King County shall have the right to ingress and egress over those portions not contained in Exhibit "A" to access such easement area for inspec- tion of and to reasonably monitor the system for performance, operational flows, or defects in accordance with and [as presented in King County Code Section 9.04.120] . 2. If King County determines that maintenance or repair work is required to be done to the system, the Manager of the Surface Water Management Division of the Department of Public Works shall give notice of the specific maintenance and/or repair required pursuant to K.C.C. 9.04.030. The Manager shall also set a reasonable time in which such work is to be completed by the Grantor(s) , its heirs, successors or assigns. If the above required D8:Ml16 - 1 52 maintenance and/or repair is not completed within the time set by the Manager, the County may perform the required maintenance and/or repair. Written notice will be sent to the Grantor(s) stating the County's intention to perform such maintenance. Maintenance work will not commence until at least seven (7) days after such notice is mailed. If, within the sole discretion of the Surface Water Management Division Manager, there exists an imminent or present danger, said seven (7) day notice period will be waived and maintenance and/or repair work will begin immediately. 3. If at any time King County reasonably determines that any existing retention/detention system creates any of the conditions listed in K.C.C. 9.04.030 and herein incorporated by reference, the Surface Water Management Division Manager may take measures specified therein. 4. The Grantor(s) shall assume all responsibility for the cost of any maintenance and for repairs to the system. Such responsibility shall include reimbursement to the County within thirty (30) days of the receipt of the invoice for any such work performed. Overdue payments will require payment of interest at the current legal rate as liquidated damages. If legal action ensues, the prevailing party is entitled to costs or fees. 5. The Grantor(s) is (are) hereby required to obtain written approval from the Surface Water Management Division Manager of the King County Department of Public Works prior to filling, piping, cutting, or removing veg- etation (except in routine landscape maintenance) in open vegetated drainage facilities (such as swales, channels, ditches, ponds, pond, etc.) , or perform- ing any alterations or modifications to the drainage facilities contained within said drainage easement. Any notice or consent required to be given or D8:MI16 - 2 - 54 otherwise provided for by the provisions of this Agreement shall be effective upon personal delivery, or three (3) days after mailing by Certified Mail , return receipt requested. 6. This Agreement constitutes the entire agreement between the parties, and supersedes all prior discussions, negotiations, and all agreements whatso- ever whether oral or written.
