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

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.

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.

view of a ground-mounted photovoltaic (pv) solar panel array installation.

across the country, the clean energy revolution has been quietly expanding its reach into the u.s. energy sector for several decades. because of renewable energy’s ability to reduce carbon pollution and minimize negative impacts on our environment, the increase in demand is only expected to continue. snyder & associates, as a multi-disciplinary engineering firm, has been at the forefront of this energy shift.

our team has provided professional services for dozens of ground-mounted photovoltaic (pv) solar panel array installations across the midwest and southwest on project sites ranging from twenty to several hundred acres. we’ve provided our services for all clients — from private owners/developers and engineering, procurement, and construction (epc) contractors to major energy companies.

snyder & associates’ extensive resume of real-world experience has solidified our understanding of renewable energy industry standards and enhanced our familiarity with federal, state, and local regulations and permitting requirements in countless jurisdictions. this in-depth knowledge allows us to navigate the regulatory process diligently and efficiently, keeping solar installation projects on budget and on time.

solar array installation from initial 2022世界杯32强预选赛 to utility interconnection

regarding ground-mounted solar array site development, snyder & associates does not believe in taking shortcuts. we realize the money invested in the initial stages can go a long way toward a facility’s successful operation in the future. a few critical steps in the initial 2022世界杯32强预选赛 process include topographic and alta/nsps land title surveys, phase 1 environmental site assessment (esa), wetland delineation, and stormwater pollution prevention 2022世界杯32强预选赛 (swppp). one important consideration when locating a solar array project is whether or not the site is physically appropriate for the technology. this can include whether the amount of physical space required for the array is adequate, the stability and slope of the soil on the site, and the proximity to the nearest interconnection point. our team will also note the current on-site vegetation and whether this will need pruning for construction and maintenance in the future.

solar site development demands effective & strategic civil design

adequate grading and panel spacing are critical for optimal solar array performance.

the 2022世界杯美洲杯预选赛 efforts at the core of our design work for solar array installations provide the underlying structure that allows solar power facilities to exist and operate. we can integrate the design by incorporating grading and stormwater mitigation constraints with the solar array layout early in the process. our designers can often balance any earthwork quantities on-site while designing efficient access roads that help minimize construction costs. we continually aim to minimize the amount of land disturbance on-site to balance each environment’s unique sensitivities.

the snyder & associates design professionals also have experience with solar racking and tracking products. site topography is thoroughly examined and can be cross-sectioned to determine if the natural lay of the land is capable of supporting the existing racking tolerances of the equipment to be used. our team utilizes civil 3d autocad software to ensure constructability is fully achieved. for solar installation sites that will disturb more than one acre of land during construction activities, a stormwater pollution prevention plan (swppp) is required.

snyder & associates considers the swppp a necessary and sound environmental practice. an swppp contains best management practices (bmp) for protecting the site from erosion and sedimentation through mitigation measures, such as native vegetation, swales, bioretention areas, and silt fences.

laying the groundwork for seamless construction staging & regulatory coordination

the extensive and diligent design efforts created by our team upfront are crucial to ensure ample space for on-site construction activities. construction staging, access, and lay-down areas are all critical for a successful build. this 2022世界杯32强预选赛 also positively influences bid prices, as a convenient construction site ultimately lowers the bid cost for the overall project. for our designers, coordination with regulatory agencies represents more of a scheduling challenge to the project rather than a technical complication. early coordination with these agencies is critical so that timelines toward approvals can be understood and planned appropriately. agency coordination partners typically include local townships, county zoning boards, state departments of natural resources, and occasionally the u.s. army corps of engineers.

snyder & associates has provided services for numerous solar energy projects across iowa, texas, new mexico, and nevada. when designing large-scale, ground-mounted solar energy facilities, our team can leverage a full range of 2022世界杯美洲杯预选赛 services to ensure that every goal is met for our client. our multi-disciplinary engineering professionals have the expertise to design solar array installation sites and all necessary site mitigations efficiently. we’ll thoughtfully balance the expectations in quality and cost while ensuring that the final product satisfies the highest professional compliance standards — for our clients and their customers.

harnessing the power of the people for effective 世界杯足球比赛预选赛 engagement

although the phrase “information superhighway” was coined nearly three decades ago, this vast network of unending data streams has only increased in the intervening years — with no signs of slowing down. without a doubt, this daily bombardment of constant information has made it increasingly difficult to get the attention of others. everyone is busy. people manage work, family, school, and a myriad number of other responsibilities.

how can we possibly take the time to volunteer for a focus group on a matter that greatly concerns us? where do we find time to attend a 世界杯足球比赛预选赛 meeting on a school night? how do we decide what to pay attention to?

active and effective 世界杯足球比赛预选赛 engagement leads to real-world thoughts and opinions from residents.

