cultural preservation requirements often come into play when certain key actions are taken. these actions trigger the need for archaeological assessments:

• permitting: many engineering projects require permits that include cultural resource reviews to ensure construction does not disrupt historically significant areas. lina’s early involvement helps us integrate these reviews seamlessly into our project schedules, minimizing delays.
• funding: federal and state funding often requires cultural assessments as part of compliance with regulations like section 106 of the national historic preservation act (nhpa). section 106 mandates that any federally funded or permitted project evaluate potential impacts on historic properties, ensuring that development doesn’t erase traces of history.
• national environmental policy act (nepa): projects subject to nepa require environmental reviews, which often include archaeological assessments to evaluate their potential impact on cultural resources. lina’s experience helps us meet these requirements efficiently, whether the project involves state or federal land.
• 世界杯足球比赛预选赛 land use: projects on 世界杯足球比赛预选赛 lands must adhere to regulations that protect cultural resources. whether it’s a federal park or a state-owned parcel, thorough archaeological surveys are required to preserve the site’s historical significance.

streamlining section 106 compliance

at snyder & associates, lina collaborates closely with our project managers to ensure compliance with section 106 regulations. these regulations require thorough consideration of any potential impacts on historically significant properties before projects can move forward. by having an archaeologist like lina on staff, we ensure this process is integrated into the overall project timeline.

this proactive approach allows us to communicate efficiently with state historical preservation office (shpos), tribal historic preservation offices (thpos), and other stakeholders to assess and mitigate any adverse effects on cultural resources. as a result, projects proceed smoothly without unnecessary delays, and clients receive clear guidance on meeting regulatory requirements.

archaeology’s role in ensuring project success

archaeology plays a pivotal role in ensuring that projects do not inadvertently erase traces of our collective history. whether it’s an artifact or a structure of historical significance, archaeological assessments help preserve cultural landmarks for future generations. lina’s role ensures that these discoveries are handled appropriately, helping clients maintain compliance with laws and regulations while promoting cultural preservation.

while the sackett v. epa supreme court decision has forced the u.s. environmental protection agency (epa) and the u.s. army corps of engineers (usace) to revise their definition of waters of the u.s. (wotus), it will be business as usual for the environmental scientists at snyder & associates when completing wetland and stream delineations for our clients. the historic ruling decided that the clean water act (cwa) jurisdiction is limited to adjacent wetlands with a “continuous surface connection” to waterbodies recognized as waters of the united states. this narrower definition could make it more challenging to determine where a waterway ends and a wetland begins.

jeff walters, pws, and environmental sciences group leader at snyder & associates concedes, “the new wotus definition will certainly change the jurisdiction of specific wetlands without connectivity to relatively permanent waterways. however, our team still needs to complete environmental due diligence for our clients to ensure their projects are within the limits of the redefined law.” walters continues, “we complete wetland and stream delineations to provide baseline data to our clients and the u.s. army corps of engineers for their jurisdictional determination. understanding and interpreting the new rule is important because it formulates our opinion of jurisdiction when we write our reports, influencing the usace.”

through communications with several usace districts, nichoel church, pws, and environmental scientist with snyder & associates relays that “our contacts have consistently stated that while there will indeed be some changes to wotus jurisdiction, the usace still needs to receive and review delineations. this is important since the usace, in concert with the epa, provides jurisdictional determinations and permitting of projects with temporary and permanent wotus impacts.” church adds, “it’s not the responsibility of consultants or contractors to determine if potential wotus is jurisdictional. this responsibility still resides with the usace, and any impacts to wotus without a 404 permit will continue to result in applicants receiving cease and desist letters with possible enforcement penalties such as wotus restoration and fines.”

importance of wetland and stream delineations

in addition to informing the usace and clients, wetland and stream delineations provide baseline data for project managers to understand where wotus may be located within a project’s limits. this information is critical to understand so potential wotus impacts can be avoided or minimized. in a wetland delineation report, our environmental professionals document all wetland and stream features within a project area and provide an opinion on the jurisdiction of delineated features. ultimately, the usace regulatory branch determines jurisdiction using our wetland delineation report. usace also acts as the permitting agency that administers section 10 and section 404 of the cwa.

court decision impacts to permitting & determinations

at the crux of the sackett decision, the supreme court decided that a “significant nexus” is no longer a valid factor for determining wetland jurisdiction. significant nexus is the idea that a wetland must have a clear and substantial connection to larger bodies of water, like rivers and lakes, to fall under federal jurisdiction. previously, usace had to assess whether a waterbody significantly impacted the physical, chemical, or biological condition of traditional navigable waters to use this criterion.

now, the jurisdiction of the clean water act is limited to adjacent wetlands that are physically connected to other bodies of water on a relatively permanent basis. however, the exact meanings of “relatively permanent” and “adjacent” still need to be clarified by the epa and usace. until these definitions are established, and the updated wotus guidelines are officially published, there could be delays in obtaining permits and jurisdictional determinations. this means that now, more than ever, it’s crucial to consult with a trusted professional in the field before embarking on a project that might impact an affected waterway.

our environmental experts are here to help you take proactive steps to protect your projects and the environment.

client protection & satisfaction remains guiding principle

both walters and church confirmed that the usace is still accepting approved jurisdictional requests and permit applications; however, some of the submittals could be delayed as usace and the epa provide new definitions and guidance based on the sackett case. walters added, “in 20-plus years of completing wetland and stream delineations, i have worked through many supreme court rulings like sackett, including swancc v. usace and rapanos v. united states.

while the wotus definitions and interpretations have varied from case to case, our foundational goals have remained the same — complete the necessary delineation documentation to assist and protect our clients while maintaining our strong relationship with the usace.” before embarking on any project that could affect waterways, we urge you to consult with trusted experts who can provide guidance. at snyder & associates, we are committed to providing environmental due diligence and comprehensive wetland and stream delineations. we have a long history of navigating evolving regulations and are here to ensure your projects move forward effectively and in compliance with the law. don’t hesitate to reach out and take proactive steps to protect your projects and the environment.

