Wildlife Connectivity

  • Wildlife Connectivity Guidance
    • This overview provides an introduction and background to wildlife escape measures, wildlife funnel fencing, and wildlife passage structures. This document also includes a case study on State Route 260.
  • Wildlife Escape Measures
    • The wildlife escape measures listed below are designed to allow animals to escape from getting caught within existing roadway fenced corridors. In this way, these measures will help reduce wildlife-vehicle collisions and sustain existing wildlife connectivity patterns of movement in the state. Details A through F, which are explained the Description of Wildlife Escape Measures text, are engineering drawings to help the project manager include the appropriate wildlife escape measure during final design.
    • Detail A (One-Way Gate)
    • Detail B (Large In-Line Wood Plank Ramp)
    • Detail C (Large Corner Wood Plank Ramp)
    • Detail D (Large In-Line Concrete Ramp)
    • Detail E (Small Escape Ramps)
    • Detail F (Slope Jumps) 
  • Wildlife Funnel Fencing
    • Fencing that serves to funnel wildlife toward passage structures is critical to promoting highway passage. The wildlife measures listed below are suggested fencing to funnel wildlife across highway corridors with the aim of reducing wildlife-vehicle collisions. Details A through H, which are explained in the Wildlife Funnel Fencing text, are engineering drawings to help the project manager include the appropriate wildlife funneling measure during final design.

Section 404/401

The primary documents prepared to acquire Section 404 permits from the U.S. Army Corps of Engineers include Preconstruction Notifications (for projects that do not require an individual permit) and Individual 404 Permit applications.

As part of the Section 404 permitting process, ADOT applies for Section 401 Water Quality Certification from the U.S. Environmental Protection Agency (for projects on tribal lands) and the Arizona Department of Environmental Quality (for projects on nontribal lands).

404 Permit Applications

Note: All NWP PCN applications should include documentation that the project is in compliance with the 31 General Conditions associated with the 2012 Nationwide Permits and Regional Conditions 1-4, 9, and 10. Form 4345 should be used for Nationwide Permit Preconstruction Notifications and Individual Permit applications.

New! Stormwater Templates

These documents are intended for use statewide and are available.

The SWPPP template offers practical guidelines for meeting regulatory requirements when operating construction projects on tribal and non-tribal lands. Both NPDES (2012) and AZPDES (2013) Construction General Permit requirements are included as options when preparing this document. Inapplicable information may be deleted, as necessary.

The Monitoring SAP template accommodates document preparation for projects on non-tribal land that require sampling and analysis in accordance with the AZPDES Construction General Permit (2013).
