• 40 Oppidan Concept Plan page 7 Utilities Municipal water and sanitary sewer services will need to be extended to the site. Water will need to be looped. The specifics of the design of these utilities will be analyzed, but the general routes are described in the concept plan materials. The area is not served by municipal utilities now, but they will be needed for any new development. This presents challenges both for connection locations and financing the improvements. As noted for the road issues, a large development for the entire area might be able to meet the challenges but the economic situation tells us that a development project that large is not likely. Therefore, we need to rethink how to meet these infrastructure needs. Sanitary sewer is shown connecting to the existing pipe in Woodridge Lane. An easement will be necessary, and to our knowledge the developer has not yet ascertained where it will be. It would involve negotiating with other property owners. The exact route will need to be determined. According to the narrative letter, water will connect to Ravens Court to the north. How it will loop through the project needs to be determined. Preferably, it would follow the same easement as the sanitary sewer line to Woodridge Lane and connect to the water service there. A loop to Woodridge has been discussed for years in order to improve water service there. 49/J Plan Requirements: Municipal Utilities • All new development must have sanitary sewer and water service. Possible exceptions prior to the availability of utilities include renovation of existing structures if the building code allows it without utilities. However, the preference is for all uses in the study area to have municipal utilities. • Several options exist for utility service, as described in this study document. West of Hodgson, the preference is for connection to the Woodridge Lane sanitary sewer. • Water trunk lines must be looped, and development must provide the looping. These issues must be addressed with the infrastructure plans for development. • Stormwater management design must incorporate filtration and infiltration elements. This could include such features as rain gardens, swales, dry creeks, infiltration chambers, and other ecologically based methods along with more traditional ponds and pipes. • Stormwater management ponds, if used, should be designed to be a site amenity, including appropriate landscape elements. Stormwater management is only reflected by three stormwater ponds on the concept plan. Large parking lots result in significant runoff and the traditional "pipe and pond" approach is no longer adequate. It is likely that infiltration facilities will be required as