nutrient trading has emerged as a compelling solution to address the challenges posed by nutrient discharge into water sources. by incentivizing nutrient pollution reduction, nutrient trading fosters agricultural sustainability and opens new avenues for collaboration between farmers, regulators, and environmentalists. by staying at the forefront of emerging trends, the experts at snyder & associates can help explain the significance of nutrient trading, its environmental benefits, and the steps involved in setting up nutrient trading programs.

understanding the process of nutrient trading

understanding nutrient trading is crucial in the realm of environmental sustainability, particularly in the context of water quality management. nutrient trading is a market-based approach to reduce nutrient discharges, primarily nitrogen and phosphorus, into water bodies. the concept promotes the idea that entities, such as farmers, wastewater treatment plants, and third-party representatives, can engage in a mutually beneficial relationship. nutrient trading works like this: farmers implement best management practices such as covering crops, reducing tillage, and using proper fertilizer management to minimize nutrient runoff, earning credit for the reductions achieved. these credits can then be traded with others, typically treatment plants or third-party representatives, that face challenges in meeting nutrient discharge limitations. this innovative system promotes sustainable farming practices and provides cost-effective solutions for wastewater treatment, further reinforcing a collaborative and economically viable approach to environmental conservation.

permit limits & motivation for trading nutrients 

environmental permits act as the first line of defense against nutrient pollution. these permits, issued to point sources like wastewater treatment plants and industrial facilities, come with specific limits on nutrient discharges. the intention is clear: control and reduce the levels of nitrogen and phosphorus entering our water ecosystems. while these permit limits are crucial for regulatory compliance, they also set the stage for a dynamic and market-driven approach to environmental stewardship. under the nutrient trading standard, facilities that successfully reduce their nutrient discharges below their permit limits can generate excess credits. these credits become valuable commodities that can be traded with others facing challenges in meeting their permit limits. it’s a win-win situation — environmentally responsible facilities benefit economically, while those struggling with compliance find a cost-effective path to meet regulatory requirements.

setting up nutrient trading programs

establishing a nutrient trading program involves collaboration between a city or wastewater treatment plant, regulatory bodies like the iowa dnr, and organizations specializing in nutrient trading. for example, iowa’s soil and water outcomes fund liaises between cities and local farmers, facilitating agreements and verifying nutrient reductions. the first step is to define clear permit limits for nutrient discharges, delineating the boundaries within which industries and wastewater treatment plants must operate. concurrently, a nutrient trading program must be developed, outlining the rules and mechanisms for buying and selling nutrient credits. this includes determining how credits are initially allocated, often based on historical discharges and regulatory benchmarks. the system must incorporate monitoring and reporting mechanisms, as well, to track nutrient discharges accurately. regulatory oversight plays a critical role in maintaining the integrity of the trading system, ensuring that environmental goals are met and water quality standards are upheld.

cost-effectiveness & comparisons: nutrient trading vs. infrastructure development

an intriguing aspect of nutrient trading is its cost-effectiveness compared to traditional wastewater treatment options. a case study conducted by our experts revealed that a small town could achieve significant nutrient reduction at a much lower operational cost through nutrient trading than through expensive treatment plant upgrades. reducing nutrients at a wastewater treatment plant often requires costly and intensive treatment equipment, leading to high capital expenses. rather than investing extensively in such infrastructure, which can be financially burdensome for a city, especially considering the marginal reduction in nutrient levels per liter, a more practical alternative is exploring nutrient trading.

challenges & limitations of nutrient trading

while nutrient trading offers numerous benefits, some challenges can occur. one significant hurdle is the accurate measurement and verification of nutrient discharges, as the success of trading relies on precise data. they ensure transparency and prevent fraudulent activities in the trading market, demanding robust monitoring and reporting mechanisms and posing a technological and logistical challenge. additionally, establishing fair and equitable allocation methods for initial nutrient credits can be complex, as historical discharges and baseline calculations may not capture evolving environmental conditions. the effectiveness of nutrient trading hinges on active participation, necessitating stakeholder engagement and regulatory coordination, which can be time-consuming and challenging to orchestrate. addressing disparities in the capacity of different entities to participate in trading, particularly small businesses, may pose equity concerns. striking the right balance between economic interests and environmental protection is another ongoing challenge, as the program must incentivize reductions in nutrient discharges without compromising water quality goals.

despite these challenges, a well-designed and carefully managed nutrient trading program has the potential to offer innovative solutions to nutrient pollution while promoting economic efficiency and sustainability. this topic remains a promising and sustainable approach to addressing nutrient-related environmental issues. by fostering collaboration between cities, regulatory bodies, and farmers, nutrient trading provides a cost-effective alternative for nutrient reduction and promises long-term benefits for water quality and environmental health. as communities explore solutions to meet nutrient reduction goals, the professionals at snyder & associates can help guide this process and show how nutrient trading can be a viable and environmentally conscious option.

uncontrolled stormwater runoff is a significant factor in the degradation of surface water quality and can lead to costly overflows that result in flooding and dangerous 世界杯足球比赛预选赛 health hazards. as urban development continues to surge, so do these associated issues. to address this growing problem, innovative strategies and technologies are being developed to both manage and monitor stormwater runoff more efficiently.

benefits of effective stormwater management

stormwater management is the 2022世界杯32强预选赛 , implementation, and maintenance of practices to control the changes in stormwater runoff caused by human actions. this operation is an essential part of environmental protection, as it helps to reduce the number of pollutants and sediment that can be carried away to local waterways. in the past, stormwater management was typically a secondary concern for municipal leaders, following water supply and wastewater management. in recent years, however, stormwater management efforts have grown as municipalities recognize the need and benefits of institutional stormwater programs. regulatory requirements often drive investments to deal with combined sewer overflows, pollution, flooding, and erosion in local streams and rivers. urban water planners hope to benefit from integrating management across water sectors for other municipalities. stormwater management is here to stay; no matter the driving cause, the snyder & associates team is here to help.

stormwater management in the transportation sector

stormwater management in transportation is especially vital in collecting and cleaning runoff. while streets, roads, and highways provide essential benefits in transporting goods, people, and services, they can become conduits for delivering pollutants into the water system. runoff from these surfaces can carry everything from heavy metals from car tires, brakes, and engine wear to hydrocarbons from engine lubricating fluids. if poor stormwater management practices exist, these pollutants can enter the aquatic environment and degrade the ecosystem. engineering design is key in diminishing these effects, with specific strategies tailored by location or project to incorporate best management practices (bmps). one of our stormwater experts, steve klocke, p.e., detailed several of our team’s most common practices and design strategies for transportation-related stormwater projects.

