INTRODUCTION ' 1.1 Authorization and Purpose ' In the Fall of 1992, the Overall Development Plan for the Paragon Point P.U.D. was submitted to the City of Fort Collins and subsequently approved. This development is situated adjacent to Fossil Creek, immediately south of SouthRidge Golf Course. Typical ' of many streams within Fort Collins, Fossil Creek has experienced significant changes in recent years. These changes can be partly attributed to the effects of development activities, tespecially with respect to increased runoff and sediment loads. Due to recent channel stability problems, an increased awareness regarding the impact of future development t activities on the stability of adjacent streams has developed. To quantify the potential effects of the Paragon Point P.U.D. and identify measures for mitigation of associated impacts, the City of Fort Collins has requested that a stability study of Fossil Creek in the ' vicinity of the development be conducted. ' The purpose of the stability study is two -fold: 1. Characterize the stability of the Fossil Creek channel between Trilby Road and ' Lemay Avenue based on an evaluation of hydrologic, hydraulic, geomorphic and sediment -transport characteristics of the stream; and ' 2. Develop practical improvements for mitigating adverse stability conditions in the stream. ' This report documents both the results of the stability analysis of the Fossil Creek channel and the work associated with the development of stabilization measures along the ' study reach. �I 1.2 Project Location and Summary of Existing Problems The reach defined for this study of the stability of Fossil Creek extends from Trilby Road upstream to Lemay Avenue. Although the investigation of channel bed and bank stability issues were limited to this reach, the nature of the quantitative bed stability analysis required that the hydraulic and sediment transport analyses be continued upstream of Lemay Avenue. The Fossil Creek study reach is located within the City of Fort Collins in the western half of Section 7 of Township 6 North, Range 68 West and is indicated in Figure 1.1. From Trilby Road upstream a distance of approximately 4000 feet, Fossil Creek 1 EAST HORSE TOOTH �4W5 Warre z Park, ZZ, -\c .1findale G-Off"course Warren L ke oG > Reservoir U 4991 r-11 --------------- - - L 50"NU co c) UJ Me ellands - 9 011. er Par RWOKROAD 050 z 6 L _Y' 4950 S Tr—u R C -Ne �re 0 (,I 0 12 U fl 0 ri IT Q L of T I L 14Y JOA Trailer qc�! _Park c r Z Figure 1.1. Location Map for the Fossil Creek Stability Study. 2 C I E passes through the currently developing Paragon Point, a primarily residential development. From the north end of Paragon Point upstream to Lemay Avenue, a distance of about 3300 feet, the creek is bordered entirely by the SouthRidge Golf Course. The primary motivating factor in the undertaking of this study, is the stability of the channel banks within Paragon Point. In this the southern portion of study reach, the channel is characterized by numerous meander bends and oxbows, and actively eroding, steep to nearly vertical banks which are up to 22 feet in height. Concern was expressed within the Stormwater Utility for the potential impact of the stream, due to further meandering and bank erosion, on the proposed residential development (particularly in relation to the bluff ' to the east of Fossil Creek). The channel plan form through the golf course is similar to that through Paragon Point and actively eroding banks are again evident; however, the banks are of lesser height (up to about 15 feet) and the potential for economic loss caused by an unstable channel and eroding banks is substantially lower. In addition to the culverts under Trilby Road and Lemay Avenue, one grade control exists within the study reach. This grade control is a concrete sill which forms the foundation for a check structure which is used in conjunction with irrigation pumping operations for the golf course. The check structure is located within the golf course reach approximately 2300 feet downstream of Lemay Avenue (1000 feet upstream of Paragon Point). Two additional grade control structures are currently under construction within the Paragon Point reach; these are concrete and riprap structures which are associated with two recently -constructed sanitary sewer crossings of Fossil Creek. Rock has been placed downstream of the Lemay Avenue culvert to provide both bed and bank protection through two severe meanders. This "riprap" consists of up to 3-foot diameter rocks which provide non -uniform coverage of the native material. Due to the use of this large material and the lack of a cohesive revetment system, this installation appears to be a partial cause of localized bank erosion as evidenced by a recently sloughed bank on the outside of the bend directly downstream of Lemay Avenue. Similarly, toe slope protection in the form of large diameter rocks has been placed on the outside of the bend directly downstream of the existing grade control within the golf course. Several factors may be contributing to the stability problems within Fossil Creek. These factors include: 1. Development of the golf course and the consequent seepage caused by irrigation of the course; 2. Realignment of the channel through SouthRidge Golf Course; 3 3. Backwater upstream of both Trilby Road and the existing grade control resulting from the constriction caused by the culvert and check structure, respectively; and 4. Urbanization upstream of the study reach resulting in a potential increase in stormwater and sediment runoff. This study investigated the impact of each of these factors in an attempt to determine the nature and degree of the instability problems within Fossil Creek. Alternative measures to mitigate the instability problems are also presented. 1.3 Data Collection and Field Investigation The field investigation completed in support of this study included numerous site visits by Lidstone & Anderson, Inc. (LA) to: (a) stake cross section survey locations, (b) identify areas of bed level changes including aggradation and incising, (c) locate and characterize areas of significant bank erosion, (d) collect both bed and bank material samples, (e) estimate channel and overbank roughness as it relates to flow resistance, and (f) identify natural and man-made controls along the study reach. Photographic documentation of existing conditions along the study reach was collected; these photographs are included in Appendix A. In conjunction with the LA field investigations, TST, Inc. surveyed 27 channel cross sections and ten zones of significant bank erosion. This information was analyzed to produce a 1992 thalweg profile, a 1992 HEC-2 model, and local bank profiles in the areas which exhibit the most severe erosion problems. The bank samples were analyzed by Terracon, Inc. to determine bank material gradation curves and other physical properties; gradation curves for the bed samples.were developed by the Engineering Research Center at Colorado State University. In addition to the efforts listed above, the Fossil Creek Master Drainageway Plan (SLA, 1982) was used extensively during this study to identify hydrology, characterize hydraulic conditions in the channel in 1982, relate bed levels along the study reach between 1982 and 1992, and compare water surface profiles from 1981 and 1992. 4 ' II. HYDROLOGIC AND HYDRAULIC ANALYSES 2.1 Hydrology ' The hydrology used in this study was defined based on the hydrologic analysis completed for the Fossil Creek Master Plan. The Master Plan included the development of a SWMM model for both existing and fully -developed conditions within the Fossil Creek ' watershed. Peak discharges were cited for the 2-, 5-, 10-, 50-, 100-, and 500-year return \ period events for both existing and developed conditions. For the purposes of this study, ' discharge profiles were identified for the 2- through 100-year events for both existing and developed conditions; these profiles are given in Table 2.1. ' The Master Plan provided flood hydrographs for the 2- through 500-year events for the concentration point 'Fossil Creek upstream of Lemay Avenue'; in addition, the technical addendum to the Master Plan furnished the 100-year flood hydrograph for the concentration point 'Fossil Creek upstream of Trilby Road'. The 2- through 50-year flood hydrographs upstream of Trilby Road were synthesized ' by multiplying the ordinates of the 100-year hydrograph by the ratio of the appropriate peak discharges. The 2- through 100-year hydrographs downstream of Lemay Avenue were ' estimated by multiplying the ordinates of the corresponding hydrographs upstream of Lemay Avenue by the ratio of the appropriate peak discharges. The three resulting families of hydrographs are presented in Appendix B (Figures B.1 through B.3). ' The hydrology defined in Table 2.1 and Figures B.1 through B.3 were used in conducting the hydraulic and channel stability analyses for this study. t ' 2.2 Hydraulic Analyses ' 2.2.1 General Although hydraulic analyses were completed in the Master Plan (using the U.S. Army ' Corps of Engineers Backwater Profile computer model -- HEC-2) for both existing and future conditions, these analyses were conducted using cross sections which were digitized ' from topographic information generated from 1981 aerial photography. Due to changes in (a) bed. levels, (b) the culvert configuration at Lemay Avenue, (c) plan form, and (d) channel cross sections, the 1992 survey information introduced in Section 1.3 was interpreted ' and formatted to create a 1992 existing condition HEC-2 model for the study reach. 5 Table 2.1.

