Land at Highover Farm, Hitchin
The Movement and Access Plan sets a street hierarchy across the site. The draft Design Code seeks to add detail to set out specifications in terms of width, surfacing, use, parking, traffic speeds and landscaping according to the street type.
The images on this page identify that produced to guide the primary road and secondary roads. Further detail for other streets can also be viewed in the draft Design Code booklet.
