Our initial study chetklist described the potential water quality problems inherent in this project, although there may b6 some disagreement as to the degree of pollution anticipated and the relativesignificance Of i4's effects. (Co�,nczdentally, T just attended a lecture given by Dr. Stephen P. Hayes, Ph,D., of the State Vater Resources Control Board, Dr, Hayes described the "assimilative capacity" Of a stream as "its ability to absorb pollutants and puri fy L` i rocF,�se g itself through time and distance throw It a cpm chemical and biologic'al ple:x of, ph;� sical ca acit p S . lie stated the as.a milatI've � p' y permits stream Waters to receive androcess and still, support a 'variety of other uses.) � Pollutants, DishOur initial contacts 14ith Richard p'lYnt of the Department Of Fish Wid Game and Tony Lar►dis 'of the State Itegibnal Water y r p j would lie relatively minor bocause o this ro ect. t Cont of Board indicated that the efi ects of runoff, .and. because the n'unlbexs of fish sttp�soxtcdeiri this of toxin stream are not that high, ma.Ic g' 't of littiitOd importance in terms or fishery �valuo.

Y might add that this department is aware of the cumulative concerns related to additional; drainage out fabs into Big Chico Creek, and Will address the cumulative effects as new projects come up for review. Your last question asked under what authority Mfr. Risco was operating when he questioned DFC and USFIVS comments. s suspect he did this on his own initiative because he felt the project cies tieing unjustly harassed and. hindered. Probably he thought his statements would accelerate project: approval by overcoming Past objections and perhaps blocking future ones. In such an actxo.n, of course, there is always the clanger of stifling legitimate expressions of concern and public debate. MY office was not consulted in that particular action, so we were not given opportunity to comment before the fact. The first knowledge z had of ,fir. Risso's letters were the copies you sent me . The Sacramento Avenue Assesswent District formation is noti►t an accomplished fact whic, I guess we most adjust to. is appreciate Your interest and concern in this muter, and look forward to working with you in the future.

Alternate 1 (proposed project), which approved the implementation of two (2) controversial storm drains for outfall into Big Chico Creek, and also for future storm drain outfalls. My specific concern is the protection of the fish and wildlife resources of trig Chico Creek as an interested resident rind -taxpayer of Butte County. l spoke to you recently regarding this matter. Please understand that my concerns for Big Chico Creek, are consistent with the past concerns of Butte County,whereby the county it 1`969 did recommend:to the Resources. Agency that Big Chico Creek be protected under the umbrella of the California Protected "Waterway's Plan (initial element). The Re,nurces Agency in accordmice with the concerns of the county classified Big Chico Creek as a Extraordinary Fishery Tr+taterway; Class I PreMuim Waterway for :sa:'.n)on and Fos* Stgnl, ead. As 2 indicated to you, thi s `Was plot addressed in the environmental evaluation report for the proposed project.

Also on 'Wednesdays August 6 a_meet with various staff persons of the Resources Agency, Reclamation 'Board, and the DFG in Sacramento, regarding these concern'41 r .x Page No; Earl D. .son, Environmental Review Dir *r, Butte County As you may be aware., the DFG is the Truste Agency of the state's fish and, 'wildlife resources, and, has the jurisdiction by law, over the natural v resources affected, by a project. These resources are held, in trust by the DFG for ,all. the people of the State of Call fornia. On Thursday, August 71 1 also contacted, the offices of the U.S. Fish and Wildlife Service (USFWS) and discussed their concerns for the proposed Project. Also as yoia may be aware, under the provisions of the U.S. Fish and Wildlife Coordination Act the USFWS is re aired to comment on the proposed. Project. These provisions also re wire that losses and,damage to the fish and. wild ife resources be prevented: I am also aware of the June 2, 1980 letter from the USN8 to the Corps of Engineers which Is ecial7 su orted the recommendations of the local representative of tho DFG regarding the 1603 agreement issued, on Pebruary 1 4, 1980, Also on Thursday, August 7, I spoke to you regarding certain defects. in the environmental evaluation report, and, also regarding the existing g (5) applications for storm drain outfalls into Dig Chico Creek. r pointed. out to you that the environmental evaluation xeport also failed to address the cumulative effects to Stater quality, floodings And, the fish and: wildlife habitat and, resources from proposed, storm drain outfalls. you indicated. that under', pervious environmental;report the Sig Chido Creek basin could.'handle these discharges with regards to flooding however this report was not cited in the environmental evalution report,, Also in "reviewing the June 2, 1980 letter lay the USFWS,.