The 1992 survey was limited primarily to the immediate vicinity of the channel; extensive surveying of the channel overbanks was not conducted. Consequently, the 1992 cross sections were extended to encompass the entire 100-year floodplain by using the available topographic mapping for the area. Through the Paragon Point Development, topographic mapping at a scale of 1" =100' with a contour interval of 1 foot was provided by TST, Inc.; this mapping is based on aerial photography dated September 1991. The available mapping through the SouthRidge Golf Course was provided by the City of Fort Collins at a scale of 1" =100' with a contour interval of 2 feet. Unfortunately, this mapping is not a completely accurate reflection of the existing topography as it is based on aerial photography dated April 1981 which predates grading of the golf course. It is also noted that, based on conversations with City of Fort Collins surveyor Mr. Wally Muscott, it was determined that during the 1980s the vertical datum in this area was lowered 1.69 feet. As a result, relative to the 1991 topography and the 1992 surveyed cross sections, the 1981 topography is situated 1.69 feet high. Consequently, when digitizing cross sections using the 1981 mapping, 1.7 feet was subtracted from each contour; this process usually resulted in smooth transitions between the surveyed cross sections and the mapped overbank elevations, the transitions generally would have included a vertical discontinuity if this adjustment had not been made. It is noted that field observations suggested that the flashboards associated with the existing check structure in the golf course would likely fail for even moderate flow events. Therefore, the cross section at the structure was assumed to be defined by the concrete sill only; the flashboards were not included in the model. The existing condition model was then modified to reflect current topographic changes in the vicinity of the proposed park within Paragon Point, and the two newly constructed grade controls associated with sanitary sewer crossings of Fossil Creek also within Paragon Point. This developed condition model, which includes the fully -developed condition hydrology presented in Section 2.1, was used to evaluate future condition hydraulics. Channel banks in the HEC-2 model . were defined to include primarily the active channel bed, with consideration being given to the variation in roughness across the cross sections. The result is channel bank locations which delineate changes in roughness as well as define the potentially active channel bed. Estimates of Manning's n values were made for the channel and overbanks based on field observations, standard guidelines for defining roughness coefficients, and engineering judgement. Channel n values were designated as varying from 0.032 to 0.035, while overbank roughness coefficients were estimated to range from 0.040 to 0.045. The 7 U 1 roughness coefficients selected for use in this study generally agree with those cited in the Master Plan; the values have been modified as necessary to reflect changes which have occurred during the intervening 11 years. It is noted that the overbanks within the floodplain in Paragon Point are generally covered with short to moderately tall (less than 6 inches to about 18 inches) native grasses and weeds with no major flow obstructions; within the SouthRidge Golf Course, the overbanks consist mostly of well-groomed lawn grasses, again with no substantial flow obstructions. It was assumed that the five existing golf cart bridges and four pipe crossings in the golf course would fail during large flow events and therefore were not considered to be flow obstructions. Starting water surface elevations for existing conditions were assumed to be identical to those given in the Master Plan; the stage -discharge rating curve cited in the Master Plan directly upstream of Trilby Road was used in this study. For developed conditions, the stage -discharge rating curve upstream of Trilby Road was determined assuming the proposed Trilby Road grade and culvert as specified in the Preliminary Drainage Report for Paragon Point (LA, 1991). Due to the storage effects resulting from the ponding condition upstream of the road, the routed 100-year water surface elevation upstream of Trilby Road cited in that IA report was used as one point on the stage -discharge rating curve. For the 2- through 10-year events, the proposed culvert was analyzed using the Federal Highway Administration (FHWA) procedure for the design of culverts. The HY-8 computer package, which uses the FHWA methodology was utilized for this analysis. Tailwater conditions for the culvert were specified based on the water surface profiles developed in the Master Plan downstream of Trilby Road. The 50-year water surface elevation upstream of Trilby Road was estimated by interpolating between the 10- and 100-year values. The analyses for determining the developed condition starting water surface elevations are included in Appendix C. The culvert at Lemay Avenue was analyzed within the HEC-2 model using the 'Special Culvert' routine; this procedure follows the FHWA guidelines mentioned above. The cross sections used in both the existing and future condition models are provided in the figures in Appendix D. 2.2.2 Hydraulic Analyses Associated with the Delineation of Floodulains The HEC-2 models for both existing and developed conditions were utilized with the corresponding 100-year discharge profile to estimate the 100-year flood profiles along the study reach. The existing condition profile was compared to the existing condition 100-year profile reported in the Master Plan with generally agreeable results (refer to Table 2.2). 8 Table 2.2.

(2) The 1982 water surface elevations are as reported in the master plan minus 1.7 feet to adjust for datum changes. 6 I The two locations where the two profiles disagreed substantially were upstream of the Lemay Avenue culvert (a result of the culvert replacement and enlargement), and within the golf course between Cross Sections 19 and 22 where it was noted that the Master Plan discharge in the HEC-2 model had been erroneously reduced by 300 cfs. The 100-year flood profiles for both existing and developed conditions, as estimated for this study, are shown on Sheet 1. The increase in water surface elevation from existing to developed condition is primarily due to the approximately 30 percent increase in discharge at the 100-year level. The difference in water surface elevation upstream of Trilby Road is also influenced by the proposed culvert and finished grade associated with Trilby Road. Floodplain boundaries were delineated on the available topographic mapping for the 100-year event for both existing and developed conditions. The floodplain boundaries within Paragon Point are shown on Sheet 2, while the boundaries within_ SouthRidge Golf Course are indicated on Sheet 3. It is noted that a significant discrepancy exists between surveyed Cross Sections 17 and 18 and the 1981 topographic mapping. The floodplain Zoodplain elevations and boundaries are believed to be accurate and reflect the topography indicated by the 1992 surveyed cross sections. However, due to inaccuracies of the 1981 topographic mapping, in relation to existing grades, the floodplain elevations and boundaries in the vicinity of these cross sections are not entirely commensurate with the mapping shown on Sheet 3. The existing condition water surface profile for the 100-year return period is given in Table 2.3; the HEC-2 output for the existing, 100-year analysis is included in Appendix C. The output for the developed condition analysis will be addressed in the following section. It is noted that downstream of the study reach, from the Union Pacific Railroad upstream to Trilby Road. The 100-year floodplain boundaries along Fossil Creek are currently being revised by Lidstone & Anderson, Inc. The modified boundaries will be presented in a revision to the Fossil Creek Master Drainageway Plan. 2.2.3 Hydraulic Analyses Conducted in Support of the Channel Stability Analyses ' In addition to the 100-year event, the 2-, 5-, 10-, and 50-year return period events for developed conditions were also modeled using HEC-2. Water surface profiles associated ' with these events are shown on Sheet 1; the water surface elevations are also given in Table 2.3. The profiles indicate that for events larger than that defined for the 2-year return period flow, Trilby Road will generate backwater through most of the Paragon Point ' Development.

