|
Contamination from spills and parking lot runoff:
|
•
|
Indirect impacts from water quality degradation:
| ||
|
(1.)
|
Grading should be restricted to the period from April 15 through
October 15 to minimize the indirect impacts of erosion and sedimentation
on biological resources unless a specific erosion control plan and
program have been approved by the City Engineer and Director of Community
Development and all necessary erosion control devices are in place.
The grading of the upland areas should be limited to late summer and
early fall to avoid conflicts with the California Gnatcatcher breeding
season or as directed by the U.S. Fish & Wildlife Service.
| |
|
(2.)
|
Temporary desiltation basins and standard construction sedimentation
control measures should be implemented to prevent siltation of Encinitas
Creek. Exposed slopes should be immediately reseeded with a suitable
erosion control ground cover after completion of grading. Long-term
sedimentation and water quality impacts should be addressed by ensuring
slope stability, adequate slope drainage systems, and effective revegetation
of exposed slopes.
| |
|
(3.)
|
An erosion control plan approved by the City Engineer should
be implemented.
| |
•
|
Wetlands impacts:
| ||
|
(1.)
|
Impacts to wetlands shall be mitigated through the enhancement and creation of 4.4 acres of wetlands. Measures shall include the enhancement of 3.2 acres of wetlands and the creation of 0.7 acres of new wetlands as specified in Section D, Wetlands Program of Chapter III. In addition, a periodically maintained nuisance water treatment wetland totaling 0.5 acres will also contribute to the mitigation of wetland impacts. Grading for restoration and restoration planting are to be closely monitored to ensure that no substantial damage occurs to existing wetlands to be preserved and that wetland restoration is successfully completed as specified in plan documents.
| |
|
(2.)
|
Maintenance and monitoring of the mitigation measures for 5
years. Monitoring must be conducted at 3, 6, 9, 12, 24, 36, 48 and
60 months. Monitoring reports must be prepared within 30 days of each
monitoring, and annual reports must be provided to the City of Encinitas,
U.S. Army Corps of Engineers, USF&WS and the CDF&G.
| |
|
(3.)
|
Removal of non-native species from the existing wetland.
| |
|
(4.)
|
There shall be a minimum 50-foot biological buffer. A 150-foot
planning buffer shall incorporate the 50-foot biological buffer and
50-100 feet of unstructured paved area in the parking lot.
| |
|
(5.)
|
Release of the performance bond posted with the City of Encinitas
must be contingent upon successful completion of the mitigation plan,
as determined jointly by the U.S. Army Corps, USF&WS, CDF&G
and the City of Encinitas.
| |
|
(6.)
|
Installation of oil interceptors in the paved areas to collect urban runoff and the creation of 0.5 acres of nuisance water treatment wetlands as defined in Chapter II.
| |
|
(7.)
|
Installation of fencing to separate the Home Improvement Center
from the wetlands area.
| |
|
(8.)
|
Wetlands in the nuisance water detention/purification pond and
associated silt and grease traps must be cleaned through pumping and
removal of trapped materials, and not by flushing of the system. At
a minimum, traps must be cleaned in early October and March of each
year. The wetland treatment basins must be maintained by partial removal
of sediments and plant materials on a biennial basis, with work being
conducted in March following the winter rainy period and prior to
initiation of spring riparian bird nesting season. No more than 50%
of the plant material is to be removed at any given time. This must
be continued for the life of the project.
| |
|
(9.)
|
Initially, the project applicant will dredge the area beneath,
and within 20 feet upstream of, the El Camino Real bridge structure.
It will be the responsibility of the City of Encinitas to monitor
the sedimentation under the bridge and dredge the area as necessary
to maintain an elevation of 72 feet.
| |
|
(10.)
|
The monitoring of the revegetation efforts should be both qualitative
and quantitative. Qualitative assessments should be made at the time
of each report to indicate whether the revegetation is, in general,
successful (i.e., if the plants are becoming established and healthy).
If the monitoring indicates that any of the revegetation effort is
not progressing, the consulting biologist will need to identify potential
reasons for the lack of progress and make recommendations for any
changes that should occur in the mitigation plan.
| |