bioretention cells
a bioretention cell is a filtration or infiltration basin that uses vegetation, soils, and other natural materials to remove pollutants from stormwater runoff. these systems are an effective and attractive way to manage stormwater runoff that can be used in developed and undeveloped areas. there are many benefits to using bioretention cells, including improved water quality, reduced runoff, and improved aesthetics. however, one downfall of this practice is that routine maintenance is required to manage vegetation and clean debris from the cells. if proper action is not taken, backups can occur, resulting in an ineffective system.

the fourmile wetland was created to help removed stormwater from polk county’s largest watershed spanning 76,600 acres.

constructed stormwater wetlands
a constructed stormwater wetland is an engineered system capable of removing sediment, nutrients, and other pollutants from larger volumes of water while also providing stormwater detention. this stormwater management option offers a variety of benefits, including reducing flooding, improving water quality, and providing habitat for wildlife. as a manmade feature, constructed stormwater wetlands are created by excavating a basin with a mixture of shallow areas and deeper pools and planting native wetland plants. the basin is fed by a stormwater pipe or a natural waterway like a stream or creek. as concentrated stormwater rushes into the wetland, it spreads out, and the velocity drops as it slowly meanders its way through the wetland, allowing sediment to settle out and plants to filter out pollutants. during large storm events, the wetland provides temporary detention and storage for floodwater.

initial upkeep for these systems is focused on establishing the wetland vegetation for the first few years. future maintenance activities involve mowing side slopes several times a year, removing invasive species, monitoring sediment accumulation in the forebay and normal pool areas, and removing sediment as required. it is important to remain consistent in the upkeep of stormwater wetlands as an unmaintained constructed wetland may become an eyesore and nuisance to the community. with extreme neglect, a constructed wetland may stop filtering the rainwater entirely. this could allow trash and pollutants to enter local streams, causing flooding or safety concerns — and repair expenses may far exceed the cost of regular maintenance.

stormwater detention vaults were in place during jasper street construction in pleasantville, iowa.

detention vaults
providing stormwater detention for roadway runoff can be challenging, especially in an urban setting where right-of-way and utilities limit the available space. the most economical approach for stormwater detention is to acquire land adjacent to the roadway. when that option is not possible or practical, underground detention vaults may be utilized. various underground detention vaults (or chambers) are available, ranging from a single concrete box or a series of pipes to manufactured concrete chambers or modular plastic units. these structures can store large amounts of stormwater and slowly release it after the rain has passed, preventing uncontrolled runoff and protecting our waterways and infrastructure.

permeable paving
permeable paving is an increasingly popular choice for both residential and commercial applications. this type of paving allows water to pass through its surface, making it an ideal solution for parking lots, alleys, and low-volume roadways, as it will enable stormwater to be captured and treated while still allowing traffic flow. permeable pavers are widely used and available in various styles, colors, and performance levels. a porous asphalt pavement and permeable concrete are viable options in the appropriate setting. these pavements provide numerous benefits, including improved drainage, reduced runoff, groundwater recharge, and reduced ice and snow accumulation. although this can be a great alternative for parking lots, sidewalks, and driveways, permeable paving may require special considerations for use in high-traffic or high-speed areas as it can have a lower load-bearing capacity than conventional pavement types.

the parking lot of armstrong park is created of permeable pavers allowing stormwater to seep through.

mechanical separators
mechanical separators are a stormwater management technique typically used in urban areas to remove suspended sediments and trash, debris, and oil from stormwater. these include proprietary systems such as hydrodynamic or vortex separators, gravity separators, filtration systems, and simpler structures like storm intakes with a sump or insert to capture sediment. this option is particularly viable when space limitations prevent using other bmps as it is incorporated into a stormwater intake or located immediately adjacent to the intake. to treat the runoff, these systems put captured stormwater through screenings and churning to remove unwanted contaminants before releasing the cleaned stormwater. depending on the type and size of the structure, they can be costly and are typically used only in heavily urbanized areas where other practices are impractical.

selecting the right stormwater management system

every community is different, and every stormwater project has distinct needs. as a result, there is no one-size-fits-all solution when it comes to stormwater management. with so many different options on the market, it can be difficult to know where to start. our experts consider factors like available right-of-way space, current utilities in the area, desired level of treatment, and budget when determining which process or combination of processes would provide the best results. however, even with our years of practical knowledge and experience, all stormwater practices require some analysis or modeling to properly size and design. with this more precise data, our engineers can pinpoint capacity levels and provide the right-sized solutions to combat localized flooding and waterway degradation.

funding considerations drive project success

on the investment side, transportation stormwater management also requires thoughtful strategy. setting aside sufficient funding for stormwater management is key, as is finding ways to make up for funds if projects fall short of their financial goals. creative funding sources such as low-interest loans, grants, and credits can help finance these efforts while maintaining budgetary goals and deadlines. our team has decades of experience navigating the complex application process that often accompanies grant funding and may be able to help your community find the necessary funding to jumpstart your next project. ultimately, transportation stormwater management is a complex issue with multiple considerations. our civil engineers and transportation professionals continuously work to find innovative approaches to ensure that new construction and renovation projects have sustainability and stormwater infrastructure in mind.

the establishment of pedestrian-only streets is another significant development in pedestrian-oriented infrastructure. these car-free zones prioritize the needs and safety of pedestrians, allowing for uninterrupted walking and promoting a more enjoyable urban experience. pedestrian-only streets attract vibrant street life, with pedestrians freely exploring and engaging with their surroundings. they also provide opportunities for street vendors, performers, and other forms of 世界杯足球比赛预选赛 life that contribute to the vitality and character of the city.

we address several pressing issues by encouraging walking and cycling by providing pedestrian-oriented infrastructure. one of the primary benefits is the reduction of traffic congestion. as more people choose to walk or cycle for shorter trips, there is a corresponding decrease in the number of cars on the road. this reduction not only eases congestion but also leads to shorter travel times and fewer delays for those who rely on cars for transportation.

