when summer winds down and students head back to the classroom, communities across the country experience a noticeable shift in traffic patterns. school zones fill with buses, crossing guards return to duty, and an increase in pedestrian and bike traffic brings new dynamics to local streets. at snyder & associates, we work closely with communities to design safe transportation systems. we know that a successful school year begins with a shared commitment to safety of vulnerable roadway users like student pedestrians and bicyclists.

be alert while driving near school buildings and college campuses, alike. college campuses, such as iowa state university, are likely to have students commuting at all hours of the day.

whether you’re a parent, commuter, cyclist, or student, here are four essential traffic safety reminders to keep top of mind this back-to-school season:

1. slow down in school zones

reduced speed limits during school hours. slower speed limits in school zones are crucial to conflict reduction and improved safety potential. reducing speed allows drivers more time to react and significantly decreases the risk of injury for pedestrians and bicyclists in the event of a crash. in many areas, school zone speed limits are strictly enforced during arrival and dismissal hours.

tip: always watch for flashing school zone signs and be aware of crossing guards or students near the curb, crosswalks and intersections. even if you’re running late, rushing through a school zone isn’t worth the risk.

2. watch for pedestrians and cyclists

students walking or biking to school often travel along residential streets with limited sidewalks or crosswalks. some younger students may not yet have the judgment skills needed to cross safely. motorists should be especially alert near intersections, mid-block crossings, and multi-use trails that intersect with roadways.

reduce speed in school zones and be prepared to stop. look for flashing school zone signs.

tip: approach all crosswalks with caution, especially those near schools or parks, and yield to pedestrians. additional tip: avoid blocking crosswalks with your vehicle when stopping at a stop sign or traffic signal.

3. know the rules around school buses

stay alert when following a bus and anticipate frequent stops. it’s illegal in all 50 states to pass a school bus that is stopped to load or unload children; yet this remains one of the most common and dangerous violations observed during the school year. when a bus extends its stop arm and activates flashing red lights, traffic in both directions must stop (unless on a divided highway).

tip: watch for children gathering at bus stops or crossing the street to board the bus.

4. eliminate distractions in drop-off zones

school drop-off and pick-up areas are busy. cars pulling in and out, children entering and exiting vehicles, and impatient drivers all create safety conflicts. distracted driving, even momentary glances at a phone or digital display can have serious consequences in these high-activity zones.

tip: stay focused and off your phone when driving in or near school areas. follow your school’s designated drop-off procedures and remain patient to help ensure everyone’s safety.

a shared responsibility

creating a safe environment for students is a shared responsibility between city planners, traffic engineers, school officials, parents, and drivers. at snyder & associates, we support this goal through thoughtful roadway design, school circulation studies, and safe routes to school 2022世界杯32强预选赛 . but the most immediate impact happens behind the wheel with each of us making smart, safety-conscious choices every day.

let’s work together to make this school year a safe one for every student, every family, and every community.

across the country, approximately 13% of children are supported by the individuals with disabilities education act (idea). yet many playgrounds still fall short of meeting their needs, lacking accessible routes, sensory-friendly elements, and opportunities for inclusive play.

that’s where inclusive design makes a meaningful difference. while ada compliance ensures essential features like accessible routes, transfer stations, and ground-level components, truly inclusive playgrounds go further. they are intentionally designed to engage children of all abilities, supporting physical, sensory, cognitive, and social development in safe, welcoming environments.

at snyder & associates, we’re dedicated to helping communities create spaces that promote connection, active lifestyles, and universal access. our expertise spans all-inclusive playgrounds, miracle league fields, and adaptive trail systems. we provide a comprehensive range of services, from community engagement and master 2022世界杯32强预选赛 to ada audits, site design, and construction documentation, to turn inclusive visions into reality.

we believe that parks and recreational spaces should reflect the full diversity of the communities they serve. the following examples showcase four inclusive playgrounds and parks designed to foster belonging and make a lasting impact.

1. all-inclusive playground & baseball field: ankeny miracle league

ankeny miracle league playground.

celebrated as a vibrant and inclusive space for children of all ages and abilities, the ankeny miracle league field has quickly become a cherished community asset. as the second miracle league field in iowa and the first to feature a co-located, all-inclusive playground, this park sets a new standard for accessible recreation in the state.

at the heart of the park is a custom-designed, rubberized turf field, offering a smooth, cushioned surface that’s free of obstacles, perfect for athletes using mobility devices. nearby, a shaded shelter with a concession stand supports family-friendly events and community gatherings.

what truly sets this park apart is its two-story, sensory-rich playground, the largest in ankeny, spanning over 14,000 square feet. this thoughtfully designed space isn’t just for weekend fun, it’s used regularly for miracle league games and serves as an outdoor play area for students at the adjacent terrace elementary school.

the ankeny miracle league park is more than just a playground. it’s a place where every child is encouraged to play freely, feel included, and be part of something special.

