Gilbert, Director of Public Works C DATE: July 27, 1998 (Council Meeting 8- 19 -97) SUBJECT: Consider Selection of a Consultant to Prepare a Finance / Implementation Plan for the Gabbert Canyon / Walnut Canyon Channels Deficiency Study BACKGROUMD 1. In 1996 the Ventura County Flood Control District (VCFCD) retained the services of Robert Bein, William Frost & Associates to prepare a study to evaluate the deficient drainage facilities serving the Walnut Canyon watershed and the Gabbert Canyon watershed, and to recommend alternative design concepts aimed at correcting those deficiencies. 2. In June of 1997, the City Council reviewed that draft study and concurred with the recommendations of the consultant, VCFCD and City staff with regard to the preferred conceptual design alternate for the needed future improvements. Subsequently, the VCFCD adopted that design option as the approved Design Alternate for the future drainage improvements required for these watersheds. 3. Attached as Exhibit 1 is a diagram illustrating the project(s) proposed by the approved Design Alternate. These proposed drainage improvements consist of a combination of detention (construction of a number of new detention basins), diversion (construction of a new north -south drain line in the vicinity of Shasta Avenue) and channel capacity improvements. The total cost of these proposed drainage improvements is estimated to be in excess of $13 million. gab2 n Gabbert Canyon / Walnut Canyon Study August 19, 1998 Page 2 Considerable interest has been expressed by owners, or agents representing owners, of a number of the properties within these watersheds, to proceed with plans for the development of those properties. The properties expressing such interest include: the developers of Specific Plan #1; Westpoint (T4620); Suncal Properties; Tract 5130 (Revision to SP -10); and, the proposed Industrial Site on the north side of Los Angeles Avenue west of the SCE sub - station (Bugle Boy). of course, the conditions of approval for each of those future developments will require the construction or funding of a "fair- share" portion of the required drainage improvements. It is necessary, therefore, for the City to determine what the "fair- share" distribution of those costs will be. In order to accomplish this task, it will be necessary for the City to develop a method and means to equitably allocate the cost of the required drainage improvements to the properties to be benefitted by those improvements. Accordingly, City staff asked Robert Bein, William Frost & Associates to submit a proposal (Exhibit 2) for the preparation of a Project Implementation Financial Plan for the required drainage improvements. The scope and purpose of that report is generally described as follows: 1. evaluate financing options: public, private, assessment district, applicability, economic feasibility, practical feasibility, etc.; 2. review and update prior project construction cost estimates; 3. define properties to be benefitted, develop rules /methodology for the equitable spread of costs to benefitted properties, prepare preliminary benefit spread formula(s), prepare preliminary assessment spreads (assessment amounts) to benefitted properties; and, 4. define an implementation schedule / priority list of required improvements. The fee for this study is $18,200. The funding source will be advance deposits by one or more of the above mentioned developers. It should be noted that this study will not necessarily identify the requirements for each property to be developed. It will only provide amount for a "fair - share" distribution of drainage improvement costs. Using this information, staff (with input from the VCFCD) will develop the actual conditions and requirements for each property on a case by case basis, taking note of such factors as current risk of inundation, current and proposed storm water run -off and order of development. gab2 1,3 Ota Gabbert Canyon / Walnut Canyon Study August 19, 1998 Page 3 10ocksiXt _ ► ' Staff recommends that the City Council take the following actions: 1. Approve the selection of Robert Bein, William Frost & Associates (RBF) to prepare a Finance / Implementation Plan for the Walnut Canyon / Gabbert Canyon drainage improvements, for a fee not to exceed $18,200. 2. Direct staff to work with the developers of properties within these watersheds to obtain advance payment of the fees required for the subject study and authorize the City Manager to sign an Agreement with one or more of those developers to provide for a credit in favor of said developer(s), against future payment of development fees or improvement costs. 3. Authorize the City Manager to execute a contract with RBF for said services, upon receipt of said advance payment. gab2 a00 IN -984 CFS 0100 OUT 514 CFS OBYPASS -902 CFS STOW VOL -145 AC -FT SED.
