Irrigation Maintenance. (a) The Supplier will be responsible for proper water management and that such systems are functioning properly. All systems should end their cycles as early in the morning as possible.
Irrigation Maintenance. 4.14.5.1. Furnish all material, labor, and equipment necessary for the inspection and maintenance of existing irrigation systems, as directed by NYCDOT.
Irrigation Maintenance. The Property Owner shall retain a licensed landscape contractor to maintain the irrigation system as it was approved by the City of Mission Viejo. Irrigation systems shall be turned on weekly, and the Property Owner shall require the contractor to walk the entire site to ensure that the irrigation system is functioning as designed and that all irrigation deficiencies are correctly within a 36- hour time period. The City will monitor irrigation performance to ensure runoff is reduced to the lowest level possible.
Irrigation Maintenance. Subject to the last sentence of this Section 6.08 the Tides shall be responsible for the resodding and regrading of the playing field, and Minor Maintenance and Repairs of the playing field’s irrigation system, which shall be completed as required by MLB or sooner upon agreement by the City and the Tides. The Tides shall solicit no fewer than three (3) businesses to submit bids for such work, and the bid selected shall be subject to review and approval by the City. The cost of the first (1st) such resodding and regrading of the playing field during the Term and the Major Maintenance and Repairs of the playing field’s irrigation system shall be part of the City’s financial obligation for Major Capital Improvements set forth in Section 7.03.
Irrigation Maintenance a. Reviews and repairs: Monitor all systems for water usage for proper operation after each mowing session.
Irrigation Maintenance. Ditch cleaning The open irrigation ditches are prone to vegetation growth, which slows the conveyance of water and clogs the buried mainlines. The ditches need to be mechanically cleaned at least yearly to remove xxxx and repair breaches, by using a backhoe. Clean out of the pipelines and the irrigation risers have to be fully opened to flush the pipes of sediment and vegetation. Irrigation maintenance cleaning is required annually, at a minimum, and as needed throughout the irrigation season. Diversion cleaning Permittee does not maintain a point of diversion on the North Annex Property. Fish Screen cleaning Permittee does not maintain a fish screen. Pasture Grazing Management Permittee has 30 to 50 distinct pastures where livestock graze. Livestock are rotated through the pastures as part of Permittee’s holistic pasture grazing management. The livestock are moved frequently based on a number of factors but primarily to avoid over- grazing and other impacts. The Enrolled Property tries to keep at least 4-6 inches of stubble remaining. This practice improves productivity of grass forage, by increasing root depths and improving the soil moisture retention, and also helps to reduce solar radiation of irrigation waters due to increased soil shading.
Irrigation Maintenance. Ditch cleaning Open irrigation ditches on Grenada Novy Ranches are prone to vegetation growth, which slows the conveyance of water and clogs the buried openings. The ditches need to be cleaned several times per year to remove vegetation, as well as to repair breaches. Cleaning ditches on both the Novy, Rice, Xxxxxx and Xxxx Pump ditches consists of mechanical raking with a backhoe. Smaller clogged openings require hand-shoveling or hand-digging. Diversion and Fish Screen Cleaning Novy, Rice, Xxxxxx Diversion: Grenada Novy Ranches has the primary responsibility of maintaining this diversion and has the full responsibility of cleaning and operating the fish-screen and fish bypass return. The diversion requires the use of vertical flash boards and tarps which are inserted or removed based upon water flow to maintain necessary water diversion. Flash board insertion requires the use of heavy equipment to position the boards prior to placement against the flashboard dam. High water events require careful monitoring and full removal of the flash boards at the diversion. The fish screen needs daily maintenance, up to three times a day, to remove decaying aquatic vegetation other debris released from the river and ditches. An individual from the California Department of Fish and Wildlife comes once a week to inspect, clean and flush the diversion as well. Novy Pump Diversion: Grenada Novy Ranches maintains the cone fish screen and pump solely. Maintaining the fish screen involves removing the sand/silt from around the cone screen while operating instream and these daily inspections also insure that the cone screen is operating correctly. Fish screen maintenance can involve a high water pressure hose as well as seasonal large equipment work. Maintaining the pump requires lubrication, maintenance, and sometimes a full shut-down, start up several times each week. The Novy Pump has a current, updated Streambed Alteration Agreement (Appendix F) for the operation and maintenance of the compliant self-cleaning fish-screen and diversion intake.
Irrigation Maintenance. Ditch cleaning The open irrigation ditches are prone to vegetation encroachment, which slows the conveyance of water and clogs the buried mainlines. The ditches need to be mechanically cleaned at least yearly to remove vegetation and repair breaches, by using a backhoe. The head works of all the pipelines have grates that are cleaned daily to keep them functioning properly. Clean out of the pipelines and the irrigation risers have to be fully opened to flush the pipes of sediment and vegetation. Irrigation maintenance cleaning is required annually, at a minimum, and as needed throughout the irrigation season. Diversion cleaning The rock xxxxxx at the diversion structure and the head gate can become clogged with debris, blackberries, or become part of beaver dams. They need to be periodically cleared mechanically to ensure proper operation. This entails the use of heavy equipment every few years, as needed, to clear large woody debris in the spring of the year prior to diversion operation. A CDFW Sec. 1600 LSAA permit exists for this purpose since 2000. Fish Screen cleaning Since the existing fish screen is a passive tube screen placed down ditch, it needs to be cleaned daily to ensure the full prior right volume can be conveyed to the pipeline. It often becomes clogged with vegetation and at times needs to be cleaned more often than once per day. Screen cleaning consists of hand raking vegetation off the screen which will be covered under the Site Plan Agreement until replaced with a on channel cone screen. After the installation of the proposed fish screen, as described in Section E.2.b, the Permittee will need to periodically lift the screen with the assistance of heavy equipment to clean out any sedimentation that has settled in the screen structure. The proposed screen is a self-cleaning screen, so daily hand cleaning of the screen will not be necessary, however brushes will need to be checked yearly and replaced when needed, approximately every 5 years.