|
Coastal Mixed Chaparral and sensitive plant species impacts
- To mitigate potential impacts to the Southern Mixed Chaparral community
and to the Coast Scrub Oak, one of the following three options should
be implemented to the satisfaction of the Encinitas Community Development
Director:
| ||
|
(1.)
|
Implementation of the cribwall alternative instead of the proposed
project.
| |
|
(2.)
|
An intensive planting program to restore the Southern Mixed
Chaparral, including containerized planting of pretreated plants and
some seeding (not all hydroseeding).
| |
|
(3.)
|
The purchase and preservation, in a natural state, of good quality
Southern Mixed Chaparral off-site.
| |
•
|
Brush control impacts - The thinning of the native vegetation
for fire protection at the base of the slope behind the Home Improvement
Center should be accomplished in the following manner:
| ||
|
(1.)
|
Thinning must be limited to hand clearing of Chamise and Black
Sage.
| |
|
(2.)
|
Selective hand pruning must be used to thin and reduce lower
vegetative portions of the following shrubs: Coast Scrub Oak, Toyon,
Lemonade-berry and Laurel-leaf Sumac.
| |
|
(3.)
|
The following species must be retained in an unaltered state:
Del Mar Manzanita, Coast White Lilac, Chaparral Coffeeberry, Mohave
Yucca and Ramona Lilac.
| |
|
(4.)
|
Annual species and low-growing perennials must remain unless
they are exotic elements to the Chaparral.
| |
|
(5.)
|
Thinning must be limited to cutting of material, and no soil
disturbance is to occur which may exacerbate erosion of the slope
areas.
| |
|
(6.)
|
Zones 3 and 4, including non-irrigated and irrigated planting
areas, should not contain plants which are known to escape from cultivation.
In particular, various ice plants, Ngaio, Pampas Grass, Fountain Grass
and similar invasive plants should be prohibited from use within these
zones.
| |
•
|
California Gnatcatcher habitat - Because the California Gnatcatcher
has been federally listed as a threatened species, mitigation for
potential impacts to California Gnatcatcher habitat will be determined
by the U.S. Fish & Wildlife Service. Two alternatives will be
considered by the Service:
| ||
|
(1.)
|
On-site Mitigation Alternative - Under this alternative portions
of Planning Areas 1 and 2 and all of Planning Area 3 will be dedicated
as biological open space easements. The residential development area
of Planning Area 2 will be reduced and less than 17 lots will be created.
This alternative will provide a link between the steep slope vegetation
and the wetlands on-site, will provide the regionally needed southern
biological linkage to Green Valley, and will tend to address multi-species
enhancement through the protection of additional vegetation in Planning
Area 2.
In order to ensure the biological integrity of the Gnatcatcher
habitat under this alternative, no access to Planning Area 4 will
be allowed across the biological open space easement required in Planning
Area 3. Since there will be no direct access to the southerly portion
of Planning Area 4 under this scenario, the disturbed habitat of this
area may be revegetated to serve as wetland mitigation for future
development of the northerly portion of Planning Area 4 along Olivenhain
Road. Under this scenario the southern portion of Planning Area 4
may also be proposed for subdivision from the northerly, developable
portion of the planning area. The southerly portion may then be acquired
by a developer requiring off-site wetland mitigation for a non-related
project.
| |
|
(2.)
|
Off-site Mitigation Alternative - This alternative addresses
mitigation through acquisition and preservation of off-site land that
is suitable long-term Gnatcatcher habitat. Off-site mitigation would
translate into more defensible Gnatcatcher habitat which would be
less susceptible to the secondary impacts associated with the urban
environs of Encinitas. The off-site land acquisition should meet the
following criteria:
| |
|
|
(a.)
|
Minimum size: 16 acres
|
|
|
(b.)
|
Presence of existing Gnatcatcher population
|
|
|
(c.)
|
Must connect to other habitat
|
|
|
(d.)
|
Must be compatible with existing and planned land uses
|
|
|
(e.)
|
Should be within 5 miles of the SPA
|
|
|
(f.)
|
Must be acceptable to the U.S. Fish & Wildlife Service
|
•
|
Earth settlement/liquefaction - The potential for settlement
of the alluvium is recommended to be mitigated in one of two ways:
|
•
|
Long-term impacts on existing regional traffic problems:
Project applicants should be required to contribute, on a fair-share
basis, to regional traffic improvements.
| |
•
|
Cumulative impacts on nearby roads and intersections until roads
are improved:
| |
|
(1.)
|
The project applicant shall relinquish access rights to El Camino
Real except for the three proposed entrances.
|
|
(2.)
|
Improve El Camino Real to a one-half graded ROW width of 68
feet with 58 feet of asphaltic concrete pavement over approved base
with Portland cement concrete curb, gutter, bike lane and sidewalk,
with curb at 58 feet from the centerline, and provide a raised median
for the full length of frontage on El Camino Real except for the main
entrance intersection.
|
|
(3.)
|
Contribute to the widening of Olivenhain Road, which includes
improvement of the El Camino Real/Olivenhain Road intersection.
|
•
|
Short-term cumulative impacts on Encinitas Boulevard intersections
at I-5 and El Camino Real - It is recommended that the project applicants
contribute funding on a fair-share basis toward the following future
City improvements:
| |
|
(1.)
|
Construction of an eastbound right-turn lane on Encinitas Boulevard
at El Camino Real.
|
|
(2.)
|
The widening of the I-5 exit ramps at Encinitas Boulevard to
provide two left-turn lanes and two right-turn lanes, and by widening
Encinitas Boulevard to provide three eastbound and westbound through
lanes.
|
•
|
Potential safety hazards related to access and internal circulation:
| |
|
(1.)
|
Provide patterned Bomanite pads along the main driveway in front
of the home improvement center building. These special treatment areas
should be located at the end of each parking aisle adjacent to the
store front. The special paving treatments should end 4 to 6 feet
south of the parking lot landscape islands and should not include
the customer pick-up lane.
|
|
(2.)
|
The same Bomanite paving treatment described in #1 above should
be used at the main entrance near El Camino Real.
|
|
(3.)
|
A minimum of three striped crosswalks should be added in front
of the home improvement center along the main entry driveway on smooth
asphalt paving. The striping should be prominent and extend to the
Bomanite paving areas on each side. The Bomanite should not extend
entirely across the driveway on the north side so that a smooth walkway
will be available for customers with carts.
|
|
(4.)
|
The main entry must be at least 48 feet wide.

