within the non-damaging flow range. However, by storing inflows, Pueblo Dam. did reduce the amount of flow reaching downstream azeas. The incremental damages preventeci by restriction of these flows was not evaluated. St Chazles Reservoir: This project is loca.ted south of Pueblo, but is not a.ctually on the St Chazles River. Therefore this facility did not prevent fload damages during this ~.vent. La Junta Local Flood Protection Levee: Prior to being overtopped and eventually being breached, the local levee prevented damages to 421 homes, 20 businesses, 1 public structure, and 57 barns, detached garages, and sheds. The residential structures and their contents have an estimated value of $4,979,000. The commercial structures and their contents have an estimated value of $676,000. The public structure and its contents have an estimated value of $33,000. The outbuilding structures and their contents have an estimated value of $622,001). This is based on an approximate delineation of the flood plain for an 8-yeaz flood event for a tatal value of $6.31 Million worth of property. The evaluation was made as part of the econora~ic justification analysis for repair of the levee under the Public Law-84-99 program. Las Animas Local Flood Protection Levee: The levee experienced erosion of at one location, but provided protection during the entire 10-year to 25-year flood event. The levee is designed to contain the 200-yeaz flood event. The levee protects 1,093 homes, 123 businesses, 63 public structures, 27 apartments and 262 sheds, barns, and detached garages. ']rhe residential structures and their contents have an estimated value of $39,080,000. The commerc~al structures and their contents have an estimated value of $16,Q36,000. The public structures and their contents have an estimated value of $37,062,000. The apartment structures and their contents have an estimated value of $3,254,000. The oiFtbuildings and their contents have an estimated value of $1,072,000. These values are based on an approximate delineation of the 200-year flood plain for a total value of $96,745,000. During this 10-year to 25-yeaz flood event, the damages prevented totaled approxirnately $7 Million. The evaluation was made as part of the economic justification analysis for repair of the levee toe under Public Law-84-99. Trinidad Reservoir: The project is located upstream of Trinidad and therefore the large Purgatoire River watershed downstream drains uncontrolled into Las Animas. The small inflow captured at Trinidad Reservoir did not appreciably prevent any flood damages during this flood event. John Martin Dam: The project is estimated ta have prevented $49.9 Million worth of damage at an estimated peak inflow of 30,000 c.f.s. on the Arkansas River. Fort Lyons Levee: The Fort Lyons Levee prevented damage to the Fort Lyons Veterans Hospital. Chapter 4- Flood Damages Prevented and Sustained Post Flood Assessment Report ~~ 32 Draft Revised 09/09/99
