significant element of Poway s rural expanding earthen channels constructing

The other alternative is to construct The timing and construction of these
upstream detention basins The projects will be based on need and
detention basins are less costly can be financing
constructed at one time concrete
channels are normally constructed in
segment due to the high costs and will
save the natural creeksides of Poway
Detention basins reduce the width of the
floodplain by holding back the
floodwaters and letting them out slowly
but over a longer duration However the
primary purpose of reducing the volume
and velocity is achieved and the amount
of damage reduced
Although flooding poses the greatest
potential danger to life and property for
those residences in proximity to major
streams and channels losses from
flooding are not exclusively limited to
those areas Drainage waters that follow
tributaries and ditches often swell beyond
their channels during heavy rain storms

surrounding residents and that the uses are consistent with the policies of the Land
Use and Community Design Elements
8 In rural residential areas most uses other than agricultural and residential shall be
limited to areas with natural slopes of 10 percent or less Other uses such as hiking
and riding trails driving ranges golf courses and other recreational uses may be
considered on steeper slopes providing that they do not significantly alter the
landform Buildings and parking lots must adhere to slopes of less than 10 percent
9 The distribution of land uses should consider the health safety and welfare of the
community in regard to natural hazards
10 Public or quasi public structures schools churches hospitals shall be located in
low risk seismic or geologic hazard areas
11 Community commercial land uses that will serve the entire community or subregion
in which poway is located are encouraged along Poway Road adjacent to existing
uses of similar intensity
12 Limited neighborhood commercial activities may be located on the border of rural
residential and urban land uses
13 Mobile home park land uses shall be located in areas compatible with existing land
uses and in proximity to major roads transit commercial areas and public services
and facilities
14 New urban development projects residential areas with greater than two dwelling
units per acre du ac commercial and manufacturing shall be bounded on a
minimum of two sides by existing urban land uses and existing public facilities
15 Where a commercial area abuts a residential area the following improvements shall
be made to ensure compatibility
Structures shall be adequately set back from the residential property line to
avoid land use impacts
INCLUDES AMENDMENTS THROUGH GPA 9401 PUBLIC SAFETY 45
POWA Y COMPREHENSIVE PLAN GENERAL PLAN
An eight foot high solid masonry wall shall be constructed along the residential
property line except where it is clearly demonstrated that a shorter wall will
adequately protect the residential property
Landscaping in the form of trees shrubs and ground covers shall be planted
within an area at least five feet wide in addition to wall footings on the inside
area of the wall
16 It is the specific intent of the City that commercial land uses on Pomerado Twin
Peaks and Espola Roads not be substantially expanded beyond their present
locations
17 Public and semi public uses should be located where the use is compatible with
surrounding land uses development intensity topography and architectural style The
following provisions shall guide the location of such uses
Site should be located adjacent to a Transportation Element roadway
Public utilities should be immediately available to the site
Sites where the public semi public uses can serve as a buffer between
residential and other potentially incompatible use are particularly appropriate
18 Manufacturing uses shall be located so as not to create adverse impacts on
surrounding land uses and or the City transportation system
19 Commercial and manufacturing service land uses adjacent to residential land uses
shall include a buffer zone or noise attenuation wall to reduce outside noise levels at
the property line to 60 dBA
20 Incompatible land uses shall not be made contiguous without adequate buffering
and or setbacks Special emphasis and techniques shall be used in buffering
surrounding land uses from commercial uses In the event a question of compatibility
exists between two uses or intensities the lower intensity use shall take precedence
The City Council shall make the final determination in those areas of questionable
land use compatibility
21 Provide information on all submitted development proposals that may affect student
enrollment to the poway Unified School District PUS D for review in light of their
planning goals The City shall provide the PUSD with regular reports of building
permit activity

Floodplains and Floodways
22 Land within the 100 year floodplain should be designated for low density residential
or open space uses
23 Structures which do not conform to poway Flood Hazard Management standards must
be brought into conformance with these standards if reconstruction rebuilding or
repairing made necessary by damage will exceed SO percent of the reasonable
replacement value of the structure prior to any damage
24 Critical emergency uses hospitals fire stations police stations public administration
buildings and schools shall not be located in flood hazard areas
2S Development within the 100 year floodway is prohibited
26 Development in the 100 year floodplain may be approved if the following conditions
are met
All structures both permanent and temporary must be raised one foot above
the 100 year flood level
Information certifying the 100 year flood level must be submitted by a qualified
civil or hydrological engineer
All weather access must be provided to all developments for divisions of land
residential units commercial buildings manufacturing buildings or public
buildings
Information certifying that no upstream or downstream changes to the 100 year
floodplain will occur must be submitted by a qualified civil or hydrological
engineer
n For purposes of land division floodway areas shall not be included in the calculation
of net area
28 To prevent increased flooding within Poway all new land divisions and commercial
developments shall be reviewed to determine the feasibility of storm drainage
detention Should the project increase the storm drainage runoff by ten percent or
more the differential storm drainage runoff shall be detained to the satisfaction of the
City Engineer This does not preclude the City from requiring storm drainage
detention for projects which do not exceed a 10 percent differential increase in storm
drainage
29 No development shall be approved that would inhibit prevent or preclude the location
of proposed detention basins on Rattlesnake Creek and the north and south branches
of poway Creek as outlined in the Floodwater Detention Basin Survey dated August
