From time to time we break from our interest in lowering the cost of our “cities-within-cities” to enjoy the work of our colleagues responsible for seasonal ambience and public art. We have a dedicated post that celebrates the accomplishments of our gardeners and horticultural staff. Today we dedicate a post to campus fountains–a focal point for gathering and a place for personal reflection for which there is no price.
Alas, we find a quickening of standards developing organizations growing their footprint in the spaces around buildings now. They used to confine the scopes of their standardization enterprises to the building envelope. That day will soon be behind us as an energized cadre of water rights social justice workers, public safety, sustainability and energy conservation professionals descend upon campus fountains with prescriptive requirements for evaporation rates, bromine concentrations, training, certification and inspections. In other words regulators and conformity functionaries will outnumber benefactors and fountain designers 1 million to 1.
We will deal with all that when the day comes. For the moment, let’s just enjoy them.
We are happy to walk you through the relevant structural, water safety, plumbing and electrical issues any day at 11 AM EST during our daily standing online teleconferences. Click on any image for author attribution, photo credit or other information.

From from time to time — particularly in the months of fairer weather, when many events are hosted outdoors — we break form from the grind of responding to c0nsultations to simply enjoy these spaces See our CALENDAR for our periodic Lively c0lloquia when we drill down into technical specifics.

Why the “Arbor” in Ann Arbor Michigan?
Other Ways of Knowing Climate Change
Today we walk through literature governing the safety and sustainability of the open space features of education community estates. Unlike the titles for the building envelope, which are known to most design professionals and contractors, the standards for grounds and landscaping are widely scattered; many of them occupational safety related; created, administered and enforced by units of government.
During the fair seasons we examine the moment in landscape, garden, tree and water literature. We also track titles about the reclamation of building roofs for permeable surfaces and gardens.
During the winter months in the northern hemisphere we include snow and ice management; while covering summer month technologies for southern hemisphere (and vice-versa). Snowfalls in the southern hemisphere are mainly contained to the highlands and mountain ranges, which are almost exclusively in Victoria and Southern New South Wales, as well as the mountains in Tasmania. Winter does not pose as much of a cost burden to education facilities in the southern hemisphere as it does in the northern hemisphere.

Landscape standards refer to guidelines or regulations that specify the requirements for the design, installation, and maintenance of outdoor spaces such as parks, gardens, streetscapes, and public spaces. Landscape standards typically cover various aspects of landscape design, including vegetation selection, planting arrangements, irrigation systems, hardscape materials, and lighting. These standards may be set by government agencies at the federal, state, or local level, or by professional organizations such as the American Society of Landscape Architects (ASLA). Landscape standards aim to ensure that outdoor spaces are safe, functional, and aesthetically pleasing while also promoting sustainability and environmental protection. Landscape standards may also address issues such as accessibility for people with disabilities, water conservation, stormwater management, and erosion control. They may vary depending on the specific location, climate, and intended use of the outdoor space. Compliance with landscape standards may be required for approval of development projects, public funding, or other permits. |
We track the standards catalog of two ANSI-accredited standards developers:
Tree Care Industry Association
Additional practice titles applicable to accessory systems:
ASABE/ICC 802 Landscape Irrigation Sprinkler and Emitter Standard
National Electrical Code: Article 411 Low-Voltage Lighting
National Electrical Code: Article 225: Outside Branch Circuits and Feeders
Illumination Engineering Society (Lighting Library)
Land F/X: Landscape Lighting, Codes, Guidelines and Techniques
OSHA Landscape and Horticultural Services
As a cross-cutting subject involving soil and water and sun many other standards developers, and all levels of government, produce best practice literature for today’s topic. We’ll have a look at what’s moving among those.

Federal regulations that apply to the landscaping of education communities are fairly stable; though land use issues tend to be capricious. Some federal regulations deal with fair trade in the purchase of landscaping materials; others deal with chemical safety; still others deal with personal protective equipment for works.
The federal government recognizes three major segments of this industry:
Landscape Design and Consultation
Landscape Installation and Maintenance
Tree Pruning and Arboriculture
For worker safety we consult the Occupational Safety and Health Administration home page:
Landscaping and Horticultural Services
From time to time we find Notices and Proposed Regulations — or notices of state-level adaptations of federal regulations — whistling across our radar. When they are meaningful and contribute to lower cost we will post the commenting opportunity.
The following voluntary American National Standards Institute (ANSI) titles may be applicable to the landscaping and horticultural units in education communities. Compliance with ANSI standards does not ensure compliance with OSHA policy, although the requirements of some ANSI standards have been adopted within OSHA standards. This list is provided for reference use only.












We maintain all related best practice literature on the standing agenda of our periodic Bucolia teleconferences during which time we sort through proposed regulations, organize a response to them. War stories always welcomed. Stories about successes even more welcomed. See our CALENDAR for the next online meeting.
AWWA C500 Metal-Seated Gate Valves for Water Supply Service | Consultation Closes July 27
The American Water Works Association is one of the first names in accredited standards developers that administer leading practice discovery in backflow prevention consensus documents; usually referenced in local and state building codes; and also in education facility design guidelines and construction specifications.
The original University of Michigan standards enterprise gave highest priority to backflow standards because of their central importance of backflow management to education communities; especially large research universities nested within a municipal water system. Backflow prevention; an unseen technology that assures a safe drinking water supply by keeping water running in one direction by maintaining pressure differences. Analogous to the way we want electrical current to run in one direction, failure of backflow prevention technology poses a near-instantaneous health risk for the contamination of potable water supplies with foul water. In the most obvious case, a toilet flush cistern and its water supply must be isolated from the toilet bowl. In a less obvious case, but at greater scale, a damaged backflow prevention technology at a university research building can contaminate an host-community potable water supply.
There are other ANSI accredited standards developers in the backflow prevention technology space — the International Code Council, the IAPMO Group and ASSE International — for example.
At the moment no AWWA redlines relevant to our objective are open for consultation. Several relatively stabilized product standards are marked up but none dealing specifically with interoperability issues. When they are uploaded you may access them at the link below:

Outdoor play facilities for school children are governed by several key codes and standards to ensure safety and accessibility. The European Standard EN 1176 outlines safety requirements for playground equipment, covering design, installation, and maintenance to minimize risks like entrapment and falls.
The Health and Safety at Work etc. Act 1974 mandates risk assessments and safe environments, while the Occupiers’ Liability Act 1957 (revised 1984) ensures playgrounds are reasonably safe for users.
The Consumer Protection Act 1987 holds manufacturers liable for defective equipment. The Children Act 1989 requires facilities to be suitable and safe. Ofsted emphasizes stimulating, inclusive, and varied play environments that promote physical and mental health, encouraging year-round outdoor learning. Compliance with these standards, alongside regular inspections (e.g., TÜV certification), ensures safe, durable, and engaging playgrounds that foster children’s development while minimizing injury risks.
Today at the usual hour we update our understanding of the technical literature that supports making these facilities safe, sustainable and enjoyable. Use the login credentials at the upper right of our home page.