furthermore, prioritizing pedestrians contributes to improved air quality. with fewer vehicles emitting pollutants, cities experience a significant reduction in air pollution levels, leading to healthier environments for residents. this improvement in air quality directly impacts 世界杯足球比赛预选赛 health, reducing the risk of respiratory problems and other pollution-related illnesses. promoting pedestrian-oriented infrastructure also encourages healthier lifestyles. walking and cycling are forms of physical activity contributing to overall fitness and well-being. by designing more walkable and bike-friendly cities, individuals are more likely to incorporate active transportation into their daily routines, increasing physical activity levels and improving health outcomes.

embracing complete streets for a sustainable future

the concept of complete streets is revolutionizing urban 2022世界杯32强预选赛 by designing roads and streets that accommodate all modes of transportation, including pedestrians, cyclists, and 世界杯足球比赛预选赛 transit. complete streets feature dedicated bike lanes, crosswalks, and 世界杯足球比赛预选赛 transit stops, ensuring safe and efficient movement for all users. this trend aims to reduce reliance on private vehicles and foster a more inclusive and sustainable transportation network.

one of the key elements of complete streets is the provision of dedicated infrastructure for various modes of transportation. this includes incorporating bike lanes, which offer safe spaces for cyclists to travel alongside motor vehicle traffic. these lanes can be physically separated from the main roadways, creating a barrier between cyclists and cars, or they can be marked with designated signage and pavement markings to enhance visibility and promote a shared space between cyclists and motorists. by integrating bike lanes into the street design, complete streets encourage cycling as a viable alternative to driving, reducing congestion and emissions and promoting physical activity.

another crucial aspect of complete streets is the inclusion of well-designed crosswalks and pedestrian facilities. pedestrians are often the most vulnerable road users and complete streets prioritize their safety by providing marked and accessible crosswalks, sidewalks, and curb ramps. sidewalks may be widened or added where lacking, ensuring pedestrians have safe and comfortable spaces to walk and interact with their surroundings. other pedestrian-friendly features such as countdown timers, raised crosswalks, and pedestrian refuge islands contribute to safer and more convenient journeys.

moreover, complete streets emphasize the integration of 世界杯足球比赛预选赛 transit infrastructure. this involves designing streets to accommodate bus stops, transit shelters, and dedicated lanes for buses or trams, facilitating efficient and reliable 世界杯足球比赛预选赛 transportation services. by prioritizing 世界杯足球比赛预选赛 transit, complete streets aims to make it a more attractive option for commuters, reducing the reliance on private vehicles and decreasing traffic congestion and air pollution. integrating 世界杯足球比赛预选赛 transit into street design also promotes equitable access to transportation, ensuring that individuals without access to private vehicles can still navigate the urban environment effectively.

incorporating “complete streets” into infrastructure improvement projects
the overarching goal of complete streets is to create a sustainable, inclusive transportation network that supports various modes of travel. by prioritizing the needs of pedestrians, cyclists, and 世界杯足球比赛预选赛 transit users, complete streets promote active and healthy lifestyles, reduce greenhouse gas emissions, and enhance overall city livability. additionally, these street designs often improve economic vitality by creating more inviting business environments and fostering vibrant street life. to implement complete streets effectively, collaboration among various stakeholders is crucial. this includes input from transportation planners, urban designers, 世界杯足球比赛预选赛 health officials, community members, and advocacy groups. by working together, cities can adopt comprehensive policies, guidelines, and design standards that prioritize complete street principles in future development projects and retrofit existing roadways.

a massive storm causes a 100-year flood. the term “100-year” simplifies a flood that has just a 1% chance of occurring in a single year. mistakenly, many assume that experiencing such a flood means they are safe for the next 99 years. the probability of a 100-year flood remains constant at 1% each year. without preparation, these rainfall events can be devastating to a community. however, effective stormwater management and 2022世界杯32强预选赛 can mitigate the potential damage. in times of significant flooding, the flat areas adjacent to a river’s edges, referred to as the floodplain, play a crucial role. they act as a natural space that slows down and spreads dangerous floodwaters.

this process prevents the waters from inundating communities along the riverbanks, thereby preventing harm to people and property.  when properly handled, floodplains offer a wide array of advantages to both human society and the environment. these benefits range from shielding against floods to preserving water quality and providing habitats for wildlife. to ensure that floodplains remain resilient in the long term and that nearby developments are well-protected, the snyder & associates team dedicates their efforts to identifying and resolving potential concerns during the early stages of project development.

creating functional designs in a floodplain

snyder & associates studied the fourmile creek watershed to update the floodplain model, replacing outdated fema maps.

rivers and streams are continuously meandering and changing paths. setting aside room for this movement and the passage of significant flood events is a community’s best protection against flood damage. it is one of the most substantial routes to maintain an adequate floodplain. however, these areas are often in high demand for development. assessing flood risk and 2022世界杯32强预选赛 for functional floodplains requires a comprehensive understanding of the factors contributing to high water events. working with professionals like our environmental scientists and stormwater engineers can give businesses and communities the expertise to reduce susceptibility to future flood damage.

when dealing with projects in floodplains, the initial focus is on the project’s location in the floodway. although development within a floodway is feasible, it is intricate due to the requirement of not increasing water surface elevation during a 100-year storm event (base flood elevation or bfe). this entails navigating a time-consuming and expensive process with fema. understanding the development’s position relative to historical flood data and modeling guides us in assessing risk and determining the necessary permits.

for any floodplain development, any structure (including its basement) must be elevated at least one foot above the bfe – a standard that often necessitates more significant elevation in certain jurisdictions. this guideline is established to minimize flood-related damage and lower flood insurance premiums. furthermore, adhering to building codes mandates elevating mechanical and electrical systems to or above the bfe, and any construction materials used below the bfe must be flood damage resistant. while compliance with building codes ensures the safety of occupants, it might fall short in securing a facility’s sustained functionality post-flood. when devising plans for a facility located in a flood-prone area, our focus is on creating a design that fulfills permitting and code requirements while ensuring long-term viability in that location.

