conditions contained herein, and makes the following findings in support of these
actions:
FINDINGS
PRELIMINARY DEVELOPMENT PLAN - REZONING
1. The rezoning of the site to P -1; Planned Unit Development District is consistent
with the Town of Danville 2010 General Plan. The General Plan contains policies
that encourage clustering of development on flatter portions of properties to
preserve open space and natural features. 2010 General Plan Policies 1.07, 2.05,
and 18.02 contain such provisions, with Policies 1.07 and 18.02 specifically
identifying PUD or P -1 zoning as implementation measures. All three of these
policies are carried forward in the Danville 2030 General Plan, with Policy 18.02
being renumbered 20.02. In addition, Municipal Code section 32 -63.1b provides
that the P -1 zoning district is intended to be used for properties identified as
Special Concern Areas in the General Plan: the subject property is identified as a
Special Concern Area.
2. The project site is identified as a Special Concern Area in the General Plan. The
text for the Special Concern Area of the Magee Ranch property (on page 58 of the
2010 General Plan) includes the following relevant direction:
• The Plan describes Diablo Road in this area as retaining "the flavor of an
ambling country road. The Town strongly supports retention of this
character and protection of the views and vistas from the road."
• "[P]roposals which transfer the allowable number of homes to the least
sensitive and obtrusive parts of the site are encouraged."
• "As on the other large undeveloped hillside sites in Danville, protection of
scenic slopes and ridgelines is imperative. Despite the A -2 (General
Agricultural) zoning on much of the site, subdivision of this Special
Concern Area into five -acre 'ranchette' sites similar to those in the
Tassajara Lane /Sherburne Hills area is strongly discouraged. Such
development would require grading and road construction that could
substantially diminish the visual qualities of the area. On the other hand,
transferring allowable densities to a limited number of areas within the
ranch would enable the bulk of the site to be set aside as permanent open
PAGE 5 OF RESOLUTION NO. 60 -2013
space. This would also provide opportunities to establish park and trail
connections and to preserve wildlife corridors between this area and the
Sycamore Valley Open Space.
P -1 zoning is the only zoning designation that permits this clustering of potential
development, without creation of 5 -acre "ranchettes," which the Special Concern
Area language specifically discourages on the property.
3. The Town further finds that the rezoning for residential development is within
the maximum permitted density under the existing General Plan land use
designations on the property, which include Single Family -Low Density, Rural
Residential, Agricultural and General Open Space.
4. The uses authorized or proposed in the land use district are compatible within
the district and to uses authorized in adjacent districts. The proposed infill
housing is an efficient development pattern consistent with surrounding
residential subdivisions and will add to existing infrastructure that services the
adjacent single family residential uses.
FINAL DEVELOPMENT PLAN - MAJOR SUBDIVISION
1. The proposed subdivision is in substantial conformance with the goals and
policies of the 2010 General Plan, including the requirements of Measure S. The
Town's 2010 General Plan recognizes the site as an important site that merits
specific direction for its development. As such, the site is designated as one of 14
Special Concern Areas within the General Plan. The Special Concern Area
language includes the following provisions, which are addressed through the
proposed project:
• The Plan describes Diablo Road in this area as retaining "the flavor of an
ambling country road. The Town strongly supports retention of this
character and protection of the views and vistas from the road." The
revised project removes all lots with direct driveway access to Diablo
Road and, with the exception of the main driveway into the project,
reduces the visibility of the project from Diablo Road.
• The Plan provides that "[P]roposals which transfer the allowable number
of homes to the least sensitive and obtrusive parts of the site are
encouraged." The project would transfer all but three lots to the area of
the site which is the least environmentally sensitive. The clustering of
homes would comply with this directive.
