TO: Chair and Planning Commission October 26, 2021
SUBJECT: Resolution No. 2021-06, approving Minor Subdivision request MS 852-
2019 allowing the subdivision of an existing 0.78-acre parcel into two
single-family residential lots at a site located at 2434 Tassajara Lane
DESCRIPTION
This application is a request to subdivide a 0.78-acre parcel, located at 2434 Tassajara
Lane, into two single-family residential lots. A residence is currently under construction
on proposed Parcel B. The site contains Sycamore Valley Creek which runs through the
southern portion of the parcel. There are no Town-protected trees on the subject property
affected by this proposal.
EVALUATION/ DISCUSSION
Conformance with General Plan and Zoning District
The site has a General Plan Land Use Designation of Residential – Single Family – Low
Density (1-3 Units Per Acre). The parcel is zoned P-1; Planned Unit Development with R-
10; Single Family Residential District (minimum 10,000 square foot parcel size) zoning
standards. At 15,148 and 19,148 square feet, the proposed lots meet the minimum
required lot size. The proposed subdivision also complies with all the minimum required
lot dimension requirements.
C.3. Stormwater Pollution Control
In compliance with the Town’s Stormwater Management and Discharge Control
Ordinance, this subdivision would be subject to compliance with the Town’s C.3
stormwater pollution control requirements as found in the Stormwater Control Plan. One
stormwater treatment facility is proposed for each lot. The C.3. facilities would be subject
to a maintenance agreement with the Town.
Parcel Development
As recommended through conditions of approval, the future development of single-
family residences on proposed Parcel A would be subject to review by the Design Review
Board under a separate Development Plan application. Each residence would be required
to connect to public water and sewer services.
2434 Tassajara Lane 2 October 26, 2021
Creek Trail
Consistent with the requirements of the Town’s Parks, Recreation and Arts Master Plan,
this development would be required to dedicate a public trail easement, and construct an
eight-foot wide asphalt trail, along Sycamore Creek. This trail section is part of a long
term plan to provide a continuous pedestrian trail along Sycamore Creek.
ENVIRONMENTAL REVIEW
The project has been found to have less than significant environmental impacts with the
incorporation of mitigation measures under the California Environmental Quality Act
(CEQA). As a result, a Draft Mitigated Negative Declaration of Environmental
Significance has been prepared for this project.
PUBLIC CONTACT
Public notice of the October 26, 2021, hearing was mailed to property owners within 750
feet and posted online. A total of 87 notices were mailed to surrounding property owners.

Danville, CA Planning Dept.
Attn: David Crompton
During the past week, we have been corresponding with Riley Anderson-Barrett regarding the building
proposal “MS852-2019 2434 Tassajara Lane Lot Split”. In the course of these emails, she has told us that
the Valley Oak which is a Heritage tree will have a protection plan in place. She also clarified that two of
the three existing redwoods would be cut down because an arborist, hired by the builder, reported that
the redwoods were over crowded. (I am sure there are also over crowed Sequoia in our California
forests, but they are not cut down.) We also understand that fighting the driveway coming off of
Mcneil Lane is a losing battle because the property at 2434 Tassajara Lane has always had access to the
lane.
Riley also told us that there is a plan in place to hold the builder responsible for repairing and repaving
Mcneil Lane to address the damage the construction trucks will cause. That is not to say how many
times our property at 37 Mcneil Lane will be inaccessible during the building process.
Riley also said that the driveway is going to be in the northeast corner of the property. As I am sure you
are aware from viewing plot maps, our property extends over the lane in front of our house. This brings
us to another point: the oleander bushes which currently run along the lane. Our property extends into
these bushes . Riley said that at this time, there has been no discussion about whether they are going to
be left in place. Certainly since our property does extend there, they should not be touched in front of
our property at 37 Mcneil Lane.
As I explained to Riley, all the owners on Mcneil Lane take all trash, recycle, and compost barrels down
the lane so the trash truck does not put wear and tear on Mcneil Lane. As she said, hopefully the new
owners will cooperate with this. Who knows?
