2.0 BACKGROUND
2.1 on July 25► 1988, Council passed the following resolution:
"THAT the problems associated with drainage in the rear
of lots on Phair Avenue and Lyndale Crescent be referred
to staff for review and a report to the General Purpose
and Administration Committee."
3.0 REVIEW AND COMMENT
3.1 In the spring of 1988, flooding occured on the property of Mr. Kortekaas,
a resident of Prestonvale Road. His lot backs onto the new subdivision
lots on Lyndale Crescent.
3.2 Mr. Kortekaas, his southerly neighbour, Mr. Walter, and some residents
of Phair Avenue were concerned that the lot grading of the new properties
had caused this flooding. In addition, since the new lots are higher
than the existing properties there was some concern that additional
surface runoff water would flow from the new yards onto the existing
yards.
3.3 Mr. Walter explained that he had constructed a rough ditch some thirty
years earlier that served to intercept runoff water from the east.
The ditch ran from Lot 80 to Lot 30 with an exit at Lot 192 to
Prestonvale Road.
3.4 upon investigation, it was discovered that this ditch had been
inadvertently backfilled and that the portions of the ditch were
on subdivision lands. The ditch was immediately re-opened to alleviate
the problem.
3.5 A rear lot catchbasin at Lot 83/84 was also not operational, but, is
now functioning. The catchbasin will serve to intercept additional runoff
water from the easterly lots on Phair Avenue.

REPORT NO.: WD-45-89 ----------------------------------------
----------------------------------------
3.6 Due to the construction of a continuous stone retaining wall along the
rear of the lots On LYndale crescent in November, 1988, final grading
and restoration of the area could not be completed. This restoration
is to be done in conjunction with the sodding of the lots on Lyndale
Crescent expected to be completed by June of this year.
ng on the lots on Lyndale Crescent will incorporate an
3®7 Final grading
additional swale (ditch) along the top of the retaining wall, exiting
into catchbasins at Lots 83/84, Lots 77/78 and Lots 34/35. This will
ensure that no water from the subdivision can enter onto existing
properties.
4.0 CONCLUSION AND RECOMMENDATION
4.1 At present, it appears that the overall drainage system of the lands
in the area of Phair Avenue, Lyndale Crescent and prestonvale Road is
functional and no further flooding complaints have been received.
4.2 It is, therefore, recommended that this report be received for
information. The Public Works Staff monitor the final grading,
restoration and sodding of the entire area to ensure that the final
product will not adversely affect existing properties in any way.
Respectfully submitted, Recommended for presentation
to the Committee,