performance-based design approach

historically, building codes took a prescriptive approach, limiting options for compliance and hindering innovation. in contrast, our specialists adopt a performance-based design approach. this method evaluates how the entire building system, encompassing both landscaping and the actual structure, is expected to perform under conditions associated with potential hazards. from the outset of design discussions, we guide project decisions to ensure a resilient design aligned with city, state, and federal codes. in certain regions, the flood risk is deemed too significant for development. community green spaces, localized detention basins, and stormwater wetlands emerge as favorable alternatives. these spaces are purposefully designed to withstand flood events with minimal damage during substantial storms.

our team demonstrated this concept on the east side of des moines through the easton boulevard detention basin. this previously flood-prone area near leetown creekway was transformed into a stormwater detention basin with added park amenities like recreation trails, landscaping, benches, and lighting surrounding the basin. this basin now safeguards against up to 100-year storm events, boasting a maximum storage capacity of approximately 94.5 acre-feet while serving as a community greenspace for nearby neighborhoods. collaborating with floodplain assessment and 2022世界杯32强预选赛 experts allows communities to envision the potential within these seemingly challenging landscapes. while 2022世界杯32强预选赛 marks a crucial starting point, the subsequent development phase grapples with the intricate task of satisfying federal and local permitting regulations.

the role of 世界杯足球比赛预选赛 policy in floodplain development

council bluffs has initiated ten projects to recertify its entire levee system before the 2023 fema assessment. this is to protect residents from flooding and potentially higher insurance costs.

the federal emergency management agency’s (fema) national flood insurance program primarily determines how floodplains are developed. fema maintains an ongoing collection of flood maps that undergo updates to account for climate changes, like increased rainfall and intensified storms, as well as improved modeling methods and recent developments. these flood maps assist mortgage lenders in determining insurance necessities and empower communities to devise approaches for minimizing their risk.

however, while fema establishes a foundational framework for floodplain management, local governing bodies may impose extra or more stringent regulations regarding floodplain development. numerous states and communities throughout the country are enhancing flood mitigation cost-effectiveness by using regulations to steer development away from high-risk zones. in tandem, they are creating policies that optimize the returns on modest upfront government investments. stakeholder engagement is critical in a community’s policy decisions for flood prevention and mitigation efforts.

by engaging stakeholders, organizations can increase awareness of flood risks, facilitate collaboration and coordination, tap into local knowledge and expertise, implement effective strategies, and improve communication with the local community. by working together, stakeholders can help communities make informed decisions when adding development in the floodplain.

harnessing the power of the natural environment 

floodplains constitute a vital component of robust river systems that have been altered through levees, dikes, and other construction. while development often becomes necessary, it does not inherently have to harm the surrounding ecosystems. our team’s commitment to identifying and addressing floodplain issues at the outset of projects guarantees a harmonious coexistence between communities and floodplains. we recognize that the vitality of a floodplain extends beyond disaster prevention — it encompasses fostering a flourishing, equilibrium-rich ecosystem that enhances the well-being of everyone. contact our professionals today and let us help you explore ways to devise intelligent designs within your floodplain areas.

maintaining a safe and reliable transportation system is essential for any city or town, and the quality of a community’s streets and infrastructure has a significant impact on its livability, economic vitality, and overall quality of life. however, over time, aging infrastructure can deteriorate, and roadways can become damaged, leading to a decline in driving conditions, accessibility, and safety. when it comes to improving roadways, there are several reconstruction methods and improvement options to consider, each with its advantages and disadvantages. the comprehensive design services offered by the snyder & associates team ensure we can cover any option your specific situation requires. here, we’ll explore several roadway reconstruction methods and improvement options guided by criteria such as the need to replace underground infrastructure, pavement rehabilitation options, adding multimodal accommodations, and adding or reducing lanes.

road reconstruction when underground infrastructure needs replacing

when underground infrastructure such as water, sanitary, or storm sewer lines require repair or replacement, street reconstruction is often necessary. this process typically involves removing the existing pavement, excavating the roadway to access the underground infrastructure, making the necessary repairs or upgrades, and then rebuilding the roadway from the ground up. this approach ensures that the infrastructure below the surface is functioning properly and safely while also providing a new, smooth, and durable roadway for drivers. our team’s ability to “package” projects together can often save substantial amounts of money for our clients. our recent work in two locations around council bluffs showcases our ability to match the most cost-efficient repair or replacement option with each particular need.

pavement rehabilitation & reconstruction options

sometimes the underground infrastructure is in good condition, and the focus of the road improvement is on the pavement itself. two popular pavement reconstruction and rehabilitation options are crack and seat and full-depth reclamation (fdr). crack and seat is a process where the existing concrete pavement is fractured into small pieces using specialized equipment. the fractured pieces are then compacted to create a stable base for a new layer of pavement. this technique is best suited for pavements with moderate to severe cracking or unevenness and the base material is in good condition. the crack and seat method also eliminates the need (and expense) of hauling and disposing of broken chunks of the old roadway. read more about this unique roadway rehabilitation process performed along school street in the city of carlisle. full-depth reclamation (fdr) is a more comprehensive approach that involves pulverizing the existing asphalt or concrete pavement with a special milling machine and blending it with the underlying layers of soil and aggregate. emoluments are then added for stabilization, creating a new base layer that is then covered with a new layer of asphalt. fdr is best suited for pavements with deep structural issues, including rutting and base failures. click here to read a more in-depth discussion about fdr and how our team has incorporated this process into our service offering.

working with existing infrastructure to add multi-modal accommodations

pedestrian “refuge islands” make it safer for people to cross a street with busy traffic.

as communities seek to become more accessible, equitable, and sustainable, they’re consistently placing a greater emphasis on multimodal transportation options such as walking, biking, and 世界杯足球比赛预选赛 transit. one way to improve the safety and accessibility of roadways is to add multimodal accommodations. this may include adding bike lanes, sidewalks, or dedicated transit lanes. bike lanes provide a designated space for cyclists to ride, separating them from vehicular traffic and increasing safety. these lanes can be added to existing roadways by repurposing a portion of the roadway or by widening the road. sidewalks provide safe, accessible walkways for pedestrians, increasing connectivity and promoting active transportation. in areas where sidewalks are lacking, they can be added through new construction or by widening the roadway. dedicated transit lanes and floating bus islands provide a designated space for buses or other 世界杯足球比赛预选赛 transit vehicles, allowing them to bypass traffic and improving travel times for transit users. these lanes can be added by repurposing an existing lane or by widening the roadway. our team of experts has been instrumental in implementing all types of multi-modal accommodations for numerous clients and communities. these projects include the alburnett road corridor extension in the city of marion, pleasant hill streetscape upgrades, and the 6th avenue streetscape project for the city of des moines. all these projects incorporate one or more multi-modal features.

