The site was first visited on August 30, 1984. Heether conditions were good, the site was dry, with the last significant rains 6 months previous to the visit. During that time a thorough study was m3de of the bluff on both the site end the surrounding properties, and a report was submitted to the owner. A second visit was made on July 20, 1988, under similar conditions. The changes on the site during the four years between visits was noted during the second visit.

The site is set at the seaward margin of th~ F·leistocene marine­te1·race at Cayucos. The surface of the lot is flat, with a slight. senward slope. There ere no well defined drainage channels or swnles crossing the lot. The lot is about 35 feet wide. with a house set approximately 35 feet from the top of t!1e bhiff. The A house occupies most of the width of the lot. '""

The top of the bluff is a·lmost vertical, except Z\t th'"" r;•.:>uth end of the lot, where there is a more gentle slope toward a rocky spur ~f bedrock. The spur extends outward about forty feet from the general line of the bluff. The seaward end of the spur is w!der and higher than the landward end. In most locattons the bluff is toe• steep to safely climb to the beach. There· is a small coYe, er reentrant, on the north side of the spur. with a smaller headland on it£ north side, end a deeper cove or1 the north side of the smeller headland.

The average gradient b~+-~·1een the top of the bluff end. the base is about 55-60 degrees along the north hal~ of the lot, and shows a sligh~ increase ~rom that ~easured in 1984.

The geology consists of abo•Jt 12 feet ·of Franciscan greenstone and sandstone melange .materials, overlain by 1 foot of shell-bearing marine terrace deposits, 3-4 feet of grey and brown reworked dune and beach sands, and 5-6 feet of colluvium ..

The Fr&nciscan Formation greenstone occurs en the western end of the small spur· or headland on the south property line. and on both sides tt of the small reentrant on the north property Jine. The greenstone

COMMENTS MADE IN 1984' ,REPORT

Study pf air photos end discussion with the occupant 9f the residence, indi~ate that the bulk of the bluff erosion has taken place since the great storms of 1982-3, and that erosion prior to that time was not exceptionally fast C2-3 inches/year>. It appears that cignificant amounts of bedrock were removed from the base of the bluff, especially the greenstone at the north end. At the same time1 extremely high waves removed larf£e amounts of terrace material, especially on the north side of the small spur, end along the northern property line. These two areas were subjected to wave focuss;'ing and to wave reflection, both of which c\:mtributed to a very &'igh erosion rate during the large storms. Erosion has continued, as the terrace materials: are still stabilising toward a new bedroqk bluffline. Much of the present bluff retreat is due to esrlier undercutting of the top of the bluff, which remained in place under the influence of a binding ground cover of veget5tion. In several places. about three more feet of bluff top recession muy be expected from existing undercutting. It is estimated that at least 12 feet of bluff top retreat has taken place on the northern property line since the 1982-3 storms. The entire bluff has retreated about 4-5 feet, at the very least, since the 1982-3 season.

CHANGES BETWEEN 1984-1988

Tape lines were run along the same lines in both surveys, and !>how that there hss been very little recession of the top of the bluff. The ave~age 55 degree slope that existed at the north end 9f the site has been slightly steepened, and the amount of vertical or overhanging bluff top has increased. Tbis indicates that the bluff has been eroded slightly from tbe base, and has become steeper at the north end of the lot. The upper pert oi the bluff has therefore become more unstable, and a 3-4 ft. t·ecession of the top of the bluff can be expected within a decade along the north half of the lo~. The bluff has become slightly more unstable, although the large recessions predicted in 1984 have not yet taken place. It is also noted that some of the riprap along the southern edge of the ...,aJ.l on the adjacent property to ·the north that was present in 1984 had disappeared in 1988. ·

R.ECQW=raNDATIONS FQR CQA$TbL ERQIECTION

If the extreme waves of 1982-3 were guaranteed not to return, ther~ would .. be l.ittle immediate need for coastal protection. However, the bedrock cf the bluff" appears to be weak. and is eroded by very large waves. Thus the existing 25-30 feet between the house and the bluff could be removed in just a couple cf very severe storm seasons, and in this light I would recommend that some coastal defense be constructed.

I recommend that the defense be placed at the rear of the small cove, or reentrant, along the northern property line, ~? et the ~ear of the small cove just north of the small hesdlend These are the areas that suffered the worst erosion in the past, partly due tv wave reflection and focussing.

The defense should either be riprap, placed at the rear of each cov~ and placod dirsctly on bedrock, or should be a concrete block seawall. The latter should be constructed on firm bedrock, and should stand out several feet from the present irregular bluff face, and close to tpe rear of each small bay. No defense is needed on the sides or fro~t of the headland, or the region bet~een the two small coves. If a seawall is constructed, it should be constructed with cross drains, and should be backfilled with concrete. If a seawall is designed to stand at the very back cf the cove, tight against the bluff, then it should be designed with wave reflection structures to divert washup from the overlying, essily eroded, terrace materials.