• The Plan provides that "As on the other large undeveloped hillside sites in
Danville, protection of scenic slopes and ridgelines is imperative. Despite
PAGE 6 OF RESOLUTION NO. 60-2013
the A -2 (General Agricultural) zoning on much of the site, subdivision of
this Special Concern Area into five -acre "ranchette" sites similar to those
in the Tassajara Lane /Sherburne Hills area is strongly discouraged. Such
development would require grading and road construction that could
substantially diminish the visual qualities of the area. On the other hand,
transferring allowable densities to a limited number of areas within the
ranch would enable the bulk of the site to be set aside as permanent open
space. This would also provide opportunities to establish park and trail
connections and to preserve wildlife corridors between this area and the
Sycamore Valley Open Space." The project, through the use of P -1 zoning
to cluster the permitted development, would avoid creation of "ranchette"
sites, would limit grading and road construction and substantially
preserve the visual quality of the area. The clustering of the project would
also permanently preserve 372 acres, or approximately 91% of the site as
open space, which would include trail connections to the Sycamore Valley
Open Space and preserve wildlife corridors through the site.
2. The design of the proposed subdivision is in conformance with the P -1; PIanned
Unit Development District since the subject P -1; Planned Unit Development
District is customized to the subject Development Plan. The P -1; Planned Unit
Development District is an appropriate zoning designation for infill projects and
lands designated as Special Concern Areas in the General Plan. Additional
detailed findings regarding P -1 zoning consistency can be found under
Preliminary Development Plan - Rezoning above.
3. The design of the subdivision and the type of associated improvements will not
likely cause serious public health problems, because water and sanitary facilities
services will be available to the new parcels.
4. The site of the subdivision is physically suitable for the proposed density of
development. The proposed development of 69 lots on the 410 +/- acre site falls
within the allowable maximum density range of up to 78 units, consistent with
the site's Danville 2010 General Plan land use designations of Residential - Single
Family - Low Density, Rural Residential, Agricultural and General Open Space.
With respect to density on the portions of the site designated as "Agricultural" in
the 2010 General Plan, the General Plan provides the following:
"Because properties with this designation are bound by Williamson Act contract
to remain in agricultural uses, a density range is not applicable. In the event that
Williamson Act contracts are not renewed, continued agricultural use is
PAGE 7 OF RESOLUTION NO. 60 -2013
encouraged and the underlying zoning density (one unit per 20 acres or one unit
per five acres) would apply upon the contract expiration."
The portions of the site designated as Agricultural are no longer bound by
Williamson Act contract. In such situations, the Town's practice (and that of
Contra Costa County, prior to the Town's incorporation in 1982) was to zone
lands to A -4; Agricultural Preserve District (20 acre minimum) upon execution of
a Williamson Act contract, regardless of the size or prior zoning of the property.
The purpose of this A -4; Agricultural Preserve District zoning designation is to
show that the property is under a Williamson Act contract. For example, the
Town rezoned the 'Sorel" property (APN 218 - 090 -031) from P -1; Planned Unit
Development District to A -4; Agricultural Preserve District upon execution of a
Williamson Act contract, despite the entire parcel being only 17 acres. Under the
A -4; Agricultural Preserve District zoning designation one home per 20 acres is
allowed.
Upon expiration of a Williamson Act contract, the General Plan dictates that the
Town apply the "underlying" zoning, which has been the zoning in effect prior
to entering into the contract. This reflects the intent to place the property in the
position it held prior to entering into the contract, neither increasing nor
decreasing the property's development potential. This practice was previously
applied by the Town with respect to Assessors Parcels 202 - 100 -017, -018, and -019
on the subject property. In February 1986, the Town approved a Williamson Act
contract for these parcels and at the same time adopted an ordinance rezoning
them from A -2; General Agricultural District to A -4; Agricultural Preserve
District. In March 1988, after discovery that the contract had never been properly
executed, the property owner requested, and the Town approved, an ordinance
rezoning the property back to the prior designation of A -2; General Agricultural
District. The property owner in this case did not apply to rezone the property
after the Williamson Act contract expired. However, in determining potential
density for purposes of this application, the Town used the underlying zoning of
A -2; General Agricultural District (with the corresponding maximum
development density of one unit per five acres) as provided for in the General
Plan and consistent with prior applications, including the Elworthy Ranch
project approved by the Town in 2008 under the approval granted for
Preliminary Development Plan - Rezoning request PUD 2005 -02.
