GROUNDWATER POLICY
Establishing a Policy for Developments Served by Potable Water Wells
It is the policy iof the City Council of the City of Poway to deny
division of any parcel of land which cannot be serviced by water by
an established water district, unless that division can be serviced
by an adequate supply of good quality groundwater extracted by wells
or other subsurface extraction devices.
In addition to the existing County of San Diego Health Department
requirements, it is further established that a study by a qualified
geohydrologist shall be submitted to the City as part of a proposal
for such a division of land. The groundwater study shall include:
2o
A description of the project with estimated water
usage that includes both domestic and agricultural
usage. Estimates of agricultural usage shall be
consistent with realistic assessments of the type
of division proposed, and the agricultural classi-
fication of soils encountered.
A realistic assessment of the amount of recharge
available for those uses. Recharge from both
onsite and offsite areas shall be considered, and
the relative quantity and quality from each source
stated.
5o
A realistic assessment of the property separating
it into geohydrologic zones where appropriate.
Zoning shall include, but not be limited to,
alluvial basins, zones of deeply weathered bedrock,
zoning of bedrock where fractures are anticipated
to be the major water source into areas of widely
spaced or closely spaced fractures.
Assessment of the storage capacity of the different
zones based on either evaluation of existing wells
or by drilling and testing of wells, including
observation wells and pump test data or then current
hydrotechnological techniques acceptable to the
Director of Public Services.
Ail reports shall include the data obtained during
the study, references, and conclusions as to the
total quantity of rechargeable water available
from each zone and for each proposed parcel,
unless a commonly owned water system is proposed.

Minimum lot size will be based on:
Establishing water usage for both agricultural and
domestic requirements. Domestic useage shall be
base~ upon 326,000 g~llons per dwelling unit.
2. Total water usage of geohydrologic zone.
3. Recharge of geohydrologic zone.
4. Total impact on existing uses of that specific
geohydrologic zone.
Groundwater usage for domestic purposes shall conform to the require-
ments of the City of Poway, County Health Department, County of
San Diego, and other pertinent regulatory agencies. Should conflicts
occur between the City of Poway's Groundwater Policy and other
agencies' policies, the City's policy shall prevail.