adding or reducing (road diet) roadway lanes

adding or reducing lanes is another option for improving the functionality and safety of streets. adding lanes can increase capacity and improve traffic flow while reducing lanes, also known as a “road diet,” can improve safety by reducing speeds and the number of conflict points. when considering adding or reducing lanes, it’s imperative to conduct a thorough traffic analysis to determine the impact on traffic flow and safety. it’s also important to consider the needs of all users of the street, including pedestrians and cyclists. while adding lanes may often require the installation of a new pavement area, a road diet is typically completed within the bounds of the existing roadway. dual-use center turn lanes may be added, as well as dedicated bike lanes to meet the multi-modal needs of the area. our team’s recent work along 5^th avenue s in fort dodge highlights the benefits of adding turn lanes to a busy commercial thoroughfare. further to the south, in knoxville, we completed a road diet project along lincoln street/iowa highway 14 that maximized the city’s investment and created a safer, more efficient corridor.

customized comprehensive street & roadway solutions

developing safe and reliable roadways is crucial for any community’s success. aging infrastructure and damaged roadways can negatively impact driving conditions, accessibility, and safety, ultimately affecting a community’s quality of life and economic vitality. fortunately, there are various roadway reconstruction methods and improvement options available, each with its benefits. the snyder & associates team offers comprehensive design services to help communities navigate these options and find the best solutions for their specific needs. by investing in the improvement of their transportation system, cities and towns can create a more livable and thriving environment for their residents and businesses.

when snyder & associates opened its doors in 1977, all drafting work for engineering projects was done with pencil, paper, and drafting triangles. however, as technology has evolved, so has our firm. with several design teams of over 40 technicians, we regularly use computer-aided design to develop plans in two- or three-dimensions so that our engineers and clients can better visualize every aspect of a project.

going back to the basics of cad

cad technician in 1989 as technology began to catch up with the software drafting concept.

the history of computer-aided design, more commonly known as cad, closely parallels the induction of the computer. with its creation in 1957, cad was still decades ahead of the technology and software readily available then. therefore, pencil and paper would remain the primary way engineering and architecture designs were drafted for another 30 years. however, the groundwork was set, and cad software would eventually become an essential tool within the engineering industry.

advantages cad brings to the aec industry

cad offers many advantages over its manual drawing predecessor, making it an essential tool in the architecture, engineering, and construction (aec) services industry. these advantages help our engineers and technicians in several ways, including increased efficiency, accuracy, and visualization.

efficiency
the main advantage of cad drawing is that it saves significant time. computers can perform actions quickly and accurately, so technicians can create components without the need for exacting measurements, as when completing a plan by hand. cad software is also malleable, easily edited, and provides access to functions such as copying, pasting, resizing, and other digital actions you can’t complete when 2022世界杯32强预选赛 on paper. this time savings translates directly into increased productivity and, in turn, cost savings that can be passed on to clients.

accuracy
due to the human element involved, manually created designs have a higher propensity for errors. cad nearly eliminates this risk as the software has features and tools that are directly developed per design and drawing conventions and standards. with interference checking and other features, our technicians can quickly inspect the drawing or element for critical design errors. even with these optimized features as checks and balances, cad technicians must be mindful of potential human or software errors. to remove this occurrence, the snyder & associates design team has established a reliable process for quality checks where one or more technicians will review the design and plans for final accuracy and overall standards.

visualization
before cad technology, hand-drawn designs had limited visualization impact. now, renderings can be used to quickly create realistic images, allowing engineers to receive client feedback before a project even begins. these renderings communicate the look of a design and how it fits into the built environment, how construction phases will occur, and even how traffic flows could be impacted throughout construction.

cad options utilized by our team

at snyder & associates, our cad designers work directly with project engineers to create models that are as comprehensive as possible using tools for digital design, 2d and 3d drafting, modeling, animation, rendering, construction, and more. we utilize three programs to create these various deliverables to ensure the information and formatting are suitable for each project.

autodesk
autodesk is an all-purpose drafting platform for 2d and 3d drawings. it was one of the original cad programs and still stands as one of the world’s most widely used drafting programs. autodesk is known across the industry as the most straightforward system to understand and operate due to its command-based and design-oriented approach. our team incorporates this program for most of our site development, commercial, and municipal projects due to its broad use among subcontractors and ability to transfer and share files. we take initial field survey data using autodesk and generate existing features as 2d and 3d models with 3d surfaces in an existing base file. this provides 3d-surfaced images that design technicians can use to lay out proposed design features in both dimensions. this base file and the design files help develop the construction drawings that will be reviewed, quality checked, and approved by the project engineer before being sent to the client for review.

microstation
like autodesk, microstation is used to design, draft, develop, and generate 2d/3d vector graphics and highly intelligent models conveying design intent. but that is where the similarities with autodesk end. microstation has a transportation-oriented focus with a more technical interface. for our transportation clients, microstation is widely used in the design of intersections, roads and highways, institutional work, and wind farm site development. when starting a project in microstation, our technicians receive a 3d-surfaced terrain image previously established by our survey staff. with that existing layout, they’ll structure a proposed horizontal alignment and vertical profile within the software. a roadway template is applied with these parameters in place, creating a digital project model. sections of this model can then be cut into visual sheets to make contractors’ plans. incidentally, the model is often delivered to the project contractor to “guide” grading and paving equipment during construction.

revit
our designers use revit software to build an intelligent 3d model with real-world information. it’s a specialized building information modeling (bim) software specifically intended for designing and structurally analyzing buildings. our structural engineering subsidiary, 2022足球世界杯小组赛赛程 , employs this system when creating documents for structural projects such as the ankeny kirkendall library and the polk county historical court house renovation. revit allows simplified collaboration between disciplines, including architectural, structural engineering, and mechanical engineering teams working on the same building or project. in most cases, before commencing a structural project in revit, the architect would have already progressed beyond the conceptual stage by creating a building model featuring generic walls, floors, and roofs. our specialists developed a separate revit model for the structural components, including preliminary framing, foundations, and structural floors. these models are then integrated with the architect and mechanical models to ensure effective coordination and clash detection.

