Woods and Grove Apartments (KAMAR). :Ourevs.luation of this material and field ,insp'eetipnof the·axea. has revealed "that this proje(;t has the potenti"al to ,cause significant advers'e impacts on fish and w-ildlife res,?uxces -w.hich have riot" been adequately ,ci1scussed. Dur::1.ng heavy rains, silt could be washed :f:rOm tlre development ,site Slld into the lagoon. The statement on page 81 which refers to this ,subject states only that "Development should diminish erosion and reduce the seq,imentation, rate to Buena Vista Lagoon;1l ""This statement 'is erroneous since the -present understory of vegetation prevents all but minimal' siltation of the lagoon. We reeommend revising t,he drat't, report to disCllS'S this type of concern and various ways in which such erosion can be controlled. Specifically, the s'*ltation prob--lero: should be solved before it has a chance, to occur. Holding basil1s or sedi.1'llentation ponds should be used to remove. silt from :the drain ... age uater cooting :f'rom the development before it enters Buena Vista La.gQ,on. Also, construction ,should be commellced. after , the rainy sesson. and a:n graded tJlopes should be planted to soil binding veget'ation (with wildlife values, if possible). , . Many of these same aspects apply to the property which lies adjacent to Marron Road. The drat't report states on page 44 "Most of the runoff water is channeled into the Buena. Vista. Creek which lies to the base of Hosp Grove. If The development of this area would increase the silt runoff into Buena Vista ere:ek 'theEce-into' Buena: Vista Lagoon unless effect~ve· sed1:tnentat.ion and . erosion control measures were taken.

In a -. letter ·to the ·City of Carlsbad Planning De.partment·.(received March 16 I . 1973) the California Department of Fish and Game considered the state- ment; "Development should diminish e,ro,sion and reduce the sedimenta- tion rate to Buena Vista Lagoon II I as erro~eo~s since the present under- story"'of vegetation prevents all but minimal siltation to the lagoon, . The statement was based on the tact that erosion to the area will he less after final completion of ·the ,Hos.p, Grove developl1!-,ent then it is in its present state. The erosion of the site area will be lessened by runoff water$ being . channeled along paved streets and into a subsurface storm drain system. The increase in landscaping around the project site will also help to limit the erosion of the area. Erosion will still continue in the areas of Hosp Grove to be left in its natural state I but hot to the extent as in the past. Less runoff water will be available to run down the sand-stone gullies found on the project site. The Department of Fish and Game is correct in their as'sumption that the project site in its present state of deVelopment probably hqs had an ._._-_ .... ---_......:..._---_ ...... _-.. -. -........... ~ ... _ ....... _ ....... . t • ~ .J • "'. 1 ~ ............

This increase is due to the fact that large areas of the ,eastern section of Hosp Grove have been graded and are exposed to storm runoff waters. The developer (Kamar Construction Company) has taken steps ,to reduce both the erosion andsHtation by planting grasses along the cut slopes and by placing two $J1.tation catch basins at the base of the graded cut slopes along Marron Road. Should the Carlsbad City Engineering Department feel these procedures are inadequate after examing the area, the developer (Kamar) has , . ~ -" suggested a third temporary siltation basin at the base of the proposed Monroe Street eX,tension. This basin would catch runoff water' from the western portion of the development until completion of the proJect. Storm drain discharge from the eastern portion oJ the' project will connect with the major storm drain located aloflg El Camino Real. The system th~n empties into Buena Vista Creek approximately one mile above the lagoon headwaters. Runoff waters from the western portion of the -. development will flow down to Marron Road and connect to the drainage system located in the Plaza Camino Real Shopping Center. The drainage .. wate~ is then channeled in an open ditch to Buena Vista Creek above the ,lagoon. Should it be found that siltation will become a major problem to the lagoon due to the increased development in the area, it would be best to eliminate the silt by some manner along the flat area below the project site where runoff water velocities are at a minimum, and the silt easiest to remove. , • t '(',.. ,. .~::...:---~.::-.".,.-.-.. '. -_.-.-.. -----" --_. . . ~ \ • .'f In conclusion, the completed Hosp Grove deveiopment with its paved areas and streets, landscaping, and storm drain syste~ should diminish the erosion of the project area and reduce the siltation to the head- waters of the Buena Vista Lagoon. . .~ ..
