Or find the PIO (Public Information Office) or equivalent and state your case that allowing fishing would be another way of serving the community. The reasonable requirement of not making a mess would of course apply but that would be enforced on any user of the grounds. The worse that can happen is that he/she will say ?No? in which case you are only out an email, letter or visit and back where you started.

I have done this twice, once on a private pond in an exclusive development (answer = No) and once at an Industrial Park where all they said was pick up after yourself. The second case had a sign saying ?No use by non-residents?. I explained I used to work for one of the companies in the park and fished during my lunch hours and missed doing so. The Head of Security gave me the go-ahead. I even fished it in my float tube a few times.
