I decided I would post this to help others trying to do the same with Materialize CSS. You can change the height of the navigation bar and the size / location of the map.

Demo
HTML
<nav>
<div class="nav-wrapper">
<a href="#" class="brand-logo left"><i class="material-icons">list</i></a>
</div>
<div class="nav-wrapper">
</div>
</nav>
<
<<div class="row" id="card-placement"> <!-- id added here -->
<div class="col s12 m8 offset-m2">
<div class="card grey lighten-5">
<div class="card-content grey-text text-darken-1">
<h5 class="head">Title</h5> <!-- class added here -->
<div class="divider"></div>
<p>Stuff goes here</p>
</div>
</div>
</div>
</div>
CSS
#card-placement{
margin-top:-60px
}
.head {
margin-top: -2px;
}
nav {
color: #fff;
background-color: #ee6e73;
width: 100%;
height: 112px;
line-height: 56px;
}
.nav-wrapper {
margin-left: 20px;
}
