FINANCIAL STATEMENT : No measurable cost to City. Fees will offset expenses . DESCRIPTION : At the City Council meeting of April 27 , 1987 , a public hearing was held in connection with the adoption off—fdie Fire Safe Roofing Ordinance . After the public hearing was closed , the matter was referred to Staff to investigate the feasibility of requiring spark arrestors to be installed within a specified time and to review the standards for spark arrestors . The issue of spark arrestors has been resolved by the adoption of an ordinance requiring spark arrestors to be installed when work exceeding $ 1 , 000 . 00 is being done , or when property is sold . The City Council conducted a public hearing on the Fire Safe Roofing Ordinance on July 27 , 1987 and introduced the ordinance . Section I of the proposed Fire Safe Roofing Ordinance deletes the provisions that exempts single family dwellings & accessory buildings from the requirement for permits . It should be emphasized that the intent of requiring a permit is to assure that the applicant will be advised of the material requirements in the three roofing areas . Inspections will be made and will be limited to assuring that the proper materials have been used . Inspections made after the roofing has been completed cannot assure compliance with other aspects of the code . Section .II of the ordinance establishes the following three roofing areas : Roofing Area 1 requires a Class B roof covering or non- combustible roofing material . Any reroofing in this area must comply with requirements for new construction . Reroofing should not be a problem because all buildings in the area have concrete tile roofs . Roofing Area 2 requires a Class C roof covering or non- combustible roofing material . Any reroofing in this area must comply with requirements for new construction . There are 71 houses in Tract 4930 , ( Estate Homes ) and 146 houses in Tract 5511 , ( The Gregory Group ) in Area 2 . Any reroofing of buildings with wood shingles or wood shakes will have to have materials of Class C or better . Materials available for Class C are fiberglass shingle , metal tile , perli<te tile , pressure treated wood shingles and shakes and concrete or clay tiles . Because of the added weight , the installation of concrete or clay tile would probably require reinforcing wood trusses . ----------------------------------------------------------------- ITEM NO. COPIES TO : D . S . R . S . D . S A C Board Realtors In Roofing Area 3 approximately 50% of the roofs have wood shakes and o have composition asphalt shingles . In this area , buildings may be reroofed in kind . However, a composition asphalt shingle roof could not be replaced with wood shakes . Staff recommends that the City Council conduct a public hearing , waive the reading and adopt the ordinance . n'c^ . .. _ .. .. .,..•tl . ... ., .... ,.... ^..... .._.. .. ... .,+:1 ...J.n"L.,......).f.VU,J......l rL..,.. ..4.4{ud,.,rti.dt.t>.._.M..ei.,?�...,,ir,4 .1e_ ...1:-v r....$.....{.r.,f.. .,.,.,... t..,.i-,..
