WHEREAS, the City Council determines that the project is consistent with the General
Plan, as stated in Resolution 1,0, ^adopting a General Plan Amendment for this project;
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF ROHNERT
PARK DOES RESOLVE, DETERMINE AND ORDER AS FOLLOWS:
Section L That the above recitations are true and correct.
Section 2. Findings. The City Council, in approving Specific Plan PL2003 -002SP
(Specific Plan Application) makes the following findings, makes the following findings; to wit:
Development Area Plan PL2003 -002
Specific Plan PL2003 -002SP
1. The specific plan or specific plan amendment is consistent with the city's general plan
Criteria Satisfied. The specific plan would implement the General Plan's goals for the
University District Specific Plan Area in that it would increase the City's existing housing
stock and proportion of units that are affordable to very low -, low -, and moderate - income
households. It would also develop the property with a pedestrian- oriented, mixed use
community that is consistent with the goals and objectives of the General Plan for this area.
2. The specific plan or specific plan amendment will not adversely affect the public health and
safety or result in incompatible land uses.
Criteria Satisfied. The specific plan would direct the development of the area with a
pedestrian- oriented, mixed -use community that is intended to encourage walking and
cycling, thereby reducing the use of the automobile and resulting in a beneficial impact. The
project has been designed so that it would be effectively buffered from adjacent uses and the
scenic corridor along Petaluma Hill Road. The proposed commercial development and
recreational facilities would benefit existing residents in the area, as well as new residents of
the project.
3. The specific plan or specific plan amendment provides the framework to phase and pace
growth within the specific plan area so as to ensure completion of all necessary public
facilities concurrently with completion of the specific plan; or, alternately, a statement of
public policy consideration can be adopted and /or an exception granted in accordance with
general plan policies GM -10, GM -11, and GM -12.
Criteria Satisfied. The project will be phased as shown in the proposed specific plan. The
timing of the construction of public facilities will be paced to meet the needs of the
development and is called out in the project's Development Agreement.
4. The specific plan or specific plan amendment identifies adequate financing mechanisms for
the infrastructure and public facilities required to support the development.
Criteria Satisfied. The project will be subject to the Public Facilities Financing Plan fees to
help fund off -site improvements. On -site improvements shall be the responsibility of the
developer.
5. The proposed specific plan is consistent with the planning and prezoning designation
provided for the specific plan area, pursuant to Government Code Sections 65300 and
65859, or alternatively functions as prezoning for the unincorporated territory.
Criteria Satisfied. The site will be prezoned "Specific Plan District (SP)," which would be
consistent with the direction of the City's General Plan.
Section 3. Environmental Clearance. The City adopted CEQA findings, a statement of
overriding considerations, and a mitigation and monitoring plan in connection with the General
Plan Amendment adopted in Resolutiongooto- l -qz , in connection with the University District
Specific Plan Project ( "Project "). The City is now granting an approval subordinate to the
General Plan Amendment, for all or a portion of the Project addressed in that prior Resolution.
In connection with that subordinate approval, the City finds that each of the mitigation measures
2
applicable to the subordinate approval, and which was found in Resolution 2ceb -lyx to avoid or
reduce potentially significant impacts, has been imposed as a condition of approval of that
subordinate approval. In addition, the City finds that there have been no substantial changes in
the aspects of the Project reflected in the subordinate approval, the surrounding circumstances, or
the balance between the benefits of the aspects of the Project reflected in the subordinate
approval and the acceptability of its significant and unavoidable impacts. There are no
substantial changes proposed in the Project which will require major revisions of the previous
EIR due to the involvement of new significant environmental effects or a substantial increase in
the severity of previously identified significant effects; no substantial changes with respect to the
circumstances under which the project is undertaken which will require major revisions of the
previous EIR due to the involvement of new significant environmental effects or a substantial
increase in the severity of previously identified significant effects; and no new information of
substantial importance, which was not known and could not have been known with the exercise
of reasonable diligence at the time the previous EIR was certified as complete. Accordingly, no
supplemental or subsequent EIR is required or appropriate.
