO TEXAS HISTORIC DISTRICT CORRIDOR STANDARDS │ 171
Tools to consider for the <strong>San</strong> <strong>Jacinto</strong> <strong>Texas</strong> <strong>Historic</strong> <strong>District</strong> include:<br />
4A Sales Tax: cities located in a county with a population of less than<br />
500,000 may impose the 4A sales tax if the new combined local sales tax<br />
rate would not exceed 2 percent. Some cities located in Harris County may<br />
also use 4A for economic development eff orts, but eligibility varies from<br />
county to county. For information on eligible cities call the Comptroller’s<br />
Local Government Assistance section (800.531.5441 ext 3-4679.)<br />
4B Sales Tax: 4B sales tax requires an election and can be created in ¼<br />
cent increments up to ½ cent. This tool can be used to leverage municipal<br />
bond fi nancing. Cities are eligible to adopt the 4B sales tax if the combined<br />
local sales tax rate would not exceed 2 percent.<br />
Neighborhood Empowerment Zone: this overlay zone allows cities to<br />
provide incentives for property improvements aligned with the objectives<br />
of an approved Plan. This 10-year zone can be structured to reimburse<br />
property owners through revenues generated by sales, real property, and<br />
personal property tax revenues. For example if a business implements a<br />
$100,000 façade/parking lot improvement, the city can reimburse all or a<br />
part of that investment for a period of 10 years from taxes generated from<br />
that property.<br />
Tax Increment Reinvestment Zone: this <strong>design</strong>ation provides incentives<br />
to property owners making investments and improvements and is<br />
reimbursed through sales and real property taxes. Most TIRZs are<br />
structured for 20 year or longer. This tool would be more useful if it<br />
covered a larger geographical area, as it could take as long as 20 to 30<br />
years to fi nance improvements such as relocating/burying overheard<br />
power lines or making major infrastructure enhancements.<br />
172 │ APPENDICES<br />
Chapter 380/381 Development Agreements: this project specifi c tool is a<br />
contract between a developer and the city or county that is structured like a<br />
TIRZ but can also include other concessions such as gifts of right-of-way.<br />
Management <strong>District</strong>s: this tool works well for multiple property owners<br />
seeking project funding for improvements, maintenance, management,<br />
promotions, and capital costs. It is an overlapping tax or assessment<br />
depending on how it is structured. While the enabling legislation provides for<br />
creation through the TCEQ, most Management <strong>District</strong>s are created by special<br />
legislation, which allows cities to specify <strong>District</strong> powers.<br />
Community Development Block Grants (CDBG): these grants fund local<br />
community development activities such as aff ordable housing, anti-poverty<br />
programs, and infrastructure development. CDBG, like other block grant<br />
programs, diff er from categorical grants in that they are subject to less federal<br />
oversight and are largely used at the discretion of state and local governments<br />
and their grantees.<br />
Hotel Occupancy Taxes: tax imposed on a hotel room or space costing $15 or<br />
more per night. Local hotel taxes apply to sleeping rooms costing $2 or more<br />
each day.
