Climate Change Considerations. The project will not induce more traffic, add travel lanes, or increase the roadway capacity of Interstate 87. The project will not change the long-term capacity of the stretch of SR 87 that is within the project limits. Therefore, the project is not expected to increase operational levels of greenhouse gas (GHG) emissions. Caltrans used the Roadway Construction Emissions Model (RCEM), provided by the Sacramento Metropolitan Air Quality District, to estimate that the preferred alternative for the project will result in the emission of 1,162.07 tons of carbon dioxide during construction (see Attachment U for details of the analysis). Because construction activities are short term, the GHG emissions resulting from construction activities will not result in long-term adverse effects. Implementation of the Caltrans Standard Specifications, such as complying with the air pollution control rules, regulations, ordinances, and statutes that apply to work performed under the contract, and the use of construction Best Management Practices (BMPs) will reduce GHG emissions from construction activities. The construction BMPs may include (but will not be limited to) the following: Perform regular vehicle and equipment maintenance. Limit the idling of vehicles and equipment on-site. If practicable, recycle nonhazardous waste and excess material; if such recycling is not practicable, dispose of nonhazardous waste and excess material properly. Use solar-powered signal boards, if feasible. Broadband and advanced technologies are not applicable to the project. Permanent erosion control measures will be implemented for the project to stabilize disturbed areas. These measures will ensure that these areas do not pose more risk of sediment discharge than they did before the commencement of construction activity and that there is no potential for construction-related stormwater pollutants to be discharged into the site runoff. Detailed erosion control plans and estimates will be developed during the PS&E phase. Given the disturbed soil area (DSA) for the project, it is estimated that the erosion control work will cost $400,000. Caltrans policy is to replace highway planting that is damaged or removed by State highway construction activities. Within and near the project limits, PM 0.0 to PM 0.74 and PM 4.85 to PM 6.28 are designated as having Classified Landscaped Freeway status. Therefore, the landscaping within these areas should be protected from construction and staging activi...
Climate Change Considerations. Greenhouse gas (GHG) emissions analysis determined that the project is qualitative (see California Executive Order B-30-15) and does not require use of the Federal Highway Administration’s (FHWA) Infrastructure Carbon Estimator tool to calculate GHG emissions. The scope and nature of the proposed project are relatively minor. The project is not expected to create additional roadway capacity, so it is not expected to result in increased operational emissions of GHGs. Although the project would generate construction emissions of GHGs, the GHG emissions would be short term. Construction emissions are unavoidable, but they will be reduced to the extent practicable through planning and implementation of best practices during the project delivery process. The following items are appropriate or applicable to the project: • Use of energy-efficient construction methodologies • Use of water-efficient construction methodologies • Use of fuel-efficient measures for both construction equipment and traffic management during delays or detours • Use of locally available building materials to reduce GHG emissions The proposed improvements for the project will not impact the accommodation of wired broadband facilities, fueling opportunities for zero-emission vehicles, or provisions for infrastructure-to-vehicle communications for transitional or full autonomous vehicles. Although maintenance work will be necessary after project completion, it is not anticipated that the maintenance workers will be exposed to high-speed traffic. This project does not modify or require new maintenance or freeway agreements.
Climate Change Considerations. Sea level adaptation measures are not needed for the project because the area is not vulnerable to sea level rise. The elevation of the project is approximately 80 feet above mean sea level. The bridge is inland approximately 4 miles and tsunami models only predict inundation in that region to potentially extend only about 1 mile in from the coast line. Compost applied to the roadside increases the rate at which carbon dioxide is removed from the atmosphere and converted to plant material and soil organic matter. The net greenhouse gas benefit from applying compost to the roadside can be calculated by using the compost calculator developed by the California Air Resources Board. Additionally, proposed tree planting will also reduce greenhouse gases if desired by the City. Caltrans may provide partnering opportunities in planned transportation projects with Wired Broadband Stakeholders to incorporate wired broadband within the State highway right of way. Broadband stakeholders have not contacted Caltrans regarding installing conduits for wired broadband within the project limits. Asphalt grindings can be incorporated into shoulder backing in approved locations (away from waterways) or recycled at an asphalt plant. The contractor is encouraged to recycle any reusable materials such as steel from guardrail, bridge railing, aluminum from signs, and asphalt grindings.
