Erosion and Sedimentation Control

Don’t let your project lose ground.

Erosion and sedimentation control prevents construction site erosion, as well as the discharge of sediment-laden water (muddy water) onto adjacent properties and roads.

Properly handled, it’s a routine aspect of any development or construction project. However, complications from improper erosion and sedimentation control can seriously impact the progress of your project.

Howell has  decades of experience with conservation districts throughout the region, and we have developed beneficial professional relationships with Department of Environmental Protection individuals who review Erosion & Sedimentation (E&S) Control Plans. We also stay up-to-date on the latest E&S regulations and design techniques—to make sure erosion and sedimentation control keeps your project on track and on schedule.

Sewage Facilities Planning Modules

Create smarter sewage solutions.

To ensure proper planning for all types of sewage disposal scenarios, Howell coordinates sewage facilities planning modules through the local municipalities, public and/or private municipal authorities and the Pennsylvania Department of Environmental Protection (PA DEP) for all of our subdivision and land development projects.

Howell has strong working relationships with Municipalities, County Health Departments, Treatment Facilities, Municipal Authorities, and the PA DEP—along with a strong track record of successful permitting strategies that are timely and cost-efficient solutions for our clients.

Floodplain Analysis

Predict and insure with precision.

With the latest flood analysis and hydrology technology, Howell can efficiently help property owners determine if their property is located within flood zones or floodplain. With FEMA frequently updating their maps—requiring more and more property owners to pay expensive flood insurance premiums—it’s important to stay on pace with the changes. Perhaps more importantly, it’s critical to have the ability to accurately determine actual flood zone elevations even where FEMA has not.

From single-family homes to large-scale community planning, Howell has the expertise to provide the precise, accurate information you need to understand how flood zones may affect your plans and your budget.

Many communities in southeastern Pennsylvania are within areas designated as Zone A. In these Zone A areas, flood delineations are “estimated” by FEMA and can vary by as much as 100 feet in some instances from the actual calculated or “modeled” flood zone boundary. In addition to requiring flood insurance, most municipalities have specific standards for building or developing in an approximate flood area. This is where Howell can help.

Utilizing the U.S. Army Corps of Engineers HEC-RAS River Analysis Program in conjunction with AutoCAD Civil 3D, Howell can determine flood levels more quickly and accurately than ever before. This gives you the precision intel you need, when you need it, to plan and execute your project with confidence.

FEMA Map Studies and Revisions

Get clarity on storm surge planning.

A FEMA Map Study is used to determine how high the water will rise in a particular water course.  In the study, storm surge levels are determined for the 100-year storm, and the areas within the storm surge are considered floodplains. This information is used to identify high risk flood areas, and to determine if flood insurance will be required for a particular property.

Howell uses state-of-the-art software to model storms and map floodplain boundaries, giving you the clear information you need to make critical planning decisions.

Highway Occupancy Permits

Accelerate your road work.

Any proposed work involving the Right-of-Way (R/W) of a State Road—for example, adding or modifying an access point (driveway, new street, parking lot, etc.) or utility work—requires a Highway Occupancy Permit (HOP). Obtaining an HOP involves submitting a Highway Occupancy Plan to the Department of Transportation (DOT).

default

This process includes completing a DOT Survey and Traffic Impact Study (TIS), and creating a Highway Occupancy Plan including stormwater management design, paving specifications, road profiles, road cross-sections, pavement marking plans, construction plans, signalization plans and other details.

The Howell team has extensive experience in all aspects of Highway Occupancy Permitting, which streamlines the process for our clients.

Building Permit Plans

Navigate permitting with efficiency.

Howell provides building permit plans as a service to not only large development companies but also individual property owners looking to build an addition or develop a single lot. We know the requirements necessary to obtain permits from any municipality, and have spent years building relationships with all governing agencies. This tends to expedite the process and alleviates unnecessary headaches for the applicant.

Pool Permit Plans

Make approval part of your pool planning.

If you’re considering an in-ground pool, you’ll need a building permit plan, also referred to as a pool permit plan. 

A pool permit plan is a lot plot plan showing the entire property, including the proposed pool or spa and its mechanical equipment and any driveways, walkways, parking areas, wells, retaining walls, utilities, easements, trees, or other structures. A survey may also be required depending on the location of the pool on your lot.

The Howell team is extensively experienced in creating thorough pool permit plans to satisfy municipalities and property owners alike.

Building Addition Plans

Add our expertise to your team.

Building an addition to an existing dwelling or any other structure on a previously approved lot requires a building addition plan, typically showing important details such as existing features, topography, utilities, and existing property lines as well as the new items being proposed.

Depending on the size of the project and overall disturbance area, an individual typically needs a property survey, architectural plans for the proposed structures, and often stormwater management design (to control additional runoff generated by the proposed structures). In some cases, the individual may need to obtain sewer and water permit approvals from applicable governing agencies.

