I should start by declaring that I am a politician with an environment brief. I don’t mind being called a ninth grader (or anything else) as long as you vote for me! (Actually I am post graduate educated in a numerate discipline – but not all politicians are.)
I like what you have done so far but could I suggest it be topped and tailed. Nothing wrong with the introduction but it needs an even shorter abstract telling your audience what you are going to tell them. Then finish off with a few sentences in conclusion telling them what you told them. Did any of that make sense? Politicians like to think they are terribly busy and will not read past the first paragraph it they don’t think it will solve their current problem.
The other thing I would have liked to see is just a few details of the alternatives you have looked at – maybe in the form of a comparison table – which I think would help explain why you prefer this particular solution. (So do I by the way)
