1 Little Thompson Watershed Restoration Coalition (LTWRC) Floodplain Rehabilitation Planning Grant Application (Priority 2 of 3) #8 Describe the proposed purpose and scope of the plan, study, or analysis, including deliverables and outcomes. (12,000 character limit) Purpose The purpose of this Floodplain Rehabilitation Planning Project is facilitate rehabilitation of the floodplain in two high-priority areas along the Little Thompson River known as the Berthoud and Blue Mountain neighborhoods. Although flood-related damage is evident throughout the Little Thompson River, these sites represent areas of extensive damage that span multiple properties. Floodplain rehabilitation in these areas was identified in the Little Thompson Watershed Master Plan (2014) as a priority for improving the overall flood resiliency of the watershed, in addition to improving stream health, mitigating future flood and geomorphic hazards, and rehabilitating damaged infrastructure and property. Outcomes This planning project will develop conceptual scopes of work and plans 1 to address the flood recovery priorities identified in the Little Thompson Watershed Master Plan for the Berthoud and Blue Mountain reaches of the Little Thompson River. It will also provide guidance to the LTWRC for final engineering and project implementation, and meet the needs and desires of the local communities for ongoing flood recovery measures. Floodrelated impacts at these two sites were significantly exacerbated due to bridge crossings. Conceptual planning to modify or replace these bridges is critical to improving the watershed s resiliency from future flood events. Background This work will build upon another separate CDBG-DR Planning Grant Application currently being submitted by the LTWRC, Sediment Transport and Geomorphic Assessment (Priority 1 of 3) which will inform the LTWRC on essential sediment-related issues through hydraulic and hydrologic modeling and analysis. This project will also utilize October 2014 LiDAR and topographic data currently being prepared by the U.S. Army Corps of Engineers, for use by the CWCB in their floodplain mapping efforts, as well as the results of the hydrology study already completed by CDOT. The results will support the development of the hydrographs needed to model proposed bridge modifications and to prepare recommendations for restoration. Sharing this data, model and study results is a benefit to this proposed effort in terms of cost and savings, and continuity between the assessments. 1 Per CDBG-DR requirements, these funds are requested for conceptual design, not to exceed 30% of project design work. 1

2 Project Locations and Damages Located in the northern Front Range of the Colorado Rockies, the Little Thompson River is a unique and beautiful river system flowing more than 50 miles from its headwaters in the Roosevelt National Forest to its confluence with the Big Thompson River. Little Thompson Watershed (Source: Little Thompson Watershed Master Plan, 2014) Priority Site #1, Berthoud Neighborhood This site is between Stations and on the Little Thompson River, as shown in the Little Thompson Watershed Master Plan.. This reach is about 4,000 feet in length spanning through two bridges, one on West County Road 4 and one on Mountain River Road. The river alignment in this reach includes one bend at the West County Road 4 Bridge that is in excess of 90 degrees. This bend in combination with the narrow bridge significantly reduces the channel capacity as evident by the wide-spread flooding in this location and downstream bank scour. Immediately downstream of the West County Road 4 Bridge the eroding bank threatens the foundation of an existing silo. The second bridge, located at Mountain River Road has a very small vertical opening, likely the result of the sediment accumulation at the bridge. Lateral flooding at this bridge from the September 2013 event was extensive, spanning over 1,000 feet, leaving behind excess deposition that has rendered the adjacent agricultural fields unusable. The Eglin headgate also suffered flood related damage and cannot be used for irrigation 2

3 diversions, and both West County Road 4 and Mountain River Road were flooded and impassable. The goals for restoration at this site is to improve the hydraulic and sediment connectivity through this reach, reduce future flood impacts on agriculture operations, minimize or reduce flood impacts on the roads, and stabilize the banks, particularly in the vicinity of the silo. Berthoud Neighborhood Priority Site #2, Blue Mountain This reach of the Little Thompson River is some 10,000 feet in length from Stations to as identified in the Little Thompson Watershed Master Plan and includes the river crossing at Stagecoach Trail. This reach experienced significant scour from the 2013 flood and with peak flows measuesed at more than 15,000 cubic feet per second (cfs). Most of the vegetation was lost due to scour and there was significant disturbance to the floodplain. Several buildings were destroyed, including several barns and many outbuildings, including a shipping container used by the fire department for storage. Several existing buildings are still in danger from bank instabilities. The Blue Mountain neighborhood consists of about 300 to 400 people in about 100 full- time, year-round round homes with over 20 miles of dirt roads on the southern end of Larimer County. The Blue Mountain neighborhood is served by a single river crossing at Stagecoach Trail road, consisting of three circular concrete culverts estimated to be 60 inches in diameter, a concrete weir overflow spillway, and three 24-inch metal culverts 3