5. The design of the proposed subdivision and improvements are not likely to
cause substantial environmental damage or subsequently injure fish or wildlife
or their habitat. The Environmental Impact Report prepared for the project
found that, with implementation of recommended mitigation measures, the
PAGE 8 OF RESOLUTION NO. 60-2013
project would have no significant negative impacts on the wildlife on site,
including California Red Legged Frogs, wetlands, trees and plant life.
6. The design of the proposed subdivision and proposed improvements will not
conflict with easements, acquired by the public at large, for access through or use
of property within the proposed subdivision. There are currently no existing
public easements for access through or use of the subdivision. Through project
conditions of approval, the subdivision will offer new easements for public
access.
7. The project will not cause on -site flooding or add to existing downstream
flooding as detailed in the Hydraulic Report prepared for the project by ENGEO,
Inc. and as concurred with by the Contra Costa County Flood Control and Water
Conservation District.
TREE REMOVAL PERMIT
The project as proposed would preserve 262 trees of more than 300 surveyed trees and
many other trees located throughout the site, and remove 56 trees. Of the 56 trees to be
removed, 12 are designated as Town - protected trees under the Town's Tree
Preservation Ordinance.
The findings below address only the 12 trees designated as protected under the Town's
Tree Preservation Ordinance. The EIR for the project analyzes the potential
environmental impacts of removing all trees, whether or not they are designated as
protected.
1. Necessity. The primary reason for removal of the 56 trees, including 12 Town -
protected trees, is that preservation of those trees would be inconsistent with the
proposed residential development of the property, including the creation of a
new roadway to access the main project area, including a new creek crossing, to
be located east of Jillian Way, and the widening of the Diablo Road /Green Valley
Road /McCauley Road intersection to the south to improve the function of that
intersection.
2. Erosion /surface water flow. Removal of the 12 Town - protected trees and 56
total trees would not cause significant soil erosion or cause a significant
diversion or increase in the flow of surface water.
3. Visual effects. With respect to other trees in the area, the project site contains a
significant number of additional trees, including Town - protected Oak trees that
PAGE 9 OF RESOLUTION NO. 60-2013
would not be removed for the project. In addition, the project proponent will be
required to replace all Town - protected trees to be removed with approved
species "of a cumulative number and diameter necessary to equal the diameter of
the tree(s) which are approved for removal" in accordance with the Town's Tree
Preservation Ordinance. Tree replacement will be conducted in accordance with
the Town's requirements, including planting a mixture of small and large box
trees to meet the cumulative diameter number of the removed trees. The project
proponent will also be required to replace all non - ordinance -size trees (i.e., trees
less than 10 inches in diameter for single -trunk trees or less than 20 inches in
diameter for multi -trunk trees) at a replacement -to- removal ratio of 1:1.
Removal of the 56 trees, including 12 Town - protected trees, would not
significantly affect off -site shade or adversely affect privacy between properties
due to the site's topography, the other trees that would remain, and the locations
of the trees in relation to other properties.

trash /recycling receptacles, doggy -bag dispensers, entry gates, and
benches shall be provided as required by the Town according to current
design standards. Maintenance of the trail improvements shall be
provided by the project Homeowner's Association and /or the GHAD.
The Town will have the responsibility for the future construction of the
extension of the public trail from the EVA west along the south side of
Diablo Road, as part of a future Capital Improvement Project. The exact
design/ alignment of the trail and construction timing will be determined
by the Town at a future date.
PAGE 18 OF RESOLUTION NO. 60-2013
8. The applicant shall dedicate a pedestrian access easement to the East Bay
Regional Park District ( EBRPD) which links Diablo Road with Sycamore
Valley to the south. The easement shall be a minimum width of 25'wide

referenced under Condition of Approval A.l.a., above. The exact
alignment of the trail shall be subject to review and approval by the Town
and the EBRPD prior to recordation of the final map.
