A RESOLUTION ESTABLISHING A LIST OF UNREINFORCED MASONRY
BUILDINGS BY GROUPING CLASSIFICATION FOR THE PURPOSE OF SETTING A
TIME FRAME FOR STRENGTHENING AS OUTLINED IN THE URM BUILDING
ORDINANCE
WHEREAS, the City of Petaluma acknowledges the unreinforced masonry buildings within
its limits and the need to strengthen them within a defined time period;
NOW, THEREFORE BE IT RESOLVED:
I. All buildings now on our URM Building List be divided into four groups. Group I
Buildings being of potentially high risk and in need of strengthening first. Group II,
II and IV to follow.
II. The time frame established to strengthen these URM Buildings are detailed in
Petaluma Ordinance No. 1882 ,Section 17.34.110:
Group I 10 Years Parapets 10 Years
Group II 15 Years Parapets 12 Years
Group III 20 Years Parapets 12 Years
Group IV 25 Years Parapets 12 Years
III. Explanation of the Petaluma URM Building Classification process:
The UMB Citizens Advisory Committee considered the following factors to
establish retrofit priority of UMB's identified in Petaluma:
Occupancy - to establish the relative risk of a particular building to its occupants,
assuming higher occupancy equals higher potential risk.
Calculated by dividing the total square footage of each use identified in the building,
by the corresponding load factor assigned to each use by the Uniform Building code.
These Occupancy Factors were used to classify the buildings into five Groups:
92-48
1
Rcs. No . ...:........ ...............:.. N.C.S.
i
Group 1 = > 300
Group 2 = 100-299
Group 3 = 50-99
Group 4 = 20-49
Group 5 = < 20
Geographic - to establish the relative risk of a particular building to its immediate
surroundings, assuming a total failure outward.
Calculated as the sum of three rating factors each on a scale of one to three, a rating
of one indicating highest relative risk, two indicating moderate relative risk, and
three indicating low relative risk to people other than occupants:
Physical Height -considered in equivalent stories, assuming a taller building
is a higher relative risk:
Rating 1 =three stories
Rating 2 =two stories
Rating 3 =one story
Adjacency -relationship to immediately adjacent buildings, assuming a taller
building next to a shorter building is a higher relative risk:
Rating 1 = full story taller than adjacent building
Rating 2 = partial story taller than adjacent building, or full or
partial story taller than itself
Rating 3 = same relative height as adjacent building
Pedestrian Proximity -relationship of the building to pedestrian activity, assuming
that immediate adjacency to areas with a higher frequency of pedestrians is a higher
relative risk:
Rating 1 =elevation at sidewalk in Central Business District
Rating 2 =elevation at sidewalk outside Central Business District
Rating 3 =elevation setback off sidewalk
The Petaluma. class is the sum of the Occupancy Group number and the Geographic
Risk Rating. The Retrofit or Risk Group is derived from the Petaluma Class rating
number as follows:
2
Group I =Petaluma Class score 4 - 7
Group II =Petaluma Class score 8
Group III =Petaluma Class score 9
Group IV =Petaluma class score 10 - 14
