All vehicle speeds on unpaved roads shall be limited to a maximum of 15 miles per hour.

Setback verification is required for setback distances when structural development is located up to or within one foot of the minimum required setback on conventionally zoned properties and when structural development is located within five feet of a property line, right-of-way, or access easement on planned district zoned properties.

In the event that archaeological, historic, or paleontological resources are discovered during any construction, construction activities shall cease, and the Agency shall be notified so that the extent and location of discovered materials may be recorded by a qualified archaeologist, and disposition of artifacts may occur in compliance with State and Federal law.

These standards apply only to tree removal that takes place during the nesting seasons of March 1 and April 15 or between September 1 and October 15.

For the purposes of protecting nesting birds, outdoor construction activity that involves tree removal, grading, or other site disturbances in an area where a biological assessment has identified a high probability of the presence of nesting birds are subject to the requirements enumerated below before and during site preparation and construction activities, unless separate project mitigation measures have been adopted that override these requirements.

The general height limit for fences and screening walls is the same for other detached accessory structures, provided they meet the required setback. The required setback shall be either that setback established by the governing conventional district, an established building envelope, or the setbacks set forth in the R1:B3 zoning district if no other setbacks apply.

Retaining walls may reach a maximum height of six feet above grade if the exposed face of the retaining wall faces into the center of the property. Retaining walls may reach a maximum height of four feet above grade if the exposed face of the retaining wall faces outward from the center of the property, unless they are at least 25 feet from all property lines, in which case they can reach a maximum height of 8 feet above grade.

Retaining walls may reach a maximum height of six feet above grade if the exposed face of the retaining wall faces into the center of the property. Retaining walls may reach a maximum height of four feet above grade if the exposed face of the retaining wall faces outward from the center of the property, unless they are at least 25 feet from all property lines, in which case they can reach a maximum height of 8 feet above grade.
