APPENDIX D – SUBDIVISION REGULATIONSAPPENDIX D – SUBDIVISION REGULATIONS\Appendix A Street Sections

Appendix A presents typical cross-section designs of streetscapes using the standards and guidelines Article 4. It is exemplary of the application of the street network and design standards and guidelines, and is not exhaustive. Other similar cross sections could be designed by applying the standards and guidelines, depending on the context of the street. The cross-sections illustrate the planning and urban design concepts in these regulations and upon approval through the platting process may be the basis for engineering and construction documents.