9. The existing Green Valley Creek culverts along the developments frontage
with Diablo Road require the following improvement measures to assure
a properly functioning drainage course:
a. At Clydesdale Drive there exists a double 10' -wide by 6' -high
reinforced concrete box culvert. The applicant shall remove the
ranch - constructed cattle gate (corrugated sheet metal) that
currently obstructs flows through one of the two adjacent culverts,
and shall remove accumulated sediment and debris from within
the culvert.

installations.
E. BIOLOGICAL
1. The project proponent shall implement the folloziling measures during
construction activities in or along East Branch Green Valley Creek to avoid take
of individual CRLF:
a. Prior to the start of construction, the project proponent shall retain a
qualified biologist to train all construction personnel regarding habitat
sensitivity, identification of special status species, and required practices.
b. Prior to the start of construction, the project proponent shall retain a
qualified biologist to conduct pre - construction surveys to ensure that
CRLF are absent from the construction area. If CRLF are present, a
qualified biologist possessing all necessary permits shall relocate them or
they shall be allowed to move out of the construction area on their own.
C. Immediately following the pre - construction surveys and a determination
that CRLF are not present in the construction zone, the construction zone
PAGE 22 OF RESOLUTION NO. 60-2013
shall be cleared and silt fencing erected and maintained around
construction zones to prevent CRLF from moving into these areas.
d. The project proponent shall retain a qualified biological monitor to be
present onsite during times of construction within the riparian habitat of
East Branch Green Valley Creek to ensure no CRLF are harmed, injured,
or killed during project buildout.
2. The project would impact approximately 0.3 acres of moderate - quality riparian
habitat resulting from construction of the vehicular bridges across East Branch
Green Valley Creek. The project shall replace the lost value of this impact by
restoring the impacted riparian habitat at a minimum 1:1 replacement -to -loss
ratio. (Final mitigation amounts will be based on actual impacts to be determined
during the design phase.) This shall be accomplished by restoring riparian habitat
at the four following locations:
a. The existing wet crossing and asphalt near the panhandle (i.e., where the
new bridge is to be constructed) shall be removed. The silt and sediment
buildup behind and adjacent to the wet crossing and asphalt shall also be
removed and the creek bed shall be lowered to restore the natural flow of
this portion of the creek.
b. The existing crossing from San Andreas Drive shall be removed and the
creek restored in this area.
The two existing cattle grates on Magee West near the existing culverts
shall be removed. One of these is causing sediment build up and adversely
impacting the creek. The natural flow of this channel shall be restored back
to its original condition prior to the original installation of the grates.
d. The riparian corridor along the East Branch of Green Valley Creek will be
enhanced with suitable planting and placement of riparian vegetation along
the proposed trail on Magee East, Approximately 2 acres along East
Branch Green Valley Creek between the creek and the trail is available to
accommodate the minimum 0.3 acres of riparian enhancement plantings.
The enhancement area shall be planted with native species appropriate for
the corridor.
3. The project would impact approximately 0.5 acres of jurisdictional waters that are
of a degraded quality and marginal value for the CRLF. The project shall replace
the lost functions and value of this impact to aquatic habitats at a minimum of 1:1
replacement -to -loss acreage ratio. The final mitigation amounts will be based on
actual impacts to be determined during the design phase. Habitat replacement via
PAGE 23 OF RESOLUTION NO. 60-2013
creation of and /or enhancements to existing maters shall occur onsite. Onsite
lands proposed to be preserved as open space are within the same watershed as the
offsite detention basin known to support breeding CRLF and are expected to fu11y
accommodate creation of and /or enhancements to aquatic habitats that mould be of
substantially higher value to CRLF than the impacted waters. Compensation for
impacts to jurisdictional waters to benefit the CRLF will include all of the
aforementioned components along with improving the wetland character of the
onsite stock pond and enhancing the associated riparian habitat between the stock
pond and the detention basin. (Refer also to mitigation measures 4.4 -13 and 4.4-
14 below for impacts to jurisdictional waters.)
