“On Holiday (Girl resting on the grass)” | 1879 Kuznetsov Nikolai Dmitrievich

During office hours today we pull together the results of over ten years of tracking the best practice literature for management of an feature of educational settlements, in any season.  Grass and turf management on school and college campuses is crucial for several reasons:

  • It enhances aesthetic appeal, creating a welcoming and attractive environment for students, faculty, and visitors.
  • Well-maintained grounds support outdoor activities, sports, and events, promoting physical health and social interaction.
  • Proper management also ensures safety by reducing hazards such as uneven surfaces or overgrown areas.
  • Environmentally, it contributes to soil health, water management, and biodiversity.
  • Maintaining the allure of green spaces reflects the institution’s commitment to sustainability and pride in its facilities, positively influencing prospective students and community perception.


Several trade associations are involved in campus lawn care and exterior environment management. These organizations provide resources, education, and networking opportunities for professionals in the field. Key associations include:

Professional Grounds Management Society – Focuses on grounds management in various settings, including educational institutions.

Sports Turf Managers Association  – Dedicated to advancing the profession of sports field management.

National Association of Landscape Professionals  – Represents landscape professionals and offers resources for lawn care and landscaping.

International Society of Arboriculture  – Promotes the professional practice of arboriculture.  (An ANSI accredited standards developer)

Golf Course Superintendents Association of America  – Provides education and support for turf management professionals, including those managing campus golf courses.

American Society of Landscape Architects  – Supports landscape architecture professionals, including those involved in campus planning and design.

“Children in the Garden” 1892 Gładysław Podkowiński

The purpose of the American Standard for Nursery Stock — ANSI Z60.1 — is to provide buyers and sellers of nursery stock with a common terminology in order to facilitate transactions involving nursery stock.  This standards establishes common techniques for

(a) measuring plants,

(b) specifying and stating the size of plants,

(c) determining the proper relationship between height and caliper, or height and width, and

(d) determining whether a root ball or container is large enough for a particular size plant.

This document — prepared under a grant to ANSI by AmericanHort — is a communication tool for the exchanges of products and services but does not provide buyers with any assurance of the health or quality of the nursery stock being specified or sold.  It does not cover labor resources.

The 2014 revision should be entering another revision cycle though the pandemic has slowed standards setting among many non-profits.  We encourage front-line staff to participate directly in the American Hort standards setting enterprise.  CLICK HERE for contact information.

We sweep through the status of best practice literature for anything related to exterior assets in education communities during our Bucolia colloquium.   See our CALENDAR for the next online meeting; open to everyone.

“Landscape with a clump of trees” 1844 Théodore Rousseau

 

“Keep a green tree in your heart

and perhaps a singing bird will come”. 

— Chinese proverb

 

The condition of campus gardens, trees and landscaping is a central element of ambiance, brand identity, environmental instruction and even revenue to education communities when tied to charitable donations.   The Tree Care Industry Association (TCIA) is trade association of 2300 private tree care firms that is also an ANSI-accredited standards developer.  It has several titles relevant to education communities and posts drafts of best practice titles at the link below:

Current Projects & Public Review Periods

Last year we tracked a revision of TCIA A300 that asserted leading practice for lightning protection has been released for public consultation.   The consultation period closed and, like many standards setting organizations, leading practice discovery has been impeded by the circumstances of the pandemic.

We encourage our colleagues in business units responsible for lawns, trees, gardens and pathways to participate in the TCIA standards development process (Learn more HERE).  Stakeholders in any interest category may communicate directly with Amy Tetreault at the Tree Care Industry Association, (603) 314-5380, [email protected], 136 Harvey Rd # 101, Londonderry, NH 03053.

2023 National Electrical Code Article 490 Bibliography

Ahead of the April close date for comments on the Second Draft of the 2026 revision of the NEC we examine thought trends on the following:

  1. How does “high voltage” differ among electrotechnology professionals?  Signaling and control systems workers have a much lower criteria than a merchant utility lineman than a campus bulk distribution engineer.  In other words, “high voltage” is generally understood in practice and essential for worker safety.  Labeling counts.
  2. What is the origin of the apparent “confusion’ about high voltage in the IEEE, IEC, NFPA and TIA electrical safety catalogs?  Is the distinction functionally acceptable — i.e. a term of art understood well enough in practice?
  3. How can the 2026 NEC be improved for engineers, electricians and inspectors?  There has been some considerable re-organization of low, medium and high voltage concepts in the 2023.  It usually takes at least two NEC revision cycles for workable code to stabilize.  Since education communities purchase and distribute higher voltage power on large campuses; how can power purchasing and customer distribution system best practice be improved?

This is plenty to talk about.   Join us today at 15:00/16:00 UTC with the login credentials at the upper right of our home page.

Historical Note: Prior to the 2014 NEC, high voltage was defined as over 600 volts, but the threshold was raised to 1,000 volts in the 2014 and 2017 editions to reflect innovation in equipment standards

College and university campuses distribute electric energy in tranches of 10 to 250 megawatts; typically at voltages above 1000 VAC and are generally regarded as load-side services (or regulated utility customers). Two fairly stable sections of the National Electrical Code set the standard of care for these systems — Part III of Article 110 and Article 495.

We will examine them during today’s High Voltage Electric Service colloquium.