The complete HEC-2 output for these analyses is included in Appendix C. (It is noted that low flow discharges of 100, 200, and 400 cfs ' were also analyzed to aid in defining the lower range of sediment transport capacities; the analyses for these flows are included in the HEC-2 output.) ' Profiles of the hydraulic parameters which influence sediment transport characteristics were produced for both the 2- and 100-year return period events. Channel velocity, hydraulic depth, and effective flow width profiles are given in Figures B.4 through B.6, ' respectively. Due to backwater effects in the study reach, the 2-year flow velocities are often greater than the 100-year velocities. For example, within the first 800 feet upstream ' of Trilby Road, 2-year velocities range up to nearly 6 fps while the 100-year velocities are less than 1 fps. Sediment routing reaches were defined based largely on the hydraulic ' parameter profiles; the reach delineation procedure is described in Chapter M. These sediment routing reaches are indicated on the hydraulic parameter profile figures. Hydraulic analysis results for all eight flows (including the three low flows) were used ' to generate both the bed material transport relationships and the bed material discharge rating curves; detailed sediment transport capacity analyses were conducted for the 2-, 5-, ' 10-, 50-, and 100-year return period events. 11 12 I r III. CHANNEL STABILITY ANALYSIS 3.1 General The Fossil Creek study reach, from Trilby Road to Lemay Avenue, is a complex system influenced by changing hydrology, the nature of both the bed and bank material, the existence of artificial grade control structures, the potential for channel bed armoring, and potential for lateral migration of the channel. Under uncontrolled conditions and without armoring potential, an alluvial stream will generally transport sediment at a rate which will satisfy its sediment transport capacity; a characteristic which is governed primarily by the size of the available bed material and the following hydraulic parameters: flow velocity, hydraulic depth of flow, and effective flow width. In this scenario, a stream responds according to sediment continuity principles. If at a particular location along a stream its sediment transport capacity is exceeded by the upstream sediment inflow, that location will experience aggradation as the stream deposits its excess sediment. Conversely, if at a particular location the sediment transport capacity of a stream is greater than the upstream sediment inflow, the stream will fulfill the sediment transport deficit by removing material from either the channel bed, banks, or both. In the case of Fossil Creek, lowering of the channel bed may be limited by the armoring process. In the existing condition, man-made vertical controls are present in the form of a check structure within the SouthRidge Golf Course, rock protection downstream of Lemay Avenue, and culverts under Trilby Road and Lemay Avenue. In the fully - developed scenario, the Trilby Road culvert will be replaced but will still act a grade control; two concrete and riprap sanitary sewer crossings of Fossil Creek will also act as grade controls. These controls have the effect of artificially holding the stream bed at grade; thereby increasing the potential for bank erosion and channel widening. The presence of the culverts may also create an environment of upstream sediment deposition while promoting channel scour and bank erosion at locations immediately downstream of the culvert. As a result, this channel stability analysis of Fossil Creek accounts for the presence of grade controls and culverts. In recognition of these bed level considerations, stability of the Fossil Creek channel is strongly influenced by bank erosion and lateral migration. Erosion of the banks may partially be a result of the stream's attempt to fulfill sediment transport capacity in response to the limited availability of bed material. However, in Fossil Creek bank erosion is primarily a function of local flow -induced shear stresses, particularly on the outside of bends or in zones of non -cohesive bank material, where flow impingement results in undercutting of the banks and mass wasting and failure of the overlying bank material. 13 ' Regardless of the cause, the process of bank erosion impacts sediment continuity response by contributing relatively large volumes of sediment over short periods of time in ' localized areas. Bank erosion coupled with lateral migration further complicate the sediment analysis of Fossil Creek as they are not continuous along the study reach. These ' processes are limited at many locations by vegetative cover or the lack of sufficient shear stress to remove bank material. In consideration of the complexity and diversity of the problems discussed in the ' preceding paragraphs, the channel stability analysis for Fossil Creek was approached in the following manner: 1. General geomorphic analysis. This portion of the analysis included the geomorphic investigation of the study reach and identification of the historical ' behavior of the channel. This analysis provided the framework for the subsequent quantitative analyses. ' 2. Bank erosion and lateral migration analysis. This evaluation included both qualitative and quantitative elements of historical and potential bank erosion which were then used to temper the results of the quantitative sediment continuity analysis. 3. Quantitative analysis. This analysis consists of performing: (a) a simple ' quantitative channel stability analysis (using Lane's relationship); (b) an analysis of incipient motion particle sizes; and (c) a complete sediment continuity analysis. The following sections summarize this methodology as it specifically pertains to Fossil ' Creek. 3.2 Bed and Bank Material Composition ' In order to characterize the material which comprises the bed and banks, six bed material and four bank material samples were collected at representative locations along ' the study reach. The samples were collected in September 1992; specific sampling locations are indicated on Sheets 4 and 5. ' Grain size distribution curves were developed for the six bed material samples based on a washed -sieve analysis conducted by the Engineering Research Center at Colorado State ' University. The bed material gradation curves are presented in Appendix E. A summary of the gradation curve characteristics is given in Table 3.1. The bed material in all six 14 Table 3. 1.

The samples were comprised of 60 to nearly 100 percent of fine gravels and smaller particles. ' Bed sample # 1 was collected at a location approximately 50 to 80 feet upstream of Trilby Road; at this location, local flow conditions largely influence the composition of the ' bed material thereby resulting in a bed material gradation that is not representative of material within the study reach. The material collected at this location was considerably finer than the other five bed samples. .Samples #2 through #6 exhibited similar grading characteristics and relatively tight banding of the various material sizes. Consequently, a single representative bed material gradation curve was identified for the study reach. This curve is indicated in both Figure D.1 and Table D.1 contained in Appendix E. In order to characterize the material which comprises the channel banks through the study reach, four bank material samples were collected at representative locations. The bank material samples were collected in September 1992; specific grab sampling locations are indicated on Sheets 4 and 5. Prior to conducting the bank sampling program, the entire channel reach was ' qualitatively evaluated to determine parent material, physiographic setting, bank stratigraphy, changes in material composition and behavior of the individual banks to ' channel adjustments. The purpose of this evaluation and the later bank sampling program was to distinguish individual bank characteristics which might influence the direction and magnitude of bank changes through time. ' The initial geomorphic reconnaissance suggested that there were two principal parent materials exposed in the channel banks: valley fill or floodplain deposits and weathered Pierre Shale. The channel banks and channel bank failure seem to respond differently to the two types of parent material. Within the valley fill deposits, local stratification was ' present but the stratification was not consistent throughout the study reach. The overall homogeneity of the valley fill material suggests a relatively consistent depositional history ' of the channel through the study reach. On this basis, the four sample locations were selected and "wash down' material was removed from the face of the channel banks. A,composite or "channel" sample, representing ' the general stratigraphy of the zone of interest\was collected from each bank.' Geotechnical analyses, including grain size distribution and Atterberg Limits were ' conducted on the four bank material samples by Terracon Environmental, Inc. Grain size distribution was based on a washed -sieve and in some cases a hydrometer analysis. A summary of the results of these analyses is presented in Table 3.1. The grain size ' distribution curves are presented in Appendix E. 16 ' Bank samples # 1 through #4 are poorly sorted sediments with a sorting index ranging from 1.21 to 1.55 phi. These materials are slightly better sorted than one might anticipate in a floodplain deposit thereby suggesting a certain degree of increased reworking and lateral migration during the 'valley fill' period of geologic time. Recent history of the ' channel is characterized by reintrenchment of the channel into that valley fill. Grading of bank samples # 1 through #3 is relatively consistent; these samples are moderately well graded. Conversely, sample #4 is poorly graded and reflects the influence of its parent ' material characteristics, the weathered Pierre Shale bedrock. The bank material of Fossil Creek through the study reach is predominantly low ' plasticity silt size material. Typically the clay fraction is absent. Plasticity indices (PIS) ranges from 8 to 14 in the floodplain deposits and 17 for the single weathered Pierre Shale ' sample. Recent samples from Mail Creek (Lidstone & Anderson, Inc., February 1991), where the valley fill ranged from in PI from 10 to 15 and the weathered shale ranged from 15 to 25, support this relationship. The slightly higher PI in the weathered bedrock is a ' reflection of the mineralogy of the parent material and the increase in kaolinite content. Additional soils, geologic data and soil strength properties are available in a 'Report ' of a Geotechnical Investigation For the Fossil Ridge Subdivision, Fort Collins, Colorado" (October 1991) and Report on a Soil Profile and Ground Water Evaluation for a Portion ' of the Paragon Point P.U.D., Fort Collins, Colorado (July 1992) prepared by Empire Laboratories. 3.3 Qualitative Geomorphic Analysis ' it Creek reflects the underlying geology of the The channel bank material along Foss C e ymg g gy ' project area. The study area is underlain by the Upper Member of the Cretaceous Age Pierre Shale Formation. Locally the Upper Member contains a thin resistant fine grained slightly calcareous arkosic sandstone member. In the southern section of the proposed ' development, this sandstone member is fossiliferous. Along the east bank of Fossil Creek, the resistant sandstone member is a ridge former. It is directly underlain by the fissile grey ' shale characteristic of the Pierre Shale. The Upper Member of the Pierre Shale was exposed on or near the channel bed in a construction excavation near Station 29 + 00. This unit consists of a grey concretionary silty shale containing thin (0.1 to 0.6 feet) discontinuous beds of resistant limestone to calcareous fine grained sandstone (calcarenite). The Pierre Shale outcrops are moderately to well weathered, fissile and to some degree, jointed grey shale. The weathered section of the U III C' 1 L 1 Pierre Shale is poorly exposed along the cut banks near Stations 39+00, 27+00, 16+50 and 3+00. The more distinctive unnamed sandstone member of the Upper Member of the Pierre Shale is predominantly exposed along the top of the ridge lying east of the creek at an approximate elevation of 4920 ft, msl. This unit was encountered in many of the Empire Laboratory borings on both the east and west side of the creek and was mapped as "resistant bedrock". Locally the unit strikes approximately N18E and dips 13 degrees to the southwest (Empire Laboratories, 1991). The unit is relatively thin, averaging approximately 10 to 20 feet in thickness. Fossil Creek has historically entrenched into the Pierre Shale to form its present valley. As the channel moved laterally across its floodplain, it formed the present day valley -fill deposits. Within the last 100+ years Fossil Creek has reintrenched into the valley fill deposits to form its present day incised channel. In 1991, Empire Laboratories completed 40 soil borings in the general area and prepared a "depth to bedrock" map (Appendix A of that report). LA's field observations confirmed the physiographic setting of the Fossil Creek channel. In general, bank material throughout the zone of interest was relatively uniform and exhibited little horizonation. 3.3.1 Purpose and Data Base The purpose of the geomorphic evaluation is to define the characteristics of the Fossil Creek drainage based on field reconnaissance, available data, and information. In particular the geomorphic analysis identified historical changes in plan form, zones of sediment production, local geology, geomorphic trends, and involved the collection of reconnaissance level field data on channel bed and banks. The results of this analysis are intended to provide a geomorphic basis for: (1) the determination of both short- and long-term trends of the Fossil Creek channel through the study reach, (2) the establishment of erosion buffer limits for current and future development along Fossil Creek, and (3) engineering design of channel stabilization measures. The geomorphic study particularly addressed the channel reaches downstream from Lemay Avenue to Trilby Road. A cursory reconnaissance level geomorphic evaluation was conducted upstream and downstream of the defined reach. Existing channel grades are controlled at both culverts and a weir structure located downstream of the pump station in the SouthRidge Golf Course. Although shale bedrock is at or near the bed of the channel at various locations, it does not serve as a grade control. The resistant sandstone member 18 1 is too high in the stratigraphic section to serve as a vertical grade control along this particular channel reach. Over the course of this study, the following data were reviewed and evaluated. 1.

