The site is located between Franktown and Copeland Roads to the south and north, respectively, and is bounded by rural farms to the east and the Heron Lake rural residential subdivision to the west (Map 1). The site is currently the active Riverbend Golf Course. The proposed draft plan of subdivision includes removing a short play golf course, realigning six of the current 18-hole golf course to provide a greater setback from the Jock River and adding 26 rural residential lots, with a minimum lot size of 0.8 hectares (Map 2). A typical house will have a footprint area between 200 and 300 m2 with four to five bedrooms and a garage of 50 m2. Each home will be serviced by an individual water well and private sewage system with a capacity of 3500 L/day. Surrounding land uses to the site include: Rural farms to the east, south and north of the site; A 200 metre wide deciduous forest to the north of the site, north of Copeland Road; and, The Heron Lake rural residential subdivision to the west of the site, with active agricultural land and the DND Dwyer Hill Training Centre further to the west, east of Dwyer Hill Road. The site is designated General Rural Area on Schedule A of the 2003 City of Ottawa Official Plan (City of Ottawa, 2003). There are no Provincially Significant Wetlands, Rural Natural Features or Natural Environment Areas in proximity to the site. Schedule K in the Official Plan identifies a landform feature in the vicinity of Franktown Road, which are the Jock River Stromatolites, a Provincially Significant Earth Science Area of Natural and Scientific Interest (ANSI) discussed in Section 3.2. The former Region of Ottawa Carleton’s Natural Environment System Strategy did not identify any Natural Areas in the general vicinity of the site (Brunton, 1997). The Jock River is the dominant natural environment feature in the general area. The site is located within the north-central portion of Reach 3 of the Jock River, as identified in the Jock River Watershed Management Plan (RVCA, 2001). The Watershed Management Plan identified environmental features for Reach 3 of the River, but only the Jock River Stromatolites are in proximity to the site (OMNR, 2009). The Provincially significant Richmond Fen is in the southeast corner of Reach 3, west of Richmond, and the Marlborough Forest is along the south portions of the Reach, south of the Jock River. White sucker spawning at the Ashton Dam at the upstream end of reach 3 is reported by RVCA (2001). In addition to the Jock River Stromatolites, RVCA (2001) also identified an Earth Science ANSI along Franktown Road in proximity to the Richmond Fen, approximately 5.5 kilometres to the east of the site. 08/11/09 ENVIRONMENTAL IMPACT STATEMENT – RIVERBEND GOLF Page 1 MUNCASTER ENVIRONMENTAL PLANNING INC. The Watershed Management Plan notes that riparian vegetation is lacking in some stretches of Reach 3 and the water quality is impaired with high counts of nutrients and bacteria. Flow and associated water depths are limited in the summer months with much of the Reach reported as non-navigable (RVCA, 2001). Improvement of riparian vegetation was a recommendation in the Watershed Management Plan for the general area of the site. In summary, the Jock River in the vicinity of the site provides warmwater aquatic habitat, with limited flows in the summer months. The identified natural environment features of special interest in the Jock River system are not in proximity to the site outside of the Jock River Stromatolites. In addition to the aquatic habitat and other functions of the Jock River system, the Dowdall Municipal Drain joins the Jock River from the west in the middle portion of the site. This Environmental Impact Statement (EIS) has been completed due the presence of fish habitat within the Jock River and the Dowdall Municipal Drain and the Earth Science ANSI at Franktown Road. In addition this report contains a Tree Conservation Report, following the Revised Guidelines for City of Ottawa Tree Conservation Report, found at www.ottawa.ca/residents/healthy_lawns/forestry/urban_ tree_conservation/guidelines_en.html. 1.1 Scoping the Environmental Impact Statement The EIS was prepared in accordance with Section 4.7.8 of the City of Ottawa Official Plan (City of Ottawa, 2003), following the standards of the Natural Heritage Reference Manual (OMNR, 1999) and the Environmental Impact Statement Draft Guidelines for the former Region of Ottawa-Carleton (RMOC, 1998), and includes the components of an Environmental Impact Statement as identified in Section 4.7.8.2 a) through h) of the City of Ottawa Official Plan (City of Ottawa, 2003). The major objective of this EIS is to determine the anticipated impacts associated with the proposed change in land use on the significant features and functions of the Jock River and Dowdall Municipal Drain systems, along with the Earth Science ANSI and, as required, to provide the methodology to mitigate any negative impact, or enhance positive impacts, on the significant natural heritage features and functions in the area. To attain this objective, the original conceptual draft plan of subdivision was reviewed and recommendations made for revisions based on field observations of the features and functions of the natural environment. In addition, mitigation measures are presented in Section 6 of this EIS to reduce the potential for impacts on the features and functions. The following items were identified for particular attention, recognizing that many of these issues are interrelated: what are the anticipated direct and indirect potential impacts on the adjacent fish habitat within the Jock River and Dowdall Municipal Drain?; what setbacks are required to provide
