INDEMNIFICATION. This Agreement imposes no liability of any kind whatsoever on the City. The Declarant hereby agrees to indemnify and hold harmless the City and its agents and employees against any and all claims, demands,losses,damages,and expenses(including reasonable attorneys'fees)arising out of or resulting from the Declarant or the Declarant's agents or employee's negligent or intentional acts, or any violation of any safety law, regulation or code in the performance of this Agreement, without regard to any inspection or review made or not made by the City,its agents or employees or failure by the City, its agents or employees to take any other prudent precautions. In the event the City, upon the failure of the Declarant to comply with any conditions of this Agreement, performs said conditions pursuant to its authority in this Agreement,the Declarant shall indemnify and hold harmless the City,its employees,agents and representatives for its own negligent acts in the performance of the Declarant's required work under this Agreement, but this indemnification shall not extend to intentional or grossly negligent acts. 6.

All features requiring maintenance identified on the scaled site plan for the Property attached hereto and incorporated herein as Attachment A will be maintained in perpetuity in accordance with as follows: 1. WATERBODY CROSSINGS& STRUCTURES a. Crossings and structures in contact with the bed or bank of a waterbody will be inspected at least once every 5 years and maintained in good repair in perpetuity to ensure continuing adequate hydraulic and navigational capacity is retained in accordance with approved plans,to ensure no net increase in the flood stage beyond that achieved by the approved plans,to prevent adverse effects on water quality,changes to the existing flowline/gradient and increased scour, erosion or sedimentation, and to minimize the potential for obstruction of the waterbody. 2. STORMWATER FACILITIES a. Underground storage facilities. Underground storage facilities will be inspected at least annually to ensure continuing performance per design. Capacity will be considered inadequate if sediment has decreased the storage volume by 50 percent of the original design volume. Accumulated debris and sediment will be removed, and inlet and outlet structures will be kept clear of any flow impediments. b. Grit chambers,sump catch basins and sump manholes. Grit chambers, sump catch basins and sump manholes will be inspected once each year. All sediment and debris will be removed as needed such that the stormwater facilities operate as designed and permitted. c. Proprietary stormwater facilities. Proprietary stormwater facilities will be inspected at least annually and maintained as specified or recommended by the manufacturer and/or installer as described in Attachment B. d. Scope of Inspection. The inspection shall cover, without limitation,the entire stormwater runoff management facilities,including access roads and buffers. Deficiencies shall be noted in the inspection report. A stormwater runoff management facility will be considered inadequate if it is not compliant with all requirements of the Plan approved by the City and MCWD and City stormwater maintenance standards. e. Reporting. The Declarant will submit to the MCWD and to the City once every 5 years a brief written report that describes stormwater facility maintenance activities performed under this declaration, including dates,locations of inspections and the maintenance activities performed. The Declarant shall be responsible for the payment of any associated costs. f. City Access and Maintenance Rights. The Declarant hereby grants permission to the City, its authorized agents and employees,to enter upon the Property and to inspect the stormwater runoff management facilities whenever the City deems necessary. The City shall provide the Declarant,its successors and assigns, copies of the inspection findings and a directive to commence with the repairs if necessary. g. Failure to Maintain. In the event the Declarant, its successors and assigns, fails to maintain the Stormwater Facilities in good working condition acceptable to the City and such failure continues for 60 days after the City gives the Declarant written notice of such failure, the City may enter upon the Property and take whatever steps necessary, including excavation and the storage of materials and equipment, to correct deficiencies identified in the Inspection Report. The City's notice shall specifically state which maintenance tasks are to be performed. The City may charge the costs, including assessing the City's costs to the Declarant's property taxes of such repairs,to the Declarant, its successors and assigns. This provision shall not be construed to allow the City to erect any structure of permanent nature on the land of the Declarant outside of the Easement Area for the Stormwater Facilities. It is expressly understood and agreed that the City is under no obligation to routinely maintain or repair said Stormwater Facilities, and in no event shall this Agreement be construed to impose any such obligation on the City. In addition,Declarant agrees that it is, and will be, solely responsible to address complaints and legal claims brought by any third party with regard to the maintenance and operation and the consequences there from the Stormwater Facilities. The Declarant expressly agrees to defend and hold the City harmless from any such third-party claim. 3. GRANT OF EASEMENT a. Declarant hereby grants to the City, its successors and assigns, a permanent non- exclusive easement for the purpose of accessing and maintaining the Stormwater Facilities pursuant to the terms of this Agreement over, on, across, under and through the Easement Area. b. The easement shall include the rights,but not the obligation,of the City, its contractors, agents,servants, and assigns,to enter upon the Easement to construct,reconstruct, inspect,repair, and maintain said private Stormwater Facilities together with the right to grade, level,fill, drain,pave,and excavate the Easement Area,and the further right to remove trees, bushes,undergrowth,and other obstructions interfering with the location, construction,and maintenance of said private Stormwater Facilities systems. 4. REIMBURSEMENT OF COSTS The Declarant agrees to reimburse the City for all costs incurred by the City in the enforcement of this Agreement, or any portion thereof,including court costs and reasonable attorneys'fees. 5. INDEMNIFICATION. This Agreement imposes no liability of any kind whatsoever on the City. The Declarant hereby agrees to indemnify and hold harmless the City and its agents and employees against any and all claims, demands,losses,damages, and expenses (including reasonable attorneys'fees) arising out of or resulting from the Declarant or the Declarant's agents or employee's negligent or intentional acts, or any violation of any safety law, regulation or code in the performance of this Agreement, without regard to any inspection or review made or not made by the City,its agents or employees or failure by the City, its agents or employees to take any other prudent precautions. In the event the City, upon the failure of the Declarant to comply with any conditions of this Agreement, performs said conditions pursuant to its authority in this Agreement,the Declarant shall indemnify and hold harmless the City,its employees, agents and representatives for its own negligent acts in the performance of the Declarant's required work under this Agreement, but this indemnification shall not extend to intentional or grossly negligent acts. 6. RECORDING, BINDING EFFECT. This Agreement is a personal obligation of Declarant for so long as Declarant owns fee title to the Subject Property and shall be binding upon the executors, administrators, successors, heirs and assigns of Declarant with respect to Declarant's obligations and liabilities under this Agreement that relate to the period of its ownership. This Agreement shall be recorded against the title to the Subject Property and shall run with the land and be binding upon each owner of fee title to the Subject Property with respect to the period of its ownership. Upon the conveyance of fee title to the Subject Property, the transferor will have no further obligations or liabilities under this Agreement that relate to any time after the conveyance,and the new owner will, by accepting title to the Subject Property, become bound by this Agreement with respect to all obligations and liabilities of the "Declarant" that relate to any time after the conveyance, for as long as the new owner owns fee title to the Subject Property. Both the Declarant and a subsequent property owner are liable to the MCWD and the City for performance under this Declaration, and the MCWD and/or the City may seek any remedy in law or equity against the Declarant as long as the declarant owns the Property,and thereafter against a subsequent property owner to enforce this Declaration.