From the Lemay crossing to Trilby Road the channel has undergone lateral migration within its floodplain. A general overview of the historical changes along Fossil Creek are presented in Figure 3.1. The figure establishes the approximate boundary of the pre-1970 channel with respect to the approximate alignment of the current channel. The current channel alignment is based on the 1987 photography. During the 1950 to 1956 period the plan geometry of Fossil Creek exhibited little change within the scale of the aerial photography. By 1969 the meander cutoff in the vicinity of Reach 1 (Figure 3.1) had begun to form. Similarly there began a northward migration of the meander at Reach 3 and a westward 19 Y W W 01) W U = J U O W Ir LLO.

' migration of the meander near Reach 4. Such activity continued through the 1981 period; in particular, the cutoff at Reach 1 was nearly complete. There was an decrease in the ' meander wavelength between Reach 1 and 2 and upstream of the Stone Creek confluence. At Reach 2, the meander pattern migrated to the south into a colluvial apron adjacent to ' the weathered Pierre Shale bluff. The sinuosity of Reach 3 and immediately downstream of Reach 3 increased and there was an overall increase in sinuosity and decrease in meander wavelength throughout the upstream reach between Reach 3 and 4. Between 1981 and 1987, the SouthRidge Golf Course was built, and channel realignment and certain channel stabilization activities took place. Specifically, the golf course work straightened Reach 4 (Figure 3.1) and filled what had been the active meander to the west of the 1987 channel. A pump station and a concrete weir and grade control was constructed upstream of Station 50+00. The purpose of the weir was to provide a backwater condition to provide sufficient water depth for the pump station. The net result of all of these channel straightening, realignment, and grade control construction activities has been downstream changes to the Fossil Creek system. Immediately below Reach 4 channel widening has occurred. In certain bank areas, there has been an increase in meander amplitude and a decrease in meander wavelength. During this period rock was placed in a number of locations and including downstream of the weir structure. During this period from 1981 to 1987 changes in plan form downstream of the golf course have continued to occur. The nature of these changes is basically unchanged and is characterized by a decrease in meander wavelength and an increase in meander amplitude through the processes of outside bank erosion. In Reach 1 these processes ultimately resulted in the completion of the meander cutoff and, ultimately, channel straightening. Downstream of this location, channel widening and an increase in sinuosity is occurring in response to the formation of the cutoff. An analysis of the channel profile (Figure 3.2), which compares the period depicted in the 1982 Fossil Creek Master Plan to the 1992 I A/TST survey suggests that there has been limited vertical movement of the channel bed. Upstream of the weir/grade control there has been approximately one foot of aggradation. Immediately below the reach straightened and "stabilized" by the golf course there has been slight degradation. In the vicinity of the tight meanders near Reach 2 and below Reach 3, there has been slight aggradation. This channel response is anticipated, where meander wavelength is decreasing and channel length locally increases. Over time such channel aggradation and increase in sinuosity may ultimately result in a meander cutoff. After the cutoff is formed, as occurred near Station 9+00, channel incision or bed degradation will often ensue. It is believed that the apparent degradation directly downstream of Trilby Road is probably due to the reporting of an erroneously high bed elevation in 1982. 21 i 1 1 1 1 1 1 1 O M Co �t 00 Co d- 00 00 't '*- 00 a� 00 0 00 a r- > 00 W Sri r- 00 It N n 00 v ai to 00 'r * Profile is as reported h i the Master w Plan mint is 1.7 feet to adjust for z datum ch, Lnge.

