Creek Turnpike UFST crew (Barbara White, John Slater and Dudley Hartel) has one final news interview.

February 29

Set up Storm Damage Protocol (SDP) segments in Edmond, OK. UFST crews work with Carrie Tomlinson, Edmond City Forester to implement a pre-storm assessment of debris.

UFST Crew Inventorying for Pre-storm SDP

Carrie Tomlinson, Mark Bays, Barbara White and Jim Clark discuss SDP inventory on Main St in Edmond. OK.

The city was stratified into 4 sections based on development type (age) and existing canopy. Within those strata, the street segments were identified as either residential, or commercial/institutional. Sampling was designed to include more samples along residential streets.

This detailed stratification was supported by the city's GIS layers that included tree canopy.

February 28

Trees along the remaining trails at the Oxley Nature Center are assessed.

Mohawk Park completed! Assessment of trees in remaining parks begins after lunch.

UFST crews have 3 news interviews (2 Tulsa and 1 statewide on OETA) on their work.

February 27

Trees along the trails at the Oxley Nature Center and in the Disk Golf Course (Frisbee) are assessed.

February 26

Tree assessment work continues in the remaining areas of Mohawk Park including Oxley Nature Center.

Ice Response: Week 1 Begins [February 5 - 8]

February 8, 2008

In discussions with Tulsa Parks & Recreation this week and localFEMA Debris Management Teams, it is apparent that park tree inventorydata can play a critical role in disaster response beyond its intendedmanagement use. This "Tulsa Model" is based on an individual treeinventory with tree location determined with GPS. This inventory oflocation, species, and DBH provided sufficient information that thedata could be quickly updated by Parks & Recreation arborists toidentify ice damaged trees as either recommended removals, or forrestoration pruning.

Under a pilot program thatFEMA is testing for debris payments to communities, FEMA DebrisManagement Teams meet with a state emergency management debrisspecialist and community representatives prior to debris cleanup toestimate and agree on a the amount of debris to be removed and apayment for that work. Once the agreement is made, the communityreceives payment and can begin debris removal. Records must be kept,but not at the level of detail as currently required.

Under the current debris program, communities begin debris removaland document all work. Following debris cleanup, the communities thenapply to FEMA for reimbursement based on the documentation.

There appear to be several advantages to the pilot program for communities:

  • the amount of payment is known before work begins
  • documentation is not used to justify payment
  • communities have funds up front to contract or complete work in-house
  • communitiescan contract for debris removal (cutting trees & limbs) and at thesame time specify restoration pruning to ANSI 300 or communitystandards; previously, communities would have broken limbs cut based onFEMA standards and then have to contract or schedule restorationpruning as a separate project

After walking Veterans Park in Tulsa, the FEMA Debris ManagementTeam quickly determined that the data (park tree inventory) previouslycollected by Parks & Recreation could be used reliably to determinepayments for the "standing debris". Parks & Recreation staff thencreated individual cost sheets for each park they had previouslyinventoried based on their post-disaster damage assessment. BecauseFEMA estimates debris in two main categories which I term "standingdebris" and "ground debris", the FEMA Debris Management Team still hadto visit each park to estimate the ground debris component that Parks& Recreation staff had not captured in their assessments. However,the inventory data for park trees saved FEMA many man-hours ofassessment in Tulsa. Ground debris is composed of any woody debris thatis not attached to the remaining tree, or a tree that is entirely uprooted and laying on the ground. "Standing debris" is composed of trees that meet one of the following FEMA debris standards:

  • >50% crown damage (whole tree removal)
  • >30% lean (whole tree removal)
  • trunk heartwood exposed (whole tree removal)
  • FEMA hangers; broken limbs that remain attached to the tree (cut 6" behind break)

Broken limbs that remain in the crown but are not attached are notcounted as FEMA hangers. The debris payment agreement is based on thetree counts that meet these criteria (see February 19th example costsheet for Oklahoma unit costs).

Note that in this set of criteria, FEMA's focus is on debris cleanup not cleanup and the reduction of risk.

Because of the volume of work to be done, Tulsa Parks &Recreation requested assistance from Oklahoma Forestry services (MarkBays, U&CF Coordinator) to help assess trees in several parks wherethey lacked the initial inventory. UFST storm damage assessment crewswere mobilized to assist in those parks and other communities in theTulsa and Oklahoma City area (Bixby, Nichols Hills, Edmond, Muskogee).

Although work during this ice storm response has been limited topark trees, there is no reason that a street tree inventory could notbe used in the same manner.

Because of the FEMA pilot program, UFST assessment procedures weremodified to support the data that Tulsa needed for prepayment of debrisfunds. UFST crews made the following determinations:

  1. does tree qualify as FEMA removal
  2. does tree qualify as FEMA hanger
  3. what risk is associated with this tree if not FEMA debris in #1 and #2
    1. hazard removal
    2. hazard pruning
  4. for trees that are not FEMA debris and not identified as hazard, is restoration pruning recommended

In this list, items #1 and #2 are compatible with FEMA's mission toassist communities following disasters, while items #3 and #4 andnon-FEMA tasks that communities must address outside of the debrisprogram.

At the conclusion of the UFST assessments, a community will receive:

  1. a cost sheet suitable for FEMA discussions under the debris management pilot program
  2. a list of other trees considered as a risk to the public (removals and pruning)
  3. a list of additional trees that require restoration pruning

For post-disaster assessments, the UFST crews can make debris and risk assessments in one of two ways:

  1. when pre-storm inventories are not available, recordlocation (GPS), species and diameter for "standing debris" andcommunity risk or restoration (non-FEMA)
  2. when recentinventories are available, make the same assessments and merely updatethe post-disaster condition into FEMA and non-FEMA recommendations (noGPS needed)