in the community 2022世界杯32强预选赛 world, these questions have made an effective 世界杯足球比赛预选赛 engagement plan a considerable challenge. time and attention are limited resources, but at the same time, the need for quality 世界杯足球比赛预选赛 input has grown to become a key component of many civic 2022世界杯32强预选赛 efforts. from comprehensive plans and urban revitalization endeavors to infrastructure design and construction projects, active 世界杯足球比赛预选赛 engagement plays a critical role in successful 2022世界杯32强预选赛 work.

the team of 2022世界杯32强预选赛 and design professionals at snyder & associates understands this crucial dynamic all too well. working at the forefront of 世界杯足球比赛预选赛 projects for several decades, we’ve fully embraced this shift for more active and inclusive 世界杯足球比赛预选赛 participation and have developed the tools necessary to reach the people in the most effective manner possible. whether you need smart content created to help market a project or a knowledgeable and polished team to present at 世界杯足球比赛预选赛 meetings, we’re able to help you fashion the best approach for reaching your goals.

our core strength, perhaps, lies in our commitment to our partnership with our clients. as true stewards of the community, our clients know their constituencies best. they know who the movers and shakers are, and they know which populations are underserved. as consultants, we possess the fundamental resources that allow us to act as a seamless extension of our client’s staff. our goal is to help them leverage our knowledge of 世界杯足球比赛预选赛 engagement best practices and combine it with their knowledge of their communities. this strategy effectively fills in the 世界杯足球比赛预选赛 engagement gaps, so together we can perform the most appropriate 世界杯足球比赛预选赛 engagement process for the project at hand and achieve the best result for the community at large.

unquestionably, our motives are personal. with twelve office locations in five states, the communities our team members serve are the same places we proudly call home. as a result, we’re able to better understand and address the challenges our clients face. for us, it’s about building long-term relationships with the people who place so much trust in us — knowing that we’ll not only do our best to address their needs but also the needs of all community stakeholders.

critical role of an active 世界杯足球比赛预选赛 engagement process

an effective 世界杯足球比赛预选赛 engagement strategy helps in the 2022世界杯32强预选赛 process in several ways — by increasing accountability and transparency, as well as acting as a vehicle to build trust and a mutual understanding. when determining the process for 世界杯足球比赛预选赛 engagement for any project, it’s important to understand the challenges you may face, the people you may encounter, and how much engagement is too much.

many community leaders are often left asking themselves, “what is the appropriate approach to educate residents on the crucial elements of a project so they can provide constructive feedback that helps our decision-making process?” or, “how can i reach our entire community when it seems like everyone is too busy to assist with our 2022世界杯32强预选赛 efforts?”

the elevate indianola campaign relied heavily on community input to guide the final report.

through our extensive experience, we’ve found a large percentage of residents in most communities do want to know what’s going on and, more importantly, would like to be part of the decision-making process. many simply don’t know how they can participate. oftentimes, certain factors play into people’s ability to attend typical 世界杯足球比赛预选赛 meetings or focus groups. these circumstances can encompass lack of childcare or transportation to the meeting location, communication barriers, or their work schedule conflicts with the meeting time. and some people are simply intimidated by a civic building setting or have a fear of speaking out in a 世界杯足球比赛预选赛 setting. our job as planners and designers is to recognize the roadblocks that keep these citizens home and work to mitigate them.

some groups may be harder to reach but they’re equally important in the decision-making process when decisions directly impact them. additionally, these groups may have different perceptions of the community’s strengths and weaknesses and different priorities for improvement. having a full understanding of the demographic helps to ensure you’re reaching everyone in the community in an equitable manner.

certain 世界杯足球比赛预选赛 engagement efforts involve a steering or advisory committee to make decisions for the plan. a goal to consider when assembling this committee is to always attempt to reflect the unique demographics of your community. since steering and advisory committees are typically fewer than 20 people, creating additional ad-hoc subcommittees that report to the primary committee is one way to ensure more demographics have adequate representation. snyder & associates has the tools to help assist in designing an appropriately sized 世界杯足球比赛预选赛 engagement process that has the capability of reaching audiences of varying sizes, up to and including your entire community.

improvements in consultative engagement approach & technology lead to better results

government employees know all too well that 世界杯足球比赛预选赛 participation is a requirement for most projects in their communities. in years past, a widely adopted 世界杯足球比赛预选赛 involvement process looked something like this:

• a 世界杯足球比赛预选赛 information meeting is held where a government representative presents the project.
• citizens in attendance ask questions and the representative answers those questions, and then the project moved forward.

in some instances, these informational meetings led to slight tweaks in the project to better meet the needs of those members of the 世界杯足球比赛预选赛 that attended the meeting — and were willing to speak up.

in recent years, however, communities are adopting (and expecting) a more robust process specifically tailored to each project. technology has expanded exponentially, thus allowing communities to reach broader audiences and to gain additional feedback as they move through the development phases of their projects. our team of planners has embraced these new tools that bring residents into the fold earlier in the project development process  and involve:

• marketing campaigns
• consultative approach
• involvement and collaboration efforts

snyder & associates prides itself on being on the cutting edge of new ideas and technology that have a positive impact on our work and our client communities. in our world, effective 世界杯足球比赛预选赛 engagement should always be tailored to your specific project and the demographic you’re trying to reach. and while no two 世界杯足球比赛预选赛 engagement campaigns will look the same, they should utilize established guidelines that promote the right approach for your project. contact our 2022世界杯32强预选赛 and design professionals today. let us help you explore how we can craft your next 世界杯足球比赛预选赛 engagement campaign.

to protect human health and the environment, the environmental protection agency (epa) strictly regulates waterways in the united states. whether you’re a private landowner, a for-profit developer, or a 世界杯足球比赛预选赛 or private agency or organization, the clean water act (cwa) is the primary law governing water pollution. the cwa also requires specific permits to be obtained before construction or development occurs near u.s. waters. the rules for one of these permits can be found in section 404 of the cwa. specifically, section 404 seeks to avoid or minimize losses to wetlands and other waters of the united states (wotus) by regulating the discharge of dredged or fill material. this includes altering or filling a jurisdictional water body for any of the following reasons:

• commercial or residential development
• water resource projects (i.e., levees and dams)
• waterway enhancements (e.g., county or state parks)
• infrastructure projects (i.e., roads, bridges, trails, and airports)
• mining and resource extraction operations
• various other operations

one goal of the 404 permitting program is to encourage landowners and developers to consider practical alternatives that may be less damaging to the wotus and that any action taken will not significantly degrade a protected body of water. the mere act of applying for a permit means that you can show that steps have been taken to avoid impacts to nearby waters and, where unavoidable, the potential impacts have been minimized. for those projects that simply can’t avoid impacting a wotus, 404 permitting acts as the equalizer. the issuance of the permit assures that any adverse effects on a protected body of water are mitigated and that compensation will be provided for all remaining unavoidable impacts. the idea behind 404 permitting isn’t to prevent progress or make it difficult to complete projects — it’s to ensure the quality of the nation’s waterways for future generations.

experienced professionals to handle complex rules

complex waterway projects benefit from the services of a full-service, multi-disciplinary organization.

navigating the complexities of the 404 permitting process requires the services of a knowledgeable and trusted partner. the professional staff at snyder & associates has almost two decades of experience performing this service for our clients. led by principal environmental scientist jeff walters, our team is fluent in handling all permit types (more on this later), and we’ll work with the regulatory body to ensure your permit is completed as efficiently as possible. as part of a multi-disciplinary organization, our environmental scientists can handle any stand-alone wotus project that requires 404 permitting.

additionally, our team is backed by an entire staff of civil and structural engineers to coordinate on larger projects that may have a water component, such as a bridge or dam. and because the clean water act is a fluid document that is periodically revised due to new legislation, you’ll benefit from engaging an experienced team that works tirelessly on your behalf using the most current information.

new navigable waters protection rule (nwpr)

the introduction of the navigable waters protection rule (nwpr), finalized in january 2020, is a recent example of changes that can occur to the clean water act. the nwpr establishes a new definition for waters of the united states that revises the 2015 definition. in short, the nwpr creates four categories of jurisdictional waters federally regulated under the cwa and twelve categories of excluded waters and water features. the four categories of jurisdictional wotus defined by the nwpr are:

• territorial seas and traditional navigable waters (tnw)
• tributaries
• certain lakes, ponds, and impoundments
• wetlands adjacent to jurisdictional waters

within these four categories of jurisdictional wotus, fundamental changes that we’ve identified as having the most significant impact on our clients include:

• removal of jurisdictional status for ephemeral streams
• lakes, ponds, and impoundments are jurisdictional only if they have connectivity to tnw and tributaries
• wetlands adjacent to tnw, tributaries, ponds, lakes, and impoundments are jurisdictional, even if they have a physical separation
• ditches may have jurisdiction under certain circumstances

the list of waters excluded from jurisdiction as defined by the nwpr is as follows:

view of a typical, non-jurisdictional ephemeral drainageway located in a farm field.

