THAT Report PD-106 -90 be received; 2 . THAT Staff be authorized to select a consultant to undertake a Employment Area Market Study, to determine the optimum mix of employment area land uses and to rationalize the amount of industrial land at Courtice; 3. THAT Staff be authorized to investigate the alternative interim servicing schemes in consultation with the owners and the Region of Durham; 4 . THAT a copy of PD-106 -90 be forwarded to the Region of Durham Planning and Works Departments . 1. BACKGROUND 1. 1 On July 25, 1988 the Council of the Town of Newcastle directed Planning Staff to commence a Planning Study for the area south of Highway 401 between Darlington Provincial Park and Darlington Generating Station, known as Special Study Area 11 in the Durham Region Official Plan. � 9C� O REPORT NO. : PD- 106-90 PAGE 2 1.2 As part of the Study, Staff determined that the feasibility of servicing the Study area with sanitary sewer and piped water services was the paramount consideration. Subsequently, the consulting firm, Totten Sims Hubicki were retained to commence a servicing feasibility study. In addition, a Technical Advisory Committee was formed to review and provide input into the study. The Committee was comprised of two engineers from Durham Region, two planners from Durham Region and four members from the Town of Newcastle Planning and Public Works Departments . 1. 3 The scope of the study was to examine the feasibility and costs of extending sanitary and water services from Oshawa or Bowmanville to the Study Area. The study, however, did not address the layout or costs for internal services with the study as they are dependant upon the road configuration evolving from the Planning process. 1.4 Staff requested the consultant initially to consider three areas: the lands within Special Study Area 11, Courtice Industrial Park and the Ontario Hydro park referred to as areas 'A' , 'B' and 'C' respectively and shown on attachment No. l. The land area totaling approximately 620 hectares (1530 acres) . Subsequently, as a result of several Official Plan Amendment applications and the Durham Region Official Plan Review examining possible extensions to the Courtice Urban Area, two additional areas 'D' and 'E' were added to the study, bringing the total area of the study to 1290 hectares (3188 acres) . Areas 'A' , 'B' , 'D' and 'E' will be referred to hereafter as South Courtice. 1.5 On November 2, 1989 and January 17, 1990 the Technical 599 02 REPORT NO. : PD- 106-90 PAGE 3 Advisory Committee met to review the first and second drafts of the Study and provide comments . Subsequently, on February 20, 1990 the Final Draft was received. 2. THE STUDY'S FINDINGS 2 . 1 Land Use Scenarios 2 . 1. 1 In order to establish the ultimate demand for water and sewage treatment there are a number of assumptions on land uses for each area that have been made. The scenarios shown on Attachment No.2 are as follows: Area 'A' - Prestige Industrial - 220 hectares Open Space - 105 hectares Area 'B' - Prestige Industrial for lands south to the Highway 401, east of Courtice Road - 127 hectares - General Industrial for lands west of Courtice Road - 59 hectares - Open Space - 14 hectares Area 'C' - Prestige Industrial - 78 hectares - Open Space - 17 hectares Area 'D' - Residential, between Prestonvale Road and Townline Road - 95 hectares (density of 24 .7 units per hectare) - General Industrial, east of Prestonvale road - 352 hectares - Open Space - 43 hectares Area 'E' - Residential - 176 hectares Open Space - 4 hectares 599 03 REPORT NO. : PD- 106-90 PAGE 4 2 .2 Sanitary Sewage 2 .2 . 1 The various options for the treatment of sanitary sewage require the construction of pumping stations, forcemains, gravity sanitary sewers, and the requirement of additional capacity at the Port Darlington Water Pollution Control Plant (WPCP) in Bowmanville and/or the Harmony Creek WPCP in Oshawa. The required sewage treatment plant capacity for the South Courtice land is 41,027 cu.m. /day (9 . 04 Millon Imperial Gallons per day (MIGD) . The required sewage treatment plant capacity for Area 'C' is 3510 cu.m/day (0 . 77 MIGD) . 2 .2 .2 A breakdown of the costs are appended hereto as Attachment No. 3. Option 1: Treat the sanitary sewage from all the Study area including Area 'C' at the Harmony Creek WPCP. The cost: $ 44,424,000 . 00 Option 2: Treat the sanitary sewage from Study South Courtice only (A,B,D and E) at Harmony Creek WPCP. Treat the sanitary sewage from Study Area 'C' at Port Darlington WPCP. The cost: $ 44, 009,000 .00 Option 3: Treat the sanitary sewage from the Robinson Creek Watershed portion of South Courtice at the Harmony Creek WPCP. Treat the balance of the sanitary sewage from 599 0 /it REPORT NO • PD- 106 -90 PAGE 5 remaining Study Areas at Port Darlington WPCP The cost: $ 58,567,000 . 00 Option 4: Treat sanitary sewage from all Study Areas at the Port Darlington WPCP The cost: $ 58,856,000 . 00 Option 5: Construct a New Water Pollution Control Plant to treat sanitary sewage from all the Study Area. The cost: $ 47,032,000 . 00 plus land acquisition and environmental assessment study costs . 2 .2 . 