Climate Change Considerations. There are no climate change issues for the project. Reducing greenhouse gas emissions is only one part of an approach to addressing climate change. The proposed project is outside the coastal zone and not in an area subject to sea-level rise. Accordingly, direct impacts on transportation facilities due to projected sea-level rise are not expected.
Climate Change Considerations. Greenhouse Gas (GHG) emission analysis has determined this project to be qualitative and will not require implementation of the Federal Highway Administration Infrastructure Carbon Estimator tool to calcu- late GHG emissions. However, strategies to reduce GHG emissions will be considered to comply with the climate change requirements under Executive Order B-30-15. This project is not expected to result in increased operational emissions as no additional roadway capacity will be added. Construction emis- sions are unavoidable but will be reduced to the extent possible through planning and implementation of best practices throughout the project delivery process. Qualitative strategies for reducing GHG emissions, if appropriate, in- clude reduction of roadway construction waste, applying fuel efficient measures both for construction equipment and traffic management during delays or detours, using energy and water efficient construction methodologies, and recommending that material within a local radius of the project area and/or locally available building material be uti- lized.

Climate Change Considerations. Regardless of a Wild Xxxxx Xxxxx Only patch’s priority level, added considerations need to be given to those locations where Xxxxx Xxxxx have a lower vulnerability to the effects of climate change because their populations are less likely to disappear under various climate change scenarios (Xxxxxx et al. 2014). While the data layer does not cover the entire Chesapeake Bay watershed, the Xxxxx Xxxxx Integrated Spatial Data and Tools website has a GIS data layer (Xxxxx Xxxxx Patch Vulnerability) that identifies Wild Xxxxx Xxxxx patches with low exposure (predicted change in water temperature per unit increase in air temperature) and sensitivity (predicted frequency, magnitude, and duration of water temperature averaged over a range of temperatures). Groundwater exchange may also mitigate stream thermal sensitivity to air temperature change (Xxxxxx et al. in press), and spatial models are needed to predict the role of groundwater for Xxxxx Xxxxx spawning, feeding, and refugia across stream networks. Downstream Strategies has incorporated a climate change assessment into the Chesapeake Bay Xxxxx Xxxxx BRT Model it is developing that quantifies potential changes in the probability of Xxxxx Xxxxx presence that may result from a projected future climate scenario (Xxxxx Xxxxxxxxxx, personal communication). It should be noted that these are “generalized” projections since broad scale modeling is being performed and the predictor variables being used are annual (precipitation) or seasonal (stream temperatures). Therefore, the impacts of local extremes to climate (drought, flood) may have impacts on Xxxxx Xxxxx populations that are beyond the scope of the model. Future air temperature projections were obtained from the regional downscaled climate model ECHAM5 described by Xxxxxxxxx et al. (2011). All projections are based on the A2 scenario described in the Intergovernmental Panel on Climate Change AR4 report (IPCC 2007). Predictions of the probability of Xxxxx Xxxxx presence under this future scenario were made and then compared to the model’s original outputs. Under this future scenario, decreases in the probability of Xxxxx Xxxxx presence are due mainly to increased temperatures, while increases occurred when increased precipitation moderates the impacts of increased temperatures. Appendix Table VI summarizes at the HUC 8 level, the percentage of catchments that have a decreased probability of Xxxxx Xxxxx presence under the ECHAM5 A2 2042 climate scenario. Protect...
Climate Change Considerations. There is no anticipated Operational increase in Greenhouse Gas (GHG) Emissions for this project. The Construction GHG was calculated using the Caltrans Construction Emissions (CAL-CET) 2018 analysis tool. The Construction GHG emissions for CO2e will be 1,600 US tons.
Climate Change Considerations. All future stewardship plans for the Covenant must include consideration of the impacts of climate change and plan for adaptation and mitigation efforts to preserve and protect the ecological values of the land.
Climate Change Considerations. The Concessionaire acknowledges that the Grantor and the Department of Conservation are reviewing their obligations under the Climate Change Response Act 2002 and developing responses to address greenhouse gas emissions from activities conducted on public conservation land and waters. The reviews are likely to result in policies which seek to measure, manage and reduce greenhouse gas emissions from Concession Activities. The Grantor wishes to signal to the Concessionaire that new concession conditions related to both climate change mitigation and adaptation may be imposed during the life of this Concession to address greenhouse gas emissions associated with the Concession Activity.