4 put in as a temporary crossing after the 2013 flood and is still in use today; this element also serves as an emergency overflow. This bridge plugged during the 2013 flood and flows overtopped the road rendering it impassable and isolating the community for an extended time period. Anecdotal information indicates this bridge has overtopped three times in the past 20 years, likely due to its configuration and limited capacity. Restoration is also recommended near River Way road, which is approximately 1.5 river miles downstream of Stagecoach Trail. This reach is located on a sharp bend, and erosion and scour in this area were extensive. In some locations, the floodplain dropped by at least 8 to 10 feet. Many structures were lost and one home was, and still is, threatened by a destabilized bank. Restoration recommendations in the River Way area include reconstruction of the river channel banks, reconstruction and stabilization of the overbanks, and bank stabilization to protect the home. Lastly, between the upstream and downstream limits of this reach (Station to ) the 2013 flood moved laterally to such an extent that it totally destroyed one home and significantly encroached on a second home. Restoration here includes floodplain grading and stabilization. The following satellite imagery is from the Master Plan, and highlights the extent of damage, and the current proposed floodplain rehabilitation measures in these reaches. 4

9 #9. Identify how this project will incorporate resilience and sustainability strategies. Include details on proposed resilience metrics and standards that will be tracked and reported. (12,000 characters) In the Little Thompson Watershed, the disastrous results of the 2013 flood, and subsequent scientific and planning efforts, have shown there is much work to be done to achieve a healthy, resilient river system that protects both life and property during and after flood events. The Little Thompson Watershed Master Plan states that, The goal with resiliency planning is to break the disaster-rebuild cycle by developing new approaches to restoration that provide improved methods for flood response, thereby making the river system more resilient to extreme flow conditions. The Master Plan goes on to state that, river restoration projects that might be considered in terms of providing improved resiliency include the relocation of structures from the floodplain, single-span bridge replacements of existing culverts, expanding the riparian corridor with native vegetation, revised floodplain regulations, and increased setbacks, among a variety of other actions. This proposal seeks to achieve these recommendations by developing conceptual plans with the following resiliency strategies: 1. Relocate structures out of the floodplain (to be determined); 2. Design single-span bridge replacements of existing culverts (e.g., Stagecoach Trail); and 3. Expand the riparian corridor with native vegetation (e.g., bio-engineered bank stabilization). Proposed Resilience Metrics and Standards Proposed resilience metrics and standards for this project include: Short-term (18 months) Conceptual floodplain rehabilitation plans completed for Berthoud and Blue Mountain neighborhoods; Conceptual plans include improvements or single-span bridge replacements of existing culverts; Conceptual plans include scopes of work for bio-engineered bank stabilization, to include grading and stabilization of the floodplain and headcut areas; and Improved community understanding and engagement regarding conceptual plans. 9

10 Long-term (+18 months) Detailed engineering, funding and implementation of proposed conceptual plans; and On-going community understanding of the river corridor and associated risks. #10 Please identify how your plan, study, or analysis will be implemented or used, including how it fits into local or regional planning efforts or processes, if applicable. Watershed coalitions should how the project aligns with the watershed master plan. (12,000-character limit) The purpose of this Floodplain Rehabilitation Planning Project is facilitate rehabilitation of the floodplain in two high-priority areas along the Little Thompson River known as the Berthoud and Blue Mountain neighborhoods. Floodplain rehabilitation in these areas was identified in the Little Thompson Watershed Master Plan (2014) as a priority for improving the overall flood resiliency of the watershed, in addition to improving stream health, mitigating future flood and geomorphic hazards, and rehabilitating damaged infrastructure and property (see satellite images in Question #8). This planning project will develop conceptual scopes of work and plans to address these flood recovery priorities. It will also provide guidance to the LTWRC for final engineering and project implementation, and meet the needs and desires of the local communities for ongoing flood recovery measures. This work will build upon the Sediment Transport and Geomorphic Assessment project being proposed under a separate CDBG-DR planning grant, which will inform the LTWRC regarding essential sediment-related issues and hydraulic and hydrologic modeling and analysis. The LTRWC subcontractors will also utilize October 2014 LiDAR and topographic mapping currently being prepared by the U.S. Army Corps of Engineers. This mapping is being prepared for CWCB for use in their floodplain mapping efforts. Sharing of this data, models and study results is a benefit to this Floodplain Rehabilitation Planning project effort in terms of cost, time and continuity between the assessments. This project also proposes to utilize the results of the hydrology study already completed by the Colorado Department of Transportation (CDOT). The results will support the development of the hydrographs needed to model proposed bridge modifications and to prepare recommendations for restoration. Again, sharing the hydrology study is a benefit in terms of cost, time and continuity between the two assessments. 10

