Preliminary Damage Assessment
The PDA form is intended for use by the Preliminary
Damage Assessment Team or by Local Government Officials in reporting
disaster-related damages and costs incurred. The completed forms are to
be attached to the "Public Assistance, Preliminary Damage Assessment
(PDA) - Consolidated" form.
For each public facility with significant damage, or
type of work with significant cost, provide a brief description of the
damage and impact on the community. Deduct the value of insurance
coverage. Also provide the approximate percent complete for the work and
cost estimate. Report only those costs or damages which are the result
of the disaster event and are the legal responsibility of the unit of
government or eligible private non-profit organization.
Examples of typical disaster-related work and public facility damages include:
|A. DEBRIS REMOVAL
On streets and Right of Way (ROW)
Discarded personal property on ROW
In drainage channels
At culverts and bridges
|E. PUBLIC BUILDINGS & EQUIPMENT
(Deduct insurance coverage)
Buildings owned by the government or eligible private non-profit organization
Supplies and inventory
Vehicles and equipment
|B. EMERGENCY PROTECTIVE MEASURES
Search and rescue
|F. PUBLIC UTILITIES
(Only those owned by government or
eligible private non-profit organizations)
Water supply systems
Sanitary Sewers systems
Storm drain systems
Power supply systems
|C. ROADS AND BRIDGES
Road surfaces and embankments
Traffic signs and lights
Related structures in ROW
|G. PARKS, RECREATION, OTHER
Owned by governments or eligible
private non-profit organizations
|D. WATER CONTROL FACILITIES
Improved and maintained drainage channels
Dams and watershed structures
EXAMPLES OF DAMAGE DESCRIPTIONS
CATEGORY A - DEBRIS REMOVAL
|Sediments on public property
||Flood debris (rocks, sand, gravel, logs) was deposited on roads, in parks, and other public property.
|Wind-generated debris on public property
||Wind-generated debris consisting of building materials, trees and personal property was deposited on public property.
|Discarded personal property
personal property consisting of clothing, furniture, appliances and
other materials was placed by residents at the curb or other designed
area for pick up.
|Sandbag levee removal
placed sandbag levees to protect community property and public health
and safety. These levees are a safety hazard and interfere with the
resumption of public services.
|Emergency earthen levees removal
placed emergency earthen levees to protect community property and
public health and safety. These levees are now a health and safety
hazard and interfere with the resumption of public services.
|Debris at bridges
||Debris consisting of rock, sand, trees, stump and other material is significantly reducing the waterway opening.
|Minor road slides
||Heavy rains have caused the backslope to slide into the ditch and onto the road.
|Man-made channel clearance
waters deposited sediments in the channel which significantly reduces
channel capacity. The total amount of debris is computed to completely
clean channel to design grade. The applicant's share is deducted from
the total where applicable.
|Timber debris removal along levees and roadways
||Flood waters deposited tree limbs, branches and other floatable debris on riverward face of levee or road embankment.
||Structures were damaged beyond economic repair and represent a health and safety threat to the general public.
CATEGORY B - EMERGENCY PROTECTIVE MEASURES
|Security patrols, search and rescue
operations in damaged areas required the use of personnel, equipment
and supplies for search and rescue. Traffic control and security.
||Emergency sandbag levees were constructed to protect property or to raise or strengthen existing levees.
|Emergency pumping (temporary)
||Flooding required the use of temporary pumps to provide additional pumping capability.
|Emergency pumping (fixed installations)
elevations required the operation of the pumping facilities of a local
protection project. Excess pumping consists of power and labor for the
emergency phase of the operation.
||Operations during EOC activation are eligible to include: labor overtime plus fringe benefits and supplies consumed.
||Provide shelter and food for people forced from their homes by severe weather.