4. The project proposes to preserve approximately 372 acres of tine project site as
open space. Areas to be preserved would be placed under a conservation easement
or deed restriction to prohibit construction and preserve conservation value. The
project proposes to create a geologic hazard abatement district (GHAD) to provide
suitable funding for management and long -term maintenance of the site. Lapland
habitats shall be managed via a long -term management plan to maintain the
quality of the habitat for the movement and dispersal of CRLF. Prior to
construction, the project proponent shall retain a qualified biologist to prepare an
open space management plan for the explicit purpose of managing and
monitoring the proposed open space area. This plan shall be submitted to the
Town of Danville for review and approval prior to issuance of grading permits.
At a minimum this plan shall include the following components:
a. Identifi/ the location of the restoration efforts for replacing jurisdictional
waters and riparian habitats. The replacement ratio for both habitats will
be at a minimum of a 1:1 ratio.
b. Identifij the approaches to be used, including the extent that the onsite
stock pond be expanded, reconfiguring of the pond bottom and increase in
depth, and providing evidence that sufficient water budget exist for any
proposed enhancement.
C. Identify a suitable planting regime for restoring wetland and riparian
habitats.
d. Identifij success criteria for monitoring both the wetland and riparian
habitats that are consistent with similar habitats regionally.
Monitor restored wetland habitats for at least Five years and restored
riparian habitats for 10 years.
f. Define and identifij the GHAD maintenance and management activities to
manage the opera space habitats to meet the stated goals of support habitat
PAGE 24 OF RESOLUTION NO. 60-2013
characteristics suitable for the CRLF. This would include suitable fencing
so as to control access, limited cattle grazing or other procedures to
manage grass height and forage production at levels that benefit the
CRLF, and removal of trash.
g. Define the financial mechanism for the GRAD to manage the open
space into perpetuity.
5. Prior to the start of construction, the project proponent shall retain a qualified
biologist to train construction personnel regarding habitat sensitivity,
identification of special status species, and required practices.
6. Prior to the start of construction within the East Branch Green Valley Creek
riparian area, the project proponent shall retain a qualified biologist to conduct
pre - construction surveys to ensure that western pond turtles are absent from the
construction area. If western pond turtles are present, a qualified biologist
possessing all necessary permits shall be retained to relocate them.
7. If western pond turtles are found to be absent from the construction zone,
immediately following the pre - construction surveys the project proponent shall
clear the construction zone and install /maintain silt fencing around the
construction zone to prevent western pond turtles from entering these areas.
8. During construction within the East Branch Green Valley Creek riparian area,
the project proponent shall retain a biological monitor to be present onsite during
times of construction to ensure that turtles are not harmed, injured, or killed.
9. To the maximum extent practicable, the project proponent shall remove trees
during the non - breeding season (September 1 through Januanf 31). if it is not
possible to avoid tree removal and associated disturbances during the breeding
season (February 1 through August 31), the project proponent shall retain a
qualified biologist to conduct a pre- construction survey for tree - nesting raptors
and other tree - or ground - nesting migratory birds in all trees or other areas of
potential nesting habitat within the construction footprint and 250 feet of the
footprint, if such disturbance would occur during the breeding season. This
surrey shall be conducted no more than 14 days prior to the initiation of
demolition /construction activities during the early part of the breeding season
(February through April) and no more than 30 days prior to the initiation of these
activities during the late part of the breeding season (May through August). If
nesting raptors or migratory birds are detected on the site during the survey, a
suitable construction free buffer shall be established around all active nests. The
precise dimension of the buffer (a minimum of 150 feet up to a maximum of 250
feet) shall be determined at that time and may vary depending on location and
PAGE 25 OF RESOLUTION NO. 60-2013
species. Buffers shall remain in place for the duration of the breeding season or
until it has been confirmed by a qualified biologist that all chicks have fledged and
are independent of their parents. Pre - construction surveys during the non -
breeding season are not necessary, as the birds are expected to abandon their
roosts during construction activities.