Howell provides complete building addition plan services for large development companies and individual property owners. Our team is knowledgeable and experienced in the requirements necessary to obtain permits from any municipality. In addition, we’ve spent years building relationships with all governing agencies, which can expedite the process and help alleviate unnecessary headaches for the applicant.

Roadway Design

We have the drive to get cars moving. 

A Highway Occupancy Permit Plan is a plan required by the Department of Transportation to obtain a Highway Occupancy Permit (HOP).  A HOP is required whenever work is being proposed in the Right-of-Way (R/W) of a State Road.  Work that is typically done in the R/W includes adding or modifying an access point (driveway, new street, parking lot, etc.) or utility work.

A Department of Transportation Survey and Traffic Impact Study (TIS) are completed, and then Highway Occupancy Plans are done based on the work being proposed.  The Plans could require stormwater management design, paving specifications, road profiles, road cross-sections, standard notes and details, pavement marking plans, construction plans, signalization plans.

Land Planning

The smart way to understand your land.

Howell offers a wide range of services to help our clients determine the most viable design potential for both residential and commercial property applications. This includes the analysis of county and federal maps, tax maps, and survey and deed information in conjunction with municipal ordinance reviews to provide a preliminary analysis of properties. 

To minimize guesswork and financial commitment, we generate initial AutoCAD drawings to place proposed developmental ideas on paper for further analysis. As projects evolve, we use additional design information and more specific regulation requirements to refine layouts of proposed subdivisions, road systems, and building and parking configurations. 

In addition, we provide a full grading analysis to balance a site to its fullest potential – minimizing and/or eliminating the need to import or export earth materials from a site. We also offer extensive municipal ordinance review, which can help our clients seek relief from sites full of restrictive elements and ultimately bring your vision to reality.

We specialize in the following LAND PLANNING services:

  • Zoning Feasibility Studies and Planning

  • Ordinance Reviews

  • Site Analysis & Sketch Plan Design
  • Site Plan Renderings

Zoning Feasibility Studies and Planning

Consider your options from every angle.

A Zoning Feasibility Study from Howell helps you determine the developmental potential of a property or a group of contiguous properties.

To analyze zoning feasibility, we consider factors including boundary, topography and existing features (i.e. woods, streams, ponds, rock outcrops, etc.), along with design criteria and permitted uses in applicable zoning, subdivision & land development ordinances and other regulations. From this compiled data, we create a base plan which enables you to evaluate a property’s relative purchase and/or reasonable value.

Our Zoning Feasibility Studies can also provide a provisional layout to help a potential buyer decide if a particular property fits his or her needs. This approach is a smart, cost-effective way to minimize guesswork and provide objective clarity to any property in consideration

Ordinance Reviews

Crack the code on government regulations.

Howell provides a thorough professional engineering review of the applicable ordinances governing the development of your site. Our comprehensive review includes regulations at all levels of government—from the local municipality (borough, city, town, or township), to county, state, and federal governments.  From this review, we can determine the potential impacts the ordinance requirements might have on your particular project.

Taking advantage of our expert review early in the development process can help to determine the most cost-effective use and layout for your particular site—identifying any conflicts and defining permitted uses, lot coverage as it relates to floor area, parking requirements and environmentally sensitive areas where development is prohibited.

Site Plan Renderings

Visualize your concepts.

A site rendering provides a detailed, full-color illustration of a site layout, using colored shading to visually indicate the details of a project so that other stakeholders—partners, township officials, and the general public—can understand your plan, including impervious coverage vs. “green” areas and other important aspects.

To create a site rendering, Howell merges proposed and existing AutoCAD files to illustrate and define buildings, paving, sidewalks, grass, meadows and/or woods as well as tot lots, parks and stormwater areas.

This detailed illustration is an effective tool to help the public visualize and understand the positive potential of your project.

Site Analysis and Sketch Plan Design

A Site Analysis is performed to determine the developmental potential of a particular property and/or group of contiguous properties.

In order to complete a site analysis, data, such as boundary, topography and existing features (i.e. woods, streams, ponds, rock outcrops, etc.) is obtained and compared to design criteria and allowable uses permitted in the Zoning, Subdivision & Land Development Ordinances and other applicable regulations.  Information can be acquired in numerous ways such as Tax Records, USGS & County GIS Mapping, internet sites and available survey data which is then digitally assembled into a sketch plan.

 The sketch plan enables a client to consider a property’s relative purchase and/or an acceptable value.   It also assists in creating a proposed layout by which a potential buyer can decide if that particular property fits his/her needs with respect to its intended use.  This is accomplished with minimal financial commitment and eliminates and/or enlightens a buyer to potential pitfalls associated with the property.