Comparison of 1981 and 1992 Bed Profiles. 23 u 1 Plan form changes are difficult to quantitatively estimate from the aerial photography available for this reach of Fossil Creek. The scale of the photography, coupled with distortion and lack of horizontal control affect the accuracy of the estimates. Typically the estimates of horizontal migration are confined to reaches with more significant channel bank movements and are verified by field observations of bank erosion and point bar development. On this basis it appears that there has been an increase in the rate of channel. migration, when comparing the 1980 to 1992 changes against the period extending from 1950 to 1980. During the earlier 30-year period the maximum movement ranged from 8 to 12 feet. During the latter 12-year period, as much as 16 to 20 feet of lateral movement may have occurred. The majority of this movement has been in either a southward or westward direction into the valley fill. Geologic conditions of the Fossil Creek valley impact both the direction and magnitude of plan form changes. Along the lower channel in Reaches 1, 2 and 3 (Figure 3.1), migration to the east is restricted by bedrock control; particularly the Pierre Shale outcrops along the ridge and adjacent to the incised channel. In at least one location, near Station 29+00, a construction excavation exposed Pierre Shale approximately one to two feet below the alluvial channel bed. Shale beds and thin beds of limestone were exposed in the lateral cuts associated with the manhole and sewer line crossing extending eastward up the hill. This bedrock material, though not necessarily resistant to erosion, is relatively more resistant than the valley fill deposits to the west. Based on an analysis of the valley morphology, lateral migration of the channel into the weathered bedrock comprising the bluff has not exceeded —30 feet during near term or post "valley fill" geologic time. 3.3.3 Bank Instability The bank stability along Fossil Creek is reflective of the . types of material which comprise the channel banks, the vertical loads to which the banks are subjected, seepage forces and the channel hydraulics which impact the toe of the slopes. The following discussion presents the historical magnitude of channel bank failure (erosion). Along specific reaches, channel bank erosion has ranged from being minimal to greater than 32 feet during a 40-year period. Based on the nature of the channel changes, including channel cutoffs, the rate of migration may increase. The bank stratigraphy along Fossil Creek through the study area is discussed in the previous sections. The valley fill deposits reflect a one -layer or typically homogeneous silt dominated material. The weathered shale bedrock is texturally similar, yet is more competent based on stratification and consolidation of the parent material. Due to the 24 ' homogeneous nature of the channel banks and the predominance of silt fraction material, the failure mechanisms are typically block or rotational block type failures. The failure ' planes are conjunctive with the natural prismatic structure of the soils, or in the case of the weathered bedrock, with the joint pattern of the rock. The ongoing, yet relatively slow t process of creep failures are presently occurring along Reach 3. Rotational slip and creep failures are related to seepage along the channel banks and may occur as interrelated phenomena. The mechanism of bank failure along Fossil Creek is three -fold and can include: ' 1. Failure of a bank due to the exceedance of a threshold height (i.e., vertical load) initiated by the downcutting of the channel profile. 2. Erosion or undercutting of the channel bank by the lateral migration of the channel. This is coupled by the loss of soil strength and the ultimate failure of ' the bank at some height less than a threshold bank height. 3. Increase in seepage to the channel bank, which results in loss of soil strength ' and similar to (2) above, the ultimate failure of the bank at some height less than the threshold bank height. ' Thirty-one individual banks were analyzed in the study area to determine threshold bank parameters. The results of this analysis are graphically presented on Figure 3.3. Bank ' heights ranged from a minimum near vertical height of 3.4 feet to a maximum height of 17.6 feet. Maximum bank heights from the toe of the slope to the top of the bank reached 21.4 feet. Average measured bank angles ranged from a minimum of 33.5 degrees to a maximum ' of 79.1 degrees. The data for this analysis were compiled from the August 1992 Fossil Creek survey by TST, Inc. The stability of the individual banks was confirmed by field ' observations in September 1992, coupled with the results of the historical geomorphic analysis of adjustments in plan form. Locations of individual bank -instabilities, as identified during field observations, are indicated on Sheets 4 and 5. The nature of erosion at each location, along with the potential for future loss of material, are summarized in Table 3.2. The critical bank height analysis suggests that the potential for bank failure is not only ' dependent on bank height but also bank angle. Typically where bank angles are steeper than 60 degrees, a threshold bank height ranges between 8 and 12 feet. At angles flatter ' than 45 degrees, the threshold bank height was not achieved. Most channel banks less than 33 degrees are moderately vegetated and stable. The stability fields presented in Figure 33 ' represent the existing site conditions and could be significantly influenced by an increase in vertical load, such as a placement of a structure directly on a bank or an increase in pore water pressure due to increased lawn watering or irrigation. 25 0 ■X � � 0 W ❑ ° m �- ■ ❑ z o ® � ® p 0 010 ° ❑ o ❑ X W 0- 00, a m ❑ CE Z Y Zrr- O m m LU J J m �.c �- cl: ui z Cn LE O ❑ )K 0 0 LO o C1l]:J) iHJIEH NNYO LO O Liz 00 LO CD Liz co CD r, co w LO� o w LO 0 LO v UJ J O Z LO o� m Liz N 0 CV LO O LO 0 0 26 Table 3.2 Summary of Bank Erosion Characteristics Bank Future Failure Erosion Mechanism Potential w.Location (lj ``;<' f2} 1 1/2 3 2 2 5 3 3 5 4 3 2 5 2 4 6 2 5 7 2 1 8 3 4 9 2 3 10 2/3 5 11 2 4 12 2 5 13 2/3 5 14 2/3 5 15 2/3 5 16 3 5 17 2 4 18 2/3 3 19 2 4 20 2 4 21 2 3 22 2 3 23 3 5 24 3 5 25 3 5 26 3 4 (1) Failure Mechanism 1: Rotational Slip 2: Plane Slip 3: Cantilever Bank Fa�ure Failure Erosion Mechanism Potential 27 2 5 28 3 4 29 3 3 30 2 3 31 2 4 32 2/3 5 33 3 5 34 3 3 35 3 5 36 1 1 37 2 4 38 3 5 39 2/3 5 40 3 4 41 3 5 42 3 3 43 2 5 44 3 4 45 3 4 46 3 5 47 2 4 48 2/3 3 49 2 5 50 2 3 51 3 4 52 2 3 (2) Failure Potential 1 - Least Potential 5,2�- Most Potential 27 u r. To confirm this qualitative investigation of critical bank height, a Culmann analysis of threshold bank height was performed. The Culmann equation analyzes the forces acting on a bank versus the forces resisting bank failure and can be simply stated as follows: = l 4c x sin 8 cos 6 } - Z (1) l y 1-cos(&- ) where R is the critical height; c is the shear strength of the soils, (b is the stable bank angle; 8 is the angle of the slope; y is the unit weight of the soil; and Z is the depth of the surface fractures. Soil properties for this analysis were derived from the Empire Labs reports (1991, 1992), the Fossil Creek bank material properties (Table 3.1) and field observations. In summary, the Culmann analysis estimated that for steep to near vertical banks with tension cracks developing near the crest, a threshold bank height of 12 to 14 feet could be derived. Bank observations suggest that this value may be lower and approach 8 to 10 feet. In summary, the theoretical Culmann analysis generally confirms, but may over predict the Fossil Creek bank stability data observed in the field. Typically banks steeper than 60 degrees (1H:1V) and greater than 10 to 15 feet in height are generally unstable. Where banks are less than 10 feet in height, over -steepening of the banks by local hydraulic forces will result in bank failure. 3.3.4 Buffer Limits The geomorphic analysis evaluated the historical trends of the Fossil Creek system. The period of record included a historical aerial photograph analysis, which spanned 37 years (1950-1987). The channel profile analysis spanned 11 years of record (1981-1992). Field observations and slope stability analyses carried the historic data base to 1992. Future trends of the system are difficult to predict and are dependent on the hydrologic and hydraulic influence of Fossil Creek and its numerous tributaries, future development trends, and land use planning. On a short term basis one can assume that outside bank erosion, channel cutoffs and the channel's propensity to increase its sinuosity and decrease its radius of meander curvature will continue. Further development and encroachment on the channel banks would impact the evolution of the system. For that reason 'buffer limits" should be established to protect man-made structures from the instability of the river system and to minimize the influence of man's activities on the acceleration of the channel response. 1 28 1 C 1 C As noted in the previous sections, the composition of the banks significantly impact the rate and magnitude of plan form adjustments. Erosion buffer limits on the east side of the lower reaches will be markedly different. These banks can maintain a greater vertical height and have historically been relatively resistant to erosion. The buffer limit on the east side of the creek has been established at 30 feet, based on the historical movement of the creek against the valley wall. This 30-foot buffer limit does not apply through the SouthRidge Golf Course where the east and/or north bank is not against bedrock. The buffer limit with respect to banks situated against valley fill accommodates the maximum 40-year extent of lateral migration adjusted to the recent increase in rate of migration. This distance was estimated at 40 feet from the toe of the channel bank. This figure does not assume any bank failure after the lateral migration occurs. To accommodate this, the Colman theoretical analysis and the strength characteristics of the soils establishes that bank failure will ultimately fail to an approximate angle of 33 degrees or 1.511:1V slope. A threshold bank height of 12 feet was assumed and reduced to the 1.5H:1V slope. On this basis the buffer limit for banks situated against valley fill was approximately 58 feet. This was adjusted site specifically on Sheets 4 and 5 to account for true bank height, potential meander cutoffs and floodplain conditions. 3.4 Sediment Transport Analysis 3.4.1 Routing Reach Delineation and Reach -Average Hydraulics The quantitative sediment transport analysis was conducted on a reach -by -reach basis using reaches which individually exhibit similar sediment transport characteristics. Since one representative bed material gradation curve was deemed applicable for the entire study reach (refer to Section 3.2), fifteen (15) sediment transport routing reaches were delineated based on the presence of grade controls, and similar hydraulic conditions. The hydraulic parameter profiles in Figures B.4 through B.6 were instrumental in delineating these reaches. The sediment routing reach limits are listed in Table 3.3. It is noted that the following reaches were identified as grade controls: 1. Reach 2. This reach consists of the Lemay Avenue culvert (a three -sided 32'W X 10'H reinforced concrete box) and an approximately 140-foot length of the downstream channel. The riprap bottom in this culvert, and in the downstream channel, acts a grade control. 29 1 1 1 1 1 1 1 1 1 1 1 1 1 Table 3.3.