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

urbandale miracle league playground.

nestled among the little league fields at northview park, the urbandale miracle league field and adjacent all-inclusive playground are transforming recreation for individuals of all ages and abilities. these thoughtfully designed spaces provide a safe and welcoming environment where everyone, regardless of physical or cognitive ability, can experience the joy of play. whether it’s a game of baseball, a friendly round of kickball, or simply climbing and sliding, this park proves that fun has no limits.

snyder & associates played a key role in bringing this vision to life, delivering a wide range of services throughout the project. our team provided ada compliance reviews, park 2022世界杯32强预选赛 , sports field engineering, signage design, and even created a 3d video tour to help generate community support during construction. we also developed fundraising and promotional display boards for urbandale city hall and polk county 世界杯足球比赛预选赛 works.

what makes this miracle field truly unique is its versatility. while it was designed for baseball, city leaders plan to host a variety of inclusive events, ranging from kickball games to community festivals, ensuring the space continues to serve as a hub for connection, celebration, and inclusive fun.

3. park master 2022世界杯32强预选赛 : ames miracle league field & playground

at inis grove park in ames, more than 500 children and 300 adults with special needs in story county now have a place to play, connect, and thrive. the ames miracle league field and all-inclusive playground at inis grove park are designed to break down barriers and create lasting memories for individuals of all abilities.

by featuring equipment tailored to all skill levels and stages of development, the space invites everyone to play.

this transformative project is rooted in three guiding goals:

• promoting inclusive play and advancing social equity throughout the community.
• developing practical solutions to address both community concerns and site-specific challenges.
• inspiring community pride and investment through a visionary, meaningful space everyone can enjoy.

snyder & associates led the project from vision to execution, serving as the primary consultant and main point of contact for the city of ames and the miracle league committee. our team performed a detailed site inventory and analysis, reviewing natural features, existing park use, and circulation patterns to ensure the new amenities complemented and enhanced the broader park environment.

the resulting master plan honors the character of inis grove park while fulfilling the community’s vision for a space where everyone, regardless of ability, feels welcome and engaged.

4. inclusive playground & park improvements for pella’s kiwanis park

in pella, iowa, a project rooted in accessibility is reshaping the landscape of 世界杯足球比赛预选赛 recreation.

easy-access play structures and smooth playground surfaces ensure wheelchairs can move freely, creating an inclusive space for all.

spearheaded by wonder spelen (dutch for “miracle play”), this nonprofit initiative is dedicated to creating an all-inclusive playground where children of all abilities can experience the joy of play in a space built specifically for their needs.

at the heart of the project is the revitalization of kiwanis park into a regional destination that reflects the city of pella’s commitment to inclusion and ada compliance. in partnership with snyder & associates, the city developed a comprehensive master plan that blends pella’s iconic dutch-inspired aesthetic with universal design principles.

the playground features smooth, wide pathways, accessible surfacing, transfer platforms, and appropriately scaled play equipment, each element carefully selected to support independent, meaningful play for children of all abilities. the surrounding park was also enhanced to ensure seamless access and a cohesive, inclusive environment.

kiwanis park stands as a powerful example of what’s possible when a community views ada compliance not just as a mandate, but as a shared value. it’s a space where inclusion is intentional, access is universal, and every child is welcomed to play, grow, and belong.

understanding streambank erosion 

streambank erosion is a natural process, but when it accelerates due to human activity, weather extremes, and land use changes, erosion can threaten community infrastructure or buildings, degrade water quality, and impact ecosystems.

what does streambank erosion look like?

sloughing banks, bare soil, exposed tree roots, sediment in the water, and an overly widened channel are common signs of streambank erosion. unstable banks and downcutting often compromise nearby infrastructures such as roads, bridges, trails, and utilities, while sediment runoff deteriorates water quality and disrupts aquatic habitats downstream. additionally, bank erosion also deteriorates riparian habitat and access to water.

preventing erosion

the best approach to designing community assets (housing, commercial, parks, utilities, etc.) is to avoid impacts to natural resources that protect our watersheds: prairie, wetlands, floodplain, and streams. proactive communities adopt and enforce ordinances minimizing impacts to natural areas, such as stream buffer ordinances. stream restoration approaches also help maintain healthy riparian zones and manage stormwater.

how is it reduced?

we address streambank erosion by assessing our streams and combining engineering expertise with environmental science. depending on the site conditions and severity, our strategies to reduce erosion and improve channel stability may include:

• native plantings and live staking along the banks and in the floodplain
• rock structures such as bendway weirs or toe rock
• bank shaping to restore a more natural, stable slope
• constructing floodplain benches to reestablish connection between the stream and the 1.5 to 2 years floodplain
• remaindering or adding bends back into a straightened channel slows velocities
• out letting tile within the riparian buffer and letting tile water flow overland rather than out letting directly to a channel
• installing edge of field practices such as saturated buffers or bioreactors
• establishing riffles or other grade control structures to reduce streambed downcutting and slow water velocities
• utilizing beaver dam analogs

these strategies are designed to both protect infrastructure and enhance ecological functions. restoring natural stream functions and establishing riparian buffers builds long-term resilience against extreme weather events.

real-world solution in action: fourmile creek, central iowa

fourmile creek in spring 2025

one example of our long-term commitment to stream health is our work along fourmile creek in central iowa, where we partnered with the des moines metropolitan wastewater reclamation authority (wra), polk county conservation, and other local agencies to restore over 8,000 feet of severely eroded stream.

with the support of $4.2 million in srf sponsored project funding, our team designed and implemented cost-effective solutions, such as bendway weirs, toe rock, native buffers, and floodplain benches to stabilize streambanks, protect nearby sewer infrastructure, and improve water quality. this effort helped reduce sediment loads, enhance ecological function, and secure additional conservation land, reflecting the power of collaborative restoration to transform stream systems for lasting community and environmental benefit.

fourmile creek after construction in summer 2025

our team’s strategic 2022世界杯32强预选赛 and design efforts have improved not only fourmile creek, but also several other waterways, including sugar creek, buck creek, ioway creek, and the des moines river. each of these projects came with its own goals, landscapes, and technical considerations. by customizing our approach to the surrounding environment and community needs, we’ve supported long-term stream health , enhanced natural habitat, and contributed to more sustainable land and water management practices across the region.

whether we’re restoring rural streams or stabilizing urban creeks, our team delivers site-specific solutions that enhance environmental health while promoting 世界杯足球比赛预选赛 safety. we understand that healthy streams and buffers are an integral part of our communities, supporting everything from water quality and recreation to flood control and infrastructure protection. by reducing erosion within our waterways, we support the people, ecosystems, and neighborhoods that rely on them every day.

preserving the cultural ways of the past

the snyder & associates team is committed to balancing modern development with the preservation of our shared cultural heritage. recognizing the importance of protecting historical and cultural resources embedded in the landscapes where we work, we’ve integrated archaeological expertise directly into our operations. by doing so, we respect and preserve cultural legacies while advancing essential engineering solutions.

https://youtu.be/nybzzmkqzic?si=ryfnn_qqipq_jj_i

 

in-house archaeologist guides project efforts

to support our cultural preservation efforts, lina ramirez, our in-house archaeologist, plays a pivotal role in guiding projects through complex archaeological requirements. her expertise ensures that our work meets regulatory frameworks and helps safeguard important cultural resources, such as artifacts or historically significant sites that may otherwise go unnoticed in construction projects.

“lina brings cultural resources in-house so that we can provide improved services and expedited schedules to our clients,” explains jeff walters, environmental science group leader. “the urgency of funding and permitting requirements puts pressure on our project timelines, making lina’s involvement crucial to ensuring efficiency and regulatory compliance.”

key actions requiring cultural resource expertise

glass pieces found on site during a phase i archaeological assessment.

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.

preparing for a phase i archaeological assessment.

as lina explains, “the archaeological surveys required for our projects vary depending on the project’s specific regulatory triggers. we’ve seen this play out in projects ranging from mitigation banking to the complex permitting needs of the des moines water works transmission main project.”

for privately funded projects, archaeological requirements may arise if federal actions, such as obtaining a permit from the u.s. army corps of engineers, are involved. these actions often trigger the need for cultural resources reviews under section 106. our team’s deep understanding of these requirements helps keep projects on track, regardless of the complexity of the regulatory landscape.

a collaborative, cost-effective approach

the integration of archaeology into engineering at snyder & associates sets our firm apart. not only do we protect cultural resources, but we also streamline project management, providing a more efficient and cost-effective service to clients. having lina on staff eliminates the need for outside contractors and ensures that all cultural considerations are addressed in real time.

this collaboration transforms our firm into a multi-disciplinary entity that excels in both technical expertise and cultural stewardship. the result is a more responsive and compliant approach that minimizes potential delays and keeps projects on schedule.

if your project requires cultural resource work, let lina and our environmental team lead the way toward project success. contact us today to discover how our integrated approach ensures efficient project management, cultural preservation, and regulatory compliance.

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.

graphic from the soil and water outcomes fund showcasing the steps in a nutrient trading process.

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.

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.
