Irrigated Parks Increase Property Values

By September 12, 2022 No Comments

A recent study quantifies the effects of proximity to irrigated parks, but where will water for irrigation come from?

 

In some regions, calls are mounting to end public park irrigation to save water, but is losing the benefits of irrigated parks worth the water savings? While it is well understood that parks raise real estate values, the value change associated with park irrigation was never quantified until a University of Western Australia researcher published a study on the subject this summer.

 

Urban parks provide recreation, health, and environmental benefits — such as cooling and improved air quality — that can push property values up. In the past, parks had only been studied using criteria including their size, location, and purpose. The new study, however, focuses specifically on the effects of park irrigation on property values.

 

Study author Claire Doll compared both small and large parks in the Perth metro region of Australia. Using the size of parks and their volume of irrigation, Doll estimated average property price increases for four kinds of park areas in neighborhoods with three different housing densities.

 

Irrigation Benefits Compared

The study paints a picture of how only irrigated parks increase property values with an exception, which was that nonirrigated parks do somewhat increase property values in high-density areas. Other results included:

 

  • Only apartment prices are increased by nonirrigated parks in the neighborhood.
  • Only small, irrigated parks increased the value of low-density properties.
  • As small, irrigated park area increased by 1%, property prices rose an average of 0.0013% for an average increase in property price of AU$725 (US$493).
  • Only large, irrigated parks increased the values of medium-density properties. As park area grew by 1%, property values increased by an average of 0.0025% for an increase per property of AU$1,143 (US$777).
  • In all park classifications, high-density property values increased with park area. A 1% increase in small and large irrigated park area was associated with a 0.0088% and 0.0035% growth in property value, respectively. A 1% increase in small and large nonirrigated park area, however, was associated with an average property value increase of 0.0041% and 0.0072%, respectively, for an average increase of AU$1,385-3,482 (US$941-2,366) per property.

Doll suggests that with growing urbanization and higher-density living, development of nonirrigated parks may add value. Where medium- and low-density properties abound, however, nonirrigated parks may deliver no benefits.

 

Because Perth’s climate is marked by hot, arid summers and mild winters, and water must be used judiciously, the study’s findings may be difficult to generalize to all regions. Yet other regions with similar climates and water issues, such as the Texas Hill Country and its surrounding regions, may well be able to put the new information to use, especially with booming population growth and climate change putting new stress on freshwater resources.

 

Decentralized Treatment and Urban Park Irrigation

Is there a middle ground between irrigating foliage with scarce drinking water and curtailing park irrigation?

 

Small-scale decentralized water infrastructure can be constructed to treat and reuse neighborhood wastewater for park irrigation and many other nonpotable applications without stressing scarce drinking water resources. Decentralization simply means using smaller, purpose-built plants right where they are needed. Municipal collection networks already exist, so sewer mains may be tapped for feed water to produce irrigation-ready water, and with effluent used nearby, no long water pipelines need be built.
