to Engineers' Seals). The site development plan must contain all of
the following information.
(1) Title page. A title page shall show the name of
the project, the county (and city if applicable) in which the proposed
project is located, the name of the applicant, the name of the engineer,

(3) Engineer's appointment. The site development plan
shall contain an engineer's appointment, which consists of a letter
from the applicant to the executive director identifying the consulting
engineering firm responsible for the submission of the plan, specifications,
and any other technical data to be evaluated by the commission regarding
the project.
(4) Land use. To assist the executive director in evaluating
the impact of the facility on the surrounding area, the applicant
shall provide the following:

within one mile of the facility. If the facility requires approval
as a nonconforming use or a special use permit from the local government
having jurisdiction, a copy of such approval shall be submitted with
the application;
(B) a description of the character of the surrounding
land uses within one mile of the proposed facility;
(C) proximity to residences and other uses (e.g., schools,
churches, cemeteries, historic structures, historic sites, archaeologically
significant sites, sites having exceptional aesthetic quality, parks,
recreational sites, recreational facilities, licensed day care centers,
etc.). Give the approximate number of residences and business establishments
within one mile of the proposed facility including the distances and
directions to the nearest residences and businesses;
(D) a discussion that shows the facility is compatible
with the surrounding land uses; and
(E) a constructed land use map showing the land use,
zoning, residences, businesses, schools, churches, cemeteries, historic
structures, historic sites, archaeologically significant sites, sites
having exceptional aesthetic quality, licensed day care centers, parks,
recreational sites and recreational facilities within one mile of
the facility, and wells within 500 feet of the facility.
(5) Access. To assist the executive director in evaluating
the impact of the facility on the surrounding roadway system, the
applicant shall provide the following:
(A) data on the roadways within one mile of the facility
used to access the facility. The data shall include dimensions, surfacing,
general condition, capacity, and load limits;
(B) data on the volume of vehicular traffic on access
roads within one mile of the proposed facility. The applicant shall
include both existing and projected traffic during the life of the
facility (for projected include both traffic generated by the facility
and anticipated increase without the facility);
(C) an analysis of the impact the facility will have
on the area roadway system, including a discussion on any mitigating
measures (turning lanes, roadway improvements, intersection improvements,
etc.) proposed with the project; and
(D) an access roadway map showing all area roadways
within a mile of the facility. The data and analysis required in subparagraphs
(A) - (C) of this paragraph shall be keyed to this map.
(6) Facility development. To assist the executive director
in evaluating the impact of the facility on the environment, the applicant
shall provide the following.
(A) Surface water protection plan. The surface water
protection plan shall be prepared by a licensed professional engineer.
At a minimum, the applicant shall provide all of the following:
(i) a design for a run-on control system capable of
preventing flow onto the facility during the peak discharge from at
least a 25-year, 24-hour rainfall event;
(ii) a design for a runoff management system to collect
and control at least the peak discharge from the facility generated
by a 25-year, 24-hour rainfall event;
(iii) a design for a contaminated water collection
system to collect and contain all leachate. If the design uses leachate
for any processing, the applicant shall clearly demonstrate that such
use will not result in contamination of the final product; and
(iv) drainage calculations as follows.
(I) Calculations for areas of 200 acres or less shall
follow the rational method as specified in the Texas Department of
Transportation Bridge Division Hydraulic Manual.
(II) Calculations for discharges from areas greater
than 200 acres shall be computed by using United States Geological
Survey (USGS) hydraulic equations compiled by the USGS and the Texas
Department of Transportation Bridge Division Hydraulic Manual, the
HEC-1 and HEC-2 computer programs developed through the Hydrologic
Engineering Center of the United States Army Corps of Engineers, or
an equivalent or better method approved by the executive director.
(III) Calculations for sizing containment facilities
for leachate shall be determined by a mass balance based on the facility's
proposed leachate disposal method.
(IV) Temporary and permanent erosion control measures
shall be discussed;
(v) drainage maps and drainage plans shall be provided
as follows:
(I) an off-site topographic drainage map showing all
areas that contribute to the facility's run-on. The map shall delineate
the drainage basins and sub-basins, show the direction of flow, time
of concentration, basin area, rainfall intensity, and flow rate. This
map shall also show all creeks, rivers, intermittent streams, lakes,
bayous, bays, estuaries, arroyos, and other surface waters in the
state;
(II) a pre-construction on-site drainage map. The map
shall delineate the drainage basins and sub-basins, show the direction
of flow, time of concentration, basin area, rainfall intensity and
flow rate;
(III) a post-construction on-site drainage map. The
map shall delineate the drainage basins and sub-basins, show the direction
of flow, time of concentration, basin area, rainfall intensity, and
flow rate;
(IV) a drainage facilities map. The map shall show
all proposed drainage facilities (ditches, ponds, piping, inlets,
outfalls, structures, etc.) and design parameters (velocities, cross-section
areas, grades, flowline elevations, etc.). Complete cross-sections
of all ditches and ponds shall be included;
(V) a profile drawing. The drawing shall include profiles
of all ditches and pipes. Profiles shall include top of bank, flowline,
hydraulic grade, and existing groundline. Ditches and swells shall
have a minimum of one foot of freeboard;
(VI) a floodplain and wetlands map. The map shall show
the location and lateral extent of all floodplains and wetlands on
the site and on lands within 500 feet of the site; and
(VII) an erosion control map which indicates placement
of erosion control features on the site.
(B) Geologic/hydrogeologic report. The geologic/hydrogeologic
report shall be prepared by an engineer or qualified geologist/hydrogeologist.
The applicant shall include discussion and information on all of the
following:
(i) a description of the regional geology of the area.
This section shall include:
(I) a geologic map of the region with text describing
the stratigraphy and lithology of the map units. An appropriate section
of a published map series such as the Geologic Atlas of Texas prepared
by The University of Texas at Austin's Bureau of Economic Geology
is acceptable;
(II) a description of the generalized stratigraphic
column in the facility area from the base of the lowermost aquifer
capable of providing usable groundwater, or from a depth of 1,000
feet, whichever is less, to the land surface. The geologic age, lithology,
variation in lithology, thickness, depth geometry, hydraulic conductivity,
and depositional history of each geologic unit should be described
based upon available geologic information;
(ii) a description of the geologic processes active
in the vicinity of the facility. This description shall include an
identification of any faults and/or subsidence in the area of the
facility;
(iii) a description of the regional aquifers in the
vicinity of the facility based upon published and open-file sources.
