Sepulveda Dam Basin Master Plan - Los Angeles District - U.S. Army

Sepulveda Dam BasinMaster Plan and Environmental Assessmentand off-leash dog park, to opportunities to simply “commune with nature.” The diversity ofexperiences makes the Basin a very significant resource for residents of its market area and theregion.Projected visitation at Sepulveda Dam Basin through 2020 is estimated to remain stable at 2009levels in the most conservative projection, or grow at a rate equal to or exceeding the projectedpopulation increase of approximately 7%. This growth in visitation suggests additional demandsfor active athletic playing fields and lower impact amenities such as trails and picnic areas, inresponse to desires for more “green breathing space” opportunities. Recreation managers haveplans to address demands for additional playing fields, through the expansion of the BalboaSports Complex, and desired expansion at Hjelte Sports Center. Demand for such amenities isconstant City-wide and no single facility will be able to fully meet it.Basin “carrying capacity,” which includes both an environmental dimension, “how much use canthe resource support without being compromised?”, and a social dimension “how much use canoccur before the quality of visitor experience is diminished?”, presently appears to be in balance.Since it is estimated that visitation will continue to increase, future land use development plansand studies will be required to account for population growth, balance recreational diversity, andaccommodate new demands within a developed footprint in a manner that is environmentallyand economically sustainable.4.12 Land and Resource ConstraintsThis section concludes with an assessment of the physical and adjacent use conditions andfactors that will influence any potential future development of recreation amenities.Project OperationsThe primary constraint on land uses within the Basin is the periodic inundation of portions of theBasin for downstream flood risk management. Areas within the Basin have been identifiedaccording to topographic analysis reflecting the level of flood inundation and activities andstructures that may occur within each area of the Basin. Table 4.3 provides the acceptable uses ofeach inundation category, including appropriate structure constraints and appropriate recreationalor other uses.Table 4.3 Minimum Criteria for Basin Land UseEvaluationFrequencyUp to 10-yrfloodDevelopmentConstraintsSubject to prolongedinundation,sedimentation, and waveerosionAcceptable Land UsesStructures are not recommended.
