22.0 Schedule "C" 

Site Alterations shall be performed in accordance with these Guidelines.

1. Site Dewatering: Water pumped from the site shall be treated by temporary sedimentation basins, grit chambers, sand filters, or other appropriate controls and treatment methods. If the water is demonstrated to have no particles greater than 40 microns in size, then dewatering operations may be conducted provided the water is not permitted to discharge directly into sewers, receiving any body of water. Proof of a valid Permit to Take Water (PTTW) issued by the Ministry shall be provided to the General Manager for sites involving the pumping of more than 50,000 litres of groundwater per day.

2. Drain Inlet Protection: All rear lot storm drain inlets or any other inlets as the General Manager considers necessary, shall be protected with filter fabric, or equivalent barriers meeting design criteria, standards and specifications accepted by the General Manager.

3. Site Erosion Control: The following criteria apply to land disturbing activities that result in runoff leaving the site:

(a) Run-off from adjacent areas passing through the site shall be diverted around disturbed areas, if practical. Otherwise the channel shall be protected by sediment control fences being placed along the channel edges to reduce sediment reaching the channel;

(b) All activities on the site shall be conducted in a logical sequence to minimize the area of bare soil exposed at any one time;

(c) Any fill storage piles containing more than one hundred cubic metres of material shall not be located with in a down slope drainage length of less than ten (1 0) metres to a roadway or drainage channel. If remaining for more than thirty (30) days, said soil or dirt storage piles shall be stabilized by mulching, vegetative cover, tarps or other means. Erosion from fill storage piles which will be inexistence for less than thirty (30) days shall be controlled by filter fence barriers around the pile;

(d) Runoff from the entire disturbed area on the site shall be controlled as follows:

(i) All disturbed ground left inactive shall be stabilized by seeding, sodding, mulching, covering, or equivalent control measures. The period of time of inactivity shall be at the discretion of the General Manager but shall not exceed 30 days or such longer periods as deemed advisable at the discretion of the Commissioner.

(ii) Notwithstanding paragraph 3(d)(i), a Site Alteration Pennit holder or applicant for a Site Alteration Permit who has applied for but not yet received a building permit or any other necessary permit may be granted an extension to the permitted period of inactivity at the discretion of the General Manager, provided that said applicant or permit holder provides satisfactory proof that he/she has made best efforts to obtain the said building or other necessary permit.

(iii) For sites with less than four (4) hectares disturbed at one time and with slopes less than twelve (12) percent grade, sediment control fences or equivalent measures shall be placed along all downslo'pe sides of the site.

(iv) For sites having drainage area of more than four (4) hectares disturbed at one time or with slopes greater than twelve (12) percent grade, one or more sediment basins should be constructed. The basins shall be designed to trap sediment particles greater than 40 microns in size and be constructed in accordance with any applicable City of Waterloo design standards and proper engineering principles.

(v) For sites located adjacent to existing residential areas, a sediment control fence may be required around the entire perimeter of the site;

(vi) A three (3) metre wide buffer strip or sediment control fence shall be required along the perimeter ofthe downslope sides ofthe site;

(vii) For sites with extensive fill requirements the General Manager may waive the requirements for stabilization of disturbed land after thirty (30) days of inactivity provided that the sediment control measures have been implemented to the satisfaction of the General Manager.

4. Reverse Driveways: New driveways must be designed to avoid the use of reverse driveways (sloping downwards towards the house or building). For reconstruction work and Site Alterations involving modifications to reverse driveways that existed prior to the enactment of this bylaw the owner must ensure that flood protection is provided. Reverse driveway drainage facilities must not be connected by gravity to the storm sewer system unless it can be demonstrated in a stormwater management report signed and sealed by an Engineer that surcharging by the sewer system during a 1: 100 year storm will not cause flooding to the property.

Subject to the provisions of any other bylaw, the General Manager, in consultation with the City Forester, may provide relief from the requirements of these tree protection policies or require tree protection measures above and beyond the tree protection measures prescribed in this policy having regard to the variety and location of the tree and any circumstances surrounding the Site Alteration that may pose a particular hazard to the tree.

3. Tree Protection Zones

A Tree Protection Zone or TPZ for any tree shall be determined as follows:

Trunk DiameterMinimum protection distances required

<10cm

1.8m
11 - 40cm 2.4m
41 - 50cm 3.0m
