SUMMARY: The Monterey Peninsula Water Management District (MPWMD or District) is in the process of developing a Geographical Information System (GIS) covering the area within the District boundary. The GIS system will allow the integration of spatial or map-based information with other data. The purchase of current digital geo-referenced aerial photographic data (orthophotos) will enable MPWMD to produce accurate, professional-looking projects for analysis as well as presentation materials to facilitate internal and public education. The orthophotos will be used as a base layer for plotting and displaying the locations of various types of data within the MPWMD boundary. The orthophotos will allow MPWMD staff to prepare maps that show such information as well locations, Mitigation Program monitoring sites, and data on individual parcels for MPWMD’s water permit tracking and water conservation program. Work products and costs for the images are shown in Exhibit 8-A.

RECOMMENDATION: Authorize the Acting General Manager to purchase orthoimagery from the Association of Monterey Bay Area Governments (AMBAG) at a cost not to exceed $71,325. If approved, this item will be adopted along with the Consent Calendar. The Administrative Committee considered this item at its July 15, 2003 meeting and recommended approval by vote of 3 to 0.

IMPACTS ON STAFF AND RESOURCES: The Fiscal Year 2003-2004 budget includes funds to purchase orthoimagery. Funds in the amount of $70,000 are budgeted under Capital Assets, Computer Equipment, Aerial orthophotos for the Monterey Peninsula (Account No. 99-9160). Costs for the orthophotos will be $71,325, as shown in Exhibit 8-A. This amount is $1,325 greater than budgeted. This additional cost is due to an increase in quality (resolution) of photographs for urban areas of the MPMWD. Staff recommends the additional cost to obtain cleaner images for GIS presentations and mapping. The agreement with AMBAG for purchase of the orthophotos will be administered by Inder-Mohan Osahan, Chief Technology Officer, for MPWMD.

BACKGROUND: AMBAG has contracted with Sanborn Colorado, L.L.C. to perform the work necessary to produce the orthophotos. Sanborn will fly the aerial photographs and then process the images into a digitally accurate, seamless format. AMBAG has created a cost-sharing program in order to enable agencies to divide the costs of photographic “tiles” that are being requested by multiple agencies. Exhibit 8-A shows the tiles MPWMD will be receiving, along with the overlap with the other agencies.

Participants in the AMBAG orthoimagery project include MPWMD, Soquel Creek Water District, San Benito County Water District, Cal-Am, CSUMB, California Parks and Recreation Department in Monterey, U.S. Army Corps of Engineers, Pebble Beach Community Services District, the cities of Seaside, Del Rey Oaks, Monterey, Sand City, Soledad, Carmel, Santa Cruz, Capitola, and San Benito and Santa Cruz Counties.

MPWMD staff has worked with AMBAG representatives to determine the photographic resolution required for MPWMD projects. The final product will be a combination of photographic “tiles” covering all lands within the District boundary. Urban areas and parts of the Carmel Valley corridor will be taken with six-inch photographic resolution (each pixel of the photo represents a 6” square of ground) with two-foot contours. The photographic resolution for outlying rural areas within the District will be two-foot pixels.
