design and cost estimate, and for determining the cost sharing between the owner(s) served by the bridge and the upstream lands and roads.
Pursuant to Section 26 of the Drainage Act, the Public Utility or Road Authority is responsible for all increase in cost to the drainage works due to the existence of their services or roadways. This requirement has been reflected in the following Bridge Cost Sharing table related to sharing of future maintenance costs for the access bridges. This provision shall apply to the to the Mount Royal Drive (Br. 4), Casgrain Drive (Br. 6), and Sutherland Avenue (Br. 17) road crossings which are owned by the City of Windsor.
Where a bridge structure has increased top width beyond the standard 6.10 metre (20.0 ft.) top width, or any other special features, all of the increased costs resulting from same are assessed 100% to the Owner of the lands served by the bridge. Should concrete, asphalt or other decorative driveway surfaces over a bridge culvert require removal as part of the drainage works, these surfaces should also be repaired or replaced as part of the works. Likewise, if any fencing, gate, decorative walls, guard rails or other special features exist that will be impacted by the maintenance work, they are also to be removed and restored or replaced as part of the bridge maintenance work. However, the cost of the supply and installation of any surface material other than Granular “A” material, and the cost of removal and restoration or replacement, if necessary, of any special features, shall be totally assessed to the benefiting adjoining Owner(s) served by said access bridge.
XII. FUTURE MAINTENANCE
When maintenance work is carried out in the future on the open drain portion, the cost for said future maintenance shall be assessed in accordance with the attached Schedule of Assessment excluding any Special Benefit or any Benefit shown to the individual private lands. When future maintenance work is carried out, the assessment to the affected Owners shall be based on the actual future maintenance cost shared on a pro-rata basis with the block assessment values shown in this assessment schedule. Since the upstream areas are assessed as blocks pursuant to the Drainage Act, the costs to each block shall be paid in accordance with City of Windsor provisions for dealing with Municipal drainage work costs.
When maintenance work is carried out on any public road or other bridges on lands owned by the City of Windsor in the future, we recommend that the cost be assessed 100% to the City. When maintenance work is carried out on any primary landowner bridges in the future, we recommend that part of the cost be assessed as a Benefit to the abutting parcel served by the access bridge, and the remainder shall be assessed to the upstream lands and roads based on their affected area and block assessments as set out in the attached Schedule of Assessment. The share for Benefit and Outlet Liability shall be as set out in the Bridge Cost Sharing table below. Since Bridge 2 is a shared access bridge and secondary access for 080-140-00100-0000, we recommend that 100% of the cost of future maintenance to their share of the bridge be assessed as a Benefit to the abutting parcel served by the bridge.
The City of Windsor requires that all new culverts that are installed be reinforced concrete pipes. We recommend that legal crossings adopted in this report be replaced with pipe sizes and design grades as shown in the plans.
