make note of management strategies that will help to improve on the issue at hand. Discuss patterns that you observe and items that you need the City of Redwood City to address such as installation of a dock under the bridge for mooring, or installation of a ramp on the Eastern Lagoon side for harvester access. These are a few things that might be included in that report. Lastly discuss ways to possible save the City money in their Lagoon Management program; with Government budgets hurting, creative partner shipping of Municipalities with vendors is a possible future we might explore. This report will be due on October 31, 2009 and will be compiled and written by Rich Carnation and Sara Burnsed, with input from Waterworks Industries staff. It is important to say that while Waterworks Industries has the cost of these services included in their Schedule of Fees, Waterworks Industries has not charged Redwood City for the attendance of the preseason or post season meetings or report preparation. ill MECHANICAL HARVESTING Mechanical harvesting of Algae and Widgeon Grass shall be performed as needed resulting from Water Quality Monitoring (surveys) described above. The harvesting shall be performed when the Widgeon Grass is within one foot of the lagoon surface or sooner if it were determined that to wait would jeopardize the beneficial uses of the lagoon. Mechanical harvesting is a necessary component of the lagoons management approach from a nutrient management standpoint. The fast growing Widgeon Grass requires a lot of food to support the growth. It is through the nutrient uptake of the Widgeon Grass and its subsequent harvesting and removal from the Lagoon system that aids in the reduction in algaecide use, as the food that the algae needs to grow has already been utilized by the Widgeon Grass. In addition to mechanical harvesting, hand harvesting by Waterworks Industries Staff Technicians of areas around docks and beaches where the mechanical harvester cannot reach is important. If the vegetation that has broken loose and drifted into the tight areas is allowed to decompose and re-release the nutrients back into the water column, the possibility for algae growth has increased significantly. Waterworks Industries staffing and equipment includes one senior technician, one staff technician, eight foot head mechanical harvester, conveyer trailer, 25,000 GVW vehicle to tow trailer, fuel. Waterworks Industries currently own six harvesters, Waterworks Industries commitment to Redwood City is to have One Harvester on location at Redwood Shores Lagoon from April 1 through September 30 as a guarantee of service. Waterworks has prioritized Redwood City as a preferred Vendor. Waterworks Industries wants to continue to provide top-notch service. Should the growth of the Widgeon Grass or algae accelerate beyond the ability for one harvester to proactively handle the growth. Waterworks Industries will bring in a second Harvester within 24 hours of identifying the accelerated growth. As per our staff, we are prepared to handle the acceleration of the vegetation growth in an expeditious manner. Our other harvesters are used for other clients work. There may be times when more than two harvesters are in use at Redwood Shores. Waterworks Industries in its commitment to the City of Redwood City has removed the diesel powered motors from the harvesters and has spent a considerable amount of capitol re-powering .lfl 13 of 20
