KEY POINTS FOR SILVER JACKETS COMMUNITY • EAP policy only applies to USACE operated & maintained dams and levee systems

• Inundation maps now public accessible

• Nondisclosure agreements no longer required

• A security exemption will exist for certain projects

• Policy does not apply to feasibility studies, continuing authorities program, WRDA sec. 203

• National Inventory of Dams will provide state and local emergency managers direct access to EAP maps for USACE dam projects (target November 2021 public release)

• USACE systems provide capabilities that can be leveraged on collaborative projects

HAVE YOU PARTICIPATED IN A USACE EMERGENCY ACTION PLAN EXERCISE?

YES NO

EMERGENCY ACTION PLANS

Including exercises and incident management and reporting

Objective

Timely corrective actions and notifications

5

CONSISTENCY WITH FEDERAL GUIDELINES (FEMA 64*)

Priority to involve emergency managers

Plan organization

Plan name

Evacuation planning responsibility

Project emergency levels

Address area of most immediate impacts

Inundation maps & dissemination

* Also aligned with FEMA 946, DHS-Emergency Preparedness Guidelines for Levees

No Change

EAP ORGANIZATION

Rationale: Consistent organization enhances readability and effectiveness

1. Summary of EAP responsibilities

2. Notification Flowcharts

3. Statement of Purpose

4. Project Description

5. Incident Response Processes

6. Roles and Responsibilities

7. Preparedness

8. Inundation Maps

Required: Consistent order of content

No Change

Desired: Consistent section titles

INTERNAL AND EXTERNAL COMMUNICATIONS

Rationale: Consistent communication procedures by USACE nationwide minimizes confusion

Notification flowcharts

Project emergency levels

Emergency announcements & communications

Warning dissemination to public in immediate vicinity

No Change

COMMUNICATIONS - NOTIFICATION FLOWCHARTS Rationale: Prompt notification is crucial during emergencies

Critical EAP content (BLUF)

–Establishes external and

district-internal command

chain upward reporting

procedures

External notifications have priority

No Change

COMMUNICATIONS: PROJECT EMERGENCY LEVELS

Rationale: Alignment with federal guidelines ensures common understanding

Primary purpose is clear external communication of project condition and incident management activities being undertaken by the project owner.

Previous terms: failure imminent or has occurred, failure situation is developing, non-failure emergency condition

No Change

Rationale: Nearby areas must be evacuated quickly

Required: Description of procedure & means for warning dissemination directly to the general public in the immediate vicinity of the project

COMMUNICATIONS: WARNINGS TO PUBLIC IN IMMEDIATE VICINITYNo Change

AREAS OF MOST IMMEDIATE IMPACTS (EXAMPLE)

11

Is there sufficient warning and response time to allow for evacuations?

No Change

LOCATIONS OF MOST IMMEDIATE IMPACT UPSTREAM Initial flooding upstream of the Dam is anticipated to impact structures along Watercrest Boulevard. Impacts are anticipated to occur if water reaches an elevation of 708.0 feet (NAVD 88), approximately 1.4 feet above the spillway crest. DOWNSTREAM Initial flooding downstream of the Dam is anticipated to have a discharge of approximately 5,000 cfs and combine spillway and residual flows.

INUNDATION MAPS

Policy Briefing and

Implementation Overview

12

POLICY SUMMARY • USACE produced inundation maps are to be released to the public*

• Public release exemption available for security reasons

• Disseminated via National Inventory of Dams – dam emergency action plan maps

• Disseminated via Access to Water – basin maps & events

• Requirement to publish to USACE flood inundation map database

• Local dissemination encouraged via national sources

* This requirement does not apply to feasibility studies, including those conducted under the Continuing Authorities Program and studies conducted by non-federal interests under Section 203 of the Water Resources Development Act of 1986, as amended.

PUBLIC RELEASE EXEMPTION FOR SECURITY REASONS

Paragraph 7d(1)

• Does not restrict access by other federal/state/local emergency management agencies

• Requires concurrence by USACE Director of Civil Works

• Complete in normal engineering processes like EAP, risk/security assessments, not during emergencies

• Concerns about public reaction during an emergency are not indicative of a credible security threat to a project

• May still be discoverable under FOIA – consult counsel 15
