I am documenting basic services within a 1/2 mile radius of a project, however within the radius is a large body of water (river port). There are only 9 services close to the project on the near side of the water channel. Other services exist across the water and are within the 1/2 miles radius. The basic services on the other side of this channel can be accessed by travelling outside the 1/2 mile radius or via boat. Does this situation comply with the credit or does the credit specify that the 1/2 mile radius needs to be accessed on foot.
