Meeting Minutes

February 10, 2026

and Jefferson Ave., Property ID: 52779, (ZC 03-26)
Kyle Warren, Planner, presented the staff report. He stated that the case was
postponed from January’s Planning and Zoning Commission meeting and advised that
he would be brief with the presentation.
Mr. Warren stated the 15.005-acre tract of land is located near the intersection of
Jefferson Ave and SH 46 zoned both Commercial and Single-Family Residential. The
request is for Multifamily-3, High Density Multifamily for the entire 15 acres. He
reminded the Commission that the maximum allowable number of units in the zoning
district was 20, and that the applicant said they were only going to have 17 units per
acre.
Mr. Warren reminded the Commission that the proposed use was inconsistent with
both the FLUPs. Traditional Residential by maximum units allowed (20) and
Commercial Corridor because Multifamily needs to be by two arterial street. He noted
that the University Center FLUP was adjacent to the property, across Jefferson Avenue
which is supportive of Multifamily High-Density zoning.
Mr. Warren stated that if the apartments were developed, the property would have a
double-sided planting buffer of 30 feet for a three-story complex, against the
single-family zoned properties to the east and south.
He stated that two additional letters were received, one in favor with nothing noted and
one in opposition stating concerns of increase in crime and congestion. The previous
two letters of opposition touched on potential drainage issues a new development could
bring to the area.
The regular meeting recessed, and a public hearing was held. Kalie Gast, and attorney
Rob Killen of Killen, Griffin & Farrimond, LLC gave a presentation of the zone change
request. Mr. Killen presented his power point touching on traffic impact, site analysis,
walk ability, potential community and economic benefits, a City Grant for sidewalk
infrastructure, and renderings of the project. Mr. Killen also proposed that a deed
restriction would be created to put a density cap of 17 units per acre and would be
recorded prior to the first city council meeting of March if the zoning change were
approved.
Kalie Gast answered questions from the Commission on market studies for the project
concerning demand, growth patterns, and income levels. She said 255 units were
being proposed for working/middle class income levels.
Carlos Moreno, Habitat for Humanity spoke on the case, asking for support of the
project as it was Habitat’s land that was in question for the zone change. He said The
Kittle Group aligned with their outlook of trying to provide affordable housing for
Seguin.
Elizabeth McCowan, Habitat for Humanity also came forward in support of the zoning
change as it would allow Habitat to fulfill their mission and vision.
Madeline Zwicke, Habitat for Humanity approached the Commission. Chair Patrick
Felty asked her how this large multifamily development would affect the ability to build
single family homes on the remaining 15 acres to the south.
Michael Taylor, Habitat for Humanity, addressed questions from the Commission. He
said the mix of affordable single-family homes as well as work force apartment housing

would certainly benefit Habitats goals for Seguin. He also stated that Habitat’s ability
to develop the site without the sale of the 15 acres in question would be very limited.
He said the remaining 15 acres would be reserved for 4 acres of retail commercial and
11 acres of single-family zoning.
There being no additional responses from the public the regular meeting reconvened
for action.
Chair Felty asked staff if the grant for sidewalks was on Ermel Street or SH 46.
Jennifer Shortess, Assistant City Engineer, stated the grant is a safe route to school
grant through TxDOT and the Alamo area MPO and is a concrete trail from B&B road
to Kingsbury Street along SH 46. She then stated it would be in construction from
2029-2031.
A motion was made by Vice Chair Davila, seconded by Commissioner Silvius,
that the Zoning Change to Multi-Family High Density 3 (MF-3) be recommended
for approval. The motion carried by the following vote:

SUMMARY OF STAFF ANALYSIS & RECOMMENDATION:
The applicant is requesting a Specific Use Permit (SUP) to allow for residential use in
Commercial (C) zoning. The existing residential home dates back as far as 1950 and has
always been utilized in a residential manner. The property has been without utilities since
April 4th 2022, resulting in a loss of the structure’s legal nonconforming use as a residence.
The applicant is requesting a Specific Use Permit to allow for the continuation of the site’s
past residential use.
Staff is recommending approval of the Specific Use Permit with the following conditions:
•
•
•
•

Residential standards seen in the City’s Unified Development Code (UDC) will apply
to the property.
Site can be used for residential use only.
If property is sold, SUP will transfer to new owner if use remains residential.
This SUP will be voided if the site is vacant or without utilities for 6 months.

