24.10.010 GIS requirements for commercial/industrial lots and multifamily developments.
Prior to receiving an occupancy permit developers/owners of commercial properties, industrial properties and multifamily properties shall submit to the City drawing files in AutoCAD format (latest release), on three-and-one-half-inch discs, accompanied by the original mylars (record drawings) which indicate the building footprint(s), utility services and all impervious surfaces. All changes from the original approved plans shall be clearly marked on the record drawing to reflect as-built conditions. If the property has existing buildings, impervious areas, and utilities, which are not on the City’s GIS, the developer/owner shall also include the existing facilities. The AutoCAD drawing files shall reflect as-built conditions and shall be supplied in the format listed below:
The AutoCAD files shall be structured so that the following drawing entities are developed using a single polyline to create a polygon. The entities shall be placed on a unique layer as listed.

24.10.040 Noncompliance.
Owners who do not comply with all or any part of the requirement, described herein shall pay the cost for the City (or the City’s consultant) to perform the work required to bring the owner’s drawings into conformance with the requirements herein. Costs for said work shall be billed on time and materials, plus an administrative fee of two and one-half percent. (Ord. 97-559 § 4; Ord. 07-835 § 1).
24.10.050 Fee for installation.
The developers/owners of commercial, industrial, multifamily facilities, right-of-way improvements, and subdivisions shall pay the City to install the AutoCAD files onto the City’s GIS. Upon receiving the AutoCAD files the City will estimate the installation cost. The developer shall deposit with the City 150 percent of the estimated fee, together with two and one-half percent thereof for the administrative costs of the City thereon, prior to receiving an occupancy permit. Upon completion of the GIS installation the City will forward an invoice summarizing the cost to the developer/owner. The City will refund any remaining funds. If the estimate is exceeded the developer will pay the City the additional funds within 30 days of receiving the invoice from the City. Any such refund or additional billing shall reflect appropriate reduction or increase in the City’s two and one-half percent administrative fee. (Ord. 97-559 § 5; Ord. 07-835 § 1).
