Mullet, Mayor Department of Community Development Steve Lancaster, Director MEMORANDUM FROM: RE: DATE: Mayor Mullet City Council \...-./ Steve Lancaster, DCD Director ~ GIS Update Contract March 16,2005 TO: BACKGROUND The City originally purchased digital orthophotos to use with our GIS system in 2000. These were flown in the summer of 1999 by Triathlon and had 6" pixels. We also contracted with Triathlon to create contours, building footprints, edge of pavement, sidewalk and driveway layers. The total cost for this was approximately $80,000. In 2004 we looked into reflying the City for new orthophotos and updating the photo-based layers, but estimates were much higher than our budgeted amount. Instead we purchased orthophotos from a 2002 flight by the Washington Department of Natural Resources that were made available for the cost of the hard drive to store them (approximately $600). While these were more recent, they were also less detailed, with aI' pixel size. Therefore they could not be used as a basis to update the GIS layers. We received an estimate from Triathlon of the cost to fly new photos and update our layers (including adding the annexation areas) of approximately $34,000 and budgeted for that in 2005. DISCUSSION Early this year Triathlon disbanded its local mapping division. A former Triathlon employee who has started a consulting business approached the City about proceeding with the update using the same pilot and mapping subcontractor proposed by Triathlon and within the same budget amount. Together we developed the attached contract and scope of work. We had originally hoped for a flight date of late February or early March in order to take advantage of leaf-off conditions. Leaves obscure the ground and create dark shadows, especially in residential areas, and make the GIS layers derived from the photos less accurate. Due to the Q \GISStuft\Ortho\ContractCC.DOC Page 1 6300 Southcenter Boulevard, Suite #100 · Tukwila, Washington 98188 · Phone: 206-431-3670 · Fax: 206-431-3665 amount of time necessary to negotiate the contract and the warm spring weather we are nearing the end of the window for good photo conditions. The orthophotos have become widely used throughout the City and are a valuable tool for communicating with the public. We invested a considerable amount of money to create the photo-based layers in 2000, but they will gradually become unreliable unless we update them on a regular basis. The attached photos show how the existing GIS layers are inaccurate because the do not include new development. Our current GIS layers also do not cover Tukwila's proposed annexation areas. RECOMMENDATION Staff recommends that the Council authorize the Mayor to proceed with the contract with GPS Surveying for the new digital orthophotos and the updated contours, building footprints, edge of pavement, sidewalk and driveway layers.

Weare excited about the opportunity to work with you and we will apply our extensive skills and experience to give TUKWILA the best mapping products and services available. Our team consists of: GPS Surveying, Lynnwood, W A Brown Mapping Consultants, Bellevue, W A Alexander Ginkas and Associates, Vancouver, BC David Brown will be the Project Manager and point of contact during the project. SCOPE OF WORK Aerial Photography GPS Surveying (OPS) will acquire the aerial photography. The airplane is equipped with a Zeiss LMK 2000 aerial mapping camera with a six-inch focal length lens. The camera is gyroscopically stabilized and has forward motion compensation. We will be using Kodak 2444 Aerocolor film. The nominal photoscale will be 1 "=600' or 1 :7,200. The photography will be flown with sun angles greater than 30 degrees and will not be taken if the ground is obscured by atmospheric conditions such as haze, dust or smoke, clouds or cloud shadows; snow and floodwaters. The film will conform to industry standards for pitch, roll, and yaw. Max tilt 3 degrees Tilt between exposures 4 degrees Max crab 3 degrees Crab between exposures 3 degrees The aerial photography will be completed by March 31, 2005 weather permitting. A flight report and sample scans will be made available to TUKWILA two weeks after the flight. 1 Control GPS Surveying will also provide the Airborne GPS (ABGPS) required to geo-reference the photography. This is where a GPS receiver is mounted in the aircraft to record coordinates during the flight. With this information the coordinate of the camera can be interpolated for each exposure. It requires that two base station GPS receivers are also recording data on the ground during the mission. The advantage of ABGPS is that only the perimeter of the project area needs to have targeted ground control points reducing the cost of the control. We will also want to review the existing control that the City of Tukwila has established. Premarking selected control points prior to the flight can greatly enhance the accuracy of the project. Digital Orthophotography Color digital orthophotography will be produced with a 0.5 foot pixel. The orthophotos would be delivered as TIFF image files on DVD disk or CDROM. Each file would cover an area 3000'x 3000' and