PLANNING DEPARTMENT ANALYSIS
SITE DESCRIPTION:
The site is one (1) legal lot totaling 1.094 ac and contains two (2) residential homes (831 & 817 W. Court St). The existing
residential homes on the property date back to the 1950’s and have been utilized for residential use. The structure at
831 W. Court St. is an active residential home on this lot. Utility service to 817 W. Court St. was disconnected April 4,
2022 and has been off since.

CODE REQUIREMENTS:
Section 3.4.3 Land Use Matrix of the city of Seguin’s Unified Development Code (UDC), allows for an existing singlefamily dwelling within Commercial (C) zoning to be utilized for residential use with the approval of a Specific Use
Permit (SUP). The existing structure at 817 W. Court St. has been vacant and without utilities for more than 6 months
and it has lost its legal nonconformity status. A Specific Use Permit (SUP) will be required to allow for the existing
residential home to be utilized as a residence again.

COMPATIBILITY WITH SURROUNDING LAND USE & ZONING:
The site is located with an area mostly comprised of Commercial zoning and use, with some residential uses within
Commercial zoning that was existing prior to the city adopting zoning in 1989. The property to the east is zoned
commercial containing an unoccupied building, to the west, Commercial (C) zoning is utilized for residential use. To the
south is residential zoning and use, and a car lot zoned Commercial (C) to the north.
COMPREHENSIVE PLAN:
The Comprehensive Plan proposed to have development located on arterial roadways connecting Seguin to
surrounding towns and metropolitan areas. The property is in the Commercial zoning but the city’s FLUP has the
property under Traditional Residential.
The Traditional Residential classification encompasses the residential development surrounding Seguin’s Downtown
area with an eclectic character and neighborhood design that has evolved over the years. This area connects the more
traditional grid pattern of the Downtown area to a more curvilinear, suburban-style development with various homes
and lot sizes based on the era of construction. New residential development within this area should be evaluated siteby-site to prevent incompatible scaling and density.
Neighborhood-scaled commercial services should be located along the major thoroughfares to support a walkable,
mixed-use environment. High-density residential uses can be appropriate at the scale of neighboring developments,
and vacant tracts should utilize compatible design criteria with nearby buildings.

HEALTH, SAFETY, AND GENERAL WELFARE:
No health or safety issues have been identified.

STREET FRONTAGE & ACCESS:
The property contains an existing curb cut and driveway accessed from West Court St.

PLANNING & CODES

MEMORANDUM
To:

Seguin Planning & Zoning Commission

From: Pamela Centeno, Director of Planning & Codes
Subject:

Amendments to Section 3.4.3 Land Use Matrix- Industrial Uses and to
Chapter 7- Definitions, to add and define a data center as a new use

Date:

March 2, 2026

The number of data centers being constructed in Texas is rapidly increasing as companies
pursue sites in cities and counties across the state. Unlike counties, Texas cities have the
authority to adopt zoning regulations to promote the public health, safety, morals, and
general welfare of their communities. While data centers are vital to today’s digital economy,
careful consideration must be given to where they are permitted within city limits. To help
ensure that such facilities are developed in appropriate locations and that adequate
safeguards are in place to protect surrounding properties, the Seguin Planning Department
is proposing to amend the Unified Development Code (UDC) to add data centers as an
industrial use in the Land Use Matrix with a requirement for a Specific Use Permit. Staff is
also proposing to add a definition for a data center to the UDC. The proposed amendments
to Section 3.4.3 and to Chapter 7- definitions, are as follows:

PLANNING & CODES

MEMORANDUM
To:

Seguin Planning & Zoning Commission

From:

Shelly Jackson, Assistant Director of Planning & Codes

Subject:

Unified Development Code (UDC) amendments to modify Section 1.2.7.C
Floodplain Administrator, Section 1.4 Expiration of Applications,
Section 2.10 Flood Plain Development Permit, Section 4.6 Stormwater
and Drainage Standards, and Section 4.3.2 Drainage Easement (DE)

Date:

March 2, 2026

The Planning Department is proposing amendments to modify Section 1.2.7.C
(Floodplain Administrator), Section 1.4 (Expiration of Applications), Section 2.10 (Flood
Plain Development Permit), Section 4.6 (Stormwater and Drainage Standards), and
Section 4.3.2 (Drainage Easement (DE)) of the UDC. The proposed changes are as follows:
•
•

•
•

•

Section 1.2.7.C: Update the responsibilities of the Floodplain Administrator to
align with recent amendments to Flood Damage Prevention Ordinance #24-098.
Section 1.4: Add a “Flood Zone Map Change” permit to the list of applications
required in the UDC. This permit allows applicants to request a revision or
amendment to the Flood Insurance Rate Map (FIRM) administered by FEMA to
reflect updated floodplain information or correct flood zone determinations for a
property.
Section 2.10: Update permit standards for a Floodplain Development Permit to
clarify application requirements and ensure consistency with the Flood Damage
Prevention Ordinance.
Sec. 4.3.2 and 4.6.5: To provide consistency between the UDC and the Stormwater
Criteria Manual, revision to UDC Sec. 4.3.2 and 4.6.5 are required. In areas with
floodplain, the subdivider or developer shall designate a drainage easement for the
floodway. Additionally, UDC Sec. 4.6.5 requires revision in that waiver requests or
variances for floodplain are considered by the appeal board as established by the
City, consistent with Code of Ordinance Sec. 54-41.
Sec. 4.6.1: Based on review of the Stormwater Criteria Manual during the Drainage
Master Plan project, further details were added to clarify the zone of influence (or
downstream study point) for stormwater management plans. Calculations to verify
downstream adequacy shall be performed according to the Stormwater Criteria
Manual.

Attached is a copy of the proposed UDC amendments to Sections mentioned above.

Proposed Amendments to Section 1.2.7.C Floodplain Administrator, Section1.4
Expiration of Applications, Section 2.10 Flood Plain Development Permit, Section 4.6
Stormwater and Drainage Standards, and Section 4.3.2 Drainage Easement (DE)
1.2.7.C Floodplain Administrator
The Floodplain Administrator or his/her designee shall administer and implement the
provisions of this article and other appropriate sections of 44 CFR (Emergency Management
and Assistance-National Flood Insurance Program Regulations) pertaining to floodplain
management. Duties and responsibilities of the floodplain administrator shall include, but
not be limited to, the following:
• Maintain and hold open for public inspection all records pertaining to the provisions
of this article.
• Review permit application to determine whether proposed building sites, including
the placement of manufactured homes, will be reasonably safe from flooding.
• Review, approve or deny all applications for floodplain development permits.
• Review permits for proposed development to assure that all necessary permits have
been obtained from those federal, state or local governmental agencies (including
section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33
U.S.C. 1334) from which prior approval is required.
• Where interpretation is needed as to the exact location of the boundaries of the areas
of special flood hazards (for example, where there appears to be a conflict between
a mapped boundary and actual field conditions) the floodplain administrator shall
make the necessary interpretation.
• Notify, in riverine situations, adjacent communities and the state coordinating
agency which is the Texas Water Development Board (TWDB) and also the Texas
Commission of Environmental Quality (TCEQ) prior to any alteration or relocation of
a watercourse, and submit evidence of such notification to the Federal Emergency
Management Agency (FEMA).
• Assure that the flood-carrying capacity within the altered or relocated portion of any
watercourse is maintained.
• When base flood elevation data has not been provided in accordance with Division II,
the floodplain administrator shall require the owner of the property, or their
representative, to perform the necessary hydraulic studies to determine the one (1)
percent annual chance (100-year) floodplain, base flood elevation and floodway to
obtain a letter of map revision from FEMA.
• The floodplain administrator may obtain, review, and reasonably utilize any base
flood, elevation data, hydrology, and floodway data available from a federal, state, or
other source, in order to administer the provisions of Chapter 54, Article II (Flood
Damage Prevention) of the City of Seguin Code of Ordinances.
• When regulatory floodway has not been designated, the floodplain administrator
must require that no new construction, substantial improvements, or other
development (including fill) shall be permitted within zones A1-30 and AE on the
community’s FIRM, unless it is demonstrated that the cumulative effect of the