13 C. NEED #12 Please provide data to describe a) the extent and severity of the disaster damage, and b) current conditions that pose a threat to health, safety, and welfare of the community. (12,000 character limit) In September 2013, the Little Thompson River experienced a catastrophic flood event with peak flows of approximately 15,000 cubic feet per second (cfs) as measured at Pinewood Springs some three times the projected 100-year flood event for this section of river. High flows combined with the extended duration of the flood resulted in significant changes in the river corridor, along with substantial infrastructure and private property damage. In various locations, the river migrated horizontally, experienced significant deposition, cut new overbank channels, rerouted itself through old gravel pits, left portions of pre-flood channel dry, lost much of its previous ecological function, and migrated or scoured to the point of destroying numerous irrigation diversions, roads, embankments, bridges, and other infrastructure. Although there have been other floods on the Little Thompson River, none have been as destructive as the September 2013 event. According the Little Thompson Watershed Restoration Master Plan, 30 homes were totally lost or rendered uninhabitable; five dams failed; 28 bridges were damaged or destroyed, isolating several communities for extended time periods (and requiring air evacuation); and there was a significant loss of agricultural land and livestock. The flood destroyed almost the entire riparian corridor, through surges of scour, deposition, or both. The upper reaches experienced almost a total loss of trees, many of which were large, well-established fir trees. The lower reaches experienced deposition of debris and sediment to such an extent that much of the riparian vegetation was buried beyond recovery. Although other rivers on the Front Range of Colorado also experienced catastrophic flooding from the September 2013 event, the Little Thompson River had some of the highest flows per square mile (unit discharge) of any other watershed.

14 Current Conditions: Priority Site #1, Berthoud Neighborhood Post-flood, the river alignment in this reach now includes one bend at the West County Road 4 Bridge that is in excess of 90 degrees. This bend in combination with the narrow bridge in the same reach, significantly reduces the channel capacity as evident by the wide-spread flooding in this location and downstream bank scour. Immediately downstream of the West County Road 4 bridge, the eroding bank threatens the foundation of an existing silo. The second bridge, located at Mountain River Road has a very small vertical opening, likely the result of the sediment accumulation at the bridge. Lateral flooding at this bridge from the September 2013 event was extensive, spanning over 1,000 feet, leaving behind excess deposition that has rendered the adjacent agricultural fields unusable. The Eglin headgate also suffered flood-related damage and cannot be used for irrigation diversions, and both West County Road 4 and Mountain River Road were flooded and impassable. Bank instability still threatens various structures, including a silo, in this reach. To date, no comprehensive channel realignment, revegetation, permanent infrastructure replacement, bank stabilization or other significant flooplain rehabilitation has occurred. Current Conditions Priority Site #2, Blue Mountain This reach experienced significant scour from the 2013 flood with peak flows measured at more than 15,000 cubic feet per second (cfs). Most of the vegetation was lost due to scour and there was significant disturbance to the floodplain. Multiple buildings were destroyed, including several barns and many outbuildings, as well as a shipping container used by the fire department for storage. Several existing buildings are still in danger from bank instabilities. The Blue Mountain neighborhood consists of about 300 to 400 people in about 100 year-round homes located on some 20 miles of dirt roads in the southern end of Larimer County. The Blue Mountain neighborhood is served by a single river crossing at Stagecoach Trail road, consisting of three circular concrete culverts estimated to be 60 inches in diameter, a concrete weir overflow spillway, and three 24-inch metal culverts put in as a temporary crossing after the 2013 flood and still in use today. This element also serves as an emergency overflow currently. This bridge plugged during the 2013 flood and flows overtopped the road rendering it impassable and isolating the community for an extended time. Anecdotal information indicates this bridge has overtopped three times in the past 20 years, likely due to its configuration and limited capacity. While temporary culverts have been placed in the river to provide community access, these are still in use today. Bank instability still threatens various structures. To date, no comprehensive channel realignment, revegetation, permanent infrastructure 14

15 replacement, bank stabilization or other significant flooplain rehabilitation has occurred in this reach. #13 Describe how this plan, study or analysis address the conditions described in question 12. (12,000 character limit) This planning project will develop conceptual scopes of work and plans 2 to address the flood recovery priorities identified in the Little Thompson Watershed Master Plan for the Berthoud and Blue Mountain reaches of the Little Thompson River. It will also provide guidance to the LTWRC for final engineering and project implementation, and meet the needs and desires of the local communities for ongoing flood recovery measures. Conceptual plans will address the conditions described in Question #12 via the following: Revised channel design (alignment); Bio-engineered bank stabilization, such as coir lift bank protection and installation of woody debris, grading and stabilization of the floodplain and headcut areas; Improved irrigation diversion headgates; Improvement or replacement of bridges, as necessary; Incorporation of recommendations being developed under the proposed Sediment Transport and Geomorphic Assessment planning grant, including planform recommendations and site-specific recommendations for reducing impacts on the restoration elements from excessive deposition and/or erosion; and Conceptual cost estimates. Public outreach and landowner input will be an important part of this project, and will be accomplished through working sessions at each stage of the conceptual design process. Coordination with State, Federal and local agency representatives (i.e., USACE, NRCS, USGS, USFS, CWCB, County and Town staff, CDOT) is also a key part of successful project completion. The LTWRC and its subcontractors will solicit input on all conceptual plans, including input regarding permitting and approval requirements, to ensure consistency with general expectations of this Floodplain Rehabilitation Planning Project. 2 Per CDBG-DR requirements, these funds are requested for conceptual design, not to exceed 30% of project design work. 15

16 Other project components, such as fieldwork, updated mapping, and hydraulic modeling, will provide the project team with sufficient and accurate data to develop their conceptual plans and scopes of work. #14 Demonstrate how you concluded that alternative funding sources are not available (e.g., which funding sources might this project be eligible for and why you concluded those sources would not work.) 3,000 character limit GORDON G D. IMPACT #15 Identify how this plan, study or analysis furthers or is compatible with local and/or regional planning efforts (including watershed master plans, as applicable) (12,000 character limit) The Little Thompson Watershed Master Plan was finalized in December The Master Plan includes the main stem of the Little Thompson River, the West Fork tributary, and the North Fork tributary, as defined by U.S. Geological Survey (USGS) topographic maps. The Master Plan was designed to provide a tool for guiding the LTWRC, the counties, and local communities for reconstruction of structures and infrastructure and restoration of the river and the riparian corridor. The Master Plan was created to identify needs, support long- and short-term recovery and planning decisions, facilitate future funding opportunities, and present conceptual recommendations that incorporate strategies to increase resiliency against future floods. This proposed project aligns with the goals identified in that Plan, specifically: Infrastructure and road and bridge reconstruction, associated bank stabilization, and bank stabilization for protection of homes and utilities; and Preservation of river, wetlands and floodplain corridors. Currently, the LTWRC is also seeking funding for two additional CDBG-DR planning studies: 1. Sediment Transport and Geomorphic Assessment (Priority 1 of 1); and, 2. Habitat Study (Priority 1 of 3). In addition, the LTWRC is also plans to request grant funds from the following: 1. INSERT CORRECT NAMES HERE These proposed planning studies are being strategically advanced to address the multiple flood recovery planning components that need to occur throughout the 16

17 watershed, before comprehensive flood recovery implementation projects can begin. These proposed planning studies and evaluations will help provide the technical basis for long-term strategic decisions that protect both public and private infrastructure, and the natural resources of the region. The proposed Little Thompson Floodplain Rehabilitation Project is a critical component in the data collection and planning process for the Little Thompson watershed as a whole. #16 Describe the multiple objectives the project will address (e.g., hazard mitigation, green infrastructure, economic and community development) This project seeks to achieve multiple flood recovery objectives and benefits. Generally, these objectives include hazard mitigation, green infrastructure, improved safety, environmental enhancement and sustainability, and economic and community development. Hazard Mitigation Under development Green Infrastructure Under development Environmental Enhancement The 2013 flood destroyed almost the entire riparian corridor of the Little Thompson River, through surges of scour, deposition, or both. The upper reaches experienced almost a total loss of trees, many of which were large, well-established fir trees. The lower reaches experienced deposition of debris and sediment to such an extent that much of the riparian vegetation was buried beyond recovery. This project is the key first step in coordianted environmental enhancement and recovery of these priority reaches of the Little Thompson. Proposed enhancements include revised channel design (alignment) and bio-engineered bank stabilization, such as coir lift bank protection and installation of woody debris, grading and stabilization of the floodplain and headcut areas. Economic and Community Development While it is impossible to prevent another natural disaster, risk-based planning such as is proposed here, can reduce the economic impact of future flood events. Preparing conceptual plans helps the LTWRC avoid loss of life and protect investments. Risk assessment, master planning, and data collection and mapping are all important hazard mitigation tools to reduce vulnerability, promote economic growth, and ensure natural resource protection. Connectivity issues will be address via preparation of conceptual plans to rehabilitate the floodplain upstream of Stagecoach Trail crossing to incorporate river resiliency with 17

18 a community facility that provides public access, recreation and connectivity to the river. It will also evaluate construction of an offline pond to provide fire suppression, fish refuge, and an amenity for the neighborhood. #17 Please demonstrate commitment, involvement, and support for the plan, study or analysis from community partners, the public, and/or neighboring jurisdictions. As applicable, identify what each partner will contribute (e.g., subject matter expertise, funds, shared decision-making etc) (12,000 character limit) Letters of support are attached to this grant application from the following entities: #18 Describe how this project intends to address or positively affect vulnerable populations, if applicable. (6,000 character limit) One definition of a vulnerable population could include those currently living or working inside a high hazard floodplain and channel migration zone. Not only have these populations already suffered significant property damage, loss or harm, but they may be at high risk of repeat damage in future flood events. The floodplain mapping, infrastructure redevelopment, revegetation and bank stabiliization proposed as part of this project, will provide direct benefits to these affected populations. For property owners in the Little Thompson floodplain, these maps and conceptual plans will serve as an important educational tool for informing landowners and residents of their risk for the purposes structure reconstruction or removal, insurance, as well as evacuation and life safety. #19 Describe how this plan, study or analysis contributes to the overall economic health of the community, as applicable (12,000 character limit) Amidst the destruction, it is hard to see a disaster as an opportunity. But it can be an opportunity to build back better. Repeated flooding that impacts large portions of the local population, is detrimental to the overall economic health of the community. If local structures continue to be at high risk of inundation or erosion, their condition can deteriorate and property values decline. Repeat flooding is detrimental to businees owners and farms who have to close up shop, or stop work, to restore and replace damaged inventory or crops and lost livestock, each time a flood hits. Catastrophic flood events in a floodplain that is not resilient, can be enormously damaging to the local riparian ecosystems, negatively impacting fish, wildlife, and vegetation. This further degrades the economic health of a 18

