CLOMR/LOMR

A Conditional Letter of Map Revision (CLOMR) serves as FEMA’s feedback on a proposed project that could alter the hydrologic or hydraulic features of a flood source, potentially changing the existing regulatory floodway, base flood elevations (BFEs) or particular flood hazard area (SFHA). The CLOMR doesn’t revise the current NFIP map; instead, it assesses whether, if constructed as planned, FEMA would remove the project from the SFHA upon later submission as a request for a LOMR.

On the other hand, a Letter of Map Revision (LOMR) is FEMA’s alteration to an active Flood Insurance Rate Map (FIRM). LOMRs typically arise from physical modifications that impact the hydrology or hydraulics of a flooding source, potentially leading to changes in the regulatory floodway, BFEs, or SFHA. This letter goes into effect after a 90-day appeal period, along with the time required for advertising the appeal.

Drainage Reports

In civil engineering projects, drainage reports typically detail how a new or altered land use might impact local and regional drainage patterns and infrastructure. They often involve a thorough discussion and design plan to manage water quality impacts that may arise after construction. These reports encompass narratives, exhibits, and intricate calculations to support their findings.

Dry Utility Design & Coordination

In civil engineering projects, dry utility designs play a vital role. This involves planning, assessing feasibility, and coordinating with various utility providers (cable, electric, telephone, natural gas, and fiber optics) to ensure the necessary services are integrated into the project.

Erosion and Sediment Control Plans & Studies

Mass grading and general soil disturbance can be detrimental to the natural soil profile of developments, which can cause loss of topsoil and erosion. Erosion control practices work to prevent soil detachment and transportation. Sediment control plans are implemented to control sediment movement within and from leaving a project site. Plans and studies work to document these practices and provide instruction to developers and contractors for installation, maintenance, and reporting.

FEMA Coordination

When operating within a federally designated floodplain, FEMA coordination might become necessary. This involves assessing how floods affect the land and confirming if any development in the floodplain complies with the National Flood Insurance Program’s standards. The NFIP aims to minimize damage to insured structures situated within flood-prone areas.

Floodplain Modeling

Civil engineers can develop and employ hydraulic models, which simulate how water moves across different landscapes. These models can analyze how alterations to the terrain affect the speed and depth of water flow. These assessments are crucial for safeguarding individuals and property in case of flooding.

Grading & Earthwork Analysis

Preparing the ground for a new project or development involves grading and earthwork. Grading alters the contours and slopes of the land to set specific elevations and make it suitable for the intended purpose. Earthwork analysis is integral, determining the volume of soil moved (Cut/Fill) and whether additional material needs importing or excess material requires removal.

Hydrology & Hydraulic Modeling & Design

Computer models are commonly constructed to showcase hydrologic (rainfall and land runoff) and hydraulic (flow in channels and streams) processes. These models enable intricate simulations, illustrating the impact of these processes on surroundings, existing water systems, and proposed designs. This comprehensive analysis helps understand surface water flows, groundwater movement, flow measurements, floodplain and aquifer assessments, and watershed management planning, ultimately leading to improved designs.

Infrastructure Master Planning

A well-crafted master plan details the feasibility and overarching concepts required to deliver essential elements like roadways, access points, drainage systems, and utilities for a proposed project or development.

Parking Demand Studies

Each project has distinct parking needs, influenced by site limitations and anticipated usage. Parking demand studies aid in analyzing and designing parking facilities to improve the user experience while optimizing site efficiency.

Parking Lot Design

Parking lots are integral to land development. Well-designed parking facilities contribute to safety for both drivers and pedestrians. Considerations for their design encompass local regulations, zoning requirements, project location, intended use, access points, traffic flow, volume, and alignment with client objectives.

Paving Rehabilitation Analysis

As pavement ages and experiences increased vehicular use, a necessity for paving rehabilitation arises. Paving analyses involve visual assessments and measurements of existing pavement structures. These evaluations provide owners with estimated maintenance procedures to prolong the pavement’s lifespan.

Opinions of Probable Cost

Creating an estimated construction cost relies on historical and present costs of comparable projects, combined with experience and discussions with contractors. This estimation is crucial for every project, aiding owners in meeting their final objectives and ensuring projects remain within budget.

Roadway Design – Public & Private

Roadway design aims primarily to enhance safety, alleviate congestion, and offer better access, from private access roads to highways. It involves creating and executing plans for new collector roads, arterial streets, and highway projects or widening and improving existing roads in urban and rural settings.

Site Demolition Plans

The demolition plan specifies the scope and method for site and building features.

Site Design

A land development project commences with site design, a crucial foundation for success. This includes predevelopment site investigations, feasibility evaluations, site planning, and initial engineering considerations.

Site Structural Design

Site structural design covers various elements, such as retaining walls, foundations, stairs/ramps, drainage/utility structures, and pedestrian features.

Smart Infrastructure

Using technological innovations to form the site framework influences project design and helps to return a positive return on client or owner investment.

Storm Sewer and Drainage Design

A civil engineering stormwater management system may include pipes, manholes, inlets, ditches, detention/retention facilities, and other drainage structures. These elements are designed to handle stormwater runoff, convey it, and collect it effectively.

Sustainable Site Design Opportunity Analysis

A sustainable site design opportunity analysis reviews options to reduce negative environmental impacts, including water conservation, using site maintenance best practices, and optimizing for renewable energy consumption.

SWMP Reporting

Stormwater Management Plan (SWMP) reporting showcases project compliance with design standards to reduce pollutants in stormwater sewer systems. It encompasses routine and special inspection reports, observations, and recommended modifications to ensure adherence to these standards.

SWPPP Compliance and Auditing

A stormwater pollution prevention plan (SWPPP) outlines how a construction project will reduce stormwater pollution. An SWPPP audit reviews an existing plan for inefficiencies and recommends improvements for water pollution prevention.

Utility Infrastructure Design – Public & Private

Access to utilities is vital in any development, as it can significantly influence a project’s functionality, schedule, cost, and construction process. Evaluating existing utility availability and capacities alongside projected utility demands is crucial. This analysis helps identify the types of utilities needed, whether public or private. Civil engineering projects can design an effective and suitable utility infrastructure system by accurately assessing these factors and considering the client’s specifications and local regulations.

Vehicle Circulation Analysis

Vehicular circulation analyses ensure that cars, trucks, and commercial vehicles have ample space for turning movements within a roadway network or project site layout. It also focuses on facilitating their entry and exit from the civil engineering project site.