That letter requests that we discharge tho storm drainage into Lindo Channel. We have investigated this alternative, and have determined that it is not feasible for the following reasons: 1. The installation of the storm drain pipe down Hwy 32 _ to�Linda Channel would necessitate the. removal.-o£. approximately 40--50 mature treos. 2 The City of Chico and Bute County do not desire a storm drainage system eXtend ng through prime agricultural Land. Such systnm woulC be growth inducing and Would encotirago further development of agricultural lands. 3. The project would become u=nvmicAlly 'unfeasible. The costs Would skyrocket from approximately $3000:00 per acre for discharge to Big Chico Creek to $1.4000.00 per acre for d?,schargc to Lindo Channel,. U.S. Fish and Wildlife has 'also expressed concerns about eater quality and flooding downstream in Big Chaco Creek, Lnol.osed please find a letter from tha California Regional Water Quality Control, Board that stjtes"Water quallty certification Will: not be regaia.;edll birec'ting discharge to Lindo Channel. will: hot mitigate flood ,ng problems; At present, 1.1"Mit.ed ".00dittg occurs dOWnstream Rom, the ',junction of Sig Chico Creek end Lindh t { .r� U.S. Army Colesof Engineers 650 Capitol Mall Sacramento, CA 95814 June 3, 1:980 Re COE permit 7072 Page 2 Chanriel. The flooding occurs because the creek is choked with trees and brush in .its downstream xcache he Big Chico Creek watershed covers approximately 72.4 square miles and the main channel length is 31.6 miles according to data provided by the U.S. Geological. Survey in their, "Water -Resources Investigation 77-21.11. Time of concentration for peak discharge of the watershed is somewhere between 6 to 8 hours after, initial, rainfall begits. Tomo of concentration for our proposed system is approximately 40minutes. Thus, the peak from our proposed system will have passed the critical channel area well in advance of the watershed peak. A portion of Big Chico Creek is diverted during high flows into Lindo Channel and the Sycamore Creek drainage basin east of the City of Chico. The water entering Big Chico Creek at the diversion point is restricted to 1.500 cf.s. by a gate system. The creek between our proposed discharge point and its intersection with Undo Channel. has a capacity of approximately 3100 c.f:s. High ,banks combined with a relatively smooth stream bed allow passage of this quantity off' water.' Our anticipated peak discharge of 140 cif..s. does M )se a problem with regard to flooding. Aftex we applied for the Corps permit, we met with officials an, engineers with the State of California 0opartment of Fish and Gamo (nFG). The DFG had objections similar to those of the Fish and Wildlife Service. Working together,, we designed sediment traps and volatile Liquid traps. These designs have ;been approved by brG and they have since withdrawft their ob;ectians It would i`appear to us th.dt the 'Fish and. Wildlife Service has taken a tip 8sitig u n inconsistent with the facts; good . en,ineerih dement andcommo'n sense. Our efforts to appease this _agency have been consistently ,rebuffed, and no V/ rotponsibl.e suggestions or alternatives have been receivers. . We feel, that: the ball is now in Fish and Wildlife Services' park.

The maximum discharge ca.nacity of the project drainage system will be approximately 1.60 cfs, increasing dow.nstroam flows by ten percent. Typical drainage ass charge from project; facilities during a normal 1-year storm would be expected to be 60 * cfs (20 minute 'gime of concentration). Average daily flow rates in,Big Chico Creek during the rainy season winter months has ranged from 110 cfs to 2C 5 cfs (mean 210 efs) over the past several years (;gaging station located jMst cast of hose Avenue bridge) Currently, runoff drainage from properties lying within the Assessment District i.s not removed from the land, but either infiltrates into the soil jr ponds on the s'ur4-:ce (which is typical in the area as a consequence of impervious surfacing) Upstream of the project site is the City of Chico and Bidwell City Park. Urban drainage is presently discharged into the stream from existing developments. However, no summer drainage discharges are allowed in the creek within Bidwell Park due to downstream recreation- al water use`s. Theseuses are Upstream from this project. 3(c)`: The two outfall structures to be located 'in the Big Chico Creek channel:.will require somelimited stream bank alteration and minimal vegetation removal during construction; as well as placement of con p p ivithin the stream channel below the :Wean high water creta xa. ra material level,, a The bufall structure should be oriented in order to avoid the y f removing ainy mature trees 3(e), (j); The Cincentration of drainage discharge from the 160 acres will add approximately 1006 additional runoff to Big Chaco Creelt stream- floe at maximum discharge. Downstream from the points of dischargej. the lands adjacent to Big Chico Creek are deVCiaped to a variety of uses. Immediately below the eastoxnumost discharge point urban development exists. Downstream from the primary outfall Jocation (proposed to be 600 feet southwest of the Rose Avenue bridge), the lands are largely in tion-urban uses; except along Bidwell Avenue Which contains :,tattered resldentx al use since the Assessmr;nt bi strict lies in the southwestern port-ton of the urban area.

Furthermore, the peak from the 'Estates' would precede the peak.. of 'Big Chico Creek. Accordingly; the peak discharge of 20 c•f-s 'would occur approximately 1.7 hours before the peak discharge of 1,1770 cfs on Big Chico Creek. This result genera lly' concurs with that expected from theoretical considerations for a singular precipitation/"iood regimen, and provides a reasonable ( albeit approximate) value of concurrent peak lag for the purposes of this assessment. Observations of particular significance to the proposed Big Chico Creek Estates project and the is.sue of stotrd-drainage/ flood concurrence with Big Chico Creek are that:: 1.

In contrast, the peaks would coincide if the project Uere located more distant from the Creek, with a 1.7"hour outfall -conduit travel time; 3.