NOW THEREFORE BE IT RESOLVED, that the City Council does hereby approve
Application No. PL2003- 002SP: application for a Specific Plan for property located on each side
of Hinebaugh Creek, east of the current City limits, south of Keiser Avenue, west of Petaluma
Hill Road, and north of Copeland Creek (APN 045- 253 -007, 045- 253 -009 through —012, a,
portion of 045- 253 -018, 045- 262 -001 through -004, 047 -131 -019, and 047 -131 -024 through -
027), subject to the following conditions:
1. The following shall be reflected in the Final Specific Plan document:
a. The revised tables and figures dated April 7, 2006 and titled "University District
Specific Plan Development Agreement Modifications" shall be used.
b. A final list of the green building measures to be incorporated in the project, which
is subject to Staff review and approval.
c. The Specific Plan shall be amended to include provisions to ensure that tentative
subdivision maps for properties within the Specific Plan Area be conditioned
upon water conservation measures designed to ensure conformance with the
consumptive use calculations provided in a letter by John Olaf Nelson Water
Resources Management dated April 13, 2006.
d. Prior to development within the Abu - Halawa, Gee, and CRPUSD properties, the
project proponent for that development will retain a qualified wetland ecologist to
conduct a wetlands evaluation of the proposed development area to ensure that the
area does not support potentially jurisdictional wetlands. If wetlands are present
and will be filled, the project proponent for that development will develop a
wetland mitigation plan includes a minimum 1:1 replacement to offset the loss of
wetlands and habitat function. If the wetlands could be considered jurisdictional
by the U.S. Army Corps of Engineers, then a wetland delineation will be
conducted and the results submitted to the Corps.
e. Prior to development within on the CRPUSD, GEE and Abu - Halawa portions of
the specific plan area, the project proponent for that project will retain a botanist
to conduct a blooming- period survey of the CRPUSC, Gee and Abu - Halawa
3
portions of the study area for special -study plant species listed in table 3.4 -2 of
the Final Environmental Impact Report (FEIR) for this project. The appropriate
survey period is during late April to early May. Survey methods will be
consistent with DFG Guidelines for assessing the effects of proposed
developments on rare and endangered plants (California department of Fish and
Game 2000) and as listed in Mitigation Measure 13I0-8a of the FEIR.
f. Prior to development within the CRPUSD, GEE and Abu - Halawa portions of the
specific plan area, the project proponents for those properties shall contact the
U.S. Fish and Wildlife Service to determine whether protocol -level surveys for
California tiger salamander are warranted, per Mitigation Measure 13I0-10a of the
FEIR for this project.
g. Should the structures located on the Abu - Halawa site prove to be historical
resources, the mitigation presented in Mitigation Measure C -3a of the FEIR for
this project shall apply.
h. A survey of potential archaeological sites on the CRPUSD, GEE and Abu - Halawa
portions of the specific plan area shall be required prior to development of those
properties, as directed by Mitigation Measure C -4a of the FEIR for this project.
i. The applicant shall fund the design and construction of all facilities associated
with the water tank, including the tank, road, and utilities, in accordance with the
recommendations of the geotechnical report for the site, as contained in Appendix
"K" of the FEIR for this project.

Subject: Submittal of Information for Net Consumptive Water Use Impact
Determinations Required Pursuant to City of Rohnert Park Resolution No.
2004 -95
Dear Mr. Jenkins:
This letter -report is submitted on behalf of Brookfield Homes LLC for the University
District Specific Plan.
Pursuant to the Resolution 2004 -95, entitled A Resolution of the City Council of Rohnert
Park Implementing Requirements Imposed on Specific Plan Areas Outside the City's
1999 Boundaries (Resolution), the following information and calculations are submitted
for the University District Specific Plan (UDSP). Section references refer to the sections
contained in the resolution.
Definitions set forth in the Resolution:
Potable Water Demand is the gross demand of a proposed project (before any Potable
Water Conservation Practices or Water Use Offsets. (Section 4.b. L)
Potable Water Conservation Practices are defined as on -site water conservation
equipment and practices, including use of recycled, water that reduces the projected
potable water consumption of a project and that can be implemented and completed with
the project. (Section 4.b. a.)
Potable Water Use Offsets are defined as being water conservation equipment, practices
or programs that are funded, constructed, installed or implemented be a Project and that
offset the amount of potable water consumed by that Project, including use of recycled
water, that are applied outside of the project area ( "off- site "), but which reduce demand
on the City's water system for potable water, or, the funding, construction or
implementation of facilities or practices in any location that increases recharge to the
groundwater supplies available to the City's municipal wells: all of which can be
implemented and completed with the Project. (Section 4.b.a.)
Net Consumptive Use (NCU) Impact is the amount of Potable Water Demand of a Project
less reductions for (1) Water Conservation Practices and (2) Potable Water Use Offsets
that the City Engineer determines will be acceptable, feasible and consistent with the City
water conservation program. (Section 4.b.a.)
Average Annual Groundwater Pumping Rate of 2.3 mgd is the projected pumping rate
from the City's municipal wells for the year estimated to be the Project's buildout year.
(Section 4.b.a.)
Buildout year, for the purposes of the Resolution, is defined as that point in the future
when 80% of the commercial and residential development has been constructed and
occupied.
