The appointment was the result of a petition signed by landowners in an area described as requiring drainage. In accordance with Section 9 of the Drainage Act, 1975, a site meeting was held at which it was determined that the area requiring drainage included: Parts of Lots 9 to 13, Concession VIII Parts of Lots 9 to 14, Concession IX of the Township of Kincardine. It was also determined that the petition complied with Section 4. The Preliminary Report was prepared and filed with the Township of Kincardine on August 27, 1981. Copies of the report were sent to every landowner within the area requiring drainage and to all affected public utilities. On September 17, 1981, a Council meeting was held at which time the Preliminary Report was considered. At the end of the subject meeting, Council gave notice to Paragon Engineering Limited to prepare a final report. Details of the present conditions and proposed work, which were outlined in the Preliminary Report, are presented in this report in Sections 2.0 and 3.0 respectively. 2,0 PRESENT CONDITIONS The area now petitioned for drainage works is smooth and gently sloping from east to west. The average slope of the drainage basin is approximately 0.85 percent. The majority of the drainage area is in agricultural use. The main crops are corn, mixed grains and pasture. The full potential of the land is not possible due to the absence of an adequate drainage outlet for surface water and tile drainage. We find that the drainage area comprises approximately 136 hectares (336 acres). Our investigation determined that there is an existing drainage system in the subject area which is known as the Sam. Lindsay Award Drain No. 1. Exact details of the drain are not available, however, information gathered during the site visit and subsequent field survey indicate that the Award Drain is located approximately in the same location as the proposed Main Drain of the Norman MacArthur Municipal Drain. The Award Drain is reported to range in size from 178 mm (7 inches) to 254 mm (10 inches) in diameter. Due to the deterioration of the Award Drain and its limited capacity as related to the area which it services, its benefit to the farmers within the drainage basin is limited. 3.0 PROPOSED WORK To improve the drainage, a closed drainage system with catchbasins to collect surface water is proposed. The new drain has been designed to accommodate the runoff from the watershed and will have sufficient depth to enable the Award Drain to be connected, if deemed desirable by the Engineer during construction, and to take care of any drainage that the old drainage works is carrying. sections as described below. 3.1 MAIN DRAIN The drainage work is divided into three The Main Drain is 2077 metres (6813 feet) in length and receives the runoff from approximately 99.6 hectares (246 acres). The drain crosses the 9th Concession Road at two locations and the 10th Sideroad once. The outlet for the municipal drain is at the south -west corner of Lot 9, Concession IX. This is also the location of the outlet of the Sam Lindsay Award Drain No. 1. 3.2 BRANCH A This section of the municipal drain services mainly the area north of the 9th Concession between Lots 9 and 12. Branch A is 921 metres (3018 feet) in length. The drainage area contributing to Branch A is approximately 34.6 hectares (85.5 acres). The outlet of Branch A is at Station 0 + 345.0 of the Main Drain. 3.3 BRANCH B This 42 metre (138 foot) drain extends from Branch A through a localized low area on Lot 10, Concession IX to the roadside ditch of the 9th Concession Road. This branch drains approximately 1.8 hectares (4.4 acres) and outlets at Station 0 + 137.0 of Branch A. 3.4 WORKING SPACE AND DISPOSAL OF MATERIAL In accordance with Sections 16 and 63, the designated working space for the closed drain shall be a strip of land centred on the course of the drain and 20 metres in width. The owners of lands on which construction is to be completed shall designate the access route to and from the working space. 3.5 DRAWINGS AND SPECIFICATIONS The following drawings are to form part of the engineering report: Sheet No. Description 1 2 Drainage Plan and Detail 'A' Drain Profile The special provisions and specifications of the drainage works construction are attached hereto. 4,0 ALLOWANCES In accordance with Sections 29 to 33, where applicable, of the Drainage Act, 1975, the allowances payable to owners entitled thereto were determined as outlined in Table 1 and as described below: 4.1 ALLOWANCES FOR DAMAGE (SECTION 30) This is compensation for any damage to trees, fences, land and crops occasioned by the disposal of material removed from the drainage works and as caused by obtain- ing a suitable access from public roads. Other allowances as specified in the Drainage Act, 1975, are deemed not applicable to the Norman MacArthur Municipal Drain. Allowances shall become due in accordance with Sections 62(3) and (4). 5 Owner MAIN DRAIN BRANCH A BRANCH B Evald Hansen TABLE 1 SCHEDULE OF ALLOWANCES NORMAN MacARTHUR MUNICIPAL DRAIN TOWNSHIP OF KINCARDINE Allowance for Damages Lot Concession (Section 30) Ken Scott Pt.13, Pt.12 VIII $ 585.00 Ralph Scott Pt. 12 VIII 165.00 Bob MacArthur 11 VIII 930.00 Don Maus 10 VIII 450.00 John McKay 9 VIII 45.00 Norm MacArthur 9 IX 810.00 TOTAL ALLOWANCES - MAIN DRAIN $ 2,985.00 John Campbell 11 IX $ 360.00 Evald Hansen 10 IX 780.00 Norm MacArthur 9 IX 75.00 TOTAL ALLOWANCES - BRANCH A $ 1,215.00 10 IX $ 90.00 TOTAL ALLOWANCES - BRANCH B $ 90.00 TOTAL ALLOWANCES - NORMAN MacARTHUR MUNICIPAL DRAIN $ 4,290.00 5.0 ESTIMATED COST OF DRAINAGE WORKS 5.1 ESTIMATED COST OF CONSTRUCTION An estimate has been made of the cost of the proposed work, as outlined in detail below. 5.1.1 Main Drain 1.

Should the actual cost of the work differ from the estimated cost, the actual cost shall be charged against the said lands and roads in the same proportion as the estimated cost. The total cost shall be assessed as benefit or outlet liability in accordance with the Schedule of Assessments. Injurying liability is deemed not applicable. In accordance with Section 26 of the Drainage Act, 1975, a special assessment has been made against the Township of Kincardine for the cost of constructing the drainage works across the road allowance. The special assessment is the increased cost of the drainage works due to the roadway. The special assessment shall be composed of the actual cost of this work less the cost for equivalent field drain costs plus administration costs. The special assessment shall not apply when pro- rating future maintenance costs. It is anticipated that a Provincial grant equal to one -third of the assessment on agricultural land will be received, and if so, the assessment on the agricultural land shall be reduced accordingly. Table 4 outlines the estimated net cost of the Norman MacArthur Municipal Drain. Note: For the purpose of Section 85, all lands assessed are agricultural unless marked thus *, as extracted from the last revised assessment roll. MAIN DRAIN Lot Approximate or Hectares Conc.
