Public Hearing Part 2

Residents

2 of 28

Background

You just heard the news that the planning board decided NOT to issue a permit until the solar farm has been redesigned to include a landscape buffer.

Both SolarX and the residents will present their own redesigns at the final public hearing.

3 of 28

Updated task leaders

In addition to the same tasks as before, every team member can propose their own redesign (regardless of their role).

Your team will review the redesigns from each team member and choose one as the final design to present during the public hearing.

Task Leader

Main Responsibilities

Resident Lawyer

Will argue for the proposed design revision and present the oral testimony.

Resident Engineer

Will collect evidence and prepare exhibits for the lawyer to present during the testimony.

Resident Secretary

Will take notes and record answers for the group.

Solar Farm Redesign

8 of 28

New design criteria

Yearly profit: You don’t care, but the planning board cannot approve designs with negative profit.

Visibility: The redesign must include a landscape buffer that decreases its visibility, at least for you.

  • There’s no law for how low the visibility needs to be, so use the visibility analysis data and screenshots from different points of view to prove that your design meets this requirement.

Yearly output: The planning board will only approve designs with at least 100,000 kWh of yearly output.

9 of 28

New design constraints

Land: Your design should be within the boundary of the site.

Trees: Trees cannot be inside the resident property lines or on the sidewalk (see image)

Maintenance: The inter-row spacing should be at least 2m.

Wind resistance: The tilt angle of solar panels should not exceed 35º.

New design variable: Trees

  • The landscape buffer may use any combination of tree types/sizes.
  • There are two types of trees:
    • Deciduous trees shed leaves in winter and provide screening only from spring to fall
    • Evergreen trees don’t shed leaves and provide screening all year long

  • Short trees (<6m) cost $20/year. Tall trees (>=6m) cost $60/year.

Aladdin Tips: People (Observers)

You can drag the residents anywhere within their property lines - even onto the roof or the sidewalk!

When designing the landscape buffer, think: Which point of view has the highest visibility for a resident?

Choose the final design

Each team member will iterate as much as they can, so the you team can have at least 3 candidates for the final design.

When your group has enough candidates, discuss which design you will choose as the final design to present at the public hearing by considering all of the criteria and constraints. Review the Aladdin models and each other’s design journals to help you decide.

Final design: [Aladdin file name of final design]

Reasons for choosing: [write down reasons]

Preparing the Argument / Oral Testimony

Task Leader: Resident Lawyer

16 of 28

Argument: Claim

Since the planning board has decided to require a redesign, your new goal is to convince the planning board to choose your design - or at least, to make sure that whichever design the planning board ends up choosing, it always has the residents’ interest in mind.

Make a claim about why your solar farm proposal should receive the permit.

Answer: I claim that the proposed solar farm benefits the city by [fill in the claim here…]

The proposed solar farm will also protect the residents’ interest by [fill in the claim here…]

17 of 28

Argument: Evidence

Ask the resident engineer for exhibits that can serve as evidence to support your claim.

Acceptable exhibits include (but are not limited to) analysis results, calculations, graphs, and screenshots.

Answer: To support my claim, I would like to present two exhibits.

Exhibit A is a screenshot of a computer model of the proposed solar farm design, generated with Aladdin.

Exhibit B is [describe the evidence here…]

18 of 28

Argument: Reasoning

Explain the reasoning why the exhibits support your claim. Include any solar science concepts and engineering design principles that goes into your decision making.

Ask the resident engineer for help if needed.

Answer: As exhibit A shows,

  • a tilt angle of 35º [fill in the reasoning here…]
  • an inter-row spacing of 5m [fill in the reasoning here…]
  • [add more reasoning here…]

As exhibit B shows,

  • [fill in the reasoning here…]

Ask the secretary to send your argument (including claim, evidence, and reasoning) to the planning board clerk (as text, through email) before the public hearing.
