Traffic Impact Study – A report initiated in response to a proposed<br />

development that compares the anticipated roadway conditions with and<br />

without the development. The report may include an analysis <strong>of</strong><br />

mitigation measures.<br />

Access Connections:<br />

All connections in <strong>Garner</strong> shall meet or exceed the minimum connection<br />

spacing requirements as specified in Table 1 (refer also to Figure 2).<br />

• Spacing between driveways or medians shall be measured along the<br />

right‐<strong>of</strong>‐way line between the tangent projection <strong>of</strong> the inside edges<br />

<strong>of</strong> adjacent driveways, opposite street driveways or median openings.<br />

• The <strong>Garner</strong> <strong>Town</strong> Engineer may reduce the connection spacing<br />

requirements for situations where they prove impractical, but in no<br />

case shall the permitted spacing be less than 85% <strong>of</strong> the standard.<br />

Spacing below 85% <strong>of</strong> the standard will require the issuance <strong>of</strong> a<br />

variance.<br />

• For sites with insufficient road frontage to meet minimum spacing<br />

requirements, consideration shall first be given to providing access via<br />

connection to a side street, utilization <strong>of</strong> a joint or shared driveway<br />

with an adjacent property that meets the recommended spacing<br />

requirement, or development <strong>of</strong> a service road to serve multiple<br />

properties.<br />

• The <strong>Garner</strong> <strong>Town</strong> Engineer, in coordination with the North Carolina<br />

DOT, may grant access approval for a permanent use not meeting the<br />

spacing requirements <strong>of</strong> these guidelines on an interim basis if an<br />

access plan is submitted that demonstrates how spacing<br />

requirements will ultimately be met and appropriate assurances in<br />

the form <strong>of</strong> a recordable and enforceable easement <strong>of</strong> access<br />
