one ten-foot sidewalk area. The adjacent property will have to provide another parking lane and an additional ten-foot sidewark area. This will be required because the D.K. Development Company property will have 90 to 95 dwellings using this roadway, and it will also have to be avail- able for emergency vehicles. Also, there may be a significant time lag between the development of the two properties (see the section regarding the Williamson Act). The terminus of this or any other roadway will have a cul-de-sac or turn- around area with a minimum curb radius of 40 feet. Offsite improvements will also be required because of the development of the property. The major improvement will be the installation of a traffic signal at the intersection of Woodside Road and Kentfield Avenue. The most equitable way to provide the signal is to have each property developer pay a proportional share of the price. A rough estimate for the cost of the signal is $200,000, and D.R. Development Company has 22,7 percent of the land in the Horgan Tract. This would mean $45,390 as their share of the traffic signal. The major shortfall with assessing properties this way is that the City does not have $154,610 which is needed for the rest of the signal, and there may not be any further development within the Horgan Ranch for many years. The signal will have to be provided, or there will be a significant traffic bottleneck at this new intersection and at the existing Atherwood Avenue intersection, An alternative would be to limit the number of dwellings within the D.R. Development Company property to where the impact would be minimal and no traffic signals would be required. Other offsite improvements include the closing of the median at Atherwood Avenue and possible lane ~rking and channelization on Woodside Road. RecotmIlendations: 1. Horgan Avenue and Kentfield Avenue will have a 60-foot right-of- way for the majority of its length into the ranch area. 2. The remainder of Horgan Avenue, Kentfield Avenue, and the loop connector will be a standard 54-foot right-of-way street. 3. Parkwood Way from its existing terminus to Kentfield Avenue will be a standard 54-foot wide public street. 4. All other public streets within the Horgan Ranch will be standard 54-foot wide streets. 5. Private streets will have a minimum of 25 feet of width curb-to- curb, and there will be at least 2.25 parking spaces per unit when there are private streets. 6. The first property to develop off Kentfield Avenue would construct rwo-thirds of a street consisting of two twelve-foot travel lanes, an eight-foot parking lane, and one ten-foot sidewalk area. - 3 - E-xH16 rr (.(1."-7