• waterbodies not included in the four categories listed above
• groundwater
• ephemeral features
• diffuse stormwater run-off
• ditches not identified as wotus
• prior converted cropland (pcc)
• artificially irrigated areas that would revert to upland if irrigation ceased
• artificial lakes and ponds
• water-filled depressions incidental to mining or construction activity
• stormwater control features
• groundwater recharge, water reuse, and wastewater recycling structures
• waste treatment systems

despite these changes, the workflow process for identifying wotus, including wetlands, still includes the completion of a wetland and stream delineation-first. also, hec-ras modeling can be used with a field delineation to perform inundation mapping and create inundation depth datasets. the use of hec-ras modeling benefits our clients by verifying the jurisdiction of a wetland or stream. this, in turn, should reduce the usace review process when determining jurisdiction on complex projects.

the changes brought about by the nwpr have a more significant impact once wetland and stream delineations are completed and the permitting phase of a project begins. the u.s. army corps of engineers (usace) is responsible for issuing section 404 permits and monitoring their compliance. as usace district offices begin phasing in these new rules, our team will continue questioning and challenging district decisions to serve our clients best. our thorough understanding of the new nwpr definitions ensures we can better advocate for our clients and help streamline the permitting process.

working with the usace

permitting a project with the usace shouldn’t cause project delays and cost overruns. when handled by experts in the field, it’s similar to securing a building permit from a city or county office. having performed nearly 500 wetland delineations over the past 20 years, our team ensures that every project is permitted appropriately, on time, and without any added expense. we’re well-versed in the nuances of section 404 and have forged relationships with the critical decision-makers in most district usace offices — one of the many vital, unseen benefits we bring.

three critical elements to obtaining a usace permit successfully are understanding impacts, the appropriate level of documentation, and time. section 404 permits fall into one of three categories: nationwide (nwp), regional (rp), and individual permits (ip). the usace typically only issues two of these types: nwps and ips. the main difference between an nwp and an ip is a project’s scale of impact on aquatic resources, including rivers, streams, and wetlands.

the usace will issue an nwp when impacts to wetlands are less than one-half acre and separated from the nearest river or stream by less than 300 or 500 linear feet, respectively. when impacts exceed these thresholds, the usace will issue an ip. an ip requires additional documentation, including threatened and endangered species reviews, alternatives, analysis, and cultural resources investigations. it should also be noted that all projects exceeding one-tenth acre of wetland impacts and/or 300 linear feet of stream impacts require mitigation.

most nationwide and all individual permits require a wetland and stream delineation to identify wetland and stream boundaries within the project site. the delineation report includes the project location, purpose and need of the proposed action, and a summary of findings. impacts are determined by transferring the delineated wetland and stream boundaries into the project design plans.

snyder & associates uses the wetland delineation reports and design plans to fill out the usace permit application form directly. turnaround time for receiving an nwp is typically 6-8 weeks, while an ip is generally accepted in about 180 days.

early professional involvement beneficial for obtaining 404 permitting

we recommend engaging our environmental sciences staff early in the project scope whenever possible. this allows us to best serve you by determining the documentation and time required to obtain a usace permit and to ensure the permitting process is completed as efficiently as possible. however, we fully recognize that a lack of understanding of permitting requirements or existing property conditions can delay seeking outside support. and that’s not uncommon. so even if our professionals aren’t consulted until late in the game, we’re still equipped to complete the job successfully.

the post 404 permitting plays a critical role in the health of our nation’s waterways first appeared on 华体会英超赞助商 - engineers and planners.

as we face growing concerns over the environment and climate change, protecting the world around us is more important than ever before. for over 40 years, section 404 of the clean water act has aimed to regulate the discharge of pollutants into rivers, lakes, streams, and wetlands, which are a vital source of drinking water and an integral component of the environment. “section 404 aims to minimize impacts to waters of the u.s,” shares nichoel church, pws, environmental scientist for snyder & associates.

the u.s. army corps of engineers (usace) is responsible for enforcing section 404 of the clean water act, which requires a permit for any project that discharges fill or dredges material into the waters of the united states (wotus). generally speaking, church says permit applicants must demonstrate that discharge won’t significantly degrade the water it’s discharged into and review alternative options. if impacts are imminent and expected to exceed permit thresholds, compensatory mitigation is required. through mitigation, the applicant offsets the environmental impact by purchasing mitigation bank credit, in-lieu fee credit, or replacing what was lost through permittee-responsible mitigation.

mitigation might sound intimidating for landowners, developers, municipalities, and others, but it doesn’t have to be. as church points out, there’s a permitting process in place, and mitigation bank credits are available in many states to streamline mitigation requirements. “for example, in iowa, mitigation banks are designed specifically for the purpose of offsetting unavoidable impacts to emergent wetlands, forested wetlands, and streams,” she explains. “they provide the opportunity to quickly and efficiently mitigate permitted impacts and comply with the clean water act, so there’s no net loss to the environment.”

understanding basics of mitigation banking

a mitigation bank uses a credit and debit system to offset impacts to wotus in a specific service area. credits are improvements that are available for purchase. debits result from permitted impacts to wotus. mitigation banks are found in two forms or a combination of both:

• wetland mitigation bank — a property containing at least 25 acres of improved or created wetland. improvements include enhancing vegetation and restoring hydrology.
• stream mitigation bank — a segment of a stream that’s been improved to benefit the watershed. improvements include reshaping slopes for stabilization, adding in-stream structures such as bendway weirs, or removing dams and other obstructions.

