Anchor Links Jump Too Far Down

http://blackrockhomes.com/

I’ve set up anchor links in my main navigation. If I click on one of them, such as http://blackrockhomes.com/communities/#east-valley, from the homepage or any other page the page lands really far down from where I want it to be. If I click on one from the page itself it works just fine. Can you provide me with some help?