10. In order to avoid impacts to active burrowing owl nests, the project proponent
shall retain a qualified biologist to conduct pre- construction surveys for
burrowing ozals within the construction footprint and zoithin 250 feet of the
footprint no more than 30 days prior to the onset of ground disturbance. These
surveys shall be conducted in a manner consistent with the CDFG's burrowing
OZPI survey methods (CDFG 2012b). If pre- construction surveys determine that
burrowing owls occupy the site during the non - breeding season (September 1
through January 31), then a passive relocation effort (e.g., blocking burrows with
one -way doors and leaving them in place for a minimum of three days) may be
used to ensure that the owls are not harmed or injured during construction.
Once it has been determined that owls have vacated the site, the burrows can be
collapsed, and ground disturbance can proceed. If burrowing owls are detected
within the construction footprint or immediately adjacent lands (i.e., within 250
feet of the footprint) during the breeding season (February 1 through August 31),
a construction free buffer of 250 feet shall be established around all active owl
nests. The buffer area should be enclosed with temporary fencing, and
construction equipment and workers may not enter the enclosed setback areas.
Buffers must remain in place for the duration of the breeding season or until it
has been confirmed by a qualified biologist that all chicks have fledged and are
independent of their parents. After the breeding season, passive relocation of any
remaining owls may take place as described above.
11. Pre- construction surveys conducted for burrowing owls shall also be used to
determine the presence or absence of badgers in the development footprint. If an
active badger den is identified during pre - construction surveys within or
immediately adjacent to the construction envelope, the project contractor shall
establish a construction free buffer around the den of up to 300 feet or a distance
specified by the resource agencies (i.e., CDFG). Because badgers are known to use
multiple burrows in a breeding burrow complex, the project contractor shall
retain a biological monitor during construction activities to ensure the buffer is
adequate to avoid direct impacts to individuals or nest abandonment. The
monitor shall be present onsite until it is determined that young are of an
independent age and construction activities would not harm individual badgers.
Once it has been determined that badgers have vacated the site, the burrows can
be collapsed or excavated, and ground disturbance can proceed.
PAGE 26 OF RESOLUTION NO. 60-2013
12. The project proponent shall replace wetland and riparian habitat at a 1:1
replacement -to -loss ratio. It is expected that all compensation measures can be
accommodated within the 372 acres of the site proposed as open space. Prior to
issuance of a grading permit, the project proponent shall retain a qualified
biologist to prepare an onsite habitat mitigation and monitoring plan (HMMP)
that includes both an aquatic habitat restoration plan and a riparian habitat
restoration plan. The HMMP would specifically address the wetland and riparian
habitats and is separate from the Open Space Management Plan identified in
Mitigation 4.44, although there may be some overlap. The HMMP shall include
the following components, at a minimum:
a. Define the location of all restoration /creation activities
b. Provide evidence of a suitable water budget to support any created
wetland and riparian habitats,
C. Identifij the species, amount, and location of plants to be installed,
d. Identifij the time of year for planting and method for supplemental
watering during the establishment period,
Identify the monitoring period, which should be not less than 5 years for
wetland restoration and not less than 10 years for riparian restoration,
defines success criteria that will be required for the wetland restoration to
be deemed a success;
f. Identify adaptive management procedures that include (but are not limited
to) measures to address colonization by invasive species, unexpected lack
of water, excessive foraging of installed wetland plants by native wildlife,
and similar,
g. Define management and maintenance activities (weeding of invasives,
providing for supplemental water, repair of water delivery systems) of the
proposed GHAD; and
h. Provide for assurance in funding the monitoring and ensuring that the
created wetland and riparian habitats fall within lands to be preserved and
managed into perpetuity. Confirm that the proposed GHAD will meet
these responsibilities.
