Irrigated bio-retention <br />swales and areas shall be designed as needed to the satisfaction of the City <br />Engineer to optimize the amount of the storm water running off the paved <br />surface that enters the bio-retention swale at its most upstream end. This <br />plan shall be subject to the review and approval of the City Engineer prior to <br />the issuance of the first grading permit for the development covered by this <br />approval. <br /> <br />b.

In areas that provide detention of water, plants that <br />are tolerant of saturated soil conditions and prolonged exposure to <br />water shall be specified. Soil shall be amended as required. <br />· Plant materials selected shall be appropriate to site specific <br />characteristics such as soil type, topography, climate, amount and <br />timing of sunlight, prevailing winds, rainfall, air movement, patterns of <br />land use, ecological consistency and plant interactions to ensure <br />successful establishment. <br />· Landscaping shall also comply with City of Pleasanton ordinances and <br />policies regarding water conservation. <br /> <br />The CC&R's covering Lots 2 and 4 through 27 shall include the above <br />statements in their wording. <br /> <br />d.