the amount of credit available for purchase is determined by the level of functional lift an improvement will provide. the method used to determine credits varies by state. in iowa, the iowa mitigation banking guidance and iowa stream mitigation method (ismm) determine credits. in terms of size, the general rule of thumb is to use 25 acres or more for a wetland mitigation bank and 2,500 linear feet of stream for a stream mitigation bank.

the development of a mitigation bank

the individual or entity who owns the mitigation bank is known as the sponsor. the sponsor goes through an approval process with an interagency review team (irt) that includes the u.s. army corps of engineers (usace), u.s. environmental protection agency (epa), department of natural resources (dnr), u.s. fish and wildlife service, and other agencies to provide mitigation credits for purchase.

through the irt approval process, proposed improvements for a mitigation bank are extensively reviewed, and credit amounts are determined according to the level of anticipated environmental lift. once the approval process is complete, initial credits are released and available for purchase. after construction is finished, more credits are released according to a credit release schedule. any remaining credits are released after each successful year of monitoring and the irt’s review of the monitoring report.

mitigation bank success is rewarded with credit releases. failures result in adaptive management, withheld credits, and the irt could ultimately terminate the mitigation bank. the approval and monitoring process requires 2022世界杯32强预选赛 , documentation, and foresight, so professional guidance is often helpful.

“we can help a sponsor navigate the approval process with the review team to keep things moving forward,” says church. “through our work with six successful mitigation banks along with numerous others currently pending in iowa and nebraska, we’ve developed a deep understanding of the mitigation bank process, standards, and requirements.”

wetland mitigation bank credits are generally sold on a per-acre basis. in iowa, an emergent wetland credit can range from $35,000- $75,000, while a forested wetland credit may cost between $45,000- $105,000. currently, stream mitigation credits sell for $35- $114 per credit in iowa. however, credit cost varies by state, impact activity, wetland function, and credit type. in addition, different states use different methods of determining the level of mitigation required for environmental loss. for example, in iowa, stream credits are determined using the iowa stream mitigation method calculator. missouri and several other states have their own method of determining mitigation for stream loss. minnesota and oregon utilize wetland function and value assessments, which can require additional mitigation.

steps towards purchasing credits

snyder & associates experts conducting a site walk at niebuhr stream mitigation bank.

if a jurisdictional stream or wetland will be permanently filled or altered, a section 404 permit is required under the clean water act. snyder & associates is often the authorized agent, which allows us to obtain section 404 permits on behalf of our clients. our client is called the permittee. the permittee is ultimately responsible for ensuring permit compliance. sponsor contact information and credit availability are located on a website called ribits, which stands for the regulatory in-lieu fee and banking tracking system. this website is owned and managed by the usace.

the permittee or authorized agent discusses mitigation requirements with the usace during the permitting process. the permittee is responsible for completing mitigation. if the purchase of mitigation bank credits is required, a mitigation bank application is filled out and payment is sent with the application. the mitigation bank sponsor receives the application, processes payment, debits the credits from their ledger, and sends the permittee a proof of purchase. the permittee forwards the proof of purchase to the usace, and the usace deducts the purchased credits in ribits to complete mitigation.

permittee-responsible mitigation

permittee-responsible mitigation allows a project owner to construct or enhance a wetland or improve a stream and monitor its success. this option is only available for projects that are outside of a mitigation bank service area. it requires applicants to submit a mitigation plan. then, permitting agencies and the applicant(s) come to an agreement on the location, construction requirements, and monitoring. monitoring may be required for up to 10 years. annual reports are submitted to the permitting agencies to prove the success of the mitigation site. if a mitigation site fails or is unsuccessful, it must be replaced or mitigated by purchasing bank credits.

benefits mitigation banking

• environmental stewardship — agency approval and ongoing monitoring ensure mitigation bank success of improvements and environmental lift techniques.
• mitigation efficiency —  purchasing mitigation bank credits is a fast, effective way to meet 404 permitting requirements while avoiding the need for costly maintenance and monitoring of permittee-responsible mitigation.
• maximize land use — permittee-responsible mitigation can slow development and change intended plans for land use. mitigation banks provide an opportunity to maximize land use while offsetting the impact in a nearby location.

navigating the path to mitigation banking success

there’s no way to be sure what mitigation needs your project may require without thorough review and analysis as well as early coordination with permitting agencies. whether you’re looking to realign a straightened stream or develop a piece of property near a wetland, professional expertise will help sort out the details. an onsite review such as a wetland delineation or stream assessment will identify the presence of u.s. waters in your project area. using the information that results, you can prepare and plan for mitigation to keep your project moving forward and within budget. “every project is different, and mitigation requirements vary by state,” says church. “we can help you gain an understanding of the level of mitigation your project will need and explore the credit opportunities available to you.”

