Findings of Fact: Watershed Protection Overlay District 1. Whatcom County Comprehensive Plan Goal 2S6 is to: "Designate all areas within Bellingham's Urban Growth Area that are also located within the Lake Whatcom Watershed as a Resource Protection /Urban Growth Area." 2. A number of permitted and conditional uses allowed in the zoning districts within the Lake Whatcom Watershed could impact water quality if not properly designed and operated. 3. Standards for roads, parking areas, building setbacks, lot coverage and open space which apply to other areas of the county could result in impervious surfaces which exceed standards recommended for sensitive watersheds. 4. Additional standards and review for certain types of development in the Lake Whatcom watershed is necessary to reduce water quality impacts from new development. 5. The development standards proposed in the Water Resource Protection Overlay District, attached as Exhibit A, are likely to protect water quality by reducing potential sources of contamination and impervious surfaces associated with new development in the watershed. Clearing Code Revisions 1. Land clearing activities can significantly affect water quality, basin hydrology, stream channel morphology and habitat quality /aquatic ecology by introducing erosion and sedimentation from construction sites to receiving water bodies. 2. Erosion and sedimentation are of concern for a number of reasons including their impacts on beneficial uses such as fisheries and drinking water. 3. One of the mechanisms by which drinking water supplies can be affected is through the increased transport of nutrients such as phosphorus associated with the sediment. 4. Phosphorus contributes to lake productivity, and through decomposition of organic materials, added phosphorus contributes to low dissolved oxygen concentrations in certain areas /times. 5. Ecology has proposed listing Lake Whatcom as an "impaired water body" on the 303(d) list, under the Clean Water Act due to low dissolved oxygen concentrations. \ \PDS- 1 \V0L1 \USERS \PDS \SHARED\2 Planning Division \REZONE\ZONING.98\adopting ordinances \adopting ordinance61- 98.doc 6. Results of such a listing are uncertain but may significantly affect future development in the watershed. 7. Increased lake productivity can also lead to increased water treatment costs and public health concerns. 8. The increased thresholds for review and inspection of erosion controls associated with clearing activities, proposed in Exhibit C, is likely to result in decreased erosion, sedimentation and phosphorus in the stormwater which drains to Lake Whatcom.

Each existing lot shall be allowed only one driveway or curb cut: adjacent lots are encouraged to share access points. In new developments, lots or leased sites shall be oriented toward internal driveways, parking areas, or roads, with limited access to arterial or collector roads. Access points to arterials and collectors should not be closer than 400 feet apart except where physical constraints make closer access points more appropriate 20.71.700 Roads, curbs, putters and sidewalks. The intent of this section is to reduce impervious surfaces and stormwater runoff. Innovative street sections, which do not compromise the public safety, shall be encouraged in the watershed. Narrow streets and reduced sidewalk standards that satisfy pedestrian and vehicular circulation requirements may be implemented with the approval of the Whatcom County Public Works Department. Unless specifically required, roads shall not be wider than the minimum applicable standard. A rural road standard may be approved by the Whatcom County Public Works Department for urban density residential areas where the developer provides adequate off - street parking and pedestrian walkways. Use of shared parking facilities and pervious pedestrian walkways is encouraged. (2) Chapter 20.80 of the Whatcom County Code is hereby amended as follows: 20.80.521 Drainage. All parking and loading areas shall provide for proper drainage of surface water to prevent the drainage of such water onto adjacent properties or walkways.

(b a) Water Resource Special Management Area Designation. Whatcom County shall establish the following geographic areas as water resource special management areas: (+ ).Lake Whatcom Watershed; k4 2) Drayton Harbor Watershed.
