2) Additional survey points needed to update the basemap on the southwest corner to show existing right turn only lane that was not shown on the original basemap provided by the City. 3) increase in length of survey along the east leg to accommodate extension of eastbound acceleration lane. 4) Increase in general scope of overall topo due to the aging of the aerial topography (additbn of rross section to confirm street cross slope due to recent overlay, etc.). 5) Additional survey points north leg of the intersection for possible northbound acceleration lane and for evaluation of proposed encroachment into Orloff Park to keep U-turning vehicles from crossing Into northbound right turn only lane. 6} Additional survey points at new conform bcations. 7) Additional survey points to locate existing traffic signal equipment. KHA has spent additional time modifying the topographic base mapping provided by the City based on the new survey shots provided by MPS. Additional Deliverables: f) Updated topographic mapping with survey points TASK 3 -PROJECT RESEARCH AND COORDINATION At the request of the City, KHA will coordinate with Project Land Surveyor and Landscape Architect to include design of the entry way at Orloff Park. TASK 4 -CONCEPTUAL DESIGNS At the request of the City, KHA has prepared two exhibits for the widening of the east side of Santa Rita Road rarth of Valley Avenue. The widening will allow a U-turning vehiGe on Santa Rita Road to complete the movement without encroaching into the northbound acceleration lane provided for the westbound to northbound right-turn maneuver. One of the exhibits showed moving the curb 3 (three) feet towards the park based on "rule o(thumb" U-rum template end the second exhibit showed moving the curb 9 (nine) feet towards the park based on the AutoTURN turning template. Per the meeting on October 2, 21x18, KHA has refined the second option, the relocetlon of the curb 9 (nine) feet towards the park, with a striped tighter radius, to slow the westbound to northbound turning traffic in the vicinity of the crosswalk. The additional scope is as follows: 1) Prepare conceptual plan alternatives for the widening of Santa RNa Road north of the intersection with Valley. 2) Refine the 9 (nine) feet widening altematrve to slow westbound to northbound traffic. 3) Refine medians end lane widths to allow for left tum truck movements without pulling curbed portbn of the median so far from the crosswalk.