3 Options 1 to 4 required an expansion to either the Port Darlington WPCP and/or the Harmony Creek WPCP, to provide sanitary sewer to the Study Area. It should be noted that Whitby-Oshawa-Courtice is presently serviced by the Harmony Creek WPCP and the Corbett Creek WPCP both of which will be at capacity when development of the present Regional Official Plan designated urban areas in Whitby, Oshawa and Courtice are completed. Given this, a new treatment plant will be required, eventually, to service lands in north Oshawa and north Whitby. 2 . 3 Water Supply 2 . 3 . 1 Water supply requirements became the most difficult component of the Servicing Study due to, among other things, the pressure zone configuration and the high demand placed by industrial land uses . Supply requirements have three main components: general 599 OD REPORT NO. : PD- 106 -90 PAGE 6 consumption (by households, industry etc. ) , fire flow (protection) and water storage (reservoirs) Water storage facilities are required in a water system to provide balancing flows during peak demand period, fire fighting, and to provide emergency storage in the event of failure of the supply works . 2 . 3 . 2 There are three pressure zones that traverse the Study Area. Area 'C' is located within the Bowmanville Zone 1, would be serviced by Bowmanville Water Supply Plant. The South Courtice lands are within zones 1 and 2, the Oshawa-Whitby-Courtice water system would be serviced by the Whitby and/or Oshawa WSP. Part of Area 'B' is located in a remote portion of Zone 2, where adequate pressure become questionable. 2 . 3 . 3 A number of options have been considered based on the pressure zones . It should be noted that the options would require the construction of booster pumping stations, feedermains, provide additional supply at the Bowmanville Water Supply Plant (WSP) and Whitby WSP. Additional storage will also be required for emergency and equalization. The maximum day demand for the South Courtice lands would be 69 ,930 cu.m. /day (15 .28 MIGD) . The maximum day demand for Area 'C' would be 3510 cu.m./day (0 .77 MIGD) . Option 1: Service Study Area 'C' from the Bowmanville WSP. The cost: $4,469,600 (assuming cost sharing of feedermain with other land owners) . $ 8,938,000 (assuming no cost sharing) . REPORT NO. : PD-106 -90 PAGE 7 Option 2: Service South Courtice (areas 'A' , 'B' , 'D' and 'E' ) from the Whitby-Oshawa-Courtice Water System. The cost: $54,500,000 .00 Option 3: Service South Courtice from a New Water Supply Plant. The cost: $61,540,000 . 00 plus costs of land acquisition, environmental assessment and water quality studies . Option 4: Service South Courtice from the Bowmanville WSP. The cost: $56,000,000. 00 A breakdown of the costs are appended hereto as Attachment No.4. 2 .3 .4 An evaluation of the options would indicate that Option 1 Area 'C' could be serviced from the Bowmanville WSP. Option 2 would appear to be quite feasible in terms of cost and the timing of the development. For example the development of the study lands will occur over a long period of time therefore the construction of the feedermain reinforcements and additional water storage can be phased in as development occurs . Therefore, there is little up front cost in the initial stages of development only feedermain extensions through lower Whitby-Oshawa- Courtice Area will be required. 599 C- % REPORT NO. : PD-106 -90 PAGE 8 Option 3 would require large up front capital expenditure to construct the majority of the necessary new works prior to the start of, development and would require an Environmental Assessment. Option 4 would have to be further investigated, since the lot size and limited site area of the Bowmanville Water Supply Plant would be a constraint. In addition, there would be significant up front costs for the plant expansion and long feedermains to the site. 2 .4 Storm Drainage 2 .4. 1 There are three major creeks that traverse the Study Area, Robinson Creek, Tooley's Creek, Darlington Creek. In order for these areas to develop Master Plan Drainage Plans will be required by the Town of Newcastle Public Works Department and Central Lake Ontario Conservation Authority. The Plan will examine the watercourse in detail within the Study Area and beyond to the ultimate outlet at Lake Ontario to determine the work required to permit development to proceed. This work may include channelization, erosion control measures detention or retention ponds to control the rate of run off. A Master Drainage Plan is presently being undertaken for the Robinson Creek Watershed. 2 .5 Planning Alternatives 2 .5. 1 In accordance with standard practices and in preparation for possible environmental assessment requirement the Report examines a number of 599 08. REPORT NO. : PD-106 -90 PAGE 9 alternatives for providing services to the Study Areas. 2 .5 .2 Alternative 1 - Do Nothing The first alternative suggests that simply nothing be done. No development would be permitted with the exception of the lands presently designated industrial (Area B) . This alternative would be unacceptable given need for additional serviced industrial land. 2 .5 . 3 Alternative 2 - Limited Development on Private Services The second alternative would allow for limited development on private waste disposal systems and drilled wells . This is presently the situation in Area B. This scenario would not allow for the future growth of existing industries and would attract low profile or less desirable industries . In addition, adequate fire protection becomes questionable. 