Disaster Assistance

Preliminary Damage Assessment




Form Instructions

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)
In parks
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
Evacuation efforts
Security patrols
Search and rescue
Emergency pumping
Emergency access
 
F. PUBLIC UTILITIES
(Only those owned by government or
eligible private non-profit organizations)

Water supply systems
Sanitary Sewers systems
Treatment plants
Storm drain systems
Power supply systems
C. ROADS AND BRIDGES
Bridges
Culverts
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
Levees
Improved and maintained drainage channels
Dams and watershed structures
Irrigation works
 


EXAMPLES OF DAMAGE DESCRIPTIONS

CATEGORY A - DEBRIS REMOVAL
SUMMARY TITLEDAMAGE DESCRIPTION
Sediments on public propertyFlood debris (rocks, sand, gravel, logs) was deposited on roads, in parks, and other public property.
Wind-generated debris on public propertyWind-generated debris consisting of building materials, trees and personal property was deposited on public property.
Discarded personal propertyDamaged 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 removalApplicant 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 removalApplicant 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 bridgesDebris consisting of rock, sand, trees, stump and other material is significantly reducing the waterway opening.
Minor road slidesHeavy rains have caused the backslope to slide into the ditch and onto the road.
Man-made channel clearanceFlood 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 roadwaysFlood waters deposited tree limbs, branches and other floatable debris on riverward face of levee or road embankment.
DemolitionStructures were damaged beyond economic repair and represent a health and safety threat to the general public.

CATEGORY B - EMERGENCY PROTECTIVE MEASURES
SUMMARY TITLEDAMAGE DESCRIPTION
Security patrols, search and rescueEmergency operations in damaged areas required the use of personnel, equipment and supplies for search and rescue. Traffic control and security.
Sandbag leveeEmergency 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)Flood 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.
EOC operationsOperations during EOC activation are eligible to include: labor overtime plus fringe benefits and supplies consumed.
ShelteringProvide shelter and food for people forced from their homes by severe weather.

CATEGORY C - ROAD AND BRIDGE
SUMMARY TITLEDAMAGE DESCRIPTION
Aggregate road surface washoutRoadway surface washed out by floodwaters, includes fill, embankment, ditches.
Gravel road embankment failureDisaster-caused embankment failure and loss of road material.
Chip and seal failureChip and seal oil surface was damaged by floodwaters.
Bituminous surface and embankment failurePavement has washed out and failed. Subgrade and ditches scoured.
Road and culvert washoutFlood damage to road surface, culvert and ditches.
Concrete box culvert washoutHigh velocity flow destroyed concrete box culvert.
Stream crossing approach washoutHigh 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 wallsBridge abutments were undermined and wing walls and existing rip rap washed out.
Curb, gutter and sidewalk damageCurbs, gutters and sidewalks were damaged by uprooted trees and/or construction equipment.
Bridge destroyed/damagedFloodwaters severely damaged/destroyed bridge.
Soil road washoutRoadway surface was washed out by flood waters.
Road, shoulder, embankment failureRoad, shoulder and embankment were damaged by floodwaters.

CATEGORY D - WATER CONTROL FACILITIES
SUMMARY TITLEDAMAGE DESCRIPTION
Levee damageHigh-water damaged levee.
Erosion damage at draining and outlet structuresHigh velocity flow scoured material from behind drainage or outlet structures.
Gabion bank damagedFloodwaters damaged gabion protection and caused erosion.
Rip rap damagedFloodwaters damaged stone slope protection.

CATEGORY E - BUILDINGS AND EQUIPMENT
SUMMARY TITLEDAMAGE DESCRIPTION
Public building clean upFloodwaters and floatable debris were deposited throughout the interior of the building.
Building destroyedTornado/floodwaters 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 damagedHigh winds/floodwaters damaged building and contents throughout the interior of the building. Include costs to protect and secure the site.

CATEGORY F - PUBLIC UTILITIES
SUMMARY TITLEDAMAGE DESCRIPTION
Sewer blocked/brokenSewer lines are blocked with debris and/or broken or collapsed.
Utility line (water, sewer, gas) 
Pipeline river crossing washed outHigh velocity river flows eroded stream banks and bottom to expose and damage pipeline.
Electrical transmission lines damagedWinds/flood/ice caused electrical transmission lines to be damaged.

CATEGORY G - PARK/RECREATION/OTHER
SUMMARY TITLEDAMAGE DESCRIPTION


COMPONENTS OF COST ESTIMATES - COMMON EXAMPLES (not all inclusive) - USE PROFESSIONAL JUDGEMENT.

CATEGORY A - DEBRIS REMOVAL
  • QUANTITY IN CUBIC YARDS (CY) OR TONS
  • TRANSPORTATION TO DISPOSAL SITE
  • LANDFILL FEES
CATEGORY B - EMERGENCY PROTECTIVE MEASURES
  • 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.