13

•

proposed development, when combined elevation of the base flood more than one
0.04 foot at any time within the community.
Under the provisions of 44 CFR Chapter 1, Section 65.12 of the National Flood
Insurance Program regulations, a community may approve certain developments in
zones A1-30, AE, AH, on the community’s FIRM which increased the water surface
elevation of the base flood by more than one 0.04 foot, provided that the community
first completes all of the provisions required by Section 65.12.
When floodproofing is utilized for a particular structure, obtain certifications from a
registered professional engineer or architect in accordance with FEMA floodproofing
guidelines.
Make on-site inspections of work in progress. As the work pursuant to a floodplain
development permit progress, the Floodplain Administrator shall make as many
inspections of the work as may be necessary to ensure that the work is being done
according to the provisions of the local ordinance and the terms of the permit. In
exercising this power, the Floodplain Administrator has the right, upon presentation
of proper credentials, to enter on any premises within the jurisdiction of the
community at any reasonable hour for the purposes of inspection or other
enforcement action.
Issue stop-work orders as required. Whenever a building or part thereof is being
constructed, reconstructed, altered, or repaired in violation of this Ordinance, the
Floodplain Administrator may order the work to be immediately stopped. The stopwork order shall be in writing and directed at the person doing or in charge of the
work.
Revoke floodplain development permits as required. The Floodplain Administrator
may revoke and require the return of the floodplain development permit by notifying
the permit holder in writing stating the reason(s) for revocation. Permits shall be
revoked for any substantial departure from the approved application, plans, and
specifications; for refusal or failure to comply with the requirements of State or local
laws; or for false statements or misrepresentations made in securing the permit. Any
floodplain development permit mistakenly issued in violation of an applicable State
or local law may also be revoked.
Review, provide input, and make recommendations for variance requests.
Maintain a current map repository to include, but not limited to, the FIS Report, FIRM
and other official flood maps and studies adopted.

2.10 Flood Plain Floodplain Development Permit
2.10.3 Applicability
A floodplain development permit applies to all areas of special flood hazard within the
jurisdiction of the City of Seguin, Texas. No structure or land shall be located, altered, or have
its use changed without approval of a flood plain floodplain development permit.
2.10.4 Criteria for Approval and Process
Floodplain development permit standards are detailed in Chapter 4. Application for a
floodplain development permit shall be presented to the Floodplain Administrator.
Application materials should include but not be limited to, plans in duplicate drawn to scale
showing the location, dimensions, and elevation of proposed landscape alterations, existing
and proposed structures, including the placement of manufactured homes, and the location
of the foregoing in relation to areas of special flood hazard. For all proposed subdivision
developments within, abutting, or adjacent to a floodplain, a Flood Study is required per the
Stormwater Criteria Manual and shall be approved by the City Engineer prior to approval of
the floodplain development permit. Additionally, the following information is required:

4.3 Easements
4.3.2 Drainage Easement (DE)
Where conditions require, there shall be provided an adequate stormwater drainage
easement, as required by the Stormwater Criteria Manual. In areas where there is an
approved and/or mapped floodplain, the subdivider or developer shall designate a drainage
easement(s) for the floodplain floodway. Where such easement is adjacent to lots, tracts,
or reserves, the easement shall be noted on the final plat as follows: "The easement
indicated shall be kept clear of fences, buildings, planting, and other obstructions to the
operation and maintenance of the drainage facility, and abutting property shall not be
permitted to drain into this easement except by approved means." For one- and two-family