Required Calculations. and Information
Potable Water Demand - Section 4.b.1.
The UDSP is comprised of a total 1,645 residential units, plus 126 second units, for a
total of 1,771 dwelling units (DU's); up to 175,000 sq -ft of commercial building area;
and 21 acres of public parks and private recreation areas, and 64 acres of open space,
wetland areas, creek and creek buffer areas and structural buffer areas. A breakdown of
UDSP land uses and customer categories is contained in attachments NCU -1 and NCU -2
respectively. The resulting Potable Water Demand for the UDSP is shown in Attachment
NCU -3 and amounts to 584 ac-ft per year (afa) at full buildout. Attachment NCU -4
shows projected demand over the period of time.
Potable Water Conservation Practices — Section 4.b.2.
On -site Potable Water Conservation Practices proposed are shown on Attachment NCU -
5 and consist of:
• Low flush toilets (1.6 gpf), low flow shower heads (2.5 gpm), faucet aerators (2.2
gpm) (These are required by the Environmental Policy Act (EPAct)
• High Efficiency Cloths Washers (Water Factor < 6.0)
• ET Controllers (Single family residential sites that have permeable area > 2,500
sq -ft
• Submetering MF DU's (includes submetering of 110 apartment DU's)
• Commercial Buildings — Low flush toilets and flush valves (1.6 gpf), low flow
urinals (1.Ogpf), low flow showerheads (2.5 gpm), low flow faucets (2.2 gpm).
These are devices required by EPAct. Also, as applicable - depending on
commercial site use and feasibility, the list of conservation measures shown on
attachment NCU -6 will be required.)
• ET controllers in parks, private recreation areas and other large irrigation areas
served by irrigation only meters.
Attachment NCU -5 shows the unit and extended savings for each of these practices.
Detailed descriptions of these water conservation practices, unit savings, documentation
of savings, and water conservation calculations are contained in the Zero Foot Print
Report (see reference at end of this letter).
Total savings from Potable Water Conservation Practices is estimated to be 110 afa.
On -site Recycled Water Use (Section 4.b.3.)
Attachment NCU -7 contains a breakdown of landscape areas (both turf and non -turf) that
can be irrigated with recycled water, unit water duties and projected monthly and annual
demand. Non -turf areas are to be planted with Xeriscape plants that are served by low
head drip and micro -spray systems. Unit duties include commonly excepted crop .
coefficients and values for irrigation efficiency appropriate for urban landscape irrigation.
Details on lot sizes, irrigable area, turf and non -turf landscape areas, evapotranspiration
(ET), effective rainfall, crop coefficients, irrigation efficiency and other data, calculations
and documentation are contained in the Zero Foot Print Report (see reference at end of
this letter). Total recycled water demand is 144 afa.
Water Use Offsets — Section 4.b.4.
Given the major efforts proposed on -site, no off -site water conservation or recycled use is
proposed.
Net Consumptive Water Use — Section 4.b.5.
_ As seen in attachment NCU -3, the gross water demand for the UDSP is 584 afa (521,215
gpd). Dividing by 1,645 DU's results in a net potable water demand of 317 gpd/DU.
The NCU for the UDSP is calculated and shown in attaclunent NCU -8 and amounts to
330 afa (294,800 gpd). Dividing by 1,645 DU's results in a net potable water demand of
179 gpd /DU. This is a reduction in demand of 43 %.
If recycled water is ignored the NCU is 474 afa (423,185 gpd) which equates to 257
gpd/DU. This is a reduction in demand of 19 %.
Please note, to facilitate comparisons, that attachment NCU -8 also shows the demand
projection prepared by Winzler and Kelly Engineers for the City's Water Supply
Assessment, January 2005. Also provided for comparison purposes are attachment NCU -
9 which contains a comparison of unit rates by customer category and attachment NCU -
10 which shows a comparison for residential customer categories of unit rates "before"
any conservation or recycling vs. "after ".
Buildout — Section 4.b.6
UDSP buildout (using the 80% definition contained in the policy) is calculated
graphically as shown on attachment NCU -11. First occupancy is planned in year 2007
and "buildout" is planned three years later in 2010.
Does the UDSP Contribute to the City's Exceeding the Average Annual
Groundwater Pumping Rate of 2.3 mgd? — Sections 4.c. and 4.d.