live linking the various models through a cloud server or file transfer site allows constant coordination and immediate notification of changes during the project’s life. as the project hits certain milestones, the drawings get more defined to the point of the final completed construction documents available for contractors.

intentional design sets the snyder & associates team apart

poor understanding of plans can result in delays, cost overruns, or construction mistakes. in this industry, this can have disastrous consequences. our design teams pride themselves on delivering clear and detailed engineering plans.

our design technicians pride themselves on being known for detailed, concise, and easy-to-read designs.

our core differentiating quality is that we incorporate “intentional design” in every single project. when using any drafting programs, the software spits out values that might be mathematically correct but are not necessarily cost-effective for our clients. our team takes the extra step to refine the design to make “fiscal” sense from a construction and budget perspective. this intentional design effort may be considered old school to some firms, but this quality-ensuring process makes a snyder & associates-developed plan stand out.

in addition to eliminating mistakes, utilizing our detailed documents with clear and concise language can be a considerable asset in 世界杯足球比赛预选赛 engagement. renderings can often double as preliminary models to showcase what is to come for a community. when the 世界杯足球比赛预选赛 can see the outcome, they are often more forgiving during construction.

to put it simply, cad has been revolutionary for the aec industries. in some cases, it has merged the roles of drafters, designers, and engineers and has bridged the visionary gap between engineering firms and clients. as our firm grows, we are proud to continue building a team of cad technicians with extensive industry expertise and advanced technical capabilities that can successfully take your project ideas from initial design to final product.

parks not only provide a space for people to relax and connect with nature, but they also foster community spirit and promote physical activity. for many communities, however, dedicating increasingly limited open space to create new park areas is not a practical solution. with a full-service landscape architectural team, snyder & associates has been vocal in promoting the value of upgrading park amenities for existing park spaces. these park amenity upgrades can have a significant impact on the community, promote inclusivity, increase recreation choices, and overall, provide a more positive and fun experience for users.

all-inclusive playgrounds bring everyone onboard

approximately 13% of children in the united states are served by the individuals with disabilities education act (idea). yet, this broad segment of the population is often lacking when it comes to safe, sensory-appropriate playground facilities. while ada requirements call for accessible pathways to playground equipment, an appropriate ratio of ground-level play activities versus those higher up on the structure, and transfer platforms for children with mobility devices, inclusive playgrounds go a step further. these facilities are designed to be welcoming, engaging, and challenging for all children and provide opportunities to develop cognitive, sensory, physical, and social skills.

the specialized surface and numerous ramps at the ankeny inclusive playground make the structure fully accessible to all users.

all-inclusive playgrounds feature a variety of environments where children can engage at their own pace and sensory input level. they are also welcoming to parents and caregivers, many of whom may have a disability, as well. noteworthy aspects of these parks include custom-designed, rubberized coatings that provide a flat, cushioned surface, free of obstacles. using extensive ramp systems, these playgrounds can even include “two-story” play structures where individuals with mobility devices can access both stories of the equipment and enjoy unique views of the surrounding area.

in addition to ramps, sensory-rich play features and specialized swings are also added to provide a space for children to play together and provide the opportunity to teach children valuable lessons about diversity and empathy. our team has been instrumental in the 2022世界杯32强预选赛 , design, and installation of numerous all-inclusive playgrounds around the midwest, including the following:

all-inclusive playground & baseball field: ankeny miracle league

all-inclusive recreational opportunities: urbandale miracle league field & playground

ada-compliant ramps, walkways, paths, & trails

of course, making the entire park accessible to all is essential in promoting inclusivity. ada-compliant ramps, walkways, paths, and trails make it possible for people with mobility issues to move around easily and safely and enjoy all the amenities a park has to offer. this can include adding ramps to play structures, creating smooth paths through the park, and providing accessible picnic tables and benches. these upgrades not only benefit people with disabilities but also parents with strollers and older adults who may have difficulty navigating uneven terrain.

restroom buildings with local flair

the restroom building in pella’s kiwanis park mimics the aesthetic of local architecture.

ada-compliant restroom buildings are another essential amenity that should be included in any park upgrade project. one of the primary advantages is the convenience that it provides, especially for families with young children. adding a restroom structure also creates the opportunity to design a building that mimics local themes or landmarks that can enhance the aesthetic appeal of the park and provide a unique experience for visitors. this can also promote a sense of community and pride in the local area, as the park’s design reflects the history and culture of the region. overall, adding themed restroom buildings to local parks is a simple but effective way to improve the overall park experience for visitors while also contributing to the community’s cultural identity. our design work for pella’s kiwanis park is a prime example of putting this idea into action.

inclusive playground & park improvements for pella’s kiwanis park

open-air shelters and picnic areas create gathering spaces

open-air shelters and picnic areas are other essential park amenities that can be added to provide a space for people to gather and socialize. upgraded picnic areas can include shaded structures, bbq grills, and improved seating options. these shelters can also provide a space for community events and gatherings, like outdoor concerts or movie nights. explore how our team has developed numerous park plans that seamlessly incorporate open-air shelters to fit the park aesthetic without overwhelming the natural landscape.

low-maintenance landscaping and hardscaping

upgrading the landscaping and hardscaping can reduce maintenance costs and improve the park’s appearance. low-maintenance landscaping can include drought-tolerant plants and native grasses that require less water and fertilizer. hardscaping upgrades can include replacing gravel paths with concrete or pavers, reducing the need for regular maintenance, or permeable paving which allows rainwater to infiltrate the ground, reducing runoff and erosion. these upgrades can also make the park more attractive and inviting to visitors.

recreational options include adding pickleball & tennis courts

while tennis has long been a popular recreational option in community parks across the country, pickleball has rapidly expanded in popularity and surpassed tennis’ reign among recreation seekers. conveniently, however, both sports can share the same space, saving on development and maintenance expenses. popular upgrades that our team has developed for countless facilities include resurfacing courts, adding lights for night play, upgrading nets and complex fencing systems, providing spectator seating areas, and improving access walkways and paths. these upgrades can attract more players and promote healthy competition and physical activity.