Reach 6. This reach includes the concrete sill associated with the existing check structure within the golf course. It was assumed that the flashboards at this structure would fail for moderately -sized flow events. 3. Reach 9. This reach consists of the new sanitary sewer crossing at Station ' 35+50. The protective concrete casing and the surrounding riprap protection are both acting as a local grade control. ' 4. Reach 11. This reach consists of the new sanitary sewer crossing at Station 29 + 10. The protective concrete casing and the surrounding riprap protection are both acting as a local grade control. r k Based on the collected bed material samples and a cursory check of the hydraulic conditions in the channel, armoring potential exists along much of the study reach. The sediment continuity model used for this study includes an assessment of the armoring potential for each reach and accounts for the impacts should a reach become armored. Using the reach delineations identified in Table 3.3 and indicated in Figures B.4 through B.6, average hydraulic parameters were computed for each reach. Averages were determined for all five return period flow events and the three low flow events. The average hydraulic parameters for the 2- and 100-year return periods are summarized in Table 3.4. The effective flow width is often identical for. the two events; this is due to the maximum effective width being defined as the channel bank width, and the fact that the 2- year event in the study reach is generally associated with the bankfull flow. A full summary of the reach -average hydraulic conditions is provided in Appendix F. 3.4.2 Lane's Relationship Anal Prior to sediment continuity modeling, two less rigorous analyses were applied in order to further characterize channel stability tendencies. First, Lane's relationship was applied to the individual routing reaches. Lane's relationship states that sediment transport capacity is directly proportional to water discharge and friction slope, and inversely proportional to the size of the bed material. Lane's relationship takes the form: (2) where q is the sediment transport capacity, QV is the water discharge, 4 is the friction slope, and D50 is the median bed material size [2]. 31 I I I I I U I 11 I F 11 I I I I I Table 3.4.

I 32 r] The right-hand side of the above proportion was computed for each routing reach and the values for adjacent reaches compared. Based on the relative sediment transport ' capacities of adjacent reaches, each reach was identified as either aggradational or degradational. The results of this analysis are summarized in Table 3.5. It is important to ' note that Lane's relationship, and therefore these results, do not consider armoring potential and do not fully account for the existence of grade controls. However, the table indicates that the relationship generally reflects the bed level changes indicated in the bed profile comparison of Figure 3.2. The two areas where the Lane's analysis results do not agree with the comparison of ' 1981 and 1992 bed profiles (Figure 3.2) are upstream of both Trilby Road and the golf course grade control. It appears that the 1981 bed profile upstream of Trilby Road may ' have been reported erroneously high as the cross sections for the Master Plan were digitized from topographic mapping rather than surveyed. Consequently, Lane's result of the reach upstream of Trilby Road being aggradational is probably more reflective of actual channel ' behavior than the degradation shown in Figure 3.2. Upstream of the golf course grade control, the bed profile comparison indicates ' aggradation while Lane's results suggest degradation. The comparative bed profiles are probably more representative of actual conditions. Lane's result is likely in error because the analysis was based on a model which defined the grade control with the concrete sill only, rather than including the flashboards. It was assumed that the flashboards would fail for moderate and high flow events. It appears that the flashboards may remain, intact for ' lower flow events, such as those which have occurred since 1981; consequently, the model did not account for the entire backwater potential associated with the lower flow events. ' 3.4.3 Incipient Motion Analysis In addition to the Lane's relationship analysis, incipient motion particle sizes were ' investigated. The incipient motion (or critical) particle size is the size of material for which the forces producing movement exactly balance the forces which inhibit movement. Any ' flow condition which is equal or greater in severity to the incipient motion threshold condition would result in the transport of bed material. The incipient motion particle size ' is determined by relating the critical shear stress (computed using Shield's equation) to the actual skin friction shear stress for a given flow condition. Shield's equation for computing critical shear stress is: ' z = 0.047- - - D 3 (YB Yw) � ( ) 33 1 1 1 1 Table 3.5.

Actual shear stress due to skin friction may be computed using: To = '/a• f-p • (4) ' where zo is the shear stress due to skin friction in lbs/sf, f is the friction factor, p is the water density in slugs/cf, and v is the flow velocity in fps [3]. The friction factor can be approximated using: ' f 115.2- (np)Z = (5) (yb )1/$ ' where yh is the hydraulic flow depth in feet, and nP is the Manning's n coefficient for the particle [3], which can be computed using Strickler's equation: DP so (6) 26 where D90 is the size in feet for which 90 percent of the bed material is finer [2]. ' By equating t, and z, from equations (3) and (4), respectively, it is possible to compute the critical particle size D, This computation was performed for the 2- through ' 100-year events for each non -grade control reach. The results of this analysis are summarized in Table 3.6. The table indicates that the incipient motion particle size for the 2-year event ranges ' from 0.6 to 1.6 mm. For the 100-year event, the incipient motion particle size varies from less than 0.1 to 2.8 mm. Comparing these values to the representative bed material ' gradation curve, it is apparent that the maximum incipient motion particle size corresponds to a percent finer of about 44 percent. This indicates a very high potential for armoring for ' the entire study reach. Therefore, it would be anticipated that the study reach has only minor potential for significant bed lowering. 3.4.4 Sediment Continuity Analysis Using the developed condition hydraulic parameters and the representative bed ' material gradation curve for the study reach, bed material transport relationships of the form 35 1 1 1 1 Table 3.6.

In equation (7), q. is the bed material transport rate in cfs/ft, v is the channel flow velocity in fps, yh is the hydraulic ' depth in feet, and a, b, and c are multiple regression parameters. The bed material transport rate in equation (7) is the total bed material load which consists of both bed load ' and suspended bed load. The Meyer -Peter, Muller equation for bed load, and the Einstein formula for suspended bed material load were used to estimate the two components of the total bed material load. The total bed material load was computed for each hydraulic condition, and the parameters a, b, and c were determined using multiple regression techniques. The parameters a, b, and c for each reach are presented in Appendix G (Table G.1). Typical values for b and c normally range from 2.0 to 5.0, and -1.0 to 1.0, respectively. ' With only one exception, the Fossil Creek parameters fall within these ranges. The exception was in Reach 15 where the b parameter is slightly high at 5.97. The coefficients of multiple determination for the regressions indicate a highly satisfactory fit of the data ' with the bed material transport relationships. Using the bed material transport relationships, and the range of water discharges with ' associated flow velocities, hydraulic depths, and effective flow widths, sediment -water discharge rating curves of the form = A- (Q.)B (8) ' were developed for each of the 15 reaches. In equation (8), q is the total bed material transport rate in cfs, Q,„ is the water discharge in cfs, and A and B are regression parameters. The regression parameters for the power curve suggested in equation (8) were ' determined using a linear regression procedure applied to the logarithms of both water and sediment discharge. In many instances, it was appropriate to partition the range of water ' discharges and determine two or more power curve segments for a reach; each segment (or A-B pair) then has a maximum water discharge associated with it. The resulting rating ' curve for each reach is given in Table G.2; these rating curves have been plotted and are included in Appendix G. An inspection of these curves indicates that they closely match the computed sediment discharge values. The irregular shape of many of these curves is due ' to the impact of backwater conditions which tend to minimize the sediment transport capacity at the 10-year flow level. ' Separate sediment continuity analyses were conducted for each of the 2- through 100- year return period storm events. The reach upstream of Lemay Avenue was taken as the upstream sediment supply reach for the analysis. Armoring of the channel bed was accounted for in the sediment continuity model using the following equation: 37 ' AZ = 2-D,- I -1 (9) Pl ' where AZ is the armor depth in feet, and P, is the decimal percent coarser than the critical particle size D, in feet. The model allows degradation down to, but not below, the ' armor depth. The results of the analysis are summarized in Figure 3.4 and Table 3.7. It is noted ' that the values given in the table reflect the impact of an assumed porosity of the bed material of 0.4. The results indicate that in relation to bed level fluctuations the entire ' study reach is relatively stable. For the 2- and 100-year events, the maximum change in bed level was estimated to be 0.2 and 0.8 feet, respectively. The analysis demonstrated a potential for armoring of Reaches 12, 14, and 15 for the 5-, 10-, 50-, and 100-year events. ' The analysis of individual storm events described above provides insight into the short- term response of the channel to single events. The long-term channel response can be ' estimated by probability weighting of the bed level changes expected for each return period. The equation for computing the average annual aggradation or degradation depth for each ' reach takes the form D. = 0.015(D100) + 0.06(1)so) + 0.09(Dlo) + 0.50(4) + 0.65(D2) (10) where D, is the aggradation or degradation depth for return period i, and D. is the average annual aggradation or degradation depth. The average annual depths estimated for each reach are also provided in Table 3.7. The results again indicate a relatively stable ' reach with a maximum annual change in bed level of 0.4. feet. In summary, the various components of the quantitative channel stability analysis all indicate that the potential for bed level fluctuations throughout the study reach is relatively ' low. The channel tends to maintain its current bed level due to both having achieved a general equilibrium in sediment transport capacity and exhibiting a significant potential for ' armoring. This condition has not been entirely the result of natural forces as the hydraulic conditions in the channel are largely dictated by the flow constrictions at Trilby Road and ' Lemay Avenue, and to a lesser extent by the other three grade controls. Based on the behavior. of the channel it appears that the three grade controls probably have a relatively minor impact on the channel bed stability; the flow constriction caused by the Trilby Road culvert appears to be the man-made feature which most significantly impacts the behavior of Fossil Creek through the study reach. 38 to 00 Co co 00 't N Co 00 a� 0 Co o Co v w � Co ca n Co "t Co `8 REACH I 15 14 13 12 101 NUMBER 2-YEAR I 0 0 + 0' 0 EVENT - 10�� 0 0 0 0 0 ANNUAL Y w .X wV wZ w f O w -i a 0O 11 u.m yv 10 � H 7 8 3 NOO .5. 6 T _ 13.1 14 15 3 4 11.1 oo 2 3 w 2 to U AGGRADA TION 3 O joo� DEGRADATION. 3 N Z U STABLE S THAN co>- Cf 0 w .0.05' EL EV.

