RESOLUTION P.C. 03-9
A RESOLUTION OF THE PLANNING COMMISSION OF THE
CITY OF HERMOSA BEACH, CALIFORNIA, RECOMMENDING
AMENDING SECTION 17.22.060G, SECTION 17.22.010 AND
SECTION 17.22.060F.6 OF THE ZONING ORDINANCE TO
CHANGE THE REQUIREMENTS FOR SOUND INSULATION
FOR FLOOR/CEILING ASSEMBLIES TO A MINIMUM OF 54
STC IN ALL CASES OTHER THAN BETWEEN STACKED
DWELLING UNITS, TO RESTRICT PLUMBING IN
FLOOR/CEILING ASSEMBLIES IN STACKED UNITS AND TO
DEFINE "COMMON WALL"
The Planning Commission of the City of Hermosa Beach does hereby resolve as follows:
Section 1. The Planning Commission held a duly noticed public hearing on February 18, 2003,
to consider amending Section 17.46.010 pertaining to the allowable size and height of chimneys.
Section 2. Based on the evidence considered at the public hearing, the Planning Commission
makes the following findings:
1. The Zoning Ordinance requires an STC rating of 58 for floor/ceiling assemblies which
requires floor/ceiling assemblies to be constructed with light weight concrete.
2. Requiring a 58 STC rating for floor/ceiling assemblies for other than between floors of
stacked units imposes a hardship on builders, and is not necessary to provide good quality
sound proofing.
3. A definition for "common wall' is necessary to distinguish between walls that may allow
plumbing and walls where plumbing is prohibited.
4. Floor/ceiling assemblies cannot be sound -proofed adequately to attenuate noise generated
by plumbing, and installation of such needs to be prohibited in stacked dwelling units.
5. The subject text amendment is exempt from the requirements of the California
Environmental Quality Act (CEQA), pursuant to the general rule set forth in Section
15061(3) of the CEQA Guidelines, as there is no possibility that this modification may
have a significant effect on the environment.
Section_ 3. Based on the foregoing, the Planning Commission hereby recommends that the
Hermosa Beach Municipal Code, Title 17-Zoning, Chapter 17.22, be amended as follows:
