GROUNDWATER POLICY
Establishing a Policy for Developments Served by Potable Water Wells
It is the policy of 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:
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, the agricultural classification
of soils encountered, and proposed limitations imposed
as part of covenants, deeds or equivalent documents tied
to the proposed parcels.
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.
Recharge estimates shall include estimates of all
consumptive uses existing on the system.
A realistic assessment of the property separating
it into geohydrologic zones where appropriate.
Zoning shall include, but notlbe limited to,
alluvial basins, zones of deeply weathered bedrock,
classifications of bedrock where fractures are
anticipated to be the major water source into areas
of widely spaced or closely spaced fractures.
4. 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, in which
case the total safe yield shall apply.
Minimum lot size will be based on:
Establishing water usage for both agricultural and
domestic requirements. Domestic usage shall be
based upon 326,000 gallons per dwelling unit.
2. Total water usage estimates for each proposed parcel.
3. Recharge of geohydrologic zones.
4. Total impact on existing uses,,both within and outside the
proposed division, on the groundwater system.
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.