IIV. CHANNEL STABILIZATION ALTERNATIVES ' 4.1 General In the preceding chapters, the results of the channel stability analysis along with the mechanisms of bed and bank failure were discussed. This chapter will focus on the alternatives available to stabilize the channel. Depending on the nature of the problem, the ' alternatives can be generally classified as bed stabilization measures or bank stabilization measures. . ' 4.2 Bed Stabilization Measures Stabilization of the channel bed may be accomplished through a number of alternative measures. The purpose of these measures is to retard or limit the amount of erosion or ' degradation of the channel bed. In some instances, the bed stabilization alternative may be utilized to reduce the effective slope of the channel; thereby reducing the channel velocity tand promoting sediment deposition. Where channel slope changes are made, however, an evaluation of the short-term and long-term impacts must be conducted. For example, ' placement of a structure to reduce the channel slope may stabilize the bed, but it may also exacerbate upstream channel widening and bank erosion. In general, bed stabilization alternatives can be grouped into four categories: grade control structures, drop structures, check dams, and channel armoring. ' 4.2.1 Grade Control Structures As the name implies, this alternative is placed to control the grade or slope of the channel. Grade control structures consist of materials that will effectively resist the erosive ' forces associated with a given design flow event. The grade control structure will serve to (1) limit the migration of a headcut migrating upstream, and (2) maintain the grade of a channel bed that may be experiencing degradation. Example of grade control structures presently located within the Fossil Creek study reach are the concrete cap and riprap structures placed over the sanitary sewer crossings at Stations 29+10 and 35+30. Grade control structures are traditionally subgrade structures placed at or below the invert elevation of the channel bed. A typical diagram is provided in Figure 4.1. The depth ' of the structures must be greater than any lowering of the channel bed associated with local scour or the migration of a potential headcut.

' 4.2.2 Drop Structures Drop structures are commonly installed in channel reaches that are relatively steep ' and have high erosion potential. These structures tend to concentrate the fall in the channel in one location and allow for energy dissipation associated with the erosive flows. In ' general, the effective slope of the channel upstream and downstream of the structure is reduced. ' With respect to Fossil Creek, drop structures could be installed to reduce the effective slope in highly erosive reaches experiencing severe bed degradation. However, this is not the case within the study reach as general degradation or lowering of the channel bed is not ' apparent. More common within the study reach would be the placement of a drop structure in conjunction with channel realignment when the overall length of the channel has been reduced. A schematic diagram illustrating the details associated with a drop structure is provided in Figure 4.2. Typical construction materials include rock riprap, concrete rubble, ' or reinforced concrete. ' 4.2.3 Check Dams ' Check dams are installed in channels to reduce the effective slope upstream of the structure. Reducing the effective slope promotes a reduction in channel velocity; hence a ' reduction in channel erosion and an increased potential for sediment deposition. Important considerations in placement of a check dam in Fossil Creek include: (1) increasing the frequency of out -of -bank flows due to ponding upstream of the structure, (2) increased ' deposition creating the potential for increased channel widening, and (3) releasing flows with an increased capacity to transport sediment thereby increasing the potential for downstream ' bed and bank erosion. To ensure the channel flows stay within the channel, check dams should not exceed ' the height of the existing channel banks. Protection against channel degradation and scour below the check dam should also be provided. Typical details associated with this structure are provided in Figure 4.3. Check dams can be constructed from any erosion resistant ' material but generally consist of rock riprap.

It is often utilized to provide protection at culvert outlets, spillway outlets or transitions from storm drainage outfalls into the channel. Typical construction materials include rock riprap, grouted riprap, or reinforced concrete. A schematic diagram of outlet protection associated with a culvert is provided in Figure 4.4. ' 4.3 Bank Stabilization Measures ' Several techniques are available to mitigate the bank erosion and stability problems within Fossil Creek. These techniques may range from the placement of the conventional structural bank protection measures to biotechnical protection measures. Evaluation and selection of the most appropriate techniques requires an understanding of the nature and severity of the bank erosion at each location. I In general, the bank stabilization alternatives evaluated and considered appropriate for Fossil Creek were classified as follows: 1 1 �1 Twe of Problem Bed degradation, toe erosion Seepage Failure Mechanism Plane slip, cantilever Rotation slip Protection Measure Revetment, retaining walls, realignment Seepage drains Traditional structures that have been intentionally omitted include dikes and/or retards. These type of structures serve to direct the erosive forces of the flow away from the channel bank. Dikes are frequently utilized in large river systems consisting of defined channels with a large width -to -depth ratio. Due to the narrow configuration of the Fossil Creek channel coupled with the magnitude of the sustained flows, dikes are not a feasible or appropriate bank protection measure. 4.3.1 Revetments Revetments reduce bank erosion by providing a layer of material capable of resisting the erosive force of the flowing water. The more conventional revetment consists of a 47 r� 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Extend riprop to height of culvert or normal channel depth, whichever is smaller Riprop�thickness on channel side slopes equal to 1.5e50 TIT4.-.1 or flatterrferred 31 maximum ra Concrete cradle/cut off, ---•--A-.A As-A-11 PLAN PROFILE Downstream Channel End slope at 1=1 Granular Bedding Figure 4.4 Typical Schematic for Culvert Outlet Protection (Armoring) 48 ' variety of materials including rock riprap, concrete facings, slotted or cellular concrete grids, articulated blocks, rubber-tiremats, or gabion mattresses (Gray and Leiser, 1982). Alternate forms of bank protection that have proven successful include the application of biotechnical measures. In general, biotechnical slope protection systems consist of both structural and ' vegetative elements working together in a complementary or integrated manner (Gray and Leiser, 1982). Before deciding to use either structural or biotechnical measures, the extent of the ' bank stability problem (coverage) should be considered. If total bank protection is required, shaping or regrading of the bank to a stable angle is necessary. Stable slope angles will vary ' based on the type of revetment with a slope angle of 1.5H:1V for articulated concrete to not less than 2.5H:1V for rock riprap. Typical diagrams for various structural revetments are provided in Figures 4.5 to 4.7. Given the nature of the bank erosion in Fossil Creek, total bank protection is generally not warranted. The predominant form of bank loss results from undercutting of ' the bank at the toe of the slope. Consequently, bank protection measures that offer a solution to this form of erosion must be considered. Erosion of the toe of a slope may be prevented by the placement of toe riprap or other suitable materials/techniques. If mass wasting of the upper bank is likely, reduction ' in the bank slope and stabilization by means of vegetation or some form of biotechnical measure will be necessary. The placement of vegetation should consider the planting of native species. As indicated in Section 3.3.3, the stable bank slope within the study reach ranges up to about 70 degrees for banks less than 5 feet high; however, for the majority of channel banks within the study reach, the maximum stable bank slope is approximately ' 1H:1V. Regrading the channel banks to these limits should be accomplished prior to revegetation. Where upper banks require the placement of more substantial protective ' measures, biotechnical alternatives should be installed. Suitable forms of biotechnical protection include brush mattresses, branch packing, or cellular grids as presented in Figures 4.8 to 4.10. 43.2 Retaining Structures As an alternative to the placement of toe riprap, retaining structures can be installed. ' In essence, toe riprap can be considered a form of retaining structure (rock gravity wall). As with toe riprap, retaining structures placed at the toe of a slope promote stabilization by ' preventing mass movement and protecting the toe from scour and erosion. In general, the retaining structures discussed in this section combine a structural measure to protect the toe APPENDIX B I DEVELOPED CONDMON HYDROGRAPHS AND HYDRAULIC PARAMETER PROFILES L 1 1 DEVELOPED CONDITION HYDROGRAPHS AND HYDRAULIC PARAMETER PROFILES I 0 cq M 0 co N 0 N 0 00 .. j 3600 CFS I a _I 2980 CFS 100—YEA 0—YEA 1680 CFS 12 0 CFS 10—YEAR 5— EAR 690 CFS 2—YEAR 0 0. 4. 5. 6. 7.