We had planned on attending the Public Hearing on Oct 26, 2021. Because we did not receive the notice
about this hearing until today, Oct 15, we will not be able to attend as we have planned a trip that
takes us out of the country during this time. We are asking that this letter be submitted into evidence in
the Planning Committee for this matter.
Thank you,
Leslie & Patrick Chambers

DRAFT MITIGATED NEGATIVE DECLARATION OF ENVIRONMENTAL
SIGNIFICANCE
LEAD AGENCY: Town of Danville -- (Riley Anderson-Barrett)
NAME OF PROJECT: MS 852-2019 – 2434 Tassajara Lane Lot Split
PROJECT DESCRIPTION: Minor Subdivision requests to subdivide a 0.78-acre
parcel, located at 2434 Tassajara Lane, into two single-
family residential lots with one home under
construction on Parcel B. The site contains the
Sycamore Valley Creek which runs through the
southern portion of both parcels. There are no Town-
protected trees on the subject property affected by
this proposal.
ENVIRONMENTAL EFFECTS/MITIGATION MEASURES:
1.BIOLOGICAL RESOURCES:Will the Project:
a)Have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or
special status species in local or regional plans, policies, or regulations, or
by the California Department of Fish and Game or U.S. Fish and Wildlife
Service? Less than significant with mitigation incorporated/Less Than
Significant Impact. According to a biological resources analysis report
prepared by Monk & Associates Environmental Consultants, special
status species, such as the California red-legged frog, are unlikely to be
impacted by this project. No California red-legged frogs were observed
during a one day survey conducted by Monk & Associates. The project
site is not designated as a “Critical Habitat.” There are no known
occurrences of the California Red-Legged Frog in Sycamore Creek with its
nearest Critical Habitat found 2.1 miles north of the project site. The
project site does not provide any habitat for the Alameda Whipsnake with
ATTACHMENT D
October 11, 2021
Page 2
its nearest Critical Habitat 1.9 north of the project site. The project site
does not provide habitat for any other special-status species and no
impacts to special-status species are expected from house construction. All
raptors and other nesting migratory birds are protected under the
Migratory Bird Treaty Act and their eggs and young are protected under
California Fish and Game Codes.
MITIGATION MEASURE 1: If tree removal must take place between February 1st and August
31st,, preconstruction nesting surveys shall be conducted by a qualified biologist to ensure no
nesting birds would be impacted by the trees’ removal. If birds are determined to be nesting in
the tree(s) slated for removal or in a nearby tree that could be disturbed by noise, a non-
disturbance buffer shall be demarcated around the nest tree and no disturbance shall occur
within the buffer zone until the present birds have finished nesting. Once nesting is completed
and the young birds are flying freely, the non-disturbance buffer may be removed.
b)Have a substantial adverse effect on any riparian habitat or other sensitive
natural community identified in local or regional plans, policies,
regulations or by the California Department of Fish and Game or US Fish
and Wildlife Service? Less than significant with mitigation
incorporated/Less Than Significant Impact. According to a biological
resources analysis report prepared by Monk & Associates Environmental
Consultants, the proposed project would not result in any direct impacts
to the drainage feature or any other seasonal wetlands within the project
site. The project will not result in any direct impacts to this draining
feature or any other seasonal wetlands. No structures are proposed within
this setback. No impacts are anticipated to the drainage feature, or its
associated vegetation.
MITIGATION MEASURE 2: Wildlife exclusion fencing would be installed around the
perimeter of the drainage channel and around the perimeter of the project site to ensure that
ground dwelling wildlife species are precluded from accessing the construction area.
MITIGATION MEASURE 3: The trail will be placed a minimum of 10 feet back from the top-
of-bank to ensure protection of the riparian vegetation.
MITIGATION MEASURE 4: No lights will be installed along the trail that may impact
migrating wildlife along the creek.
October 11, 2021
Page 3
c)Have a substantial adverse effect on federally protected wetlands as
defined by Section 404 of the Clean Water Act (including, but not limited
to, marsh, vernal pool, coastal, etc.) through direct removal, filling,
hydrological interruption, or other means? Less than significant with
mitigation incorporated/Less Than Significant Impact. According to a
biological resources analysis report prepared by Monk & Associates
Environmental Consultants, the proposed project would not result in any
direct impacts to the drainage feature or any other seasonal wetlands
within the project site.