would be 108 MB in size. Approximately 55 images would be required to cover the greater Tukwila area. These would also be compressed into a single MrSID fonnat image using a 20: 1 compression ratio. Digital Elevation Model A digital elevation model (DEM) will be updated by mapping breaklines along significant topographic features and collecting mass points at regular intervals throughout the stereomodel. Using this DEM, we will produce 2-foot contour map of the entire proj ect area. We will also produce polygons of areas that are obscured by vegetation and shadows. Contours in areas that are obscured by vegetation or shadows will be dashed indicating that they are indefinite. Contours will be delivered as Arclnfo coverages version 8.3 fonnat. No hardcopy plots will be delivered. Planimetric l\tlapping The planimetric features will be updated from the new photography. The features that will be mapped are: Commercial and residential building footprints (excluding lawn sheds) Edge of pavement Driveways Commercial parking lots Public sidewalks Hydrology including streams and water bodies In addition, the two annexation areas in Figure 1 will be newly mapped. Contours and planimetic features will be seamlessly tied to the existing mapping. 2 All new linework will be topologically structured, clean data that is noded \vith no overshoots or undershoots. A pilot set of contour and planimetric data will be delivered to TUKWILA to insure that the mapping meets the specification. TUKWILA requires three weeks to review the completed dataset for completeness and quality. Any revisions that are required 'Ni.ll be completed in two weeks. The planimetric data will be delivered by June 15t , 2005 assuming a March flight. Accuracy All mapping will be produced in compliance with the National Map Accuracy Standards (NMAS) for 1 OO-scale horizontal mapping and 2.0 foot vertical accuracy. The horizontal datum will be NAD 83/91 Washington State Plane Coordinates, North Zone and the vertical datum will be NA VD 1988. Deliverables The standard deliverables for this project would be: Planimetric and contour files in Arclnfo version 8.3 format. ASCII DTM/DEM files Digital orthophotos in TIFF format and MrSID Costs The lump-sum cost to complete the entire project is $34,350.00 USD. All data and orthophotography will become the property of TUKWILA and will be free of licenses and restrictions. TUKWILA will be invoiced for three equal payments upon: Acceptance of the aerial photography Delivery of draft planimetrics Acceptance of fmal planimetrics.

Brown Certified Photogrammetrist dbrown@isomedia.com (425) 214-2257 3 Figure 1 Mapping Limits 4 Community Affairs and Parks Committee March 15, 2005 " ; A second decision is whether the city should require a business license for multi-family and accessory dwelling units. Dennis thought there was not a council consensus on this issue, though he and J oe suppo~ed it and Joan would like more infonnation on it. Kathy reported being allowed in one apartment unit with obvious health and safety violations. Mandatory inspections of apartment units is also an option that could come with licensing, though the legality of that is unclear. Refer issue to COW. 4. Proposed code amendments Thp committee considered ten draft code amendments. Staff had listed options~ and included recommendations on each amendment. Because cities are required by State law to accept manufactured homes beginning July 1 st this year, City standards need to be established.. Nora said manufactured homes come in a range of quality, from very basic trailer types to homes hard to distinguish from stick-built homes. Staff had written changes to the single family dwelling code that manufactured homes would need to follow, and the recommendations would lead to a higher quality manufactured home. The committee largely followed the staff recommendations. Committee members had some questions about appropriate requirements for condo conversions and which requirements might be appropriate, and on whether a dog kelll1el was appropriate in the urban center. Refer issues to Planning Commission. 5. Sinele Family Neighborhood Housing Options Moira said most developments for single family homes put in a standard home with a garage in front. The Comprehensive Plan encourages a range of housing types. Some options include cottage housing, where small homes are clustered around a common green, with parking in the back or on the sides, and porches facing one another. There is an opportunity for this type of housing in a demonstration project in the city, though an ordinance would need to be passed to allow that. The committee supported cottage housing on a demonstration project basis. Return to Committee with specific recommendations for allo,ving demonstration proiects. +- 6. Aerial survey DCD has budgeted an aerial survey of the entire city and is eager to proceed with that survey before the trees leaf out any more than they already have. The photos will be used to update the city GIS (geographic infonnation system). Funding comes from both the DCD and Public Works budgets. Recommend contract for aerial photography to Re2ular Meetin2.