aerial drone imagery of u.s. 151 near anamosa complemented traditional survey methods.

survey technology is soaring to new heights with the addition of unmanned aerial vehicles (uav) or drones, as more commonly known. when fitted with gps technology and a high-resolution camera, these drones are often called unmanned aerial systems (uas). these remotely flown aircraft, equipped with a full package of software and hardware, offer a new approach to construction progress, observation, and monitoring, including photos, videos, and traffic studies.

in the land survey field, drones add an entirely new dimension with their ability to provide aerial photogrammetry, 3d site modeling, photo comparisons, and aerial video. they’ve even shown their value in determining stockpile, basin area/volumes, and infrastructure inspections. with a forward-looking approach to land survey and 2022世界杯美洲杯预选赛 design, the snyder & associates team is excited to provide their clients with a deeper bench of solutions using the eyes in the sky their drones offer. “all of the service offerings we provide will benefit from this technology and the data a uav provides,” shares snyder & associates surveyor ted jansen. ” we can swap different cameras, thermal imaging units, and other components to provide different project efficiencies for our clients.”

determining which project types benefit from a drone survey

every survey project begins with a discussion of the overall project needs to determine how the survey fits into the big picture and what survey methods are applicable. site accessibility, constraints, and project limits are essential for selecting an appropriate aerial flight. here are some common questions that help determine if an aerial survey would be beneficial.

an ortho-mosaic image of u.s. 151 was used to create a 3d model of the project site.

• what surrounds the project site?
• what are the ground cover conditions?
• what deliverables are needed, and when are they required?

every project is different, and not all sites are accessible for aerial services. realistic expectations need to be made, taking timing and weather into account. if the ground can’t be seen from the sky, the accuracy of an aerial survey is diminished. project sites within five miles of certain airports require faa authorization before an aerial flight can occur, which typically takes two days and two weeks to receive approval. evaluating the wide range of factors that influence site accessibility and your project needs and goals helps maximize the use of resources and project funds.

operating a drone for land survey 

this is a visual depiction of an autonomous flight program during work on iowa u.s. 75 near sioux center. the 3d modeling of the project corridor was instrumental in providing citizens with a first-hand view of the proposed project details before construction began.

the uav can be flown manually or fully autonomous with manual backup. a fully autonomous flight follows a predetermined plan designed by the flight team. during an autonomous flight, data is collected and processed using cloud-based processing software that transmits to a tablet. an faa part 107 certified uas pilot monitors the flight from the ground to ensure safe uav operation. the site’s existing topographic features determine the altitude of the flight, and the altitude determines the image resolution.

as altitude increases, resolution deteriorates, diminishing image clarity and the accuracy of the surface data. on the other hand, higher altitudes decrease survey flight time and data file size, decreasing costs and allowing a more efficient file size. the maximum altitude that a commercial uas is typically allowed to fly is 400 feet above ground level (agl). while it’s usually a breeze to fly a uav and gather data, more goes on behind the scenes to make that data usable. a uav provides a point cloud with georeferenced coordinates and elevations to create a surface at many locations. design technicians analyze and process the uav’s data to produce the desired deliverables.

best projects for drone use

drones can assist with a variety of 2022世界杯美洲杯预选赛 projects. however, there are specific instances where a drone may be recommended:

• safety — rough terrain, heights, and other circumstances that pose safety risks to survey and engineering staff
• level of detail — uavs can be flown at low altitudes to gather high-resolution data that rivals traditional survey methods
• project 2022世界杯32强预选赛 , progress, & closeout — uavs can help capture existing site data, which is valuable in assisting with land 2022世界杯32强预选赛 and phasing. in addition, as the project progresses, a uav can be used to track project milestones and provide aerial images of the result.

can drone surveying replace a traditional survey?

a uas will not eliminate the need for on-site surveyors or traditional survey methods. instead, it’s designed to enhance current survey methods by offering greater detail and better coverage of the information gathered. ted and his colleagues have determined that utilizing the uas increases the usable data available for design while reducing time in the field and increasing the team’s efficiency. regarding accuracy, the horizontal and vertical errors of the uas cannot be less than the site control points and the method by which these control points are obtained. control point placement on the project site, logging, and processes will determine the overall accuracy of the flight survey. boundary surveys, underground utility surveys, bathymetric surveys, and the need to verify and check aerial survey data will always be required and remain a common practice.

using uas technology on your next project

snyder & associates provides comprehensive services and utilizes various cutting-edge technologies to gather data efficiently and accurately. whether you have environmental disturbance or site access concerns or would just like to get a bird’ s-eye view of site topography, uas can be beneficial. contact eric miller to learn more about snyder & associates’ uas program and explore opportunities for uas technology on your next project.

when dennis snyder and steven rowe established snyder & associates in 1977, land survey comprised most of the business. forty years later, it remains a crucial service we provide as a comprehensive engineering and 2022世界杯32强预选赛 firm.

