HomeMy WebLinkAboutStormwater - D52 - EROSION CONTROL FOR CONSTRUCTION ON INDIVIDUAL RESIDENTIAL LOTS (PDF) - 1/9/2012Erosion Control for Construction on Individual Residential Lots Scope The following requirements apply to all single-family residential projects, including; · New single-family residential construction · New construction (i.e. additions, etc.) on existing single –family sites · Idle single family lots both permitted and non-permitted (lots owned by the builder or land developer not yet under construction). · Grading, excavating and stockpiling of earth and landscape materials (not specifically limited to new construction) which results in the transport of any of these materials off site by any means including, but not limited to, wind or water erosion and vehicular tracking. Enforcement The requirements herein are enforced through the requirements of the Fort Collins Stormwater Criteria Manual, and applicable ordinance. Failure to comply may result in the refusal of inspections, refusal of Certificates of Occupancy, and the suspension, revocation, or cancellation of Building Permits. Excavations for basements When lots are ready for basement excavations and / or additional grading, the BMPs that are protecting the lot shall not be compromised during the operation. BMPs may be temporarily removed to allow for access and promptly reinstalled at the end of the basement excavation and/ or grading operations, or at the end of the day- whichever is sooner. At no time shall the lot specific BMPs be removed over night or during precipitation events. Basement excavations / grading shall not be performed on a lot(s) if excessive tracking of sediment onto streets will occur. This is often the case after recent precipitation events, which cause the lot to be “muddy.” Material from basement excavations shall be contained and protected from sediment transport by surface roughening, watering and perimeter silt fence or other approved BMPs. The excavated material shall comply with all stock pile criteria outlined in Fort Collins Stormwater Criteria Manual, specifically, No stockpile shall exceed ten (10) feet in height, and any stockpile remaining after 30 days shall be seeded and mulched. If the excavated material is to be moved, and sediment is tracked onto streets, all sediment shall be removed immediately. The streets shall be scraped and swept periodically throughout the day and at no time shall the material be allowed to remain on the street overnight. All BMPs shall be reinstalled at the end of each day. Inlet protection Following the direction of flow off the site, the nearest inlet is required to have inlet protection, it shall be installed & maintained per the Fort Collins Stormwater Criteria Manual requirements at all times. Street/Sidewalk Sweeping City ordinance prohibits the tracking, dropping or depositing of soils or any other material onto the city streets by or from any vehicle. Any inadvertent deposited material shall be cleaned immediately by the contractor. Street sweeping shall be performed on a regular basis. The frequency of sweeping will depend on construction activity, the amount of deliveries, the overall effectiveness / maintenance of the BMPs, as well as “good housekeeping” practices. City of Fort Collins may request additional sweeping if material is tracked onto streets. The street sweeping shall be completed within 24 hours of the request. Maintenance of lot BMPs Maintenance shall be performed on all lot BMPS on a routine basis and after all precipitation events that cause surface erosion, reference the Fort Collins Stormwater Criteria Manual for proper specifications, installation, and maintenance requirements. *Lots That are in sensitive areas, or conditions are such that the lot(s) cannot be permanently stabilized for an extended period of time, may require the entire lot to be covered with erosion control blankets. This will be determined on an individual lot basis. ** When all required BMPs are installed and an initial inspection is needed please call the erosion control inspector at (970) 224-6015, please notify at least 24 hours prior to any construction on this site. If any questions arise about the erosion control needs of a site, this number should be used.
