It is the recommendation of this report to install service lines with a curb stop at the property line for all homes which are not yet connected to City water. This would include homes in the area where water main was previously extended as well as homes in the area where new water main is proposed. Services will be installed via directional drilling technology to avoid impacts to the roadway. Category A improvements are divided into two types as listed below: A-' - Extension of new water main and services with no associated road work. A-2 _ Water main already exists. but new services are proposed. with no associated road work. B. FULL RECONSTRUCTION OF THE STREET SECTION: The majority of Category B streets have no remaining salvage value in the existing bituminous or gravel subbase. In other words. no portion of the road section could be reused in the restoration of the street. A complete reconstruction of the street section is needed. . Where curb exists. this will mean full removal and replacement of the curb and gutter along with the street section. Saving the existing curb. as seen in Category C. was contemplated but proved to be impractical and not cost effective in these instances. For the same reasons. saving portions of the pavement. or patching, also proved to be counterproductive. The largest factor in the lack of salvage value of these streets is drainage issues in the subbase. Therefore. the proposed improvements include additional catch basins and storm sewer where it is both needed and reasonably feasible. Additionally, in the areas where there is currently no existing curb, such as Peltier Lake Drive. concrete curb and gutter will be constructed which will improve the drainage of the street and consequently the subbase. In the Robin Lanel Cardinal Drive area there is remaining salvage value to the roads. However, the road improvement type is dictated by the addition of water main in this dense neighborhood. Options involving the drilling of water main were explored in order to determine if it was possible to supply this neighborhood with water without having to fully reconstruct the road. Two options were examined. Option one would be to directionally drill the main within the existing front yard utility easement. The second would be to drill the main within the utility easement in the backyards. These options were ruled out due to the following prominent issues: Front yard easement . The homes within this area have smaller setbacks than in other areas. This would make the area harder to work in and therefore add cost to the project. . The yards. driveways. and landscaping within the easement would suffer extensive disturbance and need to be replaced. . The "runs" are too short to make directional drilling cost effective.