19 region such as the Little Thompson watershed, which relies upon the beauty and health of its natural resources to drive property values and support wildlife and fisheries. While it is impossible to prevent another natural disaster, risk-based planning such as is proposed here, can reduce the economic impact of future flood events. Preparing conceptual plans helps the LTWRC avoid loss of life and protect investments. Risk assessment, master planning, and data collection and mapping are all important hazard mitigation tools to reduce vulnerability, promote economic growth, and ensure natural resource protection. #20 Describe how your plan, study or analysis addresses carbon mitigation and energy efficiency (6,000 character limit) This project does not directly address carbon mitigation or energy efficiency. #21 Describe how your plan, study or analysis addresses connectivity (trails, wildlife habitat, roads, etc) (6,000 character limit) Conceptual floodplain rehabilitation plans can be used to support a variety of projects that address connectivity, including stream and floodplain restoration projects, bridge and culvert replacements, road design, trail design and construction, and overall river corridor protection. For the Blue Mountain neighborhood, public work sessions will including land use planning to develop strategies that may provide community connectivity to the river, and develop public access to the river and a recreation amenity, while incorporating resilient river restoration strategies compatible with the ecological functions of the riparian corridor and floodplain. The 5-acre property adjacent to the crossing is jointly owned by all of the residents in the area through its road association. Prior to the flood, the road association had leased the land at a minimal cost to the Lyons Fire Protection District to house Fire Station #2, serving the rural residents in this area. After the station was destroyed in the 2013 flood, the LFPD determined it was best to move its #2 station and rebuild across the river (on the south side). This 5-acre lot, currently blighted by the flood, is ripe for improvements that offers the residents light recreational activities such as picnic and walks along the river. Simlar opportunties for public access to the river will be investigated in the Berthoud neighborhood, although there is currently no public access in this section. E. FEASIBILITY 19

The LTWRC is also applying for a CDBG-DR Capacity Building grant to hire a Watershed Coordinator and Program Assistant who will have direct responsibility for oversight, tracking and management of this project. The Fiscal Agent for this project will be Coalitions & Collaboratives, Inc (COCO INC). COCO INC is a new umbrella organization created by the Coalition for the Upper South Platte (CUSP), a nationally recognized nonprofit doing watershed, forest, and fire/flood emergency response work. COCO INC will provide an umbrella organization that encourages and supports new, emerging, and existing coalition and collaborative groups by building on a sustainable model and platform of leadership, infrastructure and organizational capacity. COCO INC will provide this support for groups seeking to protect and restore natural resources and local communities through the cooperative efforts of stakeholders, with emphasis on best available science, community values, and economic sustainability. CUSP s leadership staff (who bring decades of experience) will provide the management of COCO INC and provide management support for new and existing groups, such as the LTWRC. With COCO INC s support, the LTWRC will have immediate access to a variety of tools, such as online databases and GIS capacity, and will be able to use employee sharing to bring in expertise across the groups affiliated with COCO INC. Finally, COCO INC is under a group determination from the IRS, so organizations that come under its umbrella don t have to have their own 501(c)(3), but can be operated as an affiliate under our determination. Affiliates will also be able to be covered under a group insurance package, which includes policies for auto, D&O, worker s comp, crime, technology, volunteers, $2 million general liability, $5 million umbrella liability; and $1 million environmental. For this project, COCO INC will work directly with the Streering Committee of the LTWRC to hire and manage a a full-time watershed coordinator and assistant, who will be focused on implementing projects developed through the postflood planning process, and COCO INC will provide oversight management of grants, agreements, contracts, payroll, and associated reporting. #23 Describe how your plan, study or analysis addresses is cost effective and reasonable. Describe how you arrived at the project cost (12,000 character limit) Project costs were based on costs incurred and projected from previous studies, specifically the Master Plan. Costs were projected using standard hourly rates for engineering and outreach considered to be appropriate for the region. It is our feeling that the proposed budget is reasonable for the scope of work requested. 21

22 It should be noted that staff and volunteer time associated with this project was not included in the estimated project cost. These contributions, for example from LTWRC volunteers and staff for project management and coordination, or for landowner time to participate in the work sessions, were not calculated as part of the project budget. However, the value of these contributions is significant, totaling hundreds of hours over the life of the project. 24. Please provide a proposed project timeline with key milestones and demonstrate your ability to carry out the plan, study, or analysis in a timely manner, including your readiness to begin work immediately and complete work within 18 months. (12,000 character limit) The LTWRC is ready to start spending funds immediately after mutual execution of the contract with the State, and it is estimated that this project will require 18 months to complete. If a grant for this project is awarded, project implementation will be the responsibility of the LTWRC and its subcontractors. Following notification of the grant award and successful contracting, a Request for Proposal (RFP) will be distributed. Consultants will be engaged to implement the defined Scope of Work (see Question #8 in this application). The consulting team will be charged with all mapping, conceptual planning, and stakeholder engagement, with supervision and participation by staff from the LTWRC. The LTWRC and its staff will have the experience and capacity to manage this scale of project, as evidenced by their recent completion of the master plan for this region, on time and on budget. The proposed Project Implementation Schedule is below. 22