17

residential subdivisions, drainage easements crossing lots and property lines are prohibited.
Drainage easement shall be placed on separate common area lots, as stipulated in the
Stormwater Criteria Manual.
Section 4.6 Stormwater and Drainage Standards
4.6.1 General Requirements
All proposed developments shall provide for new drainage facilities, the improvement of
existing drainage facilities, channel improvements, grading, driveway adjustments, culvert
improvements or other drainage improvements determined by the City Engineer to provide
for the stormwater drainage needs of the development and the downstream areas, designed
and constructed in accordance with the requirements specified in the Stormwater Criteria
Manual. The developer shall provide all necessary information and calculations to the City
Engineer to demonstrate that the proposed development does not exceed the capacities of
the stormwater management systems as a result of the development. If any appreciable
adverse impacts still exist at a distance of 2,000 feet at the zone of influence downstream of
the proposed development, the City Engineer may require the construction of additional
drainage facilities until any remaining adverse impacts are deemed de minimis (at no cost to
the City). It is the responsibility of the developer to provide for conveyance of off-site storm
water. The developer's design package submitted to the City shall include a description of
all potential off-site impacts caused by the development and the proposed mitigation
procedures for the impacts, including but not limited to:
-

-

Alteration of existing upstream drainage areas and/or conveyance systems due to the
proposed development.
The detention facility discharge shall be located to provide the least impact on
downstream conditions, including requirements for the discharge to be routed to
street curbs, bar ditches, storm sewer or other drainage way.
The impact of flow concentration from the detention facility discharge point on
existing drainage areas and/or conveyance systems.
Extension of existing conveyance systems through the development.
The altering of existing on-site conveyance systems.

In order to mitigate the impact of the proposed development, the phasing of development,
the use of off-site control methods or the construction of off-site drainage improvements
may be necessary. Calculations to verify downstream adequacy shall be performed to the
nearest receiving waterway(s) according to the Stormwater Criteria Manual. Should
projected stormwater runoff from the proposed development exceed the capacity of the
existing drainage facilities and/or natural channels, the developer shall be responsible for
improving the existing facilities at its own cost.

4.6.5 Floodplain.
When a proposed subdivision or development has within it a drainageway where no
regulatory floodway has been designated and is located within a FEMA mapped floodplain,
no new construction, substantial improvement or other development, including fill, shall be
permitted in an area that may have flood hazards, unless it is demonstrated that the
cumulative effect of the proposed development or improvements, when combined with all
other existing and anticipated development and improvements will not substantially
increase the water surface elevation. In areas where there is an approved and/or mapped
floodway floodplain, the subdivider or developer shall designate a drainage easement(s) for
the floodway. In areas where a floodway is mapped and approved by the city, a flood study
or demonstration of “no flood height increase” shall be required. If a proposed subdivision
is within an area where flooding may occur, where there is no floodplain shown on a cityapproved floodplain map, or where there is located an approved floodplain but not floodway,
the subdivider shall:
-

-

-

Conduct a study of where the base flood elevation would be, assuming a fully
developed watershed, show a drainage easement on the plat, and show the elevation
of the floodplain at intervals of every 500 lineal feet, designate the area equivalent to
the floodway to be a drainage easement; or
Conduct a study, using HEC or similar modeling that is approved by the city engineer,
to ensure that the proposed development would not increase the elevation of the one
percent annual chance base flood and the area equivalent to the floodway will be
designated as a drainage easement; or
Request a variance from the above requirements, The request for the variance shall
be assessed with respect to proposed density, land use, lot sizes, building sizes,
anticipated impervious cover, and the width and depth of the existing floodplain. all
wavier requests shall be considered and decided by the Planning Commission. the
appeal board as established by the City.
