SUBJECT: PROJECT REPORT AND CONDITIONS,
JAMES CANYON ESTATES, CT 98-20/CDP 98-90/HDP 98-22
The Engineering Department has completed its review of the subject project. The Engineering
Department is recommending that the project be approved, subject to the following conditions:
General
38. Prior to issuance of any building permit, the developer shall comply with the requirements of the
City's anti-graffiti program for wall treatments if and when such a program is formerly
established by the City.
39. There shall be one final subdivision map recorded for this project.
42. NOTE: Unless specifically stated in the condition, all of the following
engineering conditions upon the approval of this proposed major
subdivision must be met prior to approval of a final map.
44. All concrete terrace drains shall be maintained by the homeowner's association (if on commonly
owned property) or the individual property owner (if on an individually owned lot). An
appropriately worded statement clearly identifying the responsibility shall be placed in the
CC&R's (if maintained by the Association) and on the Final Map.
45. The developer shall defend, indemnify and hold harmless the City and its agents, officers, and
employees from any claim, action or proceeding against the City or its agents, officers, or
employees to attack, set aside, void or null an approval of the City, the Planning Commission or
City Engineer which has been brought against the City within the time period provided for by
Section 66499.37 of the Subdivision Map Act.
46. Prior to hauling dirt or construction materials to or from any proposed construction site within
this project, the developer shall submit to and receive approval from the City Engineer for the
proposed haul route. The developer shall comply with all conditions and requirements the City
Engineer may impose with regards to the hauling operation.
47. Rain gutters must be provided to convey roof drainage to an approved drainage course or street

48. The developer shall provide for sight distance corridors at all street intersections in accordance
with Engineering Standards and shall record the following statement on the Final Map (and in
the CC&R's).
"No structure, fence, wall, tree, shrub, sign, or other object over 30 inches above the
street level may be placed or permitted to encroach within the area identified as a sight
distance corridor in accordance with City Standard Public Street-Design Criteria, Section
8.B.3. The underlying property owner shall maintain this condition."
Fees/Agreements
50. The developer shall pay all current fees and deposits required.
51. The owner of the subject property shall execute an agreement holding the City harmless
regarding drainage across the adjacent property.
55. The owner shall execute a hold harmless agreement for geologic failure.
56. Prior to approval of any grading or building permits for this project, the owner shall give written
consent to the annexation of the area shown within the boundaries of the subdivision plan into
the existing City of Carlsbad Street Lighting and Landscaping District No. 1 on a form provided
by the City.
Grading
58. Based upon a review of the proposed grading and the grading quantities shown on the tentative
map, a grading permit for this project appears to be required. The developer must submit and
receive approval for grading plans in accordance with City codes and standards prior to issuance
of a building permit for the project.
59. Prior to the issuance of a grading permit or building permit, whichever occurs first, the developer
shall submit proof that a Notice of Intention has been submitted to the State Water Resources
Control Board.
60. Upon completion of grading, the developer shall ensure that an "as-graded" geologic plan is
submitted to the City Engineer. The plan shall clearly show all the geology as exposed by the
grading operation, all geologic corrective measures as actually constructed and must be based on
a contour map which represents both the pre and post site grading. This plan shall be signed by
both the soils engineer and the engineering geologist. The plan shall be prepared on a 24" x 36"
mylar or similar drafting film and shall become a permanent record.
61. No grading for private improvements shall occur outside the limits of the subdivision unless a
grading or slope easement or agreement is obtained from the owners of the affected properties
and recorded. If the developer is unable to obtain the grading or slope easement, or agreement,
no grading permit will be issued. In that case the developer must either amend the tentative map
or modify the plans so grading will not occur outside the project site in a manner which
H:\WORD\RiddleU-andDeyelopment\CT\98-20\Conditionsdoc
REV. 9/23/99
Page: 2
substantially conforms to the approved tentative map as determined by the City Engineer and
Planning Director.
Dedications/Improvements
62. The developer shall install or agree to install and secure with appropriate security as provided by
law desiltation/detention/urban pollutant basin(s) of a type and a size and at location(s) as
approved by the City Engineer. The developer shall enter into a basin maintenance agreement
and submit a maintenance bond satisfactory to the City Engineer prior to the approval of grading,
building permit or final map whichever occurs first for this project. Each basin shall be serviced
by an all-weather access/maintenance road.
63. Additional drainage easements may be required. Drainage structures shall be provided or
installed prior to or concurrent with any grading or building permit as may be required by the
City Engineer.
64. The owner shall make an offer of dedication to the City for all public streets and easements
required by these conditions or shown on the tentative map. The offer shall be made by a
certificate on the final map for this project. All land so offered shall be granted to the City free
and clear of all liens and encumbrances and without cost to the City. Streets that are already
public are not required to be rededicated.
65. James Drive shall be dedicated by the owner along the project frontage based on a center line to
right-of-way width of 30 feet and in conformance with City of Carlsbad Standards.
66. Prior to approval of the final map, the applicant must submit recorded documents to verify
the off-site right-of-way of James Drive has been obtained. This development currently
proposes off-site public improvements outside the limits of the subdivision boundary, in
which right-of-way must be secured.
66. Prior to issuance of building permits, the developer shall underground all existing overhead
utilities within the subdivision boundary.
67. Direct access rights for all lots abutting Hillside Drive shall be waived on the final map.
69. The drainage system shall be designed to ensure that runoff resulting from 10-year frequency
storms of 6 hours and 24 hours duration under developed conditions, are equal to or less than the
runoff from a storm of the same frequency and duration under existing developed conditions.
Both 6 hour and 24 hour storm durations shall be analyzed to determine the detention basin
capacities necessary to accomplish the desired results.
70. The developer shall comply with the City's requirements of the National Pollutant Discharge
Elimination System (NPDES) permit. The developer shall provide best management practices as