CATEGORY C - ROAD AND BRIDGE
|Aggregate road surface washout
||Roadway surface washed out by floodwaters, includes fill, embankment, ditches.
|Gravel road embankment failure
||Disaster-caused embankment failure and loss of road material.
|Chip and seal failure
||Chip and seal oil surface was damaged by floodwaters.
|Bituminous surface and embankment failure
||Pavement has washed out and failed. Subgrade and ditches scoured.
|Road and culvert washout
||Flood damage to road surface, culvert and ditches.
|Concrete box culvert washout
||High velocity flow destroyed concrete box culvert.
|Stream crossing approach washout
water has washed out the approaches to a stream crossing including the
loss of surface material and rip rap base and left mud and debris.
|Timber wing walls
||Bridge abutments were undermined and wing walls and existing rip rap washed out.
|Curb, gutter and sidewalk damage
||Curbs, gutters and sidewalks were damaged by uprooted trees and/or construction equipment.
||Floodwaters severely damaged/destroyed bridge.
|Soil road washout
||Roadway surface was washed out by flood waters.
|Road, shoulder, embankment failure
||Road, shoulder and embankment were damaged by floodwaters.
CATEGORY D - WATER CONTROL FACILITIES
||High-water damaged levee.
|Erosion damage at draining and outlet structures
||High velocity flow scoured material from behind drainage or outlet structures.
|Gabion bank damaged
||Floodwaters damaged gabion protection and caused erosion.
|Rip rap damaged
||Floodwaters damaged stone slope protection.
CATEGORY E - BUILDINGS AND EQUIPMENT
|Public building clean up
||Floodwaters and floatable debris were deposited throughout the interior of the building.
damaged the building to the point that it is not feasible to repair
(cost of repair greater than 50% of cost of replacement).
|Public building/contents damaged
winds/floodwaters damaged building and contents throughout the interior
of the building. Include costs to protect and secure the site.
CATEGORY F - PUBLIC UTILITIES
||Sewer lines are blocked with debris and/or broken or collapsed.
|Utility line (water, sewer, gas)
|Pipeline river crossing washed out
||High velocity river flows eroded stream banks and bottom to expose and damage pipeline.
|Electrical transmission lines damaged
||Winds/flood/ice caused electrical transmission lines to be damaged.
CATEGORY G - PARK/RECREATION/OTHER
COMPONENTS OF COST ESTIMATES - COMMON EXAMPLES (not all inclusive) - USE PROFESSIONAL JUDGEMENT.
CATEGORY A - DEBRIS REMOVAL
CATEGORY B - EMERGENCY PROTECTIVE MEASURES
- QUANTITY IN CUBIC YARDS (CY) OR TONS
- TRANSPORTATION TO DISPOSAL SITE
- LANDFILL FEES
- RENTAL COST OF ROAD BARRIERS, PORTA-POTTIES
- OVERTIME COSTS OF POLICE, FIREFIGHTERS, OTHER PERMANENT EMPLOYEES
- LABOR COST OF TEMPORARY EMPLOYEES
- EQUIPMENT USE/RENTAL (PUMPS, TRANSPORT)
- COST OF MATERIALS (SANDBAGS, FILL)
CATEGORY C - ROAD AND BRIDGE (PA DOT STANDARDS AND ESTIMATING PARAMETERS PREVAIL)
- TYPE AND QUANTITY OF MATERIALS REQUIRED
- SIZE OF WASHOUT, TYPE OF ROAD SURFACE
- SIZE & TYPE OF CULVERT AND ROAD
- SIZE AND TYPE OF BRIDGE
- SIGNS AND OTHER STRUCTURES
Whenever possible, base the damage assessment on
measurable factors. In some areas such as sewer and water plants the
professional judgment and experience of the plant operator may provide a
reasonable estimate. Include in description of damages the dimensions,
list of major components damages, and/or estimated quantities
(labor,equipment, material) as appropriate and reasonably available.
Use the reverse side of site estimate form for
sketches, discussion of basis for estimate, list of components and
quantities, etc. as appropriate.
The objective is to achieve a reasonably accurate
estimate of the cost of damages. This is NOT the damage survey report
which results in funding, therefore, measurements are approximate, not
to construction tolerance standards.
