The home page should have a list of links that cover the main user tasks, as well as allowing the user to search by keyword, subject area, and offer predictive results as they type.
The search engine on the site should be prominent and *work* - ie not produce lists of thousands of PDFs or word documents.
People who live on ward boundaries will want information on things outside of that area. Geocode everything physical or that relatest to specific physical areas, and then allow for browsing via map and other locative means.
Incomprehensible URLs that mean nothing on sight are not useful, but http://mycouncil.gov.uk/wards/edgbaston/councillors is self-explanatory, and good for google.
LGNL is not user friendly but is important for site indexing.
Offer multiple paths to allow users to find what they need quickly.
