Guidelines and Specifications for Flood Hazard Mapping Partners [April 2003]

1.1.2

Project Scoping

[February 2002]

The Project Scoping phase begins after a community's mapping needs have been identified and
FEMA and the community have decided to initiate a Flood Map Project to create or update the
FIRM, Building on the Mapping Needs Assessment, Project Scoping entails the following:

. Conducting background research and community outreach;

. Determining what flood hazard data (e.g" those data shown in effective PIS reports and
on effective F1RMs and FBFMs) can be used in the revised flood hazard analyses and/or
transferred without change to the new FIRM and FIS report;

. Identifying other data needed to complete the Flood Map Project and sources of those
data (e.g" base map, topography, cross sections, transects);

. Establishing priority levels for flooding sources to be analyzed and mapped;

. Determining whether the FIRM format should be countywide or community-based,
digital or manual, and what tiling scheme should be used;

. Developing schedules and cost estimates for the: components of the Flood Map Project;
and

· Assigning proj ect tasks to Mapping Partners and developing appropriate contracts or
agreements for completion of assigned work.

All Mapping Partners contributing to the Flood Map Project, including the affected communities,
will participate in the Project Scoping phase. The Project Scoping process is discussed in detail
in Section 1.3.

1.1.3

Topographic and Flood Hazard Data Development/Report and
Map Production [February 2002]

After the Project Scoping phase has been completed and all contractual orders to initiate work
have been issued, the Topographic and Flood Hazard Data Development/Report and Map
Production phase of the Flood Map Project begins. This phase may entail the following:

· Developing and/or obtaining topographic and cross-section data needed for engineering
analyses and floodplain boundary delineations;

· Performing engineering analyses and delineating floodplain boundaries;

· Obtaining and preparing the base map for FIRM production;

· Digitizing directly from the effective FIRM those floodplain boundaries that are not
being updated;
