Please find enclosed herewith plans for three signalized intersections and a storm drain. Signal loops and traffic control markings on the pavement that are destroyed during trenching will need to be replaced in kind in accordance with Caltrans standard specifications and standard plans. Trenches should be backfilled in' accordance with Los Angles County Public Works Standard Drawing 3081-0 (copy enclosed). Jetting or flooding of backfill material will not be allowed; all backfill shall be mechanically compacted in lifts of eight (8) inches or less.

If soil testing is performed it needs to be done so at 1.,000400t intervals and should identify the type of soil in accordance with'the Unified Soil Classification table and include such information as: maximum density, optimal moisture content, and existing moisture content. The replacement thickness of asphalt concrete. pavement shall be 1" thicker than the existing pavement; this will be field determined when the trench is open. Regarding proposed placement location for the sewer main, itis recommended that you avoid traffic lanes wherever possible, but if the sewer must go in a traffic lane, every, effort should be made to place it in the center of the ultimate traffic lane. The ultimate traffic lane is determined by applying the dimensions found on the City's adopted cross-section for the street in question with regard to the proposed sewer location.

Advertising for construction for the projects is anticipated to be May 1996 for Project No. 3, June 1996 for Project No. 1 and July 1996 for Project No. 2. In order to meet these short time lines, it is important that we obtain information from you relative to existing City facilities and other issues impacting the construction zones for these projects. These items may include, but not be limited to, the following: a. Proposed roadway construction or maintenance projects b. Existing underground City facilities, including traffic signal mechanisms, storm drains, or other improvement infrastructure . c. Private development projects in the planning process, final design preparation, etc. e.

Special Condition No. 1 of the encroachment permit states that all work shall be performed per the Standard Specifications for Public Works Construction, ".Greenbook." The specifications in the "Greenbook" state that all surface improvements removed shill be reconstructed by the contractor to the same dimensions. , CVWD has created a safety hazard by allowing the contractor to construct a raised asphalt lip, creating a very unstable wheel path for vehicles. An additional problem that may occur is water accumulation at the asphalt lip. This will increase the risk of hydroplaning and cause the deterioration of the asphalt road surface. The City of La Quinta requests that the CVWD remove the feathered overlay, and complete. a "butt" joint overlay in the trench created by CVWD's operations. If you have any questions regarding this matter, please call me at (619) 777-7100. Sincerely, Thomas P. Genovese City Manager TPG/HG/hg cc: Dawn Honeywell, City Attorney Chris A.

Hector was asked to put the paving requirements in writing. Hector declined to do this. Steve Robbins called LaQuinta about the paving problem. The matter was not resolved. 1/24/97 Field meeting referred to in the letter mentioned below 1/27/97 Letter to CVWD from Petar Artukovich Construction Company F regarding the City of LaQuinta, LaQuinta's encroachment permit, and La Quinta's request for a "buttjoint" for the paving cap in La Quinta. 1/27/97 Steve Robbins continued talking to representatives of LaQuinta. The matter was not resolved. 1/27/97 Gregg Green, CVWD inspector, again asked Hector to put LaQuinta's paving requirements in writing. Again this was not done. 1/27/97 Mr. Tom Levy called the City of LaQuinta to resolve the problem. He was unable to talk to the city manager until 1/28/97. 1/28/97. Washington St. was paved with a 10 foot wide cap starting at I a.m. and ending at 9:30 a.m. r 2/6/97 The City of Palm Desert Encroachment Permit required a butt join as shown in their permanent resurfacing details included in their encroachment permit, see Attachment G. The city of Palm Desert's inspector also notified the contractor on the first day of contraction in Palm Desert that a butt join was required. Therefore, the contractor placed the base paving below the existing surface elevation to achieve a butt join on the inside portion of the trench. The outside portion of the trench was feathered out to the curb and gutter. —> The Green Book reference on "same dimensions" in permanent resurfacing is as follows: "306-1.5.2 Permanent Resurfacing. Unless otherwise shown on the Plans or in the specifications, all surface improvements damaged or removed as a result of the Contractor's operations shall be reconstructed by the Contractor to the same dimensions, except for pavement thickness, and with the same type materials used in the original work. Trench resurfacing shall be I inch greater in thickness than existing pavement." (Attachment I is a copy of the Green Book page containing this reference). The pictures included in Attachment H were taken of January 31., 1997 just north of the intersection of Fred Waring Drive and Washington Street. You.can see that on the inside edge of the overlay the existing street is decomposing. The area of the existing street that is under the overlay was in a similar state of decomposition. The trench width was 4 feet wide. The overlay is 10.5 feet wide. Therefore the city of La Quinta received 6.5 feet of additional street improvements than the contractor would have had to provide. The overlay provided by the contractor meets the requirements of the Green Book section 306-1.5.2 above plus an additional 6.5 feet of improved road surface. A drawing was not included with the City of LaQuinta's Encroachment Permit which was issued to the contractor. The encroachment permit does not require a butt join. The permit does not require a particular type of final paving. The La Quinta City inspector, Hector Guzman , was present on the project site during mainline operations within the city of La Quinta. The dates of mainline construction within La Quinta are shown in Table 2. Hector witnessed the base paving of the trench during mainline operations. Hector did not question the height of the base paving, which was flush with the street. The first time that Hector requested a buttjoin .final A.C. cap was on January 24. If this request had been made earlier the base paving would have been left below the existing surface elevation as was done in Palm Desert. At the time the request for a butt join . was made, the base paving was complete; in order for the final cap to have a butt join the base paving would have to be ground down. Additional work is required to provide a buttjoin after the base paving had been allowed to be installed without being recessed. 2 2/6/97 Table 2.