“survey is one of our firm’s core services,” shares mike geier, pls, council bluffs business unit leader, chairperson of the board for snyder & associates. “from land to engineering survey, our surveyors perform a key function in the overall makeup of our practice.”

since dennis and steve opened for business, snyder & associates has grown from a two-person team to include more than 200 professionals. spread across five of our twelve midwest offices, our survey team of over 40 skilled individuals provides various services, including topographic, hydrologic, and right-of-way surveys, construction staking, subsurface utility mapping, and more.

“although the fundamentals of survey remain the same, how survey work is performed today has changed dramatically since the early days,” notes eric miller, pls, snyder & associates survey business unit leader. “along with normal tools, it’s not inconceivable that a survey crew could have with them on any given day a variety of technology including a robotic total station, a glonass gps rover capable of connecting to a statewide network, a terrestrial hds laser scanner, an autonomous/remote controlled hydrone with sonar depth readings, and subsurface locating equipment. being versed in this evolving technology and applying the appropriate tools to the job of land surveying are key factors to project success.”

land surveying & its importance on engineering

surveyors provide the foundation for sound engineering. the precise information they collect regarding the shape and contour of the earth’s surface is the starting point for 2022世界杯32强预选赛 projects and developing solutions.

“it’s typically the first and last phase of an engineering project,” explains geier. surveyors are responsible for gathering existing information for the basis of design and conclude by documenting the as-built condition of the completed project.

national surveyors week, hosted by the national society of professional engineers, takes place annually during the third week of march and aims to raise awareness of the profession through education, media, and 世界杯足球比赛预选赛 service. in honor of national surveyors week and the critical role surveyors have played in our firm’s success, we recently sat down with survey staff members to learn more about the profession.

i am one of four hundred professional land surveyors in iowa. the number of professional land surveyors has been decreasing every year. if you want a highly demanding career, look no further than becoming a professional land surveyor. — erin griffin, pls, land surveyor

i would encourage someone considering entering the survey profession to think about the different avenues within the field. there is a variety of routes that a surveyor can take that would line up with individual strengths and interests. although challenging, every surveyor i talk with seems to very happy with their choice of profession. it was an excellent route for me. — eric miller, pls, survey business unit leader

keep calm. i am a land surveyor. now, let the fun projects begin. — ted jansen, land surveyor

as a foundational part of our firm, we understand the need for accurate land surveyor data to ensure the success of any of our engineering projects.

what types of 2022世界杯美洲杯预选赛 projects do you enjoy most and why?

i enjoy development projects. typically, we work with the development engineers to provide preliminary surveys, boundary surveys, final plats, easement plats, and construction layouts. a survey is always the beginning and end of a project, so its nice to see it through its entirety. — erin griffin, pls, land surveyor

i enjoy working on projects that require a heavily involved, detailed building design. we perform all of our survey calculations to lay out buildings in the correct location accurately. coordination with the project design team is paramount in these types of projects. take the des moines principal financial corp 1 building restoration project, for example. it involved surveying structural component locations built in 1939, capturing survey data accurate to a thousandth of a foot, and working closely with the architect’s design team to calculate proposed structural components. it was also unique because it involved the construction of a skywalk between the existing principal financial building and a new one across the street that was in the preliminary stages of construction. the design teams from both projects worked closely throughout the entire process to make both projects connect as planned. — ted jansen, land surveyor

there’s a high reward in some of the complex, more extensive, multi-year projects that require thoroughness and attention to detail. initially, these projects can feel overwhelming, but when they are completed well and the project is successful — it’s an excellent feeling. on the other hand, projects i can work on directly with the owner are also fun. for example, preparing a letter of map amendment, or loma for short, that removes a mandate placed on a property owner to carry flood insurance, saving them thousands of dollars over the life of property loan, is very satisfying. — eric miller, pls, survey business unit leader

what are the top two challenges you face as a land surveyor? 

the first challenge is recruiting new surveyors. only two colleges have a two-year 2022世界杯美洲杯预选赛 /land surveying program in iowa. the second challenge is training the latest generation of land surveyors that technology has its limits, meaning it can’t interpret deeds, easements, and evidence to retrace the steps of the original surveyor. — erin griffin, pls, land surveyor

the availability of college graduates entering the surveying field is a concern. some colleges have limited survey exposure, and others have dropped their programs altogether. i also think survey technology is adapting very quickly. this can be a challenge for some that adapt slowly. — eric miller, pls, survey business unit leader

why should someone consider a career as a land surveyor?

