Draw a balancing feedback loop

This exercise will help you practice drawing balancing loops.
The City of Los Angeles has set a number of short, medium and long-term goals for improving the city's water, energy, climate, transportation, green jobs, housing and wages over the next 20 years. Your task is to draw a balancing feedback loop to describe how L.A. is moving towards one of its goals.

Hint: A balancing loop is made up of four elements - a performance variable, a goal, a gap and a corrective action. You should start by identifying these variables and then add other variables as needed to make your story as clear as possible. The document "Seeing and drawing balancing feedback" in the additional materials may help.

A suggested worked solution is provided in the references section.

It's Earth Day. So how is LA doing?

Balancing loop~odd number of polarities

**Performance Variable*: Resource Useage (currently, water use is 106 gallons per capita per day)

**Goal: Target/Sustainable level set by Plan (20% reduction by 1/2017)-->a **gap* (reduction of 19% since 2015)

**Corrective Action*: Change in Useage (decrease useage by 1% for 2017)