Consequently; all the retaining structures can be considered a form of biotechnical slope protection. Retaining structures fall into two broad categories: (1) toe wall structures, and (2) toe bench structures. The differences in the two types of structure are illustrated in Figure 4.11. Selection of a suitable retaining wall for biotechnical slope protection depends on such considerations as site constraints, availability of materials, appearance of the wall, ease of construction, opportunities for incorporating vegetation into the structure and cost (Gray and Leiser, 1982). With regard to this study, retaining structures were classified into one of the following categories: 1. Rock gravity walls 2. Crib or bin walls 3. Gabion walls 4. Reinforced earth walls Schematics of each retaining structure are provided in Figure 4.12. 4.33 Channel Realignment In locations where excessive bank stabilization will be necessary to control bank erosion, channel realignment should be considered. These locations include reaches of the channel with very tight (small radius of curvature) meander bends with actively migrating banks or reaches where a meander cutoff is impending. A good example of a recent meander cutoff is the reach of Fossil Creek near Station 8+00. Before changing the alignment of the existing channel, the following items should be considered: 1. sinuosity and radius of curvature of the existing channel throughout the study reach; 2. channel geometry; 3. presence of artificial or natural grade control structures; and 4. existing channel slope through the channel section to be realigned. Sinuosity and radius of curvature should be selected to coincide with the results of the geomorphic investigation. To the maximum extent possible, the realigned channel should 56 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Original Slope i 2 Plants a Shrubs Reworked Toe -Wall Flattened Slope 1 Trees a Shrubs -ram t Original Slope Toe -Bench Structure /-Lo evel Bockfill rBench Figure 4.11 Schematic Diagram of Toe Wall and Toe Bench Structures CRIB WALL �K (masonry, rock, concrete) .rete GRAVITY WALLS GABION WALL Heintorcing Strips REINFORCED EARTH STRUCTURE Figure 4.12 Basic Types of Retaining Structures P n 1 incorporate the sinuosity and radius of curvature exhibited in the more stable reaches of the existing channel. Channel geometry should be consistent with the channels upstream and downstream of the realignment. Based upon the results of this study, the Fossil Creek channel should also be capable of conveying the channel forming discharge of approximately 690 cfs which corresponds to the 2-year flow event. If the channel realignment involves a reduction in channel length, hence an increase in slope, a grade control structure or drop structure may be required to maintain channel stability upstream of the proposed realignment. In addition, if a grade control structure presently exists within a reach identified for realignment, then the new channel should incorporate a grade control structure to minimize the potential for upstream bed degradation. Finally, bank protection will be necessary with relocation of the channel. To promote the stability of the new channel, a combination of vegetation or biotechnical measures should be implemented along the channel banks. 43.4 Seepage Drains Seepage on cut slopes is often a major cause of bank erosion. Although this is not evident within the study reach of Fossil Creek, a brief discussion of alternatives to control this problem will be presented. In general, techniques to control seepage can be grouped into methods to control shallow seepage versus deep-seated seepage. Shallow seepage can be controlled by the construction of seepage ditches in areas above the cut slopes. Figure 4.13 provides a schematic of a conventional seepage ditch. Where the seepage is deep-seated, alternatives to convey water from a cut slope include the placement of live fascine drains or gravel drains. Fascine drains consist of live branches wired into long, sausage -like bundles approximately 1 to 2 feet in diameter. The fasciae bundles are then placed into ditches and covered with soil (Schiechtl, 1980). The gravel drains involve the placement of a permeable material along the toe of the slope. In conjunction with the permeable material, a drain pipe is often placed to assist in conveying the seepage water away from the slope. Illustrations of the fascine drain and gravel drain are provided in Figures 4.14 and 4.15, respectively. Prior to the placement of either the fascine or gravel drain, the cut slope should be regraded to a stable slope angle. For this study, the maximum stable angle is approximately 1H:1V. In addition, vegetation of the graded slope is also vital to the establishment of a stable bank. 59 k 11 1 1 • ♦ • 4i ���• ���� �i FASCINE DRAIN BRANCH DRAIN POLE DRAIN ROCK DRAIN • �� • . � WIRE MESH DRAIN DOHLEN D-PIPE'DRAIN Figure 4.13 Types of Seepage Ditch Constructions (Schiechtl, 1980) r - 30- 40cm--4- 60 -80cm �-- 60 - 80cm --b— 1 gravel fill \ 1 " live plug (large cutting) dead Figure 4.14 Diagram of Three Types of Live Fascine Drains drain pipe wedge.

Stabilization alternatives that warrant U H consideration include, but should not be limited to those presented in the preceding paragraphs. The evaluation and selection of the most appropriate stabilization alternative will depend on several factors. These factors include: (a) type of erosion (bed versus bank); (b) cause of the erosion (seepage, undercutting of the toe, etc.); and (c) location and severity of the erosion. At each location where the need for a stabilization measure has been identified, site characteristics and constraints, feasibility and ease of construction, and availability of materials and maintenance requirements should all be considered. Additional factors that must be considered in the final evaluation and selection of alternatives include: (1) impact on wildlife and threatened and endangered species, (2) permitting requirements, (3) the need for additional right-of-ways and easements or the acquisition of property, and (4) safety issues associated with placement of structures in an urban environment. 63 1 V. SUMMARY AND RECOMMENDATIONS Both qualitative and quantitative channel stability analyses were completed during the course of this study to evaluate and characterize the stability of the Fossil Creek channel between Trilby Road and Lemay Avenue. In addition, various bed and bank stabilization alternatives were presented as possible improvement options in the event stabilization efforts are found to be necessary within the study reach. The results of the study indicated that with respect to bed level fluctuations the Fossil Creek channel within the study reach is relatively stable with minimal potential for significant downcutting of the bed. This condition is primarily a result of both the presence of man-made grade controls and a high potential for armoring of the channel bed. In light of this result, it is generally recommended that additional grade controls not be placed within the study reach. Because of the geomorphic setting and hydraulic conditions, artificially holding the bed at or above grade may exacerbate upstream channel widening and bank erosion. If natural or man-made processes result in channel straightening in the reach, grade controls may considered if general scour is observed; however, the high potential for armoring would likely inhibit significant channel downcutting. The results of the bank stability analysis indicated that within Paragon Point the potential for bank failure varies from the east to west bank. Along the east side of the channel, against the bluff, the critical bank heights tend to be greater and the stable bank slopes tend to be steeper than on the west side. In addition, there is greater potential for the channel to migrate to the west than into the bluff to the east. The analysis of historical aerial photographs demonstrated that, in the locations with the highest banks, the current channel alignment is at its eastern -most position of the last 40 years. The general tendency at the present time is for the channel to migrate to the west. The consequence of these observations and results is that a wider erosion buffer limit is generally provided along the ``J°�,Pasf side of the channel. Analysis of aerial photographs dating from 1950 to 1987, and field observations during 1992 form the basis for delineation of the erosion buffer limits shown on Sheets 4 and 5. Consequently, if the creek is left in its current state, these boundaries represent the maximum expected extent of channel migration and bank erosion along the study reach which may occur over the next 40 years. It is recommended that structural improvements not be allowed within the buffer limits unless bank protection measures are implemented. If it becomes necessary to safeguard improvements which already exist within the buffer limits, bank protection measures may be used to effectively narrow the envelope of potential channel migration and bank erosion. 64 ' Specific bank erosion protection measures are not recommended at this time; however, if property or structures become endangered by bank erosion, the protection measures presented in Chapter IV provide several alternatives for stabilizing either portions of or entire banks as required. It is recommended that before implementing any stabilization ' measures, an analysis be conducted of the measures under consideration in order to assess the potential for adverse impacts either upstream or downstream of the affected area.