The City of Rohnert Park's Water Supply Assessment demonstrates, based on the
demand projections contained therein, that the City would not exceed the 2.3 mgd
groundwater pumping rate. From inspection of attachment NCU -8, Potable Water
Demand of the UDSP would exceed the WSA projection by 2.3% if onsite conservation
measures were not employed. Application of the proposed Potable Water Conservation
Practices reduces demand to 17% below the WSA projection. Adding recycled water use
proposed reduces the demand to 35% below the WSA projection (note that the WSA
assumed UDSP would use recycled water on parrs and other large irrigation areas). The
projected NCU for the UDSP provides a very large margin of safety. Even if the
projected savings were 100% overestimated, the projected UDSP NCU would be below
projections of same contained in the WSA. Clearly, the conclusion is that the UDSP Net
Potable Water Demand does not contribute to the City exceeding an average annual
pumping rate of 2.3 mgd.
How ongoing Water Conservation Practices and Recycled Water Use will be
maintained — Section 5.
Conditions, Covenants and Restrictions (CC &Rs) are written rules, limitations and
restrictions on use, mutually agreed to by all owners of homes in a subdivision or
condominium complex. CC &Rs may limit size and placement of homes, exterior colors,
pets, ages of residents, use of barbecues and other conduct to protect the quiet enjoyment
of the various residents. CC &Rs are enforced by the homeowner association (HOA) or by
individual owners who can bring lawsuits against violators. CC &Rs are permanent or
"run with the land" so future owners are bound to the same rules. It is through properly
and fairly drawn -up CC &Rs and enforcement by HOA's (including condo associations,
townhouse /home associations, common interest developments, etc.) that maintenance of
the conservation measures proposed for the UDSP will be accomplished.
It is planned that the CC &Rs for a given ownership, in addition to their other
responsibilities, will address and cover the following requirements:
1 Maintenance /replacement of landscaping in common areas of MF units.
2. Maintenance /replacement of landscaping in front yards of SF homes served
with recycled water.
3. Maintenance and operation of ET controllers serving irrigation only meters
and meters serving recycled water in front yards of SF homes.
4. Payment of monthly service fees for ET controllers and serve as point of
contact for dealing with any problems concerning controllers.
5. Maintenance, repair and replace recycled water irrigation systems located
downstream of the meter in the front yard of SF homes and common irrigation
areas where recycled water is used. Work to comply with the Health and
Safety Code, and Titles 22 and 17 of the California Code of Regulations.
6. Maintenance of an inventory of toilet flapper valves compatible with the low -
flush toilets installed within a given HOA area and periodic notices informing
homeowners that these are available free to those experiencing malfunctioning
or leaking flappers. The initial inventory and information on replacements
will be supplied to the HOA by the developer. (Research has shown that the
majority of residential leaks are due to worn out flappers. Flappers have a
useful life of about 5 years.)
7. In the case of apartment units, responsibility for reading meters and rendering
sub -bills and maintaining /replacing meters and other equipment required for
submetering. Renter "consumer protections" patterned after those described
in the Zero Foot Print Report, Dec. 2004, pg 12 to be employed.
Regards metering and billing for recycled water, it is assumed the Santa Rosa
Subregional Water Reclamation System (SRSWRS) will be responsible for operation and
maintenance of all off -tract facilities, in -track mains and in -tract distribution lines up to
and including the recycled water meter. The cost of this service will be covered by
SRSWRS's charge for recycled water service which will be billed directly to the HOA, or
in the case of recycled water served to UDSP "irrigation only accounts ", to the
association, owner or party responsible for the property for which irrigation service is
provided. Currently it is the policy of the SRSWRS to charge 75% of local potable water
system rates after a 3 -year ramp -up period, which, based on the City of Rohnert Park's
FY 2003 -04 potable water rate amounts to $1.31 per 1,000 gallons. It is further assumed
that recycled water meters installed will be specified to be the same as the wireless
automatic meter reading (AMR) meters installed by the City for SF customers and that
the SRSWRS will work out an arrangement with and compensate the City for reading and
billing recycled water service. The added time it would take to read AMR recycled water
meters in the UDSP area when fully built out is estimated to be less than 20 minutes per
billing cycle.
This concludes this submittal. We of course stand ready to answer any questions you
may have.
Sincerely,
John Olaf Nelson

Notes:
(1) Served by turf sprinkler irrigation systems
(2) Mainly water conserving shrubs, ground covers and trees. Served by bubblers, drip
and micro -spray irrigation
systems.
(3) Sprinkler systems efficiencies are much lower for residential size turf parcels.
(4) 10 year average, 1991 - 2000, from the California Irrigation Mgt. Info. System, taking effective rainfall into account. as
reported in City of Santa Rosa's Incremental Recycled Water Program (IRWP), Draft EIR, Tech, Memo 4 (Ref. 2)
(5) KL is the landscape coefficient: 0.80 for cool season grasses, and 0.50 for drought tolerant and Mediterranean plants.
(6) Based on analysis of City of Santa Rosa's water irrigation meters over a six year period (1995 - 2000), (Ref. 2)
