In addition the following shall apply to development within Kelly Ranch: New development and significant redevelopment of private and publicly-owned properties, must incorporate design elements and/or Best Management Practices (BMPs) which will effectively prevent runoff contamination, and minimize runoff volume from the site in the developed condition. to the greatest extent feasible. At a minimum, the following specific requirements shall be applied to development of type and/or intensity listed below: Residential Development Development plans for, or which include residential housing development with greater than 10 housing units shall include a drainage and polluted runoff control plan prepared by a licensed engineer, designed to infiltrate, filter or treat the volume of runoff produced from each and every storm event up to and including the 85th percentile 24-Hour runoff event, prior to conveying runoff in excess of this standard to the storm water conveyance system. The plan shall be reviewed and approved by the consulting soils engineer or engineering geologist to ensure the plan is in conformance with their recommendations. The plan shall be designed in consideration of the following criteria, and approved prior to issuance of a coastal development permit: i. Maximize the percentage of permeable surfaces and green space to allow more percolation of runoff into the ground and /or design site with the capacity to convey or store peak runoff from a storm and release it at a slow rate so as to minimize the peak discharge into storm drains or receiving water bodies; ii. Use porous materials for or near walkways and driveways where feasible; . . . 111. Incorporate design elements which will serve to reduce directly connected impervious area where feasible. Options include the use of alternative design features such as concrete grid driveways, and/or pavers for walkways. iv. Runoff f?om driveways, streets and other impervious surfaces shall be collected and directed through a system of vegetated and/or gravel filter strips or other 4 media devices, where feasible. Selected filter elements shall be designed to 1) trap sediment, particulates and other solids and 2) remove or mitigate contaminates through infiltration and/or biological uptake. The drainage system shall also be designed to convey and discharge runoff from the building site in a non-erosive manner. V. Selected BMPs shall be engineered and constructed in accordance with the design specifications and guidance contained in the California Stormwater Best Management Practices Handbook (Municipal). vi. The plan must include provisions for regular inspection and maintenance of structural BMPs, for the life of the project. Parking Lots Development plans for, or which include parking lots greater than 5,000 sq. ft. in size and/or with 25 or more parking spaces, susceptible to stormwater, shall incorporate BMPs effective at removing or mitigating potential pollutants of concern such as oil, grease, hydrocarbons, heavy metals, and particulates from stormwater leaving the developed site, prior to such runoff entering the stormwater conveyance system, or any receiving water body. Options to meet this requirement include the use of vegetative filter strips or other media filter devices, clarifiers, grassy swales or berms, vacuum devices or a combination thereof. Selected BMPs shall be designed to collectively infiltrate, filter or treat the volume of runoff produced by each and every storm event up to and including the 85th percentile 24-Hour runoff event. BMPs shall be engineered and constructed in accordance with the guidance and specifications provided in the California Stormwater Best Management Handbooks Handbooks (Commercial and Industrial). All Development A public education program shall be designed to raise the level of awareness of water quality issues around the lagoon including such elements as catch basin stenciling and public awareness signs. A landscape management plan shall be created that includes herbicide/pesticide management. Such measures shall be incorporated into project design through a water quality/urban runoff control plan and monitoring program to ensure the discharge from all proposed outlets is consistent with local and regional standards. Such measures shall be required as a condition of coastal development permit approval at the subdivision stage -5- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 SECTION VII: That Section 21.203.040 of the Carlsbad Municipal Code is amended by the addition of Subsection 2 1.203.040 (G) to read as follows: G. Within the Kelly Ranch. scenic public views from Interstate 5, Cannon Road and Agua Hedionda Lagoon shall be preserved, as feasible, through the following measures: 1. Landscaping and Setbacks: Use of trees or fire retardant vegetation with substantial height as a landscape screen and/or setbacks from the ridgelines and open space areas; 2. Building Colors: Exterior wall and roof colors shall be of low intensity earth or vegetative tones. Stucco with accent materials such as tile, natural stone, or other compatible natural building materials shall be preferred. Roof colors shall be low intensity colors which blend with the environmental setting of the project; 3. Residential Building Height: Maximum height limits and variation in roof heights shall be utilized, as necessary, to minimize visibility of structures from scenic public roadways, public vista points and public trails. SECTION VIII: That Section 21.203.040 of the Carlsbad Municipal Code is amended by the addition of Subsection 2 1.203.040 (H) to read as follows: H. Within the Kelly Ranch, landscaping shall be utilized as a visual buffer and be compatible with the surrounding native vegetation and preserved open space by incorporation of the following measures: 1. 2. 3. 4. All residential development shall be required to identify and implement a landscaping plan that provides for installation of plant species that are native or non-invasive and drought tolerant to the maximum extent feasible. Ch-namental (non-invasive) vegetation shall be permitted in the interior of residential subdivisions only; Approved landscaping shall be installed immediately upon completion of construction and maintained by the property owners in good growing condition for the life of the development; Landscape screening of structures, including specimen trees and fire retardant vegetation of substantial height, shall be required to screen and soften the view of structures from I-5, Cannon Road, Agua Hedionda Lagoon, public trails and public vista points; The landscape treatment shall cause the development to blend in with the natural setting and present a visually cohesive appearance as viewed from Agua Hedionda Lagoon, Cannon Road and Interstate 5 -6- 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 EFFECTIVE DATE: This ordinance shall be effective thirty days after its adoption, and the City Clerk shall certify to the adoption of this ordinance and cause it to be published at least once in a newspaper of general circulation within fifteen days after its adoption.
