condition as determined by the City Engineer, the City, its agents, employees, or
its contractors, may enter upon the Property and take the steps deemed

the Parties. In the event the City pursuant to this Agreement, performs work of
any nature, or expends any funds for attorney's fees, administrative costs,
contractors, employees, consultants, materials, or other costs in the performance
of said work, the Owner shall reimburse the City. Such reimbursement shall be
due within thirty (30) days of receipt of a notification for all costs incurred by the
City, including any administrative costs and attorney's fees. If said funds are not
paid by the Parties within (30) days, City reserves the right to take legal action for
cost recovery and to file with the County Recorder of San Diego County an
assessment lien on the Property. It is expressly understood and agreed that the
City is under no obligation to perform Maintenance of said Stormwater Facilities,
and in no event shall this Agreement be construed to impose any such obligation
on the City.
15. The terms of this Agreement may be amended in writing following the Parties
request and upon written approval by the City Engineer.
16. This Agreement shall be governed by the laws of the State of California. In the

INSPECTION / MAINTENANCE CONSIDERATIONS:
BIORETENTION REQUIRES FREQUENT LANDSCAPING MAINTENANCE, INCLUDING MEASURES TO ENSURE THAT THE AREA IS
FUNCTIONING PROPERLY, AS WELL AS MAINTENANCE OF THE LANDSCAPING ON THE PRACTICE. IN MANY CASES,
BIORETENTION AREAS INITIALLY REQUIRE INTENSE MAINTENANCE, BUT LESS MAINTENANCE IS NEEDED OVER TIME. IN
MANY CASES, MAINTENANCE TASKS CAN BE COMPLETED BY A LANDSCAPING CONTRACTOR, WHO MAY ALREADY BE
HIRED AT THE SITE.