if you love the outdoors, working directly with clients, and coordinating your schedule, then surveying is the career for you. it is very intriguing to be involved with the steps that transition a farm field into a multi-story development in just a few months. satisfaction is gained knowing that our clients are taken care of. that level of satisfaction shows when clients call upon us repeatedly to help coordinate their next successful project. —ted jansen, land surveyor

there are many disciplines within the survey profession, so there’s no limit to the type of work you can purse. there’s a place in this career for tech geeks, outdoors people, historical researchers, builders, ect. — eric miller, pls, survey business unit leader

in your opinion, what types of skills or traits are essential to have as a surveyor?

a respect for history is essential. as one of the world’s oldest professions, a lot of history can be dug up in the research for a property. a surveyor must know how to apply this history and use it to assist the team in making the best decisions for a project. —ted jansen, land surveyor

sediment loss and soil erosion from construction sites are recognized as some of the most significant water pollution sources across the country. according to the environmental protection agency (epa), sedimentation causes approximately $16 billion in environmental damage each year. with bare soils commonly exposed at these sites, a single rain event can cause erosion, causing sediment transport in stormwater into nearby storm sewers and eventually into watersheds.

from 2022世界杯32强预选赛 to practice: incorporating erosion control into any project

native plants and grasses, like those utilized within the prairie heritage civic center plaza, add to the aesthetic appeal while assisting with stormwater management and infiltration.

snyder & associates combats soil erosion by utilizing best management practices (bmp) on worksites, along stream banks, and at various other locations across the midwest. incorporating sediment and erosion controls in our designs also keeps soil off city streets, prevents constant dredging of lakes and rivers, reduces the growth of harmful algae, and creates a healthier overall environment.

native vegetation is a natural erosion control practice

adding vegetation to bare soil areas is the most common and natural erosion control method practiced. native vegetation species, such as wildflowers and grasses, are ideal for sediment control situations. these plants are adapted to the geographical area, need less care than many non-native plants, and attract local wildlife like birds and butterflies. when a senior living community in wisconsin decided to expand its facilities, our professionals recognized the hilly landscape as a potential erosion threat. the snyder design team worked to incorporate attractive and functional landscaping into the overall plan, reducing erosion during construction and the coming years.

soil binders are effective for temporary stabilization

another prevalent erosion and sediment control method is soil binders. this practice is typically applied to disturbed areas requiring short-term protection and in combination with other bmps. soil binder options vary from project to project as they differ in longevity, suitable soil type, and cost. therefore, it is important to work with a team such as snyder & associates, who have the expertise to help select the soil binder that meets your site’s needs.

soil binders are being applied to a disturbed project area.

at fourmile creek, our team sprayed a binding substance along the riverbank, protecting the exposed area and allowing native vegetation time to grow.

riprap permanently protects soil from erosion

along riverbanks or shorelines, a permanent erosion prevention solution is necessary to combat strong flows and flooding. a layer of large stones or boulders called riprap is often placed at bank areas where erosion potentials are the highest. this layer armors, stabilizes, and protects shorelines against erosion and scour in areas of concentrated flow or wave energy.

when a sharp meandering creek in west des moines required adjustments to accommodate a new bridge, our environmental experts worked to reduce the system’s overall erosion in conjunction with the realignment. after incorporating riprap and rock riffles, which slow stream currents, water flowing through the project site now appears clearer than water upstream and downstream, signaling that the area’s erosion control measures are working. as a multi-disciplinary firm, snyder & associates’ team works daily with all types of clients, providing extensive 2022世界杯美洲杯预选赛 services. no matter what sector a project falls under, our experts are trained to incorporate erosion and sediment control practices, helping to reduce erosion and its environmental impacts.

guiding project success through regulations & permitting

before work begins on a project, it’s necessary to obtain the required permits. any project that discharges water from its site into local water systems must possess a national pollution discharge elimination system (npdes) permit. this policy is vital in keeping pollutants like lawn care fertilizers, uprooted soil, oils from roadways, and many other contaminants out of our water systems.

rip rap is placed on the shorelines where erosion potentials are highest.

the experts at snyder & associates excel in their mission of helping communities meet npdes compliance requirements throughout the design of projects. specifically, our team is well versed in creating precise stormwater pollution prevention plans (swppp), a required step in the npdes process.

an swppp lists proactive measures our experts intend to use to limit the spread of pollutants to rivers, streams, and lakes. the design, execution, and monitoring of an swppp entails a significant amount of expertise and resources to make the project a success. if construction site runoff is not addressed correctly, regulatory agencies can impose substantial fines and penalties. the cost of noncompliance in the process is significant, and snyder & associates utilizes our extensive experience to eliminate that risk.

erosion control measures create significant improvements

the timely use of effective erosion and sediment control practices combined with on-site construction administration helps our team consistently achieve project goals. we recognize the stabilization of these susceptible soils has lasting impacts long after construction is completed.

whether you’re looking for assistance with complete design and 2022世界杯32强预选赛 or just implementing control measures in your project, it’s always best to work with an expert like snyder & associates. we understand the erosion and sediment control options, processes, and tools necessary to make your project compliant.