recreational tennis & pickleball courts thriving in parks & school districts

skateparks gaining in popularity

the young’s park upgrades in knoxville included this custom-designed skatepark.

skateparks are another amenity that has been gaining in popularity, in both community parks and as standalone facilities. adding or upgrading a skatepark can provide a safe and fun space for skateboarders, rollerbladers, and bmx riders, and have the added benefit of attracting teens and young adults to the park. upgrades can include the addition of more features, like half-pipes and rails, and improving the quality of the concrete while new construction options are practically unlimited in their configurability, features, and size. our design team has developed plans for countless skateparks, ranging from small, community park venues, all the way up to one of the largest skateparks in the country.

the rapid and continual expansion of multi-use trails across the united states has opened a new world of recreation and exercise options. along with the trails, pedestrian bridges have experienced a comparable increase in the construction of unique, iconic, and picturesque structures to complete trail connections. spanning rivers, lakes, roadways, and valleys, these bridges are no longer simply utilitarian pieces of infrastructure that connect point a to point b. instead, the bridge often becomes its own destination.

many of these bridges have been designed by engineers to be both functional and visually appealing, with features such as arches, curves, and different colors and textures. some bridges are also built with artistic elements such as sculptures, ornaments, and lighting, adding to the overall aesthetic appeal. the trestle-to-trestle bridge in johnston, iowa is a prime example. this bridge has quickly become a major draw, not only for nearby residents in search of recreational opportunities but also for tourists who are drawn to the intricate light displays that illuminate the structure at night.

railroad bridges along abandoned stretches of track have also become incredibly popular as the rail-trail concept has taken off. giving these structures a second life as a trail bridge can greatly reduce expenses for the owner community when compared to building a new structure. the high trestle trail bridge between woodward and madrid, iowa highlights the impact of reusing a railroad bridge on a massive scale. this 2,530-foot-long, 130-foot-tall bridge over the des moines river was constructed on nearly two dozen existing concrete piers from a former railroad bridge. this structure not only draws recreational trail users but also has become a magnet for railroad and train buffs who enjoy viewing the repurposed structure.

some trail bridges draw visitors because they’re visually attractive, and they provide access to equally stunning scenery. the mark c. ackelson trail bridge in easter lake park checks both of those boxes. it seemed unlikely at first, but this pedestrian bridge has become a tourist attraction in its own right. people visiting the park make it a point to stroll across the bridge and catch the one-of-a-kind views over the restored wetlands. the entire span is well-lit and features several viewing outcrops along the way for people who need to rest periodically on the journey, take in the breathtaking landscape, or simply want to sit and watch other pedestrians go by.

improved access, economic boost & increased recreation

in providing connections across once-impassable spaces, bridges and trestles can address environmental and equitable access concerns in areas where people otherwise would need motorized transportation. at the same time, they can be critical in linking together larger networks of trails, which serve as major tourism draws and economic engines.

the construction of trail bridges creates jobs for the local community and increases economic activity by boosting local businesses. and as part of hiking and biking trails, they can provide access to parks, nature preserves, and other recreational areas. when strategically positioned, they’re often used as backdrops or gathering places for community events and festivals, providing a unique and memorable experience for participants.

snyder & associates trail bridge project sampling

trestle-to-trestle bridge

trestle-to-trestle trail bridge over beaver creek, johnston, iowa.

in the spring of 2019, the trestle-to-trestle trail bridge over beaver creek was severely damaged by an ice dam and collapsed. the former trail bridge was originally a 316’-long timber and steel railroad bridge that had been repurposed for trail use. when the ice dam caused its collapse, designers knew they needed to create a replacement that could withstand greater threats from flooding and debris. the snyder & associates team along with our structural subsidiary, 2022足球世界杯小组赛赛程 , were able to create a replacement bridge that far surpassed the structural stability of its damaged predecessor.

the final design for the new bridge is a much more solid structure that incorporates modern aesthetics with practical design applications. a customized led lighting system is incorporated into the design and is unique to a structure of this type. it not only illuminates the bridge deck and approaching trail path but also the underside of the bridge. the lighting system can be programmed to change colors in a near-unlimited pattern, sequence, or timeframe, creating a one-of-kind visual attraction for trail users and vehicle traffic on nearby interstate 80.

high trestle trail bridge

high trestle trail bridge over the des moines river, madrid, iowa.

the focal point of the high trestle trail is the impressively long bridge over the des moines river valley between madrid and woodward. constructed on existing concrete piers from a former railroad bridge, the snyder & associates team coordinated with 世界杯足球比赛预选赛 artist david dahlquist on the design of the bridge.

while the original steel girder railroad bridge was built at the location in 1913, it was replaced by the u.s. army corps of engineers in 1973 with a new 2,526-foot-long span to accommodate the increased hydraulic pressures created by the saylorville dam and reservoir project just 15 miles downstream. when the railroad went bankrupt a few short years later, the bridge sat largely unused for several decades. when the idea for the trail bridge was introduced, the massive concrete bridge piers had barely been “broken in” and could easily provide the solid footing needed for the trail bridge. the resulting structure is a major draw for not only recreational trail users but also railroad tourists who travel to the site to experience this grand reuse of a rail structure.

mark c. ackelson trail bridge

mark c. ackelson trail bridge over easter lake, des moines, iowa.

as part of the easter lake restoration project, a separate but coordinated component of the plan was the creation of a trail project to encompass the lake and connect with other area attractions. named in honor of the former iowa natural heritage foundation (inhf) president mark c. ackelson, the trail project was designed by the snyder & associates team and included a signature trail bridge.

the stunning ackelson trail bridge is located at the west end of the trail and serves as an impressive focal point with overlooks at each pier. the tranquil environment and magnificent views draw nearby residents, as well as regional visitors to experience this one-of-a-kind trail bridge and surrounding park.

around the world, bridges have long served as the hallmarks, gateways, and centerpieces of communities, providing connectivity that has a major impact on active transportation, tourism, and economic development. they can be an important part of community development and can even help to revitalize local economies. above all, pedestrian trail bridges can be more than just functional structures, they can be destination locations that attract tourists, create jobs, and provide recreational opportunities.

contact our team today to find out how we can create a one-of-a-kind structure that’ll improve your trail network and increase trail bridge tourism.
