Standard Services and Work Plan Project Description Reche Canyon Road currently connects to Washington Street at Hunts Lane Washington Street at `T' intersections approximately 700 feet apart. Washington Street is an East/West, four -lane roadway with two lanes in each direction. Both Reche Canyon and Hunts Lane are two lane roads connecting to Washington Street at offset signalized intersections in a North/South direction. The proposed improvement will realigned a portion of Reche Canyon intersecting Washington Street at Hunts Lane at a four way intersection while the old alignment will also remained in operation intersecting Washington street at a T intersection. Project Understanding It is our understanding that the City of Colton desires to realign approximately 1200 feet of Reche Canyon south of Washington Street, and still maintain the old alignment thus forming a Split Y on the Road. The proposed Reche Canyon alignment will intersect at Hunts Lane. This will necessitate a traffic signal modification and new traffic signals to n accommodate the new traffic movements at that new Intersection. In addition, the striping for the existing Reche Canyon will also require re- design to accommodate the expected traffic movements on the new and old alignments. It is our understanding that LAN engineering has developed 3 alternatives for the old and new alignments and has selected one of the alternatives as the "Optimum" alternative. The "Optimum" alternative at the intersection with Hunts lane consists of 2- 12 -foot thru lanes, two dedicated right tum lanes, a 12 foot and 16 foot lane. However, this alternative proposes to cul-de-sac the Old Reche Canyon Alignment, which we do not believe is what the City desires. LAN'S Alternative 2 leaves the Old Reche Canyon Alignment in place just the way it currently functions, and the New Reche Canyon alignment would offer two south bound lanes with one dedicated westbound tum, two thru north bound lanes and two lanes for eastbound turns. This alternative also offers two lanes on the eastbound and southbound alignment for northbound and southbound traffic movements. Alternative 3 it the same as Alternative 2 as far as traffic movements at the Old and New aliments. The difference lies in the way the Y -split is handled. While Alternative 2 allows the traffic to split at the Y northeast and northwest without the need for a traffic signal, Alternative 3 proposes a traffic signal at the Y. It is our understanding that the City of Colton desires to keep the Old Reche Canyon Alignment in operation. Therefore, all the alternatives would have to be re -analyzed and discussed with the City in order to develop an alternative that would achieve the City's goal .oco ��".._.. 2139 Mount Vernon Avenue, Suite 210.
