At the December 6, 1993 meeting of the City Council. Councilman Thomas requested a report from the Orange County Fire Department regarding the fire risks to the City at the Wildland/Urban The Fire Department conducted field inspections in December to assess the situation.

The Fire Department has also recently formed a Wildland/Urban' interface task force. Building official, Rick Brown is a member of the task force representing the City of Tustin. The purpose of the task force is to identify problem areas and to draft recommendations for standards to address life safety and property safety issues in these areas.

This review looked at the interface areas from three vantage points. The cul-de-sac on the end of Township, the deadend of Foothill and the firea'oad on the end of Peters Canyon Road. The existing protection for most of this area is an approximately thirty feet wide fire break, maintained each year by diking the ground in the fire break area.- . . . The condition of the fire break is good in some areas and non existent in others due to existence of Eucalyptus groves. In thc .areas where the groves meet the city/county 1/ne a very serious' problem exist. The fire break needs to be widened to 100 feet. This added to the private property of county residents would provide a defensible space as recommended by the fire department. This fire break shall be maintained at all times to the following minimum standards and are r~-,,ommendations to reduce the tth-eat of conflagration in this high risk area. All areas within the I00 feet area need to be maintained free of al! combustible vegetation. This maintenance will need to be done at a mirdmum of twice a year and as needed. All dead or dying Eucalyptus trees within the 100 feet areas must be removed and properly disposed of. All living Eucalyptus trees within the 100 feet area must be trimmed up from the bottom of the tree at a minimum of 20 % of the height of the tree. RESIDENTIAL SPRINKLERS At,ID SMOKE DETECTORS SAVE LIVES DEC 2~ '93 12:34PI~ P.3/4 Mr. Brown December 27, 1993 Page Two · All living Eucalyptus trees within the 100 fl area which are within 10 ft of any structure must be trimmed back to at a minimum of the.property line and/or 10 ft away from any structure. In regards to the eucalyptus groves, it a~ that some maintenanee and thinning along with the removal or cutting down of some dead trees would provide a higher level of protection against a conflagration. Some qu~tions regard§ this action may need input from environmental groups and include: Can eucalyptus be removed or thinned as a requirement of the city's Hazard Reduction Program? Which environmental groups or governmental agencies, if any, will need m review proposals to remove or trim eucalyptus trees? If trees are cut down, can they be left'to decay on thc property, or shall they be removed 'after following the required procedure for trees with bore beetle infestation?- If the trees are to be thinned, how far into the interface area would thinning allowed or required.* Can trees be removed to provide for a wider fir~. break? To what extent can coastal sage habitat be thinned to reduce fuel load near' Assistance from the planning depar~ent will be necessary to answer some of these que.stions. In regards to the coastal sage habitat, thc fire deparUnent has been working with the U.S. Fish and Wildlife Service (USFWS) on similar issues in other areas. So far, they have allowed thinning in similar situations where fire hazard concerns have been identified. This only take~ consultation with USFWS to obtain an answer. Monitoring of wildland interface axeas should be through the City department that I~rforms the hazard reduction and or weed aba~ment programs for the City. Thc firc department is av~.ilablc to consult with the city on Midland management questions that may arise. Areas of Fire Department concern are listed as follows: HIGH (Chaparral,Eucalyptus,European Grasses) · Open space area behind Vista Luces DEC Z8 ' ~3 L 3: 35P1'"1 F'. ,:1/4 Mr. Brown December 27, 1993 Page Three · East end of Racquet Hill * East end of Foothill, between Foothill and Covey MEDIUM (Chaparral, European Orazses) · Fast end of Lower lake Dr. behind Lake Court · Behind 2165 & 2121 Lemon Heights Dr. · Directly behind the Tustin Hills Racquet Club LOW (European Grasses) · South of the racquet club following around Pavi!lion and Salt Air Dr. BetWeen thc East end of Fairweather. Rd. and new developments in thc- La Colina area. Regulations to provide fire safe structures and interface would be located in one of three documents. These documents include: the land use planning document, the building code or planned community requirements. The fire department would have input into these documents through the review process. Any area that showed a wildland interface in the tract or site development-plans would have requirements for fuel modification zones. The fire department is cijrrently working on addressing building and fire code requirements fo~ those areas designated az very high fire hazard areas. These codes would affect those areas defined and documented under the requirements of the Bates Bill (AB337)'. The City will be contacted for review of these proposed code changes as soon as they have been formalized.
