The 28 foot width also signals to motorists that the street provides a "lesser function" than adjacent collector streets and therefor will tend to guide traffic along the adjacent collector streets. Special Case Street: Femwood Court, Ingerson Court These streets serve less than 5 residential properties each and are dead-end roadways less than 500 feet in length. The proposed width of 24 feet is adequate for two way traffic, emergency vehicles and City maintenance when no parking is allowed. One way traffic is possible when vehicles are parked on one side of the road only. Due to the low number of residents served by these streets and the availability of off street parking, the parking restriction is not anticipated to cause any hardship. Existing right of way allows for standard width streets in both of these cases in this project however there is not adequate right of way for standard cul-de-sac bulbs. The report recommends that 30 foot radius bulbs be constructed at the end of both of these streets. The narrower width provides for less runoff, reduces construction and maintenance costs and provides a passi ve traffic calming effect which is generally desirable on local residential streets. The 24 foot width also signals to motorists that the street provides a "lesser function" than adjacent collector or local streets and therefor will tend to guide traffic along the those streets. Project Cost Implications For each 4 foot of street width reduction from 32 feet, the City can expect to realize approximately $18.00 in project cost savings per foot of roadway length. For Example, the cost to reconstruct Carlton Drive (1450 feet long) at the proposed 28 foot width is approximately $205.oo/ft or $300,000.00. If Carlton Drive is constructed to a 32 foot width, the estimated project cost is $326,000.00. Prooosed Storm Drainal!e Imorovements A. Storm Sewer The proposed improvements include storm sewer construction in all roadways scheduled for reconstruction. Storm sewer improvements include catch basins along curb lines, trunk sewer and outlets into the proposed Regional Ponds described below. Some existing storm sewer is located in Fernwood Court and Fernwood Street however the report has assumed that these facilities will be replaced. The existing storm sewer condition and location will be field surveyed as a part of final design. If the sewer is found to be in a usable location, of good condition and adequate capacity, the plans will provide for the reuse of the existing storm sewer. The proposed storm sewer improvements are based upon collecting street runoff 4