2 .5 .4 Alternative 3 - Development of Area C The lands in the Ontario Hydro development are considered in this alternative. The report suggests that these lands can be serviced from the sanitary sewer at the Port Darlington WPCP and the water from the Bowmanville WSP. The report suggests that this alternative would be technically feasible and would be implemented at the following cost: 599 09 REPORT NO. : PD- 106-90 PAGE 10 Sanitary Sewage $ 4,250,000 . Water Supply $ 4 ,700,000 . $ 8,950,000. This capital costs for servicing this area would be $114,700 per hectare. 2 .5 .5 Alternative 4 - Development of South Courtice The development of Areas 'A' , 'B' , 'D' and 'E' would ultimately require the construction of a new sanitary sewer treatment facility and a major expansion to the Whitby Water Supply Plant. Major improvements to the feedermain network in the lower Whitby-Oshawa area would be required to convey water to the South Courtice Study Areas . The estimated cost of providing full urban services are as follows: Sewage Works $45,000,000 to $55,000,000 Water Supply $55,000,000 to $62 ,000,000 Total $100,000,000 to $117,000,000 It should be noted that the above costs exclude land acquisition requirements and the costs of environment assessment and water quality studies . The servicing requirements would be between $97,200 to $113,700 per hectare (exclusive of land acquisition and study costs) . The estimated time required to complete the necessary environmental assessment for the selection of an appropriate site, the preliminary design and detailed design and construction of works would be 599 10 REPORT NO. : PD- 106-90 PAGE 11 minimum of five years . 2 . 6 Phasing of Development for South Courtice 2 .6 . 1 All of the above noted alternatives are based on the ultimate development of the South Courtice lands . The sewage system option recommended by Totten Sims Hubicki would lead to the location, design and construction of a new sewage treatment plant in the Study Area. The report suggests that an expansion to the Harmony Creek WPCP could be undertaken to provide interim capacity for treatment of sanitary sewage in the South Courtice area with the sewage directed to the new facility in the ultimate stage. 2 .6 .2 A phasing strategy has been put forth by the consultant to minimize the up-front cost as well as allow for the servicing of certain areas in the nearer future. Based on the assumption that interim capacity is available in the Harmony Creek WPCP, two phasing options are put forth. One option would allow the development of Areas 'A' and 'B' only. The other would allow for the development of the lands situated in the Robinson Creek Watershed. 2 .6 . 3 Phasing Option 1 - Areas A and B The first phasing option areas 'A' and 'B' will be only allowed to develop. 'D' and 'E' will remain undeveloped until the ultimate scheme was implemented. Areas 'A' and 'B' were noted by 5 ) ) I1 REPORT NO. : PD- 106-90 PAGE 12 Planning Staff in the initial terms of reference as a priority. Under this phasing option, a pumping station would be required at the Tooley Creek Valley near the southern limit of Study Area 'A' with a forcemain to the Harmony Creek WPCP. Water supply would require the reinforcement of the feedermain network in Zone 1 Whitby-Oshawa area. This would be undertaken to suit the ultimate condition. (Refer to Attachment #5, appended hereto) . Under this phasing option the total estimated costs are as follows: Prior to development $ 18,200,000. Phased in construction $ 28,491,000. Total $ 46,691,000. It should be noted. that the pumping station and feedermain would be abandoned with the ultimate development servicing scheme. 2 .6 .4 Phasing Option 2 - Robinson Creek Watershed The second phasing option would allow the development of parts of Areas 'B' 'D' and 'E' which are located within the Robinson Creek Watershed as shown on Attachment No.6) . The total estimated costs are as follows: Prior to development $ 14,000,000 Phased in Construction $ 43 ,403,000 $ 48,403,000 5 99 REPORT NO. : PD-106-90 PAGE 13 This scenario would also limit the extent of industrial development permitted. Only portion of Area 'B' can be developed for industrial uses . Area 'A' (Special Study Area #11) could not be developed. 2 .7 Study Conclusions and Recommendations Totten Sims Hubicki made the following conclusions with regard to the servicing feasibility of the various Study Areas: a) South Courtice (Areas A,B,C,D) and Area 'C' could proceed independently. b) Area 'C' should be considered in conjunction with the servicing scheme for West Bowmanville Developments . c) The ultimate development of South Courtice (Areas A, B,D, & E) will require the construction of a new sanitary sewage treatment plant and a major expansion of the Whitby Water Supply Plant. The planning and design of these works should occur on a regional basis rather than isolated for this Study Area. d) An expansion to the Harmony Creek WPCP could be undertaken for the treatment of sewage from South Courtice lands on an interim basis . e) In order for the Region to provide an interim allocation of plant capacity at Harmony Creek WPCP, there needs to be confirmation of a technically suitable and environmentally viable site for a new treatment facility. This requires an Environmental Assessment. J 1 REPORT NO. : PD- -90 PAGE 14 f) In order to determine the feasibility of expanding the Whitby Water Supply Plant, to the ultimate capacity of the South Courtice lands, an Environmental Assessment is required. g) Major improvements to the water feedermain network through Oshawa and Whitby is required to service the South Courtice area. h) Development of the lands at the easterly end of Area 'B' , which is currently designated Industrial, should be restricted due to difficulties in providing municipal water to these lands . 