GRADING
Quantities: Cut: 12,000 cy Fill: 29,000 cy Import: 17,000 cy
Permit required: Yes
Offsite approval required: Yes
Hillside grading requirements met: Yes
Prelin^arygeQtecrjnicaJ investigation performed foy^Hetheringtpn gn^neering, Ind = >; ;' ^ ;;v
The geotechnical report indicates that there are no major grading or soils related issues with the
proposed project.
DRAINAGE AND EROSION CONTROL
Drainage basin: AgutHedjonela Watershed : . i
Erosion potential: Low
Surface runoff from the development will be collected and conveyed by a proposed public storm
drain and inlet system in James Drive. The basin inlets are located near the cul-de-sac. This is a
sump condition, however, the development provides for a failsafe overflow. The project is also
required to provide drainage area fees under the City's Master Drainage Plan.
LAND TITLE
Conflicts with existing easements: No
Public easement dedication required: Yes
Site boundary coincides with Land Title: Yes
The right-of-way widths for Hillside Drive conform with City standards and no additional right-of-
way dedications are required. James Drive, a cul-de-sac street, will be dedicated as a public street
on the final map.
PAD ELEVATIONS FOR INFILL-LOT
This adjacent properties surrounding are developed and occupied with residential structures.
Visual impacts from these adjacent developments are measured by differences in existing and
proposed topography. The differences in elevations for each pad ranges from approximately
negative 2-feet to positive 14-feet. These elevation differences are inherent for each lot to be
H:\WORD\Riddle\LandDeveloproenl\CT\98-20\Conditions.doc
REV. 9/23/99

in-
accessible and serviceable to the proposed public street. The proposed pad elevations appear to
be consistent with adjacent properties.
IMPROVEMENTS
Offsite improvements: Yes
Standard Waivers required: No
A portion of the proposed improvements for James Drive is proposed outside the subdivision
boundary. Verification that off-site right-of-way is obtained is contingent on project approval.
