The site doesn't seem to have a focus or purpose. Users come to municipal or eGovernment websites for specific purposes.
And unless the purpose of the site is helping people who are lost, the map and splash page isn't informative.
There are lots of best practices. For example Search Box upper right of the top page. Find out the top three or four tasks users come to the site for, then give them top page priority. For example, post the most important government bills being voted on and provide a calendar of important events and pending legislation.
It tourism is a priority, make the site more likely to encourage people to spend their vacations there. If business investment is a priority, design the site with the information foreign investors need. For example, explain how you've streamlined the building process, have a highly educated technically savvy workforce, improving economic conditions in five key areas, and
put the information on the top page.
And study what others are doing. They may not be exactly right for your country, but do show a focus on what users do on city or regional government websites.
San Diego doesn't approach the site like an abstract exercise. People go to the site for specific departments, and that's what they find.
Indiana's eGovernment site figures prominently in best practice studies, earning a solid "A" rating. In particular, read
the article posted on the redesign from an agency focus to customer focus. The Indiana site has a map, about one tenth the size. Why? Because either you're in Indiana, know about where Indiana is, or couldn't care less. None of these require a big map on the top page.
But then you have to understand best practices and study what others have done. Designing eGovernment websites is not an abstract academic exercise. People come to the site with specific expectations and tasks they want to accomplish.