3. COMMENTS 3 . 1 The ultimate servicing scheme for South Courtice would require the construction of a new sewage treatment facility and expansion of the Whitby WSP to provide service to the entire study area. However, it would be some time before this scheme is given the proper approvals and before the construction is complete. The Regional staff has indicated that a major plant facility such as the sewage treatment plant would be designed in such a manner to handle requirements well beyond the Official Plan time horizon. As such a new sewage treatment plant in South Courtice would be designed and the trunk services sized in such a manner to service lands not only in Courtice but in north Oshawa and potentially north Whitby. 3.2 Based on current available industrial land and the historic absorption rates of industrial lands in the Town, it appears there is sufficient lands for industrial development on a short term basis . On a Regional basis, however, there is limited industrial land with Highway 401 exposure. It is staff 's view that the Regional industrial land absorption rates are significant to warrant the consideration of designating more industrial land in the Official Plan. 599 i REPORT NO. : PD- 106-90 PAGE 15 Given that the major capital costs to service these lands can only be justified Regional need basis, Staff recommend that an Employment Area Market Study be undertaken to investigate the unmet need for serviced industrial lands in Courtice in the context of the industrial land requirement for Durham Region. This Study should investigate the anticipated timing of development of industrial lands across Durham Region. It should also examine the optimum mix of specific industrial and related land uses including light, prestige and business park type uses, which would ultimately establish attractive and marketable employment area. The Employment Area Market Study is a fundamental undertaking in relation to the South Courtice lands and considerations underway through the Durham Region Official Plan Review. The firm of C.N. Watson and Associates Ltd. has estimated the cost of such work at $15,000 to $20,000 . A group of landowners in the Study Area has agreed to cover the costs of this work. 3 . 3 The Report offers two interim servicing solutions which would permit a substantial portion of the Study Area lands to commence development utilizing capacity from the Harmony Creek WPCP and the Whitby WSP. To receive such an interim allocation, the Region would need to be satisfied that technically suitable site is available for the sewage treatment plant and that an environmental assessment be conducted to expand either the Whitby WSP or the Bowmanville WSP. The investigation of the interim options and the development of a suitable financing scheme among the benefiting landowners will require further investigation. To this end, staff have held preliminary discussion with Regional Staff. 599 1 � REPORT NO. : PD- 106-90 PAGE 16 3 .4 It is apparent from the Study, that it may not be possible to bring any of the lands in South Courtice on stream for industrial development proposal in the immediate futures. Given this, there are two important considerations for the Town's short term economic development strategy: i) the only location in the Town to bring a significant amount of serviced industrial land on stream in the immediate future is in the Bowmanville Urban Area. The Town's marketing efforts should focus here and attempts should be made to co-ordinate the development of these lands. ii) the high-profile frontage in the Courtice Industrial Park will continue to be utilized by low-profile industrial users until water and sanitary sewer services are available. Given this, the Town should consider revisions to the industrial zoning in the Courtice Industrial Park to prevent some undesirable industrial uses from occupying the high profile areas . 4. CONCLUSIONS The South Courtice Servicing Feasibility Study provides an overview in terms of the time and cost of the servicing requirements for this area. It is important that the Town undertake a comprehensive examination of the industrial land requirement for the Region and rationalize the need for the industrial designation in this area. Staff must also investigte the interim servicing option with Region and interested landowners . 599 1 h REPORT NO. : PD- 106-90 PAGE 17 Respectfully submitted, Recommended for presentation to the Committee Franklin Wu, M.C.
