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. 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. 57. This project is within the proposed boundary of the Aviara Parkway - Poinsettia Lane Bridge and Thoroughfare Fee District. This project is required to pay a fair share contribution towards the construction of Poinsettia Lane in accordance with the proposed fee program. 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 is 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. 61.

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 substantially conforms to the approved tentative map as determined by the City Engineer and Planning Director. Dedications/Improvements 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.

Drainage outfall end treatments for any drainage outlets where a direct access road for maintenance purposes is not provided, shall be designed and incorporated into the grading/improvement plans for the project. These end treatments shall be designed so as to prevent vegetation growth from obstructing the pipe outfall. Designs could consist of a modified outlet headwall consisting of an extended concrete spillway section with longitudinal curbing and/or radially designed rip-rap, or other means deemed appropriate, as a method of preventing vegetation growth directly in front of the pipe outlet, to the satisfaction of the Community Services Director and the City Engineer. Final Mao Notes 78. Note(s) to the following effect(s) shall be placed on the final map as non-mapping data: 78.D. 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. Code Reminder The project is subject to all applicable provisions of local ordinances, including but not limited to the following: 79.