PAGE 27 OF RESOLUTION NO. 60 -2013
13. The project proponent shall comply with all state and federal regulations related
to construction work that will impact aquatic habitats occurring on the site.
Prior to construction, the project proponent shall obtain a Section 404 Clean
Water Act permit from the USACE, Section 401 Water Quality Certification
from the RWQCB, and /or Section 1600 Streambed Alteration Agreement from
the CDFG, and submit proof of such documentation to the Town of Danville.
14. Prior to issuance of a grading permit, a tree preservation plan shall be prepared
for all trees to be retained that identifies all protection and mitigation measures
to be taken and includes the tree preservation guidelines by HortScience in their
tree report(s). These measures shall remain in place for the duration of
construction activities at the project site.
15. Upon completion of construction, the project proponent shall replace all
ordinance -size trees to be removed with approved species "of a cumulative
number and diameter necessary to equal the diameter of the tree(s) which are
approved for removal" in accordance with the Town's tree ordinance. Tree
removal shall be conducted in accordance with the Town's requirements,
including planting a mixture of small and large box trees to meet the cumulative
diameter number of the removed trees. The project proponent shall replace all
non - ordinance -size trees (i.e., trees less than 10 inches in diameter for single -
trunk trees or less than 20 inches in diameter for multi -trunk trees) at a
replacement -to- removal ratio of 1:1. To the maximum extent practicable, all
native trees that are removed shalt be replaced with like species. All non - native
trees that are removed shall be replaced with species that are known to occur
naturally within similar habitats in the region.
16. Prior to construction, the project proponent shall retain a qualified arborist to
develop a monitoring plan for replacement trees (outside the riparian habitat)
and submit it to the Town of Danville during the permit process. The basic
components of the monitoring plan shall include final success criteria, specific
performance criteria, monitoring methods, data analysis, monitoring schedule,
contingency /remedial measures, and reporting requirements.
17. If the Town determines that the improvements to the Diablo Road /Green Valley
Road intersection are required, the project shall implement Mitigation Measures
4.4 -14 through 4.4 -16 above, as applicable.
F. GRADING
* 1. Any grading on adjacent properties will require prior written approval of
those property owners affected.
PAGE 28 OF RESOLUTION NO. 60-2013
2. At least one week prior to commencement of grading, the applicant shall
post the site and mail to the owners of property within 300 feet of the
exterior boundary of the project site, to the homeowner associations of
nearby residential projects and to the Town of Danville Development
Services Department, a notice that construction work will commence. The
notice shall include a list of contact persons with name, title, phone
number and area of responsibility. The person responsible for maintaining
the list shall be included. The list shall be kept current at all times and
shall consist of persons with authority to initiate corrective action in their
area of responsibility. The names of individuals responsible for dust, noise

3. Development shall be completed in compliance with a detailed soils
report and the construction grading plans prepared for this project. The
engineering recommendations outlined in the project specific soils report
shall be incorporated into the design of this project. The report shall
include specific recommendations for foundation design of the proposed
buildings and shall be subject to review and approval by the Town's
Engineering and Planning Divisions.
4. Where soils or geologic conditions encountered in grading operations are
different from that anticipated in the soil report, a revised soils report
shall be submitted for review and approval by the City Engineer. It shall
be accompanied by an engineering and geological opinion as to the safety
of the site from settlement and seismic activity.
5. In order to avoid mater quality impacts, a Storm Water Pollution Prevention
Plan (SWPPP) shall be prepared for the site preparation, construction, and post-
construction periods. The SWPPP shall incorporate best management practices
consistent with the requirements of the National Pollution Discharge Elimination
System (NPDES) Municipal Stormzoater permit (No. CAS612008). The project
proponent shall obtain a NPDES General Construction Permit and prepare the
SWPPP in accordance znith all legal requirements, prior to the issuance of a
