Future Efforts When Caltrans approval of the conceptual design is obtained, the design consultant and/or City staff will proceed with project implementation, which will include the following: 1 . Right-of-Way Legal Descriptions: The design consultant will proceed with the preparation of legal descriptions for the right-of-way parcels to be acquired. 2 . Preparation of Final Draft Design Plans and Specifications: The design consultant will proceed with the preparation of the final draft plans and specifications for the project . 3 . Utility Coordination / Relocation : The design consultant and City staff will work with all affected utilities to accomplish any needed utility relocations . 4 . Right-of-Way Acquisition: Staff will retain the services of a consultant to assist City staff in the acquisition of the required street rights-of-way. All of the acquired rights- of-way will eventually be conveyed to Caltrans . 5 . Caltrans Permit: Staff will seek and obtain a Caltrans Encroachment Permit for the project . 6 . Construction: When all of the above tasks have been completed, the City will be in a position to advertise for the receipt of bids for the construction of the project .

Attachments : Exhibit 1 : Project Description LA_Spg_Mpk_NegDec ^.j�;{ Exhibit 1 Project Description October 22, 2001 Page 1 A. General Project Scope 1 . Purpose: The purpose of the project is to widen Los Angeles Avenue between Spring Road and Moorpark Avenue to accommodate six (6) lanes of traffic . 2 . Project Limits : The limits of the project extend from Moorpark Avenue easterly to a point approximately five hundred feet (500' ) east of Spring Road. The total length of the project is approximately 2300 feet . 3 . Existing Right-of-Way and Travel Lanes : The existing right- of-way width along this segment of street varies from eighty feet (801 ) to one hundred nine feet (109' ) . The street is striped for four (4) twelve feet (12 ' ) wide travel lanes, plus a fourteen feet (14 ' ) wide painted median. 4 . Design Standard: The design standard for Los Angeles Avenue calls for a curb-to-curb width of one hundred two feet (1021 ) within a street right-of-way of one hundred eighteen feet (1181 ) . Accordingly, the "half-street" dimensions require fifty-one feet (511 ) from the centerline to the curb face, within a "half street" right-of-way of fifty- nine feet (59 ' ) . 5 . Project Objectives : The object of the project is to construct full-width street improvements within the project area, generally described as follows : - one 14' painted median; - six-12' travel lanes; - two-8' emergency lanes (unpainted bicycle lanes) ; - two-8' sidewalk / parkways; and - free right turn lanes where necessary. B. Shifted Centerline Due to certain existing improvements along the north side of the street west of Spring Road (see below for details) , the Conceptual Plan calls for an eleven feet (111 ) shift of the centerline to the south, between Spring Road and Millard Street . East of Spring Road and west of Millard Street there will be a tapered transition from the "shifted" centerline back to the existing centerline at the east and west project limits . The "shifted" centerline is necessary in order to provide for the required fifty-one feet (51 ' ) dimension between the centerline and the north curbface. Exhibit 1 Project Description October 22, 2001 Page 2 C. Project Constraints and Design Solutions 1 . North Side - West of Spring Road a) Constraints : • Half-street right-of-way width: fifty feet (50' ) ; • Curb location: forty feet (40' ) from the center line; • Existing Improvements : - Existing residential rear yards; - a ten feet (101 ) high block wall ; - parkway landscaping; and - power poles . b) Design Solution: Due to the high cost of right-of-way acquisition, and the removal and reconstruction of the existing improvements on the north side of the street just west of Spring Road, the Conceptual Plan calls for all required street widening in this area to occur on the south side of the street . To achieve the required street width, the centerline will be shifted to the south. 2 . South Side - East of Moorpark Avenue a) Constraints : The south side of the street just east of Moorpark Avenue has been improved to its full width (fifty-one feet [511 ] from centerline to curb, within fifty-nine feet [591 ] wide half-street right-of-way) . There are substantial existing improvements in this area, generally summarized as follows : • existing properties already developed for multi- family land use; • decorative block walls and monument signs; and • meandering sidewalks and parkway landscaping . b) Design Solution: Due to the relative higher cost of right-of-way acquisition and reconstruction along the south side of the street in this area, the Conceptual Plan calls for the centerline to remain at its present location. Certain widening, relocation and improvement will be required along the north side of the street in this area. D. Other Design Elements 1 . East-End Transition : As mentioned above, the centerline will taper from the "shifted" centerline [eleven feet (111 ) ] at the west side of Spring Road, back to the current centerline to the east . The length of this transition will be approximately five hundred feet (5001 ) . It will be necessary to acquire additional street right-of-way and reconstruct certain street and off-site improvements in this area [Chevron Station and Bank of America] . Exhibit 1 Project Description October 22, 2001 Page 3 2 . West-End Transition: At Millard Street the centerline will also transition from the "shifted" centerline back to the existing centerline to the west. Here too the length of the tapered transition will be approximately five hundred feet (500' ) . a) Additional street right-of-way will have to be acquired on the north side of the street in the transition area, ranging from zero at the Millard Street to nine feet (91 ) wide at the west end of the transition. b) The transition to the north will also require the reconstruction of the curb, gutter and sidewalk in this area. 3. North Side West of the Tapered Transition: In order to achieve a fifty-nine feet (591 ) wide half-street west of the westerly transition, it will be necessary to acquire an additional nine feet (9' ) of street right-of-way and to reconstruct street improvements in this area. 4 . Power Poles & Underground Utilities: The project will require the relocation of the power poles and certain modifications to some of the recently installed underground utility vaults . 5. South Side R-O-W at 148 Los Angeles Avenue: There is an existing residential structure located between the Le Club Apartments and the Regal Condominiums . The street right-of- way required at that location will probably require acquisition of the entire property. 6. East-to-North Left-Turn Lane at Spring Road: The existing double left-turn lane will be changed to a single left-turn lane. 7 . West-to-South Left-Turn Lane at Moorpark Avenue: The existing left-turn lane will be lengthened. The plans do not call for a double left-turn lane at this location. E. Right Turn Lanes 1 . Westbound at Moorpark Avenue: The Conceptual Plan calls for an additional right-turn lane for Moorpark Avenue, to be constructed west of Flory Avenue. It is anticipated that the additional street right-of-way and street improvements required for these improvements will be six feet (61 ) wide. The design Engineer is seeking Caltrans approval of this design feature. e Exhibit 1 Project Description October 22, 2001 Page 4 2 . Eastbound at Spring Road: The Conceptual Plan also calls for additional street widening on the south side of the street just west of Spring Road, to provide for a free right turn lane on to Spring Road. Once the additional street width for this feature is determined by Caltrans, the impacts of this design element on the off-site and on- site improvements in the area will be assessed and a report on this element of the project design will be presented to the City Council .
