In accordance with the Texas State University Stormwater Management Program,
this document should serve as guidance for all landscape and irrigation practices
that take place within the campus. This document is applicable to any department
or contractor who may perform landscape/irrigation installation, management, or
repairs on Texas State University property. Areas covered by these standards
include but may not be limited to:
Campus grounds
Athletic fields
Intramural fields
Golf course
Freeman Ranch
Residence Hall landscapes
New construction/remodel for contracted landscape services
By providing a campus standard for all landscape and irrigation practices, the
University will remain in compliance with the Municipal Separate Storm Sewer
Systems (MS4) Permit.
SECTION 1 – INTRODUCTION
1
Irrigation
All departments are to adopt the following standards regarding landscape
irrigation.
a. Audit turf areas and replace sprinklers with “matched precipitation
rate” products (i.e. rotators or nozzles for rotary gear driven
sprinklers). Utilize campus staff or contractors as necessary.
b. Provide drip irrigation systems where appropriate in areas
recommended by the Licensed Landscape Irrigators.
c. Install central control (with flow control) and soil moisture sensors
for all fields and grounds.
d. As much as possible and feasible, follow drought restriction rules in
terms of hours during the day for irrigation (i.e. evening and night
time hours). Exceptions would include when trying to establish
overseed in the Fall and when auditing/maintaining systems (can’t be
done at night).
Landscape
Refrain from using fertilizers with “high” nitrogen leaching potential when
rain is forecasted. See products identified in red in Attachment 1.
Refrain from using pesticides listed in Attachment 2, all of which are
classified as “high,” “extreme,” or “super” toxicity for aquatics.
Always use shields or spray curtains when applying chemicals with sprayers.
SECTION 2 – CAMPUS STANDARDS
2
Use a standardized form to inventory stored materials (Attachment 3).
Use a standardized form to track the amount of fertilizer spread (Attachment 4).
Use the Standardized TAD Pesticide Applicator Record after applying pesticides (Attachment 5).