and the wetlands on-site, will provide the regionally needed southern
biological linkage to Green Valley, and will tend to address multi-species
enhancement through the protection of additional vegetation in Planning
Area 2.
In order to ensure the biological integrity of the Gnatcatcher
habitat under this alternative, no access to Planning Area 4 will
be allowed across the biological open space easement required in Planning
Area 3. Since there will be no direct access to the southerly portion
of Planning Area 4 under this scenario, the disturbed habitat of this
area may be revegetated to serve as wetland mitigation for future
development of the northerly portion of Planning Area 4 along Olivenhain
Road. Under this scenario the southern portion of Planning Area 4
may also be proposed for subdivision from the northerly, developable
portion of the planning area. The southerly portion may then be acquired
by a developer requiring offsite wetland mitigation for a non-related
project.

Off-site Mitigation Alternative - This alternative addresses
mitigation through acquisition and preservation of off-site land that
is suitable longterm Gnatcatcher habitat. Off-site mitigation would
translate into more defensible Gnatcatcher habitat which would be
less susceptible to the secondary impacts associated with the urban
environs of Encinitas. The off-site land acquisition should meet the
following criteria:
| |
|
|
(a.)
|
Minimum size: 16 acres
|
|
|
(b.)
|
Presence of existing Gnatcatcher population
|
|
|
(c.)
|
Must connect to other habitat
|
|
|
(d.)
|
Must be compatible with existing and planned land uses
|
|
|
(e.)
|
Should be within 5 miles of the SPA
|
|
|
(f.)
|
Must be acceptable to the U.S. Fish & Wildlife Service

Indirect impacts from water quality degradation:
| |
|
(1.)
|
Grading should be restricted to the period from April 15 through
October 15 to minimize the indirect impacts of erosion and sedimentation
on biological resources unless a specific erosion control plan and
program have been approved by the City Engineer and Director of Community
Development and all necessary erosion control devices are in place.
The grading of the upland areas should be limited to late summer and
early fall to avoid conflicts with the California Gnatcatcher breeding
season or as directed by the U.S. Fish & Wildlife Service.
|
|
(2.)
|
Temporary desiltation basins and standard construction sedimentation
control measures should be implemented to prevent siltation of Encinitas
Creek. Exposed slopes should be immediately reseeded with a suitable
erosion control ground cover after completion of grading. Long-term
sedimentation and water quality impacts should be addressed by ensuring
slope stability, adequate slope drainage systems, and effective revegetation
of exposed slopes.
|
|
(3.)
|
An erosion control plan approved by the City Engineer should
be implemented.
|
•
|
Wetlands impacts:
| |
|
(1.)
|
The area south of Encinitas Creek in Planning Area 4 indicated
as developable in the Specific Plan includes approximately 0.2-acre
of wetlands. The northern limit of the developable area should be
scaled back, at a minimum, to the wetland boundary.
|
|
(2.)
|
The designated developable area south of Encinitas Creek includes
approximately 1.3 acres of steep slopes. It is recommended that the
uses of the steep slopes be restricted to those which do not require
grading or exposure of the soil.
|
|
(3.)
|
A nuisance water treatment wetland similar to that designed
for Planning Area 1 should be constructed and maintained for any development
in Planning Area 4. It should be designed when development is proposed.
|
|
(4.)
|
The degraded wetlands should be used for buffering the existing
wetlands.
|
|
(5.)
|
If the developable areas are not reduced as recommended in #1
and #2 above, mitigation for the loss of wetlands within Planning
Area 4 may require off-site mitigation.

A covenant shall be recorded in the office of the County Recorder
agreeing to the above condition by current and all future property
owners. The Wetlands Enhancement open space in Planning Area 1 shall
be designated as a biological open space easement on the Final Map.
Temporary construction easements shall be permitted as approved by
the City Engineer within these open spaces for the implementation
of utility installation and for required grading and the implementation
of revegetation programs.
