4 Project BackgroundLa Pata Avenue included on Orange County Master Plan of Arterial Highways (MPAH) since 1963La Pata and Camino Del Rio shown on City of San Clemente General Plan since 1982 and Talega and Forster Ranch Specific PlansThe existing La Pata Avenue built in the 1970s as a "dead-end" landfill access roadProject initiated in Three years of coordination with City and resident groups resulted in an alignment responding to concerns of proximity, light and glare, and aesthetics.
6 Project Purpose and Objectives Implement Orange County MPAH, Circulation Elements of San Clemente and San Juan Capistrano, and Specific Plans for Talega and Forster RanchProvide north/south access for local trafficImprove access to schools, commercial areas, and recreational amenitiesImprove emergency accessReduce Vehicle Miles Traveled (VMT) and greenhouse gas emissions
7 Project Purpose and Objectives (continued) Facilitate local inter-community circulationProvide increased network capacity to support the forecast travel demand for the 2035 design yearMinimize impacts to utility transmission infrastructureMinimize impacts to existing residential land usesMinimize impacts to the natural environment
9 Proposed ProjectWiden La Pata Avenue from three to five lanes from Ortega Highway to the existing road terminus at the Prima Deshecha Landfill (PDL) – a distance of 9,600 feetConstruct four new lanes from the existing PDL terminus to Calle Saluda – a distance of 10,100 feetExtend Camino Del Rio, as a four-lane roadway, from its existing terminus to the proposed Avenida La Pata – a distance of 1,700 feetEstimated Total Cost: $77,368,000
10 Proposed ProjectLighting will be provided along Camino Del Rio, on La Pata between Calle Saluda and Camino Del Rio, and on La Pata north of the landfill entrance to the project limits.Sidewalks will extend along Camino Del Rio to La Pata and on the west side of La Pata from Calle Saluda to Camino Del Rio and from Vista Montana north to the project limits.Bike lanes will be provided along both La Pata and Camino Del Rio. San Clemente’s off-road bike path east of La Pata will be extended north to the city limits.The roadway project requires grading of 9 million cubic yards.3 million cubic yards are required to balance the roadway. The remaining 6 million cubic yards are required to stabilize a large landslide complex. All earthmoving is balanced on site.

21 Significant Unavoidable Impacts Traffic:2016 – I-5 Northbound ramps/Avenida Pico and I-5 Northbound direct on-ramp from Crown Valley Parkway2035 Without SR-241 Scenario – I-5 Northbound ramps/Avenida PicoImprovements currently being planned and funded by M2 will reduce impacts.Air Quality: Construction Emissions – CO, ROC, NOX, PM10, and PM2.5Contributions to regional air quality thresholdsLocalized Impacts – Worst Case AssumptionsNoise: Increased traffic on Camino Del Rio forecast to exceed 65 dBA at 6 modeled locationsSeveral 4-foot noise walls are recommended and will reduce significant impacts.
