Subject:86 Glenview Avenue: Application for consent under Chapter 276, Article I of the former City of Toronto Municipal Code to allow the construction of a deck within the Chatsworth Ravine at the rear of the new house which is located outside the Ravine. (Ward 22 - North Toronto)

Purpose:

To obtain City Council's consent to Application No. 098053 respecting the construction of a deck at the rear of the new house currently under construction at 86 Glenview Avenue.

Source of Funds:

Not applicable.

Recommendations:

1.That City Council consent to Application No. 098053 respecting 86 Glenview Avenue to permit the construction of a deck located within the Chatsworth Ravine, on the condition that the owner enter into a Ravine Control Agreement requiring:

(a)that the owner shall provide and maintain the landscaping and ravine improvements substantially in accordance with Plan No. A-1, A-2, A-4, A-5, and A-6, date stamped as received on November 30, 1998, prepared by Makow Associates Architect Inc., as on file with the Commissioner of Urban Planning and Development Services.

2.That the owner submit sediment and erosion control details to the Toronto and Region Conservation Authority for review and approval prior to the issuance of a building permit for the deck.

3.That the City Solicitor be authorized to prepare the necessary agreement.

4.That the owner be advised to remove all landfill and construction debris from the site, to not place any fill within the ravine and to contact the Forestry Section, Parks and Recreation Division, Economic Development, Culture and Tourism Services, at 392-1900, upon the completion of all work as indicated on the approved plans.

Comments:

1.PROJECT: To construct a deck located within the Chatsworth Ravine at the rear of the new house which is currently under construction.

2.LOCATION: On the north side of Glenview Avenue to the west of Duplex Avenue and immediately to the south of the Chatsworth Ravine Park.

3.SITE: The property is rectangular and very deep, sloping from the rear of the house down into the Chatsworth Ravine. The current owner of the property is in the process of constructing a replacement house within the table land portion of the site, however, most of the proposed deck will be located within the Chatsworth Ravine.

4.COMMENTS FROM CIVIC OFFICIALS (see Appendix A):

(a)The Commissioner of Urban Planning and Development Services has indicated that the proposed deck complies with the requirements of the Zoning By-law. The applicant previously obtained a gross floor area variance for excess density related to space within the third floor of the house. This decision of the Committee of Adjustment was granted October 16, 1998 and is now final and binding.

(b)The Commissioner of Works and Emergency Services indicated his satisfaction with the proposal subject to conditions related to drainage.

(c)The Commissioner of Economic Development, Culture and Tourism Services stated that the current proposal satisfactorily addresses their concerns regarding the preservation of the natural vegetation within the ravine.

5.PLANNING CONSIDERATIONS:

Conclusions:

The applicant has proposed the upgrading of indigenous plant material within the ravine portion of the site and has modified the design of the deck to respond to the physical characteristics of the ravine behind the new house which is currently under construction. In this instance I believe that the current proposal for the construction of a deck at the rear of the new house is both reasonable and within the intent of Chapter 276, Ravines, of the former City of Toronto's Municipal Code. Therefore, I recommend that City Council give consent to the proposed development, subject to the owner entering into a Ravine Control Agreement.

2.Works and Emergency Services (December 14, 1998)

Comments:

The project on the site located on the north side of Glenview Avenue, west of Duplex Avenue was the subject of the Departmental report dated August 13, 1998.

The plans have been revised to, among other things, show a retaining wall along the north perimeter of the interlocking stone patio, the construction of the patio at basement level and the construction of the hoarding. These revisions do not affect the comments and recommendations contained in the previous report.

(August 13, 1998)

Recommendations:

1. That the owner be advised:

(a)Of the need to receive the approval of he Commissioner of Works and Emergency Services for any work to be carried out within the street allowance; and

(b)That the storm water runoff originating from the site should be disposed of through infiltration into the ground and that storm connections to the sewer system will only be permitted subject to the review and approval by the Commissioner of Works and Emergency Services of an engineering report detailing that site or soil conditions are unsuitable, the soil is contaminated or that processes associated with the development on the site may contaminate the storm runoff.

Comments:

Location

North side of Glenview Avenue, west of Duplex Avenue.

Proposal

To construct a single-family dwelling with a deck and patio within the designated ravine lands.

Ravine Control Area

The northerly portion of the site, containing the proposed wood deck and paving stones, will be located in the lands designated as ravine and is subject to Municipal Code Chapter 276, Article I (Chatsworth Ravine).

Parking

The provision of 1 parking space to be provided in an integral garage, satisfies the estimated parking demand for 1 parking space and, as far as can be ascertained, the Zoning By-law requirement for a like number.

Refuse Collection

The City will continue to provide this project with regular curbside refuse collection in accordance with the provisions of the Municipal Code, Chapter 309, Solid Waste. This will require the provision of a rodent proof storage area on private property to separately store recyclable and non-recyclable material generated between collections.

Storm Water Management

It is the policy of City Council to require the infiltration of storm water run-off into the ground for all new buildings, whenever possible. Therefore, storm connections to the City sewer system will only be permitted if it can be demonstrated that infiltrating storm water into the ground is not feasible. Further information regarding storm drainage can be obtained by contacting the Engineering Branch (telephone no. 392-6787).

Work within the Road Allowance

Approval for any work to be carried out within the street allowance must be received from this Department.

3.Economic Development, Culture and Tourism (Parks and Recreation) (December 30, 1998)

This will acknowledge your Short Stream Circulation Form of December 2, 1998 which contains a Site Plan A-1, Ground Plan A-2, Elevation Plans A-4 to A-6. The construction and elevation details of the rear upper deck, patio and stairs meets our approval. The hoarding and siltation fence are clearly marked on the appropriate plans as requested by our department. Please note, all land fill and construction debris must be removed off site once all construction is completed and in no way shall any of the land fill be placed in the designated ravine.

If you should have any questions or comments please do not hesitate to contact Mr. Bruce Gordon at 392-1900.

4.The Toronto and Region Conservation Authority (November 10, 1998)

Further to our letter dated August 10,1998 (copy enclosed), we advise that our comments remain unchanged.

We trust this is satisfactory. However, should you have any questions please do not hesitate to contact the undersigned or Gaspare Ritacca at extension 324.

(August 10, 1998)

Authority staff has reviewed the above applications and we offer the following comments.

The subject property is located adjacent to a valley corridor associated with a tributary of the Don River. The Authority's Valley and Stream Corridor Management Program (VSCMP) defines the valley corridor by a line established 10 metres inland from the stable top of bank. New development is not permitted within this valley corridor area. However, in accordance with Section 4.2 of VSCMP, new development may be located closer than 10 metres from the top of bank provided that it is consistent with the existing surrounding development along the corridor reach.

Although the proposed development is partially located within the City's Ravine By-law boundary (Chatsworth Ravine), Authority staff has visited the subject property and we are satisfied that the proposed works are sufficiently setback from the top of bank and consistent with the existing surrounding development. However, we do require details in regard to proposed methods for controlling/minimizing sedimentation and erosion during construction. For your reference, we have enclosed a sediment/erosion control fence detail.

Based upon the above, we would have no objections to the approval of this application subject to the following condition:

1.The applicant submit sediment and erosion control details to this Authority for review and approval.

We trust this is satisfactory. However, should you have any questions please do not hesitate to contact the undersigned or Gaspare Ritacca at extension 324.