If riprap is placed at the base of the bluff, there will be a ??F~inued recession of the top of the bluff over a space of decades, the' rate determined by the amount of r·e.in, spray, foot traffic etc. It ·will probably revert to a slope close to 1:1, which will in no 4IJt way jeopardize -the safety of the house, but could produce an ultimate recession of the bluff top by about 10 ft. This recession

This report is in response to questions raised in a letter from John McKenzie to Gteve Sylvester {8.l6.89i and a letter to Ted Bench from James Johnson ( 8. 14. 89). Each question wi 11 be answered und'er separate~ h~ading.

l} Specific discussion of bow the redirected water energy/flo~z from 1:he proposed,, seawall will have a mi~imal er-osion impact on the adjacent property to the north <McKenzie).

Two sections of seawall are proposed for this pr-eject. One ... ·ill border the adjacent seawall t•:i the north, and wi 11 trei;d in a generally southerly direction, terminating in a rocky spur just north of the parcel's long axis center line. The second segment will have a similar orientation, filling the rear of the embayment between the aforementioned spur and the rocky headland st the southern property line.

Waves can approach these walls only frc the south~9~t ·~~~dr&nt. Only in the cente!" of the quadrant, with waves com~·qg f:-orr• the: south ~est, would wave energy be a $ignificant impact on the noftherrr-~all segment. Waves coming from both southwest and west could impact on the southern wall segment. Allowing that ~ave reflection would be dominantly controlled by Snell's Law, dominant wave reflections would be to the west and south west, and normal to the wall. Thus direct wave reflection would not be toward tha property ori the north. However a more southerly storm would produce lesser direct wave impact, but some reflection toward the wall on the property to the north. However this reflection exists in the natural state, and the wall would not aggravate the effect.

Rip rap tends to produce a less coherent wave reflection tban a s::.10·'.:)tb rock -face. and wi 11 t.h-'!ro:for-e prod•.Jco: a greater reflect iv& en:rgy diss~p~tion than the natural :-ock face.

2) What is the historic bluff retreat:. rate (yearly averag~ over th€: e last 50-75 years}? CMcKen=ie)

Unfortunet:ely for er-osion measurement, the original tr-act maps give lot d;::p~~-1 ·r..o mean high r.ide, which is a somewhat ephemeral marker. The original ~~act maps, as filed with the County, ~how the lot depth to be 130 feet on th~ north side. and 140 feet on Che south side. The lot is shown to be gene=ally :-ectanguhar, with ~he seaward prope:-ty i;ne d::-awn straight and semi'- ,paralleJ.' to Pacific. There is no indict.£tion of the natural coastal cor:figu'fation, and no front-to-bluff mea~urements were recorded.

Past eros:lon rates ·between 9-9-56 and 8-5-70 were examined by flicker comparison of magnilied aerial photographs AXH-8R-58 C1956) and 05-SL0-41 C1970}. The erosion for this section of bluff during ,thi~ time per1od ~ds !ound to be negligible, elthough descrimination love ls are very poor d1~e to the great height of the f lyov~rs < 10, 000 f~~~ or so). Tne rock spur and cover on the north sid~ appear to ha-; ·'? a very similar configuration to that of today, in both:, cases.

The previous geologic reporc (Chipping Geological Servi~es, July 21, 1988> noted that erosion prior to the 1982/3 stotm season was probably. z,,,.a inches/ yr. This was supported by obsei;vation of th.: state of we~~hering in the bluff face, and is pres~ptl~ ~upported by existing conditions (August-September. 1989). H6~eyer the great waves of H182/3 resulted in high splash-up and erosion of the A, terrace deposits, and very high impact enefg.Jes on the bedrock. and W resulted in a bluff retreat of 4-5 feet ove~ a sp~ce of several seasons. ~t is esti~~ted that at least 12 feet of retreat has taken place in the ter~ace deposits along th~ northern property line since the 1982/3 ~eason, mainly due to restablishmont of a normal bluff slope following bluff undercutting during those storms

The long term erosion rate, g~4en an assumption of a single storm of 1982/3 intensity during the period, would be a maximum of 20 feet over a period of 50 to 75 yeal~z,

Projection of this erosion rate into the future must be made ~1i th extreme caution, due to possible sea level rise and ~torm track changes that will pr-obably be induced by global climatic warming. It is likely to produce more seasons 11ke ~hat of 1962/1983.

The about 25-30 feet between the bluff and the house could easily be removed by -erosion during the next 50 years. gi·.•er, the estim~ted erosion rates <see above).

Dear Te:d:

Pursua~t to our conversation o~-August 8, 1989, I have the fol­lowing additional information r:egarding the effect Of the pro­posed bluff protection structutes on the sand production of the }:)luff area.

In my opinion, ,the bluff top ero,sion is producing a substantial degr~~ of sedimentation, that is detrimental to the beach. The majority of erosion is occurring in the upper layer of the soils, ~ which are comprised mostly of clays and silts and are not signif- '1911' icant contributors to the beach sands. The construction of the proposed retaining wal)::;;1- a11d ri~ rap ~r--niamtlit will have no sig­nificant effect on sana production- -for this ar~~-