MITIGATION MEASURE 5: Stormwater and surface water runoff will be directed into the
Town’s storm drain system. Straw wattles and crushed rocks will encircle all storm inlets. Self-
treating and self-retaining drainage areas are spread out throughout the site. Silt fences will
prevent mobilized sediments and other construction debris from entering the adjacent creek
corridor.
MITIGATION MEASURE 6: A Best Management Practices plan will be prepared and
submitted to ensure no inadvertent siltation impacts to Sycamore Creek while the project is
under construction.
MITIGATION MEASURE 7: The proposed trail will have a 10-foot setback from Sycamore
Creek’s top-of-bank.
d)Interfere substantially with the movement of any native resident or
migratory fish or wildlife species or with established native resident or
migratory wildlife corridors, or impede the use of native wildlife nursery
sites? Less than significant with mitigation incorporated/Less Than
Significant Impact. According to a biological resources analysis report
prepared by Monk & Associates Environmental Consultants, there is not
any aquatic habitat that would provide breeding habitat for aquatic
species. All raptors and other nesting migratory birds are protected under
the Migratory Bird Treaty Act and their eggs and young are protected
under California Fish and Game Codes.
MITIGATION MEASURE 8: Wildlife exclusion fencing would be installed around the
October 11, 2021
Page 4
perimeter of the drainage channel and around the perimeter of the project site to ensure that
ground dwelling wildlife species are precluded from accessing the construction area.
MITIGATION MEASURE 9: If tree removal must take place between February 1st and August
31st,, preconstruction nesting surveys shall be conducted by a qualified biologist to ensure no
nesting birds would be impacted by the trees’ removal. If birds are determined to be nesting in
the tree(s) slated for removal or in a nearby tree that could be disturbed by noise, a non-
disturbance buffer shall be demarcated around the nest tree and no disturbance shall occur
within the buffer zone until the present birds have finished nesting. Once nesting is completed
and the young birds are flying freely, the non-disturbance buffer may be removed.
e)Conflict with any local policies or ordinances protecting biological
resources, such as a tree preservation policy or ordinance? Less than
Significant with Mitigation Incorporated. There are forty-one trees on
the site. Eight non-protected trees are proposed to be removed.
MITIGATION MEASURE 10: The applicant shall be responsible for new tree plantings at a
1:1 for all trees to be removed. Replacement trees shall be of a species listed as a protected tree
under the Town’s Tree Preservation Ordinance.
2.NOISE:Would the project result in:
f)A substantial temporary or periodic increase in ambient noise levels in the
project vicinity above levels existing without the project? Less than
Significant with Mitigation Incorporated. Noise levels will temporarily
be increased due to noise associated with the construction of the project.
The noise impact will be less than significant given required standard
mitigation measures.
MITIGATION MEASURE 11: The applicant shall require their contractors and
subcontractors to fit all internal combustion engines with mufflers, which are in good condition, and to locate stationary noise-generating equipment as far away from existing residences as
feasible.
Construction activity shall be restricted to the period between the weekday hours of 7:30 a.m. to
5:30 p.m. (Mondays through Fridays), unless otherwise approved in writing by the City
October 11, 2021
Page 5
Engineer for general construction activity and the Chief Building Official for building
construction activity. Prior to any construction work on the site, including grading, the
applicant shall install a minimum 3’ x 3’ sign at the project entry which specifies the allowable
construction work days and hours, and lists the name and contact person for the overall project
manager and all contractors and sub-contractors working on the job.
DETERMINATION: Based upon the above identified mitigation measures, no
significant environmental impacts are anticipated to be
associated with the subject project. A Draft Mitigated
Negative Declaration of Environmental Significance has
been prepared.
The Initial Study was prepared by the Planning Department, Town of Danville. Copies
of the Initial Study may be obtained at the Town offices located at 510 La Gonda Way,
Danville, California 94526.
