Crome, MCIP, RPP Franklin Wu, Director of Planning Services Chief Administrative Officer CP/df/nl 18 June 2013 CORPORATION OF THE MUNICIPALITY OF CLARINGTON 40 EMPERANCE STREET, BOWMANVILLE, ONTARIO L1C 3A6 T 905-623-3379 REPORT NO.: PSD-044-13 PAGE 2 1. BACKGROUND 1.1 A letter and petition dated May 28, 2013, was submitted by Mr. Franklin regarding noise levels for the properties on the west side of Vivian Drive, abutting Trulls Road. The letter states that the study dealing with noise for this development was done in the past and "since all the dwellings have now been constructed and occupied, residents have raised concerns with the noise reduction means provided, namely a chain link fence and cedar hedge". The letter also requests a further noise study be completed as traffic has increased over the last two years. The subdivision was marketed as Courtice Homestead. 2. DISCUSSION 2.1 The noise attenuation study for the referenced subdivision was prepared in December 2007 with revisions completed in January and June of 2009. The study was based on a forecasted average annual daily traffic (AADT) volume for Trulls Road of 16,000 vehicles on a four (4) lane road. Based on 2009 counts and allowances for yearly increase in traffic volume, the current AADT on Trulls Road is estimated to be approximately 4500 vehicles on a two (2) lane road, well below the forecasted volumes utilized in the study. The number of vehicles forecasted for Trulls Road is considered to be well in excess of existing actual trips and the noise study and its updates are considered to be valid. 2.2 In keeping with the Council approved Noise Attenuation Design Guidelines, the use of a noise fence along the arterial road, Trulls Road frontage, was avoided through the subdivision review and approval process. The front lawn, veranda, or combination thereof depending on the model, were used to provide the minimum required amenity area for noise mitigation. The lots on the west side of Vivian Drive are 13.5 and 15 metres wide. The front yard setback to the dwelling was increased from the more typical 4.0 metres to the dwelling to 7.5 metres and 6.5 metres respectively to provide for the minimum 56 m2 MOE required amenity area protected from noise. 2.3 The subdivision agreement required the Owner to advise the purchasers of the 13 lots abutting Trulls Road "that in order to achieve acceptable noise attenuation levels . the outdoor amenity area is located in the front yard and/or veranda of the dwelling." The developer has recently confirmed that this did occur during closing of all the lots in question. 2.4 Conditions of draft approval required the recommendations of the noise report to be implemented; including the use of warning clauses registered on-title advising that sound levels from road traffic may interfere with some activities of the dwelling occupant. The developer was required to install 1.2 m high chain link fence abutting Trulls Road and to plant cedars having a minimum height of 1.8 metres. Furthermore, through the purchase and sale agreement, landowners were advised that they would be responsible for maintenance of the hedge. REPORT NO.: PS®-044-13 PAGE 3 2.5 The chain link fence installed by the developer is actually 1.5 m tall and the cedars vary in height. The chain link fence and cedars were not intended to provide for noise attenuation, but rather delineate the property line and provide for a more natural screen to the rear yards. The cedars were planted late last fall and need time to take root and fill out. Although that aspect of the subdivision has not been a formally accepted and put on maintenance, municipal staff have recently viewed the planted cedars and determined that they have been planted consistent with the approved plan. 2.6 Based on the 2009 noise study, should a fence be used to attenuate noise, the fence would need to be 2.75 m (9 ft) high to reduce rear yard noise levels to meet Ministry of Environment requirements. Approximately 210 metres offence would need to be constructed to cover the full length of the Trulls Road frontage, as well as wrap around sections to tie back into the dwellings at the corners. A 2.75 m tall noise fence is 0.6 to 0.95 m taller than typical noise fences and has an approximate cost of$375 per metre. Therefore to install noise fencing now would cost in the range of $80,000. In addition, there would be cost to removing the existing chain link fence. 2.7 The subdivision was approved with amenity areas in the front yard and/or veranda of the dwelling in compliance with Ministry of Environment criteria for noise. Based on the requirements of the subdivision agreement, the purchasers were advised that the front yard and/or veranda of the lot were providing amenity area. 3. CONCURRENCE — Not Applicable 4. CONCLUSION 4.1 The purpose of this report is to provide background information on the noise issue identified by the residents through the petition. Based on the conditions of approval provided, staff recommends no further action be taken.
